<SOH> BACKGROUND ART <EOH>Recently, it has been required to lightweight various products, conventional cast-iron products are about to give way to light aluminum alloy products rapidly. For example, in the case of automobiles, it is possible to expect mileage improvement by lightweighting, and the lightweighting is effective in environmental improvement as well. By the way, high strength and high ductility have come to be required even for thin-thickness cast products (die-cast products especially), to which the requirements for strength and ductility have been moderate relatively. As a method for producing high-strength and high-ductility thin-thickness cast products, it has been proposed such a method that the resulting cast products are heat treated after casting while vacuuming the inside of dies, or after casting while filling the inside of dies with oxygen contrarily, for example. However, in such a method, heat treatments are needed to result in the increment of production costs. Moreover, the thinner and larger cast products are, the more the heat treatments cause strains of the cast products (swelling, deformations, and the like), and accordingly it takes more costs for the correction. Hence, in order to solve such problems, the development of aluminum alloys which reveal high strength and high ductility even as cast has been carried out extensively. For example, in {circle over (1)} Japanese Unexamined Patent Publication (KOKAI) No. 9-3582, {circle over (2)} Japanese Unexamined Patent Publication (KOKAI) No. 11-293375, {circle over (3)} Japanese Unexamined Patent Publication (KOKAI) No. 11-193434, and {circle over (4)} Japanese Unexamined Patent Publication (KOKAI) No. 9-268340, Japanese Unexamined Patent Publication (KOKAI) No. 9-316581 and Japanese Unexamined Patent Publication (KOKAI) No. 11-80872, and the like, there are disclosures on such aluminum alloys. Hereinafter, the aluminum alloys set forth in the respective publications will be described in detail. In {circle over (1)} Japanese Unexamined Patent Publication (KOKAI) No. 9-3582, an aluminum alloy cast product is disclosed which contains Mg: 3.0-5.5% (% by mass: being the same hereinafter), Zn: 1.0-2.0% (Mg/Zn: 1.5-5.5), Mn: 0.05-1.0%, Cu: 0.05-0.8%, and Fe: 0.1-0.8%. This Al—Mg-Mn—Zn—Cu system alloy contains Zn and Cu falling in a predetermined range as essential elements. When the present inventors tested and studied cast products made of this alloy, intermediate phases, such as MgZn 2 and Mg 32 (Al, Zn) 49 , are precipitated in the cast products, strength characteristic change by natural aging, and stress corrosion cracks appeared. Moreover, it was also understood that this alloy was such that hot tearing is likely to occur so that it was not suitable for casing thin-thickness members. In {circle over (2)} Japanese Unexamined Patent Publication (KOKAI) No. 11-293375, a highly ductile aluminum alloy die cast is disclosed which is characterized in that it comprises Mg: 2.5-7.0%, Mn: 0.2-1.0%, and Ti: 0.05-0.2%, and Fe in an amount of 0.3% and Si in an amount of 0.5% or less, a porosity is 0.5% or less at a heavy-thickness part ranging from 1 to 5 mm, the average circle-equivalent diameter of crystallized substances is 1.1 μm or less, and the areal ratio of crystallized substances is 5% or less. This Al—Mg—Mn—Ti system alloy is such that Fe is treated as an inevitable impurity and the content is limited to less than 0.3%. When the present inventors tested and studied thin-thickness die-cast products using this alloy, they were such that hot tearing was likely to occur. Moreover, when the Mg content increased, shrinkage cavities were likely to occur at the heavy-thickness center. The occurrence of hot tearing and shrinkage cavities is not preferable, because it enlarges the fluctuation of strength characteristic and elongation. In {circle over (3)} Japanese Unexamined Patent Publication (KOKAI) No. 11-193434, an aluminum alloy for high-toughness die-cast products is disclosed, aluminum alloy which comprises Mg: 3.0-5.5%, Mn: 1.5-2.0%, and Ni: 0.5-0.9%. In this Al—Mg-Mn—Ni system alloy, Ni is an essential constituent element, and the toughness of die-cast products are improved by adjusting the content appropriately. Moreover, since the Mn content is much, the crystallized amount of its compounds is so much that the elongation is 10% approximately as indicated by the examples. In {circle over (4)} (Japanese Unexamined Patent Publication (KOKAI) No. 9-268340, a highly ductile aluminum alloy is disclosed which comprises Mg: 0.01 to 1.2%, Mn: 0.5 to 2.5%; and Fe: 0.1-1.5%. In this Al—Mg—Mn—Fe system alloy, defects such as hot tearing and shrinkage cavities, are inhibited from occurring by decreasing the Mg content so as to merely improve the castability and elongation. Accordingly, it is seen from the examples as well that the alloys are not satisfactory in view of the strength because the tensile strength is even less than 190 MPa. Note that the aluminum alloys, disclosed in Japanese Unexamined Patent Publication (KOKAI) No. 9-316581 and Japanese Unexamined Patent Publication (KOKAI) No. 11-80872, are as poor as this alloy.

FIG. 2 is a cross-sectional view taken along the line “A-A” in FIG. 1 . FIG. 3 is a bar graph for illustrating the relationship between the constriction length and castability on each test sample. FIG. 4 is a graph for illustrating the relationship between the hot tearing characteristics and the Fe content. detailed-description description="Detailed Description" end="lead"?

<SOH> BACKGROUND ART <EOH>Conventionally, a hybrid electric vehicle that has an engine and an electric motor as the drive section comprises two types of battery, namely a high voltage battery for driving the electric motor, and an auxiliary low voltage battery for lamps and audio systems and the like. The batteries installed in the vehicle are constructed so that, taking maintenance into consideration, the batteries are charged by a motor generator installed in the vehicle. The construction of a conventional hybrid electric vehicle is shown in FIG. 16 . The reference numeral 8 indicates an engine and the reference numeral 9 indicates an electric motor, and power is transmitted from the engine or the electric motor, or from both the engine and the electric motor, to the tires via a power switching mechanism 10 . The electric motor 9 is controlled from a high voltage battery 70 , via a power conversion device 30 . The reference numeral 80 indicates an alternator, in a system configuration in which a low voltage battery 90 is charged by the rotation of the engine. The charging of the high voltage battery employs a setup in which the electric motor 9 operates as a generator, and charges the high voltage battery 70 via the power conversion device 30 . Furthermore, FIG. 17 is a structural diagram showing another conventional hybrid electric vehicle. The point of difference from the construction in FIG. 16 is that instead of being charged using the alternator 80 , the low voltage battery 90 is charged from the high voltage battery 70 via a DC-DC converter 100 (see “TOYOTA ESTIMA HYBRID new vehicle manual, product number 61994”, Toyota Motor Corporation Service Division, published June 2001, p0-9, p1-31). Moreover, regarding the motor generator, many motor generators with field winding systems have been proposed, including known motor generators which comprise two windings, namely a winding connected to the high voltage battery, and a winding connected to the low voltage battery (see Japanese Patent Laid-Open Publication No. Hei 6-105512, pages 1 and 3, FIG. 1). In a conventional electric vehicle drive system such as those described above, it is necessary to either provide two types of motor generator, for the main high voltage system and for the auxiliary low voltage system, or to provide one type of motor generator and a separate DC-DC converter. Accordingly, problems arise in that more mounting space is required, and in that the associated costs increase. If the motor generator is configured with a two winding field winding system, a problem occurs in that when winding the windings that are to provide power for the vehicle, the physical size of the motor generator becomes extremely large, and it cannot be installed in a vehicle. In addition, another problem arises in that because a field winding system is used, it is difficult to control the respective windings at the same time. Accordingly, an object of the present invention is to provide a compact and low cost electric vehicle drive system using a magnetic field system which integrates two types of motor generator.

<SOH> BACKGROUND TO THE INVENTION <EOH>Blasting operations frequently trigger a series of explosions in an exact order, with precise timing. For this purpose, blasting systems have been developed that employ shock tubes (also known as signal transmission lines) that transfer a blast initiation signal to an explosive charge. A signal from a single shock tube can be transferred to multiple shock tubes in a blasting system via the use of connector block/detonator assemblies, thereby permitting the initiation of multiple explosive charges in a controlled manner. Safety and reliability are paramount for any blasting system, and efficient shock tube initiation is an important factor in this regard. Shock tube initiation failure results in unexploded charges at the blast site, with inevitable safety concerns. Moreover, the reliable initiation of shock tubes ensures that the required blasting pattern is effected. The efficiency of shock tube initiation depends primarily upon connector block design. Reliable initiation of shock tubes requires sufficient energy to be transferred from the base charge of the detonator to the shock tubes, thereby compressing the shock tubes extremely rapidly to initiate them. The shock tube retention means of a connector block holds one or more shock tubes in contact with, or close proximity to, the percussion-actuation end of the detonator retained within the block. Importantly, the shock tube retention means ensures that the shock tubes are retained in signal transmission relationship with the detonator. Several examples of connector block designs are known in the art, which comprise a shock tube retention means for the arrangement of at least one shock tube adjacent to the percussion-actuation end of the detonator. These examples generally encompass the use of a clip-like member, integral with the connector block, for retaining the shock tubes within a slot formed between the clip-like member and the percussion-actuation end of the detonator. In this way, the shock tubes are retained in signal transmission relationship with the end of the detonator. In one example, U.S. Pat. No. 5,204,492, issued to ICI Explosives USA Inc. on Apr. 20, 1993, discloses a detonator assembly for initiating up to eight transmission lines. The assembly comprises a connector block that houses a low strength detonator. The connector block comprises a confining wall surrounding the closed end of the low strength detonator. One or more signal transmission lines can be inserted through a gap in the confining wall and operatively confined adjacent to the percussion-actuation (closed) end of the low strength detonator. Corresponding U.S. Pat. Nos. 5,171,935 and 5,398,611, issued to the Ensign Bickford Company on Dec. 15, 1992 and Mar. 21, 1995 respectively, disclose a connector block having a housing with a channel formed therein for receiving a low energy detonator. The connector block further comprises a tube engaging member for holding transmission tubes adjacent an end of the channel, wherein the tube engaging member is attached to the connector block via a resiliently deformable segment. Transmission tubes may be inserted into a slot formed between the housing and the tube engaging member. In another example, U.S. Pat. No. 5,703,319, issued to the Ensign Bickford Company on Dec. 30, 1997, discloses a connector block comprising a clip member. The clip member cooperates with the signal transmission end of a body member to define a slot for receiving one or more signal transmission lines in communication with the output end of a detonator. The clip member is characterized in that it comprises a section of continuously decreasing thickness to facilitate lateral insertion of signal transmission lines into the slot by deformation of the clip member. U.S. Pat. No. 5,499,581 issued to the Ensign-Bickford Company on Mar. 19, 1996, discloses a connector block design for connecting signal transmission lines in a blasting system. The patent discloses improved means for securing a detonator within the connector block via a displaceable locking member. The connector block may further comprise a flexible, cantilevered line retaining means to receive one or a plurality of outgoing signal transmission lines. In a final example, U.S. Pat. No. 5,659,149 issued to the Ensign-Bickford Company on Aug. 19, 1997, discloses a connector block including a slot configured to constrain just a single acceptor line retained therein in an undulate configuration i.e. a configuration having consecutive (multiple) bends or kinks including zig-zags. In this way the acceptor line is retained more securely within the slot by virtue of the multiple contortions introduced into the acceptor line, thereby preventing unwanted sliding or displacement of the connector block along the acceptor line. The connector blocks disclosed by the prior art generally retain at least one shock tube in signal transmission relationship with the percussion-actuation end of a detonator by confining the shock tube(s) within a slot. Preferably, the slot is dimensioned to retain the shock tubes in signal transmission relationship with the detonator, without unduly squeezing the shock tubes. In this way, the energy of detonator actuation compresses the shock tubes extremely rapidly, thereby resulting in their initiation. The inventor of the present application has determined that optimal energy transfer requires contact between the shock tubes and the surface of the percussion-actuation end of the detonator (or the surface of a positioning surface, which is in contact with the detonator). However, the inventor has noted that dimensional tolerances in the manufacture of connector blocks and shock tubes can result in poor shock tube/detonator contact. For this reason, the insertion of an undersized shock tube into an oversized slot of a connector block can result in poor shock tube/detonator contact, and reduced transfer efficiency of actuation energy. Therefore, manufacturing tolerances can contribute significantly to shock tube initiation reliability. Furthermore, an undersized shock tube in an oversized slot would allow the block to slide uncontrollably to other undesirable locations along the shock tube. In addition, plastic connector blocks comprising flexible shock tube retention means can exhibit variations in slot dimensions. The connector blocks of the prior art generally comprise flexible and resilient shock tube retention means in the form of a clip, for holding the shock tubes in signal transmission relationship with the percussion-actuation end of a detonator. The flexibility of the shock tube retention means can permit facile shock tube insertion. However, the inventor of the present application has determined that shock tube retention means of this kind may not properly reassume their original shape after distortion, thereby affecting the width of the shock tube retention slot. Moreover, the presence of one or more shock tubes within the slot can alter the configuration of the shock tube retention means, thereby affecting slot width for subsequent shock tube insertion. These factors may further increase the risk of improper shock tube detonator contact within the connector block. Accordingly, there is a need for improved connector block designs, wherein shock tubes are positioned in efficient signal transmission relationship with the percussion-actuation end of a detonator, and preferably in material contact with the detonator.
<SOH> SUMMARY OF THE INVENTION <EOH>An object of the present invention, at least in a preferred form thereof, is to provide a connector block, wherein shock tubes are preferably retained in firm contact with the percussion-actuation end of a detonator. In this way, air gaps between the detonator and the shock tubes are essentially eliminated, thereby increasing the energy transfer efficiency from the detonator to the shock tubes. It is a further object of the present invention, at least in a preferred form thereof, to provide a connector block wherein shock tubes are positioned accurately in signal transmission relationship with the percussion-actuation end of a detonator, wherein air gaps resulting from manufacturing tolerances are virtually eliminated. It is a further object of the present invention, at least in a preferred form thereof, to provide a connector block, wherein the connector block is substantially prevented from sliding along the shock tubes located within the slot of the connector block. Conventional connector block designs include a ‘straight’ slot for the retention of shock tubes. As will be apparent from the foregoing, a straight slot presents significant disadvantages with regard to the security of shock tube retention, and the possibility of the connector block being slidably displaced along the tubes. Moreover, previous attempts to address these issues have lead to the generation of connector blocks configured to constrain shock tubes in a contorted undulate configuration within the block, in which multiple bends or kinks are introduced into the shock tube(s) (see U.S. Pat. No. 5,659,149). However, the inventors have found that such contortions render the shock tubes difficult to insert into the connector blocks, and can present difficulties with maintaining optimal signal transmission. The inventors unexpectedly found that the connector blocks of the present invention, in which a single principle bend is introduced into the shock tube(s) allows for optimization of multiple connector block attributes. The connector blocks disclosed herein permit relatively facile shock tube insertion, excellent detonator-to-shock tube signal transfer efficiency, secure retention of shock tubes, and uptake of unwanted tolerances in connector block or shock tube manufacture. Moreover, unlike the connector block designs disclosed in U.S. Pat. No. 5,659,149, the connector block of the present invention permit insertion of a plurality of shock tubes. Therefore, in a first embodiment there is provided a connector block for retaining at least one shock tube in signal transfer relationship with a detonator, the connector block comprising: a housing having a bore formed therein for receiving a detonator provided with a percussion-actuation end; and a shock tube retention means defining with the housing a slot for receiving therein at least one shock tube and holding the shock tube(s) in signal transfer relationship with the percussion-actuation end of the detonator present in the bore, the slot having an entrance for allowing insertion of the shock tube(s) into the bore, characterized in that at least one of the housing and the shock tube retention means adjacent to the slot is configured to induce a bend in the shock tube(s) passing through the slot. In an alternative embodiment, there is provided a connector block for retaining at least one shock tube in signal transfer relationship with a detonator, the connector block comprising: a housing having a bore formed therein for receiving a detonator provided with a percussion-actuation end; and a shock tube retention means defining with said housing a slot for receiving therein at least one shock tube and holding the shock tube(s) in signal transfer relationship with the percussion-actuation end of the detonator present in the bore, the slot having an entrance for allowing insertion of the shock tube(s) into the slot, characterized in that at least one of the housing and the shock tube retention means includes at least one projection facing the slot, which projection causes the shock tube(s) positioned in the slot to bend in a region passing through the slot. The invention also relates to a detonator assembly comprising a connector block as defined above, a detonator positioned within the bore of the connector block housing and at least one shock tube retained within the slot of the connector block. Preferably, the connector blocks of the present invention induce the shock tubes to contact the percussion-actuation end of the detonator. In an alternative embodiment, the connector blocks of the present invention further comprise a positioning membrane for positioning the surface of the percussion-actuation end of the detonator in signal transmission relationship with the slot. In this way, the slot may be defined in part by the positioning membrane. The corresponding connector blocks are preferably configured to ensure the shock tubes contact the positioning surface, which contacts the percussion-actuation end of the detonator. The positioning membrane may partially or completely enclose the signal transmission end of the bore. In an alternative embodiment of the present invention, at least one of the housing or the shock tube retention means comprise two projections configured to induce a bend in the shock tube or shock tubes deposited within the slot of the connector block. Preferably, the connector blocks of the present invention are suitable for housing a detonator with a hemispherical percussion-actuation end. In this way, the shock tubes may be arranged and retained within the slot equidistant from the initiation point of the hemispherical base charge within the percussion-actuation end of the detonator. In one embodiment, the shock tubes may be bent towards the percussion-actuation end of the detonator. In an alternative embodiment, the shock tubes may be bent away from the percussion-actuation end of the detonator. The present invention encompasses connector blocks that induce one or more shock tubes positioned therein, to bend either towards or away from the detonator, whilst preferably contacting the percussion-actuation end of the detonator (or a positioning membrane in contact with the percussion-actuation end of the detonator). The connector block configuration of the present invention induces a single principle bend (preferably a shallow arcuate curve) in one or several shock tubes as they pass within the slot, to improve the signal transmission and/or contact of the detonator with the shock tube(s). Advantageously, the present invention makes it possible to retain a plurality of shock tubes in signal transmission relationship with a detonator.

<SOH> BACKGROUND TO THE INVENTION <EOH>Blasting operations frequently trigger a series of explosions in an exact order, with precise timing. For this purpose, blasting systems have been developed that employ shock tubes (also known as signal transmission lines) that transfer a blast initiation signal to an explosive charge. A signal from a single shock tube can be transferred to multiple shock tubes in a blasting system via the use of connector block/detonator assemblies, thereby permitting the initiation of multiple explosive charges in a controlled manner. Safety and reliability are paramount for any blasting system, and efficient shock tube initiation is an important factor in this regard. Shock tubes that fail to initiate result in unexploded charges at the blast site, with inevitable safety concerns. Moreover, the reliable initiation of shock tubes is imperative to ensure that the required blasting pattern is effected. The efficiency of shock tube initiation is dependent primarily upon connector block design. Reliable initiation of shock tubes requires the transfer of sufficient energy from the base charge of the detonator to the shock tubes, thereby compressing the shock tubes rapidly with sufficient energy and speed to initiate them. The shock tube retention means of a connector block holds one or more shock tubes in contact with, or close proximity to, the percussion-actuation end of the detonator retained within the block. Importantly, the shock tube retention means ensures that the shock tubes are retained in signal transmission relationship with the detonator. Several examples of connector block designs are known in the art, which comprise a shock tube retention means for holding at least one shock tube adjacent to the percussion-actuation end of the detonator.

In this way, the shock tubes are retained in signal transmission relationship with the end of the detonator. In one example, U.S. Pat. No. 5,204,492, issued to ICI Explosives USA Inc. on Apr. 20, 1993, discloses a detonator assembly for initiating up to eight transmission lines. The assembly comprises a connector block that houses a low strength detonator by means of a confining wall surrounding the closed end of the low strength detonator. One or more signal transmission lines can be inserted through a gap in the confining wall and operatively confined adjacent to the closed end of the low strength detonator. U.S. Pat. Nos. 5,171,935 and 5,398,611, issued to the Ensign Bickford Company on Dec. 15, 1992 and Mar. 21, 1995 respectively, disclose a connector block having a housing with a channel formed therein for receiving a low energy detonator. The connector block further comprises a shock tube engaging member for holding shock tubes (referred to as transmission tubes) adjacent an end of the channel, wherein the tube engaging member is attached to the connector block via a resiliently deformable segment. Shock tubes may be inserted into a slot formed between the housing and the tube engaging member. U.S. Pat. No. 5,499,581 issued to the Ensign-Bickford Company on Mar. 19, 1996, discloses a connector block design for connecting signal transmission lines in a blasting system. The patent discloses improved means for securing a detonator within the connector block via a displaceable locking member. The connector block may further comprise a flexible, cantilevered line retaining means to receive one or a plurality of outgoing signal transmission lines. In another example, U.S. Pat. No. 5,703,319, issued to the Ensign Bickford Company on Dec. 30, 1997, discloses a connector block comprising a clip member. The clip member cooperates with the signal transmission end of a body member to define a slot for receiving one or more signal transmission lines in communication with the output end of a detonator. The clip member is characterised in that it comprises a section of continuously reducing thickness to facilitate lateral insertion of signal transmission lines into the slot by deformation of the clip member. In another example, U.S. Pat. No. 5,659,149 issued to the Ensign Bickford Company on Aug. 19, 1997 discloses connector blocks comprising a slot for retaining a single acceptor line in an undulate configuration therein (i.e. the single acceptor line is contorted to have multiple bends or links). In a preferred embodiment, the connector blocks may further include a moveable retainer member located on a side of the slot opposite the detonator end. The moveable retainer member is generally integral with the shock tube retention means, and includes a barb for retaining the single acceptor line in position adjacent the end of a detonator. In a final example, the so called Handidet™X405 provides for a connector block for retaining shock tubes in signal transmission relationship with the percussion-actuation end of a detonator. The shock tubes are retained in a slot defined between a flexible shock tube retention means and the adjacent housing of the connector block. The entrance to the slot is formed between a semi-rigid member integral with the housing, and a flexible tip integral with the flexible shock tube retention means. Shock tubes may be inserted through the entrance of the slot by deformation of the flexible shock tube retention means (and, in particular, the flexible tip), and the semi-rigid member integral with the housing. Importantly, the access to the slot depends primarily upon the flexibility of the shock tube retention means and the flexible tip. Although the semi-rigid member exhibits a limited degree of flexibility, the principle function of this member is to retain the shock tubes within the connector block once inserted into the slot. The connector blocks disclosed in the prior art generally comprise shock tube retention means comprising a material with a significant degree of resilient flexibility. The flexibility of the shock tube retention means permits facile insertion of the shock tubes between the shock tube retention means and the percussion-actuation end of a detonator housed within the block. For this purpose, the shock tube retention means comprises a member that can be temporarily deformed by application of force by the user, thereby allowing access to a slot (or equivalent thereof) for insertion of the shock tubes therein. Release of the force permits the shock tube retention means to assume its original configuration, and retain the shock tubes in the slot. A variation on this theme is provided by U.S. Pat. No. 5,659,149 (as previously described), in which a single acceptor line is retained by a resilient barbed member generally integral with the shock tube retention means. Nonetheless, the configuration of the disclosed connector blocks is such that only a single line may be retained, and the shock tube retention means comprises complex components that reduce the integrity of the connector block upon detonator initiation, thereby increasing the quantity of shrapnel.
<SOH> SUMMARY OF THE INVENTION <EOH>The inventors of the present application have encountered significant problems with the connector blocks of the prior art that include flexible or insubstantial shock tube retention means. Firstly, shock tube retention means that are at least partly flexible exhibit a measurable degree of residual plastic deformation. Consequently, such shock tube retention means sometimes fail to retain shock tubes with sufficient precision of placement adjacent the percussion actuation end of a detonator. Secondly, the shock tubes may be retained with insufficient friction, thereby resulting in the connector block sliding along the length of the shock tubes retained therein. Thirdly, connector blocks comprising at least partially flexible shock tube retention means can exhibit reduced integrity upon detonator actuation causing increased shrapnel. The present invention, at least in preferred forms, aims to provide a connector block for accurate positioning of shock tubes in signal transmission relationship with the percussion-actuation end of a detonator, wherein the connector block prevents inadvertent removal of the shock tubes. A further object of the present invention, at least in preferred forms, is to provide a connector block that does not normally fragment upon actuation of a detonator housed therein. In this way, the quantity of shrapnel is reduced. A further object of the present invention, at least in preferred forms, is to provide a connector block wherein the force required to insert a shock tube into the connector block is suitable for facile manual operation, yet once inserted the shock tube is securely retained. A further object of the present invention, at least in preferred forms, is to provide a connector block for retaining shock tubes in accurate energy communicating relationship with the percussion-actuation end of a detonator. A connector block for retaining at least one shock tube in signal transfer relationship with a detonator, the connector block comprising: a housing having a bore formed therein for receiving a detonator provided with a percussion-actuation end and a base charge disposed within the percussion-actuation end, the bore having an insertion end for receiving the detonator and a signal transmission end for positioning the percussion-actuation end of the detonator in signal transfer relationship with said at least one shock tube; a shock tube retention means integral with the housing and extending to project over the signal transmission end of said bore, to define with the housing a slot for receiving therein at least one shock tube, and to hold said at least one shock tube in signal transfer relationship with said percussion-actuation end of said detonator present in said bore, said slot having an entrance for allowing insertion of each shock tube into said slot; and a flexible and resilient closure member integral with the housing and extending partially or fully into said entrance; wherein said shock tube retention means has limited flexibility, and said closure member resiliently flexes away from said entrance to allow entry of each shock tube through said entrance and into said slot, said closure member flexing through a distance at least 60%, preferably at least 90%, of the diameter of the shock tube(s). Most preferably, the shock tube retention means is so rigid that it undergoes little or no flexing when a shock tube is inserted into the slot. Ideally, the shock tube retention means is so rigid and so firmly attached to the housing that it remains in place following actuation of the detonator. Preferably, the connector block comprises a substantially uniform material throughout, and differences in the relative thickness of the material comprising the shock tube retention means and the flexible and resilient closure member cause the relative flexibility of the closure member and the relatively inflexibility of the shock tube retention means necessary for the difference in flexibility mentioned above. Preferably, a shock tube may be inserted into the slot with a force of about 45 Newtons (about 10 pounds force) or less. In an alternative aspect of the present invention, there is provided a connector block for retaining at least one shock tube in signal transfer relationship with a detonator, wherein the connector block comprises: a housing having a bore formed therein for receiving a detonator provided with a percussion-actuation end and a base charge disposed within the percussion-actuation end, the bore having an insertion end for receiving the detonator and a signal transmission end for positioning the percussion-actuation end of the detonator in signal transfer relationship with said at least one shock tube; a substantially rigid shock tube retention means integral with the housing and extending to project over the signal transmission end of said bore, to define with said housing a slot for receiving therein at least one shock tube and holding said at least one shock tube in signal transfer relationship with said percussion-actuation end of said detonator present in said bore, said slot having an entrance for allowing insertion of said at least one shock tube into said slot; and a closure member extending partially or fully into said entrance and attached to said housing via a sprung hinge, said closure member being arranged relative to said entrance to allow entry of said at least one shock tube into said slot by movement of said closure member about said sprung hinge against a bias. In accordance with the present invention, at least in a preferred form, the combined use of a shock tube retention means of limited flexibility, together with a flexible and resilient closure member permits significantly easier shock tube insertion, accurate shock tube positioning, and secure shock tube retention. Moreover, the limited flexibility of the shock tube retention means is expected to improve the resilience of the connector block to fragmentation upon detonator actuation, thereby reducing the amount of shrapnel generated. Preferably, the closure member extends partially or fully into the entrance of the slot at an angle of from about 45° to about 135° relative to the longitudinal axis of the bore. More preferably, the closure member extends partially or fully into the entrance of the slot at an angle of from about 45° to about 90° relative to the longitudinal axis of the bore. In this way, the closure member is configured to avoid interference with the housing upon flexing of the closure member away from the entrance to the slot. The connector blocks of the present invention may further comprise a shock tube insertion guide integral with the shock tube retention means, the shock tube insertion guide defining with the closure member a receiving space for guiding shock tubes to the entrance of the slot. Preferably, the receiving space narrows at an end adjacent the opening of said slot, thereby facilitating insertion of the shock tubes into the slot.

<SOH> BACKGROUND OF THE INVENTION <EOH>In commercial blasting operations, a series of explosions is frequently triggered in an exact order with precise timing. For this purpose, blasting systems have been developed that employ shock tubes also known as signal transmission lines that transfer a blast initiation signal to a series of explosive charges. To facilitate this, a signal from a single shock tube can be transferred to multiple shock tubes in a blasting system via the use of connector block/detonator assemblies, thereby permitting the initiation of multiple explosive charges in a controlled manner. Safety and reliability are paramount for any blasting system, and efficient shock tube initiation is an important factor in this regard. Shock tubes that fail to initiate result in unexploded charges at the blast site, with inevitable safety concerns. Moreover, the reliable initiation of shock tubes is imperative to ensure the required blasting pattern is effected. The design of the connector block has a significant influence upon the efficiency of shock tube initiation. For reliable initiation, sufficient energy must be transferred from the base charge of a detonator to the shock tubes, thus compressing the shock tubes extremely rapidly in order to initiate them. Several connector block designs are known in the art, which have been developed to improve the efficiency of energy transfer from the base charge of the detonator to the shock tubes. The most efficient transfer of energy from the detonator base charge to the shock tubes occurs when the surface of the percussion-actuation end of the detonator is in direct contact with the shock tubes. If any gap is present between the detonator end and the shock tubes, the transfer of actuation energy may be less efficient, thus resulting in an increased failure rate of shock tube initiation. However, excess pressure from the percussion-actuation end of the detonator upon the shock tubes can result in the distortion of the shock tubes, and consequently the reduction of shock tube internal volume within the connector block. This in turn reduces the capacity of the shock tubes for efficient initiation, since their capacity for rapid compression is also reduced. Connector blocks and their components are generally manufactured by plastic molding techniques that are well understood in the art. Quality control during the manufacturing process can ensure a degree of uniformity in the dimensions and mechanical properties of the connector blocks produced. However, slight differences between connector blocks are unavoidable due to tolerances in the plastic resulting from both the manufacturing process, and from the properties of the plastic material. Slight differences may also occur in the dimensions of the detonator. Such tolerances can give rise to improper positioning of the detonator within the connector block, relative to the shock tubes. For example, upon actuation of the detonator, a slight gap between some of the shock tubes and the percussion-actuation end can result in a reduction in energy transfer to the shock tubes. Therefore, it is desirable to design a connector block wherein the detonator can be securely and optimally positioned to contact but not squeeze the shock tubes within the block. Previously, several attempts have been made to design connector blocks with improved reliability of shock tube initiation. However, it is important to note that previous designs generally involve the use of detonator retention means such as clips, latches, and collar locks to secure the detonator within the block. Typically, such detonator retention means employ elements that are integrally molded into the plastic of the block, or molded as a separate component. For this reason, the position of the detonator within the block is specifically governed by the position of the retention means, which locks the detonator into a fixed position relative to the shock tubes. Therefore, the distance between the retention means and the shock tubes is fixed at the point of manufacture of the connector block, and no allowance is subsequently made for tolerances in the plastic material of the block or the dimensions of the detonator. In one example of such a device, U.S. Pat. No. 4,815,382 issued Mar. 28, 1989, discloses a connector block comprising a plastic tube having a bore, with at least one transverse bore arranged perpendicular to the main bore. The main bore is designed to receive a detonator shell, and the transverse bores can receive a length of shock tube. The detonator shell may be fixed within the connector block by means of a circumferential lip on the inside wall of the main bore, which engages a circumferential crimp at the percussion-actuation end of the detonator shell. In this way, the detonator is secured within the plastic housing of the connector block. In another example, corresponding U.S. Pat. Nos. 5,171,935 and 5,398,611 issued Dec. 15, 1992 and Mar. 21, 1995 respectively, disclose a detonator block with a positioning means on the housing of the block, for positioning the detonator in juxtaposed signal transfer relationship with one or more shock tubes. In certain embodiments of the invention, there are also provided deformable tabs within the housing for snap-fit retention of the detonator within the connector block. Subsequent improvements in connector block design lead to the use of collar locks for detonator retention. For example, U.S. Pat. No. 5,423,263, issued Jun. 13, 1995, discloses a connector block designed for transfer of explosive energy from the detonator for bi-directional initiation of shock tubes. In a preferred embodiment, the detonator may be held in the connector block by a collar lock device that secures the detonator at the closure crimp, present at the end of the detonator opposite the percussion-actuation end. The collar lock is slidably mounted within a groove in the block that runs perpendicular to the longitudinal axis of the detonator. An alternative design of connector block is disclosed by U.S. Pat. No. 5,499,581, issued Mar. 19, 1996, which comprises an integral slidably mounted locking member. Once the detonator is inserted into the connector block, the locking member is displaced to rupture a frangible web and engage the closure crimp of the detonator. Moreover, the displaced locking member itself becomes locked into the displaced position by engaging the connector block. In an alternative embodiment, various shapes for the locking member are disclosed, each to secure the detonator in a fixed position relative to the shock tubes, and ensure irreversible engagement of the locking member in the displaced position. An apparent modification to U.S. Pat. No. 5,499,581 is disclosed by U.S. Pat. No. 5,792,975, issued Aug. 11, 1998. In this regard, a similar connector block is provided comprising a slidably mounted locking member. The patent discloses an improvement in the configuration of the locking member, wherein the member comprises at least one wedge-shaped surface, so that upon displacement of the locking member towards its locking position, the wedge-shaped surface moves the detonator axially into position, adjacent to the shock tubes. In this way, the position of the detonator is biased towards the shock tubes. As will be apparent from the discussion above, the connector blocks of the prior art frequently include complex design features to lock the detonator in a desired position. Moreover, the corresponding manufacturing processes may require several molds to produce the multiple components for the block, followed by the precise assembly of the components. It is undesirable to produce complex connector blocks for several reasons. Design complexity, and the need for multiple manufacturing steps, can result in a reduction in the quality and reliability of the connector blocks. In addition, production costs also increase with design complexity. For practical use at the detonation site, connector blocks must be robust, reliable, and not prone to failure. The inclusion of intricate features in connector block design such as slidably mounted locking members can be detrimental to ease of handling in the field, as well as the functionality and the robustness of the blocks. There is therefore a need for connector blocks of improved design and improved methods of manufacture of such blocks.

In this way, the present invention allows a detonator to be secured within a connector block without the need for clips, latches and similar retention devices. The term “bore” as used herein means either a hole (preferably, but not necessarily, cylindrical) running though the interior of the connector block of the present invention, or alternatively an open channel or groove formed in a side of the connector block, for the housing of a detonator therein. The connector block of the present invention may further comprise a membrane having positioning membrane located within the bore adjacent to the signal transmission end, for accurately positioning the percussion-actuation end of the detonator in signal transfer relationship with the shock tubes located in the slot. In this manner, the present invention allows a detonator to be secured within a connector block in a position that is optimal for energy transfer from the percussion-actuation end of the detonator to the shock tubes. Importantly, any incorrect positioning of the percussion-actuation end of the detonator, resulting from any divergence in the dimensions of the connector block or detonator due to tolerance, will preferably be virtually eliminated. In this way, the present invention discloses, in one embodiment, a method for the assembly of a detonator within a connector block, so that the percussion-actuation end of the detonator abuts the positioning membrane of a membrane within the bore, and is thereby optimally positioned for efficient energy transfer from the detonator base charge to the shock tubes. Therefore, the invention provides a method of producing a detonator connector block assembly, wherein the detonator is optimally positioned for actuation of shock tubes, regardless of the tolerance in the connector block or detonator.

<SOH> BACKGROUND <EOH>1. Field Embodiments of the present invention relate to arrangements for compensation of a magnetic bias field in a storage layer of a magnetoresistive memory cell provided in a semiconductor device. In addition, the invention relates to methods for compensation of such a bias field. 2. Background A memory cell based on the magnetoresistance effect conventionally has been realized by a stack of two thin ferromagnetic layers, with an intervening nonferromagnetic isolating layer having a thickness of a plurality of atomic layers. One of the two ferromagnetic layers is composed of a hard-magnetic material, typically a cobalt-iron alloy. With a magnetization which is constant in terms of magnitude and direction, it functions as a reference layer. The second ferromagnetic layer made of a soft-magnetic material, typically a nickel-iron alloy, forming a storage layer. Its magnetization is oriented unidirectionally, or in oppositely directed fashion with respect to the magnetization of the reference layer, corresponding to data content of the memory cell. When a unit of data is written to the memory cell, the direction of a write current in an address line of the memory cell determines the orientation of the magnetization in the storage layer with respect to the magnetization of the reference layer. The material of the isolating layer is a dielectric in the case of a memory cell configuration based on a tunneling effect (MTJ, magnetic tunnel junction). In this case, the effect underlying the read-out of the memory cell is that the frequency of electrons crossing through the isolating layer (tunnel barrier) is higher in the case of identical orientation of the magnetization of the two ferromagnetic layers than in the case of opposite orientation. The effect underlying the read-out of the memory cell is thus based on internal properties of the magnetized ferromagnetic layers, but not on a direct interaction of the magnetic fields generated by the two layers. Their interaction, or ferro- and antiferromagnetic coupling, influences the operating behavior of the memory cell. In this case, the term “ferromagnetic coupling” denotes that proportion of the interaction that promotes an orientation of the magnetization of the storage layer parallel to the orientation of the magnetization of the reference layer and inhibits a changeover of the magnetization of the storage layer in a direction opposite to the magnetization of the reference layer. The term “antiferromagnetic coupling” denotes that proportion of the interaction that inhibits a storage layer orientation parallel to the orientation of the magnetization of the reference layer and promotes a changeover of the magnetization direction of the storage layer in a direction opposite to the magnetization direction of the reference layer. The ferro- and antiferromagnetic couplings between the reference layer and storage layer of one and the same memory cell, but also of adjacent memory cells, make contributions to a magnetic bias field within and outside a semiconductor device having magnetoresistive memory cells. In a storage layer permeated by such a bias field, the bias field effects a shift in the field strengths required for changing over the magnetization direction, the so-called coercive field strengths. This shift requires an asymmetry in the magnetic fields required for writing and thus also in the write currents. This effect is illustrated by the two illustrations in FIG. 2 , which is reduced to a one-dimensional changeover of the storage layer for simplification. In this case, H C1 and H C2 designate magnitudes of coercive field strengths required for changing over the magnetization between the states M 0 and M 1 in the absence of a bias field, and H B denotes the magnitude of the magnetic bias field. The upper part of FIG. 2 illustrates the magnetization reversal curve of a storage layer for the case of an absent bias field. The specific coercive field strengths H C1 and −H C1 are symmetrical with respect to the magnetization axis. The lower part of FIG. 2 illustrates a magnetization curve relative to a magnetic field H(I) generated by the write current I in the case of superposition with a bias field acting oppositely to the magnetic field axis. For such a magnetic field, the magnetization curve appears to be shifted by the magnitude H B counter to the direction of H B . If the bias field and the magnetization of the storage layer are unidirectional, then a changeover of the magnetization requires a magnetic field whose magnitude results from the sum of the specific coercive field strength of the storage layer and the magnetic field strength of the bias field. In this case, the bias field, given a predetermined maximum write current, reduces reserves with regard to a reliable changeover of the magnetization in the storage layer of the memory cell. If the bias field is directed oppositely to the magnetization of the storage layer, then a magnetic field having a magnitude corresponding to the magnitude of the specific coercive field strength of the storage layer reduced by the magnitude of the magnetic field strength of the bias field already suffices for changing over the magnetization. In this case, even smaller magnetic fields may compel a changeover of the magnetization. A reserve with respect to an undesired changeover of the magnetization is thus reduced. Such magnetic fields may be caused on the one hand by extreme interference fields with a source outside the semiconductor device. A second source of such magnetic fields is, for instance, magnetic fields generated by write currents of adjacent memory cells within the semiconductor device. The ferromagnetic coupling which underlies the bias field in the storage layer is determined by the distance between the two ferromagnetic layers, the thickness of the storage layer, and also the roughness of the layers forming the memory cell. In this respect, reference is made to L. Néel, Comptes Rendus Acad. Sci. 255, 1676 (1962) and, in particular, formula (1) in A. Anguelouch et al., Two-dimensional magnetic switching of micron-size films in magnetic tunnel junctions, Applied Physics Letters, Vol. 76, No. 5, 2000. In this case, the orientation of the bias field is not necessarily effected in a direction parallel to the orientation of the magnetic fields generated by the write currents, but rather may also have a component which is orthogonal thereto and parallel to the storage layer. In this respect, reference is made in particular to FIG. 2 a in A. Anguelouch et al., Two-dimensional magnetic switching of micron-size films in magnetic tunnel junctions, Applied Physics Letters, Vol. 76, No. 5, 2000. The physical causes of this effect are not completely known, but the bias field does not change in terms of magnitude and direction during a lifetime of the memory cell. In particular, the roughness of the layers yields variable and at the same time difficult-to-predict proportions with respect to the bias field. In this case, the roughness contribution varies between semiconductor devices, even of identical designs, which are produced from different wafers, while it is similar in the case of semiconductor devices which are produced from the same wafer. FIG. 3 illustrates a diagrammatic cross section through a magnetoresistive memory cell. An isolating layer 2 lies between a reference layer 3 and a storage layer 1 . Dividing the reference layer 3 into a lower and an upper reference sublayer 3 a , 3 c with a nonmagnetic intermediate layer 3 b produces a magnetic leakage field, which may produce an antiferromagnetic coupling indicated by the arrow 5 . The causes of the ferromagnetic coupling, that is to say the roughness of the layers, and also the thickness of isolating layer and storage layer, are indicated by the arrow 4 . In order to reduce the bias field, at the present time attempts are being made, on the one hand, to reduce the ferromagnetic coupling. On the other hand, attempts are being made to set the antiferromagnetic coupling toward a compensation of the bias field. A reduction of the ferromagnetic coupling by using a thicker storage layer is confronted with the obstacle of the larger switching currents which are then necessary for changing over the magnetization. Equally, the distance between the ferromagnetic layers is prescribed by the requirements made of the electrical resistance of the memory cell and by thermodynamic requirements. Limits are imposed on compensation by means of the antiferromagnetic coupling since the latter exhibits a stable behavior only given low net moment. For a maximum effect, one of the reference sublayers would have to be dispensed with, as a result of which the stability of the reference layer would also be impaired. Furthermore, it cannot be used to effect compensation of a ferromagnetic coupling which is brought about for instance as a result of magnetorestriction during a patterning operation of the memory cell or the semiconductor device and is rotated with respect to the magnetization direction of the storage layer. Furthermore, the antiferromagnetic coupling is unsuitable, in the case of semiconductor devices produced from different wafers, for compensating for contributions of the ferromagnetic coupling—brought about by the roughness of the layers—which regularly deviate from one another.

<SOH> BACKGROUND <EOH>1. Field The present invention relates to a process for depositing silicon nitride on an exposed substrate. 2. Background Silicon nitride has long been in widespread use in semiconductor technology. Two primary applications for silicon nitride in this context are for forming diffusion barriers, even to very small molecules such as hydrogen molecules, and for use as a mask in etching processes, on account of its etching selectivity with respect to silicon dioxide. Silicon nitride usually is deposited on a substrate by the substrate being exposed, in a furnace, to a flow which substantially contains nitrogen and silicon, with simultaneous heating. It is typical to maintain temperatures of well over 700° C. in the furnace. On account of these high temperatures, the heat budget for the production or deposition of silicon nitride layers is relatively great. In this context, the term “heat budget” is to be understood as meaning the integral of the heat quantity over time. Further description in this regard is provided in U.S. Pat. No. 5,629,043. Another problem associated with the use of silicon nitride is the high thermal budget caused by the high deposition temperature. A high thermal budget of this nature is undesirable in the development of many new types of semiconductor modules, since it can damage or destroy the results of preceding steps which already have been carried out. For the abovementioned reasons, for some time there has been an ongoing search for new types of materials that allow the heat budget to be reduced while maintaining the other advantages associated with silicon nitride. Suitable candidates for materials of this type include RTCVD nitrides (RT=Rapid Thermal; CVD=Chemical Vapor Deposition). However, these materials are extremely expensive on account of high production and storage costs. Other materials that have been considered are based on new types of precursors, such as BTBAS (BTBAS=Bis-tertiary-butylamino-silane). Although a precursor of this nature can be used in a furnace process, like the RTCVD nitrides it is extremely expensive. Problem to be solved.
<SOH> SUMMARY <EOH>A process is disclosed for depositing silicon nitride that can be carried out in a simplified manner, and in which the silicon nitride is permeable to small molecules, such as hydrogen, without losing its etching selectivity with respect in particular to silicon nitride. As an exemplary embodiment of the invention, a method is described for depositing silicon nitride on a silicon substrate in which the silicon substrate is exposed, in a furnace and under the action of heat. A step is provided for setting a temperature in the furnace to approximately 600° C. to 645° C. A step is also provided for providing a flow comprising a silicon component and a nitrogen component. As further embodiments, the silicon component is selected as dichlorosilane, or the nitrogen component is selected as ammonia. Embodiments and aspects of the invention are explained in further detail below with reference to a drawing that diagrammatically depicts a silicon nitride furnace.

<SOH> BACKGROUND OF THE INVENTION <EOH>A wide variety of information about a vehicle, its performance, maintenance, orientation, and the condition of its numerous systems (fuel, door closure, temperature) and the like have been collected and displayed within vehicle interiors for many years. In recent years, with technology developments accelerating at heretofore unbelievable rates, the types of information collected, the accuracy thereof and the methods for displaying the information have also been increasing. Examples include compass and mirror technology and the combination thereof, where compass headings are displayed on the surface of the vehicle interior. These various examples of information collection and/or display are provided purely for purposes of establishing a general background from which the display improvement of the present invention can be appreciated. At present, the displays themselves, wherever they have been located, involve hardware and systems which are typically designed for specific applications for reasons of size, attachment, supplying power thereto or the like. Little flexibility currently exists for using conformable display surfaces in a variety of vehicle locations. Further, other conventional display technology (e.g., liquid crystal display (“LCD”), light emitting diode (“LED”), etc.) incorporate a lens and is located in a module (e.g., wherein the lens is a first or exterior surface and the display is a second or inner surface). (The lens is typically used to cover or obscure circuit boards and the like.) Additionally, conventional display technology (particularly LCD displays) are only used in a flat and/or non-flexible surface application. To provide a reliable, widely adaptable, self-illuminating vehicle display that is less expensive, has higher contrast, and uses less energy than conventional displays (e.g., LCDs, and the like) and avoids the above-referenced and other problems would represent a significant advance in the art.
<SOH> SUMMARY OF THE INVENTION <EOH>A primary feature of the present invention is to provide a vehicle display which provides interior designers with enhanced flexibility and aesthetics. Another feature of the present inventions is to provide a display system which requires little space and which may be located in a wide variety of locations within a vehicle interior. Another feature of the present inventions is to move the display to the first surface and provide a vehicle display that does not require a lens. A different feature of the present inventions is to provide a display which may be placed over, rather than within, a vehicle interior component and may resemble a contoured surface profile. Yet another feature of the present inventions is to provide a display surface which yields a high quality display of any one or more kinds of data, including but not limited to safety, vehicle condition, entertainment, educational and status data. Another feature of the present inventions is to provide a display which may be installed using assembly techniques which are commonly used to install trim covers, including installation on curved surfaces, whether they be convex or concave. How these and other objects of the present inventions are accomplished, individually, collectively or in various subcombinations will be described in the following detailed description of preferred and alternate embodiments, taken in conjunction with the FIGURES. Generally, however, they are accomplished by using a thin, flexible display screen or sheet (such as organic light emitting diode (“OLED”), LCD material, flexible LCD, thin film electro-luminescent (“TFEL”), or other suitable display technology, and preferably organic sheet of light-emitting diode material. The display may be in any shape (e.g., square, circular, oval, etc.) and may be applied over a variety of interior surfaces, including but not limited to the instrument panel, consoles, door, pillar, side trim panels, etc. More than one such display sheet may be employed for displaying the same or different information. The display screen can be the first surface (e.g., the exterior surface exposed to the passenger compartment), recessed behind a plastic (protective) substrate, sprayed or poured into a recess (e.g., OLED), insert molded, etc. The information displays can be fixed in place using the same trim hardware as is currently used to cover the pillar with leather, vinyl, fabric, foam and other cover materials. Alternatively, the display sheet may be attached using mechanical fasteners (such as snaps, screws, clips, etc.), other fasteners (such as Velcro® hook and loop fasteners), sewing, adhesives, etc. Also, the display sheet can be insert molded along with a fabric material or other aesthetic or functional article. This ease of assembly makes adoption of the display to different types or sizes of vehicles much easier than would be the case in conventional applications (e.g., if deep recesses, holes, apertures, etc. were required to receive thicker display devices). Also, protecting the display is intended to enhance reliability and reduce cost associated with damaged displays. The color of the display sheet can also be coordinated with the remainder of the vehicle interior. Other ways in which the various features of present invention can be accomplished will be described later herein, and still others will appear to those skilled in the art after they have read this specification. Such other ways are deemed to fall within the scope of the present invention, if they fall within the scope of the claims which follow. Additionally, the displayed image may be provided by ultraviolet (“UV”) light being projected through a substrate with or without an insert or over-molded fabric. The present invention further relates to various features and combinations of features shown and described in the disclosed embodiments. Other ways in which the objects and features of the disclosed embodiments are accomplished will be described in the following specification or will become apparent to those skilled in the art after they have read this specification.

<SOH> BACKGROUND ART <EOH>The starting ignition and low-load stable combustion of the conventional industrial coal boiler will consume a great amount of burning oil. For example, in the year of 1999, the electric power industry of China consumed about 13.65 million tons of oil. Research and development of pre-combustion chamber have been conducted since more than ten years, and great success has been made in the technique of multi-fuel combustion of coal and oil near the nozzle of the pulverized coal burner by means of a miniature oil gun. The oil-saving effect of said technique is prominent. However, so far, there is no combustion-enhancing miniature oil gun and combustion-enhancing pulverized coal burner having the function of internal combustion of pulverized coal. Consequently, the oil-saving effect is limited and the economic performance of the electric power industry is affected adversely.
<SOH> SUMMARY OF THE INVENTION <EOH>Therefore, an object of the invention is to provide an ignition and burning apparatus used in coal boiler and capable of saving oil considerably. Said object is realized by the following ignition and burning apparatus used in coal boiler.

<SOH> BACKGROUND OF THE INVENTION <EOH>Idiopathic nephrotic syndromes due to primary glomerular diseases include the minimal change nephrotic syndrome (MCNS), the focal segmental glomerulosclerosis (FGS), the membranous nephropathy (MN), and the membranoproliferative glomerulonephritis (MPGN). Patients with these diseases fall into hypoproteinemia due to the loss of substantial amounts of protein in the urine during the nephrotic stage, and in order to compensate for the loss, protein synthesis is accelerated in the liver. The four disease types above are finally diagnosed by taking a sample of the kidney (renal biopsy), and testing the sample with a light microscope and an electron microscope, and also testing the sample through the immunofluorescent antibody method. This diagnostic process is a large burden on the patient and requires time and labor for the histological examination. Therefore, there has been a demand for a diagnosis method for the nephrotic syndromes by using blood serum or urine, which are relatively easily available. The present invention aims at providing a new diagnosis method. Through this method, the patient can be relieved of the biopsy. At the same time, this method enables the distinction between the MCNS and the FGS, in which the clinical feature is similar to MCNS.
