The present invention is concerned with a finger tilting apparatus for a transfer feeder which is preferably employable for a transfer press or the like industrial machine so as to allow a finger to be tilted relative to a feed bar. The apparatus includes an angle defining element for defining an angle of rotation of the shaft portion of a finger and an angle stopping element for stopping rotation of the shaft portion of the finger at a rotation angle different from the rotation angle defined by the angle defining element so that the finger is tilted via plural steps.

A transfer feeder equipped on a transfer press is provided with a pair of feed bars arranged in parallel with each other to perform three-dimensional movement by cams, levers or the like members so that a work is clamped by fingers situated at opposing positions of the feed bars so as to allow the work to be transferred between adjacent working stations in a press housing.
Since a commonly used transfer feeder is constructed such that fingers are held immovable relative to feed bars, it is impossible to change the attitude of a work depending upon the shape of a die.
Accordingly, for example, when the work is to be lifted up from the die, a lifting operation can be performed only via a straight track with the result that a lift stroke is unavoidably elongated and thereby it becomes difficult to reduce a time required for transferring the work.
If the shape of the die does not fit the attitude of a work to be clamped by the fingers, the work can not correctly be placed in the die. This means that there is existent a certain restriction with respect to dies which can be put in practical use.
To solve a problem of such inconvenience, a proposal is already disclosed, e.g., in an official gazette of Japanese Utility Model Application NO. 190,222/1975 that fingers are supported to turn relative to feed bars via their shaft portions and a mechanism for rotating the shaft portions is provided to tilt the fingers relative to the feed bars. According to this proposal, a work is correctly placed in a die by adequately tilting the fingers in consideration of the shape of the die and reduction of a lift stroke is achieved by simultaneously performing a lifting operation and a tilting operation
Specifically, such a type of conventional finger tilting apparatus includes a plate adapted to be turned in operative association with the shaft portion of a finger, an elongated hole formed in the plate and a defining pin held on a vertical plate firmly secured to a feed bar and slidably fitted in the elongated hole so that a tilt angle of the finger is defined by allowing the defining pin to come in contact with opposite end faces of the elongated hole. With this apparatus of the type including such an elongated hole, the attitude of a work can be changed once only. Thus, for example, in case where a work is clamped while the finger is tilted, a lifting operation and a tilting operation can not simultaneously be performed when the work is to be lifted up (with the exception of a case where the finger is restored to its initial angle).
Further, in case where a tilt angle of the finger is to be changed, this is achieved by selectively fitting the defining pin into one of a plurality of different elongated holes preformed in the plate. Consequently, an attitude of the work can not be changed to an angle rather other than the tilt angles defined by the elongated holes. Thus, a requirement for changing the tilt angle in response to change or modification of the specification given to the work can not be met quickly.
The present invention has been made with the foregoing background in mind and its primary object reside in providing a finger tilting apparatus for a transfer feeder which assures that a finger can be tilted by way of plural steps.
A secondary object of the present invention is to provide a finger tilting apparatus for a transfer feeder which assures that a requirement for changing a tilt angle in response to change or modification of the specification given to a work can be met quickly.

A curable fluorosilicone resin composition is disclosed, which composition comprises. (A) 100 parts by weight of a fluorosilicone resin consisting essentially of F(CF.sub.2)aCH.sub.2 CH.sub.2 SiO.sub.3/2) siloxane units and, optionally, R.sub.b SiO.sub.(4-b)/2 siloxane units, wherein R is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms, a is an integer with a value of at least 4 and b is an integer with a value of 0 to 3, with the proviso that when said fluorosilicone resin contains said R.sub.b SiO.sub.(4-b)/2 siloxane units, the ratio of said F(CF.sub.2).sub.a CH.sub.2 CH.sub.2 SiO.sub.3/2 siloxane units to said R.sub.b SiO.sub.(4-b)/2 siloxane units is at least 1; PA1 (B) 1 to 90 parts by weight of a component selected from the group consisting of an organosilane and its partial hydrolysis product, said organosilane having the general formula R.sup.1.sub.c SiX.sub.4-c wherein R.sup.1 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms, c is 0, 1, or 2 and X is a hydrolyzable group; and PA1 (c) a sufficient amount of a condensation catalyst to accelerate the cure of said fluorosilicone resin composition.

A large number of organopolysiloxane resin-based compositions that cure to form water-repellent films are already known. For example, Japanese Patent Application Laid Open Number Sho 55-48245 discloses a composition of hydroxyl-containing methylpolysiloxane resin, alpha,omega-dihydroxydiorganopolysiloxane, and organosilane. This composition cures to form a water-repellent film that has excellent release and anti-stain properties. Japanese Patent Application Laid Open Number Sho 59-140280 discloses a composition based on the partial cohydrolysis condensation product from an organosilane mixture whose main components are perfluoroalkyl-containing organosilane and amino-containing organosilane. This composition cures to form a film having a good water repellency and oil repellency.

Systems and methods are provided that discover undesired advertisements on publisher web pages and automatically block advertisers or advertising channels associated with the placement of those advertisements from placing advertisements on the publisher web pages. An advertisement discovery and blocking system may discover advertisements on a particular publisher web page and placement pathways associated with those discovered advertisements. The system may then compare the discovered advertisements and placement pathways with a set of rules in an advertiser rule list. The system may detect advertisement violations based on the comparison of the set of rules in the advertiser rule list with the discovered advertisements and placement pathways. The system may add advertisers and advertising channels associated with the detected advertisement violations to a list of blocked advertisers. The list of blocked advertisers may be provided to the publishers and the advertising channels.

This invention relates generally to web-based information and, more specifically, to blocking of web-based advertisements.
Publisher websites such as newspaper web pages, television station web pages, web log web pages, magazine web pages, social networking web pages, microblogging web pages, and other internet-based online publishing sources often include advertisements for companies and products.
Advertisements on a publisher website may include images, videos, text, animations, or other visual or audio messages. These advertisements are sometimes referred to as advertisement creatives.
Advertisements may be placed on a publisher web page by a variety of sources. As examples, an advertiser may purchase an advertisement block on the publisher web page directly from the publisher, through an advertising network, through an advertising exchange, through a demand side platform (DSP) or through some combination of these or other advertising channels.
Because of these various pathways in which an advertisement can be placed on a given publisher website, it can be difficult for publishers to keep track of which advertisers are advertising on their webpage and which advertising channels are placing advertisements on their webpage. This can be problematic for publishers that desire to prevent undesired advertisements from being displayed on the publisher's website.
It would therefore be desirable to be able to provide improved systems for detecting and blocking undesirable internet-based advertisements.

A method and apparatus for coupling an Integrated Receiver Decoder (IRD) to a telephone line via a coaxial cable used for delivering direct broadcast satellite signals to the IRD. One embodiment comprises a port coupler, coupled to a telephone line and to the coaxial cable, and a client unit, coupled between the port coupler and the IRD, wherein the port coupler connects the IRD to the direct broadcast satellite signals and connects the IRD to the phone line via the client unit, and at least satellite signals, satellite control signals, telephone data signals, and telephone system protocol signals travel on the coaxial cable between the client unit and the port coupler.

1. Field of the Invention
The present invention relates generally to a satellite receiver system, and in particular, to a method and apparatus for connecting satellite receiver modems over coaxial cable.
2. Description of the Related Art
Satellite broadcasting of communications signals has become commonplace. Satellite distribution of commercial signals for use in television programming currently utilizes multiple feedhorns on a single Outdoor Unit (ODU) which supply signals to up to four IRDs on separate cables from a multiswitch.
FIG. 1 illustrates a typical satellite television installation of the related art.
System 100 uses signals sent from Satellite A (SatA) 102, Satellite B (SatB) 104, and Satellite C (SatC) 106 that are directly broadcast to an Outdoor Unit (ODU) 108 that is typically attached to the outside of a house 110. ODU 108 receives these signals and sends the+ received signals to IRD 112, which decodes the signals and separates the signals into viewer channels, which are then passed to television 114 for viewing by a user.
Satellite uplink signals 116 are transmitted by an uplink facility 118 to the satellites 102-104 that are typically in geosynchronous orbit. Satellites 102-106 amplify and rebroadcast the uplink signals 116, through transponders located on the satellite, as downlink signals 120. Depending on the satellite 102-106 antenna pattern, the downlink signals 120 are directed towards geographic areas for reception by the ODU 108.
Each satellite 102-106 broadcasts downlink signals 120 in thirty-two (32) different frequencies, which are licensed to various users for broadcasting of programming, which can be audio, video, or data signals, or any combination. These signals are typically located in the Ku-band of frequencies, i.e., 11-18 GHz. Future satellites will likely broadcast in the Ka-band of frequencies, i.e., 18-40 GHz, but typically 20-30 kHz.
FIG. 2 illustrates a typical ODU of the related art.
ODU 108 typically uses reflector dish 122 and feedhom assembly 124 to receive and direct downlink signals 120 onto feedhom assembly 124. Reflector dish 122 and feedhom assembly 124 are typically mounted on bracket 126 and attached to a structure for stable mounting. Feedhorn assembly 124 typically comprises one or more Low Noise Block converters 128, which are connected via wires or coaxial cables to a multiswitch, which can be located within feedhom assembly 124, elsewhere on the ODU 108, or within house 110. LNBs typically downconvert the Ku-band and Ka-band downlink signals 120 into frequencies that are easily transmitted by wire or cable, which are typically in the L-band of frequencies, which typically ranges from 950 MHz to 2150 MHz. This downconversion makes it possible to distribute the signals within a home using standard coaxial cables.
The multiswitch enables system 100 to selectively switch the signals from SatA 102, SatB 104, and SatC 106, and deliver these signals via cables 124 to each of the IRDs 112A-D located within house 110. Typically, the multiswitch is a five-input, four-output (5×4) multiswitch, but can also be a 6×8 multiswitch, where two inputs to the multiswitch are from SatA 102, two inputs to the multiswitch are from SatB 104, and one input to the multiswitch is from SatC 106. SatC 106 typically delivers local programming to specified geographic areas.
To maximize the available bandwidth in the Ku-band of downlink signals 120, each broadcast frequency is further divided into polarizations. Each LNB 128 can only receive one polarization at time, so by aligning polarizations between the downlink polarization and the LNB 128 polarization, downlink signals 120 can be selectively filtered out from travelling through the system 100 to each IRD 112A-D.
IRDs 112A-D use a one-way communications system to control the multiswitch. Each IRD 112A-D has a dedicated cable 124 connected directly to the multiswitch, and each IRD independently places a voltage and signal combination on the dedicated cable to program the multiswitch. For example, IRD 112A may wish to view a signal that is provided by SatA 102. To receive that signal, IRD 112A sends a voltage/tone signal on the dedicated cable back to the multiswitch, and the multiswitch delivers the satA 102 signal to IRD 112A on dedicated cable 124. IRD 112B independently controls the output port that IRD 112B is coupled to, and thus may deliver a different voltage/tone signal to the multiswitch. The voltage/tone signal typically comprises a 13 Volts DC (VDC) or 18 VDC signal, with or without a 22 kHz tone superimposed on the DC signal. 13 VDC without the 22 kHz tone would select one port, 13 VDC with the 22 kHz tone would select another port of the multiswitch, etc. The voltage/tone signal can also be a modulated tone with a voltage, such that more than four ports can be used and uniquely selected.
Further, some of the programs that are broadcast by SatA 102, SatB 104, and SatC 106 are "pay-per-view" programs, that are enabled and disabled through programming of the IRD 112. Typically, a customer will use a remote control to program the IRD 112, which then places a phone call to a customer service control point to enable a specific IRD 112 to decode the signals present on the pay-per-view channel.
Further, in some installations, each IRD 112 must be coupled to a phone line to enforce contractual blackout requirements, or for security reasons to assist in locating the IRD 112.
However, such services require that at least one, and possibly all of the IRDs 112 be installed physically proximate to the subscriber's television set and also require that the IRD 112 be installed such that a telephone line can be connected to the IRD 112. In some installations, new telephone lines must be run to the location within house 110 where the IRD 112 is located for the pay-per-view service to be activated. This increases the complexity and the cost of IRD 112 installation, and, in some circumstances, make it impossible to install an IRD 112 in a desired location because of the difficulty of running a telephone line to the desired location.
Other attempts at using internal house power lines to distribute telephone signals have been proposed, but the bandwidth of these systems cannot handle the other requirements that are necessary for the integration of satellite signal system distribution with such systems.
It can be seen, then, that there is a need in the art for a satellite broadcast system that can be easily installed in any location in a home. It can also be seen that there is a need in the art for a satellite broadcast system that utilizes pre-existing household telephone wiring to minimize cost and increase flexibility in arrangement of the system components.

This invention relates to a network control verification system, a control communication terminal, a server apparatus, and a network control verification method whereby a user away from a recording apparatus is notified of information such as whether the recording apparatus has completed unattended recording of a broadcast program as reserved. Specifically, a recording/reproducing apparatus 4 records a broadcast program to a recording medium in accordance with unattended recording reservation settings. The apparatus 4 extracts one picture frame from the pictures recorded on the recording medium and turns the extracted frame into a thumbnail image. The recording/reproducing apparatus 4 then transmits an e-mail including a recording start date, a recording start time, a recording stop time, a broadcast channel, and a recording mode regarding the recorded broadcast program to a mobile phone 53 together with an attachment of the thumbnail. By checking the e-mail sent to the mobile phone 53, the user can verify that the recording has been completed as reserved. This invention may be applied advantageously to networked electronic apparatuses.

1. Technical Field
The present invention relates to a network control verification system, a control communication terminal, a server apparatus, and a network control verification method for effecting remote control over electronic devices installed illustratively in the household via a communication network such as the Internet.
2. Background Art
There already exist unattended recording reservation apparatuses and program recording result display-apparatuses (e.g., refer to Japanese Patent Laid-open No. 2000-350142, pp. 2-3, FIG. 1) whereby reservations for unattended TV program recording are received from a remotely-located terminal PC through a telephone line and whereby a table of recorded programs according to the reservations is displayed on the terminal PC.
There are other related arrangements designed to receive program guide information from a TV program information providing company over the Internet, to record the received information by a video tape recorder, and to display a table of what was recorded (e.g., refer to Japanese Patent Laid-open No. Hei 10-164487, pp. 5-6); to provide broadcast programs recorded by an external server to a user terminal via the Internet (e.g., refer to Japanese Patent Laid-open No. 2002-84483, pp. 7-8); or to use a remote controller to set and modify unattended recording reservations on a video tape recorder through the Internet (e.g., Japanese Patent Laid-open No. 2001-8276, pp. 5-6).
Furthermore, there have been proposals which allow an Internet-ready portable data terminal to execute remote control over starting, stopping and reserving the unattended recording of broadcast programs onto a hard disc drive while having recording status (i.e., recording being underway or stopped, recording reservations being set or absent, and details of recording reservations) displayed on a mobile phone (e.g., refer to Japanese Patent Laid-open No. 2002-57686, pp. 6-9).
As outlined above, diverse remote control systems have been proposed, each allowing the user away from home to operate a portable communication terminal such as a mobile phone in order to remotely control a VTR, an air conditioner, or other electronic or electronic devices in the user's household by way of a public switched network and/or the Internet. Many of these systems, however, are confronted with such inherent problems as wasteful power dissipation, complicated system configurations, and high costs involved.
In many cases, electronic appliances subject to remote control must be powered continuously so as to be started up promptly as instructed. The system often needs to be extensive in scale using various devices for rapid and accurate remote control purposes.
Some solutions to the problems above have been proposed. One such solution, disclosed illustratively in Japanese Patent Laid-open No. 2002-078047, involves a simply-structured, inexpensively-configured remote control system for remotely controlling household electronic devices targeted for control without wasteful power dissipation.
The need to resolve the above-mentioned problems of power dissipation and extensive system configuration has entailed users' requirements further regarding the remote control system. Specifically, it is desired that household electronic devices such as VTR's be remotely operated more rapidly and accurately than before. Users of portable communication terminals are also desirous of verifying, away from home, whether any electronic device set for remote control is correctly operating in real time.
With today's widespread use of mobile phones and PDA's (personal digital assistants) having communication capabilities, a need has been recognized for a system which remotely controls electronic devices such as the VTR using such portable communication terminals and which allows the user to verify remotely whether the devices targeted for control are correctly operating.

A network device in a network may determine a tentative network address for a network interface of the network device and may determine whether the tentative network address is duplicative of any one of the network addresses in the network. If the tentative network address is duplicative of a network address assigned to another network interface in the network, the network device may store an indication of the other network interface. In response to receiving an indication that a new network address is assigned to the other network interface, the network device may re-determine whether the tentative network address is duplicative of any one of the network addresses in the network. If the network device determines that the tentative network address is not duplicative of any one of the plurality of network addresses in the network, the network device may assign the tentative network address to the network interface.

A computer network is a collection of interconnected network devices that exchange data and share resources. The network devices may be implemented as physical devices, such as desktop computers, servers, and network appliances, or may be deployed as virtual devices, such as virtual machines executing on virtualization infrastructure. In some networks, each network interface of the virtual or physical network device is assigned a unique hardware address, such as a Media Access Control (MAC) address.
A network device may autoconfigure its network interface in accordance with Internet Protocol version 6 (IPv6) when the network device joins a network segment of a computer network. For example, the network device may generate a link-local address for the network interface, which is a network address for the network interface that is valid only for communications within the network segment to which the network device is connected. The network device may also generate a global network address that is valid for communications within a network beyond the network segment. Because the network device may generate the link-local address prior to receiving indications of the link-local addresses associated with other network interfaces in the network segment, it is possible the network device may generate a link-local address that is already associated with another network interface in the network segment. Thus, when the network device generates a link-local address, the network device may perform duplicate address detection to verify the uniqueness of the link-local address within the network segment. Details of performing duplicate address detection are described in S. Thomson et al., "IPv6 Stateless Address Autoconfiguration," Network Working Group Request for Comments (RFC) 4862, September 2007.

Automatic recovery from duplicate network addresses


A medical laser delivery system usable to transmit laser energy from a laser energy source to a surgical site of a patient. The delivery system includes a handpiece adapted for rotatable coupling to a delivery arm coupled to the laser energy source such that the handpiece is rotatable about its longitudinal axis with respect to the delivery arm. A distal delivery system is coupled to the handpiece and delivers laser energy to the surgical site when the laser energy source is actuated. The handpiece includes a handpiece body adapted for rotatable coupling to the delivery arm and a handpiece head coupled to both the handpiece body and the distal delivery system. The handpiece head can be rotatably coupled to the handpiece body. In one embodiment, the handpiece head is angularly oriented at a fixed angle with respect to the handpiece body. In an alternative embodiment, the handpiece head is pivotally coupled to the body such that the handpiece head may be adjusted to various angles with respect to the handpiece body, such pivotal coupling preferably being accomplished by a ball and socket joint. A removable fiber extension is positioned within the handpiece and transmits laser energy from a fiber in the delivery arm to the distal delivery system. The distal delivery system includes an interchangeable delivery tip through which the laser energy is delivered to the surgical site. The tip can be a solid or hollow fiber of various sizes and shapes.

Lasers are widely used for many medical applications, both internal and external of a patient. The laser offers many advantages over conventional modalities, among which are its precision, its ability to achieve hemostasis, and its ability to sterilize the surgical site. One of its greatest potential advantages is its ability to access non-line of sight areas or areas of the body that are otherwise difficult to reach. However, current laser systems suffer from awkwardness, the inability to access many areas of the body, particularly in comparison to currently used older surgical instruments, and the inability to adequately ensure sterility of the parts of the laser that come in contact with the patient.
Neodymium doped Yttrium Aluminum Garnet (Nd:YAG) lasers, such as offered by American Dental Laser, are sometimes offered with bent handpieces which curve the distal end of the fiber at an angle of about 30 degrees over the last centimeter, but these systems are still cumbersome since the angled portion cannot readily rotate with respect to the axis of the fiber and the geometrical configuration is not optimum for oral cavity access. Handheld carbon dioxide (CO.sub.2) lasers, such as those manufactured by Directed Energy Systems or ILT, have a "delivery system" in which the distal end is too large and cumbersome to adequately reach into many parts of the body such as the oral cavity. The delivery system, such as it exists, consists of a focusing lens and a barrel of relatively large outer diameter. Articulating arm systems for CO.sub.2 lasers are not outfitted with small tips, which makes access to the back molars of the mouth, for example, very difficult.
An additional accessibility problem with both types of lasers as well as non-laser surgical instruments is the inability to vary the angle of the distal portion of the instrument with respect to the proximal portion. When using these prior art laser and non-laser instruments, it is necessary to completely switch instruments in order to achieve a proper angle. In addition to wasting valuable surgical time by switching instruments, the expense of surgery is greatly increased because of the requirement for duplicative instruments.


A semiconductor device includes a semiconductor substrate, a field oxide layer, a gate region and field plate integrated structure and a plurality of contact holes. A body region and a drift region are formed in the semiconductor substrate. An active region is formed in the body region, and a drain region is formed in the drift region. A field oxide layer is located on the drift region and the drift region surrounds a part of the field oxide layer. An integrated structure including a gate region and a field plate, the integrated structure extending from above the field oxide layer to above the body region. A depth of a contact hole closer to the source region penetrating into the field oxide layer is greater than a depth of a contact hole closer to the drain region penetrating into the field oxide layer.

With the continuous development of semiconductor technology, a Lateral Double Diffused MOSFET (LDMOS) device has good short channel characteristics. The LDMOS device has a lightly doped implanted region at the drain electrode, called the drift region. The lower the doping concentration of the drift region, the more the drift region is depleted, the higher the breakdown voltage (BV), and the greater the on-resistance (Rdson). Although the withstand voltage of the device is improved, the increase of the on-resistance will decrease the driving ability of the device. The higher the doping concentration of the drift region, the less the drift region is depleted, the lower the breakdown voltage, and the smaller the on-resistance. Although the smaller on-resistance improves the driving capability of the device, the voltage withstand capability of the device is reduced.
In view of the contradiction between the design of the breakdown voltage and the design of the on-resistance in the LDMOS device, in the conventional technology, the depletion of the drift region is mainly increased by using a field plate structure, and the withstand voltage is increased on the basis that the on-resistance is basically unchanged. The speed of the depletion depends on the thickness of the field oxide layer or the thickness of the shallow trench isolation (STI). The smaller the thickness of the field oxide layer, the greater the depletion of the drift region enhanced by the field plate structure. On the basis that the on-resistance is basically unchanged, the breakdown voltage can be increased. However, the thickness of the field oxide layer cannot be reduced infinitely, thus the depletion of the drift region cannot be enhanced infinitely, and the increase of the breakdown voltage is limited. In addition, the strength of the electric field between the drain electrode and the gate electrode will also limit the increase of the breakdown voltage, so that a breakdown is easy to occur after the field oxide layer between the drain electrode and the gate electrode becomes thin.
Therefore, it is necessary to propose a new LDMOS device to solve the above technical problems.
