It is known to make tanks from composite materials for various purposes. There has been considerable prior art in general for double-walled tanks for puncture resistant underground storage of environmentally hazardous chemicals, for example. There is a need for tanks and pressure vessels for the containment of fuels for aerospace and military applications. The new launch vehicles for NASA and DOD require extremely light weight hardware that is compatible with the containment of cryogenic liquid fuels and oxidizers.

2. Description of the Related Art
Portable terminals, for example, personal digital assistants (PDAs) or mobile terminals, have increasingly come into wide use. These portable terminals have a high-grade camera module having a zoom function and an auto focus function according to customer's requirements.
The zoom function refers to a function in which the focal length of a lens is varied and thus the size of an image of a subject for photography produced on an image sensor is varied. Further, the auto focus function refers to a function in which a distance between a lens and an image sensor is adjusted or the curvature of the lens is varied and thus an image of a subject for photography is most clearly produced on the image sensor.
A lens module having the above-described two functions including the zoom function and the auto focus function, i.e., a zoom lens module, generally includes at least two lens groups, and adjusts a distance between the at least two lens groups, thus embodying the zoom function.
Such a zoom lens module has a structure including mechanical components, such as a gear, a screw member, and a clip member, to convert a rotary motion of a driving source into a rectilinear motion of the lens group, and a cam member to achieve the interlocking movements of the at least two lens groups.
However, the above zoom lens module has the above-described plural mechanical components to vary the distance between the respective lens groups, and thus has an increased volume and a relatively long assembly time
to prevent unintentively making a connection. Thus, a semiconductor device constitute the restraint signal generating circuit can perform a stable and authentic operation. Further, since the command signal generating lap can be configured in assorted ways and to realize a minute fuse pitch, it is possible to increase the consolidation density of a semiconductor device. 1.
