Abstract: In a switch device, a metal stamping has a first group of connector terminals arranged in one line among plural lines of arranged connector terminals and is constructed by one metal stamping together with a wiring pattern. The metal stamping is subjected to an insert molding process to form an insert molding. A second group of connector terminals, arranged in another line, among the connector terminals arranged in plural lines, are formed from parts of metal pieces which are separate from the metal stamping. The second group of connector terminals are press-fitted in the insert molding. In the switch device, the manufacture of the metal stamping requires minimal bending steps, and the manufacture can be achieved with the use of a simple stamping metal mold.

Abstract: A process for producing carbon fiber or graphite fiber is provided. The process comprises spinning a carbonaceous pitch, doubling spun pitch fiber bundles, adding a heat resistant doubling treatment oil, passing the fiber bundles continuously and linearly through an oxygen rich gas, infusibilizing at a temperature of 350.degree. C. or less, then carbonizing or graphitizing infusibilized fiber bundles.

Abstract: Extremely high modulus carbon fibers can be produced by carbonization at a substantially lower temperature, for example, at about 2500.degree. C. This is made possible by selectively stabilizing only an outer surface layer portion of a carbonaceous pitch-based fiber comprised mainly of optically anisotropic components, while retaining the inner portion of the fiber in a non-stabilized state and without damage to the crystallinity thereof.
