Title: Housing structure of portable apparatus
Inventor: OKAZAKI HIDETOSHI
IPC: H05K5/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To thin a housing partially, to reduce the weight, and to maintain the strength simultaneously by providing thin parts formed by reducing the thickness relatively, forming links two-dimensionally so as not to join the thin parts to one another. SOLUTION: A molded housing is composed of a reference thickness part 6a having a reference thickness and thin parts 6b formed more thinly than the reference thickness part 6a. These thin parts 6b are holelike but are not penetrated, and are in the shape of circles, ellipses, near circles, polygons, etc., for example when looked from above, and they are arranged forming links two-dimensionally so as not to touch one another. When an arbitrary thin part 6b is considered to be a reference, a plurality of thin parts 6b for example are arranged along a group of radial direct lines with the thin part 6b as the center forming about 60 degrees with each other. By forming the thin parts 6b by arrangement like this, it becomes possible to wrap up the thin parts 6b by the reference-thickness part 6a like honeycomb construction, and to maintain the strength.

Abstract: PURPOSE:To restrain the deterioration of morphology of high melting point metal silicide, and prevent the increase of wiring resistance by heat-treating a high melting point silicide thin film which is formed on a substrate and has thermal condensation property, in an atmosphere containing hydrogen.

Title: Liner for floppy disk jacket
Inventor: NISHIGUCHI MAYUMI
IPC: G11B23/033
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress deposition of dust on a disk which is conventionally produced by a liner and can not be removed, by adding a specified amt. of a specified antistatic agent to a nonwoven fabric essentially comprising an acryl fiber. SOLUTION: This liner for a floppy disk jacket is obtd. by impregnating a nonwoven fabric having an outer layer comprising 100% acryl fiber and an inner layer containing other fibers by >=10% except an acryl fiber with an antistatic agent having <=3 average number of ethylene oxide residues in one molecule by 0.1-0.5wt.%. By using the liner, dust produced in the production process of a floppy disk can be easily removed and decrease in the production yield due to dust can be avoided. Moreover, since the liner essentially consists of an acryl fiber, the liner hardly causes dropping of lints or roughening or fuzzing of the surface and has good punching property. As for the antistatic agent to be added, a compd. containing no ethylene oxide is most preferable.

When a switching signal which switches the switch r is outputted from the computer K, the switch R is switched. As the result, the control signal from the switch S is outputted as the DTMF signal by the oscillator (n) and is outputted to a line through the switch E and a changeover switch Q. Thus, the number of input ports of the computer K is reduced.
