Abstract: PURPOSE:To improve the press workability of a galvanized steel sheet by adding a very small amt. of polyvinylpyrrolidone to a pure galvanizing bath acidified with sulfuric acid and carrying out cathodic electrolysis in the bath. CONSTITUTION:Polyvinylpyrrolidone is added to a pure galvanizing bath acidified with sulfuric acid by 1-1,000 ppm and cathodic electrolysis is carried out in the bath at 70-200A/dm<2> current density to produce an electrogalvanized steel sheet. The desired polymn. degree of the polyvinylpyrrolidone is about 50-5,000. The galvanizing is usually carried out at about 30-70 deg.C temp. of the bath and about pH0.5-2.0. Zinc is thickly deposited by about >=50g/m<2> and a galvanized steel sheet having superior press workability can be produced.

Title: Semiconductor device and its manufacture
Inventor: MIURA HIDEO
IPC: C23C16/52
Filed: 1994-09-19
Abstract: PURPOSE: To provide a semiconductor device structure which is formed by using a polycrystalline layer which is mainly aligned in specified crystal face orientation, and a specified means. CONSTITUTION: A layer 3 is formed in which the impurity concentration in the vicinity of the interface 30 of a base film 2 on a substrate l is controlled to be extremely low (infinitely close to zero) as compared with that of the film inside or to be sufficiently high. Thereby the crystal face orientation after a silicon layer 4 is crystallized is aligned mainly in specified crystal face orientation, so that mechanical characteristics like the internal stress of a thin film and electric characteristics of a semiconductor element formed in each crystal grain of polycrystalline silicon are improved. The thickness of a silicon thermal oxidation film formed by oxidizing the surface of the polycrystalline silicon thin film can be made uniform. Since the orientation of a crystal face can be controlled in the specified crystal face direction, an uniform polycrystalline layer wherein the value of internal stress is controlled can be stably obtained.

IPC: H01H21/50
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a slide switch. SOLUTION: Regarding a slide switch 10, an operation lever 30 turns, when an operation knob 30a fitted to one end thereof is caused to slide. In this case, a moderating projection 35b on a leaf spring 35 fitted to the operation lever 30 travels under engagement with a moderating groove 52 formed on a moderation forming part 50. In this case, a moderating groove peripheral member 54 is made of a hard material and, therefore, free from abrasion, in spite of the repeated use of the slide switch 10. Furthermore, as a bottom projection 56 capable of coming in contact with moderating projection 35b is formed on the bottom of the moderating groove 52, a force acting on the moderating groove peripheral member 54 at the time of contact with the moderating projection 35b can be dispersed, and a switch operation sound can reduced.
