Abstract: PROBLEM TO BE SOLVED: To reduce the parts cost and assembling cost by making the shaft of an impeller from a plastic material and forming a bearing for rotatably supporting one end of the shaft integrally with a piping. SOLUTION: An impeller 2 is molded with a plastic material mixed with a magnetic powder, a shaft 3 is made of a well lubricant plastic material such as fluoro resin, polyacetal resin, etc., and fixed to an axial line position of the impeller 2 by the drive-fitting, etc., e.g. three stays 1a are projected from a piping 1 at the downstream of the impeller 2 to its center axis.

Title: Manufacture of semiconductor device
Inventor: GOTO HIROSHI
IPC: H01L21/302
Filed: 1987-10-20
Abstract: PURPOSE:To form a sidewall gently connected onto the top face and bottom of a stepped section by etching a layer shaped onto the stepped section (a protruding section) in an anisotropic manner when the sidewall of a semiconductor device is formed, chemically changing a residual layer on the surface of the stepped section and removing the changing section through etching. CONSTITUTION:A polysilicon film 4 is approximately 0.6mum thick in thickness on a gate insulating film, and an silicon nitride film 5 is formed continuously onto a substrate through a stepped section from the upper section of a polysilicon gate 3. The polysilicon film 4 is etched in an anisotropic manner through RIE by using CBrF3 or CF4-Br2 gas up to an extent that the polysilicon film 4 in thickness of approximately 0.1mum on the gate insulating film 5 is left. An SiO2 film 4a is shaped through thermal oxidation by wet oxidation at a temperature of approximately 1000 deg.C. Consequently, the base 6 of the SiO2 film 4a formed onto the base of the stepped section takes a shape having an easy slope through the anisotropic etching of RIE. The SiO2 film 4a is removed through wet etching by employing HF, and the sidewall 4b of polysilicon is formed.

Title: Friction arm
Inventor: NAKAZAWA YASUMITSU
IPC: E05C17/28
Filed: 1992-09-03
Abstract: PURPOSE:To secure such a sliding force as suited to the tilting degree of a 'shoji' screen extending over the whole stroke of its opening or closing operation as well as to make easy and smooth opening or closing operations performable. CONSTITUTION:A slider 9 to be installed in the end of a friction arm 5 is formed by means of a connection between both halved members 9a and 9b. There is provided a coil spring 11 which presses these halved members 9a, 9b to wall surface of a groove of a vertical door case. Next, a bearing opening part 16 to be fitted with a slider pivot 8 installed in the end of the friction arm 5 is formed in space between both these halved members 9a and 9b. A form of the opening part 16 is formed into being tapered off toward a traveling direction of the slider at a time when a 'shoji' screen is energized by its own weight and opened or closed. If the slider 9 tries to open so quickly, the slider pivot 8 pushes these halved members 9a, 9b open wide, pressing them strongly to the groove, whereby braking force grows larger, so a 'shoji' screen on-off speed becomes uniformized.

Title: Sorting method
Inventor: SASAKI HOZUMI
IPC: G06F7/24
Filed: 1989-10-11
Abstract: PURPOSE:To shorten the time required for sorting by using n-step cascaded discriminating and storing means and a control means. CONSTITUTION:After n-step of discriminating and storing parts 21 to 2n are cascaded and are initialized, discriminating and storing parts 21 to 2n compare input data with data stored in storing parts. When input data is larger or smaller, input data is stored in storing parts to store input data in storing parts in the ascending or descending order. Since a control means 3 generates at least n-number of shifted clocks to supply them to corresponding discriminating and storing parts 21 to 2n at the time of input of one clock, the processing of one data is all completed with one clock. Thus, the time required for sorting is shortened.
