Title: Resist composition and pattern forming method
Inventor: KODACHI AKIKO
IPC: G03F7/26
Filed: 1992-07-15
Abstract: PURPOSE:To obtain a Si-contg. resist having enough resolution and sensitivity and showing no swelling during development by using a polymer having a specified structural unit in the molecule as the main component. CONSTITUTION:This resist compsn. essentially consists of a polymer having the structural unit expressed by formula in the molecule. In formula, R is an alkylsilyl group having at least one Si atom. By mixing this resist compsn. with a photo-acid initiator and using a resist compsn. consisting of this mixture, a film is formed, exposed to radiation, baked, and developed to obtain a pattern. Namely, in the poly(N-alkylsilyl maleimide) polymer having the structural unit expressed by formula, the alkylsilyl group is released by the effect of acid to change into NH group. Thereby, by using the mixture of the polymer and photo-acid initiator as a resist, polarity of the exposed part changes by exposure to radiation and baking and the resist can be developed.

IPC: H05K3/46
Filed: 1990-07-17
Abstract: PURPOSE:To reduce linear expansion coefficient of a part and to prevent peeling, swelling due to a thermal stress by providing a resin layer containing filler made of glass powder or SiO2 on a circuit surface of an inner layer material. CONSTITUTION:A resin layer containing 80-50vol.% of filler of glass powder on a circuit surface of an inner layer material. When SiO2 is used as the filler, a resin layer containing 2-7vol.% of the filler is formed. A multilayer printed circuit board is manufactured by laminating prepreg containing glass powder or SiO2 in contact with inner layer circuits 2b, 2c of the material 2, further laminating prepregs containing no glass or no SiO2 and the same foil at both sides, curing them by pressurizing, heating to form outer layer materials 3, 4, and forming outer layer circuits 3b, 4b by etching.

Title: Permanent magnet motor
Inventor: NAKAGAWA YUKINORI
IPC: H02K21/14
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a motor of high efficiency, low noise and low vibration in regard to a permanent magnet motor used for a drive source for a blowing fan of an air conditioner or the like. SOLUTION: In a permanent magnet motor, of which the number of rotor poles is eight and the number of stator slots twelve, two auxiliary grooves 5 are provided in the part of a tooth 1 opposite to a rotor and the grooves are positioned in two ways a long the axial length. In this case, the number of cogging pulsations per revolution of the rotor is larger than that in the case, where the groove position is in one way along the axial length, and thus the order of a cogging torque component can be made higher, and reduction in noise and vibration of the motor can be realized. Although the number of the auxiliary grooves is two in this constitution, the efficiency is not lowered, since an equivalent air gap is equal to one in the case, where the groove position lies in one way along the axial length.

Title: Press-in and pulling method of pile and press in and pulling machine
Inventor: YASUOKA KAZUHIKO
IPC: E02D7/20
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To enable press-in and pulling and generally apply to a hydraulic instrument by utilizing and improving an instantaneous high pressure generation phenomenon by oil shock for press-in of a pile into ground and pulling from the ground by expansion and contraction of a hydraulic cylinder. SOLUTION: A rigid pipe passage member 22 and a flexible pipe passage member 21 are connected in series, and an electrode opening and closing valve 11 and a check valve with a pilot 10 are connected. A fluid shock wave generated by the opening and closing valve 11 reciprocates and propagates in both the pipe passage members 21, 22 at sound speed, and the check valves responds thereto until it attenuates. Energy of the fluid shock wave is passed through the check valve 10, efficiently utilized for aiding expansion and contraction operation in a hydraulic cylinder 1, and energy efficiency is enhanced. In this case, the length of the pipe passage leading the fluid shock wave of a pile press-in and pulling machine is set at a half of a distance in which the fluid shock wave propagates in the pipe passage within the response required time of the check valve 10.  Thus even if fluid shock pulse pressure is received, early damage between both the pipe passage members 21, 22 is prevented, and occurrence of an accident resulting in injury or death by breakage of the pipe passage can be avoided.

Abstract: PURPOSE:To enable a measuring person to smoothly continue succeeding operations by making a symbol display corresponding to the stage of each prescribed state when the stage of said state is attained by the operation. CONSTITUTION:The symbols corresponding to requests are displayed 3 in the respective operation stages of, for example, the request for mounting test paper 25, the request for preparing a vital specimen liquid, the request for immersing the test paper 25 into the vital specimen liquid, etc. The measuring person, therefore, continues the measurement while understanding the contents of the succeeding operations by the symbol marks by viewing the display.

The photodetection current of the element 23 is taken via a current/voltage converter 28 and an analog-to-digital converter 29 to the CPU 26. The value of the ratio between the quantities of the light detected from the test paper prior to the immersion into the vital specimen liquid and after the immersion is calculated and the material quantity such as urinal sugar value is quantitatively determined from the value of such ratio in the CPU 26.
