Patent JP-S6017288-A (JP)
Title: Compression-capacity varying mechanism in slide vane type compressor
Inventor: SUGIURA MANABU
IPC: F04C28/10
Filed: 1983-07-09
Abstract: PURPOSE:To reduce the starting-up torque on starting by allowing a low-pressure chamber to communicate to the intake cycle in a compression chamber and allowing a high-pressure chamber to communicate to a discharge chamber and allowing a spool to transfer through the variation of the differential pressure generated between the pressure in intake cycle and the pressure in the discharge chamber. CONSTITUTION:Since a main intake hole 10A is in closed state by a spool 19 on starting, the coolant gas in an intake chamber is imbibed into a compressor chamber 6 only through a sub-intake hole 10B, and the small-capacity operation state is obtained. When the pressure in a discharge chamber 13 is increased gradually, said pressure variation is detected in pressure detection parts 23' and 24', and when the differential pressure between the both pressures (the pressure PD in the discharge chamber and the pressure PL in intake cycle) increase over the set pressure of a spring 22 in a control valve mechanism 12, the spool 19 is pushed towards a low-pressure chamber 21, and the intake hole 10A is opened, and the 100% operation state can be obtained. Therefore, the starting-up torque can be reduced.

Title: Inclination angle sensor
Inventor: NAKAGAKI TOSHIYA
IPC: G01C9/06
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To digitize a high-resolution angle signal by providing two pairs of photointerrupters for reading the phase of angle detection slits that are arranged at an equal interval in the circumferential direction of a disk that can be rotated smoothly while shifting them and a pair of photointerrupters for reading a base point signal. SOLUTION: A bearing 31 is fixed to a measurement target and a weight 1 is directed in gravity direction. Therefore, when the weight 1 is inclined around a shaft 3, the weight 1 and a disk 2 rotate around the bearing 31. At this time, photointerrupters 41-43 pass the slits of the disk 2, thus outputting ON/OFF signals from its light reception element. The signals of a leading point 0 deg. of the interrupter 41 is obtained, the edge change of the interrupters 42 and 43 is counted, and the edge change in the interrupters 42 and 43 is detected, thus measuring the angle change digitally. When the disk 2 rotates, rotation is suppressed by a weight 1 and an eddy current damping means and the influence of turbulence can be suppressed, thus improving a mechanical resolution.

IPC: B65H3/06
Filed: 1987-05-22
Abstract: PURPOSE:To surely prevent double feed of sheet by providing a means for stopping rotary driving of a feeding member when a first sheet is separated from the feeding member. CONSTITUTION:Upon operation of a drive motor 21, a feed roller 13 and a take-out roller 14 are rotary driven, and the frontmost single sheet 12 is fed out. When the rear end of the single sheet 12 separates from the feed roller 13, the single sheet 12 is further fed out with the leading end thereof being held by a pair of carry-out rollers 16, 16 so as to interrupt light being transmitted from a light emission element 17. Consequently, a stop signal is fed from a control section 20 to the drive motor 21 so as to stop rotary driving of the feed roller 13. A second single sheet 12 is pressure contacted with the stopped feed roller 13. As a result, braking force is applied onto the second and following single sheets 12, thus preventing simultaneous taking-out of single sheet 12.

The thickness of the film after adhesion is 2 mum at a drawing-up speed of 50mm/min. This film is further baked at 800 deg.C (selected from a range of 700 - 1100 deg.C) for 30 min to form a humidity-sensitive film 2 and a pair of comb-shaped electrodes 3 are printed on the humidity-sensitive film 2 by a screen printing method and baked.

Title: Peak identification method for chromatography
Inventor: ITO MASATO
IPC: G01N30/86
Filed: 1987-05-25
Abstract: PURPOSE:To shorten processing time and to eliminate the influence of overlap peaks by determining the function corresponding to a peak area by using a retention time and peak height with respective peaks and selecting the function value percentage of the corresponding value from the function value percentages. CONSTITUTION:The value corresponding to the area is calculated in a function device 8 by a function f(tR, h)=htR, function f(tR, h)=h(tR<2>+alpha)<0.5>. The values of these functions and the function value percentage occupying in the total function value are stored in a result data storage device 9. The function value percentage determined from the immediate previous or assigned chromatogram is taken out of the storage device 9 and the matched percentage is judged to be the peak consisting of the same component and is outputted to an output apparatus 7. The numbers of the peaks of both the chromatograms coincide with each other if the peaks do not overlap at all and, therefore, the peak identification is executed from one-to-one correspondence simply by arraying the function values in descending order.

Abstract: PURPOSE:To prevent the deterioration of Schottky characteristics and series resistance, by a method wherein, after a surface protecting film is formed and polyimide as spacer is spread, resist is spread and patterned, and after electrode metal is deposited, and unnecessary metal and the resist are lifted-off, the polyimide is eliminated. CONSTITUTION:On a semiconductor substrate 101, a surface protecting film 102 and spacer 103 composed of polyimide are laminated in order: resist 104 is spread on the surface and is patterned; an aperture is formed by selectively eliminating the spacer 103 composed of polyimide and the surface protecting film 102. After electrode metal 106 is deposited on the surface, and unnecessary metal is eliminated together with the resist 104, the spacer 103 composed of polyimide is eliminated. As a result, the generation of notch between the gate electrode 106 and the surface protecting film 102 can be prevented, when a source electrode 107 and a drain electrode 108 are formed, in the later process, by using the alloy. Thereby, the deterioration of Schottky characteristics and series resistance can be prevented.
