Title: Reciprocating type compressor
Inventor: FUKUCHI KAZUYA
IPC: F04B39/00
Filed: 1985-11-15
Abstract: PURPOSE:To reduce the quantity of leaking gas at a shaft seal by providing a powder scraping mechanism and a powder reservoir on the shaft seal part of a piston rod. CONSTITUTION:A powder produced by the reaction of water in the air with a UF6 gas, is deposited on a piston rod. The powder deposited on the surface of the piston rod is scraped off by a powder scraping brush 11, and the powder which was scraped off is collected in a powder reservoir 12. Accordingly, a leaked gas can enter a first chamber 14 passing through a clad seal 9. Thereby, the quantity of leaking gas at a shaft seal can be reduced, saving the capacity of a cold trap for recovering shaft-seal exhaust.

Abstract: PROBLEM TO BE SOLVED: To provide a video display device capable of executing a contour correction in accordance with feature of video such as a color component, a contrast difference and the high frequency component of frequency. SOLUTION: This video display device uses a luminance/chrominance signal separator 2 to separate a video signal into a luminance signal 3 and a chrominance signal 4, a green detector 5 detects whether or not the color signal 4 is a green component and outputs the result of detection as a control signal to control the operation of a contour correction device. When the result of detection indicates the presence of the green color component, a contour correction section 6 applies contour correction to the luminance signal 3 and the chrominance signal is added to the luminance signal corrected by the contour correction and a display section 7 displays the video.

Title: Rotor of rotary electric machine
Inventor: SHIOMI HIDEKAZU
IPC: H02K3/48
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To equalize thickness of coil corner in the width direction and prevent generation of discrepancy due to interlayer dielectric breakdown during high speed rotation, by loading an interlayer insulator previously shaped to realize close contact with a gap of coil corner section formed by bending a flat copper belt. SOLUTION: When a coil corner section 5 of an edgewise bending magnetic field coil 4 is formed by buckling of the field coil 4 formed by stacking plural sheets of flat air copper belt 3, the internal side is formed rather thick. When the field coil 4 is formed by stacking a plurality of sheets of the flat angular copper belt 3, a cross-section in the triangular shape is formed in the gap between the coil corners 5. The gap of cross-section in the triangular shape is loaded with the interlayer insulator 7 previously shaped in contact with the gap of cross-section in the triangular shape. Therefore, an equal force is applied to the interlayer insulator 7 which is closely in contact in the gap.  As a result, the interlayer area is never locally compressed, stress concentration due to the centrifugal force applied to the field coil can be dispersed equally even when the rotor rotates at a high speed, and interlayer short-circuiting can be prevented by avoiding internal layer dielectric breakdown.

Title: Manufacture of amorphous silicon image sensor
Inventor: SOEDA SHINICHI
IPC: H01L27/146
Filed: 1985-11-18
Abstract: PURPOSE:To simplify the manufacture process by performing the electrical isolation of a Pin-amorphous-Si film by means of a step provided on the substrate, thereby eliminating the requirement of strict mask alignment. CONSTITUTION:On a substrate 10 a lower electrode 11 is formed, and with this as a mask a step portion 10a is formed in the peripheral portion of the electrode 10. Then, a continuous Pin-a-Si film 12 is formed on the substrate 10 and the electrode 11 including the step portion 10a. In this case, since the film 12 is formed on the electrode 11 in a continuous shape, a strict mask alignment is not required. Then, an upper common electrode 13 is formed on the film 12. In the a-Si image sensor formed in this way, a high-resistance portion 12a is generated in the film due to the step portion 10a of the substrate 10, and even if the film 12 continues, the electrode 11 is electrically isolated, so that the respective elements can maintain the element characteristics respectively. With this manufacture process, mask alignment of the film 12 is simplified, and an inter-layer insulating film becomes unnecessary.

Title: Picture input device
Inventor: AKITA TORU
IPC: G06T11/80
Filed: 1989-09-29
Abstract: PURPOSE:To draw pictures with free touches via a free hand by detecting the pressure applied to the tip of a manual operation tool and calculating the spot diameter or the line diameter and the color gradation based on the writing pressure of the operation tool via a diameter calculation part and a gradation calculation part. CONSTITUTION:A writing pressure detecting part 8 calculates the writing pressure P from the detection signal received from a manual operation tool 6. A coordinate detecting part 9 obtains the coordinates X and Y from the detection signals received from an input board 7. A recessing part 602 is provided at the lower end of a tool main body 601 and a tip part 603 is slidably attached into the part 602, and a sensor for detecting the displacement DELTAl is provided. The displacement DELTAl is defined as the pressure P and the color gradation, i.e., the dot density is decided based on the pressure P. That is, the color gradation is calculated based on the relation between the writing pressure and the density and the relation between the writing pressure and the line diameter. Thus a thin and light color line is obtained with the small writing pressure, and a thick and dark color line is obtained with the large writing pressure respectively. Thus it is possible to input the different color density levels and different line diameters in the same way as that of an ordinary writing brush.

Title: Diagnosis device for life of bearing
Inventor: OGUMA NORIYASU
IPC: G01N29/14
Filed: 1989-10-02
Abstract: PURPOSE:To enable accurate diagnosis of service life by calculating a discharged energy of AE per unit time based on an amplitude of AE signal at the time when a signal is generated by a comparison means and the number of signals generated from the comparison means per unit time. CONSTITUTION:The AE signal with original waveform from a bearing is detected by an AE sensor 1. The AE signal, to which an A/D conversion 7 is made, is compared with a reference value Vh by a computer 8, and when it exceeds the value Vh, the amplitude of this AE signal is stored in a memory successively as AMPi. When a unit time is elapsed, each value of AMPi stored in the memory are integrated by the computer 8 and an average amplitude AMP is obtained by dividing the integrated value by the number of AE generation CL per unit time. Next, the discharged energy of AE at that time per unit time, CW = (AMP/Vh)CL is obtained. The energy CW is added to the integrated value D of discharged energy upto the previous time to make it the integrated value D' of discharged energy at this time. The integrated value D' is compared with a reference value SL and when D'>=SL, a life signal indicating that the bearing is used to the limit is outputted to a display circuit 9.
