Title: Radiant ray detector
Inventor: NISHIKI MASAYUKI
IPC: A61B6/03
Filed: 1982-05-28
Abstract: PURPOSE:To prevent deterioration of detection accuracy of a multi-channel type photodiode and the whole radiant ray detector, by forming a light output face of a scintillator element positioned at both ends to the same shape as the photodetecting face of a corresponding photodetector. CONSTITUTION:The light output face (bottom face) of scintillator elements 5A, 5E is notched toward the bottom face from the side so that its shape becomes same as the photodetecting face of photodetectors 3A, 3E. According to such a constitution, even if X-rays of the same X-ray quantity are made incident, fluorescent light generated by the scintillator elements 5A, 5E can be led completely to the photodetecting face of the photodetectors 3A, 3E, therefore, decrease of detection accuracy of an X-ray detector 1 can be prevented. Also, since an area of the light output face of the scintillator elements 5A, 5E is made small, the photodetecting face of the photodetectors 3A, 3E is available as it is small and it is unnecessary to lengthen the length of the longitudinal direction of a semiconductor layer 2, therefore, even if plural X-ray detectors 1 are arrayed one-dimensionally, the X-ray incident face of each scintillator can be arrayed at the same pitch, and deterioration of detection accuracy of the whole X-ray detector 1 can be prevented.

Title: Liquid jet recording head
Inventor: SHIMODA JIYUNJI
IPC: B41J2/175
Filed: 1984-05-08
Abstract: PURPOSE:To make it possible to perform high quality recording by preventing the generation of a satellite, by such a structure that the end surface of a filter in the side of a pressure generation part is obliquely formed. CONSTITUTION:Because the end surface 5a of a filter 5 is inclined at an angle of theta to the plane A crossing a straight line ink flow passage 1 at right angles, the presure wave generated in the ink flow passage is absorbed or attenuated by the vibration of a piezoelectric element 2 after the emission of ink without being acoustically reflected at the end surface 5a of the filter 5 different from a conventional one. Therefore, the change in pressure in the vicinity of an orifice 1a is reduced and the generation of a satellite is prevented. In this case, the magnitude of the effect for preventing the aforementioned satellite relates to that of the inclination angle theta of the filter and it is proper to set the angle theta to 10 deg. or more but, with due regard to stability when the filter 5 is fixed, it is pref. to set the upper limit of the angle theta to about 50 deg..

Abstract: PURPOSE:To improve the reliability of wafer attraction and subject the wafer to a stable plasma treatment by pressing an elastic member of a ground potential to the rear of the wafer at the time of subjecting the wafer held on a susceptor to the plasma treatment by an electrostatic attraction force. CONSTITUTION:The wafer 18 is imposed on the susceptor 11 in a vacuum treating chamber 1 and a gas for an etching treatment is introduced from a gas supplying pipe 6 into the chamber and is converted to plasma by the interaction of the microwave electric field generated by a magnetron 4 and the magnetic field generated by a solenoid coil 5. A high-frequency power is simultaneously impressed by a high-frequency power source 16 to the susceptor 11 to etch the wafer 18. The wafer 18 is imposed on the susceptor 11 by lowering an ejecting pin 14 and a conductive leaf spring 25 having elasticity is pressed to the rear of the wafer. The spring 25 is deformed to the same level as the surface level of the susceptor 11 by the weight of the wafer 18 and the electrostatic attraction force so that the wafer 18 is brought into sure contact with the conductive leaf spring 25 even if the wafer is warped. The attraction reliability of the wafer is thus improved and the wafer is subjected to the stable plasma treatment.

IPC: F04B49/08
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a controller used as an automotive drive controller for a variable displacement pump. SOLUTION: A variable displacement pump 11 is controlled by servo mechanism 37, 39 by a control pressure from a charge pump 21. As a pedal P of a vehicle engine E is depressed, an increasing pressure differential across a fixed orifice 79 moves a control spool 73 to port control fluid to a first servo port A. If engine speed becomes excessive, or in response to an external pressure signal 121 representing another vehicle condition, the control spool 73 is moved to a position in which control pressure is ported to a second servo port B, thus positively reducing the displacement of the pump.
