Patent JP-S566080-A (JP)
Title: Axial piston pump
Inventor: HIRAYAMA HIROSHI
IPC: F04B1/20
Filed: 1979-06-25
Abstract: PURPOSE: To reduce noise by a method wherein between an inlet port and a discharge port of valve plate an orifice and a slit are respectively formed on the valve plate.  
     CONSTITUTION: At the changing point from an inlet stroke to a discharge stroke a cylinder chamber 8' expands ready to become negative-pressured. However, in order to connect with the adjacent long hole still in the connected condition with the inlet port 6' through a slit 11, the pressure is supplied therefrom to prevent the becoming negative-pressured. After passing the upper dead point the precompression is going to start but at this moment through an orifice 12 the air is partly discharged to the low-pressured side from the notch groove 18 of the external pad part 17 thus to reduce the peak pressure. Thereby by forming the orifice and slit on the valve plate the peak and negative pressure can be eased up preventing the capacitive efficiency degeneration thus to reduce the noise accompanying the pressure change.

Title: Resin sealed type semiconductor device
Inventor: ISHII SHIGEO
IPC: H01L23/31
Filed: 1982-05-14
Abstract: PURPOSE:To improve moisture resistance and thus form a product of high reliability by a method wherein semiconductor oxide glass is interposed between a semiconductor nitride film formed on the surface of a semiconductor element as the final protection film and a resin body. CONSTITUTION:The adhesion property between the resin sealed body 6 is removed by forming the second phosphorous silicate glass (PSG) film 11 on the surface of the plasma nitride film 10. The second PSG film 11 is coated to the thickness of approx. 0.2mum at approx. 400 deg.C by a CVD (chemical vapor deposition), etc. The resin molded body 6 contacts this second PSG film 11 and surrounds it. As the film covering the surface of the plasma nitride film, an SiO2 glass without content of phosphorus can be adhered instead of PSG. By interposing the thin film of PSG or CVD-SiO2 glass between the plasma nitride film the final passivation and the resin molded body, the adhesion property between the both is enhanced, the exfoliation of the resin molded body between the passivation film is not generated, parts as the sump of water infiltrated through the resin molded body, etc. are eliminated, and accordingly moisture resistance can be improved.

Title: Rinsing method for epitaxial growing apparatus
Inventor: TAKAHASHI TSUGINORI
IPC: H01L21/3065
Filed: 1981-05-28
Abstract: PURPOSE:To rinse an epitaxial growing system by utilizing a spattering effect of gas ions generated by electric discharge. CONSTITUTION:A quartz reaction tube 1 of an epitaxial apparatus is provided with an electric-discharge mechanism P consisting of a high-voltage power supply 2, a stabilized resistor 3 and positive and negative electrodes 4 and 5. When a high voltage is impressed on both electrodes 4 and 5, discharge begins, plasma is thereby generated in the tube, and particles having high energy, such as argon ions, in the ambience of plasma, are accelerated by a strong electric field in the vicinity of the negative electrode and strike at a carbon boat which is the negative electrode 5. These particles perform spattering of impurity atoms adsorbed on the surface of the boat, together with the atoms of the surface layer thereof. An effect of spattering occurs also when the particles strike at the wall of the reaction tube 1. The impurity atoms separated from the surfaces of the reaction tube 1 and the carbon boat 5 in this way are exhausted out of the reaction tube.

Title: Radio wave responder
Inventor: YAMAGUCHI MIKIO
IPC: G01S13/82
Filed: 1987-03-31
Abstract: PURPOSE:To simplify the titled responder and to reduce it cost by providing an antenna on a resonance circuit by a coil and a capacitor consisting of a superconductive material. CONSTITUTION:An antenna 51 is provided on a resonance circuit by a coil 52 and a capacitor 53 consisting of the superconductive material. In this state, when a radio wave of a resonance frequency is received from the antenna 51, energy of its radio wave is stored in the resonance circuit. In this case, when the radio wave comes not to be received, the stored energy is emitted from the antenna 51, and an electric oscillation is attenuated. In such a way, by applying the resonance frequency, a location of a radio wave responder can be confirmed. Also, the enclosure 54 of the radio wave responder is formed in a shape of a thin plate, therefore, it becomes convenient to stick it to an object to be confirmed, or to be crimped. In such a way, the titled responder can be simplified, and also, its cost can be reduced.
