Title: Semiconductor device
Inventor: HARUTA AKIRA
IPC: H01L29/78
Filed: 1986-07-07
Abstract: PURPOSE:To cause the interface between the surface of a semiconductor device and an insulation film to have compression stress for improving resistance to radiation of the semiconductor device, by forming on the top face of the semiconductor substrate a thin film whose internal stress is converted to tensile stress when deposited, or forming on the bottom face of the semiconductor substrate a thin film whose internal stress is converted to compression stress when deposited. CONSTITUTION:An MOS semiconductor device composed of a silicon substrate 1, a thermally oxidized silicon film 2 formed on the surface of the silicon substrate 1 and a active layer 3 provided thereon has a projected top face. Therefore, the interface between the silicon substrate 1 and the silicon oxide film 2 is subjected to tensile stress. When a silicon nitride film 4 is formed on the surface of the semiconductor device such that its internal stress is converted into tensile stress, the silicon nitride film 4 becomes to have a cross section projected on the bottom. Thereby, the interface between the surface of the semiconductor device and the insulation film, namely the Si/SiO2 interface is subjected to compression stress. Alternatively, when a silicon nitride film 5 is formed on the bottom face of the semiconductor device, the film 5 becomes to have a cross section projected on the bottom, whereby the Si/SiO2 interface is subjected to compression stress. Thus, it is possible to decrease interface levels produced at the Si/SiO2 interface when irradiated with X-radiation. A semiconductor device having improved resistance to radiation can be obtained in this manner.

Title: Semiconductor storage device
Inventor: SAKAI KIKUO
IPC: G11C11/409
Filed: 1983-08-31
Abstract: PURPOSE:To make plural output stage circuits fast and slow in operation timing differently, and reduce noise generated on a power line by providing delay circuits selectively between main amplifiers for specifying output timing and output stage circuits. CONSTITUTION:An output buffer consists of eight couples of main amplifiers MA0-MA7 and output stage circuits OB0-OB7, and an 8-bit readout signal is sent out from external terminals DO0-DO7. Delay circuits DL1-DL4 are interposed between the even-numbered main amplifiers MA1, MA3, MA5, and MA7, and output stage circuits OB1, OB3, OB5, and OB7. Therefore, plural output buffers which require relatively large currents do not operate at the same time and the device enters time-series operation while divided into two according to the time difference set by the delay circuits, so noise generated on the power line are suppressed small.

Title: Preparation of novel pectinase
Inventor: SHIMADA KIYOU
IPC: C12N9/26
Filed: 1982-09-10
Abstract: PURPOSE:To obtain a novel pectinase effective for removing endocarp of mandarin, by cultivating a fungus capable of producing a novel pectinase in a medium so that the novel pectinase is prepared and accumulated in the medium. CONSTITUTION:A fungus belonging to the genus Penicillium capable of producing a novel pectinase is cultivated in a medium, the novel pectinase is prepared and accumulated in the medium, and it is collected. Although solid cultivation has the highest activity in a case that an enzyme is prepared from a common fungus, this fungus capable of producing pectinase can secrete almost the same activity by liquid culture as that by solid culture when a distillation residue of alcohol fermentation is used as the medium. The activity of the novel pectinase is unstable at <=3.5pH, and the pectinase is deactivated, so the reaction can be stopped by adding a very small amount of pH adjustor after endocarp of mandarin is removed. Decomposition of juice sacs can be prevented easily, to prepare mandarin for high-quality canned provisions.

Title: Vibration-proof support device
Inventor: NISHIDA TOSHIO
IPC: F16F7/10
Filed: 1983-08-31
Abstract: PURPOSE:To provide a mechanical vibration-proof support device which is simple in structure and small-sized to reduce the cost by filling a piston reciprocating space with a lot of small steel balls and providing an inertia valve to control the movement of the small steel balls. CONSTITUTION:Piston reciprocating spaces 11, 12 in a cylinder 2 are filled with a lot of small steel balls. A piston 1 is provided with an inertia valve 3 adapted to open and close passages 8a, 8b, 10 for connecting the spaces 11, 12 to each other. The inertia valve 3 is supported by balance springs 4a, 4b disposed on both sides thereof, whereby when the piston 1 moves suddenly, the inertia valve 3 lags behind the piston 1 against the balance springs 4a, 4b to intercept the passages 8a, 8b for connecting the spaces 11, 12 to each other, resulting in arresting the movement of the piston 1. For a slow motion of the piston 1, the inertia valve 3 will not move to keep the passages 8a, 8b in an open state, so that the piston 1 can be moved smoothly.

Title: Ferrite stainless steel-made bellows excellent in fatigue characteristic
Inventor: YAMAMOTO AKIO
IPC: C22C38/18
Filed: 1995-06-23
Abstract: PURPOSE: To prevent the occurrence of fatigue failure in a short time, eliminate stress corrosion cracking sensitivity, by setting ratio of thickness in a respective mountain of a bellows to thickness in a root part of minimum diameter to ratio or more of a diameter in a root part of minimum diameter to a diameter in each mountain part. CONSTITUTION: Bellows are formed from ferrite stainless steel containing 10.0wt.% or more 23.0wt.% or less Cr with a stable crystal structure of metal phase in body centered cubic at an ordinary temperature. Ratio of thickness in each mountain part of the bellows to thickness in a root part of minimum diameter is set to ratio or more of a diameter in a root part of minimum diameter to a diameter in each part. In this way, a work hardening effect is also added with strength almost made uniform between mountain/root parts, to eliminate deformation concentrated on the mountain part. As a result, since substantially loaded stress is large reduced, a time till generating fatigue failure is markedly extended.

IPC: G11B7/085
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a disk device capable of conducting stable lens kick. SOLUTION: When a pickup 12 reads reproducing signals (RF signals) and tracking effor signals (TE signals), these signals are amplified by an RF amplifier 16 and the amplified RF and TE signals are waveformed in waveform forming circuits 18a and 18b, respectively.

Title: Cleaning method and device for plastic resin mold
Inventor: KUBOTA AKIHIRO
IPC: B29B13/00
Filed: 1978-12-20
Abstract: PURPOSE:To enable an efficient cleaning of contaminants adhered to a mold surface, by removing residual resins adhered to the mold surface by blasting air, whose temperature is sufficiently lower than that of a mold, and minute solid particles against a surface, wherein a molding cavity of a plastic resin mold is formed, immediately after molding is complete. CONSTITUTION:A cleaning head 15 is built into a cleaning device proper provided with a system reciprocating between an upper and a lower molds, an air nozzle 20, and a nozzle 21 which ejects particles such as minute walnut particles, etc., being located adjacent the end thereof. The cleaning head 15 is inserted into a mold 12 heated to high temperature immediately after a molding process. High pressure air having room temperature is then injected from the nozzle 20, minute solid particles are ejected from the nozzle 21 together with the high pressure air. This causes a rapid contraction of resins adhered to a cavity 12' of the mold 12, and as a result, an adhesion force thereof reduces sharply. In addition, the minute solid particles collide with the resins at a high speed, whereby the resins fall off from the mold 12. The resins are then exhausted together with the minute solid particles through an exhaust port 17 connected to a vacuum suction system.
