Abstract: PURPOSE:To hold a pressure in a crank chamber approximately at a set value during running of a compressor. CONSTITUTION:A case 29 arranged to a head 3 is partitioned into an atmospheric chamber A and a valve chamber B by means of a bellows 33 in which a spring 37 is arranged. The valve chamber B is communicated with a crank chamber through a pressure introduction passage 39 and a communicating passage 38. A valve hole 29c formed in the case 29 such that the valve chamber B is communicated with a suction chamber S is openably closed by a ball valve 36 energized through the force of the spring 37. When a pressure in a crank chamber C is reduced to a value lower than a set value, a valve mechanism is closed to stop gas reduced from the crank chamber C to the suction chamber S. Reversely, when the pressure exceeds the set value, the valve mechanism is opened to reduce gas from the crank chamber C to the suction chamber S.

Title: Clean room
Inventor: NAKAGAWA KENJI
IPC: F24F7/06
Filed: 1989-01-10
Abstract: PURPOSE:To construct a clean room simply and economically by securing a highly clean work area by a down-flow method. CONSTITUTION:Provisions are made for a partition 1 which divides an operating section 2 from a non-operated section 3, a filter 5 and a fan 6 which are disposed overhead and a space 7 under the partition 1 where the air is circulated. The constitution is such that the air lifted by the fan 6 is delivered through the filter to the work area 4 so the air flow in the work area 4 may be down- flow. By causing a down-flow only in the work area 4, and causing an up-flow in the non-work area 8 for recirculation, the clean level at the work area 4 can be enhanced. In this embodiment, the area where dust is liable to be generated is separated from the work area 4. Combined with the relative shrinkage effect of the work area 4, a clean room can be constructed which is simple, economical and highly clean.

Title: Manufacture of information recording medium and information recording medium made by the same
Inventor: SHIRATORI TSUTOMU
IPC: G11B7/24035
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To form a desired recording mark and to obtain a good reproducing characteristic by forming a recording film having a prescribed film thickness on an information track without substantially depositing the recording film on each inclined part having a nonparallel surface to the surface of an information track on a substrate. SOLUTION: A land part having a flat surface parallel to the surface of the substrate is formed between grooves in the substrate surface, and this land part is used for the information track. The inclined part that is nonparallel to the substrate surface is formed on either side of the information track, and a recording layer consisting of a magneto-optical recording material and a phase changing recording material, etc., is laminated on the substrate surface. Almost no recording film or an extremely different characteristic film from the recording film on the information track is stuck to the inclined part on either side of the information track.  Consequently, even when recording is performed on the information track beyond both its sides to the inclined parts, the inclined parts are not substantially recorded, and hence the width of the mark to be formed is limited to the area of the information track.

Title: Nonvolatile semiconductor memory cell
Inventor: ANDOU AKIRA
IPC: H01L21/8247
Filed: 1982-01-12
Abstract: PURPOSE:To provide a nonvolatile MOS semiconductor memory cell which has good memory retension and small conductance standing wave by increasing the thickness of an interlayer insulating film only for the edge part of the first polycrystalline silicon film to become a floating gate. CONSTITUTION:Since an oxidized silicon film 7 is formed on the edge part of the first polycrystalline silicon film 4 covered with the second polycrystalline silicon film 6 of a control electrode, the interlayer insulating film of the part can  be formed thickly larger than the second film 5 formed as an ordinary interlayer insulating film. Since the area of the film 7 formed as an interlayer insulating film of the edge part of the first film 4 is less than approx. half of the  area of the first film 4 to become a floating gate, the film 5 formed as an ordinary interlayer insulating film is formed relatively thinly, thereby enabling to  reduce the conductance constant of a nonvolatile MOS transistor having two  layer electrodes.

Title: Electromagnetic brake gear
Inventor: TSUCHIYA AKIRA
IPC: F16D65/18
Filed: 1980-01-18
Abstract: PURPOSE:To eliminate the need for the characteristics of adsorption and desorption by making the magnetic reluctance rp, re1, re2, ro, rg of a permanent magnet, a yoke body, a magnetic-pole core, an adsorber and a void between the yoke body and the magnetic-pole core to be rp>>rg>>re1+re2+ro. CONSTITUTION:When a power source to exciting winding 13 is at OFF, the magnetic flux phip of a permanent magnet 11 hardly flows through a void 16 between a yoke body 15 and a magnetic-pole core 12 because the magnetic reluctance rg of the void 16 is larger than the sum re1+re2+ro of each magnetic reluctance of the yoke body 15, an adsorber 14 and the magnetic-pole core 12, and braking due to the adsorption of the adsorber 14 is conducted. Magnetic flux phie obtained by flowing currents through the exciting winding 13 is magnetic flux passing through the void 16 because the internal resistance rp of the permanent magnet 11 is brought to a condition of rp>>rg, and mutually denies with the magnetic flux phip of the permanent magnet 11, and the adsorption working of the adsorber 14 is denied. A spring for releasing braking is not needed in this invertion, and a secular change of adsorption and desorption does not happen.

Title: Temperature compensation type active bias amplifier
Inventor: KAMIOGURA AKIHIRO
IPC: H03F1/30
Filed: 1988-01-12
Abstract: PURPOSE:To keep the signal gain of an amplifier circuit constant independently of the change in temperature by connecting an operational amplifier whose noninverting input terminal is connected to a thermister to a base terminal of a transistor(TR) for active bias. CONSTITUTION:The thermister 15 is connected to the noninverting input terminal 12b of the operational amplifier 12 whose output terminal 12c is connected to a base terminal 4a of a TR 4. Thus, the output terminal voltage of the amplifier 12 is fluctuated largely due to a slight temperature of the noninverting input voltage. That is, when the base voltage of the TR 4 is increased at a low temperature. When the base voltage is increased, the current flowing to the resistor 7 is reduced and a drain current of an FET 1 being a current division flowing to the resistor 7 is also decreased. That is, the gain increased at room temperature in case of non-compensation is decreased by reducing the drain current at a low temperature and the gain is increased by increasing the drain current at a high temperature. As a result, the temperature compensation function keeping the gain constant independently of temperature is provided.

Filed: 1988-01-11
Abstract: PURPOSE:To need no contact holes and to make a direct exposure of a portion melted off easily, by using a silicide layer or a high melting point metal layer as the portion melted off. CONSTITUTION:A field oxide film 1 is formed on a P-type silicon substrate 8 by selective oxidation method. On a part of the substrate 8, an n<+> diffusion layer 7 is formed by thermal diffusion of phosphorus. Then, a layer-to-layer insulating film 2 is formed on the field oxide film 1. Nextly, a two-layer wiring structure made of an aluminium wiring 4 and a silicide layer 3 is formed on the layer-to-layer insulating film 2 so that it is connected to the n<+> diffusion layer 7. For formation of a silicide portion for melting off in a part of the silicide layer 3, aluminum is removed from the specified area. Then, an SiO2 cover film 6 is formed except for the silicide portion. Since there is only the SiO2 cover film 6 on the silicide wiring 3 for melting off, the cover film 6 has only to be removed from the specified area for exposure of silicide of the position melted off 10. By this method, there is no need of contact holes and a direct exposure of silicide of the portion melted off can be made easily.

Title: Charged particle deflection device
Inventor: NISHIHARA SUSUMU
IPC: H05H7/04
Filed: 1991-01-18
Abstract: PURPOSE:To realize desired deflection by providing a magnetic field generator to generate a magnetic field for canceling the leakage magnetic field out of the magnetic space, at the inlet and outlet where charged particles come in and go out. CONSTITUTION:As achromatism lowers due to the leak magnetic field out of the inlet and outlet of charged particles, two polar magnets 6 are placed in the opposite direction to the magnetic field formed by magnetic poles 1, 2 to cancel the leakage magnetic field and to work the magnetic field perpendicularly to the incidence direction of the charged particles. Thus by inclining the shape of a magnetic pole 7 and strengthening the magnetic field more near the magnetic field space, the leakage magnetic field is corrected more efficiently. If the magnitude of the magnetic field is inclined, more accurate correction is possible. Therefore, the effect of leakage magnetic field is eliminated to attain desired deflection.
