Title: Output current detecting circuit for direct current high voltage power source
Inventor: YAMAGATA SHIGEO
IPC: H02M3/28
Filed: 1986-07-28
Abstract: PURPOSE:To detect an output current correctly with a simple circuit, by a method wherein the error of detection, effected by the charging current of a stray capacitor, is cancelled by a bias proportional to the voltage of the primary side of a transformer. CONSTITUTION:An adder 10 is provided with the value of the D.C. voltage of the primary side of a transformer 3, which is obtained through a detector 8, and the value of an output current, obtained through an amplifier 7. The value of the D.C. voltage corresponds to the amount of current which flows through the stray capacitor of a secondary side coil, therefore, the correct detected-current value, which does not include the error of detection effected by the stray capacitor, may be taken out of the output of the adder 10.

Title: Semiconductor memory device
Inventor: NAKASAKI YASUTAKA
IPC: H01L29/78
Filed: 1980-12-12
Abstract: PURPOSE: To improve performance and manufacturing process, by making an inter-layer insulating film of Si 3 N 4  aquired through a direct thermo-nitric process of poly Si, piling up poly Si, and forming an unvolatile memory device of stray gate structure consisting of double-layered poly Si gates.  
     CONSTITUTION: Si 3 N 4  has higher dielectric strength and constant. If a poly Si gate 8 is thermo-nitrated and an inter-layer insulating film is formed, the dielectric strength between layers will be improved as compared to that of SiO 2  with the same film thickness. The threshold voltage before injection decreases because of high dielectric constant. As the capacitance coupling between gates 6 and 8 increases, the injecting efficiency is improved. If the film thickness is made thinner to have the dielectric strength to a usual degree, the injecting efficiency will increase much higher with lower initial threshold values, and the performance of stray gate unvolatile memory will be improved greatly.

Title: Inspecting device for defect of thin film
Inventor: TANABE YOSHIKAZU
IPC: G03F1/00
Filed: 1982-10-08
Abstract: PURPOSE:To enable even the inspection of a very minute defect such as a very small change in a film thickness, by detecting an interference ray generated by the application of a light onto a thin film and by measuring the change in the intensity of the interference ray. CONSTITUTION:When a light 4 having a wave surface (ab) is applied onto a resist film 2 as a thin film and reflected thereby, a surface reflection light 13 passing through (b), being reflected at (d) and entering a prescribed point and a back-surface reflection light 14 being refracted at (a), falling into the resist film 2, being reflected at (c) and refracted again at (d) and entering the same light-receiving point are different in a time required for reaching the light-receiving point. Accordingly, when the light 4 in the same phase at (ab) is received by a spectroscope after being reflected by the resist film 2, a difference is caused in the phase and the back-surface reflection light 14 passing through (a), (c) and (d) is delayed when it is superposed on the light 13. As the result, an interference occurs. When the thickness of the resist film 2 changes, the degree of the difference in the phase also changes with said change, and thus the optical component of an intensified color changes as well. By measuring the optical component of this intensified color, the very small change in the thickness of the resist film 2 can be inspected.

Title: Fuel injection quantity controller for internal-combustion engine
Inventor: ANZAI KATSUSHI
IPC: F02D41/22
Filed: 1984-08-27
Abstract: PURPOSE:To prevent an engine stall and a starting failure from occurring, by installing a knock sensor trouble discriminating device, discriminating anything unusual in a knock sensor, and a fuel increment device increasing a fuel injection quantity when this knock sensor trouble is found out. CONSTITUTION:A fuel injection quantity operational device calculates a fuel injection quantity tau according to the specified operating state parameter of an internal-combustion engine. A knock sensor trouble discriminating device discriminates trouble happening in the knock sensor installed in the engine. An engine cooling water temperature detecting device detects engine cooling water temperature THW. When something trouble in the knock sensor is discriminated, a fuel increment device increases the fuel injection quantity tau in response to the cooling water temperature THW. In time of an output failure in the knock sensor at low temperature, fuel increment can be brought down to zero or lessened as far as necessary. Thus, an engine stall due to smoldering in a spark plug and a starting failure or the like are all preventable.

Title: Method of observing shape of surface of charged particle source
Inventor: SASAKI ISAO
IPC: H01J37/285
Filed: 1982-10-08
Abstract: PURPOSE:To enable the shape of the charged-particle discharging surface of a charged particle source without taking it out from the vacuum by electrically detecting the intensity of discharge of particle rays two-dimensionally or three-dimensionally corresponding to the shape of the charged-particle discharging surface such as concave or convex. CONSTITUTION:In observing the distribution of the intensities of charged particle rays two-dimensionally, an image corresponding to the intensity of the charged particle ray is two-dimensionally displayed on a CRT displayer 12 by varying the deflection voltages of power sources 4 and 5 correctly, for example, in the same manner as raster scanning. For instance when the charged particle rays are not deflected, the largest part of charged particle rays entering into a Faraday cut 9 are those discharged from the center of the pointed end of a charged particle source. When the charged particle rays are deflected leftward, the largest part of charged particle rays entering into the Faraday cup 9 are those discharged from the right section of the pointed end of the source. As a result, an image corresponding to the shape of the particle-ray discharging surface of the charged particle source can be obtained by deflecting and scanning the charged particle rays.

Title: Grain conveying air lift unit
Inventor: FUKUMITSU DAIZABURO
IPC: B65G53/46
Filed: 1986-07-28
Abstract: PURPOSE:To make it possible to convey a material such as grain with a high density by pneumatic conveyance under a generally used low pressure, by using a rotary feeder and an air lift pump in combination. CONSTITUTION:Air under pressure fed from a blower 3 on operation flows through an air pipe 4 into an air lift pump 5 and then flows upward through a porous air filtrable plate 12 so that the air penetrates into a material to be conveyed, which has been accumulated on the plate 12, to float up the material. Therefore, the material is led along the surface of the plate inclined at a set angle, into the opening end part of a conveying pipe 6. The material to be conveyed ascends through the pipe 6 from the opening end part having been buried in the material, in a semi-float condition, and changes it direction, and therefore, the material is discharged horizontally from a discharge port 7 into a container 20 as a destination. Air containing dust, which has accompanied with the material so as to be discharged into the container 20, flows through suction ports 8 that are formed in parallel in the upper and lower parts of the discharge port 7, and through a return pipe 9 under suction force by the blower 3, and is compressed by the latter after being purified by a bag filter 10 so that it is reformed into conveying air which circulates through the system.

Title: Device for operating variable speed pumped storage power generation system
Inventor: TANOUE DAISAKU
IPC: H02H3/20
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To continuously operate a variable speed pumped storage power generation system even when a fault occurs by giving a restarting command to an inverter for a prescribed period of time after the cancellation of an operation stop command outputted from a protecting means when the voltage drop is detected in a power system. SOLUTION: When a DC overvoltage or a DC overcurrent occurs in an inverter (IT) or the IT outputs an AC overcurrent, a overvoltage relay 11, an overcurrent relay 12, or an overcurrent relay 13 detects the overvoltage, overcurrent, or overcurrent. The outputs of the relays 11-13 become gate stop commands through an OR circuit 21 and the gate of the IT is shut off. The outputs of the relays 11-13 are held by means of a hold circuit 23 and become system stop commands or circuit breaker trip commands and stop a variable speed pumped storage power generation system after the set period of time of a time-limiter circuit 24 has elapsed. When a short- circuiting fault or ground fault occurs, on the other hand, the voltage of the system drops and a drop detcting circuit 20 detects the voltage drop. The output of the circuit 20 cancels the holding state of the circuit 23. When the set time of a timer circuit 25 comes, a pulse generating circuit 26 restarts the IT by giving a restart command to the IT.

Title: Production of spherically shaped body
Inventor: SHIMIZU YOICHI
IPC: A61M1/10
Filed: 1991-06-21
Abstract: PURPOSE:To stably obtain a spherical body with high sphericity, by a method wherein a density gradient continuous in vertical direction is set in a specified liquid when a spherically shaped body used as an artificial valve for an artificial heart is shaped by pouring a liquid material to be shaped into the specified liquid and by hardening it during its flotation. CONSTITUTION:A density gradient continuous in the direction of depth is formed in a liquid 35 in which a solution 28 of material to be shaped is poured when a ball is shaped. This density gradient is linearly changed and needs to be formed in the liquid 35 per se. In this way, the solution 28 poured is allowed to behave so as not to float or sink more than the solution needs, and is allowed to harden while floating and receiving equal force from the whole periphery thereof, at the position where the solution 28 is balanced with the liquid 35, and thus the solution 28 is spherically shaped in the condition that impact is not applied, and the ball with high sphericity can be obtained. As the liquid 35, a single polymer or solution is used, in which protective colloid or a surface- active agent or the like is added, and as the solution 28, a dual-soluble, room temperature setting type monomer or the like is used.
