Title: Voltage control circuit for switching regulator
Inventor: ASANO FUMIO
IPC: G05F1/56
Filed: 1977-11-22
Abstract: PURPOSE: To form simplified voltage control circuit capable of making use of the advantages of both modes by controlling the electrification of switching element for switching regulator by using a combination of a frequency modulation mode and a pulse width modulation mode.  
     CONSTITUTION: The circuit consists of the driving circuit flip-flop 4 to drive the switching element Q 1 , the voltage comparators 2 and 3 to compare the output voltage VOUT of regulator with the refrence voltage VC and then to control the condition of the flip-flop 4 so that the output voltage VOUT of the regulator is within the normal range, and the oscillator 1 transferred forcibly to the condiction in which the switching element Q 1  interrups the flip-flop 4 periodically regardless of the level of the output voltage VOUT. With this mode, it is possible to obtain voltage control circuit taking advantage of both modes; that is, one to control by a mode similar to frequency modulation mode at the time of light load, and the other to control by a mode similar to pulse modulation mode at the time of heavy load.

Title: X-ray microscope
Inventor: SUGIZAKI KATSUMI
IPC: G21K7/00
Filed: 1994-06-22
Abstract: PURPOSE:To facilitate the handling of samples and obtain an X-ray microscope with a highly efficient X-ray optical system by providing a housing chamber whose degree of vacuum is lower than that inside a vacuum container to be provided. CONSTITUTION:This microscope is structured by providing a partition 102 and a low-pressure sample chamber 100 sealed by an X-ray transmitting window 103 in a vacuum lens tube 6 and installing a sample capsule 104 of an open type in the chamber 100. Since the X-ray transmitting window 103 in the low- pressure sample chamber 100 has only to separate the low pressure in the sample chamber 100 from the vacuum in the vacuum lens tube 6, the differential pressure is little and the X-ray transmitting window 103 need not be very strong. Consequently, it is possible to use the thin X-ray transmitting window 103 with a good X-ray penetration. Moreover, the pressure in the low-pressure sample chamber 100 is required to be as much as or higher than such steam pressure as not to vaporize a culture solution for holding a sample 24. As the space of the low-pressure sample chamber 100 absorbs few X rays, the sample 24 can be observed in a highly efficient X-ray optical system.

IPC: F25B1/10
Filed: 1990-05-29
Abstract: PURPOSE:To prevent the seizure of a compressor, by a method wherein the inside of the closed shell of a low-stage compressor is connected to the inside of the closed shell of a high-stage compressor, by piping, and thus a lubricating oil for the low-stage compressor can be sent to the high-stage compressor. CONSTITUTION:In a refrigeration cycle, a lubricating oil contained in a refrigerant gas discharged from a high-stage compressor 1 flows into an intermediate heat- exchanger 4 through a condensor 2 and a first expansion valve 3, and the lubrication oil contained in the refrigerant gas discharged from a low-stage compressor 7 is also led into the intermediate heat-exchanger 4, and is mixed together with the lubricating oil discharged from the high-stage compressor 1. The lubricating oil mingled in condensed liquid of the refrigerant is sucked into the low-stage compressor 7 and returned into a closed shell, and thus it is stored in the closed shell of the low-stage compressor 7. When the lubricating oil becomes above the proper level thereof, the lubricating oil flows in a pipe line 8 and is sent into the closed shell of the high-stage compressor 1 through a pipe line 9, by an auxiliary pump 10 in operation, and when the lubricating oil for the low-stage compressor is lowered to the proper level, it is not sent any more. As the result of it, the lubricating oil level of each of the compressors can be always kept properly and the failure such as seizure can be prevented.

Title: Daylight device for automatic vending machine
Inventor: SAYAMA MASATOSHI
IPC: G07F9/02
Filed: 1993-06-14
Abstract: PURPOSE:To obtain the device which has a wide variable range of the time of automatic lighting and facilitates setting operation by fitting a sensor to a light collecting window movably in an approaching/leaving direction. CONSTITUTION:A linear slide groove 17 is formed in a main body along an approaching/leaving direction and a projection 18 which engages with the slide groove 17 is formed on a fitting block 15. A cadmium sulfide (cds) cell 5 is stuck on the fitting block 15. The base end part of a male screw 12 projects outside the main body and is mounted with a knob 19. Consequently, the male screw 12 is rotated by operating the knob 19 and the photodetection surface of the cds cell 5 moves out or in by a distance corresponding to the screw pitch. Thus, the cds cell 5 changes in set position to and away from the light collecting window 3 in the approaching/leaving direction to decrease the quantity of incident light in proportion to the square of the distance when the cds cell 5 is moved away from the light collecting window 3, so that the quantity of light incident on the cds cell 5 greatly varies only by slight rotating operation of the knob 19.

Filed: 1990-05-29
Abstract: PURPOSE:To prevent leaking of sound generated outside by employing a double shall structure of inlet and outlet intake headers where the front and rear sides of a heat exchanging section are covered with plate-shaped bodies forming a header for cooling water. CONSTITUTION:Header bodies 12 and 13 are both a double shell structure respectively comprising outer shells 12a and 13a and inner shells 12b and 13b. A space for proofing sound is formed between the outer shells 12a and 13a and the inner shells 12b and 13b. Hot intake air enters a header 11 on the side of an outlet for suction via an intake port 16 and flows upward inside the header being dispersed to each flat pipe 2 to be discharged at an intake outlet 15 via the inside of a header 10 on the side of an outlet for suction. On the other hand, a cooling water enters a header 20 on the side of an inlet for cooling water via a cooling water supply port 21. Thereafter, with actions of middle headers 24, 25 and 26 and bars 7 and 8, the cooling water flows through a zigzag path P and enters a header 22 on the side of an outlet for cooling water to be discharged at a discharge port 23. Thus, a hot intake is cooled down by the cooling water flowing through a cooling water passage section 5 when flowing through the flat pipe 2.

Inventor: YOSHIKAWA MASAHIRO
IPC: F23G5/50
Filed: 1993-05-21
Abstract: PURPOSE:To permit the maintenance of stabilized combustion condition continuously by a method wherein combustion air is controlled so that a difference between an operated air excessive rate and a set reference air excessive rate is corrected. CONSTITUTION:The amount of oxygen in exhaust gas is operated by the sum of the amount of oxygen in combustion air 7 and the amount of oxygen in secondary air 11 to obtain the amount of oxygen consumed by combustion. Next, a primary air excessive rage is operated by dividing the amount of oxygen in the combustion air 7 by the amount of oxygen consumed by combustion, then, the primary air excessive rate is compared with a reference air excessive rate set by the amount of calorific power of waste 3, while the amount of combustion air 7 is controlled so as to eliminate the difference. According to this method, the supply of combustion air 7 can be controlled in accordance with the nature of the waste 3, changing at all times, as well as the complicated relation in the conditions of combustion whereby stabilized combustion condition can be maintained continuously.

Title: Branching filter
Inventor: DAI YUUKICHI
IPC: H01P1/213
Filed: 1977-11-24
Abstract: PURPOSE:To constitute a branching filter featuring a small amount of loss only with the function of the line and thus to omit the high-cost amplifier, the composite coupler and others. CONSTITUTION:Input coaxial line 3 is divided into N-pieces of coaxial line L featuring different length l at branching point 2, and then led to BPF.FL which makes pass the signal of the desired frequency by the length of l. Now, if the length of l is set to lambda0/4 under the premise that the input impedance of BPF is close to the short circuit at the blocking band of each filter, input frequency f1 is shown in the diagram. Impedance Z1 when the short-circuit side is viewed from point 2 becomes infinity  with l = lambda0/4. In other words, the signal of f1 passes through FL1 to emerge at the output without being attenuated at point 2. In such way, the input signal passes through point 2 with a low loss regardless of the branching number to be divided into f1-fN.

Title: Piston valve controller for constant negative pressure type carburetor
Inventor: MOTOSUGI KATSUHIKO
IPC: F02M7/17
Filed: 1979-11-02
Abstract: PURPOSE: To improve the acceleration performance by opening a negative pressure introducing passage leading to a negative pressure chamber of a variable venturi type carburetor to the atmosphere for a certain period of time, thereby retarding the timing of the piston valve ascending so as to increase the density of a mixture.  
     CONSTITUTION: If a throttle valve 6 is opened suddenly during the engine operation, the intake negative pressure at downstream of the throttle valve 6 is suddenly decreased to be as low as the atmospheric pressure. This change of the negative pressure is transmitted to the inside of the first chamber 10e of a valve 10 through a negative pressure duct 10h. As a result thereof, a diaphragm 10d of the valve 10 is moved to the leftward against the force of a spring 10g provided within a second chamber 10f which is under the atmospheric pressure. Accordingly, a valve member 10b moves leftwardly due to the force of another spring 10c so as to open an air passage 9. On the other hand, at the same time of the throttle valve opening rapidly, the negative pressure at the venturi part is increased. However, as the negative pressure passage 8 is opened to the atmosphere through a control jet 9a, the negative pressure within a negative pressure chamber 4 is prevented from increasing thereby suppressing the piston valve 2 from lifting. Accordingly, a mixture of a high density is fed to the engine.

Title: Image pick-up device
Inventor: OOTAKE TSUTOMU
IPC: H01L31/08
Filed: 1981-09-08
Abstract: PURPOSE:To produce an image pick-up device where the high resistance layer of amorphous silicon is grown quickly on a conductive film, by forming the conductive film as the transparent electrode with at least one of CdSnO3-x(0<=x<=1), Cd2SnO4-x(0<=x<1) or CdSn1-x SbxO4(0<=x<1). CONSTITUTION:The powder of Cdo, SnO2, Cd and Sn is weighed and mixed to provide CdSnO3-x(0<=x<1) then encapsulated in Pt tube and heated under 1,000 deg.C for 20hr. Since the pressure in the tube increases it is performed while pressurizing with 1 Kbar. Thereafter it is cooled gradually to produce CdSnO3-x(0<=x<1). Said material is employed to form a film of approximately 2,000Angstrom  on a glass substrate 21 through the spattering. Said film will have the permeability of 75-80% in the audible region and the considerably low resistivity of 1X10<-2>OMEGA- cm thus provided with the performance of the transparent electrode. Then n-type a-Si layer 23 and highly resistive a-Si layer 24 are provided on the transparent electrode 22 through the plasma CVD method while furthermore Sb2S325 is formed through the vacuum deposition.

Title: A laminated ceramic capacitor
Inventor: YAMASHITA YOHACHI
IPC: H01G4/258
Filed: 1990-06-01
Abstract: PURPOSE:To prepare a highly reliable ceramic capacitor having a flat capacity temperature coefficient, good temperature characteristic, and sufficient electrical and mechanical strength by using dielectric materials which are different in temperature characteristic as ceramic dielectrics on both the upper and lower surfaces of a substrate of the capacitor. CONSTITUTION:Since in a laminated ceramic capacitor consisting of a substrate and ceramic dielectric substance the substrate lies between the first ceramic dielectric 3-1 and second ceramic dielectric 3-2 made of dielectric materials which are different in temperature characteristic from each other via an electrode 2, an internal stress is absorbed by the substrate that is generated due to the difference in thermal expansion coefficient between the dielectric 3-1 and dielectric 3-2. Therefore, this capacitor causes no degradation of the electric characteristics of the ceramic dielectrics and less threatens to generate a crack caused by the lowering of the mechanical strength thereof. Further, in a laminated ceramic capacitor of the present invention there is no fear that material diffusion occurs between the dielectric 3-1 and the dielectric 3-2 and hence flattening the capacity temperature coefficient is effectively achieved. With this, an extremely highly reliable laminated ceramic capacitor is prepared that has a superior temperature characteristic, and good electrical characteristics and mechanical strength.
