Title: Flow rate control valve
Inventor: OOE TAKESHI
IPC: G05D7/01
Filed: 1980-11-12
Abstract: PURPOSE:To control stably and surely the flow rate to a fluid apparatus even for a high load, by connecting a linking path, where a pressurized oil is fed out, and a supply path, where the pressurized oil is supplied to the fluid apparatus, by a nonreturn valve which allows movement of the pressurized oil. CONSTITUTION:A flow rate control valve 6 feeds the pressurized oil, which is discharged from the first pump 1, to a power steering device 9 through a supply path 13, an orifice 16, and a supply path 14. A valve hole 18 is provided in a casing 15 of the control valve 6, and a spool valve 17 which is supported to slide freely in this valve hole 18 and is moved by the longitudinal differential pressure of the orifice 16 is provided. The pressurized oil from the second pump 10 is fed to a linking path 20, and a nonreturn valve 23 is provided between the linking path 20 and the supply path 13. When the longitudinal differential pressure of the orifice 16 is small and the valve is in the nonoperation position, the linking path 20 and a reflux path 22 are not cut off. When the load becomes higher and the longitudinal differential pressure of the orifice 16 becomes large, the valve 17 is moved to connect the linking path 20 and the reflux path 22, and the excess pressurized oil is returned to a tank 4, and the opening of the nonreturn valve 23 is reduced to make the quantity of the pressurized oil constant.

Title: Protective device for hybrid power transistor
Inventor: HIGASHIYAMA KATSUHIKO
IPC: H01L23/34
Filed: 1984-07-31
Abstract: PURPOSE:To obtain the titled protective device, wherein no voltage loss is generated at all, by a method wherein heat, which is generated in the power transistor, is detected. CONSTITUTION:The input current applied to the base terminal 1 of a power transistor 2 is amplified and the amplified emitter current flows toward an emitter terminal 4 from a collector terminal 3. Most of heat to generate in the power transistor 2 passes through a first metal piece 10, passes through an eutectic solder 12 and is conducted to a second metal piece 11. A temprature sensor 8 detects most of the heat generated in the power transistor 2. When the base terminal 1 is actuated by a signal processing part 9 so that its potential is dropped to the vicinity of that of the emitter terminal 4, the power transistor 2 can be interrupted without breakdown of the transistor.

Title: Heat treatment of semiconductor wafer
Inventor: SADAMORI MASAAKI
IPC: H01L21/225
Filed: 1983-08-29
Abstract: PURPOSE:To prevent semiconductor wafers from generation of mutual adherence when heat treatment is performed putting the semiconductor wafers close mutually by a method wherein the semiconductor wafers are immersed previously in a non-polar solution containing organosilane halide to form organosiloxane films on the surfaces of the wafers. CONSTITUTION:Respective semiconductor wafers 2 are immersed previously in a non-polar solution containing organosilane halide to form organosiloxane films on both the main surfaces of the semiconductor wafers. The wafers 2 completed with pretreatment thereof are transferred onto a boat 3 by tweezers 4 one sheet by one sheet, and arranged in the shape of a stack 2a interposed between end blocks 3a, 3b. Even when the wafers are heat-treated in this condition, thermal decomposition is caused during performance of diffusion heat treatment, extremely scanty carbon powder is generated uniformly on the surfaces of the wafers, and mutual adherence of the wafers is hardly generated owing to the obstruction of carbon powder at the surfaces of the wafers put close mutually.

Abstract: PROBLEM TO BE SOLVED: To provide a ground leakage alarm built-in mold-case circuit breaker capable of supplying current necessary for operating an leakage alarm built-in output circuit and provided with a direct current power source, whose current loss is reduced during its operation. SOLUTION: When earth leakage is generated and an exciting coil of a latching relay 19 is in a current carrying condition, a constant voltage operation is maintened in such a way that a transistor 24 for a current bypass is turned on by a direct current power source circuit 22. At this time, an output current IL, having not less than a minimum operating current ILmin for the relay 19, flows into the relay 19 through bypassing a current detecting resistance 23. After a maximum operating time TLmax for the relay 19 passes, charging of a bias condenser 27 is developed, and the transistor 24 for a current bypass is turned off. Almost at the same time as this a transistor 30 for a limit current is tuned on and a base current for a voltage drop transistor 8 is drawn, whereby output current is limited to the relay 19 to reduce a current loss of the direct current power source circuit 22.

Title: Amplitude frequency characteristic equalizing circuit
Inventor: SHINOZAKI SATORU
IPC: H03H11/04
Filed: 1989-06-23
Abstract: PURPOSE:To eliminate the need for a DC block capacitive element and to attain semiconductor circuit integration by connecting a couple of varactor elements in series in opposite polarity, inserting the elements between emitters of a couple of transistors(TRs) forming a differential amplifier and applying a control voltage to the midpoint. CONSTITUTION:Varactor diodes X1, X2 as a couple of varactor elements are connected in series in opposite polarity are connected between emitter terminals of a couple of TRs Q1, Q2 forming a differential amplifier while a midpoint is provided to the anode side, and a control voltage Vc is applied to the midpoint via an AC blocking resistor R7. Thus, the quantity of equalization compensation depends on the control voltage Vc, the capacitance of the diodes X1, X2 and a resistance of a resistor RT. Thus, the equalization compensation is made variable without giving effect on the bias condition of the other part of the circuit, and the DC blocking large capacitive element is not required, thus the semiconductor circuit integration is attained.

Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To improve the visibility of a driver by coating the centers of a road marking, a center line or a no-passing line with different colors in response to travel-speed control values. SOLUTION: The center of a road is coated with a white center line or no-passing lines 10 while the center of the center line or the no-passing lines 10 is coated with a travel-speed control-value marking line 12 marking travel- speed control values by colors. The travel-speed control value 12 is formed of red at the time of the travel-speed control value of 40 km/h, green at the time of 50 km/h and a sky blue at the time of 60 km/h. The width A of the center line or the no-passing lines 10 is set generally in 0.15 m, but the width B of the travel-speed control-value marking line 12 is set typically in approximately 0.005 m. The travel-speed control-value marking line 12 may be applied simultaneously by adding an each-color coater to an overhead type airless line marker at the time of the application of the center line or the no-passing lines 10.  Accordingly, a driver can recognize the travel-speed control values instantaneously by viewing, and the overlooking of the travel-speed control values is prevented.

Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To surely superpose respective kinds of toner and to restrain the lowering of developing margin by arranging respective developing devices so that the developer may be superposed on a photoreceptor in order from the developer whose rise of re-electrified amount by an electrifier is small. SOLUTION: The respective developing devices 31 to 34 are arranged so that the developer may be superposed on the photoreceptor 1 in order from the developer whose rise of the re-electrified amount by the electrifiers 41 to 44 is small. By superposing the developer on the photoreceptor 1 in order from the developer whose rise of the re-electrified amount by the electrifiers 41 to 44 is small, electric repulsion by Coulomb' s force gets small in the case of development with next developer, so that the developer is surely superposed on the developer pattern whose area is very small. When the rise of the potential of a developer layer formed on the photoreceptor 1 first is small, the developing margin in the case of performing development by shifting to a second color can be taken to be wider.
