Title: Integrated pressure sensor
Inventor: YAMADA KAZUJI
IPC: G01L9/00
Filed: 1983-05-31
Abstract: PURPOSE:To obtain the titled device processed to an integrated circuit which automatically compensates the temperature by a method wherein the thin part of a nearly square Si chip whose center is thin and whose outer periphery surrounding it is thick is provided with a plurality of gauge resistors, signal processing circuit being formed in the thick part, and this chip is fixed on an Si base having a pressure introduction port at the center by means of a thin film which can be brought to electrostatic coupling. CONSTITUTION:A plurality of the gauge resistors 10a-10d are diffusion-formed in the thin part serving as the diaphragm 11 of the Si chip 7 whose center is thin and whose outer periphery surrounding it is thick, and the thick part surrounding the resistors is provided with the signal processing circuit 12. Next, the part opposed to the diaphragm 11 is provided with the Si base 8 having the pressure introduction port 13, which is then adhered to the back surface of the chip 7 by means of the thin film 9 about 4mum thick which can be brought to electrostatic coupling. Here, borosilicate glass or the like is used for the thin film 9, which film is coupled to the chip 7 and the base 8 by impressing a voltage while the temperature is kept at about 400 deg.C. When the chip 7 is thus supported with the base 8, the change of characteristics due to thermal stress is prevented.

Title: Electrostatic charging device
Inventor: KISU HIROKI
IPC: G03G15/02
Filed: 1988-04-20
Abstract: PURPOSE:To prevent a leak to a body to be charged electrostatically and to perform uniform, stable electrostatic charging without causing any defect in electrostatic charging even if an electrostatic charging member varies in resistance and capacity owing to a change in environmental condition by applying a voltage generated by superposing an AC and a DC component and controlling the AC component to a specific constant current value. CONSTITUTION:The blade type electrostatic charging member 4' which has a surface layer 4c'of epichlorohydrin rubber, etc., on the surface of a blade 4b' is applied with a voltage from the power source E consisting of an AC power source E-1 controlled by an AC constant current control means G so as to supply an invariably prescribed current and a DC power source E-2 controlled by a DC constant voltage control means H so as to apply an invariably prescribed voltage. Thus, the electrostatic charging member 4 which abuts on the body 3 to be charged is applied with the voltage which has the AC and DC components to uniform the surface potential of the body 3 to be charged. Further, the AC component is controlled to the prescribed constant current value to prevent a leak to the body to be charged and performs the stable electrostatic charging without causing any defect in electrostatic charging even if the electrostatic charging member varies in impedance owing to the change in environmental condition.

Filed: 1979-07-31
Abstract: PURPOSE: To add the additional processor without giving a big modification to the existing system, by connecting both the data processor CPU and the additional processor to the main memory unit via the interface switching unit.  
     CONSTITUTION: Interface switching unit 6 is provided between main memory device 1 and CPU2. Unit 6 is connected to CPU2 via bus 8 and AA signal line 10; and also unit 6 is connected to additional processor 3 via bus 9 plus AA line 11 respectively. And the switching of unit 6 is carried out by controlling CPU3. In case logic 0 is given to line 10, the information is transferred between device 1 and CPU2. And when line 10 is in logic 1, the information is transferred between CPU2 and processor 3. And if logic 0 is applied to line 11, the information is transferred between device 1 and processor 3. In case line 11 is in logic 1, the information is transferred between processor 3 and CPU2. Thus the addition of processor 3 just means the addition of the AA line for the existing unit.

Filed: 1994-05-11
Abstract: PURPOSE:To enhance heat exchange efficiency by controlling direction of passing air and sprayed water by arranging a water/air guiding means in a serpentine piping block having a network construction which the water and air are allowed to pass through. CONSTITUTION:In a heat exchanger, blocks 2 constituted of serpentine pipes arranged in close contact with each other are disposed in layers with evaporation heat exchanger filling material 3 with outlet side thereof being at an elevated position so that fluid in the serpentine pipes is allowed to flow in meander by means of U-shaped bent pipes provided at pipe ends from air outlet side to air inlet side. Because the serpentine pipes have an inclination formed by disposing the air outlet side thereof at an lower position, good draining can be performed. Within the blocks 2, matter to be cooled is made to flow from a header 1 in a counterflow direction of passing air (A). Guiding nets 10 are inserted at both the air inlet and air outlet sides in each of the blocks. The introduced air (A) passes through the interior of the blocks of each layer and is discharged by a fan 4. Sprayed water for cooling moves through the evaporation heat exchanger filling material 3 and the blocks 2, and is circulated for use.

Title: Control device for switch
Inventor: YAMADA KAZUO
IPC: H02H3/05
Filed: 1989-04-18
Abstract: PURPOSE:To control a switch with precision by finding a corrected value into memory if the frequency of a signal inputted from a test signal generator to a filter in a test slips off at not less than a designated value and by amending it with the corrected value in the actual monitoring. CONSTITUTION:When switches 6 for testing are manually operated, a test signal generation circuit 9 generates signals IO, VO and phi of the quantity of electricity for testing and inputs them into test switching circuits 23 and 33. The signals for testing are filtered 24 and 34, smoothed 25 and 35 to effective values, converted 26 and 36 in levels and inputted into a CPU 4. When the frequency slips off owing to the fluctuation of characteristic of filters 24 and 34, corrected values are operated in comparison with the outputs of a setting circuit 5 and stored into the CPU 4. When zero-phase-sequence current 2 or zero-phase- sequence voltage 3 of a power supply system 1 is monitored, it is decided whether or not the values are at not less than the setting to control the switches. Precise switch control can thereby be performed even if the characteristic of filters are slipped off.
