Title: Electric controller for injection pump
Inventor: ITOU OSAMU
IPC: F02D41/40
Filed: 1980-12-09
Abstract: PURPOSE: To perform reliable fuel injection control in an electro-magnetic actuator for operating an injection pump by disposing a fixed core with an exciting coil around a movable core.  
     CONSTITUTION: A fuel supply pump 12 is turned by a drive shaft 11 to supply a fuel for a pump housing 13. The fuel is squeezed to an injection nozzle 6 through a suction hole 18, a compression chamber 17 and an outlet hole 19. An effective stroke of a plunger 12 depends on positions of a spill ring 22, which is controlled by a rotary core type actuator 3. A fixed core 33 with an exciting coil 34 is disposed around a movable core 32 and provided with a spring 35 which generates a restoring torque. Because only the exciting coil 34 around the fixed core 33 has to be fed with a current, reliable fuel injection control may be performed.

Title: Wire-cut electric discharge device
Inventor: INOUE KIYOSHI
IPC: B23H7/04
Filed: 1983-09-22
Abstract: PURPOSE:To improve the averaged linearity of a wire electrode between guides for positioning to enhance the stability of machining, by inducing electro-magnetic repulsive force between the wire electrode and a workpiece with the use of pulse discharge current for machining which is applied to the wire electrode and the workpiece. CONSTITUTION:By alternately changing over conductor pins 25, 26 by means of a switch 27 the negative polarity of an electrical pulse power source 2 is applied to a wire electrode 7 while the positive polarity of the power source 29 is applied to a workpiece 14 from a change-over switch 27' through gears 35 and contacts 36 to which brushes 44 are contacted. Discharge current is fed from the positive pole of the power source 29 to the workpiece 14 through one or both of the brushes 44, and the contacts 36, and thereafter reaches to the negative pole of the power source 29 through a discharge point in an electric discharge gap, the electrode 7 and one or both of the pins 25, 26. By changing electrical potentials applied to the pins 25, 26 and to the workpiece 14, and as well by reciprocatingly rotating the contacts 36 always with the use of servo-motors 39 to displace a certain area in the direction of advancing about the electrode 7 as a center in order to randomly induce repulsive forces, the displacement due to repulsive forces by electric discharge is disturbed to averge forces repelling to each other thereby a flection of the elctrode 7 is corrected.

Title: Method and circuit for limiting overcurrent using mosfet switch
Inventor: HATTORI TAKAHIRO
IPC: H02H3/08
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To gradually limit an overcurrent without cutting off the the overcurrent immediately by switching to by-passes by outputting a flag by connecting two MOSFET switches having different 'ON' resistances in parallel with the current path of a high-side switch when the overcurrent is detected. SOLUTION: The P-channel MOSFETs of switches 1 and 2 having different 'ON' resistances are connected in parallel. A D/A output 5 which makes analog output operation is connected to the gate of the MOSFET of the switch 1 having the lower 'ON' resistance. The value of the current flowing to the switch 1 is detected with a delay time of >=10 μs. When an overcurrent detecting means 3 detects that the current flowing to the switch 1 for >=10 μs is an overcurrent, a current limiting means 4 finally sets the switch 1 to a turned-off state (infinite resistance value) by increasing the resistance of the switch 1 by gradually changing the gate voltage of the MOSFET of the switch 1 to the voltage of an input 7 from 0 V. In addition, the means 4 turns on the MOSFET of the switch 2 having the higher 'ON' resistance.

Title: Anaerobic wastewater treatment equipment
Inventor: ITO SATORU
IPC: C02F3/28
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To enable stable operation by making it possible to return a part of the treated water in a treated water tank to both of a pH adjusting tank and an anaerobic wastewater treatment apparatus by a circulating pump. SOLUTION: A part of treated water is returned to the piping between a liquid supply pump 2 and an anaerobic wastewater treatment apparatus 3 (small circulating system) as circulating water. The setting of the operation method and flow rate of a circulating pump 5 is different by a circulating system and, in a large circulating system, the circulating pump 5 is stopped when the water level of a pH adjusting tank 1 is high and the water level of a treated water tank 4 is low. Herein, since a small circulating system is employed at a usual time and the circulating pump 5 is continuously operated, a freezing measure and the intermittent operation of a circulating line being the defects of the large circulating system are eliminated.  Since a measure for adjusting the pH and temp. in the anaerobic wastewater treatment apparatus 3 due to trouble being the defect of the small circulating system can be taken by changing over the small circulating system to the large circulating system returning treated water to the pH adjusting tank 1 and adjusting the temp. and pH of treated water, a wastewater treatment plant can be stably operated.

Abstract: PURPOSE:To provide a 1.5V class organic electrolytic lithium cell having the voltage flatness and the high temperature stock performance, by employing an oxy-salt bismuth as a positive pole active substance. CONSTITUTION:(A) is a cell where an oxy-salt bismuth is employed as a positive pole active substance, (B) is a cell employing an iron sulfide, (C) is a cell employing a bismuth oxide, (D) is a cell employing a tetraoxide lead while (E) is a cell employing a copper oxide. As apparent from an drawing, the characteristic where each cell is discharged with the constant current of 200muA under the temperature of 20 deg.C is such that the cell (E) will show the longest holding time but the discharging voltage is as low as 1.40. The cells (B) and (D) will  show the voltage characteristic similar to the conventional water solution system  cell. Cell (C) will show the two step discharging curve. Cell (A) is employing a  bismuth system compound but has a flat voltage characteristic and the holding time is not inferior when compared with other cell system. When stocking the  same cell for one month under the temperature of 60 deg.C and discharging with the  constant current of 200muA under the temperature of 20 deg.C, the characteristic is  never deteriorated except that the voltage will drop slightly at the initial discharging stage.

Filed: 1987-07-14
Abstract: PURPOSE:To restrictively lower the height of a magnetic head and to enable its stable moment by making the width of a gimbal spring and a carrier part for supporting this gimbal spring narrower than the width of an opening on a cartridge surface. CONSTITUTION:The titled magnetic head mechanism 30 is constituted integrally with a rack gear which is driven via a pinion gear 31, and the recording and reproducing are carried out by driving and scanning the magnetic heads 33 and 36 along the radial direction of a magnetic disk 12 inside the opening part 13 formed on the cartridge surface. The width W1 of the gimbal spring 39 for supporting the magnetic head 36 above the upper surface of the magnetic disk 12 freely oscillative to the carriage 35 is formed as narrower than the width W of the opening part 13. Consequently, there is no fear of abutting the gimbal spring 39 against the cartridge 11, without detriment to the degree of freedom of the oscillation, a vertical displacement of the magnetic head 36 caused by waving deflection of the magnetic disk 12 due to a warp can be absorbed.
