Abstract: PURPOSE:To open a vacuum circuit breaker near the zero-current point twice in one cycle in either one phase, interrupt a large current, and suppress the occurrence of surges by opening the vacuum circuit breaker while individual phases are drifted by the preset phase angle when the vacuum circuit breaker is opened. CONSTITUTION:When a trip signal is inputted while a vacuum circuit breaker is closed, a motor is activated, and a cam 9 is rotated clockwise. A roller 10a is moved by the rotation of the cam 9 from the position hooked by a tip hook section 92 to the position hooked by a step section 91. The moving shaft 6 of a vacuum valve 4 is moved downward via a link 10, an action rod 11 and a wipe spring 12 to open contacts while the roller 10a is moved from the tip to the step section. Cams 9a, 9b, 9c of individual phases are displaced by the preset angle and fitted to a main shaft 8, and the vacuum valves of individual phases are displaced by the preset phase angle and opened when a vacuum circuit breaker is opened.

Title: Transmission control system for facsimile equipment
Inventor: KOBAYASHI MASAHISA
IPC: H04N1/00
Filed: 1993-07-22
Abstract: PURPOSE:To reduce a fault detection time by allowing a receiver to return a reply signal representing normal operation, faulty operation and state of processing after the reception of a control signal from a transmitter so as to allow the transmitter to monitor the receiver. CONSTITUTION:Upon the receipt of a control signal from a transmitter 1, a section 2a of a receiver 2 sets a predetermined value to a timer 2b, which is started. When a processing end of an operation fault is detected through input output ports (PIO) 2a-4,2a-5 during processing of the procedure corresponding to the control signal, a reply signal representing the processing end or fault is returned. When the timer 2b expires, the timer 2b interrupts a CPU 2a-1 and when no fault is detected, the reply signal representing the processing state is returned. Through the constitution above, the transmitter 1 monitors the state of the receiver 2 for a predetermined time and a fault is detected in a shorter time from the fault occurrence point of time to confirm it.

Title: Thin-film magnetic head
Inventor: NAKAJIMA HIROMI
IPC: G11B5/31
Filed: 1989-07-13
Abstract: PURPOSE:To improve recording/reproducing efficiency by forming the head to a shape enclosed of two arcs, two angles and the straight line connecting these arcs and angles and specifying the angle formed by the tangent of the side face spreading to the arc shape from the pole part thereof and the virtual line parallel with the sliding surface at the front end of the pole part in the neck part of the pole part to about 30 deg.. CONSTITUTION:The upper core 10 of the thin-film magnetic head M2 has a battledore shape and both side faces of the tapered part T spreading from the root of the pole part P thereof are formed to the arc shape. The angle theta2 formed by the tangent S in the part spreading from the root part thereof and the line L1 perpendicular to the longitudinal direction of the pole part P is formed at 30 deg. and the angle part (the part shown by the circle of a broken line) of the core 9 is arced. The reason for forming the angle theta2 at 30 deg. lies in that, while the reproduced output increases with a decrease in this value, crosstalks are of problem and, therefore, the above-mentioned angle is set to obtain the reproduced output of the highest efficiency.

Title: Amplifier circuit and semiconductor integrated circuit including the same
Inventor: JIYON EMU KUURII
IPC: H03F3/30
Filed: 1990-07-10
Abstract: PURPOSE: To enable a class AB operation by inputting by the high voltage gain stage of an amplifier circuit and sufficiently adjusting a zero input current at the buffer stage of a low impedance. CONSTITUTION: The buffer stage 20 of a low impedance is given voltage V1 and V2 by a high voltage gain stage 10. As operation amplifiers (A)1 and (A)2 is not proof against the large change of voltage given to between positive and negative input terminals as the buffer stage 20, feedback to a positive input terminal given by a node N1 between a resistor R1 and a transistor (M)1 and a node N2 between R2 and M2 generates a clearly controlled zero input current iQ which is adjustable to a desired value by the right selection of a parameter. Thereby stable operation with sufficient zero input current iQ is secured to secure the class AB operation.

Title: Flasher for vehicle
Inventor: ISHIDA TOSHIO
IPC: B60Q1/38
Filed: 1987-07-20
Abstract: PURPOSE:To prevent chattering phenomenon in contact by connecting a bypass means, which is conducted when a voltage drop value, generated in a current oil, increases to a preset value or more, in parallel with the current coil of a relay in a flasher circuit. CONSTITUTION:When a selector switch 4 is closed to either right or left, an electric current is allowed to flow in lamps L in either right or left, but by the magnetomotive force of a current coil 6, a normally closed contact 71 of a relay 7 is opened. While simultaneously charging a capacitor 8, by this charging current, the magnetomotive force is generated in a voltage oil 9, holding the normally closed contact 71 to be opened. Next, decreasing the charging current, when the normally closed contact 71 is closed, a lamp current is allowed to flow in the current coil 6, and the lamp L is intermittently turned on by discharging the capacitor 8. Generating a voltage drop in the current coil 6, when a value of the voltage drop reaches the conduction voltage of a diode 10 serving as the bypass means, the diode 10 is conducted, preventing the generation of excessively large magnetomotive force in the current coil 6.

Title: Manufacture of electromagnetic fuel injection valve
Inventor: SUGIYAMA KOICHI
IPC: F02M51/06
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To improve valve density at a low cost. SOLUTION: After a fuel injection valve is assembled as a finished product, a valve needle 30 is operated so that a projected part 33 formed in the vicinity of the abutting part 31 of the valve needle 30 and the valve seat part 21 of a nozzle body 20 repeat collision. Therefore, the projected part 33 is deformed, and the shape of the projected part 33 can fit to the shape of the valve seat part 21. Thus, valve density between the abutting part 31 and the valve seat part 21 can be improved, and fuel leakage at the time of valve closing can be prevented. By the operation only of the valve needle 30 after the fuel injection valve is assembled, the projected part 33 is deformed and valve density between the abutting part 31 and the valve seat part 21 is improved.  Since machining accuracy of each member of the fuel injection valve is not required to be improved more than the conventional case, machining can be facilitated and a manufacturing cost can be reduced.
