Title: Frequency control method for voltage-type inverter
Inventor: TOMITA HIROO
IPC: H02P3/18
Filed: 1980-03-19
Abstract: PURPOSE:To suppress an increase of a DC circuit voltage at time of regenerative action by actuating a DC circuit voltage on an inverter and correcting an inverter frequency based on the said detection in such direction that an electric motor slip may be minimized. CONSTITUTION:When an induction motor 2 is driven by means of a voltage on a DC circuit 1-D for an inverter is detected by a detection means 3 consisting of a proportional integrator which integrates a differential between the said voltage and a reference voltage. Then an output from the said detection means is input to a correction means 4 consisting of an adder which adds a frequency command value and an output voltage of the detection means 3, controlling a frequency for the inverter 1 through a voltage-frequency converter 5. Consequently, it is possible to minimize a slip of an electric motor 2 through the increasing of an interver frequency when a voltage has increased following the return of a regenerative power to DC circuit 1-D side at time of a regenerative action. Thus an overvoltage can be prevented effectively.

Title: Power supply application method of electronic device
Inventor: ICHIKAWA KOUJI
IPC: G06F11/00
Filed: 1981-03-11
Abstract: PURPOSE:To detect a fault of a circuit, by having a short circuit between the prescribed two connecting terminals among plural component elements and at the same time, measuring the resistance value of a loop in which a different resistance is inserted between the corresponding terminals at the side of a device to which the component elements are incorporated. CONSTITUTION:The print panel units 1-4 functioning as plural component elements are short-circuited between the desired connecting terminals 5 and 6, for example. For the connector at the side of an electronic device, a checking loop 7 is formed in correspondence to the terminals 5 and 6 of the short-circuited print panel units. The resistances 8-11 having different values are connected to the loop 7 in correspondence to the units 1-4. When a power supply is applied to the electronic device, a faint current is flowed first to the loop 7 to measure the resistance between the measuring terminals 14 and 15. The measured value reads zero in case the units 1-4 are all inserted in a correct way. If just one fault exists, the corresponding resistance value emerges. In such a way, an erroneous insertion of the print panel can be previously detected to prevent the breakage of a circuit.

Title: Brake structure for linear actuator
Inventor: KUMAGAI TAKASHI
IPC: H02K7/06
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To eliminate a brake structure on the motor side by abutting a bend of a leaf spring provided on a base body against a recess in a movable part, thereby braking the movable part. SOLUTION: A recess 4A in a movable part 4 is engaged with a bend 7a of a second leaf spring 7, and the movable part 4 is stopped at the right end side of a base body 1. When a screw shaft 2 is rotary driven through a drive means 3 under such a state, the recess 4A is disengaged and moved to the left side. When the screw shaft 2 is turned furthermore in the same direction, the movable side is moved to the left side and the recess 4A engages with the bend 6a of a first leaf spring 6. Consequently, stopping and positioning take place simultaneously upon braking the movable part 4. Since the other end 6B, 7B of the leaf spring 6, 7 are engaged with a fixing screw 10, 11 through an elongated hole, deformation of the leaf spring 6, 7 is increased, and engagement of the recess 4A and the bend 6a, 7a is made smooth, thus making smooth the brake action of the movable part 4.  Since no brake means is required on the side of motor for turning the screw shaft 2, motor cost can be reduced significantly.

Title: Control system for reactive power compensating device
Inventor: MURABAYASHI KAZUHIKO
IPC: H02J3/18
Filed: 1981-03-16
Abstract: PURPOSE:To achieve operation with low loss, by fixing a reactive power generated from a thyristor controlling reactor at a temporary stop of an arc furnace to as small value as possible within a permissible range of increase in a system voltage. CONSTITUTION:During the opertion of an arc furnace 1, a control circuit 5 calculates a reactive power QF generated from the arc furnace and a reactive power by a branch reactor 3 for the compensation of a reactive power Qc by a fixed capacitor 2 and converts them into a position controlling signal Ec. The signal Ec is applied to a thyristor converter 4 and a trigger angle of the converter 4 is controlled to generate the power QL required for compensation. When the arc furnace is temporarily stopped, an arc furnace stop detecting circuit 6 gives an arc furnace stop signal 15 to the circuit 5, which receives the signal and controls the trigger angle of a converter 15 to a prescribed trigger angle larger than the minimum trigger angle and at a permissible limit of the rise in the system voltage. Thus, the generated loss of the reactor 3 can be reduced without opening the power supply to the reactor 3 and the compensation operation can immediately be restarted when the arc furnace restarts the operation.
