Title: Controlling method for chopper
Inventor: KINOSHITA SHIGENORI
IPC: H02M3/135
Filed: 1980-05-15
Abstract: PURPOSE:To stably perform the regenerative braking even at a high speed time by controlling the current flowing angle of a chopper and a branch thyristor in accordance with the output signal of a current controller and limiting a load side current to a low value when the voltage of a power source is decreased. CONSTITUTION:A controlling circuit 26 receives a differential current signal Vi between the motor current and the set current from a setting circuit 24 and controls the current flow rate of a branch thyristor 10 from alphamin to alphamax with the current flow rate of a chopper 14 as alphamin with the signal Vi being in the range of zero to 50% and controls the current flow rate of the chopper 14 from alphamin to alphamax with the current flowrate of the thyristor 10 as alphamax with the Vi being 50 to 100%. The set current value of the circuit 24 is reduced when the voltage of a power source is dropped lower than the set value. Thus, the regenerative braking can be performed in the wide range and can be controlled stably at a high speed.

Title: Position detection system
Inventor: YAZAKI NAOMI
IPC: G07D9/00
Filed: 1990-03-14
Abstract: PURPOSE:To detect a moving body at all times and to detect the position of an arm even if the arm stops for some reason by providing sensors in the movement range of the arm at intervals narrower than the width of the moving body provided to the arm. CONSTITUTION:When the arm 4 moves as shown by an arrow A, all the outputs of the sensors are '0' unless each sensor detects the arm. Further, when the arm 4 moves as shown by the arrow A and a sensor 3 detects a reflecting plate, the output of the sensor 3 rises to '1'. When the arm 4 furthermore moves as shown by the arrow A, a sensor 2 detects the reflecting plate and its output rises to '1'. At this time, if the arm stops for some reason, the outputs of the sensors 2 are both '1', so the outputs of both the sensors are analyzed by firmware, etc., and the stop position of the arm 4 can securely be detected.

IPC: H02P5/00
Filed: 1995-03-23
Abstract: PURPOSE: To prevent abnormality of overcurrent, overload or over-speed, by calculating a difference between motor currents and each current or a load obtained from the current, comparing it with a reference value and generating a blocking signal when the calculated value is above the reference value. CONSTITUTION: Each current signal of motors from current detectors 8a and 8b is entered in an overcurrent/overload comparing circuit 21 or 22 through a terminal 25 or 26 to calculate each state of current and load of upper and lower motors.

Abstract: PURPOSE:To enhance the insulation ability of a sealed terminal by fitting a cylindrical part formed in a cluster attached to a lead wire from a motor element, in the cup-like inner wall of the sealed terminal. CONSTITUTION:A motor element 2 and a compression element which is not shown are disposed in a casing 1. A sealed terminal 3 is fixed to the side wall of the casing 1.

Abstract: PURPOSE:To improve the mask aligning precision, by burying an isolation film in a first groove for providing inter-element isolation. CONSTITUTION:A semiconductor substrate having a masking material which is to be used in subsequent trench etching is provided with grooves 3A and 3B having a predetermined depth. A relatively thin insulation film is deposited thereon and a photoresist mask is formed by mask alignment except for the region where a memory cell capacitor is to be formed.
