Patent JP-H03285583-A (JP)
Title: Brake control circuit for motor
Inventor: OKADA TADASHI
IPC: H02P3/18
Filed: 1990-03-30
Abstract: PURPOSE:To simplify a construction by a method wherein the rotation of a motor is braked by impressing a backward torque on the motor according to a motor stop signal, a DC current is made to flow through a prescribed winding of the motor after a prescribed time passes, and by generating thereby a force of stopping the motor at a prescribed position is generated. CONSTITUTION:When a stop instruction is given at the time t1 when a motor rotates in a rated state, a control circuit 9 with a timer controls a DC inversion switch 8 immediately, so as to invert the direction of a current of Hall elements 4 to 6. Therefore a Hall voltage with an inverted sign is generated and inputted to a motor driver 2. The driver 2 supplies a backward current to the motor and makes a backward torque generated therein. After a prescribed time passes, the control circuit 9 with the timer stops generation of the backward torque. For instance, the current inversion switch 8 is made neutral and the Hall elements 4 to 6 are cut off from a current source 7. Then, a direct current is supplied to a prescribed coil and the motor is stopped at a prescribed position.

Title: Differential amplifying circuit
Inventor: HONMA YASUAKI
IPC: H03F3/45
Filed: 1982-05-21
Abstract: PURPOSE:To improve the high frequency characteristics of a differential amplifying circuit, by using two base-earthed amplifying circuits consisting of a transistor TR and a load resistance respectively. CONSTITUTION:Two base-earthed amplifying circuits are formed with TR1 and TR2 and load resistances 5 and 6 respectively. The base terminals of these two amplifying circuits are used in common with each other, and the current flowing through the common base terminal is set at a constant level. Therefore the sum is constant for the collector currents of the TR1 and TR2. Thus it is possible to amplify the difference between input voltages applied to input terminals 3 and 4. This increases the band width with high gain for a differential amplifying circuit. This circuit contains a constant current circuit A' and plus and minus power supply terminals B and C respectively.

Abstract: PURPOSE:To obtain a polyimide stretched film suitable as an endless belt for precise driving by improving creep characteristics ad thermal dimensional stability by a method wherein the polyimide film comprised by stretching has creep and a thermal shrinkage factor of not exceeding specific values. CONSTITUTION:A polyimide film becomes a polyimide stretched film which is satisfiable sufficiently even as a precise driving belt by a method wherein stress remaining within the polyimide film in removed at the time of stretching, creep is more to fall within 1% and a thermal shrinkage factor is controlled not exceeding 10%.

Title: Deodorization of polyolefin
Inventor: ANNEN YOSHIAKI
IPC: C08J3/00
Filed: 1984-05-01
Abstract: PURPOSE:To obtain a polyolefin substantially free of residual odor, by treating an odoriferous polyolefin with a gas or its mixture with steam in a specified temperature range. CONSTITUTION:An odoriferous polyolefin is treated with a gas or its mixture with steam at a temperature in the range of 60 deg.C - the softening point of the polymer. By deodorization at 80 deg.C, it is only possible to remove 40% of hexanes (HX) and 20% of esters (RY) from odoriferous polyethylene pellets, but the percentage of removal increases with an increase in the temperature, and reaches the maximum at 100 deg.C. When the temperature is further raised, the percentage of removal decreases again. The maximum percentage of removal is 97.8% for HX and 98.8% for RY. For a common purpose, the temperature is set at 98- 128 deg.C, preferably 105-127 deg.C. No criticality appears between the deodorization effect and the flow rate of a gas, especially, air and/or the flow rate of steam.
