Title: Motor control circuit
Inventor: MIZUMOTO MASAO
IPC: H02P29/00
Filed: 1989-11-10
Abstract: PURPOSE:To perform highly accurate rotation control without increasing the number of stage of flip-flop circuit nor the reference clock frequency by synthesizing outputs from a speed control circuit and a phase control circuit through a synthesizing circuit. CONSTITUTION:A speed control circuit 15 outputs a fast or slow signal while a phase control circuit 18 outputs a lead or lag signal in response to the rotation and the speed of a motor. Outputs from the speed control circuit 15 and the phase control circuit 18 are synthesized through a synthesizing circuit 21 under a condition where the output level from the phase control circuit 18 is lower than that from the speed control circuit 15. Since the motor is subjected to phase control after being subjected to speed control according to an output from the synthesizing circuit 21, highly accurate rotation control is realized. It is realized without increasing the number of stage of flip-flop circuit nor the frequency of reference clock CK0.

Title: Heat-developable photosensitive material, and heat developing method
Inventor: FUJIWARA ITSUO
IPC: G03C1/498
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a heat-developable photosensitive material excellent in conveyability in heat development and causing no scratch on the surface of a heating means by holding a matting agent having a specified softening temperature on at least one side of a substrate. SOLUTION: The heat-developable photosensitive material is developed by heating, contains a catalytically active amount of a photosensitive silver halide, a reducing agent, a reducible nonphotosensitive organic silver salt and a binder and has a layer containing a matting agent having 100-500 deg.C softening temperature (softening point) on at least one side of the substrate. Since the matting agent is contained, conveyability (passability) in heat development and such wearing property as to make the surface of a heating means free from a scratch are improved. In the case of <100 deg.C softening temperature of the matting agent, the conveyability deteriorates. In the case of >500 deg.C, the surface of the heating means is liable to have a scratch. The softening temperature is measured by differential scanning calorimetry(DSC) or other method.

Filed: 1985-12-28
Abstract: PURPOSE:To allow a semiconductor device incorporated into a system to stay stable in characteristics without a thermostatic chamber or insulating materials by a method wherein a controlling means is provided capable of governing a heating means based on the output of a temperature detecting means for the semiconductor device to be kept at a constant temperature. CONSTITUTION:In a temperature detecting section 3, a transistor Tr1 and resistors R1-R3 constitute a bridge capable of detecting changes in temperature, outputting signals in potentials or currents reflecting the changes. In a controlling section 4, a differential amplifier amplifies the signals outputted by the bridge, producing changes in a bias voltage applied to the base of a voltage- current transistor Tr4. Accordingly, currents entering a heating section 5 is subject to changes proportional to changes in the signals outputted by the bridge. A heater resistor HR in the heating section 5 generates heat, heating a semiconductor substrate 1 in the vicinity of a semiconductor circuit 2, and the quantity of heat is subject to the intensity of a current inputted into the heater resistor HR. As the result, the semiconductor substrate 1 is heated less upon a smaller signal out of the temperature-detecting section 3, and more upon a stronger signal out of the same.

The characteristic changing circuit 20 comprises a transistor (TR4) whose base is connected between voltage dividing resistors R5 and R6 and a switching transistor TR2 for providing voltage dividing resistors R7 and R8 and a second resistance R2 in addition to the first resistance R1. In this way, upon starting of the power supply, a rush current is limited because a starting characteristic of the stabilizating circuit 10 is determined by the first resistance R1. After a signal is outputted from the signal generation circuit 30. The follow-up characteristic of load fluctuation is improved by provision of the second resistance R2.
