Patent JP-H04172991-A (JP)
Title: Current control circuit
Inventor: MORITA SHIGEKI
IPC: H02P7/29
Filed: 1990-11-01
Abstract: PURPOSE:To always maintain a predetermined average current by comparing the maximum value of an output current with a voltage obtained by smoothing an input pulse, and controlling ON, OFF a transistor for driving the coil of an actuator based on the compared result. CONSTITUTION:The time of the ON state of a power transistor 2 can be regulated by the time constant of CR of a smoothing unit 14. If the time constant of the CR is large, correction of the time of ON state is increased, and the average value is increased when a power source voltage is low as compared with the case that the power source voltage is high. If the time constant of the CR is suitable, correction of the time of the ON state is suitable, and the average current becomes constant irrespective of the power source voltage. If the time constant of the CR is low, the correction of the time of the ON state is small, and the average current becomes lower when the power source voltage is low as compared with the case that the power source voltage is high. Even if the resistance of the coil 3 of an actuator is varied so that the rise of the current is delayed, similar correction is conducted to hold the average current constant.

Title: Power source stabilizing circuit
Inventor: SATO TETSUO
IPC: G05F1/56
Filed: 1986-12-17
Abstract: PURPOSE:To improve a voltage reducing characteristic, by providing a voltage follower which compares, a reference voltage with an output voltage, and performs a stabilizing operation by driving a control element. CONSTITUTION:The voltage follower is constituted with transistors Q2 and Q3 and a resistor R2. A controlling transistor is constituted of a PNP transistor Q1, and a free running voltage Ve is supplied to the emitter that is an input terminal, and the output voltage can be obtained from the collector that is an output terminal. And by returning the output voltage to the first input terminal of the voltage follower, the controlling transistor Q1 is controlled by an output signal compared with the reference voltage Va. When the level of the free running voltage Ve is higher than that of the reference voltage Va, the level of the output voltage is controlled at that of the reference voltage Va by the operation of the voltage follower. And when the free running voltage Ve is less than the reference voltage Va and exceeds the voltage between the base and the emitter of the transistors Q2 and Q3 consisting of the voltage follower, the controlling transistor Q1 is saturated, and the free running voltage Ve goes to the output voltage, and the voltage drop of its own power source stabilizing circuit itself can be blocked.

IPC: H01L21/20
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To form a polycrystalline silicon film of good film property on a substrate of low-melting-point glass or the like. SOLUTION: A silica-based porous film 12, having fine pores only in the film inside, is formed on a quartz substrate 10 which is a high-melting point material. After the porous film 12 is formed, an amorphous or polycrystalline silicon film 14 is formed on the film 12, and is subjected to heat treatment at a high temperature to polycrystallize the silicon film by growing its crystalline grain size large and uniform to form a polycrystalline film 16, yielding a transfer mother material. Then, on a surface of a low-melting point glass substrate 20, which is a substrate to be transferred, the transfer mother material is so arranged as to touch the surface of the polycrystalline silicon film 16 to join the polycrystalline silicon film 16 and the glass substrate 20, and the joined body is immersed in a hydrofluoric acid solution, which is an etchant.  Since the porous film 12 is most rapidly etched by hydrofluoric acid, the polycrystalline silicon film 16 is peeled off from the quartz substrate 10 of the mother material and is left on the glass substrate 20. As a result, the polycrystalline film 16 of satisfactory film property obtained by the heat treatment is transferred on the glass substrate 20.
