Title: Speed control circuit for dc motor
Inventor: KOMINAMI YASUO
IPC: H02P7/288
Filed: 1979-11-30
Abstract: PURPOSE:To prevent the error due to the temperature change in the speed control circuit for the DC motor whose driving current is controlled by a current mirror circuit, by driving the current mirror circuit with the emitter follower of an NPN transistor. CONSTITUTION:A reference voltage is applied to one input of a voltage comparating circuit 12 constituted by transistors Q4, Q5, Q6, and Q7, and the output voltage of the current mirror circuit 16 is fedback to the other input thereof, thereby the counter-electromotive force of the DC motor 10 gets a constant voltage, and the motor is driven at a constant rotational speed. A transistor Q1 which drives the current mirror circuit 16 is driven by the emitter follower of the NPN transistor Q9 which responds to the output signal of the voltage comparing circuit 12. Since the NPN transistor Q9 has a high current amplification factor, the base current of Q1 becomes small, thereby the error due to the temperature change can be minimized.

Title: Laser diode drive circuit
Inventor: IRIE HIRONORI
IPC: H04B10/07
Filed: 1989-06-19
Abstract: PURPOSE:To prevent the generation of excessive current, deterioration and breakdown of a diode by installing a protective circuit to the output of an error amplifier. CONSTITUTION:A laser diode 1, a monitor PD, an error amplifier 2, a protective circuit 3, and a bias current generation circuit 4 constitute a negative feedback loop and operate so that the light output of the laser diode may be constant. As negative feedback control is not exercised while the power is supplied, the output voltage 20 of the error amplifier 2 may exceed an optimum value. The protective circuit 30 protects bias current control voltage 30 so that it may not exceed the optimum value even when output voltage 20 rises rapidly, thereby preventing excessive bias current from flowing to the laser diode 1. It is, therefore, possible to prevent excessive electric current from being supplied to the laser diode 1 and to protects the laser diode 1 against its deterioration and breakdown as well.

Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To obtain a rail excellent in wear resistance and ductility by using steel contg. C, Si, Mn and Nb in a specified ratio and P and S of a specified valve or below. SOLUTION: This pearlitic steel rail contains, by weight, 0.75 to 0.84% C, 0.1 to 1% Si, 0.4 to 2.5% Mn, <=0.035% P, <=0.035% S and 0.05 to 0.5% Nb. The C is an essential element for securing its wear resistance. The Si is a deoxidizing material. Mn reduces the pearlitic transformation temp., and makes the lamellar intervals in the pearlitic structure very small, then contributes to increase the strength and ductility of the rail. The Nb is bonded with C in the steel, is finely precipitated as carbide after hot rolling, increases the hardness to the inside of the head of the rail by precipitation strengthening, improves its wear resistance and contributes to prolong the life of the rail. It is also preferable that the rail is incorporated with <=1.5% Cr, <=1% Cu, <=1% Ni and <=1% Mo, to more increase its strength by solid solution strengthening.

Filed: 1989-06-16
Abstract: PURPOSE:To reduce a running cost and to increase the lifetime of a circulation pump by providing a circulation pump to be switched at hot water flow rates to a plurality of stages and a controller for intermittently switching the pump at strong-weak operation. CONSTITUTION:A combustion controller 16 and a pump controller 17 start operating upon closing of an operation switch 11. The controller 16 turns a burner 2 'ON' 2a and 'OFF' 2b in response to the detection temperature 10a of a hot water temperature thermostat 10. The controller 17 repeats to forcibly turn a circulation pump 4 'strong' 4a for predetermined time t1 and to then forcibly turn it 'weak' 4b up to time t2, thereby intermittently operating it. The periods and conducting times of the 'strong', 'weak' can be switched by a manual switch 15. According to this, the operating time in the 'strong' of the pump is shortened to conserve power. Since a rotating speed is reduced at the time of the 'weak' operation, the lifetime of the pump is increased.
