Title: Delay synthesizing circuit
Inventor: SUGIE KIYOKAZU
IPC: H03H11/26
Filed: 1985-04-10
Abstract: PURPOSE:To obtain a delay synthesizing circuit of a constant gain, by controlling the attenuator of the output part of the delay synthesizing circuit in accordance with the difference between the input signal level to the circuit and the level of the signal in a delay synthesizing loop. CONSTITUTION:One side of signals impressed upon a delay synthesizing circuit is impressed upon an input detector 7 by means of a distributor 2 and the other side is impressed upon a delay synthesizing loop through an input coupler 3.

Title: Automatic control device for polishing amount of metal plate
Inventor: AKAI TOSHIO
IPC: B24B49/16
Filed: 1983-05-02
Abstract: PURPOSE:To prevent polishing unevenness from being produced by successively monitoring a load current of a polishing member turning motor and controlling a pressure adjusting motor such that its difference from a set load current is zero. CONSTITUTION:When a load current in responce to the thickness of a metal plate 14 to be polished is set to a load current setter 24, a signal comparator 26 compares this with an ordinary load current, and issues a signal to a pressure control device 22 to drive a pressure adjusting motor 10, allowing pressure to be adjusted to that responsive to the thickness. And, a polishing member 12 is turned in a state where a rotation control device 18 controls the driving of a turning motor 8, allowing the metal plate 14 to be polished. Namely, during the polishing, the control device 18 monitors a load current of the motor 8, and sends a signal to the comparator 26, which comparator 26 evaluates a difference between a set value from the setter 24 and the load current of the motor 8, thus allowing the pressure control motor 10 to be controlled by said signal via the pressure control device 22. In such a way, the polishing amount per unit time can be made constant irrespective of the shape of the metal plate.

Filed: 1990-03-27
Abstract: PURPOSE:To easily manufacture this laser whose reliability and performance are high by a method wherein a ternary or higher III-V compound mixed crystal in which the bonding length between group III atoms and group V atoms is different from each other in crystals is used as an active layer and only a part near the reflection edge or the radiation edge of a beam is doped with a prescribed or larger amount of impurities which make the resistance of a semiconductor layer high. CONSTITUTION:A ternary or higher III-V compound mixed crystal in which the bonding length between group III atoms and group V atoms is different from each other in crystals is used as an active layer 3. Only parts near edges 8 used as reflection faces or radiation faces of a beam in the active layer 3 are doped with impurities of about 5X10<-17>cm<-3> or lager amount to make a resistance high. The beam is not absorbed at window parts near the edges whose Eg is large; it is possible to prevent the damage of the beam and the deterioration at the edges. Since the window parts are high-resistance insulating regions, an electric current is concentrated efficiently in the regions which give a laser gain. As a result, a semiconductor laser whose reliability and output are high can be realized by an easy manufacturing method.
