Filed: 1992-09-01
Abstract: PURPOSE:To inhibit a noise, which is induced by return light, even if the amount of the return light is increased by a method wherein an active layer having a quantum well layer and a barrier layer adjacent to this quantum well layer is provided on a substrate and insulating films, which respectively have specified reflectance, are respectively provided on the end face on one side of one pair of light output end faces and on the other end face. CONSTITUTION:An insulating film 116 consisting of three layers of an Al2O3 dielectric film, an Si film and an Al2O3 dielectric film, which are laminated in the order of these Al2O3, Si and Al2O3 films, is formed on the surface of a semiconductor window layer 114 on the end face on one side pair of light output end faces of a semiconductor laser element. On the other hand, an insulating film 117 consisting of five layers of an Al2O3 dielectric film, an Si film, an Al2O3 dielectric film, an Si film and an Al2O3 dielectric film, which are laminated in the order of these Al2O3, Si, Al2O3, Si and Al2O3 films, is formed on the surface of a semiconductor window layer 115 on the other end face on the opposite side to the end face. A reflectance on the side of the film 116 is set so as to become a reflectance of 20% or higher and a reflectance on the side of the film 117 is set at 60% or higher. Thereby, a laser beam emitted from the semiconductor laser element is prevented from being coupled with return light reflected by an optical disc or the like and a noise is reduced.

Title: Maximum power control method for solar battery
Inventor: KOSHIN HIROAKI
IPC: G05F1/67
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To highly accurately execute maximum power control by changing a current command value so as to perform the control at a point where a fixed voltage is added to the operating point voltage at the point of time when output power from a solar battery is not increasing and increasing the current command value again from there.

At the time, in the maximum power control circuit 23, the voltage derivation of the output power is calculated and the current command value is increased in the case that the derivation is negative. The output power soon exceeds a maximum power point and starts to decrease. In the maximum power control circuit 23, the state is detected by the fact that the voltage derivation of the output power becomes zero or positive and the current command value is changed so as to start climbing again from the point where the prescribed voltage is added to the operating point voltage at the point of time.

IPC: H01S5/068
Filed: 1990-09-05
Abstract: PURPOSE:To make it possible to shorten control time of optical output by allowing a duty compensation circuit to make up for duty change in optical output waveform. CONSTITUTION:When a semiconductor laser 1 is actuated, its output state is monitored by a photodiode 4 where the output waveform of the photodiode 4 is adapted to enter a duty compensation circuit 6. Therefore, the compensation circuit 6 controls a pulse drive circuit 3 and drives a semiconductor laser 1 so that it may adjust the duty of optical output waveforms. During this operation, an automatic output power control circuit 5 (APC circuit) is subject to the output of the photodiode 4 and controls the pulse drive circuit 3 so as to make constant the optical output. This construction makes it possible to cut down control items by driving the semiconductor laser only by means of the pulse drive circuit and provide stabilized optical output constantly.
