Title: Light-supported mocvd method and semiconductor array laser
Inventor: JIYON II ETSUPURAA
IPC: C23C16/52
Filed: 1989-03-27
Abstract: PURPOSE: To form a semiconductor element with a region having a different band gap and a different refractive index in a semiconductor layer by giving chemical stoichiometric change and growth speed change to a compound semiconductor when using the laser support organic metal chemical vapor growth method. CONSTITUTION: The geometrical dimension characteristics and the field chemical stoichiometric characteristics of a thin film are generated by a scanning irradiation source 27 that is directed toward a spot being scanned across a growth surface in a chemical vapor growth reaction room 10. When the intensity of a Gaussian distribution spot, namely the optical intensity of an irradiation source spot at a selected region of the growth surface is changed, a deposition growth rate and the field chemical stoichiometric content of a thin film 34 being deposited increase.  Then, the change in the thickness of the thin film and that in chemical stoichiometric content can be selectively intensified or weakened when scanning the spot, thus creating, in a semiconductor element, a burial refractive index light waveguide region or a multiplex emitter for discharging at a different wavelength that is useful in a printer or light communication.

Title: Controller of power converter
Inventor: SHIBATA MITSUHIRO
IPC: G05F1/10
Filed: 1984-04-17
Abstract: PURPOSE:To control to reduce the decrease or the increase of a voltage at a load abrupt variation time by outputting a correction signal due to a deviation between a load feedback signal and a reference signal, and varying a gain in response to the correction signal. CONSTITUTION:When an abrupt variation in a load occurs, a DC voltage is varied from a target value. This variation becomes a voltage feedback signal VFBK, is compared with a voltage reference signal VREF, and when the deviation exceeds the prescribed value, a correction signal 6a in response to the exceeded amount is output from a correction signal function generator 5. The gain of a voltage control operational amplifier VC is corrected in response to the signal 6a. Thus, the decrease or the increase in the voltage at the load abrupt variation time can be controlled to extremely small.
