Title: Vapor phase epitaxial growth apparatus
Inventor: KOBAYASHI NAOKI
IPC: H01L21/205
Filed: 1984-03-02
Abstract: PURPOSE:To improve controllability of the growth rate, by providing with means which allot metal organic gas to a reactive system and an exhausting system at a give flow-rate ratio, at the exit of the metal organic gas. CONSTITUTION:Changeable flow-rate distributing means 6 which allot metal organic compound gas to a reactive tube 4 and an exhausting system 10 at a given flow-rate ratio, are provided at the exit of the metal organic compound gas. For example, in a case where the growth is executed at a bubbling flow- rate of 10cc/min. of the bomb 5, the same GaAs growth rate as that in the case of a bubbling flow-rate of 2cc/min. of the bomb 5 is achieved, if openings of the valves 51, 52 are controlled so that the changeable flow-rate distributing means 6 can allot the gas to the reactive system and the exhausting system at a flow-rate ratio of 1:4. The larger the flow-rate ratio becomes, the more the growth rate can be reduced. In this case, since the bubbling flow-rate is 10cc/ min., unstable bubbling or bad controllability which may arise at a bubbling flow rate below 2cc/min. can be avoided.

Abstract: PURPOSE:To facilitate the center alignment between a brush bed and a pad made of materials which can easily bifolded, so as to prevent the manipulatability from lowering due to an eccentricity, by forming radial grooves in the bottom surface of the brush bed while attaching face fasteners thereon, excepting the grooves so as to attach the pad removably to the bottom surface. CONSTITUTION:A cruciform space 13 is formed on the lower surface of a brush bed 12, and face fasteners 14 are bonded to the bottom surfaces, excepting the space 13. Radial grooves may be formed in stead of the cruciform space, with the same effect. When a pad as an attachment is replaced with another for the purpose of dry-cloth wiping, wet-cloth wiping or waxing, the pad 15 is bifolded and aligned with one part of the cruciform space 13, and then the pad 15 is unfolded after confirming that the lengths of the pad projecting from the brush bed are equal to each other, thereby the pad 15 is attached to the brush bed 12. With this arrangement, it is possible to facilitate the center alignment between the brush bed 12 and the pad 15 while preventing the manipulatability from lowering due to an eccentricity, thereby it is possible to restrain the consumption power from increasing.

Abstract: PURPOSE:To prevent a reduction of amplifier output power of a main amplifier by detecting a signal applied to a coupler secondary side terminator of a distortion eliminating loop, and detecting a distortion extracting or distortion eliminating loop by a variation of an ascent and a descent of its output level. CONSTITUTION:The amplifier is provided with a detector 1 for detecting a signal applied to a terminator R4 of a secondary side of a coupler 14 of a distortion eliminating loop. When a vector regulator 21 of the distortion extracting loop or a vector regulator 22 of the distortion eliminating loop causes a malfunction, the detector 1 provided in the terminator R4 of the coupler 14 detects a variation of a detecting output level caused by its residual signal. In such a way, it is known that the distortion extracting loop or the distortion eliminating loop causes the malfunction. Its detector 1 is provided in the part of the terminator R4 of the secondary side of the coupler having no direct relation to output power of the amplifier, therefore, it is unnecessary to reduce output power amplified by a main amplifier 10.

Abstract: PURPOSE:To always obtain the maximum output power regardless of the change of the irradiated light quantity or the temperature change of elements, by using a generator for voltage command correction value that delivers the correction value based on the output voltage and the output current of a solar battery. CONSTITUTION:Both the DC current and voltage detectors 18 and 20 detect the output current Id and the output voltage Vd of a solar battery 10 respectively. Then a generator 22 for voltage command correction value samples periodically both current Id and voltage Vd obtained by detectors 18 and 20 respectively for calculation of the output power (Pd=IdXVd). The changing directions of the output power Pd and voltage Vd are judged for output of the voltage command correction value DELTAV. Then this value DELTAV and the voltage Vd are supplied to a voltage controller 24 and a converter 12 is controlled by the output of the controller 24. Thus it is possible to obtain the maximum output power at all times regardless of the change of the irradiated light quantity or the temperature change of elements.
