Title: Method and device for epitaxially growing in liquid phase
Inventor: HASHIMOTO TAKAHIRO
IPC: C30B19/00
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To provide uniform temperature difference in a solution without using a cooling part. SOLUTION: A cylindrical quartz pipe 21 is provided in the vertical direction in such a manner that the upper side of the peripheral surface of the quartz pipe 21 is heated by a heater 22 provided at the high temperature side, having a prescribed length in the axial direction and the lower side of the peripheral surface of the quartz pipe 21 is heated by a heater 23 provided at the low temperature side, having a prescribed length in the axial direction. Thereby, two uniformly heated zones having a temperature difference Δt deg.C are formed at upper part and the lower part of the atmosphere in the quartz pipe 21.  A boat 24, on which a semiconductor substrate 35 and a solution 42 are mounted, rotates on its own axis and is revolved according to the rotation of a rotation box 25, thereby the solution 42 and the semiconductor substrate 35 are uniformly and continuously moved in the horizontal direction. Thus, the effect of the temperature distribution in the atmosphere on the solution 42 and the semiconductor substrate 35 is averaged. Accordingly, it is possible to impart uniform temperature difference in the up-and-down direction in the solution without necessitating the installation of a cooling part for absorbing heat at the lower part of the quartz pipe 21 and complexing the constitution of the growing furnace.

Abstract: PURPOSE:To obtain the interconnected transmission system of a pumped storage power station making a large remodeling unnecessary and solving the problem of stability by providing a self-excited converter instead of a separately excited converter and by controlling the output frequency of the self-excited converter. CONSTITUTION:At the time of starting an apparatus, a converter 5 is operated, a DC transmission line 4 is charged with electricity, and the DC side voltage of a self-excited converter 3 is set to a rated value. Then, the self-excited converter 3 is started at a low frequency and with a low voltage output. The synchronous generator of a pumped storage power station starts rotation by the output voltage. The frequency and output voltage of the self-excited generator 3 is gradually made higher so that the number of revolutions of the generator is raised, and pumping is started with suitable timing. Thereafter, a pump discharge rate of flow can be arbitrarily controlled according to the set value Pref of a conversion power. Thus, it is possible to eliminate large remodeling of a generator-motor and to operate a stable pumped-storage power station.
