Title: Method for growing compound semiconductor
Inventor: ITO TAKAO
IPC: H01L21/203
Filed: 1986-02-17
Abstract: PURPOSE:To readily grow a uniform thin single crystal film which has less structural defects by growing a compound semiconductor layer of specific thickness on a compound semiconductor crystal substrate. CONSTITUTION:The same compound semiconductor is grown at a temperature not higher than 450 deg.C by a vapor phase growing MOCVD method or an epitaxial MBE method 200Angstrom  or less thick on a compound semiconductor substrate as a buffer layer, and the same compound semiconductor epitaxially grown film is grown by the normal method on the buffer layer. Since the epitaxially grown film is laminated by an ordinary method on the buffer layer grown by the MBE method at 250 deg.C of substrate temperature and approx. 100Angstrom of film thickness, the adverse influence of substrate defects existing in semi-insulating LEC (Liquid Encapsulated Czochralski) GaAs semiconductor substrate can be reduced.

Title: Inverter circuit
Inventor: MATSUMOTO TOSHIYA
IPC: H02M7/537
Filed: 1993-02-22
Abstract: PURPOSE:To increase the capacity of an inverter while reducing its size and noise by connecting the primary winding of a stepup transformer to an oscillation transformer and the secondary winding to an piezoelectric transformer. CONSTITUTION:When a DC voltage is supplied to an inverter circuit, one switching element is turned on to excite an oscillation transformer T2 and to apply a voltage to a step-up transformer T1, thereby turning on the switching element quickly. When an oscillation transformer T saturates magnetically, the switching element is turned off and simultaneously with it an oscillation transformer T2 generates a reverse voltage to turn on the other switching element. In this way a series of operations is repeated, in which the two switching elements are turned on alternately to supply a voltage from the secondary winding of the step-up transformer T1 to the primary winding of a piezoelectric transformer T3 by connecting the self-oscillation of the oscillation transformer T2, thereby outputting a high voltage, increased by the specified step-up ratio, to the output terminal of the piezoelectric transformer T3.

IPC: H03K17/78
Filed: 1987-02-14
Abstract: PURPOSE:To constitute a latching relay by semiconductor components at one side by using two light emitting diodes and a gate turn-off SCR. CONSTITUTION:In giving an input signal between input terminals T2 and T3, a light emitting diode LD2 is lighted and a gate turn-off SCRGTO1 is turned on. After an input signal is once given to the GTO1, it keeps its output state. The capacitor C1 is connected between output terminals T4 and T5 through a switch circuit 2 and charged. In turning off the GTO1, an input signal is given between input terminals T1 and T3 and the light emitting diode LD1 is lighted to throw the switch circuit 2 to the position of a terminal (a) to connect the capacitor C1 between the gate and cathode of the GTO1. Thus, the GTO1 is turned off. The latching relay is constituted by semiconductors.
