IPC: C30B29/40
Filed: 1977-09-12
Abstract: PURPOSE: To manufacture a single crystal low in dislocation density and small in thermal strain at a high crystallizing rate and with good reproducibility, which is used as a compound semiconductor, by forcing heat to escape through a heat-dissipating hole of boat-size made on the top of an electric furnace so as to prevent supercooling.  
     CONSTITUTION: An electric furnace has on the top a boat-sized heat-dissipating hole 10, through which heat is forced to escape upward H so as to prevent supercooling. Thereby, supercooling is prevented by maintaining temp. gradient at 0W 1.0°/cm., pref. not greater than 0.5°/cm. and dislocation due to thermal strain is prevented from arising. By the heat-dissipating method described above, fresh crystal plate following the crystal growth forms on a free surface which does not contact with the boat 3 wall, and grows from the growing nucleus as a starting point in the direction of the boat 3 wall. The letter 9 in Figure shows an interface between crystals. As the result, adverse effect due to the boat 3 wall can nearly be neglected; once a nucleus of crystal having no dislocation is produced, it grows to the last end of the crystal without causing dislocation

Filed: 1988-05-07
Abstract: PURPOSE:To assure high resistance to dielectric breakdown by constructing a slide die provided movably back and forth with respect to a molding cavity such that the slide die has a function of fixing a support plate at a given position and a function of restricting a flow of sealing resin into a first region formed on the side of one principal surface of the support plate.

Accordingly, when the plunger lowers to a height where a second region 26b is substantially fully filled with the sealing resin 27, a first slide die 22 is lifted. Moreover, when the plunger lowers to a height where a first region 26a is filled to half or more thereof with the sealing resin 27, a second slide die 23 is lifted. Thus, time points when the first and second slide dies 22, 23 start to move can be determined with ease. Hereby, a satisfactory resin sealant can be formed below the support plate.

IPC: H02M3/335
Filed: 1981-07-16
Abstract: PURPOSE:To protect a load and a regulator, by keeping the stop of oscillation of a switching element against a failure of a self-oscillation type switching regulator. CONSTITUTION:A time ranging from a time t=0 of application of AC voltage to a time t1 when a thyristor 15 of a start circuit 14 turns on, is set larger than a time when a switching transistor (TR)1 surely starts the oscillation. When the TR1 completely turns on and the increase in the collector current stops, an electromotive force of an input wiring 201 is inverted, a reverse bias is applied to the TR1, the TR1 is turned on and the oscillating operation is repeated. Since the thyristor 15 is turned on with a voltage across a capacitor 17, the oscillation stop of the TR1 can be kept in case of a failure of load circuit connected to an output winding 203.
