Title: Method of forming nitride compound semiconductor layer
Inventor: UDAGAWA TAKASHI
IPC: C30B25/14
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To promote the generation of a grown island, having a flat surface and grown of an In-containing nitride compound semiconductor having low reactivity and high decomposability by reducing the volumetric ratio of a gas of a large thermal conductivity to a gas of a small thermal conductivity with the lapse of time along with increase in the thickness of the nitride compound semiconductor layer. SOLUTION: In vapor growth of a nitride compound semiconductor layer, a gas creating a growth atmosphere is not a gas material but a gas-type used as a diluent gas of a carrier gas or a doping gas. In a growth atmosphere made by mixing a gas having a volume V0 and a gas having a smaller thermal conductivity and a volume V, the volumetric mixing ratio γ of both gases is calculated from V/V0 . In the case where a mixed gas of hydrogen having a relatively large thermal conductivity and argon having a relatively small thermal conductivity is used as a growth atmosphere, at the time of forming the nitride compound semiconductor layer, a numerical value given in accordance with an intended ultimate thickness is used as an initial value, and V/V0 is reduced with the lapse of time along with increase in the thickness.

Title: Power converter apparatus
Inventor: YAMATO IKUO
IPC: H02M7/48
Filed: 1988-09-28
Abstract: PURPOSE:To suppress a spike voltage and to reduce a circuit loss by absorbing through a capacitor the spike voltage generated at the time of commutation of a frequency converter circuit, and by connecting the capacitor with a proper transformer according to the polarity of a transformer output to regenerate the charge of the capacitor on the transformer side. CONSTITUTION:Just before the secondary voltage e2 of a transformer 3 attains zero, a transistor Tr 43 is turned ON and a capacitor C709 is charged with a voltage twice as much as the peak value of a voltage e2 via the Tr 43 and diodes D705, 708. When commutation occurs from Trs 41, 43, the stored energy of a circuit inductance such as the leakage inductance of a transformer 3 is absorbed by C709. Thus, a spike voltage generated in a circuit can be suppressed. Also, when TRrs 701, 704 are turned ON according as a voltage e2 attains a peak value, a discharge route for C709 is formed and the absorbed energy is released to a load.
