Title: Method and device for casting aluminum
Inventor: DEMUKAI NOBORU
IPC: B22D23/00
Filed: 1991-03-22
Abstract: PURPOSE:To secure sufficient molten metal running and to cast a thin product in high accuracy by covering a cover on a mold, charging aluminum alloy into an opening part in a core, heating and melting, evacuating air in closed space formed between the cover and the core and casting. CONSTITUTION:The mold 1 is formed by assembling the core 12 having permeability and providing the opening part 13 to a master mold 11 having heat resistance and non-permeability. The cover 2 is covered on this mold so as to close part communicated with the out part only at the opening part in the core, and by using the heat resistant seal, gap between the cover and the core is sealed. The aluminum metal is charged into the opening part in the core and heated from outside of the mold and melted and also, the air in the closed space 5 formed between the cover and the core is evacuated and the casting is executed. By this method, the thin product is manufactured at high accuracy, and also as the material for runner is scarcely necessary, yield of the casting is improved.

Title: Power supply circuit for load, power supply circuit for driving load and ac load driving method
Inventor: IKEDA TAKAAKI
IPC: H02M7/537
Filed: 1990-03-09
Abstract: PURPOSE:To eliminate energy loss and to enhance power efficiency by connecting one end of a load circuit comprising a series LCR circuit to the coupled output terminal of an inverter comprising a pair of positive and negative switches whereas connecting the other end of the load circuit to the neutral potential or ground terminal of a DC input power supply. CONSTITUTION:In a load circuit, a resistor or a load 4 having diode characteristics, a bipolar capacitor C, and an inductor L constitute a part of series coupled component. One end of the load circuit is connected with the coupled output terminal 7 of an inverter oppressing a pair of positive and negative switches Tr1, Tr2. The other end of the load circuit is connected, for example with the intermediate potential terminal of the positive and negative DC input power supply +E, -E of an inverter or the ground terminal 8. Power efficiency can be enhanced by recovering excessive load current due to the current, which is not converted into light or heat but simply passes through the load 4, by means of a reverse current flow. Furthermore, loss can be eliminated by shifting the phase between the load voltage and the load current thereby suppressing the rising of the load current.

Abstract: PURPOSE:To enhance rust resistance of a surface treated steel sheet by simple after treatment which has been electrolytically treated by chromic acid by galatinizing a chromium hydrated oxide layer in the uppermost layer of the steel sheet and thereafter immersing this gelatinized layer in an aq. soln. which contains any one of Ca, Mg, Ba and Sr ions and has the prescribed temp. and pH or electrolyzing it. CONSTITUTION:A steel sheet is electrolytically treated by chromic acid to produce a sollike chromium hydrated oxide layer on the surface thereof. This layer is washed with water, dried and gelatinized. Successively this gelatinized layer is immersed in an aq. soln. which contains any one of Ca, Mg, Ba and Sr ions at 3-100ppm and has 7-10pH at 60-100 deg.C in a short time or electrolyzed.
