Title: Self-oscillation type high voltage power source
Inventor: MAEBA YUKIO
IPC: H02M7/537
Filed: 1982-04-13
Abstract: PURPOSE:To prevent an oscillation transistor from thermally breaking down by detecting and protecting the voltage of a recovery condenser. CONSTITUTION:When an oscillator is in a normal oscillating state, a protecting transistor 11 is maintained OFF. When a high voltage output is shortcircuited, an oscillation is attenuated, the voltage of a recovery capacitor 5 is raised, and the voltage at the connecting point of the resistors 8, 9 is raised. Accordingly, the transistor 11 is turned ON, and the output voltage of the control circuit 10 is reduced. The oscillation of the transistor 3 becomes extremely weak state, thereby protecting the power source against the shortcircuit of high voltage.

Title: Composite body of aluminum casting
Inventor: TAWARA HIROMITSU
IPC: B22D19/02
Filed: 1981-04-28
Abstract: PURPOSE:To obtain a composite body of high strength and toughness wherein an expanded Al alloy material and an Al alloy casting are metallically bound in casting the former into the latter by melting contact parts of both partially. CONSTITUTION:This composite body is constituted of an expanded Al alloy material 5, an Al alloy casting 6 casting said material therein and a fused layer 7 of both. To melt the material 5 to a desired extent in producing such composite material, it is preferable to set the volume thereof at about 1/5 with respect to the entire part of the composite material and to preheat metallic molds to about 300-500 deg.C in the stage of casting. Under conditions other than these, metallical binding is likely to be insufficnent. Depending upon the kinds of the constituting forms of the composite body, it is necessary to interpose a heat insulating material, for example, ceramic fibers, between the expanded material and the metallic molds to insulate the expanded material and molten metal against heat.
