Title: Heat radiation control plane
Inventor: HATADA TOSHIO
IPC: B64G1/50
Filed: 1987-09-02
Abstract: PURPOSE: To achieve light weight and simple structure, and elaborate heat radiation control by using a thin piece-grouped blade comprising elements of tongue-like thin pieces each combining a thin sheet shape memory alloy and a bias spring as opening/closing mechanisms. CONSTITUTION: When heat generation quantity of an equipment installed on a lower part of a heat radiation board 3 is small, and as temperature of the heat radiation board 3 is low, then tongue-like thin piece are kept closed, so a heat radiation rate on the surface of the thin pieces 1 is small to restrain heat radiation quantity low. As the heat generation quantity of the equipment is increased to increase temperature of the board 3 to reach a transformation point of shape memory alloy pieces 2, deformation force of shape memory alloy gets over spring force, and the tongue-like thin pieces are deformed to open, so surfaces 3, 2 of a large heat radiation rate are exposed to increase heat radiation quantity.  By thus composing a heat radiation control surface of a group of the separately actuating small tongue-like thin pieces, elaborate temperature control can be performed, and a special actuatior is not required, thereby simple structure and light weight can be achieved.

Title: Operation of gas laser oscillator
Inventor: IDE TOSHIO
IPC: B23K26/064
Filed: 1988-09-02
Abstract: PURPOSE:To prevent a shift to an arc discharge and to maintain a stable glow discharge by a method wherein, when an operation at a prescribed laser output at a constant pressure of a laser gas is shifted to a high-output operation, a laser gas pressure is adjusted to a value which is higher than a prescribed pressure. CONSTITUTION:The inside of a wind tunnel 20 of an oscillator 10 is evacuated; a laser gas is filled to about 1/30 atmospheric pressure; a glow discharge is generated uniformly over the whole range of an electrode in an electric discharge part 12; an ordinary operation is started. Since a laser output and a laser gas pressure are in a proportional relationship within a certain range, the laser gas pressure is increased to 1/20 to 1/15 atmospheric pressure when a full-output operation is started. Thereby, even when a zero-output operation and a large-output operation are repeated, a stable gas discharge can be secured.
