Abstract: PURPOSE:To permit production of a sintered body having excellent cold plastic workability by loading a high-silicon Al alloy powder contg. silicon at a specific ratio into a container provided with an Al alloy plate just before an extrusion die and sintering and extruding the powder under compression. CONSTITUTION:After the Al or Al alloy plate 3 is set at a prescribed thickness into the extrusion container 2 in which the die 1 is set, the high SiAl alloy powder 4 contg. 13-30wt.% Si is loaded therein independently or after an additive is added and mixed to and with said powder. A ram 5 is thereafter lowered to pressurize the powder. The extrusion pressure is then increased and the initial pressure is loaded to the powder 4 as the powder 4 is compressed. The powder is simultaneously sintered when the pressure is balanced and while such pressure is maintained for certain time. The plate 3 and the powder 4 are immediately extruded upon completion of the sintering. The plate 3 is formed to the thickness at which the plate withstands the compressive force before the completion of the above-mentioned sintering and to the thickness enough for cladding approximately the entire extruded length of the powder 4 to a sleeve-shape. The sintered body bonded integrally with the sleeve shaped clad extruded layer 7 of the Al or Al alloy on the core part 8 is thereby obtd.

Abstract: PURPOSE:To attach and detach a window and an output mirror in a short time and easily by a method wherein a gate is arranged between the window or the output mirror and a laser oscillator and a bypass valve and an air discharge valve are installed in a space between the window and the gate. CONSTITUTION:A gate 1 is installed between a laser beam extraction window 2 and an oscillator body 3; a bypass valve 8 and an air discharge valve 9 are installed in a space S between the window 2 and the gate 1. This gate 1 can be manipulated from the outside so that it can be shifted in a light path to pass a laser beam and outside the light path; the bypass valve 8 is connected in such a way that the oscillator body 3 is interconnected with the space S. When the window 2 is to be detached, the gate 1 is first shifted in the light path and the air discharge valve 9 is then opened; then, the space S is under atmospheric pressure; due to a pressure difference between the space and the inside of the oscillator body 3, the gate 1 is pressed toward the oscillator body 3 and crushes an O-ring 6; as a result, airtightness of the oscillator is kept. By this setup, a mount 5 for window use can be detached easily; the window 2 can be exchanged.
