Title: Method for preventing clouding of window in laser cvd device
Inventor: ONISHI HIROSHI
IPC: C23C16/48
Filed: 1987-03-18
Abstract: PURPOSE:To prevent the clouding of a window for introducing laser light and to efficiently utilize laser light by intermittently radiating high output laser light on the window during a CVD reaction to remove a deposit sticking to the window. CONSTITUTION:A reactive gas G2 is introduced into a reactor 1 from the inlet 5 and laser light 3 is introduced through the window 2 to photo-dissociate the reactive gas G2 in the reactive gas region 8 and to deposit a thin film on a substrate 7. At this time, the reactive gas G2 diffuses and reaches a region 10 near the window 2 and radicals produced by photo-dissociation with the laser light 3 begins to form a deposit on the window 2. Before the deposit grows to such a degree that the transmissivity of the window 2 is lowered, high output laser light 3A having >=about 10MW/cm<2> intensity is intermittently radiated on the window 2 to remove the deposit from the window 2 by sputtering. Thus, the effective intensity of the laser light 3 introduced into the reactor 1 is always kept constant and the laser light 3 is efficiently utilized.

Abstract: PURPOSE:To make a packing container biodegradable as a waste material after use by underground bacteria and solve environmental pollution problems, by kneading pulverized materials of plant fibrous bodies of bamboo, sugar cane, etc., together with a naturally decomposing binder and molding the kneaded mixture and drying and solidifying it to constitute the packing container. CONSTITUTION:Plant fibrous materials like bamboo as a raw material 1 are pulverized by a crusher 2 to make a pulverized material 3. And a water solution 4 of starch paste as a binder is mixed with the pulverized material 3 and kneaded together. The kneaded material 5 is molded by molding frames 6, 7 and then dryed and solidified to form a container 8. Bamboo and sugar cane grow quickly and the regeneration is fast and hence, it does not cause the destruction of nature. In sugar cane, it can be used for effective utility of the waste after having wrung juice out of the cane. Since starch paste for instance is used as a naturally decomposing binder, the waste material after use is naturally decomposed by bacteria in the ground.
