Title: Vapor growth apparatus for semiconductor thin film
Inventor: SHIMOBAYASHI TAKASHI
IPC: H01L21/365
Filed: 1986-03-24
Abstract: PURPOSE:To make it possible to control the steep interface of a semiconductor thin film, by providing a double structure for connecting a raw material switching gas and a reacting tube, forming an inner tube with a porous material, flowing raw material gas through the inner tube, and flowing hydrogen or rare gas through a space between an outer tube and the inner tube. CONSTITUTION:Raw material gas 2, which is supplied through a raw material gas switching valve 1, is supplied to a reacting tube 5 through a tube system comprising an outer tube 3 and an inner porous tube 4. Hydrogen gas or rare gas 6 is introduced in a space between the outer tube 3 and the inner porous tube 4. By flowing the hydrogen or rare gas in the space between the outer tube and the inner tube, pressure in the tube is increased. Since the inner tube has the porous property, the hydrogen or rare gas, which flows between the outer tube and the inner tube, blows through the pores in the inner tube. Thus phenomena such as sucking and stagnation can be improved to a large extent. Therefore, the formation of a steep interface becomes easy, and super lattices and the like can be manufactured simply by vapor growth.

Title: Single-blade impeller pump
Inventor: KOBAYASHI FUMIO
IPC: F04D29/24
Filed: 1981-04-30
Abstract: PURPOSE:To make pumpability favorable in such a way that the blade end is smoothly continued to a conic hub, and contrived not to allow solid matter to clog into a gap between the outer periphery of the blade and the pump casing. CONSTITUTION:When an impeller is turned, a solid matter is flowed in the direction of arrow 14 at the part of the blade end 5. Though the tip of a conic hub 8 is shown in the figure, it does not exist actually due to the thickness of the blade 2, and as the blade end 5 is smoothly continued to the conic hub 8, the solid matter comes into spaces between the blade 2 and the conic hub 8, and also the pump casing 4 with hindrance. Thus, also the liquid containing the solid matter, etc. is sent between the outer periphery of the blade 2 and the pump casing 4 without clogging the gap. In consequence, pumpability is made favorable.
