IPC: F04C25/02
Filed: 1985-11-13
Abstract: PURPOSE:To reduce starting torque by providing a check valve at the exhaust side of a screw vacuum pump and a closing valve at the intake side, while an air pump communicates to a flow path between both valves. CONSTITUTION:A screw vacuum pump 1 is provided on the exhaust side with a closing valve 5 for closing the intake side flow path, while on the exhaust side with a check valve 10 for preventing the counter flow of exhaust gas.

Title: Manufacture of silicon radiation-detecting element
Inventor: SUZUKI TOSHIO
IPC: H01L31/09
Filed: 1988-10-07
Abstract: PURPOSE:To obtain a silicon substrate with an uniform surface by using an etching solution with rate-determined reaction velocity, for the etching after the working of a silicon substrate as a material. CONSTITUTION:An etching solution 2 with rate-determined reaction velocity is used for the etching after the working of a silicon substrate 4 as a material. That is, when the etching solution 2 with rate-determined reaction velocity is used, etching is rate-determined at a velocity at which it makes a product reacting with the surface of the silicon substrate 4, so that the etching rate is constant and indifferent to the agitation state of the solution or the moving state of the substrate. Accordingly, the etching controllability becomes excellent and besides the uniformity of the reaction velocity inside the substrate surface is high. And, this makes it difficult for the characteristics of the element to be bed caused by the unevenness of the surface condition.

Title: Optical confluence circuit
Inventor: HIMENO AKIRA
IPC: H04B10/00
Filed: 1984-12-03
Abstract: PURPOSE:To shorten a circuit length and to permit a large-scale integration by providing plural optical guides for input on a base plate, providing an optical waveguide for output to intersect therewith and providing reflection faces on the intersected parts thereof. CONSTITUTION:The plural optical waveguides 3-1-3-n for input and one optical waveguide 4 for output intersecting therewith are provided on a base plate G. The reflection faces 6-1-6-n which incline at the same angle phi with both of the waveguides 3-1-3, 4 in both directions of the plate G are provided to the side faces in the intersected parts 5 of the waveguides 3-1-3, 4 for the input and output. The light of the reflection mode theta of which the angle with the side faces of the waveguides 3-1-3-n is below the critical angle propagates in the waveguides 3-1-3-n from the total reflecting conditions of the light. The light of the mode theta is made incident at the prescribed angle on the reflection face 6-k and the light inputted to the optical waveguide 3-k for output is outputted to an output port 7. The reflection mode theta is not affected by the reflection faces 6-k+1-6-n and therefore said light propagates in the waveguide 4 without radiation loss. The greater part of the light power is thus outputted to the port 7 and the optical confluence is made possible.
