Title: Monitoring device for thickness of film
Inventor: HAYAKAWA TOSHIROU
IPC: G01B11/06
Filed: 1979-09-13
Abstract: PURPOSE: To provide a device capable of monitoring the thickness of the formed film by a method wherein one end face of an optical fiber is located at the same level as a substrate for the film formation in a thin-film forming device, and the change in the reflection factor is detected through the use of the light from the other end face of the optical fiber.  
     CONSTITUTION: A source of vapor 2 and the substrate 3 are placed in the bell jar 1 of a vacuum evaporator, and the optical fiber 4 is inserted into the bell jar 1. The light from a light source 7 is introduced into the optical fiber 4 through a coupling lens 5, the reflected light from the one end face of the optical fiber 4 located at the same level as the substrate 3 is directed into a detector 8 by a half-mirror 6, and the output of the detector 8 is monitored. In this case, when a substance of a refractive index n 1  is deposited on a substance of a refractive index n 0 , the reflection factor of the light as viewed from the side of the substance of the refractive index n 0  changes periodically with the thickness of the film. Accordingly, the thickness of the film can be monitored by monitoring the output of the detector 8.

IPC: F23D3/14
Filed: 1978-09-25
Abstract: PURPOSE: To prevent the accumulation of soot at each part within the combustion chamber while restricting the generation of yellow flame and soot caused by the primary combustion by obtaining a mixture of fuel gas and air at the best ratio by regulating the aperture of the flame piloting baffles.  
     CONSTITUTION: Combustion chamber 9 and 10 are divided into the primary combustion chamber 9 and the secondary chamber 10 respectively by the narrows 12. Primary air is fed to the primary combustion chamber thru the primary air feed part 3, while the secondary air is fed to the secondary combustion chamber thru the secondary air feed part 4. Flame piloting baffles 13 are established at a position close to a part 3a of the primary air feed part, and the air blown out of the air feed port 3a hits against the baffles 13 where its blow direction is deviated. At this time, a part of the primary air is used for preliminary mixing while its remainder is used for the primary combustion. Combustion gas being carburetted is fed to the secondary combustion chamber from the porous body 1 and there a complete combustion is performed. As for the aperture A between the flame piloting baffles, less than 80% of the most wide size of the combustion chamber is considered to be the optimum.

Title: Arithmetic unit
Inventor: YAMADA KATSUHIKO
IPC: G06F7/506
Filed: 1990-05-08
Abstract: PURPOSE:To increase the processing speed of an arithmetic unit by giving the control information of different kinds to each arithmetic cell and actuating these cells in parallel with each other to plural bit fields stored in a single word length. CONSTITUTION:A cell control information storage means 2 stores the different m-bit control information (m X n) which control (n) pieces of arithmetic cells 1. Each cell 1 consists of a carry selection part 3 and an arithmetic part 4. The part 3 receives an m-bit control signal selects one of the carry output and logic 0 or 1 of a slave arithmetic cell 1 as a carry input. Thus a connection range of bit fields can be changed according to a fact whether the carry output of the slave arithmetic cell 1 should be selected or not. In such a way, the cell 1 can perform different actions for each bit when different kinds of control information are given to the cell 1. As a result, plural bit fields can be processed in parallel with each other and the processing speed of an arithmetic unit is increased.
