Title: Correcting method for section of measuring receptacle
Inventor: TAKAMURA AKIO
IPC: G01F23/00
Filed: 1980-05-01
Abstract: PURPOSE:To obtain a correcting method for a section of an uniform measuring receptacle, by a method wherein a minute increase or decrease amount in liquid in a receptacle is divided by an increase or decrease in pressure of a liquid column, and a correction body is cut or added according to the dividing results. CONSTITUTION:Water flow paths 3 and 2 and a pressure measuring path 5, in which a differential pressure converter 6 is situated in the middle of the path 5, are installed in a receptacle 1, and a correction body 4 having an uniform section is located in the receptacle 1. After the receptacle 1 is filled with fluid through an inlet path 2, the inlet path 2 is closed. An inlet path 3 is then opened, and an approximately constant amount of liquid is flowed out intermittently. With this a decreasing height of a liquid column, which is due to a decrease amount in output of the differential pressure converter, is measured. After liquid in the receptacle 1 flows out, an intermittent flow amount is divided by the decreasing height of the liquid column, and the spherical surface of the correction body 4 is modified by cutting and adding according to the division results to change the section. This causes the uniformalization of the section of the receptacle 1 when the correction body 4 is set into a condition to be placed in the receptacle 1.

Abstract: PROBLEM TO BE SOLVED: To provide an excellent thin film semiconductor device stably in a low temperature process by depositing an amorphous semiconductor film using silane of high order as one of material gases by a chemical vapor deposition method and then crystallizing the amorphous semiconductor film in the solid phase. SOLUTION: A semiconductor film, chief of which is silicon, as represented by an amorphous silicon film is deposited using silane of high order (SinH2n+2: (n) is an integer of 2 or above) as one of material gases. Considering the price and the safety, disilane (Si2H6) is most appropriate as silane of high order, For a high-purity and high-quality semiconductor film, the rate (R=QL/QSin) of the leakage flow (QL) from outside the system to the flow (QSin) of silane of high order should be about 10 ppm or above (R<=10-5) in a low pressure chemical vapor deposition system. Accordingly, a high vacuum low pressure chemical vapor deposition system is used and a semiconductor film is started to be deposited after the degassing flow from a substrate becomes about the leakage flow (QL) from outside the system or below.

Filed: 1978-05-18
Abstract: PURPOSE:To prevent the bubbles produced in an ink tank from entering the inside of an ink jet heat by providing a branch pipe to part of an ink feed pipe and providing a filter immediately after the branch pipe. CONSTITUTION:When a bubble occurs in an ink tank 6 and this bubble is moved toward a head 5 by the flow of the ink by passing through an ink tank feed pipe 7, the large bubble moves upward directly toward a branch pipe 8 and escapes to the atmosphere through the outlet of the branch pipe. A small bubble stays in front of the filter 8 and finally escapes to the atmosphere through the branch pipe 8. Hence, transmission of the bubbles to the areas behind the filter part 9 of the ink feed pipe 7 does not occur.

Abstract: PURPOSE:To restrain a base area from being expanded and to make a mask alignment margin unnecessary by forming, in a self-alignment manner, the whole base region including an inert base inside an isolation region to be formed by photoetching. CONSTITUTION:While a vertical wall of an isolation oxide film 3 in a groove 14 formed by making an etched face in an active region of a transistor as a bottom face is utilized, three regions of an inert base 11, an active base 11a and an emitter 13 are shaped in a self-alignment manner; accordingly, said three regions are formed at the narrow active region which has been prescribed by a photoetching operation used to form an isolation region. That is to say, expansion of a base region by diffusion in the transverse direction of the inert base region 11 is suppressed by the existence of the isolation oxide film 3 in this constitution. In addition, since said three regions are all formed in a self- alignment manner, it is not required to consider a mask alignment margin from the viewpoint of a manufacturing method.
