Filed: 1987-07-20
Abstract: PURPOSE:To retain a fine connection hole and to improve production yield and reliability, by opening the connection hole in an insulation layer formed on a first conductive layer and forming a metallic column on the first conductive layer inside the connection hole and forming a second conductive layer connected with the metallic column and next by tapering sidewalls of the connection hole. CONSTITUTION:An SiO2 layer 12 is formed on an Si substrate (a first conductive layer) 11, and a contact hole 13 is opened. Next, tungsten 14 is made to selectively grow as a metallic column. Sidewalls of the contact hole 13 are tapered 13 with starting points where the side walls contact with an upper plane of the tungsten. Namely, selective sputter etching by oxygen ions is used to form tapered parts 16 on the side. walls of the contact hole 13. Since the tungsten 14 is not etched accordingly, the positions of the points 15 are not varied. Therefore accompanied by slight decrease in film thickness of the SiO2 layer 12 on a flat plane, an angle theta of the tapered part 16 is only changed from 90 deg. into 0 deg.. The angle theta of the tapered part 16 is thus determined. After the sticking of a metallic layer, a wiring layer 17 is formed as a second conductive layer by lithography and etching.

IPC: G01M9/02
Filed: 1985-08-14
Abstract: PURPOSE:To hold the Reynolds number of a measuring part to a set value even if the total temp. of the measuring part changes during an airing time, by calculating the total pressure value of the measuring part on the basis of the total temp. or stationary temp. of a gathering tunnel and regulating a pressure regulating valve to hold said value.

Title: Signal output circuit
Inventor: SUGIURA KENRO
IPC: H03K5/12
Filed: 1984-08-27
Abstract: PURPOSE:To reduce a delay of sigal transmission and to prevent te generation of head with an internal element of a drive circuit, by supplying the output of a 1-shot circuit to the control terminal of a switching element and putting the switching element under a conduction state while signals are delivered from the 1-shot circuit. CONSTITUTION:When a signal Sa to be trasmitted is changed to a low level from a high level, the pulse of the fixed time width (t) is delivered from a 1-shot circuit 12. Then a transistor TR1 is set ON for an extremely short time. Thus a large current is supplied to a trasmisson line L for a short time via a resistance R3 and the TR1. Then, the electrostatic capacity of the line L and a capacitor C1 are charged in a short time. As a result, the potential Vb of the input terminal of a buffer 11 is set at a high level with an extremely short time delay from the fall of the signal Sa. This can reduce greatly the transmission delay of signals and then decrease the power consumption of both the R3 and the TR1.

Abstract: PURPOSE:To obtain the titled coke having excellent moldability and improved with respect to puffing characteristics, by calcining raw coke produced by the delayed coking method using a heavy oil derived from coal tar as a raw material by as particular method. CONSTITUTION:A heavy oil derived from coal tar is used as a raw material. A quinoline-insoluble matter is removed from the heavy oil, followed by production of raw coke by the delayed coking method. The raw coke is calcined at 1,050-1,450 deg.C for 10min or longer. The calcined coke is sieved into an undersize powder component having an average particle diameter of 5mm or less and an oversize granule component. The oversize granule component is further calcined at 1,500-1,800 deg.C for 10min or longer. The oversize granule component is mixed with the undersize powder component in such an amt. as will provide an oversized granule component/undersize powder component ratio of 20-80 pts.wt./80-20pts.wt. Thus, there is obtained coke suitable for use as a filler of a coal tar electrode for electrolytic steel making.

Title: Enclosed rotary compressor
Inventor: MITSUI KIMIYOSHI
IPC: F04C29/06
Filed: 1982-10-13
Abstract: PURPOSE:To improve the operational efficiency extending the life of the titled compressor by a method wherein an anti-vibration ring adheres to the periphery of a sealed container to prevent the resonance property at specified frequency from being displayed in the closed container resticting the vibration and noise sounding as well as dissipating the heat generated in case of operating a compressor. CONSTITUTION:An anti-vibration ring 4 is fixed to the periphery of a closed container 3 by pressed shrinkage fit so that the size of a seat 4a may be sufficient to encircle the entire or at least a part of cylinder block 6. Through these procedures, when external force F is exerted, a cmpression and a tension interfere with each other at the interface between the closed container 3 and the anti-vibration ring 4 finally to eliminate a neutral surface of definite force on the section of the closed container 3. Resultantly no resonance property at specified frequency may be displayed, diminishing the vibration of the closed containner 3, reducing the vibration and noise in a compressor as well as conducting the heat generated by the compressor to the anti-vibration ring 4 through the closed container 3 to dissipate the heat into the atmosphere.

Title: Slide tray driving mechanism in electronic equipment
Inventor: ODA SHIZUO
IPC: G11B17/056
Filed: 1990-07-09
Abstract: PURPOSE:To miniaturize equipment to its width direction by forming a rack gear at one side of a shaft, and simultaneously, installing a driving motor and a driving gear to be meshed with a rack gear and to be rotated by the driving motor at the innermost part of a slide tray. CONSTITUTION:When the driving motor 8 is operated, and the driving gear 7a is rotated on the rack gear 6 of the shaft 3, since the shaft 3 is fixed to a case 1, the slide tray 9 provided with a gear 7e is moved. Accordingly, the tray 9 is moved forward and backward by the forward or the reverse rotation of the motor 8. At that time, since a driving part such as the motor 8 and the gear 7e, etc., is installed at the innermost part of the tray 9, a space for the driving part need not be formed at the outer side part of the tray 9. Thus, the equipment can be miniaturized to its width direction.

Title: Measuring apparatus for liquid concentration
Inventor: YAMAMOTO MASAAKI
IPC: G01N35/08
Filed: 1982-10-15
Abstract: PURPOSE:To measure a quantity of a particular component in a sample solution by an apparatus wherein a column filled with solid matter is used in a flow injection mechanism instead of addition of a reagent solution to measure a dissolved amount of the solid component contained in the effluent. CONSTITUTION:A sample is first sent out of a liquid tank, etc. by means of a feeding tube 1 and feeding pump 2, and then divided at a branching point 3 into two streams one of which passes through a feeding tube 4 and a reference cell 5a of a colorimeter in a detecting section, and the other of which passes through a feeding tube 6, four- way selector 7, feeding tube 8 and a four-way selector 9 and is then discharged after passing a sample cell 5b. When the selectors 7, 9 are switched simultaneously, the sample now flows into the cell 5b through the tube 6, selector 7, column 7 and the selector 9. By keeping such a state for a certain time, a cleaning solution initially filled in the column 12 is discharged and then the sample dissolves a certain quantity of the solid in the column which is determined by a flow rate, while coming into a stationary state. It thus becomes possible to obtain concentration of a particular component in the sample based on the dissolved amount of the solid, by measuring the difference in absorbance between the cells 5a and 5b with a not shown colorimetric mechanism.
