Title: Method and device for isotropic pressure-molding
Inventor: URASAKI SOUKICHI
IPC: B22F3/04
Filed: 1984-02-15
Abstract: PURPOSE:To make the increasing and decreasing rate of the pressure in a high- pressure molding vessel freely controllable and maintaining easily the pressure in the vessel by suing a piston actuated by a screw shaft for pressurizing the pressure medium in the high-pressure molding vessel. CONSTITUTION:A metallic powder material to be molded is put into a suitable vessel 10 and is thereafter hermetically closed by a cap 20. The water in a tank 12 is supplied to the vessel 10 by the operation of a pump 11. The water fills the inside of the vessel 10 and fills the water chamber 19 of a pressurizing cylinder 1 through a pipeline 9. A selector valve 18 is closed upon stopping of the pump 11 and a worm 8 is driven to rotate a nut 5 via a worm wheel 7 thereby advancing a screw shaft 3 and a piston 2 and pressurizing the water in the water chamber 19. The pressure is transmitted through a conduit 9 to the vessel 10 so that the powder material to be molded in the vessel is subjected to isotropic pressure-molding by the water of the pressure medium thereby producing the molding having an intended shape. The pressure reduction in the vessel 10 is easily accomplished by a selector valve 16 to permit quick starting of the succeeding high-pressure molding operation.

Title: Method and apparatus for measuring fluid medium
Inventor: JIIKUFURIITO ROOMAN
IPC: B22D39/06
Filed: 1989-02-07
Abstract: PURPOSE: To measure a molten metal accurately by introducing a medium in a flow-out piece detected through a level detector into a vessel for a set time after a specific level is reached in order to attain a desired metric pressure of gaseous medium. CONSTITUTION: A flow-out piece 2 and a level detector 3 are arranged in a vessel 1 for molten metal and the detector 3 is connected with a controller 4. Pressure from a compressed air source is regulated to a desired level by a pressure regulator 7. Metric pressure is regulated by opening a solenoid valve 8 for a predetermined time after the liquid metal reached the outlet height A. Upon elapse of a metric time TD1 , an exhaust valve 13 is opened and the air is discharged from the vessel 1 through a throttle 14 and a smaller quantity of liquid metal is drained from the flow-out piece 2. When the flow-out rate is increased again after elapsing a metric time TD2 , a solenoid valve 10 is opened and the air is fed into the vessel 1 through a throttle 11. Consequently, another metric pressure level can be regulated and an accurate measurement can be achieved only through time control.

Abstract: PURPOSE:To relax the sharp end of an edge at a groove opening part, to prevent the film thickness of a dielectric layer from becoming locally thin, to make the film thickness nearly equal and to enhance the reliability of a groove- shaped capacity part by a method wherein the edge at the groove opening part of the groove-shaped capacity part is tapered. CONSTITUTION:A field oxide film 2, an n<+> layer 3, a silicon oxide film 4, a silicon nitride film 5 and an opening 6 are formed on a p-type silicon semiconductor substrate 1; after that, the substrate 1 at the part only of the opening 6 is again oxidized selectively by a thermal oxidation method; a silicon oxide film 7 is formed. At this time, the film 7 is eroded in the transverse direction between the film 5 and the layer 3; an oxide film (bird's beak) in this eroded part is controlled by the film thickness of the film 5 and the film 4. The film thickness of the film 5 and the film 4 is selected in such a way that an excessively large stress is not exerted on the substrate 1 at the growth of the bird's beak and that edges 9 of a groove 8 are tapered properly. Thereby, it is possible to prevent the film thickness of a dielectric layer 12 from becoming locally thin, to relax the concentration of an electric field and to form a groove-shaped capacity part whose reliability is high.

Abstract: PURPOSE:To easily and certainly curve even a long insertion part by providing the drive chamber filled with a magnetic fluid arranged in the insertion part of an endoscope, a magnetism generating means applying the magnetic fluid and a control apparatus for controlling the driving of the magnetism generating means. CONSTITUTION:When a curving operation dial 8 is rotated, the shaft of an encoder 35 is rotated, and the rotary direction and quantity of rotation thereof are sent to a control apparatus 36. Whereupon, the control apparatus 36 supplies a current to each coil 29 of a magnetic fluid actuator row 21 on one side by a current supply apparatus 34 and, therefore, a magnetic field is generated in the drive chamber 31 within each bellows part 26 provided to the peripheral part of the coil 29 and a magnetic fluid 32 flows in the bellows part 26 to increase the volume of said bellows part 26 so as to extend the same in the long axial direction thereof. At this time, a reservoir tank 27 is contracted because of elasticity. The surface of a curving part 5 on one side thereof is ready to extend by the force extending the bellows part 26 but, since the extension thereof is limited, the curving part 5 is curved in a desired direction. Therefore, even when an insertion part is long like an industrial endoscope, the curing part 5 can be curved easily and certainly.
