Title: Steam valve opening/closing device
Inventor: KOBAYASHI MASARU
IPC: F01D17/10
Filed: 1992-02-19
Abstract: PURPOSE:To securely cut pressure oil to a disk damp valve by disposing at least three emergency oil trip solenoid valves in an emergency oil control system for cutting the pressure oil to be supplied to the disk damp valve in order to close a valve body, and supplying the pressure oil to at least two of the solenoid valves. CONSTITUTION:A steam valve A comprises an emergency oil control system B having a first, a second, a third emergency oil trip solenoid valve 20, 21, 22; and a control oil system C. For example, in the case where the second emergency oil trip solenoid valve 21 fails accidentally, the first and third emergency oil trip solenoid valves 20, 22 are not excited with application of a closing command to the steam valve A so that emergency oil delivered to a port a0 is discharged as a drain through ports b0, a2, b2. Accordingly, the emergency oil can be surely discharged even if the second emergency oil trip solenoid valve 21 is inoperative and a drain through ports c0, d0, a1 cannot be securely discharged. Consequently, the emergency oil to a disk damp valve 9 is cut so as to securely close the steam valve A.

Title: Liquid sprayer
Inventor: NOZAWA TAKAMITSU
IPC: F04B9/14
Filed: 1979-03-19
Abstract: PURPOSE: To effect exact and efficient operation from the beginning of operation by forming fine slit between the lower skirt and the first cylinder side wall and by installing annular concave groove having vertical rib.  
     CONSTITUTION: When sliding pipe member 30 is pushed down, the upper skirt section 41 falls passing a through-hole 28. By further pushing down to reach the lower limit, the lower skirt section 42 enters annular concave groove 26. At this time, because of rib 27, a part of the lower skirt leaves a space so that sealing function is lost. As a result, the first piston 31 loses water tightness against the cylinder side wall. This results in connection of cylinder and container through the gap between the skirt 42 and concave groove 26, gap between the internal cylinder 34 outer face and cylinder wall surface, and through hole 29. Thus, when the sliding pipe member 30 is pushed to the lower limit, residual pressure is exhausted into the container and performs priming.

Title: Ashing device formed by using dielectric barrier discharge lamp

IPC: H01J65/00
Filed: 1993-01-29
Abstract: PURPOSE:To ash a large area photoresist uniformly at high speed, and also downsize a device by using dielectric barrier discharge lamps as an ultraviolet ray radiating source. CONSTITUTION:In dielectric barrier discharge lamps 4a-4e, xenon gas is used as generating gas, and ultraviolet rays are emitted. Thereby, a part of treating fluid oxygen 1 ejected from a supply port 2 is converted into ozone by the ultraviolet rays in preliminary space 6 in an ashing duct 3. Mixed gas of the ozone and the oxygen is blown upon a photoresist. An active oxygen atom generated by decomposition of an oxygen molecule in treating space 7 acts directly on the photoresist before the ozone is generated. Thereby, the photoresist changed in quality after an ion is implanted can be removed at high speed, and the active oxygen atom by decomposition of the ozone generated in the preliminary space 6 acts also on the photoresist, so that the photoresist can be ashed and removed at high speed.

Title: Meander control device of rolling mill
Inventor: NAKAJIMA MASAAKI
IPC: B21B37/00
Filed: 1985-02-22
Abstract: PURPOSE:To set optimally a control gain and to control a meander with good accuracy by correcting the controlled valuable with the speed of rolled stock in the meander control device by the rolling load difference in the operation side and driving side. CONSTITUTION:A control loop gain is increased due to the meander of a plate becoming larger as the rolling speed is faster so much. Now in order to set always the maximum control gain alphal, it is necessary to make the loop gain constant irrespective of the rolling speed. The control system is therefore stabi lized by putting a correction circuit 13 in the control loop. A limitation is then given to the control gain due to the stable boundary of the control gain alphalbeing varied according to the material. Namely the stable boundary is changed by the deformation resistance Km of the rolled stock. In case of soft material the control gain alphal is comparatively stabilized even if taken larger, but it is apt to become unstabilized due to the rolling load difference PdF being widely varied by levelling in case of hard material and the control gain alphal cannot be made larger. The control gain alphal is therefore changed by the parallel spring constant Ml of the rolled stock.
