Title: Rolling mill for executing constant-pressure screw-down control, method for detecting amount of meandering and method for controlling meandering in pinch roll
Inventor: SUZUKI TAKASHI
IPC: B21B37/00
Filed: 1994-10-05
Abstract: PURPOSE: To prevent meandering with pinch rolls by taking the time depending variables of the detected values of roll gaps on the work and drive sides as a parameter to the amount of meandering and correcting rolling force so as to make the variables zero. CONSTITUTION: Bearing boxes 7 for supporting a lower buck-up roll 5 are in contact with screw-up cylinders 8, 9 on the work and drive sides. The moving amounts of these screw-up cylinders 8, 9 on the work and drive sides age detected with roll gap detectors 14, 15 on the work and drive sides and transmitted to a host CPU 16 as the detected values δ of roll gaps. In the host CPU 16, the detected values are converted into the time depending variables Δδ/Δt and converted into leveling forces Ft. Further, the leveling forces Ft are added to the rolling forces P on the work and drive sides before meandering and corrected rolling force directing signals are transmitted to rolling force setting devices 17, 18 on the work and drive sides so that the time depending variables Δδ/Δt become zero.  In the above-mentioned manner, corrected rolling forces are added to the screw-up cylinders 8, 9 on the work and drive sides and meandering is prevented.

IPC: F25B41/00
Filed: 1989-09-18
Abstract: PURPOSE:To prevent the generation of uneven flow of refrigerant, which is caused due to a bent part, and supply the refrigerant uniformly to respective evaporating tubes of an evapora tor by a refrigerant distributor by a method wherein a chamber, into which refrigerant flows from a refrigerant inflow passage, is formed on the extension of a refrigerant inflow vessel. CONSTITUTION:The pressure of refrigerant, flowing out of a liquid receiver 12, is reduced by a pressure reducing valve 1 and the flow amount of the refrigerant is controlled to a predetermined flow rate in accordance with a cooling load. The refrigerant, flowing out of the pressure reducing valve 1, flows into a pipeline 3 in the condition of two phases of gas and liquid, then, flows into the refrigerant inflow passage 5 of a refrigerant supplying passage 4 which is formed integrally with a refrigerant distributor 2, while the refrigerant flows into a chamber 7 once and is collided against the deep wall thereof, it is disturbed by the following refrigerant flowing thereinto continuously, and flows out of a refrigerant outflow passage 6 whereby the refrigerant is supplied to a refrigerant distributor 2 without generating any bias current. The refrigerant is distributed uniformly into the refrigerant distributing passages 2a of the refrigerant distributor 2 and the refrigerant of two phase condition of gas and liquid is supplied to respective evaporating tubes of an evaporator 9 by four pieces of pipelines 8 evenly whereby the title device may be operated under the most efficient condition. The refrigerant, passaged through the evaporator 9, is compressed by a compressor 10 and is condensed by a successive condense 11 whereby the refrigerant becomes liquid phase condition and is collected into the liquid receiver 12.

Title: Manufacture of thin film transistor
Inventor: YAOI YOSHIFUMI
IPC: H01L29/78
Filed: 1991-09-20
Abstract: PURPOSE:To form a semiconductor film to an island-like pattern without letting it pass through a complicated constitution by injection specific element ions to a region excepting a transistor element region of the semiconductor film and by carrying out a thermal treatment thereafter. CONSTITUTION:A resist pattern for shaping a polycrystalline Si film 3 to a thin film transistor is formed and O<+> is injected all over. The O<+> is an element ion for making a region excepting a pattern of the polycrystalline Si film 3 an insulator. After injection of O<+>, injection region of O<+> is thermally treated by a laser beam; thereby, the polycrystalline Si film 3 is oxidized in the O<+> injection region to form an SiO2 film 4. The polycrystalline Si film 3 is thereby patterned to a shape of a thin film transistor. Accordingly, an island-like pattern of a thin film transistor is formed of a semiconductor film not by a processing of etching but by processing of making a region excepting a pattern an insulator and a semiconductor film is not exposed at an end part of a pattern.

IPC: G02B7/28
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To automatically adjust the focus of a camera at high speed. SOLUTION: First an optical system is moved by a prescribed amount N towards a far FAR distance direction and based on an increasing/decreasing tendency of a level change in a high-frequency component, the succeeding moving direction of the optical system is decided (O-Q section). Then the optical system is moved at a high speed, the level of the high frequency component is changed from an increasing tendency into a decreasing tendency, and the optical system is moved at a low speed in the opposite direction at a point R the level is decreased just by a prescribed level α. Then after confirming that a position maximizing the level of the high frequency component, that is, a focal position P is passed by low-speed movement (after the arrival of a point S), the optical system is returned to the focal position P at high speed.

Title: Protection circuit for electrostatic thyristor
Inventor: MIYAGI HIDEO
IPC: H03K17/73
Filed: 1987-09-26
Abstract: PURPOSE:To prevent disabled turn-off of an electrostatic induction thyristor even when a steep anode current flows to the electrostatic thyristor by causing a current to flow from a gate side to a cathode side of the electrostatic induction thyristor when the applied voltage exceeds a prescribed voltage. CONSTITUTION:When a steep rush current IA flows between the anode and cathode of the turned-on electrostatic induction thyristor SI, a steep voltage is generated between the gate and cathode to give a current discharging a capacitor C2. However, when the voltage VCK between the gate and cathode exceeds a prescribed voltage, a voltage response element D is conductive to bypass the current ID, then it is possible to keep the charging voltage of the capacitor C2 to a prescribed voltage or over. The voltage requiring to turn off the electrostatic induction thyristor SI is not deficient. Thus, even when the steep anode current IA flows, the electrostatic induction thyristor is turned off surely.

Title: Method for filling up liquid chromatographic column with slurry with pressurized gas
Inventor: MORIMOTO SHINICHIRO
IPC: G01N30/56
Filed: 1992-08-20
Abstract: PURPOSE:To prevent the performance deterioration of a chromatographic column by bubbling after filling up the column with filler slurry by introducing a gas into the column upon completing the filling of the column so as to push out a solvent from the column. CONSTITUTION:A solvent filling up a chromatographic column 1 in advance is successively pushed out to a solvent receiving tank 4 by a filler slurry from a slurry tank 2. In the last stage of the filling of the column 1, the solvent is sprayed upon the internal surface of the tank 2 from a spraying device 7 so as to wash down the filler adhering to the internal surface of the tank 2 and the washed-down filler is fed to the column 1 together with the solvent. In a liquid draining process, a gas is continuously introduced into the column even after the slurry in the tank 2 is completely fed to the column 1 so that the solvent in the column 1 can be discharged to the tank 4. As a result, the column 1 becomes to contain a filler layer 10 and the gas only. Thereafter, an upper lid 8 for filling is exchanged with a liquid passing upper lid 9 for operation. When the lid exchange is carried on, the inside of the column 1 is opened to the atmosphere, but, since no solvent exists in the layer 10, the gas is discharged to the outside without bubbling.
