Title: Isolation valve in single crystal pulling device
Inventor: IWASAKI ATSUSHI
IPC: H01L21/208
Filed: 1989-03-24
Abstract: PURPOSE:To prevent damage of sealing function even in rise of a shutter by internal pressure of chamber by forming the shutter into an inverted saucer shape, providing an inner peripheral part of shutter or an outer peripheral of top opening part of the chamber and making a side sealing method. CONSTITUTION:An isolation valve 10 is equipped at the top opening part of a chamber of a single crystal pulling device. Then, a shaft 13 is vertically movably and rotatably inserted into a main body 11 of the valve 10, one end of an arm member 14 is fixed to a middle part of the shaft 13 and an inert saucer-shaped shutter 15 is attached to the under surface of the other end. Further a sealing ring 17 is laid at the inner peripheral part of the shutter 15 or an outer periphery of top opening part of the chamber. Then since the shutter 15 is dropped and the sealing ring 17 is crushed when the top opening part of the chamber is closed, side sealing function is attained by the sealing ring 17 and leakage of inert gas from the valve 10 is surely prevented.

Title: Flusher for flow control valve
Inventor: WAKIMOTO TSUNEO
IPC: F16K3/30
Filed: 1983-04-21
Abstract: PURPOSE:To prevent a flow of foreign substances removed by flushing from going to the downstream, by installing a blade member projectingly in the lower part of an inner circumference of the peripheral wall of a valve body as well as installing a small chamber being coupled with a drain pipe, in the circumference of the valve body. CONSTITUTION:A lot of taper-form small holes 11 turning into a large diamter at th circumferential side are made up at the peripheral wall of a valve body, and plural blade members 14 are projectingly installed in the lower part of an inner circumference of the peripheral wall of the valve body 10 at regular intervals in a circumferential direction. And, a small chamber 17 being coupled with a drain pipe 18 is formed up in the circumference of the valve body 10, and a stop valve 19 is installed in the drain pipe 18. In time of flushing these small holes, when the stop valve 19 is opened in a state that a flow control part 12 is situated in an inflow chamber 7, a fluid from an inflow port 2 enters inside the valve body 10 by way of these small holes 11 and further enters the small chamber 17 through these small holes 11, flushing these holes clean, and then is discharged outside by way of the drain pipe 18. At this time, the valve body 10 is rotated by the blade member 14 whereby these small holes can be flushed clean over the whole circumference and, what is more, foreign substances will not flow into a pipe line at the downstream at all.

Title: Heat pump device driven by stirling engine
Inventor: FUJITA YOSHINOBU
IPC: F25B47/02
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the rotational frequency of an engine from being rapidly increased during a defrosting operation, by lowering both the heating temperature of a working gas in the engine and the rotational frequency of the engine when a condition for defrosting is detected during a normal operation, and starting the defrosting operation when the heating temperature and the rotational frequency are lowered to predetermined values. CONSTITUTION:A rotary shaft of a compressor 15 in a heat pump 14 is connected to an output shaft 10 of a Stirling engine 1 through a clutch 13. The heat pump 14 comprises the compressor 15, a four-way valve 16, an interior heat exchanger 17, an expansion valve 18 and an exterior heat exchanger 10. When a condition for performing a defrosting operation is detected by a controller 20, the controller 20 controls a solenoid valve in a pressure-controlling mechanism 7 while monitoring the temperature of a heat exchange tube (the heating temperature of a working gas) in a high-temperature heat exchanger 3 through a temperature sensor 22, thereby controlling the pressure of the working gas and lowering the rotational frequency of the engine 1. With the defrosting operation thus started after the output of the engine is sufficiently lowered, the rotational frequency is prevented from being rapidly increased due to a rapid lowering in the load on the engine upon the start of the defrosting operation.

Title: Web winder
Inventor: YUKI KOICHI
IPC: B65H23/24
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a web winder free of the risk that the air is included in a web roll or the web in the outer layer of the web roll slackens to a large extent, and capable of lessening occurrence of the loss in paper. SOLUTION: A web winder configured so that a web W running via a reel drum 2 is wound on a rotating reel shaft 1 into a web roll R, is equipped with a sealed box 11 to enclose air-tightly the reel drum 2 and the web roll R under winding operation and an air exhausting device 12 to exhaust the air from the seal box 11 to outside. This constitution decreases the amount of air intruding between web layers of the web roll R from the nip part N where the reel drum 2 is in contact with the peripheral surface of the web roll R. Accordingly, since the amount of air expanding within the web roll R is decreased, the slack of the web W in the outer layer of web roll R is lessened to lead to a decrease in the amount of the loss in paper.

Abstract: PURPOSE:To form a decorative coating film excellent in adhesion with a topcoating film by coating part of the surface of a specific cured topcoating film with a decorative coating compsn. obtd. by adding a phosphoric ester to a specific two-coating compsn. CONSTITUTION:Part of the surface of a cured topcoating film having a static glass transition point of 60-130 deg.C t is coated with a decorative coating compsn. mainly comprising a hydroxylated resin (e.g. a polyester polyol or an acrylic polyol), a polyisocyanate compd. (e.g tolylene diisocyanate or diphenylmethane diisocyanate), and a phosphoric ester (e.g. monoethyl phosphate) in such a manner that a decorative coating film is formed in a shape of lines, characters, or patterns. Since the resin reacts easily with the isocyanate compd. to crosslink at a room temp., they are stored separately and mixed just before they are used. The ester is pref. premixed into the ester and/or the isocyanate compd. The addition of the ester improves the adhesion between the topcoating film and the decorative coating film.

Title: Local dryer

IPC: E03D9/08
Filed: 1994-04-11
Abstract: PURPOSE:To damp the sound of a fan motor and detect an operational failure surely by interposing a damping resistor in series with a fan motor and a compensation resistor in parallel with the damping resistor. CONSTITUTION:In a local drying device provided with a hot air drying device, there is provided a control device which detects a current value flowing in a fan motor 9 and determines as an operational failure when the detected value exceeds a specified value or fails to exceed the value. In this device, a damping resistor R1 interposed in series with the fan motor 9 is designed to 1 imit the current to the fan motor 9. In the same manner, a compensation resistor R2 interposed in parallel to the damping resistor R1 is adapted to keep the current flowing in an operational failure detection circuit 15 substantially at the same level to the current flowing before the damping resistor R1 is inserted. As a result, the current flowing in the fan motor 9 is reduced so that the rotary speed of the motor 9 may be lowered, thereby accomplishing a desired sound damping effect. What is more, this construction makes it possible to detect a locked state of the motor 9 or such failures as brush wear out without reducing no current flowing in the operational failure detection circuit 15.
