Title: Exhaust-valve driving system for water-cooled two-cycle engine
Inventor: IIO TOSHIMITSU
IPC: F01L7/12
Filed: 1979-10-17
Abstract: PURPOSE: To obtain correct timing for discharging exhaust gas, by transmitting pressure on the upstream side of a restriction and that on the downstream side of the restriction respectively to a pressure chamber and a compensating chamber formed in a cylinder for driving an exhaust valve, and thereby compensating variation in the pressure of cooling water due to its temperature change in the cylinder.  
     CONSTITUTION: As the amount of water discharged from a water pump 10 is increased along with rising of engine speed, pressure difference on the opposite sides of a restriction 11 is also increased since the velocity of water flow through the restriction 11 is increased. Resultantly, a piston 9 is shifted to a position where the force of spring 16 balances with the pressure difference and turns an exhaust valve 8 for advancing the timing for discharging exhaust gas. Here, since variation in the pressure of cooling water caused by its temperature change is transmitted to both of a pressure chamber 15 and a compensating chamber 17 having an area substantially equal to that of piston 9, variation of pressure acted to the piston 9 can be compensated. Thus, piston 9 can be moved in response to the velocity of cooling-water flow, i.e., the engine speed correctly.

Title: Safety door for elevator door
Inventor: FUJITA MASAO
IPC: B66B13/26
Filed: 1991-06-05
Abstract: PURPOSE:To provide a safety device for an elevator door which improves safety of passengers at an elevator hall by detecting it by a photo sensor, located approximately to the upper central part of a cage, that visible beams emitted only during a given time are shielded by an object. CONSTITUTION:A photo sensor 23 is composed of a photo electric converting part 25, an amplifying part 26, and a signal processing part 27. The signal processing part 27 compares a detecting signal from the amplifying part 26 with a reference signal responding to a door position. When a difference therebetween is below a given level, a signal by means of which detection of an object is represented is not outputted. When an object, such as passengers, enters and exits, visible light 22 within a detecting range is shielded and a detecting signal from the amplifying part 26 is decreased to a value lower than a reference signal by a given level or more, whereby the signal processing part 27 outputs a signal, by means of which detection of an object is represented, to an elevator control device 24. The elevator control device 24 outputs a door reverse command to a motor drive control part 29 and controls operation of the door without exercising an influence during closing operation of the door, whereby collision is prevented from occurring.

Abstract: PURPOSE: To prevent slippage of a detection position by switching the rotation direction of a tone arm to cause it to decsend to the playing position after rotating the tone arm at the completion of playing up to a prescribed position of a record in case that an auto-repeat operation is set.  
     CONSTITUTION: Horizontal control motor 10, vertical control motor 11 and horizontal position detector 12 are provided for tone arm 5. Horizontal control motor 10 consists of a rotor, which consists of a coil wound around bobbin 13, and yoke 15. A magnet magnetized in the thickness direction is provided in the lower part of the yoke. In case of auto-repeat, tone arm 5 is returned to P 2  and is stopped after causing it to go too far up to position P 4  when tone arm 5 is returned in the arrow 5 direction, thus preparing for the next playing. Thus, tone arm 5 is prevented from slippage dependent upon hysteresis of the detector, etc., and is always stopped in correct position P 2 .

Title: Injection molding method and injection molding device
Inventor: SAKAI TSUTOMU
IPC: B29C45/50
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To realize a gentle changeover to a dwelling process without causing an abrupt pressure rise by a method wherein the power in the process previous to the dwelling process is made to be constant by controlling a resin injecting means. SOLUTION: A servo driving part 1a is controlled so as to make the power in the process previous to the dwelling process or in the charging process and the compressing process of an injection molding process. Concretely, an injection speed is calculated by dividing a set power by the value of pressure, which is prepared by feeding the pressure data of resin obtained with a pressure detector 2 to a divider 4. The injection speed is compared through a limiter 5 with the actual injection speed obtained from an injection speed detector 3 and amplified with a summing amplifier 6 and fed to the servo driving part 1a. On the other hand, the pressure data sent from a pressure detector 2 is compared with a set upper limit pressure and, through a summing amplifier 7 and a limiter 8, fed to the servo driving part 1a.  The changeover to the dwelling process occurs when the pressure data reach the upper limit pressure. As a result, the injection speed and the pressure hold an inversely proportional relationship, resulting in generating no overshoot of the pressure.

IPC: H01J9/20
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a coating film, and to prevent the generation of a crack in a frit seal part, by heating the carbon, which is coated on a surface of a cathode-ray tube, so as to previously discharge the gas inside of the carbon in a process before a sputtering process using the process gas. SOLUTION: A funnel part 3 of a cathode-ray tube is coated with the carbon 9a as an outside conductive film, and since the carbon is a porous material, the carbon 9a absorbs a large quantity of gas. Plural panel heaters 21 are used so as to raise the temperature and so as to remove the absorbed gas in the carbon, and spattering is performed thereafter so as to restrict the generation of discharge gas during the processing. Quality of a thin film to be coated is thereby improved. As a means for heating the carbon, a ceramics far infrared radiation heater, of which temperature can be controlled, is used, and obliquely arranged so that the heat is not directly applied to a neck part 5 of the cathode- ray tube.  The far infrared radiation heater is used so as to evenly heat the whole of the cathode-ray tube with a conventional heater for heating the panel part 2, and the generation of crack of a frit part is prevented.
