Title: Variable displacement vane pump
Inventor: IDETA YASUFUMI
IPC: F04C14/22
Filed: 1982-12-21
Abstract: PURPOSE:To prevent any drop in the discharge pressure by air suction even in case pump parts are worn one another due to use for hours as well as to aim at a distinct improvement in their durability, by forming an interspace between a cam ring and a housing into an oil reservoir construction, while installing a drain in position higher than a suction port. CONSTITUTION:In an interspace between a cam ring 1 and a housing 10, cam ring turning chamber 11 is formed and which turns to an oil reservoir construction for lubricating oil in structure, while a drain 12 is installed in the topmost part of the chamber 11, and the drain 12 is situated higher than a suction port 4. With this method, the cam ring 1 becomes such a structure as being uncontacted with the outside air directly irrespective of eccentricity. Therefore, because of use for long hours, even in case pump parts are worn one another whereby a side clearance grows large, lubricating oil is filled up in the cam ring turning chamber 11 so that the cam ring 1 is in no case contacted directly with the outside air, thus any drop by air suction from the suction port 4 and the occurrence of an unusual noise both can be prevented.

Title: Method for controlling water sprinkling in crushed substance storage area
Inventor: SUZUKI SHOGO
IPC: B05B12/12
Filed: 1986-09-24
Abstract: PURPOSE:To surely prevent the generation of heat or dust from a crushed substance such as coal by effectively performing water sprinkling, by setting the presence of a rainfall and the quantity thereof to a water sprinkling condition in addition to wind velocity. CONSTITUTION:CPU22 successively takes in the meteorological data detected by measuring instruments WM1-WM8 at every predetermined time and the dust data detected by dust sensors SA-SD to store said data in RAM27. Each control mode such as a meteorological mode or a dust mode is judged and the water sprinkling control of water sprinkling guns A1-A20, B1-B20 is performed on the basis of the corresponding data. Herein, when control is performed on the basis of the meteorological data, it is judged whether it is raining and, when there is no rain, water sprinkling is performed at the time of such a condition that wind velocity is set one or more and, when there is rain, water sprinkling is performed at the time of such a condition that rainfall is set or less and wind velocity is set one or more. By this method, the generation of dust or heat is surely prevented without wastefully sprinkling water.

Title: Logical circuit device
Inventor: NISHIMURA TAKASHI
IPC: H03K19/086
Filed: 1982-12-22
Abstract: PURPOSE:To improve the delay time by removing an emitter follower resistor, connecting a new transistor (TR) to an emitter follower TR, and controlling the current amount of the emitter follower TR depending on the difference between a reference potential and an input potential. CONSTITUTION:A base potential of a TRQ6 is changed in phase with the change in the input logical level applied to input terminals 11, 12, 13. Then, a value of a resistor R4 set properly allows the TRQ6 to be made conductive when an input potential VIN is at a high logical level VH and to make nonconductive or equivalent state when at a low logicl level VL. As a result, when the input potential VIN transits from the level VH to the level VL, since input TRQ1-Q3 are nonconductive, the TRQ6 becomes a state close to nonconductivity, most of the supply current from the emitter follower TRQ5 flows to a load capacitor CL, thereby improving the delay time at the leading of the NOR output. When the input potential transits from the VL to VH, since the charge in the load capacitor CL is extracted directly through the TRQ6, the delay time at falling is improved.

Title: Long-life cold accumulating agent
Inventor: UMEMOTO MASAO
IPC: C09K5/06
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To remove a semi-heat-insulating container at freezing to let it perform the freezing in a short time, and mounting the semi-heat-insulating container at use thereby enabling it to preserve a frozen body for a long time, by making the container to store the frozen body a semi-heat-insulating container, and providing this semi-heat-insulating container mountably. SOLUTION: In case that a freezing agent which has a peculiar temperature of, for example, -10 to -18 deg.C is put in a semi-heat-insulating container and that it is let alone at a room temperature (15-30 deg.C), the temperature of the external surface goes up, and cold insulator at ice temperature comes to -5 deg.C to -1 deg.C or 0 deg.C. Putting such a semi-heat-insulating container in a heat insulating box of foaming styrene or the like will enable the frozen body put in the semi- heat-insulating box to be preserved for a long time at a specified temperature (-10 deg.C to -18 deg.C) since the temperature of the external surface is -10 deg.C to -18 deg.C. But, if the user seeks to freeze a freezing agent in a freezer as it is in the semi-heat-insulating container, it takes a long time, so at the time of freezing in a freezer, he should take out the semi-heat-insulating container and put freezing material in a freezer to enable it to be frozen in its early stage, and put it in the semi-heat-insulating container again after freezing.

Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To maximumly utilize the capacities of a compressor and a fan motor without causing people around a dehumidifier to feel unpleasant due to noise and vibrations. SOLUTION: When people stay around a dehumidifier, the dehumidifier is operated in a noise- and vibration-cut state by reducing the numbers of revolutions of a compressor 29 and a fan motor 32. When the person leaves the circumference, the numbers of revolutions of the compressor 29 and motor 32 are increased. Since the compressor 29 and motor 32 are operated at their maximum capacities by increasing the numbers of revolutions in the above- mentioned way when no person stays in the circumference of the dehumidifier, the capacities of the compressor 29 and motor 32 can be utilized maximumly.
