Patent JP-S6013990-A (JP)
Title: Slurry pump
Inventor: SAKAI KENJI
IPC: F04B15/02
Filed: 1983-07-04
Abstract: PURPOSE:To prevent generations of pressure loss and noise of vibration and reduce the cost of the pump by a method wherein changeover of the flow of pressure oil in a main hydraulic pipe line, connected to a main hydraulic cylinder, is effected by the reversible changeover of a main hydraulic pump to make a changeover valve in the main hydraulic pipeline unnecessary. CONSTITUTION:When a hydraulic piston 101a arrives at the stroke end thereof, a valve driving changeover valve 26 is switched by the signal of a hydraulic piston position detector 27a and a suction valve 6 as well as a delivery valve 7 are switched. When the delivery valve 7 is switched from the side 5a of a concrete pump cylinder to the side 5b of the same, the valve driving changeover valve 26 becomes neutral temporarily by the signal of a concrete piston position detector 28b, the pressure oil discharging direction of the main hydraulic pump 1 is converted during the neutral condition and the main hydraulic pipeline 11b becomes delivery side while the main hydraulic pipeline 11a becomes suction side. According to this conversion, the hydraulic piston 101b, arrived at the left end by the reversal of the discharging direction of the main hydraulic pump 1, moves to the right side together with the concrete piston 501b and a delivery stroke starts its action.

Title: Liquefaction preventive work for sandy ground
Inventor: HANZAWA HIDEO
IPC: E02D3/08
Filed: 1983-07-04
Abstract: PURPOSE:To prevent the liquefaction of sandy ground by a method in which a hollow casing pipe having a cover to be opened or closed on its tip is driven into the sandy ground under vibration, gravels are charged into the pipe, and the pipe is drawn out while being vibrated. CONSTITUTION:A casing pipe 2 is driven into sandy ground G while being vibrated by a vibro-hammer 8. Gravels 9 are charged into the pipe 2 from a charging hopper 10, and the pipe 2 is drawn out while being vibrated by the vibro-hammer 8 to form a gravel column 13. The density of the ground G can thus be raised, the liquefying resistance of the sand itself can be raised, and the excessive void water pressures to be generated in the sandy ground G can be eliminated. The draining effect can therefore be improved.

Title: Room cooling and heating device
Inventor: TAKAI RYOICHI
IPC: F24F1/02
Filed: 1985-06-05
Abstract: PURPOSE:To obtain the room cooling and heating machine of low cost and simple type by a method wherein a casing, having first chamber opened in one surface and provided with an evaporator and second chamber opened in the other surface and provided with a condenser, is provided with a supporting means, supporting the opening surfaces to chamber walls switchably. CONSTITUTION:Refrigerant, compressed by a compressor 31, emits the heat thereof in the condenser 32 to the outdoor 25 and is condensed. Then, the refrigerant enters into the evaporator 34 through an expansion valve and deprives heat from air in a room 24 whereby the room 24 is cooled. Next, the casing 15 is pivoted about the vertical axis thereof by shafts 16, 17 provided on the upper and lower end faces of the casing 15 and whereby the opening surfaces toward indoor and outdoor sides are switched. Then, the compressed refrigerant provides the heat thereof to the inside of the room 24 through the condenser 32 and is condensed. Thereafter, the condensed refrigerant enters into the evaporator 34 through the expansion valve and deprives heat from atmosphere in the outside 25 of the room to heat the inside of the room 24. The room cooling and heating machine of low cost and simple shape may be obtained by switching the opening surfaces of the casing in such a manner.

Abstract: PURPOSE:To prevent the unnecessary starting and stopping of a storm sewage pump by controlling the opening and closing of an inflow gate and the rotating speed of the storm sewage pump on the basis of water level and the amount of rainfall, and providing a prescribed operating machine number control pattern. CONSTITUTION:When the measured values of a water gauge 1 in front of an inflow gate and a rain gauge reach regulated values or more, the inflow gate 2 is opened.

After the starting, the rotating speed is controlled, and the water level is set between the water level of the pump 8 and the general starting level of the pump 9. After a prescribed time, the control pattern is switched to a machine number control pattern in which the starting level of the pump 9 is set to a general value, and those on and after the third storm sewage pump 10 are set higher than the level rise value during the starting of the pump 9. Thus, a wasteful starting can be prevented.
