Abstract: PURPOSE: To simply perform starting and stopping of a siphon pipe for backwashing,  by connecting the siphon pipe to water tank, and actuating the siphon by the water  head difference obtained by discharging water from the water tank and sucking up the  water to the tank by the negative pressure of the siphon.  
     CONSTITUTION: Raw water is fed into a water tank 19 to the water level A from a  manual valve V 5  by closing an automatic valve V 2  and opening a manual valve V 3 .  Next when automatic valves V 4  and V 3  are closed and automatic valves V 1  and V 2   are opened, the water in the tank 19 is discharged from a sucking and discharging  pipe 23 rapidly, and the air in a siphon pipe 5 for backwashing is sucked into the  tank 19 through a communicating pipe 20 and then the siphon pipe 5 is actuated, consequently the water in a filtering basin 3 is discharged from a chamber 13 into which  exhaust water flows after backwashing to a said water staying channel 16. On the  other hand, the water level in the tank 19 is lowered to the level D, but the water in  the channel 16 is sucked up into the tank 19 through the pipe 23 by the negative pressure generated in the upper part of the siphon pipe 5 while keeping the valves V 1  and  V 2  open, and when the water level in the tank 19 rises up to the level A, the valve V 2   is closed by a water level detector 25.

Title: Program shutter device
Inventor: NAKAI MASAAKI
IPC: G03B17/18
Filed: 1978-04-18
Abstract: PURPOSE: To enable program photography, by changing the program to a proper position when the calculated aperture value Av and exposure time value Tv reach out of the coupling range of the exposure control function or the camera-shake limit.  
     CONSTITUTION: A program shutter functions by controlling the exposure according to the Av value and Tv value stored in recording circuits 17, 18. A gate 11 compares the result of operation,  Av'=Av-β, with the open aperture value Avo in a comparator circuit 12, and is opened while Avo<Av', thereby sending the noncoincidence signal of the comparator circuit 16 into an agrument β setting circuit 6. A gate 15 compares the inverted signal of the output of the comparator circuit 12 or Tv'=Tv-α with the output Tvh of a camera-shake limit value setting circuit 10, and is opend while Tvh<Tv', thereby sending the noncoincidence signal of the comparator circuit  16 into an argument α setting circuit 8. Thus, as the program starts from the minimum aperture diameter maximum shutter speed and moves to the lower exposure value side until the shutter s peed reaches the camera-shake limit, the shutter speed is fixed and only the aperture is being opened until fixed at the open aperture. Then, the gate 15 is opened again, and the shutter speed is changed again toward the lower side.

Abstract: PURPOSE:To prevent the generation of a high bearing at the tip of a vane during the restarting of operation as a reverse flow is prevented from occurring during the stop of operation. CONSTITUTION:A core case 51 having an oblong hole 55, a valve body 56, a spring 57 through the force of which the valve body 56 is pushed in an upward direction, a check valve 50 consisting of the stopper 60 of a valve body 51 are arranged in the suction chamber 19 of a gas compressor. A communication hole 71 with a diameter of 1-2mm to intercommunicate a suction port 21 and the suction chamber 19 is formed in the valve body 56. During operation of a gas compressor, the valve body 56 is pressed down by means of refrigerant gas, and the refrigerant gas is caused to flow through the oblong hole 55 to the suction hole 19 after the flow of it through the suction port 21. When operation is stopped, the valve body 56 is pushed up to a position above the oblong hole 55 through the force of the spring 57 to prevent the occurrence of the rapid reverse flow of high temperature high pressure refrigerant gas. Since a pressure difference between pressures in the suction port 21 and a high pressure chamber is decreased through gentle reverse flow generated by the presence of the communication hole 71, the bearing of a vane during restarting is lowered.
