Title: Sealed type filter medium washing and filtering device
Inventor: MOCHIZUKI TAKUO
IPC: B01D29/62
Filed: 1980-11-11
Abstract: PURPOSE: To circulate and wash filter media efficiently and permit the use of raw water for washing of the filter media by providing a centrifugal separating chamber to the body of a sealed filter tank, and circulating and washing the filter media by using a jet pump.  
     CONSTITUTION: When the need for washing filter media arises, the stop valve 16 of a filter medium suction port 2 and the valve just before a jet pump 14 are opened, and the valve of a raw water inflow pipe 5 is closed. Then, raw water is injected from the jet pump 14 into a circulation passage 13 for washing and this is discharged into a centrifugal separation chamber 8. The stains separated from the media are discharged together with the media into the direction tangential to the inside wall of the chamber 8. Further, the filter media of large specific gravities settle and the suspending stains gather in the central part thereof and are returned to a raw water tank T through a water discharge port 12 then through a washing water discharge pipe 11 by the effect of the pressure in the tank, so that they are settled and are used as the water to be filtered again.

Title: Apparatus for controlling amount of injection from injection nozzle
Inventor: EEBUARUTO KIRE
IPC: B05B1/30
Filed: 1989-06-23
Abstract: PURPOSE: To steplessly adjust the outflow rate of a nozzle with a simple type and to stabilize discharge output and spraying degree by making a diaphragm opening regulatable for the purpose of flow rate adjustment and making it possible to automatically change the position of the valve member of an outlet valve by the axial relative movement of a control piston with respect to a control sleeve. CONSTITUTION: A medium is sucked and compressed into a pump chamber 6 by a plunger 5 upon operating of a discharge pump 2. When large force is acted on the outlet valve member 13 by a return spring 38, the outlet valve 11 opens and the medium flows into a discharge chamber 10. The medium arrives at the interior of an inner chamber 22 of an adjusting member 21 through the diaphragm opening 33 of the control piston 32. Next, the piston 32 is further moved to a left side and the opening 33 is closed by the sleeve 31. The pressures in the chambers 6 and 10 are increased and a high pressure is generated in the medium in the inner chamber 22, by which the medium is supplied. Next, the medium discharged into the inner chamber 22 is rapidly injected under the high pressure in the state that the opening 33 is closed and the outlet valve 11 is opened.  The control of the injection medium quantity of the injection nozzle 14 is executed by varying the position of the sleeve 31 with the adjusting member 21.

Firstly, the processor 1 sends out the signal of the data transfer instruction under execution to an output line (d), and also, sends out the transfer origin address to an output line (e). The control circuit 23, when receiving the signal of the data transfer instruction under execution and a write instruction, sets the data buffer 24 at a non-output state, and also, controls the register 22 at an output state. The memory 21 receives the transfer origin address via an input line (h), and also, receives the data via an output line (j). Thereby, the data transfer time can be shortened.
