Title: Reverse washing of membrane separation apparatus
Inventor: YOKOTA MINORU
IPC: B01D65/02
Filed: 1989-12-15
Abstract: PURPOSE:To improve reverse washing efficiency by making a tank airtight and taking out raw water from the inside of the tank to the outside and at the same time making air flowing in by keeping an inner plane of a separation membrane of a membrane set open to air at the time of reverse washing. CONSTITUTION:At the time of reverse washing, supply of raw water 4 through a flowing-in pipe 2 is stopped, a valve 22 is shut, and while a valve 23 of flowing-out pipe 3 is opened, a valve 24 of a branched pipe 27 is opened to air. A valve 25 of a gas discharging pipe 5 is opened, a wastewater pump 26 is started, and raw water in a separation tank 1 is discharged. In this way, the pressure of the separation tank 1 becomes lower than atmospheric pressure and the inside of flowing-out pipe 3 has atmospheric pressure and thus pressure difference is generated between the inside plane and outside planes of a separation membrane 12 and air flows in a flowing route 13 through the branched pipe and flowing-out pipe 3 and passes the separation membrane 12 to the outer plane. By this method, deposit are scaled off and driving cost is lessened.

Title: Sealing contact device
Inventor: TOGUCHI TAKEHIKO
IPC: H01H33/64
Filed: 1988-12-22
Abstract: PURPOSE:To improve the insulating property with a simple method by forming a tube through which a movable shaft is penetrated integrally with the same material as a trunk to form a sealing container, and providing a specific insulating distance between one end of the tube and the end at the movable contact side of the movable shaft. CONSTITUTION:A tube 33 through which a movable electrode 41 is penetrated and a trunk 32 are made in a unitary composition made of the same insulating material, and a circular projecting spring 36c is formed around a movable shaft 41b inside a shoulder 36b where the trunk 32 and the tube 33 are continued. As a result, an arc and a metallic spray of the arc generated when the contact is cut off never advance to the upper side, that is, crossing the projecting spring 36c, to the tube 33. Consequently, by making the distance between the inner periphery of the projecting spring 36c and the outer periphery of the movable shaft 41b in a distance necessary for insulation, the insulation between the movable electrode 41 and a fixed electrode 39 can be secured. The number of parts is reduced, the composition is simplified, and at the same time, the deterioration of the insulation and the voltage-resisting property can be prevented, consequently.
