Title: Device for suction transportation of refuse
Inventor: FUJITA EIJI
IPC: B65F5/00
Filed: 1990-03-27
Abstract: PURPOSE:To improve the sanitary environmental by connecting plural refuse storage vessels and a reservoir tank of a vacuum car with communicating passages each having an opening and closing valve, and by repeating the suction cycle in each of the vessels communicated with each reservoir tank so as to operate the next vessels on the basis of elapsed time of the last cycle. CONSTITUTION:A vessel B1 and a reservoir tank 10 are made to have negative pressure by operating a suction device 20 through communicating a vessel, e.g. B1 with the reservoir tank 10 by opening an opening and closing valve E1 by means of a controller equipped on a vacuum car C. Then, refuse is sucked and carried into the reservoir tank 10 of the vacuum car by introducing secondary air A1 into the vessel B1 by means of a valve V1 of an introducing means F1. When pressure in the vessel B1 and the reservoir tank 10 is rased by this operation, the same cycle operation is repeated. As soon as the last cycle starts, elapsed time is measured. After the required time has elapsed, an opening and closing valve of the next vessel, e.g. E2 of B2, is opened and the valve E1 is closed.

Filed: 1990-03-27
Abstract: PURPOSE:To dispense with interlock ratio adjustment and deflection direction adjustment by providing an asymmetry correcting device at the center of a lens to be corrected, and integrating it with the lens. CONSTITUTION:A center electrode 50 is divided into eight, and the voltage Vc controlling the magnitude of a lens action in common with individual electrodes, the voltage correcting the axial drift, and the voltage for astigmatic correction are superimposed.
