Title: Washing method of filter of dust collector
Inventor: MURAYAMA TAKAO
IPC: B01D46/42
Filed: 1981-02-10
Abstract: PURPOSE: To execute a washing work of a filter in a very short time without disassembling a dust collector itself, by making a detergent spray and collide against a filter rotating at a high speed.  
     CONSTITUTION: From a detergent nozzle part 3, a detergent is made to spray and collide against a filter 3 which is rotating at a high speed. As a result, foreign matter adhering onto the surface of the filter 2, is peeled off directly, is repelled off to the outside, and simultaneously foreign matter which is gradually extracted into particles of the detergent is also scattered to the outside together with the particles of the detergent by rotating force, therefore, the washing work of a filter in a dust collector can be performed in a very short time. In this regard, as for the jetting direction of a detergent, when spraying is performed in the reverse direction to the rotating direction of the filter, kinetic energy of the detergent is redoubled, therefore, the washing is performed more effectively.

Filed: 1981-02-10
Abstract: PURPOSE:To simplify succeeding circuits which logically process pulses, by receiving pulses superimposed with DC components and introducing the pulses through setting one level of the pulses e.g. low level, to a predetermined potential. CONSTITUTION:A pulse (1) of a transmission signal SG is inputted to an input terminal W. This signal is at high level at VE and low level at VB.

The level of an output terminal Y is a voltage VDD at a terminal U. At the trailing of the pulse, the base of the TR4 is a voltage subtracting the pulse amplitude V1 from VBE of the TR4. Thus, the base of the TR4 is biased negative, the TR4 is cut off and the TR5 is conductive. Thus, the output of Y is at ground level of a terminal V.
