IPC: H02M7/12
Filed: 1990-09-10
Abstract: PURPOSE:To increase the power factor of a power source greatly and to downsize and lighten a device, by controlling the output current of a 3-phase rectifier circuit so as to be a direct current of constant amplitude, even when a single 3-phase rectifier circuit and a single booster chopper circuit are used. CONSTITUTION:When the output power of a motor 10 is constant, if the DC voltage Vdc of a capacitor 3 is controlled so as to be constant, the average value Idc of the input current of an inverter 9 becomes an approximately constant direct current, the output current Ix of a rectifier circuit 2 becomes a direct current too, and the power factor of the power source becomes comparatively large. Next when the load of the motor 10 increases suddenly, a capacitor current (ic) flows to discharge, so the DC voltage Vdc decreases. As a result, the gate-on period of a switching power element 5 becomes longer, energy stored in a DC reactor 4 is transferred to a smoothing capacitor 3 through a block diode 6, the DC voltage Vdc rises and becomes approximately equal to the same value as a voltage command V'dc.

Title: Cleaner for flow-controlling nozzle in combined, small-sized treating and purifying tank
Inventor: SUZUTA YASUTO
IPC: C02F3/00
Filed: 1987-09-25
Abstract: PURPOSE:To make it possible to automatically suitably clean the inside of an inlet nozzle, by providing a brush for cleaning the inlet nozzle such that said brush integratedly moves with the movement of a float which is floating on the surface of a liquid in a prefiltering tank. CONSTITUTION:A liquid in a prefiltering tank 1 flows through an inlet nozzle 6, an inlet tube 7, a transition tube 5 and an outlet tube 11 into a tank 2 for exposure to air, so that the water level in the tank 1 is normally kept stable between A and B. However, if the inlet nozzle 6 is clogged or when washings etc. are discharged at a time, the water level in the prefiltering tank 1 increases rapidly. For example, where the water level has changed to between C and D, the liquid in the tank 1 flows through a by-pass tube 10 into the tank 2 for exposure to air. At this time, a float 12 floating on the surface of the liquid in the tank 1 ascends and descends with the change in the liquid surface level, whereby a brush 14 of a shaft 13 attached to this float 12 moves while rubbing the inner surface of the inlet nozzle 6. As a result, the inner wall surface of the inlet nozzle 6 is suitably cleaned by this brush 14, thereby preventing the clogging of the inlet nozzle 6 from occurring.
