摘要： The novelty is that an assembly which processes solid organic substances incorporates: (a) a digesting tank which receives the organic solids in which the tank ferments the organic substances to compost before discharge; (b) a heat exchanger which is located outside the process tank, in which vapours and gases emitted from the process tank are condensed into a liq. for discharge. The heat exchanger is positioned with an intervening gap on the process tank wall, on that side from which compost is discharged. A blower fan adjacent to the tank directs air at one side of the heat exchanger. Part of the gas transferred from the tank is deodorised by an assembly located under the heat exchanger.

摘要： A single phase, full wave diode bridge circuit is connected with a chopper on its DC output side. An output voltage of the chopper is smoothed by a smoothing capacitor and thereafter supplied for a load. A current control apparatus forms a current reference signal which is synchronized with an AC voltage applied to the bridge circuit and has a magnitude corresponding to a current flowing through the load and produces a deviation signal between the current reference signal and an actual AC input current of the bridge circuit. The chopper is controlled in accordance with the deviation signal so that the AC input current follows the current reference signal, whereby the power factor and the waveform of the AC input current in the bridge circuit are improved.

摘要： PROBLEM TO BE SOLVED: To simplify the constitution to switch an ordinary operational action and an action except for ordinary operation by closing a power source in a condition where a switch to switch operation of an input control device is pushed down, and performing the action except for ordinary operation when a pushing-down condition passes by a prescribed time. SOLUTION: When a main body switch 7 is pushed down, a level signal convering means 21 outputs a level signal to a microcomputer 14, and the microcomputer 14 starts operation by its level signal, and judges operation mode switching or stopping. This main body switch 7 stops a vaccum cleaner every time when the switch is accepted in an ordinary using condition, and switches a strong mode, a medium mode and a weak mode of suction force in order, and repeats to return again to a stopping condition, but when a demonstration mode is started by the main body switch 7, the main body switch 7 is pushed down for a prescribed time or more at power source closing time. Therefore, a refuse quantity display of a small refuse quantity, a medium refuse quantity and a large refuse quantity can be periodically switched.

摘要： PROBLEM TO BE SOLVED: To satisfy power source higher harmonic restriction, to reduce the loss of a PWM converter and to save energy in an active filter controller where the current of the PWM converter is controlled so as to cancel higher harmonic current at a load side. SOLUTION: The controller is provided with a means for detecting instantaneous harmonic current at the load side by a current detecting equipment 11a so as to adopt it as a higher harmonic compensating current command ic*, a means 16 for detecting the sizes of fifth, seventh, eleventh and thirteenth higher harmonic current at a power source system side and the higher harmonic current restriction value setting means of respective ordinal numbers. A comparing means 17 successively reduce the amplitude of the higher harmonic compensating current command by changing compensation gain K within a range where a higher harmonic current detecting value at every ordinal number does not become more than a restriction value so as to execute an operation by weakening higher harmonic curren compensation. When the amplitude of the current command becomes zero, the comparing means 18 outputs an interrupting signal and a gate voltage to the PWM converter 3 is interrupted from an AND means 15.

摘要： PURPOSE:To realize positive stripping of coating without replacing a cutter by providing a mechanism for driving a cutter into a coating, and a mechanism for turning the cutter along the outer periphery of a wire. CONSTITUTION:When a main gear 2 turns in the direction (a), a cam gear 3 sustains current state because the rotating force transmitted thereto is lower than the holding force of a gear 4 and thereby only the main gear 2 is rotated. Consequently, a cutter 6 is shifted along a slide groove 18 in the main gear 2 and a spiral groove 17 in the cam gear 3 toward the center of a wire passing hole 11. When three cutters 6 are arranged at a constant angular pitch of 120 deg., a wire 8 is pinched at three point and thereby the wire 8 does not slip but moved uniformly in the direction of the core. When the cutter 6 is guided along the slide groove 18 through a right square part, the cutter can be used on four sides thereof upon abrasion of chipping of the edge. This mechanism realizes positive stripping of coating without replacing the cutter.
