    摘要: A forward power converter with a self-excited synchronous rectifying circuit makes use of the self-excitation function of a transformer to generate electric energy at a secondary side winding coil of the transformer, hence controlling an n-channel FET to accomplish synchronous rectification. In the synchronous rectifying circuit, the drain of the n-channel FET is connected to an end of the secondary side of a first transformer, the source of the n-channel FET is connected to a positive end of a flywheel diode, the negative end of the flywheel diode is connected to the other end of the secondary side of the first transformer, a control end of the n-channel FET is connected to an end of an induction coil via a resistor and a capacitor, and the other end of the induction coil is connected to the source of the n-channel FET.

    摘要: First and second three-phase inverters having self-diagnosing circuits are connected to three-phase windings of a three-phase double-winding type motor, respectively, and first and second servo controllers having self-diagnosing circuits are connected to the three-phase inverters, respectively. When an abnormality occurs in the three-phase inverter or the servo controller, the occurrence of the abnormality is signaled to the servo controller. When abnormality occurs in the three-phase inverter or the servo controller, the occurrence of the abnormality is signaled to the servo controller, thereby stopping rotation of the motor.

    摘要: A heat exchanger made of plastic has flow channels for guiding two fluids countercurrently. The heat exchanger includes a cover part; an intermediate layer that at least partially forms the flow channels; and a trough part. The intermediate layer comprises (1) a flow channel for a first fluid comprising channel sections that are spaced apart from one another and (2) a second flow channel comprising opposite flow sections on back of the channel sections for a second fluid guided in an opposite direction from the first fluid. The wall areas that separate the channel sections and opposite flow sections are heat transfer membranes. The cover part and the trough part are connected tightly with the intermediate part, and the intermediate layer is a single piece. The heat exchanger can be used for room ventilation with heat recovery or air conditioning.

    摘要: Apparatus for molding objects from heat-softenable material which may include a plurality of molds, means for continuously supplying heat-softened material for the molds, and means for distributing heat-softened material from the supplying means to each of the plurality of molds. The heat-softened material supplied is removed for recovery, when the distribution of the heat-softened material is interrupted, by extendable-retractable means normally retracted to prevent interference with the distribution of the heat-softened material to the molds. The distributing means is positioned in a predetermined disposition with respect to the supplying means before the extendableretractable means is extended to receive and recover heatsoftened material. Removal and recovery of the heat-softened material may be initiated in response to the coincidence of an interruption of distribution of the heat-softened material and to the location of the distributing means in the predetermined disposition with respect to the supplying means.
