摘要： In a power conversion system, a DC voltage of a DC power supply is converted into a predetermined high-frequency voltage by an inverter, and a high-frequency low voltage generated from the inverter is converted into a high-frequency high voltage by a transformer. A high-frequency high voltage generated from a secondary winding of the transformer is converted into a predetermined low-frequency voltage by a frequency changing circuit. The commutating operation of the frequency changing circuit is performed by a control circuit in response to the output current of the frequency changing circuit and in synchronism with the starting time of the short-circuiting prevention period of the inverter. As a result, the converted output of the power conversion system is prevented from decreasing.

摘要： A switching power supply, in which a series circuit consisting of a primary winding of a transformer and a controllable switch is connected with a DC power source and a secondary winding of the transformer is connected with a first voltage source outputting the voltage developed across the secondary winding during the on-period of the controllable switch and a second voltage source storing the exciting energy of the transformer during the off-period of the controllable switch by using the exciting inductance of the transformer as a current source, a series circuit consisting of the first and the second voltage sources being connected with a load. Owing to this construction, even if voltage-current characteristic of a load having constant voltage characteristic, such as a magnetron, vary due to variations in the temperature, etc., the output voltage is automatically compensated and a stable electric power can be supplied to the load.

摘要： A power supply apparatus for a resistance welder has an inverse-parallel thyristor circuit for constrolling the welding current. One of thyristors connected in inverse-parallel relationship is turned on by a first signal whose reference phase is established by a synchronizing signal which is based on a voltage wave form of an AC power source and the other thyristor is turned on by a second signal whose reference phase is established by a signal which is delayed half a period of the voltage wave form with respect to the first signal, so that integrals of positive and negative halves of the output voltage wave form of the inverse parallel thyristor circuit can always be made equal.

摘要： A spinning apparatus for a fasciated yarn is provided which comprises a fiber-opening means provided with a combing roller, a fiber-collecting means including an inlet member and a rotor, a twist-imparting means consisting of an air nozzle, and a yarn take-up means. A sliver opened by the combing roller is fed to the interior of the rotor through the inlet member. Since the rotor and the inlet member rotate reversely to each other, the fibers are evenly distributed on an inner surface of the rotor. An intermediate yarn drawn out from the rotor is supplied to the air nozzle under an overfeeding condition, whereby a good fasciating effect is imparted to the resultant yarn by a vortex. Prior to feeding the yarn to the air nozzle, the yarn may be drafted between two pairs of rollers. The apparatus is easy to maintain because a roller drafting means having an apron which rapidly wears due to high-speed processing is not utilized.
