摘要： Diclosed are a fluid mixing element in which at least one helical shaft provided with at least one helical groove on an outer peripheral wall thereof throughtout its length is inserted in a cylindrical passage tube provided with at least one helical groove on an inner peripheral wall thereof throughout its length.According to the mixing element of the present invention, the fluid supplied into the mixing element flows partly along the helical groove formed in the passage tube and partly along the helical groove formed on the helical shaft to produce the turbulent mixing of the fluid in the mixing element. When the fluid flows through the helical grooves formed in the passage tube and on the helical shaft of the mixing element, the phase transfer is also carried out at planes perpendicular to the flow direction by inertia of the fluid. Accordingly, the fluid in contact with the helical grooves and the fluid out of contact therewith are replaced with each other in series. The mixing is further effected by division of the fluid in series at each of many contact portions of the passage tube and the helical shaft.As a result, the fluid mixing efficiency can be improved. The number of the mixing elements is therefore reduciable, when the plural mixing elements are connected to each other to form the mixer, and in addition, the time required for mixing in the mixer is also reducible.

摘要： One of a plurality of voltages is adapted to be applied to power supply terminals (2a, 2b, 2c). A rectifying circuit (6) rectifies the applied voltage and develops a rectified voltage between the output terminals (6a, 6b) thereof. Inverters (16a, 16b) are connected into one of a plurality of inverter connections between the rectifier output terminals (6a, 6b) in response to one of a plurality of inverter connection indicative signals. The inverter connections are set to correspond to respective ones of the plurality of voltages, so that a predetermined voltage can be applied to each inverter whichever one of the plurality of voltages is applied to the power supply terminals. An inverter connection indicative signal generating circuit (34) is manually operated to generate a desired one of the inverter connection indicative signals. A thyristor (8) is disposed between the rectifier output terminals (6a, 6b) and the inverters (16a, 16b). When one of the plurality of voltages is applied to the power supply terminals, a voltage detecting circuit (38) generates an inverter connection indicative signal corresponding to the voltage applied to the power supply terminals. A judging unit (26d) determines whether or not the inverter connection indicative signals from the voltage detecting circuit (38) and the inverter connection indicative signal generating circuit (34) match. When the two signals match, a thyristor control unit (26a) provides a CLOSE signal to the thyristor (8). When the two signals do not match, an alarm circuit (42) is activated.

摘要： A power supply apparatus for use with arc-utilizing apparatuses includes a plurality of power supply blocks (2a, 2b) of the same capacity. Each power supply block (2a, 2b) includes an input-side rectifying circuit (4a, 4b), an inverter (10a, 10b), a transformer (12a, 12b), and an output-side rectifying circuit (18a, 18b). The inverter (10a, 10b) is controlled by a control circuit (30a, 30b) in such a manner that high-frequency current flowing the inverter (10a, 10b) or current flowing through the output-side rectifying circuit (18a, 18b) can correspond to a reference signal provided by a reference signal generator (34a, 34b). The outputs of the output-side rectifying circuits (18a, 18b) of the power supply blocks are connected in parallel with each other. The values of the reference signals generated by the reference signal generators (34a, 34b) are made always equal by the action of equipotential lines (40, 42).

摘要： A power supply unit includes an input-side rectifying circuit (4), an inverter (8) and an output-side rectifying circuit (12), which include power semiconductor devices. The power supply unit is powered during a powering period, and the powering is interrupted during a pausing period. The powering and pausing periods alternate. A fan (18) is driven during each powering period to cool the power semiconductor devices. A temperature detector (30) measures the temperature of the power semiconductor devices and develops a measured-temperature representative signal. A setter (38) produces a reference value, which decreases over the pausing period from the measured-temperature representative signal at the beginning of the pausing period to an intended-temperature representative signal representing the temperature to be attained by the power semiconductor devices at the end of the pausing period. The reference value is prepared from the measured-temperature representative signal at the beginning of the pausing period, the intended-temperature representative signal, and the length of the pausing period. An error amplifier (36) and a fan control unit (22) control the rotation rate of the fan (18) to make the measured-temperature representative signal track the reference value.

摘要： A casting apparatus has a melting pot (4) in which pieces of metal (8) to be melted is placed. A RF induction heater coil (10) is disposed in association with the melting pot (4) to heat the metal pieces (8). An inverter (18) supplies the coil (10) with high-frequency power to melt the metal pieces (8) in the melting pot (4), and the resulting molten metal is poured into a die (6). A control unit (36), after all of the metal pieces (8) having various sizes and shapes are melted, causes the operation of the inverter (18) to continue for a first time period and, after that, to suspend the operation of the inverter (18) for a second time period so that the heating can be stopped. After that, the control unit (36) causes the inverter (18) to resume its operation to heat the melted metal (8) in the melting pot (4) until the molten metal (8) assumes a predetermined state and, a third predetermined time after that, operates a melting pot driver (9) to cause the molten metal (8) to be poured into the die (6).
