    摘要: A motor driving apparatus includes a comparator, a threshold controller, a position determining unit, a phase-switching controller, and a current output unit. While the rotor is stopped, the phase-switching controller supplies a predetermined phase of winding with a current pulse having a predetermined pulse width so as not to cause the rotor to react and operate, in order to determine the initial position of the rotor. The position determining unit determines an initial position of the rotor based on the result of comparison between the induced voltage generated in a non-conduction phase by the current pulse and the threshold. The phase-switching controller performs energization or commutation according to the determined initial position of the rotor to start up the motor.

    摘要: A disk drive apparatus reproduces an information signal from a disk and/or records an information signal on the disk. FET power transistors of a power supplying part execute high-frequency switching operation and form current paths to three-phase windings so as to rotate the disk. A voltage detecting part compares terminal voltages of the three-phase windings and produces a detected pulse signal in response to a comparison result. An activation operation block controls active periods of the FET power transistors in response to the detected pulse signal. A commanding part produces a command signal in response to an output pulse signal of the voltage detecting part. A switching operation block produces a switching pulse signal in response to a comparison result of a current-detection signal with the command signal, and causes at least an FET power transistor of the power supplying part to perform high-frequency switching in response to the switching pulse signal. The switching operation block changes a timing of the switching pulse signal in response to detection of the detected pulse signal so that the voltage detecting part can accurately achieve the next detection of the detected pulse signal. Further, an excellent speed control of the disk can be achieved by the accurate output pulse signal of the voltage detecting part.

    摘要: A thermocouple temperature sensor employs a protecting tube made of metal-boride-based ceramics, and a platinum -rhodium-based thermocouple. To prevent a deterioration of the thermocouple due to a reducing gas generated in the protecting when used at a high service temperature, the thermocouple is placed in an insulation tube, which is placed inside the protecting tube. In addition, a front end portion of the insulation tube is covered with a noble-metal cap mainly composed of platinum group metal, to prevent the reducing gas generated in the protecting tube from reaching a connection point of the thermocouple. The top end of the protecting tube is open, and a terminal box with a ventilation means to smoothly discharge the reducing gas in provided. This arrangement remarkably prolongs the service life of the thermocouple, and thus it is able to continuously measure the temperature of molten pig iron and molten steel for a long interval.
