    摘要: There is provided a guide device for a machining head capable of machining a workpiece such as a cylinder head of an engine accurately, a machine having the guide device, and a guide method. At least one of guide posts formed in a guide post member has an air pressure controlling function capable of fitting and holding a guide bar in the guide post in a non-contact state, and other guide bars have a very small clearance with the guide post facing to the guide bar. Thereby, the position at which the machining head is held is accurately held.

    摘要: A control apparatus for controlling motors of an air conditioner comprises a converter circuit having switching circuitry for converting AC power to DC power and setting an input voltage of an input alternating current waveform to a sine wave of the same phase as that of an input voltage, first and second brushless motors for driving a compressor and a blower, first and second inverter circuits for converting the converted DC power to AC power and supplying AC power to the first and second brushless motors, and a microcomputer for controlling the compressor and the blower of the air conditioner. The microcomputer is constructed in such a manner that input and output operations which are necessary to control the air conditioner are executed for input and output circuits, thereby controlling at least the compressor and the blower of the air conditioner. To improve the input power factor from the AC power, a PWM signal for controlling the ON/OFF state of the switching circuitry of the converter circuit is generated by the microcomputer on the basis of the input alternating current of the AC power and the output DC voltage of the converter circuit. At the same time, PWM signals for controlling the ON/OFF state of switching circuitry of the inverter circuits are generated by the microcomputer to control the first and second motors.

    摘要: A control apparatus for controlling a motor of an air conditioner includes a converter, having switching for improving an input power factor, for converting an AC power to a DC power and an inverter for converting the DC power supplied from the converter to the AC power and supplying to a compressor. The output DC voltage of the converter is detected by a DC voltage detecting circuit. An input alternating current is detected by a current detecting circuit. A microcomputer for controlling the inverter calculates a current command from data stored on the basis of the detected voltage. The detected current is compared with the current command, an ON percentage of a PWM signal to control the switching is obtained, and the PWM signal is generated.
