摘要： Disclosed is a novel fluorocarbon comprising carbon atoms and fluorine atoms and having no double bond, the atomic ratio of fluorine to carbon atoms being 1.50 to 1.93, which exhibits a liquid state at room temperature. The liquid fluorocarbon has excellent water- and oil-repellent properties and can advantageously be used, for example, not only as a water- and oil-repellent but also as an inert liquid, a heat transfer agent and a vapor phase soldering liquid in various fields, especially in the electronic industry. The liquid fluorocarbon can be obtained directly from a pitch or from a pitch fluoride which can be obtained by direct fluorination of a pitch.

摘要： A voltage detection section and current detection section detect a voltage and current supplied to a motor, and the detected voltage and current are supplied to a position detection section. An angular speed output from the position detection section is supplied to a differentiator to output an angular acceleration. A fundamental wave component extraction section extracts a fundamental wave component of the angular acceleration, and the extracted fundamental wave component is supplied to an amplitude adjustment section. The output of the amplitude adjustment section is subtracted from the average current command by a subtraction section. This subtraction result, current detection value, and the rotor position from the position detection section are supplied to a current control section to carry out the current control operation so as to obtain a current command. The current command is supplied to an inverter to control the voltage and current so as to suppress the speed changing due to the load torque changing. Thus, stability is improved, and a decrease in cost is realized.

摘要： A power converter circuit includes a diode group, a relay, a DC section and an inverter. The diode group includes a plurality of diodes arranged to rectify an output voltage of an alternating-current power supply. The relay is provided at a point located closer to the alternating-current power supply than the diode group. The DC section is where an output voltage of the diode group is applied. The inverter is arranged to output a three-phase alternating-electric current to a three-phase load. The DC section has a maximum pulse voltage twice as great as a minimum pulse voltage of the DC section. The DC section includes an energy-absorbing circuit having an electrolytic capacitor. The DC section further has a pathway arranged to apply the output voltage of the alternating-current power supply from the alternating-current power supply to the electrolytic capacitor via a rectifying circuit, not via the relay.
