摘要:
A DC voltage resulting from rectifying and smoothing a commercial AC voltage is converted into a high-frequency voltage in an inverter which is operated in response to the closure of a start switch. A transformer transforms the high-frequency voltage, and the voltage-transformed high-frequency voltage is converted to a DC voltage by a rectifier and reactor for application between a torch and a workpiece with a gap disposed therebetween. In response to the closure of the start switch, an igniter operated from the voltage-transformed high-frequency voltage is enabled by an igniter driver to thereby apply a high-frequency voltage between the torch and the workpiece to generate an arc therebetween. A current detector detects current attributable to the arcing. A timer starts operating upon closure of the start switch and causes a disabling commander to disable the inverter when no current is detected by the current detector during a time period longer than a period required for an arc to be generated in the gap. This interrupts the supply of the operating voltage for the igniter, and the igniter stops operating.
摘要:
Power supply apparatus includes a converter which converts a commercial AC voltage into a DC voltage. An inverter converts the DC voltage into a high frequency voltage. The high frequency voltage is voltage-transformed by a transformer, and then rectified and smoothed by a rectifier and a smoothing reactor into a DC voltage. This DC voltage is applied between a workpiece and a torch. A high frequency voltage generator generates a high frequency voltage and applies it to a primary winding of a coupling transformer. A boosted high frequency voltage is induced in a first secondary winding and applied between the workpiece and the torch, so that arcing is initiated. The coupling transformer includes a second secondary winding in which another high frequency voltage is induced. The high frequency voltage induced in the second secondary winding is converted into a DC voltage by a diode and a smoothing capacitor for application between the workpiece and the torch, so that the arcing is sustained.

In an NPN bipolar transistor having a special structure in which each impurity region is formed by ion implantation, a width of a base region is significantly reduced, and therefore, current amplification factor hfe is increased, resulting in improvement in performance thereof. Furthermore, a Bi-CMOS transistor can be manufactured using a CMOS process. The use of the bipolar transistor having a special structure for a driving circuit allows implementation of a driving circuit having large driving force with slight increase in cost.

A power supply apparatus for arc-utilizing equipment includes a first converter for converting a received AC voltage to a DC voltage. An inverter converts the DC voltage to a high-frequency voltage, which is applied to a voltage-transformer with primary and second windings. A voltage-transformed high-frequency voltage induced in the secondary winding is converted to a DC voltage in a second converter, which is developed between two output terminals. The respective ones of the two output terminals are connected to a torch electrode of the arc-utilizing equipment and a workpiece. A bypass capacitor and a high-frequency voltage generator circuit are serially connected between the two output terminals. A control circuit controls the high-frequency voltage generator circuit and the inverter circuit. The bypass capacitor is connected directly between one of the two output terminals and the high-frequency voltage generator circuit.

A compound represented by formula (I) wherein the symbols in the formula are the same meanings as those in specification, salts thereof, solvates thereof, or prodrugs thereof binds to DP receptor and shows antagonistic activity for DP receptor. Thus, it is useful for prevention and/or treatment of diseases such as allergic disease (e.g., allergic rhinitis, allergic conjunctivitis, atopic dermatitis, bronchial asthma and food allergy), systemic mastocytosis, disorders accompanied by systemic mast cell activation, anaphylaxis shock, bronchoconstriction, urticaria, eczema, diseases accompanied by itch (e.g., atopic dermatitis and urticaria), diseases (e.g., cataract, retinal detachment, inflammation, infection and sleeping disorders) which is generated secondarily as a result of behavior accompanied by itch (e.g., scratching and beating), inflammation, chronic obstructive pulmonary diseases, ischemic reperfusion injury, cerebrovascular accident, chronic rheumatoid arthritis, pleurisy, ulcerative colitis, etc. Since it specifically binds to DP receptor and binds weakly to other prostaglandins receptors, they can be pharmaceuticals having little side effect.
