A method of three-dimensionally microcutting a metal material suitable for molds is provided. An electrolyte is interposed between a work piece which is made of a conductive material, and an electrode. Through application of an electrolysis voltage between the work piece and the electrode with the electrolyte interposed between them, a passive state film is formed on the surface of a to-be-cut part of the work piece. Then, the passive state film on the surface of the to-be-cut part of the work piece is cut.

An inverter circuit is connected in series to an AC power supply, and at the subsequent stage, a smoothing capacitor is connected via a converter circuit including semiconductor switching devices. A control circuit controls the converter circuit by providing a short-circuit period for bypassing the smoothing capacitor in each cycle, and controls the inverter circuit to improve the power factor of the AC power supply by using a current instruction such that the voltage of the smoothing capacitor becomes a target voltage. When the voltage of a DC voltage source of the inverter circuit has exceeded a predetermined upper limit, the control circuit increases the current instruction to control the inverter circuit, thereby increasing the discharge amount of the DC voltage source. Thus, even if the voltage variation of the DC voltage source of the inverter circuit increases, it is possible to stably continue the control.

A power conversion apparatus includes a high-power-factor converter section converting an AC voltage to a DC voltage, a smoothing capacitor, a DC/DC converter section, and a control circuit. The control circuit controls the high-power-factor converter section such that the power factor of AC is controlled and a DC voltage follows a target value, and performs duty control for semiconductor switching devices such that a DC voltage from the DC/DC converter section to a load follows an instruction value. In accordance with the DC voltage, the control circuit adjusts the DC voltage target value of the high-power-factor converter section such that the duty ratio of the semiconductor switching devices approaches a set value, thereby optimizing the duty ratio of the semiconductor switching devices and reducing power loss.

A lubricant composition for a resin conveyor, comprising specific (A) a nonionic surfactant and (B) water and, if necessary, (C) (a) a cationic surfactant and/or (b) an amphoteric surfactant, and a method for using same. Using a specific nonionic surfactant as the main component provides excellent washing ability, lubricating ability, and stability in storage. In particular, because excellent ability to prevent stress cracking is attained, the lubricant composition for a resin conveyor can be advantageously employed for transporting PET containers. Furthermore, adding a specific cationic surfactant makes it possible to obtain a lubricant composition for a resin conveyor also demonstrating an effect of inhibiting microorganism (fungi) generation, without degrading the various original performances (effects). Furthermore, a preferred method for using those lubricant compositions for resin conveyors is also provided.
