摘要:
A power saving circuit is to save standby power of electronic devices. A capacitor (1) is connected to an AC power supply (6), and a phase-leading current component passing the capacitor is used to make a DC power supply (10), as a power supply when in standby. In case an infrared command is used, the capacitor is connected in parallel to another capacitor (3) to strengthen the current output capability of the DC power supply, having an AC switching element (4) maintained in on state.

A process produces a resin intake member by injection moling. The intake member has a hollow generally cylindrical main section and a subsidiary section integrally connected to an outer periphery of the hollow main section. The process includes a primary molding step which forms the hollow main section in a primary molding die and a secondary molding step which subsequently inserts the formed hollow main section into a secondary molding die to integrally form the subsidiary section with the hollow main section in the secondary molding die.

The present invention relates to a substrate plating apparatus for plating a substrate in a plating bath containing plating solution. An insoluble anode is disposed in the plating bath opposite the substrate. The substrate plating apparatus comprises a circulating vessel or dummy vessel provided separate from the plating bath, with a soluble anode and a cathode disposed in the circulating vessel or dummy vessel. An anion exchange film or selective cation exchange film is disposed between the anode and cathode and isolates the same, wherein metal ions are generated in the circulating vessel or dummy vessel by flowing current between the soluble anode and the cathode therein, and the generated metal ions are supplied to the plating bath. The substrate plating apparatus can also comprise an ion exchange film or neutral porous diaphragm disposed between the substrate and anode in the plating bath, wherein the ion exchange film or neutral porous diaphragm divides the plating bath into a substrate region and an anode region.

A substrate plating apparatus forms an interconnection layer on an interconnection region composed of a fine groove and/or a fine hole defined in a substrate. The substrate plating apparatus includes a plating unit for forming a plated layer on a surface of the substrate including the interconnection region, a chemical mechanical polishing unit for chemically mechanically polishing the substrate to remove the plated layer from the surface of the substrate leaving a portion of the plated layer in the interconnection region, a cleaning unit for cleaning the substrate after the plated layer is formed or the substrate is chemically mechanically polished, a drying unit for drying the substrate after the substrate is cleaned, and a substrate transfer unit for transferring the substrate to and from each of the first plating unit, the first chemical mechanical polishing unit, the cleaning unit, and the drying unit. The first plating unit, the first chemical mechanical polishing unit, the cleaning unit, the drying unit, and the substrate transfer unit are combined into a unitary arrangement.
