Abstract:
A decolorization treatment method in which not only can a liquid that has been obtained by treating raw water that is stock-raising treatment water in a purifier tank be decolorized swiftly with simple equipment, but moreover the treatment water can be purified to an extent that reuse as a washing liquid or the like is possible. The method of decolorizing stock-raising treatment water comprises adding ferric polysulfate and a nonionic or anionic organic coagulant to a filtrate that has been obtained by treating raw water that is stock-raising treatment water in a purifier tank, and agitating the obtained product to bring about reaction and thus separate into solid and liquid components, and removing the solid component. Preferably, a two-stage reaction is carried out in which the ferric polysulfate is added and agitation is carried out to bring about reaction, and then the nonionic or anionic organic coagulant is added thereafter.

Abstract:
A method for controlling an internal supply voltage generating circuit reduces power consumption in an active mode. The internal supply voltage generating circuit includes a first voltage-drop regulator, which supplies a relatively large driving power to an internal circuit, and a second voltage-drop regulator, which supplies a relatively small driving power to the internal circuit. First, the second voltage-drop regulator is activated and the first voltage-drop regulator is inactivated in one of a stand-by mode and a power-down mode. Then, at least the first voltage-drop regulator is activated in an active mode, and the first voltage-drop regulator is inactivated in an active pause of the active mode. The first voltage-drop regulator is activated when the active pause is cancelled.

There is disclosed a multilayer insulated wire which comprises a conductor and solderable extrusion-insulating layers made up of two or more layers for covering the conductor, wherein at least one insulating layer is formed by a mixture comprising 100 parts by weight of a resin (A), of at least one selected from the group consisting of polyetherimide resins and polyethersulfone resins, 10 parts by weight or more of a resin (B), of at least one selected from the group consisting of polycarbonate resins, polyarylate resins, polyester resins, and polyamide resin, and 15 to 200 parts by weight of an inorganic filler (C). There is also disclosed a transformer which utilizes the multilayer insulted wire. The multilayer insulated wire is excellent in heat resistance, solderability, high-frequency characteristic, and coilability, and it is favorably suitable for industrial production. Further, the transformer utilizing the multilayer insulated wire is excellent in electrical properties and high in reliability, since when used at high frequencies, electric properties are not lowered and influence by the generation of heat can be prevented.
