  • Publication number: 20140037940
    Abstract: A cover film including, at least, (A) a substrate layer, (B) an intermediate layer, (C) a release layer and (D) a heat seal layer is provided. The release layer (C) includes a resin composition which includes (a) a styrene-based resin composition and (b) an ethylene-?-olefin random copolymer, with the content of the copolymer (b) in the release layer being 20 to 50 mass %, and which has a Vicat softening temperature of 55 to 80° C., while the heat seal layer (D) includes an acrylic resin having a glass transition temperature of 55 to 80° C. By the cover film, a carrier tape of polystyrene or the like can be so heat-sealed even in a short time as to achieve sufficient peel strength. Further, the resulting heat-sealed carrier tape exhibits little variation in peel strength, so that when peeling, few components fly out of the carrier tape.

  • Patent number: 7874503
    Abstract: An electrostatically atomizing device capable of instantly giving an electrostatically atomizing effect without requiring a water tank. The electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, a water feeder configured to give water on the emitter electrode, and a high voltage source configured to apply a high voltage across said emitter electrode and said opposed electrode to electrostatically charge the water on the emitter electrode for spraying charged minute water particles from a discharge end of the emitter electrode. The water feeder is configured to condense the water on the emitter electrode from within the surrounding air, enabling to supply the water on the emitter electrode in a short time without relying upon an additional water tank. Thus, an atomization of the charged minute water particles can be obtained immediately upon use of the device.

  • Patent number: 7803081
    Abstract: In system and method of controlling an automatic transmission that includes a lowest gear-stage friction element and has a lowest gear stage having a largest gear ratio and a gear stage other than the lowest gear stage, the lowest gear stage being established through engagement of the lowest gear-stage friction element, the gear stage other than the lowest gear stage being established while the lowest gear-stage friction element is kept in disengagement, a temperature of working oil in the automatic transmission is sensed, and use of the lowest gear stage is inhibited and use of the gear stage other than the lowest gear stage is allowed when the sensed temperature of the working oil is lower than a first predetermined temperature as a predetermined extremely low temperature at which an engagement failure of the lowest gear-stage friction element is caused.

  • Patent number: 7567420
    Abstract: An electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, and a cooling means which condenses the water on the emitter electrode from within the surrounding air, and a high voltage source applying a high voltage across the emitter electrode and the opposed electrode to electrostatically charge the water for atomizing charged minute water particles from a discharge end of the emitter electrode. The device further includes a controller for discharging the charged minute water particles in a stable manner. The controller monitors a discharge current flowing between the two electrodes to control the cooling means for keeping the discharge current at a predetermined level, thereby regulating the atomizing amount of the charged minute particles from the emitter electrode.

  • Patent number: 6419558
    Abstract: A polishing apparatus has a guide (5) to be pressed against a polishing cloth (7) when polishing an object (1). Within the guide, a ring (3) is arranged between a backing plate (4) and a backing film (2). When the guide and polishing cloth are rotated to rub with each other, force of the periphery of the object of pressing the polishing cloth drops. The ring prevents such a force drop, thereby equalizing polishing rates over a surface of the object. Also provided is a polishing method applied to the polishing apparatus.
