  • Publication number: 20140354860
    Abstract: A blur correction apparatus includes a first fixing member, a moveable member and a second fixing member. A coil for generating a magnetic flux is arranged on the first fixing member. The movable member includes (1) a first magnet facing the coil, (2) a second magnet arranged adjacent to the first magnet, such that the first magnet is arranged between the second magnet and the coil arranged in the first fixing member, and (3) an optical element. The movable member can move in a direction perpendicular to an optical axis of the optical element relative to the first fixing member. The second fixing member includes a hall element that is arranged adjacent to the second magnet in the movable member.

  • Patent number: 7841854
    Abstract: A temperature adjustment mechanism for use in an injection molding machine that shortens a molding cycle time while preventing the occurrence of a stranding phenomenon in an optimum manner. A passage includes an opening arranged near an outer surface of an outlet of an injection nozzle for an injection molding machine. A supply control unit supplies the passage with at least one of cooling air and heating air to selectively eject the cooling medium, the heating medium, and a mixture of the cooling medium and the heating medium near the outer surface of the outlet.

  • Patent number: 7577345
    Abstract: A digital camera having an acoustic member includes a first cover, a water-proof sheet and a second cover. The second cover is spaced from the water-proof sheet. The first cover has a first sound hole opposed to the acoustic member. The water-proof sheet is disposed such as to covers the first sound hole. The second cover has a second sound hole. The second sound hole is deviated in position toward an outer periphery of the first sound hole so that the second sound hole is not located on an extension of an axis of the first sound hole.
