  • Publication number: 20120246744
    Abstract: A license server (400) controls each user terminal (100) on the basis of a license permitting a user terminal (100) to reproduce any content and permitting another user terminal (100) to reproduce a content identical to a content that is being reproduced by the above user terminal (100). A service use status change detecting section (411) detects that the user terminal (100) that is permitted to reproduce any content has switched its reproducing content. A license authorization control section (412), in the case where such a switch has been detected, switches a content, which the other user terminal (100) is permitted to reproduce, to a content being reproduced by the user terminal (100) that is permitted to reproduce any content.

  • Publication number: 20120144942
    Abstract: A transmission that is able to perform shift operation and select operation using the driving force of a single electric motor is provided. A shift/select actuating device includes: an electric motor; a first conversion mechanism; a second conversion mechanism; and a changing unit that changes a destination, to which the rotational driving force of the electric motor is transmitted, between the first conversion mechanism and the second conversion mechanism. The changing unit includes: a first electromagnetic clutch that transmits the rotational driving force of the electric motor to the first conversion mechanism or interrupts the rotational driving force; and a second electromagnetic clutch that transmits the rotational driving force to the second conversion mechanism or interrupts the rotational driving force.

  • Publication number: 20110194954
    Abstract: An electric pump unit includes: a unit housing; a bearing unit provided within the unit housing; a rotary portion; and a motor stator fixed to the unit housing. The rotary portion includes: a pump driving motor shaft supported by the bearing unit such that an axial position of a center of gravity of the rotary portion falls within an axial range of the bearing unit, and a motor rotor. The motor rotor includes: a disc portion which extends radially outwards from an axial end portion of the motor shaft; and a cylindrical portion which extends from an outer circumferential portion of the disc portion towards the other axial end side and surrounds an outer circumference of the bearing unit.

  • Publication number: 20110095714
    Abstract: Provided is an electric pump device that can continue to supply hydraulic pressure to hydraulically actuated equipment and that is also of reduced size. An electric pump device is provided with an oil pump that supplies oil to a stepless transmission device, a brushless motor that drives the oil pump, and a control device that controls the brushless motor. The control device is provided with a power supply part that supplies drive power to the brushless motor, and an out-of-synch determination part that determines whether or not the brushless motor is out of synch. The control device is provided with a drive control part that controls the power supply part so that supply of power to the brushless motor is stopped, and then controls the power supply part so that the brushless motor is started, when the out-of-synch determination part determines that the brushless motor is out of synch.

  • Patent number: 5955545
    Abstract: A coating for polyolefin molding compositions comprises (1) (a) from 40-90% by weight of a chlorinated polyolefin grafted with a vinyl-polymerizable monomer having a hydroxyl group at a position 15 to 40 atoms distant from the main chain of vinyl polymer grafted onto the chlorinated polyolefin, or (b) from 50 to 90% by weight of a vinyl polymer obtained by polymerizing from 5 to 40% by weight of a hydroxyl group-containing (meth)acrylate monomer having a carbon chain derived from an alcohol residue with from 6 to 18 carbon atoms, and a vinyl-polymerizable monomer having a hydroxyl group at a position 15 to 40 atoms distant from the vinyl group, wherein the vinyl polymerizable monomer is derived from the reaction product of a vinyl-polymerizable monomer having a hydroxyl group at a position 2 to 12 atoms distant from the vinyl group and a lactone, and (2) from 10 to 60 or 50% by weight of a melamine resin containing methylol, alkoxy or imino groups.
