20080232979 | Compressor - A swash plate compressor ( | 09-25-2008 |
20080236979 | Power transmission apparatus - A power transmission apparatus comprising a pulley | 10-02-2008 |
20080305905 | Hub for power transmission apparatus - A hub for use in a power transmission apparatus comprises cylindrical portion | 12-11-2008 |
20090258741 | Power transmission device - A power transmission device includes a pulley | 10-15-2009 |
20100018827 | Drive force transmission apparatus - An armature is magnetically attracted to and is coupled with a rotor against an urging force of a resilient member by a magnetic attractive force of the rotor when a permanent magnet is placed into a first position. When the armature is coupled with the rotor, a rotational drive force of an internal combustion engine transmitted to the rotor is transmitted to a refrigerant compressor connected to the armature to rotate the refrigerant compressor. The armature is urged away from and is decoupled from the rotor by the urging force of the resilient member when the permanent magnet is placed into a second position. | 01-28-2010 |
20100259121 | POWER TRANSMISSION DEVICE - A power transmission device for transmitting a driving force from a vehicle-mounted driving source to a vehicle-mounted rotary device includes a driving rotor mechanically coupled to the vehicle-mounted driving source via a belt, and a driven rotor disposed coaxially with the driving rotor and mechanically coupled to a drive shaft of the vehicle-mounted rotary device. Furthermore, the power transmission device is provided with a magnetic join portion disposed in at least one of the driving rotor and the driven rotor, and the magnetic join portion is adapted to transmit a rotary driving force from the driving rotor to the driven rotor by a magnetic force, while keeping a predetermined clearance between the driving rotor and the driven rotor. Thus, in the power transmission device, a natural frequency can be made much lower than a frequency of vibration generated from the vehicle-mounted rotary device in idling of a vehicle. | 10-14-2010 |
20110083935 | CLUTCH MECHANISM AND CLUTCH SYSTEM HAVING THE SAME - When a pulley and an armature are coupled with each other, first and second permanent magnets place the movable member at a location where a magnetic resistance of an attracting magnetic circuit, which generates an attracting magnetic force to couple between the pulley and the armature, is reduced. In contrast, when the pulley and the armature are decoupled from each other, the movable member is placed at a location where the magnetic resistance of the attracting magnetic circuit is increased, and a magnetic resistance of a non-attracting magnetic circuit is reduced. Thereby, a coupled state or a decoupled state of the pulley and the armature can be maintained without an erroneous operation. | 04-14-2011 |
