| 20120000418 | SPINDLE MOTOR TRAY ADHESIVE DISPENSING METHOD AND SUPPLEMENTARY APPARATUS - A spindle motor tray adhesive dispensing method and supplementary apparatus is disclosed. The apparatus includes a base block and a pressure block. The base block supports the tray to be processed, having a blind hole for receiving one end of the center axle of the tray and three adhesive troughs around the blind hole. The pressure block pressed on the tray above the base block and axially movable relative to the base block, having a guide hole for receiving the other end of the center axle of the tray. An open space is defined above the base block around the pressure block within which an adhesive dispenser is movable to dispense a polymer adhesive to the through holes on the tray and the adhesive troughs of the base block to form rubber pads at the tray when cured. | 01-05-2012 |
| 20110069949 | Camera shutter - A camera shutter comprising a shutter driving means which has permanent magnets on both ends of a swingably journaled swinging lever and drives a shutter blade by conduction of electricity to a magnet coil wound around an iron core that is fixed so as to face the permanent magnets, thereby performing efficient motion. A camera shutter comprises a base plate having a shutter opening; a shutter blade for opening and closing the shutter opening; and a driving means for driving the shutter blade, wherein the driving means comprises a swingably journaled swinging lever having arm portions on both sides of a rotating shaft as well as a portion connected to the shutter blade, permanent magnets provided on both ends of the arm portions, a magnet coil wound around an iron core that is fixed so as to face the permanent magnets of the both ends, and an electromagnetic drive circuit for controlling electricity conduction to the magnet coil; and the swinging lever is operated by attractive force toward or repelling force against the permanent magnet that is generated by conduction of electricity to the magnet coil to drive the shutter blade. | 03-24-2011 |
| 20110069948 | Camera shutter - A camera shutter comprising a shutter driving means which does not immediately start an operation to provide stable movement even though an operation signal is output. A camera shutter comprises a base plate having a shutter opening; a shutter blade for opening and closing the shutter opening; and a driving means for driving the shutter blade, wherein the driving means comprising a swingably journaled swinging lever having an arm portion connected to the shutter blade, a permanent magnet provided on the arm portion, restraining members comprising a magnetic material that face each other at least at one of both end positions of an operating range of the swinging lever and a magnet coil fixed so as to face the permanent magnet; the swinging lever is operated by attractive force toward or repelling force against the permanent magnet that is generated by conduction of electricity to the magnet coil to drive the shutter blade; and an operation of the swinging lever is restricted by the restraining member at an operation stop position and/or a fully open position of the shutter blade under the magnetic force of the permanent magnet. | 03-24-2011 |
| 20110038066 | VOICE COIL MOTOR TYPE FOCUSING ACTUATOR - A voice coil motor type focusing actuator is disclosed to have a fixed unit, a movable unit and two resilient holding members. The fixed unit has a bracket with two slide shafts and a plurality of magnets mounted in the bracket. The movable unit has a lens holder movably mounted inside the bracket and a coil wound around the lens holder. The lens holder has two lugs. Each lug has a through hole for the slide shaft of the fixed unit to insert thereinto. The resilient holding member is fastened between the bracket of the fixed unit and the lens holder of the movable unit. When a current is supplied to the coil, a magnetic force is produced between the coil and the magnets to move the movable unit. When the current stops, an elastic force due to the resilient holding unit is utilized to pull the movable unit back to its original position. | 02-17-2011 |
| 20090284100 | Motor that reduces magnetic interference - A motor includes a housing formed of a first shell and a second shell, a stator, which is formed of a first yoke, a second yoke, a connecting device and two coils. The first yoke and the second yoke each comprise a terminal holder mounting portion, a race and a plurality of pole pawls respectively extended from the race. The race of the first yoke has the race of the first yoke kept apart from the race of the second yoke at a distance to reduce magnetic interference, the connecting device having a terminal holder fastened to terminal holder mounting portions of the first yoke and second yoke of the stator and a plurality of metal terminals installed in the terminal holder, the coils respectively set between the first yoke and the first shell and between the second yoke and the second shell and respectively electrically connected to the metal terminals, and a rotor formed of a transmission shaft and magnets and inserted through the first yoke and the second yoke and rotatable relative to the stator. | 11-19-2009 |
| 20080231975 | Voice coil motor type focusing actuator - A voice coil motor type focusing actuator, which includes a fixed unit, the fixed unit comprises a receiving chamber, a slide fitting channel, a first coil, and a magnet. A movable unit, the movable unit is received inside the receiving chamber of the fixed unit, having a first magnetic conducting flange being affected by the first coil and magnet of the fixed unit, a lens receiving means, a slide fitting rail, the movable unit is movable relative to the fixed unit to define an axial line. | 09-25-2008 |
