| 20080210026 | Kinetic Energy Generation Device - A kinetic energy generation device comprises a case having a fixation gear wheel disposed at an interior rim thereof and engaged with a movable gear wheel. A motion transmission member is installed in the case, and a motion transmission shaft is provided at the axis of the motion transmission member. An axis gear wheel is disposed in relation to the movable gear wheel so that the axis gear heel is engaged with the motion transmission shaft. External to the axis gear wheel, a flywheel is engaged therewith and revolved in synchronization with the movable gear wheel. A force applying shaft is provided at an end of the flywheel. Each of several links Is connected to the force applying shaft with its one end and to a cylinder piston with the other end thereof. | 09-04-2008 |
| 20120073393 | ELECTRIC LINEAR-MOTION ACTUATOR AND ELECTRIC BRAKE ASSEMBLY - An actuator has planetary rollers disposed between a rotor shaft of an electric motor and an outer ring member fixed around the rotor shaft. The planetary rollers are rotated about the axis of the rotor shaft and about their own axes, thereby converting rotary motion of the rotor shaft to linear motion of the planetary rollers A helical groove is formed in the radially outer surface of each planetary roller in which a helical rib formed on the radially inner surface of the outer ring member is received. The helical groove has a pitch equal to that of the helical rib and a lead angle different from that of the helical rib. The amount of the linear motion of the planetary rollers relative to the amount of the rotary motion of the rotor shaft is determined by the difference in lead angle between the helical groove and the helical rib. | 03-29-2012 |
| 20120279331 | RING DISK RECIPROCATING POWER CONVERSION DEVICE - A ring disk reciprocating power conversion device includes a planetary gear set and at least one off-center control panel set. The off-center control panel set includes a rotary disk pivoted on the opposite end of the planetary gear set, which can be guided by the self rotation of the plurality of planet wheels of the planetary, forcing the rotary disk to do a reciprocating movement in limited amplitude. The periphery of the rotary disk forms annular chambers at intervals. The annular chambers accommodate a medium pressure forming medium. More than one variable volume chambers are formed at intervals in the annular chambers, and the periphery of the rotary disk is provided with equal amount of spacers as the variable volume chambers. The spacers can compress or draw the medium and further regulate and stop the self rotation of the planet wheel. | 11-08-2012 |
| 20130014602 | METHOD AND APPARATUS TO CONVERT LINEAR AND ROTARY MOTION TO ROTATIONAL TORQUE - Two separate motion converter apparatuses and methods using gears acting as levers to convert respectively reciprocal linear and circular motion as input to produce a higher torque rotational output. | 01-17-2013 |
| 20130025384 | VALVE ACTUATION MECHANISM - An improvement to a mechanism for actuating valves or other control mechanisms, either manually or by means of an electric/electronic, pneumatic or hydraulic actuator, rendering the mechanism independent and dispensing with specific controls. The redundant actuation mechanism comprises a reduction gear ( | 01-31-2013 |
| 20130333495 | LENS DRIVE UNIT AND IMAGING APPARATUS - A lens drive unit includes: a driven member that moves a lens in an optical axis direction; a first gear rotated by a drive force of a drive motor; a second gear rotated by a drive force of a manual operation section; a third gear that engages with the first gear and the second gear and is rotated when the first gear is rotated but the second gear is not rotated whereas rotated when the second gear is rotated but the first gear is not rotated; and a fourth gear rotated when the third gear is rotated to transmit the drive force of the drive motor or the drive force of the manual operation section to the driven member, wherein the reduction ratio of the fourth gear to the first gear is set to be greater than the reduction ratio of the fourth gear to the second gear. | 12-19-2013 |
