Abstract: An improved structure of linear actuator includes an actuator including a gear set having a friction portion located at the periphery of the gear shaft of a driven gear thereof, a one-way bearing mounted on the gear shaft for rubbing against the friction portion to brake the driven gear from reverse rotation, a driver for driving the gear set and a transmission mechanism including a lead screw coaxially coupled to and rotatable by the gear shaft of the driven gear and a retractable tube assembly coupled to the lead screw and movable by the lead screw between an extended position and a received position, and a stopping mechanism including a thrust bearing coupled to the gear shaft of the driven gear and stoppable against an inner race of the one-way bearing inner race to bear an axial thrust load.

Abstract: An electric actuator assembly comprises a main actuator including a gear set containing a stepped friction portion located on a gear shaft of a drive gear thereof, an extension rod, and a power drive for rotating the gear set to move the extension rod through a lead screw, and a one-way bearing consisting of an inner race fitted to the gear shaft of the drive gear, an outer race surrounding the inner race, and a backstop mechanism mounted in between. When operating the power drive to rotate the gear set in lifting the extension rod, the inner race is rotated by the gear set relative to the outer race in one direction. When the driving power is off, the one-way bearing cannot rotate in reverse direction, the stepped friction portion is abutted against the flat contact surface of the inner race to produce a braking effect, preventing falling of the load that is supported on the main actuator.

Abstract: Disclosed is a linear actuator structure in which a seat body of a linear actuator body has a receiving space inside and a gear set is disposed in the receiving space, and a driving part is mounted with the seat body for driving rotation of the gear set, and the gear set is linked with a transmission mechanism having a lead screw, an extending outer tube is mounted with the seat body and has channel formed inside for insertion of the lead screw, the extending outer tube has the sliding groove axially recessed on the outer surface thereof and in communication with the channel.

Abstract: The present invention discloses a method to deposit particles on a charge storage apparatus with charge patterns and a forming method for charge patterns. The forming method for charge patterns includes providing the charge storage apparatus having an electrically conducting substrate and a charge storage media layer. The charge storage apparatus is disposed in a vacuum or an anhydrous environment. An electrode and the electrically conducting substrate are utilized to conduct a first voltage and a second voltage respectively to form an electric field. Charges are then stored into the charge storage media layer of the charge storage apparatus through the electric field and the charge patterns are then formed. Accordingly, particles are deposited on the charge pattern-defined areas.

Abstract: A lifting motor drive includes a gearbox housing, a transmission shaft mounted inside the gearbox housing and having a first connector at one side for the connection of an external object to be moved by the transmission shaft and a second connector at the other side for the connection of a crank handle for allowing rotation of the transmission shaft manually by a user, a motor for rotating the transmission shaft through a driving gear and a driven gear, and a thermistor, which detects the working temperature of the motor and cuts off power supply from the motor when the working temperature of the motor surpasses a predetermined temperature level.
