The electric actuator includes a fan unit provided with an impeller for forcibly suctioning the air in the space of the actuator body by a motor. The air suctioned by the fan unit is discharged from a discharge port at an end of the air guide.

Abstract: An electric actuator comprises an actuator body which is a rectangular cylinder having two pairs of opposing surfaces disposed in parallel and which has a slit formed to extend by a predetermined length along an edge of the rectangular cylinder; a slider which reciprocates along the slit of the actuator body by a rotary driving source; the rotary driving source which is connected to one end of the actuator body; and a driving force-transmitting mechanism which converts the rotary driving force of the rotary driving source into the rectilinear motion which is transmitted to the slider.

Abstract: A drive unit of a carriage has a drive wheel and a deflector, offset parallel to a racks both of which are implemented as gearwheels, around which a closed elastic toothed belt with teeth on both sides is guided, whose inner teeth engage with the wheels described and whose outer teeth engage with the rack. A pressure block relocatable relative to the rack is positioned between the wheels, which exercises an elastic force on the part of the toothed belt facing the rack by means of a pressure surface under the influence of the part facing away from the rack, which presses the first part mentioned against the rack. In this way, a snug engagement with the rack and low-noise and uniform movement of the carriage are always ensured. A pressure wheel implemented as a pinion and engaging with the inner teeth of the toothed belt can also be used instead of the pressure block.

Abstract: The present invention includes a first positioning assembly and a second positioning assembly respectively mounted on the bottom housing of the scanner. The first positioning assembly defines a first clamping groove, and the second positioning assembly defines a second clamping groove. A toothed belt is used to drive the chassis of the scanner to move reciprocally. The toothed belt includes a first end and a second end respectively locked in the first clamping groove of the first positioning assembly and the second clamping groove of the second positioning assembly. The toothed belt can be mounted directly, without having to additionally perform a working process, thereby reducing the machining processes, and thereby decreasing the cost of fabrication.

Abstract: A gear unit in which a cable, band or similar device is fitted between the drive and the output in order to transform a fast rotational movement at the drive end, which is limited in both directions, into a slow rotational movement at the output end. The cable is fastened at both ends to an oscillating intermediary single-piece divided into two segments, and rests against the outer walls of the intermediary piece and is wound around the shaft of the drive so as to transfer a driving torque. A position sensor is assigned to the inner segment of the intermediary piece, and/or a torque sensor is mounted between both segments of the intermediary piece. A fast rotational movement of the drive is transformed into a slow rotational movement without play, and provides a good synchronization characteristic.

Abstract: A double gear reduction drive mechanism for powering movement of a boat lifting cable for moving of a watercraft upwardly from the water to an elevated position and downwardly from the elevated position of storage to a position in the water therebelow. The device includes two gear reduction mechanisms within the same housing or within separate adjacent housings which can be connected to a drive means for powering rotational movement of a cable spool with at least one boat lift cable attached thereto. This gear drive is a direct drive system since it does not include any belts, chains or pulleys but utilizes direct engagement between two immediately adjacently positioned pairs of gears each of which reduces rotational speed to effect an increase in power, torque and accurate control of movement of boat lifting cable.

Abstract: A displacement device for realizing high-precision displacement, in particular for reduction projectors, includes a housing, a movable element which can move relative to the housing, and a moveable drum. The drum is enveloped by flexible elements, with first ends of the flexible elements fixedly attached to the housing and the respective other ends of the flexible elements attached to the movable element on the diametrically opposite side of the drum, whereby the flexible elements are pretensioned.

Abstract: To ensure that a laser beam is not disturbed during its transmission for the laser generator to a laser cutting head, the laser beam is conveyed along a beam guide enclosure. One side of the beam guide has an opening channel which is covered by a cover sheet that is slidably movable along substantially the length of the open channel. An aperture is formed on the cover sheet, and a conduit connects the aperture to the laser cutting head assembly. A reflective mirror is mounted relative to the conduit and is movable along the axis of the laser beam so as to intercept the laser beam and reflect it through the conduit to the laser cutting head assembly. The cover sheet is made of a flexible material that is impervious to either the laser beam itself or the heat generated by the laser beam. Rollers are provided at both ends of the cover sheet to from respective coils of the cover sheet so as to take up any slack.

Abstract: A walking-type snow removal machine comprises a snow removing member provided at a front part of a body frame for pushing snow forward, and crawler belts provided on right and left sides of the body frame. The body frame carries thereon an electric motor and a battery. The electric motor drives right and left drive wheels to drive the crawler belts. The electric motor generates little noise as compared with an engine, and contributes to downsizing of the snow removal machine. The battery supplies electrical power to the electric motor.

Abstract: Apparatus for generating rotating motion includes one or more electrical motors or generators arranged in a circle about a central shaft. The motors or generators are attached to a rotatable plate, which in turn is attached to the central shaft. The shafts of the motors or generators are belt connected to a fixed core. Operation of the motors results in rotation of the plate and the central shaft, which further results in the motors or generators orbiting around the central shaft.

Abstract: The invention relates to a gear unit in which a cable, band or similar (2) is fitted between the drive and the output in order to transform a fast rotational movement at the drive end, which is limited in both directions, into a slow rotational movement at the output end. The cable (2) is fastened at both ends (21, 22) to an oscillating intermediary single-piece (3) divided into two segments (31, 32). The cable rests against the outer walls of the intermediary (2) and is wound around the shaft (41) of the drive (4) so as to transfer a driving torque. A position sensor is assigned to the inner segment (31) of the intermediary piece (3), and a torque sensor (6) is mounted between both segments (31, 21) of the intermediary piece (3). In the inventive gear unit, a fast rotational movement of the drive is transformed into a slow rotational movement. This takes place without play and provides a good synchronization characteristic.

Abstract: A take-up pulley for a carrier in an image processor has a drum-like section with a boss-like projection extending from one end. In one embodiment, a recess is formed at the other end of the drum-like section for receiving a bearing. A stopper flange is formed at the end of the drum-like section adjacent the boss-like projection. The take-up pulley can be formed by a suitable molding process such as extrusion using the mold adapted to be opened axially. The take-up pulley is fixedly mounted on the driving shaft in the housing of an image processor so that a gap G smaller than a diameter of a drive wire may be formed between the end surface of the drum-like section and an inner wall of the housing. In another embodiment, an annular stopper plate is affixed to the end of the drum section instead of the recess.
