Abstract: A bearing-lubricating structure for a direct drive torque motor comprises a body, a direct drive torque motor, a main shaft, a bearing assembly, an adjustment nut and an oil-filling assembly. The bearing assembly includes an assistant roller bearing which is positioned against the rear cover, the main shaft and the adjustment nut. The rear cover is defined with a lubrication oil piping, which is communicated to the assistant roller bearing and communicated to an annular lubrication space located between the rear cover and the adjustment nut. The oil-filing assembly is mounted on an open end of the lubrication oil piping. Thereby, with the abovementioned simplified structure, the main shaft can be lubricated, and the maintenance cost can be reduced.

Abstract: An adjustable handlebar assembly for a stand comprises a handlebar and a positioning assembly. The handlebar is rotatably mounted on the stand, and the positioning assembly serves to position the handlebar. The handlebar can be rotated to adjust its operation angle and can be positioned by the positioning assembly after rotating to a desired angle, so that the user can adjust the operation angle of the handlebar according to his own stature and habit, thus enhancing the convenience of use.

Abstract: A connecting device for an actuator comprises two actuators, a connecting assembly and a motor. Mandrels of the actuators are located correspondingly to each other, and lower ends of the actuators are connected to each other. A connecting assembly is provided for connecting the mandrels of the actuators, such that the actuators are combined with each other. A motor serves to drive the mandrel of one of the actuators, enabling the actuators to extend or retract simultaneously. Thereby, one motor can drive two actuators simultaneously, thus obtaining a double travel length by using only a single actuator, so the structure is simple and the cost is low, and the connecting device for an actuator is easy to assemble.

Abstract: A clearance eliminating structure for a shaft of a direct drive torque motor comprises: a body, a direct drive torque motor, a bearing assembly and an adjustment nut. The main shaft includes a plurality of stages which are used to positioning the torque motor and the bearing assembly, and then torque motor and the bearing assembly are used to position the body. The main shaft is formed at the end with threads for enabling the adjustment nut to press tightly against the respective components on the main shaft. When the present invention is used on the assembly of the direct drive torque motor, which can not only simplify the assembly operation, improve the reliability, but also eliminate the clearance of the main shaft to increase the service life of the product.

Abstract: A support with detachable footrests comprises a body and two footrests. The two footrests are detachably assembled on the body. When the support is stored, the two footrests can be detached from the body, and then inserted into both sides of the body, thus greatly reducing the storage space.

Abstract: The concept of the present invention can be applied to a transmission system which is comprising a power device, a driving link and a driven system wherein the driving link is operatively connected to the power device and for transmitting the motive power generated by the power device to the driven system. A lubricant-infusing device according to the present invention comprises at least one lubricant-infusing point provided on the driving link at a location adjacent to the power device wherethrough a lubricant can be infused to offer lubricant and cooling functions to the mechanism of the driven system.

Abstract: A torque controlling device for being equipped around a motor shaft and providing warning to an operator of idle running of the motor and allowing the operator to adjust for proper torque control thereby at least comprises a ball settled on the surface of the motor shaft, a through passage radially passing through the worm shaft accommodating said ball, an elastic element arranged upon the ball and a screw provided upon the elastic element.

Abstract: A time-division method for playing multi-channel voice signals is provided to improve voice qualities of the multi-channel voice signals. The first feature of the present invention is that after time-division sampling, the voice signals can be directly sent to a subsequent voice generator without being demodulated beforehand. The second feature is that the ratio of a specific voice signal to a synthesized voice can be easily adjusted by changing the numbers of channels occupied by the specific voice. Consequently, the adjusting circuitry can be significantly simplified.

Abstract: A rubber eraser and method of fabrication is disclosed. The mixture comprising a rubber eraser composition comprising non-crosslinked polymer, plasticizer, stabilizer, thixotropic filler and pigment; wherein the non-crosslinked polymer is a basic material ranges from 20% to 40% by weight; the plasticizer ranges from 30% to 50% by weight; the stabilizer ranges about from 2% to 5% by weight; the thixotropic filler ranges about from 20% to 40% by weight for the rubber eraser mixture to form into a soft clay-like mixture; and pigment ranges from about 0.5% to 1% for coloration of the eraser. The method includes the steps of heating the eraser mixture for at room to 50-70 degree C.; mixing the mixtures and kneading cutting or pressing to form into a desired shape; and placing the obtained product into an oven or hot air device at temperature 120° C. to 130° C.

Abstract: A joystick control device having cursor correcting function, in which the conventional adjustable resistor is replaced by a photoelectric element for detecting the movement of the joystick, thereby eliminates the ill effects caused by mechanical attrition of resistor. Additionally, the parameter drifts caused by IC manufacturing processes are corrected using shift correction of joystick; therefore, every individual mass-produced IC shows similar good behavior.
