Abstract: A modulized bicycle frame includes at least two frame body members each sidelong symmetric to each other and having a head connecting portion, a seat connecting portion and a bottom-bracket connecting portion, and a plurality of fastening members for combining the frame body members to form the bicycle frame. The frame body members are easy to assemble and disassemble so as to facilitate replacement and modification of the modulized bicycle frame. Besides, the frame body members are suitable for mass manufacture, thereby saving manufacturing costs.

Abstract: A light-duty vehicle with an adjustable wheelbase includes a linkage assembly composed of at least one main rod, a movable support, at least one movable rod and at least one adjusting rod, at least one power source connected in the linkage assembly, a seat mounted on a connecting rod having one end pivotally connected to the movable rod, and a driving wheel set composed of at least one front wheel and at least one rear wheel. The rear wheel is rotatably connected to the adjusting rod, while an opposite end of the main rod is connected to a fixed rod, which is coupled to a front fork above the front wheel. Thereby, when the power source modifies the linkage assembly in posture, the wheelbase between the front wheel and the rear wheel is changed so that the seat is adjusted in posture and altitude.

Abstract: A wind-guidance enhancing apparatus for a wind power generator includes a support stage; an impeller stage including at least one blade, and a wind-guidance unit for guiding wind to the impeller stage. The wind-guidance unit includes a plurality of wind-guidance plates having wind-guidance faces, wind-guidance gates, and wind-guidance runners defined between adjacent wind-guidance faces and being shrunk toward the impeller stage. The wind-guidance gate is designed to be movable to adjust the width and flowing direction of outlets of the wind-guidance runners. Moreover, the wind-guidance enhancing apparatus further includes at least one gutter plate and the wind-guidance plates are arranged corresponding to a reference plate to enhance wind capturing angle.

Abstract: A windmill generator includes a wind-driven unit, a generating unit, and a wind-guiding device. The wind-driven unit includes a blade device with a plurality of blades and a shaft securely extending through the blade device to turn therewith. The generating unit is connected to the shaft. The wind-guiding device includes a rotary member rotatably mounted to the shaft, two wind plates respectively and securely mounted on two ends of the rotary member to turn therewith, and a wind-guiding housing rotatably mounted to the shaft. The wind-guiding housing guides the wind to a direction for driving an associated one of the blades of the wind-driven unit.

Abstract: A clamping apparatus of an injection molding machine includes a servo motor installed at the center of the rear platen and two timing belts to drive two ball screws so as to push a five point inwardly bending toggle mechanism to open the mold, close the mold and mold clamping. Moreover, a servo motor is fixed to the lateral side of the movable platen to drive the nuts of the screw to rotate so as to push the ball screw, ejector rod and ejector plate to move linearly for achieving the object of ejecting. An electromotive motor on the rear platen will drive the mold adjusting means. By the assisting of the servo motor on the rear platen, the function and object of automatic mold adjusting can be achieved rapidly.

Abstract: A hollow screw cooling device, which has a set of apertures provided on an oil-proof base on the driven end of the hollow screw. By having fixing screws go through the apertures and the through holes on the bearing press board and fixed on the bearing base, the oil-proof base can be fixed on the outer side of the bearing press board. By directly taking off fixing screws, the oil-proof base can be directly taken off the bearing base when maintaining or replacing the seal without disassembling the components such as the bearing and bearing device.

Abstract: A tool holder of the hollow taper shank in a tool machine is disclosed. A resisting block supported by a spring is received within a tool holder. As the short knife is disposed within the tool holder, the elastic force of the spring can be overcome. At first, a plurality of steel balls and a resisting block are pushed inversely until the front edge of an wider portion of the short knife passes through the steel ball. Now, the spring will release the energy from elastic deformation so as to enforce the resisting block to move forwards and outwards so as to return to the original position. Thereby, the knife can be firmly secured.

Abstract: A sliding unit includes a load-receiving device for permitting a load to be received thereon, a guiding device slidably mounting thereon the load-receiving device for permitting a direct relative sliding motion therebetween, and a load-sharing device mounted between the load-receiving device and the guiding device and capable of being in a rolling motion therebetween for resulting in a rolling contact effect therebetween. Such sliding unit can meet the demand of a high positioning precision/a high movement stability/a smaller friction coefficient/a better rigidity/a better vibration-resistivity.
