Abstract: A laminated optical disk, applied for lighting system or solar energy system, includes a plurality of annular lenses, a base and a circular light guiding unit. The annular lenses are arranged in order from center to outside to form a disk-structure. Each annular lens has a light-input curved surface and a light-output curved surface respectively matching the different thickness of the base. The light-input curved surface is opposite to the center. The light-output curved surface is opposite to the light-input curved surface, and facing to the center. The light is incident on the light-input curved surface, refracted and tended to concentrate by the light-input curved surface. Besides, the light exiting from the annular lens is to be refracted to the direction of the center by the light-output curved surface. The base of the laminated optical disk can significantly improve the light leakage problem by different annular lenses.

Abstract: A magnetic sweeper includes a tubular body made of a non-magnetic material, a magnet unit, and a slider made of a non-magnetic material. The magnet unit is disposed inside the tubular body, and is capable of attracting and retaining magnetically attractable pieces on an attracting portion of the tubular body. The slider is mounted on and is slidable along the tubular body such that movement of the slider on the tubular body can result in pushing of the magnetically attractable pieces out of the magnetic range of the magnet unit such that the magnetically attractable pieces can fall freely from the tubular body.

Abstract: A tool-holding seat includes a seat body having a flat bottom face and a flat top face opposite to the flat bottom face. The seat body is formed with a plurality of parallel spaced apart bit-retention holes which extend inwardly from the flat top face. Each of the bit-retention holes is capable of retaining a workpiece-driving bit therein, and defines an axial line along the length thereof. The axial line of each of the bit-retention holes is inclined relative to the flat bottom face at an acute angle. A magnetic piece is embedded in the seat body adjacent to the flat bottom face.

Abstract: A magnetic sweeper includes an elongated mounting frame, a pair of rotating wheels, and a universal caster. The frame includes a barrier wall disposed behind a guide wall so as to define an axial hole therebetween, and a bottom plate. At least one magnetically attracting wheel is disposed in the axial hole, and is sleeved fixedly on a rotating shaft. The rotating wheels are rotatable relative to the frame to rotate the magnetically attracting wheel within the axial hole so as to magnetically attract metal objects onto the guide wall of the frame. Thereafter, the objects move from the guide wall to the barrier wall, and drop from the barrier wall to the bottom plate.

Abstract: A storage rack includes a casing having opposite front and rear walls, a bottom wall, and a partition plate interconnecting and cooperating with the front and rear walls to define a seat-receiving channel above the partition plate and with the bottom wall to define a retainer-receiving channel below the partition plate. The front wall has a lower section defining an elongated opening in spatial communication with the retainer-receiving channel. A tool-holding seat is removably disposed in the seat-receiving channel, and has a plurality of bit-retention holes extending inwardly from a flat top face thereof for holding tool pieces therein. A plurality of U-shaped retainers are mounted on the lower section of the front wall along the length of the elongated opening, and abut against one another so that each adjacent pair of the retainers can clamp a tool piece therebetween.
