Abstract: A lamp includes a tube, a reflector, at least one illuminator unit, at least one radiator and two connectors. The tube is made of a transparent material. A reflector is disposed in the tube. The illuminator unit includes at least one light-emitting diode for emitting light. The radiator includes a first reduced portion inserted in the tube, a second reduced portion located opposite to the first reduced portion and fins for dissipating heat generated by the light-emitting diode. The first reduced portion of the radiator is formed with a face for supporting the illuminator unit so that the light-emitting diode can cast the light to the reflector that can reflect the light. The connectors are connected to the illuminator unit for conducting electricity to the illuminator unit from a power supply.

Abstract: A method for producing high-active titanium dioxide anatase hydrosol by using metatitanate as precursor, is characterized in comprising the following steps in order: (1) Wash process: adding alkali to wash so as to remove sulfate ion; (2) Dispersion process: adding acid to disperse the filter cake and obtaining a uniform suspension; (3) Peptization process: peptizing the suspension obtained in dispersion process according to the method of (a), (b) or (c). When producing transition metal or rare earth doped anatase hydrosol, transition metal or rare earth salt solution with a predetermined concentration is first prepared, and then added into the metatitanate suspension which has not been washed by alkali. Subsequently, the resulting suspension is filtered and washed until no sulfate ion is present. When producing precious metal deposited anatase hydrosol, precious metal solution is added into prepared pure anatase hydrosol, and then, the resulting solution is irradiated with ultraviolet light for 0.

Abstract: A circuit board carrier has main frame, at least one first holder, at least one slide and at least one second holder. The first and second holders are mounted on and selectively slide on the main frame. The slide is mounted on and selectively slides on the corresponding first holder. The slide has a first pin and the second holder has a second pin. The circuit board is held on the circuit board carrier by the pins. Therefore, the circuit board is kept from being contacted to the delivering wheels during manufacturing and is not polluted and trapped by the delivering wheels.

Abstract: A treadmill includes a drive roller disposed in a tread base, a treadmill belt engaged with the drive roller, and a wheel attached to the drive roller and rotated in concert with the drive roller, and an electric generating device is attached to the tread base and includes a fan device attached to a spindle, and the spindle is engaged with the wheel for allowing the spindle of the electric generating device to be driven and rotated by the wheel and the drive roller and the treadmill belt in order to generate the electric energy, and the fan device is also to be driven and rotated by the wheel and the drive roller and the treadmill belt without the other electric energy, in order to generate the circulating or ventilating air to cool the user.

Abstract: A planter includes a plant growing container having a chamber formed by an outer peripheral wall, a number of posts erectly disposed on the outer peripheral wall, an upper cover disposed on top of the posts and having a number of channels, and a number of door panels slidably engaged through the channels of the upper cover and engageable between the posts covering or shielding the plant growing container and for preventing diseases and insect pests from entering into the plant growing container. The door panels and the partitions and the posts may be engaged into the container for forming a compact folding structure and for storing and transportation purposes.

Abstract: An adjustable barbell or dumbbell or exercise device includes a handle, two carriers each having a tubular member attached to the end portion of the handle and each having a number of slots, a number of weight members attachable onto the tubular member of the carrier, and two latch members each having a shank engaged into the tubular member and each having a number of latch tongues extendible out through the slots of the carrier for engaging with the weight members and for anchoring the weight members on the carrier and the handle, and the latch tongues are selectively engageable into the tubular member of the carrier for allowing the weight members to be attached to and disengaged from the carrier and the end portion of the handle.

Abstract: A rest for cleaning a rifle and for sighting a scope, a stock, and a bore of the rifle. The rest includes a base, a vise assembly, a fore-end support assembly, and an elevator assembly. The vise assembly adjusts for different-length rifles and clamps the stock of the rifle therein. The fore-end support assembly adjusts for the different-length rifles and supports the fore-end of the rifle thereon. The elevator assembly adjusts for the different-length rifles and supports the barrel of the rifle therein. The rest further includes a lapping tool, alignment tools, a stock alignment tool, a bore sighting tool, a centering tool, and a set of diopters. The lapping tool insures smoothness and proper interior profile of the mounting rings for a scope. The alignment tools insures that the scope fits properly without any binding or protrusions. The stock alignment tool lines up the stock of the gun so the gun is leveled. The bore sighting calibrates the scope. The centering tool cradles, centers, and supports the gun.

Abstract: A kettlebell includes a kettle member having a pivotal coupling member, and a handle having another pivotal coupling member pivotally engaged with the pivotal coupling member of the kettle member, and the kettle member and the handle include guide members engaged with each other for limiting and guiding the kettle member to rotate relative to the handle along a longitudinal axis of the handle and for preventing the kettle member from pivoting and rotating relative to the handle along the lateral axis of the handle, and for preventing the user from being twisted or hit or hammered or hurt by the kettle member of the kettlebell inadvertently.
