Abstract: An angle-adjustable device between two tubes used as a play place for pets comprises a first connecting unit connected to a first tube, a linking body connected to the first connecting unit, and a second connecting unit connected to a second tube and the linking body. By such arrangements, a pipe is formed as a play place for the pets, and the shape of the pipe is adjustable.

Abstract: A power supply apparatus includes a power source; and at least a capacitor module formed by connecting a plurality of capacitors in series, having an input connector connected to a municipal power source supply or connected to a cigarette-lighter receptacle of a car for inputting direct current for quickly charging the capacitors of the capacitor module, and having an output connector connectable to a portable electric device including cellular phone and other portable devices each having rechargeable battery provided therein for quickly charging the portable electric device for keeping its continuous operation.

Abstract: A substantially rectangular or square sunshade formed of a static adhesive material is releasably mounted on an automobile's window. The sunshade includes an elongated guide member along a lower edge thereof. The guide member is formed of relatively hard plastics. The guide member is concealed in a lengthwise groove in an intermediate portion of the automobiles doorframe when the window is closed. A predetermined gap is formed between the guide member and an adjacent intermediate edge of the doorframe so as to permit free passing of the guide member either through the lengthwise groove into an interior cavity of the doorframe or out of the interior cavity prior to being concealed in the lengthwise groove.

Abstract: A foldable shade having a four-sided shape comprises an elongated, magnetic base having a section of U, a plurality of parallel slats wherein each of the odd numbered slats includes a plurality of longitudinal grooves adjacent either side, and two pairs of a plurality of projections, each pair being disposed between the grooves and the side, and each of the even numbered slats includes a plurality of longitudinal projections adjacent either side, and two pairs of a plurality of grooves, each pair being disposed between the projections and the side; and a plurality of suction cups fixedly provided at the slat farthest from the base. The slat next to the base is inserted therein. In a folded state the grooves of each of the remaining slats are inserted in the projections of the immediate next slat proximate the base.

Abstract: An automatic power-generating device for decorative lamps has a weight-distributing plate or a heavy weight inside. Rotation of an exterior object produces an eccentric force (a centrifugal force) to rotate the weight-distributing plate or the heavy weight together with a coil and a magnet. The coil and the magnet rotate at different speeds due to the law of inertia to force magnetic field produced vicissitudes and to generate an inductive current (based on a principle of electromagnetic induction) to supply decorative lamps with power for lighting. Thus, the automatic power-generating device is able to save electricity and is convenient to be installed.
