The accessory panel is mounted at a concave surface of the front cover when it is folded and at this time, the lamp and the PDA device are aligned with the windows of the front cover. When the accessory board is rotated through 180 degrees from the concave surface of the front cover, it forms an extending front cover panel. According to another structure, the accessory board is slidably mounted in the hollow front cover. Therefore, the user is able to use the PDA device while reading and writing with illumination and sound by playing the PDA device.

Abstract: A method of binding a sheet stack having a mounting hole includes the steps of: slidably inserting two fastening arms into the mounting hole of the sheet stack at a top side thereof until a first binding portion of a binding body is biased against the top side of the sheet stack at an edge portion thereof; adjustably bending a second binding portion of the binding body to bias against a bottom side of the sheet stack at the edge portion thereof with respect to a thickness of the sheet stack; aligning an elongated guiding slot of the binding body with the mounting slot; and bending the fastening arms for resting on the bottom side of the sheet stack to reinforce the edge portion of the sheet stack being securely sandwiched between the first and second binding portions of the binding body.

Abstract: A game controller includes a control unit and a control housing. The control unit includes a circuit board and a plurality of functional controls, wherein each of the functional controls has a movable control end and a signal end operatively coupling with the circuit board. The control housing includes an outer casing having a receiving cavity receiving the circuit board therein and a plurality of control holes for the control ends of the functional controls extending out of the receiving cavity, and an internal enclosure, which is received in the receiving cavity of the outer casing, having a sealing cavity for the circuit board supporting therein to form a double-wall structure to protect the circuit board and a plurality of guiding slots aligned with the control holes of the outer casing respectively to guide the functional controls extending to the control holes through the guiding slots respectively.

Abstract: A sports ball includes an inflatable bladder, and a ball carcass. The ball pocket is constructed to have a true roundness shape, having an interior cavity receiving the inflatable bladder therein, wherein when the inflatable bladder is inflated, the ball pocket retains a true roundness shape of the inflatable bladder. The ball carcass includes a ball cushion and a plurality of carcass panels. Each of the carcass panels has a peripheral edge and a flat bottom surface defined within the peripheral edge, wherein the bottom surface of each of the carcass panels is entirely affixed to the ball cushion at a position that the peripheral edge of each of the carcass panels is fittingly aligned with the peripheral edges of the adjacent carcass panels to form a roundness carcass of the sportsball in a stitch-less manner.

Abstract: A pillow cover includes a pillow casing and a neck support provided thereon. A neck support includes an elongated retention pocket and a neck supporting element received in the retention pocket therewithin. The user is able to use his or her own pillow to incorporate with the pillow cover such that when the user sleeps in a bed by using his or her own pillow for head support in a comfortable way, the neck support of the pillow cover provides a substantial neck support to keep the neck of the user in alignment with the spine while sleeping.

Abstract: A toilet seat includes a toilet bowl and a toilet platform. A toilet platform includes a bowl seat having a seating portion and a mounting portion. A seat hinge mechanism includes two spaced apart retention bases adapted for securely mounting at the toilet platform of the toilet bowl wherein the joint members are detachably engaged with the retention bases respectively for detachably mounting bowl seat on the toilet platform of the toilet bowl in a tool-less manner.

Abstract: A kind of fluorescent lamp driver power consists of a multi-switch converting circuit, a power transformer, a resonant inductor, a resonant capacitor, a step-up transformer and a rectifier. The primary winding of the power transformer connects with an AC output of multi-switch converting circuit. The resonant inductor and the resonant capacitor are connect to the secondary winding of the power transformer through the primary winding of the step-up transformer. The secondary winding of the power transformer connects with the rectifier. The secondary winding of the step-up transformer connects with the load output. This invention combines the fluorescent lamp driver power and the power supply of the control system, so that energy transformation occurs only once for the output from the Power Factor Correction Circuit to lamp.

Abstract: Provided is a protective concrete for weaken the intensity of proton radiation, and it is prepared by mixing 525# cement 500-700 Kg; barite sand 1000-1400 kg, barite stone 1500-1800 Kg, lead powder 180-200 Kg and water 170-180 Kg. The barite that can absorb the proton radiation is used, so the present concrete is much better than conventional concretes in weakening the proton radiation, and 1.5 m-thick wall without lead plates which is prepared with the present concrete can achieve the same effect on weakening the proton radiation with a conventional 2 m-thick wall covering with lead plates.

Abstract: A locker of a spectacle frame, adapted for connecting a first member and a second member of the spectacle frame, includes a receiving portion, an inserting portion and a locking mechanism. The receiving portion is adapted for providing at an end of the first member of the spectacle frame. The inserting portion, which is adapted for providing at an end of the second member of the spectacle frame, is arranged to be freely slide into the receiving portion. The locking mechanism includes a locking member movably disposed between the receiving portion and the inserting portion as a locking position to lock up the inserting portion from being detached from the receiving portion. The locking member is able to be driven from the locking position to an unlocking position that the inserting portion is able to be slid out of the receiving portion for separating the first and second members. The locker can be used in spectacle frame for exchanging and adjusting temples, end-pieces, hinges as well as the bridge.

Abstract: An oil gas separation membrane combines a gas permeable yet oil and temperature resistant bulk polymer membrane such as poly(tetrafluoroethylene) and poly(tetrafluoroethylene-co-hexafluoropropylene); a porous metal support such as sintered metal frit disk made with stainless steel, bronze or nickel; and an highly gas permeable adhesive that bonds firmly the bulk polymer membrane and the metal frit surface together. The adhesive is either a homogenous polymer that has desirable gas permeability, or a coalescent porous polymer particulates network. A gas sensor employing the oil gas separation membrane for detecting and monitoring fault gases of oil filled electrical equipment requires no mechanical wearing or moving part such as pump and valve and the gas sensor is operated normally under various temperature and pressure conditions.
