Abstract: The present invention discloses an endodontic sealer which comprises a urethane-acrylate oligomer, a diluting monomer, at least one photo-initiator, at least one thermal-initiator, and a filler, wherein the urethane-acrylate oligomer is obtained by firstly reacting the acrylate with the diisocyanate to form an intermediate with only one isocyanate group, and then reacting the intermediate with the polyol to form the desired urethane-acrylate oligomer.

Abstract: The present invention discloses a Polyurethane (PU) composite material comprising a thermoplastic polyurethane and a filler. The thermoplastic polyurethane comprises a linear polyurethane main-chain, and the polyurethane main-chain comprises a soft segment and a hard segment. The hard segment of the polyurethane main-chain is formed by a diisocyanate and a chain extender, and the soft segment of the polyurethane main-chain is formed by a polyol. The present invention also teaches the application of the disclosed thermoplastic polyurethane composite material in dental root canal material.

Abstract: A laptop computer supporting device for use both on desktop and on user's lap, comprising a back plate detachably attached to the computer's bottom, a set of arms pivotally connected to said back plate and a long board, whereby said long board rises variably away from the computer; a set of control components, functioning in conjunction with a controlling means consisted in said back plate, for adjusting the extent to which said long board rises such that the tilting angle of the computer's keyboard can be selected. Said back plate provides plural holes to receive fasteners, such as snap fasteners, which are to be bonded to the computer's bottom; alternatively, removable adhesive products can be used instead of such fastener; in either case, the device according to this invention is detachable from the computer when desired. Said long board has a width to provide comfort when resting on user's lap.

Abstract: A communication card has a bottom panel, a top cover and a top panel, which is able to accommodate an electronic device. The electronic device has a circuit board and a RF transceiver coupling to the circuit board. The circuit board further comprises at least a metallic ground layer extending along the whole area of the circuit board, such that the dissipation of EMI from the backside of the circuit board can be prevented. The bottom panel and the top panel are both made of an electromagnetic wave penetrable material, and the top cover is made of an electromagnetic wave impenetrable material. The connecting means that can inter-engage with each other are respectively applied on the bottom panel and the top cover, and between the bottom panel and the top panel. After assembling, the circuit board is substantially positioned between the top cover and the bottom panel, and the RF transceiver is substantially positioned between the top panel and the bottom panel.

Abstract: A platform for securely mounting a wafer cassette holder thereon is provided which includes a wafer cassette holder that has a flat bottom surface and four sidewall panels, a platform that has a flat top surface larger than and for mating to the flat bottom surface of the wafer cassette holder, and a securing means mounted in the flat top surface of the platform juxtaposed to each side of the four sidewalls of the wafer cassette holder for preventing the holder from accidentally slipping off the platform. The securing means may include either a plurality of engagement pins that slidingly engages the wafer cassette holder for securely holding the holder on the platform, or a plurality of side panels mounted along the peripheral edge of the platform for preventing the holder from slipping off the platform.

Abstract: A balanced dipole antenna for a mobile phone comprises a radiator element and a counterpoise, both formed of a conducting material. The counterpoise is electrically isolated from the ground plane of a printed wire board (PWB) of the mobile phone. A matching network, for example, a balun, provides balanced current to the dipole antenna, resulting in a symmetric radiation pattern. The balanced dipole antenna allows superior performance over conventional antennas found in mobile phones today by enabling a user of a mobile phone to communicate effectively and uniformly in all directions, that is, 360 degrees.

Abstract: A cradle can be mounted in a vehicle, or other suitable location, for supporting a wireless dual-frequency telephone that includes an antenna. The cradle includes a plastic housing and a ground plane disposed in the housing. A trough-shaped feed coupler element is electrically connected to matching circuits and an input/output connector. A first parasitic coupler element is aligned with the feed coupler element, and connected to the ground plane, and electromagnetically couples signals having a first frequency to and from the antenna. Together, the elements hold the antenna of the telephone. Also, a second parasitic element is disposed adjacent the feed coupler element for electromagnetically coupling signals to and from the antenna, that have a second frequency. If desired, the ground plane is established by a first conductive board and a second conductive board elevated above the first board.

Abstract: An apparatus for detecting defects in a wafer edge and a method for detecting are disclosed. In the apparatus, an ultrasonic detection unit is used to detect crazing or micro-cracks in a wafer edge, while a laser detection unit is used for detecting cracks in the wafer edge. The ultrasonic detection unit and the laser detection unit may be positioned in a detection module together with a wafer platform for holding and rotating a wafer positioned thereon. The detection module is placed in a mini-environment of clean room conditions which also include a robot transport device and a wafer storage cassette. The present invention novel apparatus is compact in size and can be moved to any location in a fab plant such that it is positioned adjacent to a process machine.
