Abstract: A rotary joint includes a shaft having a first end, a second end, and a cavity. The rotary joint includes a first waveguide section having a first proximal end and a first distal end. The first proximal end of the first waveguide section is positioned within the cavity and secured to the inner surface of the shaft. The rotary joint includes a second waveguide section that includes a second proximal end and a second distal end. The second proximal end of the second waveguide section is positioned within the cavity of the shaft and unsecured to the inner surface of the shaft to form a radial gap between an outer surface of the second proximal end and a laterally adjacent portion of the inner surface of the shaft. The shaft and the first waveguide section are configured to rotate about the rotational axis and relative to the second waveguide section.

Abstract: An inflatable furniture comprises: a receiving body, a plurality of side-board-connecting members, airbag-connecting members, a pump, a power supply, two airbags, and an audio device. By opening the side boards and inflating the airbags, the airbags can be inflated into beds or sofas, and when after use, the airbags can be deflated and folded into the receiving body. Furthermore, the receiving body can also be temporarily used as a tea table or a stool.

Abstract: An inflatable furniture comprises a packing unit and an air bag. The packing unit is a T-shaped unitary laminar body and includes a back portion, two first covering portions and a second covering portion, the first covering portions extend from both lateral sides of the back portion and the second covering portion extends from a middle of the back portion and is located between the two first covering portions, the second covering portion of the packing unit is provided around its periphery with first zipper teeth to be engaged with second zipper teeth which are formed around a periphery of the first covering portion and the back portion of the packing unit, so that the back portion, the first covering portion and the second covering portion are connected together to form the packing unit in the form of a luggage case.

Abstract: An inflatable sofa set comprises a receiving body, a pump and at least one airbag which is received in the receiving body. The airbag is connected to the pump. When in use, the user drives the pump to inflate the airbag into a sofa for the user to sit on, or to deflate the airbag for storage. Thereby, the sofa set is simple and is convenient for storage.

Abstract: A telecommunication connector includes a housing, a circuit board mounted in the housing and holding a set of communication terminals and a set of connection terminals, the connection terminals being obliquely aligned at the circuit board in a staggered manner, reducing cross-talk, a wire block mounted on the circuit board to a communication line in connection to the connection terminals, the wire block having a guide plate in the wire hole thereof and connected between two locating walls and sloping forwardly downwards form a guide space for guiding the bare wires of the communication line into respective terminal grooves at an equal distance to ensure stable communication quality, and two movable covers pivoted to the housing and adapted to hold down the wire block and to protect the circuit board and the connection terminals against external dust.

Abstract: An optical scanner for retrieving digital images of opaque and transmissive objects. The scanner of the present invention includes a scanner body, a docking port, and a removable scanning platform. An object to be scanned is placed on the scanning platform, which is subsequently loaded into scanner body for scanning. Inside the scanner body, a sensor module, including a first light source and an image-retrieving device, is disposed above the docked scanning platform; a support frame, on which is disposed a second light source, is disposed below the docked scanning platform. A connecting rod engages the sensor module and the support frame, and a driving device synchronously moves the sensor module and the support frame along a longitudinal axis. In a first embodiment, the scanning platform can include an adhesive tape for adhering an opaque object to be scanned to the surface of the scanning platform.

Abstract: A method of forming channel for metal oxidation semiconductor in the integrated circuits. The manufacturing process is as following: a layer of amorphous silicon is deposited after forming the gate oxide, and ion implantation for forming channel is performed, then a doped polysilicon layer and a silicide layer are deposited orderly, finally the whole structure is defined to form a gate electrode. The key point of the current invention is the addition of amorphous silicon. This amorphous silicon can prevent the direct bombardment of implanted ions to the gate oxide, it can also avoid the diffusion of polysilicon dopant into the gate oxide, therefore, the electrical properties of transistor will be made stable. In addition, the native oxide spontaneously produced between amorphous silicon and polysilicon along with process is very even and plain, it is profitable to planarization when subsequently depositing other layers.
