A vacuum breaker includes a safe valve body and an elastic gasket. The safe valve body has a receiving space which has a periphery provided with connecting holes. The elastic gasket has a size smaller than that of the receiving space, with clearances being defined between the elastic gasket and the receiving space. The elastic gasket has a center provided with a through hole and has an outer periphery provided with a sealing portion. Thus, the sealing portion contracts inward when water stops passing the safe valve body, so that ambient air flows into the receiving space to break a vacuum state in the safe valve body, such that a fluid contained in the safe valve body flows through the clearances between the elastic gasket and the safe valve body, and is drained outward from the connecting holes.

A semiconductor device including a first wafer assembly having a first substrate and a first oxide layer over the first substrate. The semiconductor device further includes a second wafer assembly having a second substrate and a second oxide layer over the second substrate. The first oxide layer and the second oxide layer are bonded together by van der Waals bonds or covalent bonds. A method of bonding a first wafer assembly and a second wafer assembly including forming a first oxide layer over a first substrate. The method further includes forming a second oxide layer over a second wafer assembly. The method further includes forming van der Waals bonds or covalent bonds between the first oxide layer and the second oxide layer.

A headset includes two sound output units and a connector connecting the two sound output units. Each of the two sound output units includes a limiting part arranged thereon. The connector is made of an elastic material and capable of being flexibly mounted to each of the limiting parts so as to improve the convenience of using the headset by making it easy to wear, adjust and collect.

A vacuum breaker includes a main body, a bushing, an elastic member, a braking member, a water stop gasket, a water inlet disk and a washer. The interior of the main body is provided with a positioning groove. The bushing is made of metallic material and has an exterior provided with a positioning protrusion secured in and combined integrally with the positioning groove of the main body. The bushing is extruded outward by an oil pressure to form the positioning protrusion. Thus, the bushing is combined with the main body integrally and will not be detached from the main body.

An exterior pressure detection device for detecting fluid pressure in pipes includes a body in which a circuit board and a pressure detection unit are received. The pressure detection unit includes a board and a pressure detecting chip which is electrically connected to the circuit board. An L-shaped clamping bar has a connection section and a clamping section which is parallel to the board. A pipe is clamped between the board and the clamping section. When the volume of the fluid passing through the pipe and changes the diameter of the pipe, the board is moved to activate the pressure detecting chip which transfer the change of the diameter of the pipe into a signal which is sent to the exterior main controlling device via the signal output device of the circuit board.

The invention relates to a computer system capable of automatically duplicating data into discs with automatically blank-disc-supplying. The invention can be implemented by software, hardware, or any of the combinations. Since the invention does not utilize a mechanical arm to move the discs, the structure of the invention saves space compared with a traditional disc duplicating machine; moreover, the cost is less than that of the prior art.
