摘要:
A flush valve structure to control flush water through a pressure difference mainly includes a case, a solenoid assembly, an upper intermediate board, a lower intermediate board and a main water ball. The upper intermediate board has a small water pressure release hole. The lower intermediate board has a holding trough mating a medium water valve. The solenoid assembly can open the small water pressure release hole to generate a pressure difference to actuate the medium water valve to form a greater pressure difference so that the main water ball is lifted rapidly to fully open the a main water discharge opening to flush maximum amount of water in a shortest period at the flushing start time.

The present invention discloses a driving structure for a power generator along a coastal land using kinetic energy of wave. The power generator is operated via upward and downward swing of a toggle lever. The structure is provided with a wave-guiding channel for constraining flow direction of waves. The channel is provided with two side walls, an end portion connecting the side walls, and an intake opening toward the ocean, so as to form a gully. At the top of side wall, an extending portion is provided near the end portion. The extending portion is provided with a pivot. The structure is further provided with a floating body in the gully near the end portion. The floating body is provided at one end thereof with a coupling portion connected to the pivot, and provided at the other end thereof with an abutting portion abutted against the toggle level.

A manual and automatic flow control valve includes a valve body, a manual control unit, a hollow pressure-releasing device, a middle plate, an upper casing, and an electric controlled magnetic unit. The internal of the valve body has a water inlet chamber and a water outlet chamber. A plastic main water flow valve is formed therebetween for isolating the two pressure chambers. A hollow pressure-releasing device is installed in a hollow portion of a main water flow valve. An upper side of the main water flow valve is a middle plate which is installed with an upper pressure chamber. The manual control unit can push the hollow pressure-releasing device to tilt. The electric controlled magnetic unit can control the hollow pressure-releasing device to communicate with the upper pressure chamber. If water drains from the lower pressure chamber, the water will push away the main water flow valve.

A hand dryer with annular air exhaust includes a casing and an air supply device located in the casing. The casing has a coupling portion and an air exhaust portion connected to the coupling portion. The air exhaust portion has two extension sections extended from the coupling portion and a connection section connected to the two extension sections to form an annular hand drying passage. The air exhaust portion includes a plurality of first nozzles and a plurality of second nozzles corresponding to the hand drying passage which has a first opening and a second opening at two ends. The air supply device has an airflow guiding duct to direct air to the air exhaust portion. The first and second nozzles exhaust the air towards the hand drying passage to form annular air exhaust, and thus hand drying angles are increased to dry hands faster.

A method for manufacturing casings of composite hand dryers and the structure thereof includes the processes of severing a reproduced steel rough material to form a front casing, bending the front casing, fabricating a first side casing and a second side casing that have respectively a coupling portion, assembling one end of the front casing with the first side casing and assembling another end of the front casing with the second side casing to form a finished composite hand dryer casing. The method and structure can eliminate rusting and product strength problems. Fabrication process is simplified and production cost is lower.
摘要:
A device includes a semiconductor substrate having a front side and a backside. A photo-sensitive device is disposed on the front side of the semiconductor substrate. A dielectric layer is disposed on the backside of the semiconductor substrate, wherein the dielectric layer is over a back surface of the semiconductor substrate. A metal shield is over the dielectric layer and overlapping the photo-sensitive device. A metal plug penetrates through the dielectric layer, wherein the metal plug electrically couples the metal shield to the semiconductor substrate.
