Abstract: A switch device includes a P-type substrate, a first gate structure, a first N-well, a shallow trench isolation structure, a first P-well, a second gate structure, a first N-type doped region, a second P-well, and a second N-type doped region. The first N-well is formed in the P-type substrate and partly under the first gate structure. The shallow trench isolation structure is formed in the first N-well and under the first gate structure. The first P-well is formed in the P-type substrate and under the first gate structure. The first N-type doped region is formed in the P-type substrate and between the first gate structure and the second gate structure. The second P-well is formed in the P-type substrate and under the second gate structure. The second N-type doped region is formed in the second P-well and partly under the second gate structure.

Abstract: A faucet which includes a casing having a transverse partition wall and a valve chamber above the partition wall, the partition wall having a through hole for hot water and a through hole for cold water, a water outlet pipe having a spot, a valve mounted in the valve chamber and controlled by a handle to close/open the passage between the valve chamber and the spout, and a shower head adapter and control valve assembly mounted in the water outlet pipe and controlled to close the spout for permitting water to flow from the valve chamber to a shower head, a flexible hot water pipe and a flexible cold water pipe respectively connected to the through hole for hot water and the through hole for cold water by a respective rigid pipe connector, wherein the partition wall of the casing is spaced above the lowest edge of the casing at a distance longer than the length of the rigid pipe connectors of the hot water pipe and cold water pipe; the shower head adapter and control valve assembly has a swivel shower head conn

Abstract: An adjustable shower head holder including a mounting block mounted around the hanging rod of a wall mounting rack, a shower head mount coupled to the mounting block by a locating ring and a socket and a pivot to hold a shower head, and an adjustment knob coupled to the mounting block, and a holding down bolt controlled by the adjustment knob to hold the mounting block and the hanging rod together, wherein the holding down bolt can be released from the hanging rod by turning the adjustment knob relative to the mounting block, permitting the shower head to be adjusted in the X-axis and Y-axis directions; the shower head mount can be tunred relative to the mounting block to adjust the position of the shower head in the Y-axis direction.

Abstract: A wall mounting support includes a shell fastened to a wall by an anchor and a screw, the shell comprising a front guard spaced from a front wall thereof with a receiving chamber defined therebetween for receiving the object to be supported. The front wall includes two resilient corrugated locating plates bilaterally obliquely disposed in an elongated opening of the front wall with a narrow sliding hole defined therebetween for permitting the screw head of the screw to be located at different symmetrical pairs of depressions on the corrugated locating plates.

Abstract: A towel support comprising a wall plate mounted onto a wall surface by anchors and screws, a connector to connect a hanging device to a toothed stem on said wall plate, wherein said connector has an axial hole into which said stem is inserted, a bolt hole vertically in communication with said axial hole, and a screw rod movably fastened in the gap between either two teeth on said stem to firmly secure said connector to said stem and prohibit it from rotary motion.

Abstract: A towel support, which includes a wall plate having a projecting stem and elongated mounting holes for easy alignment of flat head screws with anchors which are secured inside a wall, to fasten the wall plate onto the wall, and a connector to secure hanging device to the mounting plate for holding towels. The connector comprises an axial hole into which the stem of the wall plate is inserted, a bolt hole vertically in communication with the axial hole, and a screw rod movably fastening in the bolt hole pressing against the top taper end of the stem to firmly secure the connector thereto.
