摘要:
A tent having two joints, multiple frames and a fly. The frames are mounted on the joints and are classified into a stationary frame, a supporting frame and at least one pivoting frame. The frames cooperate to define a parking space for receiving a cycle when unfolding. The fly covers the frames and the parking space. The frames are capable of folding and overlapping one another to facilitate carrying and storage of the tent.

A master jaw assembly used in a vise including a locking jaw, a detachable jaw and a clamping device disposed in the locking jaw, securely clamping the detachable jaw to the locking jaw. The locking jaw has a groove extending along an inner surface of the locking jaw defined by a first and second edge. The second edge is tapered inward and downward toward the base. The detachable jaw has a dovetail protrusion along one side surface thereof. The clamping device includes a plurality of specially-shaped clamp-nuts having a downwardly tapered edge, said clamp-nuts designed to receive one end of a double-ended threaded stud. The detachable jaw becomes fixed to the locking jaw by inserting the protrusion into the groove and torquing the studs to tighten the clamp-nuts downward against the protrusion such that the protrusion is clamped between the taper of the second edge and the clamp-nuts.

A sprinkler has a sprinkling device, and an inlet controlling device and an end cap respectively mounted on two opposite ends of the sprinkling device. The sprinkling device has a casing having outlet holes, and two regulating panels having regulating slots, two regulating wheels, two transmission rods and a cover having limit slots mounted on the casing. The outlet holes, the regulating slots and the limit slots respectively align with each other and are mounted around multiple nozzles. Turning the regulating wheels forces the nozzles to bend through the regulating panels so the sprinkler has a variety of sprinkling patterns to be suitable for every place where the sprinkler is placed. The nozzles are individually manufactured and are easily mounted on the casing and replaced.

The present invention relates to a method for manufacturing a flat plate heat pipe, which includes steps of: forming a wick structure layer and at least one wick structure post on the inner surface of a chamber of a pipe, pressing the pipe to become a flattened pipe with the wick structure post being connected therein, connecting a conduit to the chamber, sealing both sides of the flattened pipe, evacuating air inside the chamber through the conduit, filling a working fluid into the chamber, and sealing the conduit. According to this method, a flat plate heat pipe can be made in a simplified manner with increased yield and reduced cost.

An auto-stop air pump has a housing, a blower and an auto-stop device. The housing has an upper chamber, a lower chamber, a main inlet and an outlet. The upper chamber and the lower chamber communicate with each other. The main inlet and the outlet are formed through the housing respectively and communicate with the upper chamber. The blower is mounted in the housing and has a motor connected to a dual-sided impeller. The auto-stop device is mounted in the housing and has a shell, a film, a micro switch and an actuating unit. The film and the micro switch are mounted in the shell. The actuating unit is mounted movably through the shell. Owing to deformation of the film by pressure, the film presses the micro switch to close the micro switch so the air pump can stop working automatically.

There is a method for enabling a SONOS transistor to be used as both a switch and a memory. FN tunneling is carried out through the source or drain of the transistor, so as to further change the state of electrons stored in an upper charge storage layer adjacent to the drain or source, and the variation in gate-induced drain leakage is used to recognize the memory state of the drain and source. A stable threshold voltage of the transistor is always maintained during this operation. The present invention enables one single transistor having dual features of switch and memory, while being provided with a two-bit memory effect, thus providing a higher memory density in comparison with a general transistor.

The present invention is a light emitting diode lamp structure, which comprises a heat dissipating plane, a light emitting housing and a base. The light emitting housing further comprises a casing and a first hollow region. The heat dissipating plane is partly covered by the casing and the rest of the heat dissipating plane is shown in the first hollow region. The part of the heat dissipating plane covered by the casing further includes a plurality of LEDs. The base is mounted with the light emitting housing and electrically engaged with the LEDs.
