Abstract: The present invention provides an eccentric roundel structure for three-compressing-chamber diaphragm pump. The eccentric roundel structure is a truncated-cylinder eccentric roundel in an eccentric roundel mount. The truncated-cylinder eccentric roundel characteristically comprises an annular positioning dent, a truncated cylinder peripheral and a sloped top ring created from the annular positioning dent to the truncated cylinder peripheral to replace a conventional rounded shoulder. By means of the sloped top ring, the oblique pull and squeezing phenomena of high frequency incurred by the rounded shoulder in a conventional tubular eccentric roundel are completely eliminated. Thus, not only the durability of the three-compressing-chamber diaphragm pump for sustaining the pumping action of high frequency from the truncated-cylinder eccentric roundels is mainly enhanced but also the service lifespan of the three-compressing-chamber diaphragm pump is exceedingly prolonged.

Abstract: The present invention provides a thermal energy exchanger for bathing shower water comprising an upper deck, a lower chassis and two hatches. The upper deck features creased top surface, multiple parallel septa and plural heat conducting ribs being created between each pair of adjacent septa. After having assembled, the circulation of internal water tunnel is configured into a continual zigzag duct to increase energy saving effect in consequence of improvement in heat exchanging efficiency of the water heater. With simple structure, it is easily fabricated by traditional extruding method without welding process and related welding technician. Thereby, selling price is reduced with marketing competitiveness because overall manufacturing cost is decreased so that the purchasing intention of the consumers is spurred. Thus, it is not only favorable to promote and penetrate marketing range and depth but also valuable to achieve energy saving and carbon reducing effect.

Abstract: A keyboard switch includes a top cover, a pressing part, a spring, a bottom base, a fixed contact and a moving contact. The moving contact is provided with a first contact surface and two second contact surfaces of arched shape at two sides of the first contact surface. The fixed contact is provided with a third contact surface with at least two protruding portions formed thereon; the fixed contact is in contact with the first contact surface through the protruding portions. The pressing part is provided with an inclined surface corresponding to the second contact surfaces; when the pressing part is pressed to move downwardly, the inclined surface acts on the second contact surfaces and pushes the moving contact away from the fixed contact to cause the protruding portions to separate from the first contact surface.

Abstract: It is possible to shorten channel monitoring periods of unoccupied channels during Wi-Fi discovery by verifying whether or not a message indicating the presence of a Wi-Fi AP has been detected prior to the probe timer reaching a medium channel time (MedChannelTime). For example, STAs detecting some channel activity during the clear channel assessment may nevertheless discontinue monitoring a Wi-Fi Channel when no messages indicating the presence of a Wi-Fi AP are detected prior to expiration of the MedChannelTime. Messages indicating the presence of a Wi-Fi AP may include any Wi-Fi messages sent from or destined for a Wi-Fi AP, while excluding probe requests and non-Wi-Fi messages.

Abstract: The present invention provides a five-compressing-chamber diaphragm pump with multiple effects, which comprises an eccentric roundel mount with five cylindrical eccentric roundels, a pump head body with five operating holes, and a diaphragm membrane with five annular positioning protrusions. A basic curved dent is circum-disposed around each operating hole while a basic curved protrusion is circum-disposed around each corresponding annular positioning protrusion for suitably coupling upon assembly. A short length of moment arm from the basic curved protrusions to the annular positioning protrusion is obtained. By the pump head body and diaphragm membrane, the present invention solves harassing noise and vibrating resonant shakes in the conventional five-compressing-chamber diaphragm pump. The cylindrical eccentric roundel comprises a sloped top ring created from an annular positioning dent to a vertical flank in the eccentric roundel mount.
