Abstract: A flow guiding device in an immersion-cooled chassis of a server comprises at least one deflector located above a chip on a mainboard in the chassis, each deflector comprises a first end for mounting to the mainboard above the chip and a second end inclined away from the mainboard. The first end is immersed in coolant, the second end is higher than the first end; the deflector further comprises a hollow part including multiple through holes for interrupting upward movement vapor bubbles generated by the hot chip, which reduces probability of the vapor bubbles escaping from the coolant liquid and the chassis. A liquid-cooled chassis having the flow guiding device is also disclosed.

Abstract: A semiconductor device including a first oxide definition (OD) strip doped by a first-type dopant in a first doping region defining an active region of a first Metal-Oxide Semiconductor (MOS); a second OD strip doped by a second-type dopant in a second doping region and a third doping region, the second doping region defining an active region of a second MOS and the third doping region defining a body terminal of the first MOS, wherein the second OD is parallel to the first OD strip; and a first dummy OD strip, wherein a boundary between the second doping region and the third doping region is formed over the first dummy OD strip; wherein the first-type dopant is different from the second-type dopant.

Abstract: A portable electronic device including a first body, a second body, and a hinge mechanism is provided. The second body is connected to the first body through the hinge mechanism, and the hinge mechanism has a basis axis located at the first body and a rotation axis located at a lower end of the second body. When the second body rotates with respect to the first body, the rotation axis slides along an arc shaped path with respect to the basis axis to increase or decrease a distance between the rotation axis and the basis axis and increase or decrease a distance between the lower end of the second body and a back end of the first body.

Abstract: An apparatus of power generation is provided. The apparatus uses a stack of dense solid oxide fuel cells (SOFC). The exhaust gas generated by a burner of the apparatus enters into the SOFC stack for heating. At the same time, the SOFC stack is heated by the thermal radiation and heat transfer of the burner as well as the thermal convection of gases between the anode and the cathode. Thus, the SOFC stack is heated to reach an operating temperature for generating power without any additional electroheat device. The present invention has a simple structure, flexible operation. Moreover, it increased efficiency, reduced pollutant emission with lowered costs of equipment and operation.

Abstract: Thermotechnical units of solid oxide fuel cell (SOFC) are integrated as a whole one. The units may include a burner, a reformer and a heat exchanger. The integrated units can be easily assembled into an SOFC system with cell stacks. Thus, the present invention has a simple structure, operates with ease, saves operational cost, runs with fewer utilities, decreases heat dissipation and enhances system performance.

Abstract: A burner reformer is provided for a power generating system using fuel cell. A burner is contained inside the reformer. The reformer absorbs heat from the burner and other heat source to reduce heat loss and save connecting wires. The present invention avoids flashing back of hydrogen. When fuel is lean, flame would not easily die and the system can thus work stably.

Abstract: An apparatus for detecting abnormality in an LED (light-emitting diode) vehicle lamp includes a detecting module and a warning module . The LED vehicle lamp includes a plurality of LEDs. The detecting module is to be electrically coupled to the LED vehicle lamp for acquiring voltage information that represents an operating voltage level of the LED vehicle lamp, and determines based on the voltage information thus acquired whether the LED vehicle lamp may have functioned abnormally. The warning module is electrically coupled to the detecting module to be driven thereby to generate a warning message when the result of determination by the detecting module indicates that the LED vehicle lamp may have functioned abnormally.

Abstract: A burning device is provided for fuel cell to be run under high temperature. The burning device uses a specific-designed fuel spraying device having porous medium. The burning device can be used under different statuses of flow in the fuel cell. With the burning device, the fuel cell has improved efficiency by enhancing recycling of system heat and pollution of discharged waste gas is reduced.
