TL;DR: In this paper, a fuel battery cell C includes a membrane electrode assembly having a frame 1 in a periphery of the battery cell and two separators 3A, 3B holding them there between.
Abstract: A fuel battery cell C includes a membrane electrode assembly 2 having a frame 1 in a periphery thereof; two separators 3A, 3B holding them therebetween; and gas seal members 11, 12 provided to peripheral portions of diffuser areas D1, D2 each formed between the frame 1 and one of the separators 3A, 3B A diffuser-area-D1-side edge position of the gas seal member 11 in the diffuser area D1 on the cathode side and a diffuser-area-D2-side edge position of the gas seal member 12 in the diffuser area D2 on the anode side are offset from each other in an inside-outside direction of the diffuser areas D1, D2

TL;DR: In this article, a support plate, plural LEDs, a reflection piece, an auxiliary diffuser plate and a diffuser piece are arranged on the support plate to orient the light to the diffuser.
Abstract: The invention is a LED backlight module, including a support plate, plural LEDs, a reflection piece, an auxiliary diffuser plate and a diffuser piece. These LEDs are arranged on the support plate. The auxiliary diffuser plate is arranged above these LEDs and the surface of the auxiliary diffuser plate has plural optical microstructures, and the diffuser piece is arranged above the auxiliary diffuser plate at a preset height. The light generated by the LEDs can be totally reflected from the auxiliary diffuser plate and diffuser piece and mixed in the LED backlight module and leave the LED backlight module from the top surface of the diffuser piece and these optical microstructures orient the light to the diffuser piece.

TL;DR: In this article, a method and system for heating a circuit board component to an approximately uniform temperature sufficient to reflow the connections between circuit board components and the circuit board is presented.
Abstract: A method and system for heating a circuit board component to an approximately uniform temperature sufficient to reflow the connections between the circuit board component and the circuit board. The method and system include a supplemental gas heater having a diffuser plate. The circuit board is placed against the diffuser plate and heated gas is channeled through openings in the diffuser plate into vias in the circuit board to heat a circuit board component connected on the opposite side of the circuit board. Heated gas can be channeled through selected vias towards predetermined areas and/or specified connections such as towards those areas or connections where there is a temperature differential greater than approximately 10 degrees Celsius compared to other areas or connections across the circuit board component. Hot gas can be channeled through selected vias by baffling or patterning the diffuser plate, accordingly.
