Abstract: A vehicle display system, by executing a computer-readable program, being configured to: display multiple image contents in separate display areas of a display device arranged in a vehicle; detect a visual field range of an occupant of the vehicle; determine whether a frame rate of a certain image content displayed in the visual field range satisfies a lowest reference, the certain image content being one of the multiple image contents; and in response to determining that the frame rate of the certain image content does not satisfy the lowest reference, reduce a processing load of a different process while maintaining a display process of the certain image content in the visual field range of the occupant.

Abstract: A solder drawing member (402) is detachably attached on the outer side of a jet nozzle (303) that jets molten solder pumped from a solder tank (102) storing the molten solder. The solder drawing member (402) is made of a material having higher wettability to the molten solder than the surface material of the jet nozzle (303). Thus a force of separating the solder from a point to be soldered can be increased by a surface tension of the molten solder flowing on the solder drawing member (402), thereby reducing bridge phenomena and icicle phenomena.

Abstract: The present invention provides a reflow apparatus and method effective to make constant the internal gas flow direction in a heating section within a reflow furnace. A circulating gas path is formed in a heating unit which collects and causes the gas to flow from a sirocco fan, up the rear side of the heating unit and then down towards a circuit board moving along a transfer path at the front side of the heating unit. Moreover, a plurality of straightening plates are arranged above the transfer path of the heating unit so as to guide the hot gas, which is flowing forwardly downwardly toward the circuit board moving along the transfer path. A blow-down nozzle is provided and includes a plurality of plates aligned in rows in the transferring direction of the circuit boards. The plates have an inverse U-shaped cross section. The blow-down nozzle is arranged below the straightening plates to cause the vertical hot gas flows to flow uniformly over the whole surface of the circuit board.
