Abstract: A technique advantageous for improving an optical property of a photoelectric conversion apparatus is provided. The photoelectric conversion apparatus includes a photoelectric conversion layer and a light-shielding film that covers the photoelectric conversion layer, wherein the light-shielding film includes one metallic layer and another metallic layer located between the one metallic layer and the photoelectric conversion layer.

Abstract: A method of coating a powder lubricant in a metallic injection molding machine having a die composed of a stationary die (2) and a movable die (10), a sprue hole (4), runner groove (5), gate hole (6) and cavity (7) being formed on parting faces (P) of these dies (2, 10), a cold plug catcher (13) communicating with the sprue hole (4) when the movable die (10) is fastened to the stationary die (2) being formed in the movable die, the method of coating a powder lubricant in a metallic injection molding machine comprising the step of coating the powder lubricant from the cold plug catcher (13) toward the cavity (7) by decompressing the inside of the sprue hole, runner groove, gate hole and cavity from the cavity side.

Abstract: Physically and chemically stable insecticidal preparation in the form of aqueous emulsion or suspension is provided wherein active ingredients which are oily or solid and hardly soluble or insoluble in water are mixed in water with nonionic surfactants having an HLB value of 11 or less and thickeners.

Abstract: A method of indirect spot welding two or more members together, comprising the steps of pressing electrodes against at least one of the members, flowing a square wave current between the electrodes and across the members during a first time period, pausing the flow of current, flowing a square wave current between the electrodes and across the members during a second time period, and stopping the flow of current.

Abstract: A method for facilitating the assembly of a structural panel and for preventing the sag thereof comprises the step of placing the structural panel (2), comprising an outer plate (6) and an underlying skeleton framework (7), upon longitudinally extending support beams (B') which interconnect the upper ends of laterally spaced rows of longitudinally spaced support columns (C) which extend upwardly from a floor support surface (F). A mobile radiation heating element truck (4), movable upon laterally spaced rails (8) by means of casters (11), includes radiation heating elements (12).

Abstract: A spot welder comprising a movable truck which is movable along a workpiece, and first, second and third electrodes supported on the truck. The first and second electrodes are adapted to pair with each other for series welding, and one of the first and second electrodes is adapted to pair with the third electrode for indirect welding. Depending on the state of the site of the weld, welding can be performed by selectively using either series or indirect-spot welding. Mechanisms are provided for easily and rapidly switching between the two welding types.

Abstract: Apparatus for facilitating the assembly of a structural panel and for preventing the sag thereof comprises an upstanding support structure in the form of laterally spaced rows of longitudinally spaced columns (C) which extend upwardly from a floor support surface (F). Longitudinally extending support beams (B') interconnect the upper ends of the support columns (C), and the structural panel (2) comprising an outer plate (6) and an underlying skelton framework (7) is supported upon the support beams (B'). A radiation heating element truck (4), movable upon laterally spaced rails (8) by means of casters (11), include radiation heating elements (12) mounted upon a support panel (5) whereby the truck (4) is movable between first and second operative positions or stages (A, B).
