Abstract: A method and an apparatus for collecting flux are disclosed. A rosin particle contained in an atmosphere gas, and a vapor of a solvent or an atomized solvent particle are mixed in a mixing section upstream of a flux collection unit-side inlet, and a gas containing a mixed particle is cleaned by electrostatic precipitation. The solvent particle adheres to the rosin particle, and forms an aggregate of larger particle size.

Abstract: A fuel cell includes: an electrolyte membrane; a fuel-side catalyst layer placed on one surface of the electrolyte membrane; an oxidant-side catalyst layer placed on another surface of the electrolyte membrane; a fuel-side gas-diffusion layer placed on a main surface of the fuel-side catalyst layer; an oxidant-side gas-diffusion layer placed on a main surface of the oxidant-side catalyst layer; a pair of separators that hold the fuel-side gas-diffusion layer and the oxidant-side gas-diffusion layer therebetween; a frame that surrounds outer peripheries of the fuel-side gas-diffusion layer and the oxidant-side gas diffusion layer; a fuel-side seal member placed on a main surface of the fuel-side gas-diffusion layer; and an oxidant-side seal member placed on a main surface of the oxidant-side gas-diffusion layer. In the fuel cell, no spaces are provided between the fuel-side gas-diffusion layer and the fuel-side catalyst layer and between the oxidant-side gas-diffusion layer and the oxidant-side catalyst layer.

Abstract: A base material is welded by a first welding method in a case where a welding parameter related to heat input to the base material is less than a first threshold value. The base material is welded by a second welding method in a case where the welding parameter is less than a second threshold value and is more than the first threshold value. The base material is welded by a third welding method in a case where the welding parameter is more than the second threshold value. By adjusting welding conditions regardless of the thickness of the base material, a welding method suitable for the thickness of the base material is determined to provide a welding with little spatter and no meltdown of the base material.

Abstract: A first wireless device is mountable in a vehicle. An acquiring unit acquires position information on the vehicle in which the first wireless device is mounted. A calculating unit calculates a difference between the position information acquired by the acquiring unit and an ideal route for the vehicle. A communication unit transmits a packet signal that contains the difference calculated by the calculating unit and the position information acquired by the acquiring unit.

Abstract: A small antenna device having good communications performance and a wide communications area even when a metal plate is present in the antenna communications direction, even when the antenna is arranged, for example, inside a box-shaped metal case, and even when a through hole is used that has a smaller area than the antenna. This device comprises: the antenna (8); a rear surface cover (3) overlapping with the antenna (8) and being a conductor that faces the winding of the antenna (8); two first insulating areas (10a) provided in the rear surface cover (3) and extending in a direction that intersects the winding axis of the antenna (8); and a second insulating area (10b) that connects between the first insulating areas (10a). At least part of the area sandwiched by the first insulating areas (10a) faces the antenna (8).
