    摘要： The present disclosure provides a production method for producing an exhaust gas purification catalyst with a reduced standby time of a shower nozzle. The method includes: a slurry supply step of supplying a catalyst metal-containing slurry from a shower nozzle to one end of a honeycomb base material; a first suction step of pressurizing or depressurizing the base material on which the slurry has been supplied, in a direction of the other end of the base material by using a first suction device to draw the slurry supplied, into the base material; and a second suction step of further pressurizing or depressurizing the base material after the first suction step, in the direction of the other end of the base material by using a second suction device. The slurry supply step and the first and second suction steps are performed in parallel in the same production line.

    摘要： The present invention provides a catalyst body for purifying an exhaust gas from a gasoline engine which exhibits high NH 3 purification performance after endurance. A catalyst body for purifying an exhaust gas from a gasoline engine disclosed here is configured to be disposed in an exhaust path of a gasoline engine. The catalyst body for purifying an exhaust gas includes: a base material; an NH 3 adsorption layer containing zeolite; and a catalyst layer containing a catalytic noble metal. The NH 3 adsorption layer and the catalyst layer are stacked such that the NH 3 adsorption layer is located closer to the base material than the catalyst layer. The NH 3 adsorption layer includes a front portion and a rear portion, the front portion being located on an upstream side in an exhaust gas flow direction, a rear portion being located downstream of the front portion in the exhaust gas flow direction, when the catalyst body for purifying an exhaust gas is disposed in the exhaust path. The front portion contains metal-supported zeolite. The rear portion contains proton-type zeolite. The catalyst layer covers the front portion and the rear portion of the NH 3 adsorption layer.

    摘要： One aspect of the present disclosure is a power-supply apparatus (1; 300) to supply an electric power to an electric working machine e (50; 500; 500A; 500B) including a trigger switch (51; 510), a motor (60; 600), and a tool (65; 650). The power-supply apparatus includes a connection detector (12; 350), a trigger detector (12; 350), and a signal outputter (12; 350). In response to (i) the connection detector detecting connection of the electric working machine to the power-supply apparatus, and also to (ii) the trigger detector detecting an ON state of the trigger switch, the signal outputter outputs, to the electric working machine, a discharge prohibition signal prohibiting supply of the electric power to the motor, until an OFF state of the trigger switch is detected once by the trigger detector.

    摘要： A rotor for a rotating electrical machine is disclosed that includes: a rotor core having a radially outer first magnet hole and a radially inner second magnet hole; a first permanent magnet in the first magnet hole; and a second permanent magnet in the second magnet hole. The rotor core includes a first portion located radially outward of the first magnet hole, a second portion located between the first magnet hole and the second magnet hole, a third portion located radially inward of the second magnet hole, and bridge portions connecting the third portion and the second portion. A separation distance of the second permanent magnet from the first permanent magnet is smaller at a position closer to the bridge portion in a circumferential direction than at a position farther from the bridge portion in the circumferential direction along a side of the second permanent magnet that faces the first permanent magnet, as viewed in an axial direction. At least one of the plurality of bridge portions extends radially inward beyond a radially inner edge of a circumferential end of the second permanent magnet facing the at least one bridge portion in the circumferential direction.
