摘要： A catalyst for purifying exhaust gases includes a substrate, and a catalytic layer. The catalytic layer includes a lower catalytic layer, a first upper catalytic layer, and a second upper catalytic layer. The lower catalytic layer being loaded with Pd and/or Pt is formed on the substrate. The first upper catalytic layer being loaded with Pd covers an upstream side of the lower catalytic layer, and exhibits a concentration of loaded Pd that falls in a range of from 4.5 to 12% by mass when the entirety of the first upper catalytic layer is taken as 100% by mass. The second upper catalytic layer being loaded with Rh covers a downstream side of the lower catalytic layer.

摘要： A multiplexer receives multiple differential signals, selects one differential signal, and outputs, via an output port, the differential signal thus selected. The multiple differential signals are respectively input to multiple differential input ports. Multiple buffers are respectively provided to the multiple differential input ports. Each buffer includes a differential input terminal connected to a corresponding differential input port, and a differential output terminal connected to an output port. Each buffer is configured to be capable of switching states, according to the control signal, between an enable state in which a differential signal that corresponds to a differential signal input to the differential input terminal is output, and a disable state in which current consumed by the buffer becomes substantially zero, and the differential output terminal thereof is set to a high-impedance state.

摘要： An exhaust gas purification catalyst is provided with a substrate and a catalyst coating layer formed on the surface of the substrate. The catalyst coating layer is formed into a layered structure having upper and lower layers, with a lower layer being closer to the surface of the substrate and an upper layer being relatively farther therefrom. The catalyst coating layer is provided with Rh and Pd as precious metal catalysts and is provided with an OSC material having an oxygen storage capacity as a support. The Rh is disposed in the upper layer of the catalyst coating layer, and the Pd is disposed in both the upper layer and the lower layer of the catalyst coating layer. At least a portion of the Pd in the upper layer and in the lower layer is supported on the OSC material. The mass ratio of the Pd disposed in the upper layer to the Pd disposed in the lower layer is not more than 0.4.
