  • Publication number: 20250235852
    Abstract: The present disclosure provides an exhaust gas purification catalyst improved in structural stability. The present disclosure relates to an exhaust gas purification catalyst including a substrate and a catalyst layer disposed on the substrate. The catalyst layer has a two-layer structure including a first coat layer formed on the substrate and a second coat layer formed on the first coat layer. The first coat layer contains alumina and an OSC material. The alumina has an average particle diameter of 6.0 ?m or more, and the OSC material has an average particle diameter of 6.0 ?m or more. The OSC material is a ceria-zirconia-based composite oxide without alumina.

    Abstract: An exhaust gas purification catalyst includes a substrate and a catalyst layer on the substrate. The catalyst layer includes lower and upper catalyst layers. The lower catalyst layer includes a powder material containing a powdered carrier, and catalyst metal particles containing Rh on the carrier. The upper catalyst layer includes an upstream catalyst layer in an upstream side in an exhaust gas flow direction, and a downstream catalyst layer in a downstream side in the exhaust gas flow direction. At least the upstream catalyst layer of the upstream and downstream catalyst layers includes a powder material containing a powdered carrier, and catalyst metal particles containing Pd on the carrier. A cumulative 50% particle size D50 in a volume-based particle size distribution of the powder material included in at least the upstream catalyst layer of the upstream and downstream catalyst layers is 6 ?m or more and 10 ?m or less.

  • Publication number: 20250033208
    Abstract: This teaching operation panel sends out a command to a robot control device for controlling the actions of a robot. The teaching operation panel comprises a voice input unit by which a user inputs voice commands, and a voice recognition unit for recognizing a voice command acquired by the voice input unit. The teaching operation panel also comprises a processing unit that, on the basis of the result of voice recognition by the voice recognition unit, transmits at least one command from among operations in an action program of the robot and termination of alarms to the robot control device.

  • Publication number: 20240139716
    Abstract: Provided is an exhaust gas purification catalyst providing a catalyst performance and an OSC performance at the same time even at low temperature. The present disclosure relates to an exhaust gas purification catalyst including a substrate and a catalyst coating layer coated on the substrate. The catalyst coating layer includes a first catalyst coating layer containing Pd and/or Pt and a second catalyst coating layer containing Rh. The first catalyst coating layer is formed from an end portion in an upstream side with respect to an exhaust gas flow direction in the exhaust gas purification catalyst. The second catalyst coating layer includes an upstream coating layer and a downstream coating layer. Rh in the upstream coating layer and the downstream coating layer are supported on specific carrier particles. Further, a particle diameter of Rh is controlled.

  • Patent number: 10543811
    Abstract: A wiper system performs operation control on wiper driving electric motors and based on position information about wiper blades and attached to pivot shafts, wherein a learning mode in which a position of the wiper blades is learned to correct blade position information is executed after the wiper blades are attached to the pivot shafts, respectively. In the learning mode, the wiper blades are moved to a prescribed position such as a lower retracted position, and that the wiper blades are located in the prescribed position is detected by such means as a sensor, a video image, and contact with a jig. If the wiper blades are detected to be in the prescribed position, the blade position information is corrected to a value corresponding to the position.

  • Patent number: 6797092
    Abstract: A method for manufacturing a monolithic ceramic electronic component formed by using a laminate allows a plurality of types of ceramic green sheets to be laminated with ease and efficiency. The method enables a reduction in space for lamination. This method includes first, a ceramic green sheet with a predetermined shape is cut out of a long first ceramic green sheet supported on a carrier film by a cutting/laminating head. The cut-out ceramic green sheet is laminated to the cutting/laminating head. A card-like second ceramic green sheet supported on a carrier film is cut by a cutting/laminating head. The cut ceramic green sheets is laminated to the cutting/laminating head. A laminate is formed by performing each of the first and second steps plural times.
