  • Publication number: 20200103809
    Abstract: A medium cutting device includes first and second conveying sections and a cutting section. The first conveying section conveys a continuous medium having a perforation that extends in a first direction. The first conveying section conveys the continuous medium in a second direction intersecting the first direction. The second conveying section is spaced from the first conveying section in the second direction, and conveys the continuous medium in the second direction. The cutting section includes a pressing member and a supporting member. The pressing member is movable in the first direction in a gap between the first and second conveying sections. The supporting member movably supports the pressing member in the second direction. The cutting section causes the pressing member to press the continuous medium while causing the pressing member to move in the first direction, thereby cutting the continuous medium at the perforation.

  • Patent number: 9567127
    Abstract: A medium transporting apparatus is used for transporting a label web including a carrier web and labels adhered thereto. A platen roller transports the label web in a transport path. A pressure roller is disposed downstream of the separating member with respect to the transport path, and causes the carrier web to be kinked. The pressure roller urges the carrier web against the platen roller. A support member is mounted on a cover and rotatably supports the pressure roller. The cover is pivoted between an open position and a closed. Immediately after the cover has moved to the closed position, the pressure roller contacts the platen roller and then slides by a predetermined amount on the circumferential surface of the platen roller in a direction away from the separating member. Thus, the carrier web sandwiched between the pressure and platen rollers becomes taut.

  • Patent number: 9498771
    Abstract: To provide an exhaust gas catalyst using a fired aluminum phosphate body with more excellent performance, and a method for producing it. (1) An exhaust gas purification catalyst including at least one platinum-group metal selected from the group consisting of Pt, Rh and Pd having a mean particle diameter of between 0.50 nm and 2.0 nm, supported on a tridymite-type fired aluminum phosphate body. (2) A method for producing an exhaust gas purification catalyst, including the steps of: firing aluminum phosphate obtained from an aqueous solution prepared to a pH of 3.5 to 4.5, at a temperature of between 1000° C. and 1200° C. for 2 hours or longer, to obtain a fired aluminum phosphate body, and supporting at least one type of platinum-group metal selected from the group consisting of Pt, Rh and Pd on the fired aluminum phosphate body.

  • Patent number: 9067193
    Abstract: An exhaust gas purifying catalyst, which is obtained by having at least one platinum group metal selected from the group consisting of Pt, Rh, and Pd supported on a calcined aluminum phosphate body. The calcined aluminum phosphate body has a tridymite crystal structure and the ratio of the cumulative pore distribution of pores having a size of 10 nm or less to the cumulative pore distribution of pores having a size of 300 nm or less is 20% or more in the calcined aluminum phosphate body. A method for producing an exhaust gas purifying catalyst including calcining aluminum phosphate, which has been obtained from an aqueous solution that is controlled to have a pH within a predetermined range, at a predetermined temperature for a predetermined period of time, thereby obtaining a calcined aluminum phosphate body; and having at least one platinum group metal selected from the group consisting of Pt, Rh, and Pd supported on the calcined aluminum phosphate body.
