    摘要: A rotary press includes a plurality of cylinders including plate cylinders arranged to perform printing. Each of the plate cylinders is supplied with ink through an inking unit which is associated with the plate cylinder. The inking unit is composed of at least one of form rollers, an ink metering roller which is in contact with an ink metering doctor blade, and a fountain roller partially dipped in an ink fountain pan. At least one of the inking units further includes an intermediate roller interposed between the upperstream side of the form roller(s) and the downstream side of the metering roller when the ink fountain pan is located above the plate cylinder to be supplies with ink through the inking unit. The intermediate roller can freely change the revolving direction of the metering roller so that the ink metering doctor blade can be arranged at any proper position where is no obstruction to adjust the contact angle of the doctor blade onto the mesh roller and repair or replace the doctor blade per se.

    摘要: A drag roller device for a printing apparatus comprises a cleaning means for cleaning a drag roller. The cleaning means is in contact with a part of the circumferential surface of the drag roller except for the circumferential area around which a printed continuous sheet fed from a printing section is wound. The cleaning means may be movable within the circumferential area of the drag roller or separable from it. The cleaning means may be supplied with a cleaning liquid.In the drag roller device thus constructed, the cleaning means can remove various stains and/or spots of ink transferred from the circumferential surface of the drag roller and/or additional rollers at each revolution of the drag roller. This cleaning operation of the cleaning means ensures to prevent the printed surface of the continuous sheet succeedingly fed from damaging with the stains and spots of ink from the drag roller and so on.

    摘要: The present invention relates to a fuel cell exhibiting a high performance regardless of the humidification conditions. In short, it is a fuel cell comprised of a proton-conducting electrolyte membrane sandwiched between a pair of catalyst layers, wherein a catalyst layer of at least a cathode contains a catalyst ingredient, electrolyte material, and carbon material; the carbon material is comprised of three types of materials of a catalyst-supporting carbon material supporting the catalyst ingredient, a conductivity-aiding carbon material not supporting the catalyst ingredient, and a gas-diffusing carbon material not supporting the catalyst ingredient; the catalyst layer is comprised of two phases of a catalyst aggregated phase having the catalyst-supporting carbon material supporting the catalyst ingredient and the conductivity-aiding carbon material not supporting the catalyst ingredient aggregated as main ingredients and a gas-diffusing carbon material aggregated phase having the gas-diffusing carbon material not supporting the catalyst ingredient aggregated as a main ingredient; and the catalyst aggregated phase is a continuous phase while the gas-diffusing carbon material aggregated phase is dispersed in the catalyst aggregated phase.
