An ink furnishing apparatus for a printing press for performing printing by furnishing an ink to a printing plate on a plate cylinder is selectively operable in an entire surface ink furnishing mode, in which a first gap is held fully opened, the doctor means is placed in contact with the metering roller, ink drawn through the fully opened first gap in a thickness corresponding to the first gap by rotation of the fountain roller, is furnished in an excess amount of ink onto the peripheral surface of the metering roller, the extra amount of ink on the peripheral surface is scraped off by means of the doctor means contacting with the peripheral surface of the metering roller to return to the ink fountain, and the ink is furnished onto a printing plate in a plate cylinder via the peripheral surface of the form roller in substantially uniform amount over the entire position along the axis of the metering roller, and in a local ink furnishing mode, in which the first gap is adjusted to be narrower with respect to divided divided zones by adjusting means, the doctor means is released away from the peripheral surface of the metering roller, the ink drawn from the ink fountain by rotation of the fountain roller per each separated zones in the desired thickness is furnished on the peripheral surface of the metering roller.

A web width adjusting device can adequately adjust the width of paper web which is travelled through at least two printing sections. The travelling web is sandwitched by a pair of contact means including a plurality of contact members which are aligned in parallel to the axis of cylinders for driving the paper web. The contact members of one alignment are alternatively in contact with the web surface with respect to the other alignment.

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.

In production of a shell-type golf club head made up of several different pieces, an iron-type material of a specified chemical composition and carbon equivalent is subjected to a combination of annealing before shaping with quenching after shaping. Exclusion of the conventional casting process in production much improves mechanical characteristics of the product and increase mechanical strength enables formation of a large size golf club head with an enlarged sweet spot. Limited and locally specified disposition of weld lines assures highly accurate lie and loft angles with reduced welding strain.

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:
When spot printing is made by opposed blanket cylinders for spot printing that are disposed on one of a pair of blanket cylinders disposed to oppose each other in a rotary press, the present invention discloses a spot printing method characterized in that a suitable number (more than two) of blankets are selected from inside the range of division width obtained by dividing the full width range of the blanket cylinder for spot printing into a suitable number (more than two) of widths and are then fitted to the blanket cylinder for spot printing, and printing is then made by the blanket cylinder for spot printing.The present invention discloses also a blanket cylinder for spot printing which comprises a suitable number (more than two) of blankets of a width within the range of division width obtained by dividing the full width range of a blanket cylinder; and blanket fitting devices operative independently of one another within the range of division obtained by dividing the full width range of the blanket cylinder.

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.
