摘要： Disclosed are methods for production of plastic optical fiber connectors specifically for production of plastic plug ferrules employable for plastic optical fiber connectors, wherein improvements are realized to decrease the production cost thereof, to enable accurate finished dimension thereof, to enhance the advantage of mass production thereof, and to decrease the connection loss thereof. The method comprises (1) a step to produce a round hole at the center of one end of a rod, the round hole having a diameter approximately identical to that of a bare fiber of optical fibers to be connected with each other, (2) a step to insert a pin to the round hole to produce a master mold, (3) a step to employ an electroform process such as a nickel plating process to plate a metal layer to a predetermined thickness on the external surface of the master mold for the purpose to produce an electroformed mass, (4) a step to draw the master mold from the electroformed mass, remaining the pin alone in the electroformed mass, for the purpose to produce an electroformed mold, (5) a step to produce a metal mold by assembling the electroformed mold, a pipe and a pair of upper and lower metal dies, and (6) a step to fill a molten resin or plastic into the cavity of the metal mold for the ultimate purpose to produce a plastic plug ferrule to be assembled in a plug employable for a plastic optical fiber connector.

摘要： This invention relates to a document processing apparatus which edits document data which can define a desired section using an original page as a unit of definition. Whether a page break is designated at the section break of the section is determined. If the page break is designated, a blank original page is inserted at the end of a section before the section break so as to lay out the first original page of a section after the section break at the start of a new surface of a print sheet when original pages are laid out in accordance with a designated layout.

摘要： A transmission device including a detection unit, a processing unit and a transmission unit. The detection unit detects whether there are plural consecutive transmission elements in which absolute values of differences between lengths of the transmission elements are equal to or less than a pre-specified value. If intermission periods are not provided in the detected transmission elements, the processing unit performs processing that inserts at least one of an irregular signal and an intermission period into at least one of the transmission elements. If intermission periods are provided in the detected transmission elements, the processing unit performs at least one of processing that changes a length of the intermission period provided in at least one of the detected transmission elements and processing that inserts an irregular signal into at least one transmission element. The transmission unit transmits the processed transmission elements in an order of a transmission element group.
