  • Publication number: 20020196485
    Abstract: When a digital copying machine is switched on, a main CPU confirms whether the current timing is a timing at which an advertisement can be displayed on a display section. If operational inputs are being performed from the display section in the digital copying machine, the advertisement cannot be displayed and thus a normal image forming operation is controlled. If operational inputs are not being performed from the display section and the current timing is the timing at which the advertisement can be displayed, it is conformed whether an HDD stores a registered image as an advertisement image. If there is at least one registered image in the HDD, the at least one registered image is displayed on the display section at predetermined time intervals at the timing of the advertisement display in accordance with the priority level. The registered image in the HDD, whose remaining designated display time has reduced to zero, is deleted.

  • Patent number: 6442834
    Abstract: In the method of manufacturing substrate-use terminals in accordance with the present invention, a rectangular wire 10 is first subjected to cylindrical shaping to form a substrate-side terminal portion 22. Next, a loss portion 14, which is a connecting portion between a tip portion 22a of the substrate-side terminal portion 22 and a tip portion 21a of a connector-side terminal portion 21 and is not used as a portion of a substrate-use terminal 20 after being cut off, is subjected to cutting so as to provide primary machining for the tip portions 21a and 22a. Subsequently, the connector-side terminal portion 21 and the substrate-side terminal portion 22 are subjected to tip crushing to provide secondary machining for the tip portions 21a and 22a. Next, a retaining section 23 for engagement in a connector housing is formed, and the loss portion 14 is finally cut off to form the single-unit substrate-use terminal 20.

  • Patent number: 6437874
    Abstract: An image forming apparatus includes a scanner for reading image information of an original, a memory for storing the image information of a plurality of originals read by the scanner, a printer for forming the image information of at least two of the originals stored in the memory on a single image formation medium, a detector for detecting that the memory becomes full, and a controller. When the detector detects that the memory becomes full while the scanner is performing a series of read operations, the controller controls the printer to print images of the image information of originals which are stored in the memory and images of which are to be formed on a single sheet, erases the image information whose images are printed, and controls the scanner to restart reading of the originals.

  • Patent number: 6406338
    Abstract: Board terminals 12, each including a tapering insertion portion 13 for insertion into a through hole in a board, a soldering portion 14 to be soldered to the board, and a connection portion 15 for connection to a mating terminal, are produced from a wire 11, the insertion portion, the soldering portion and the connection portion being continuously arranged in this order in a direction of a length of the board terminal. The wire 11 has a width larger than a thickness thereof. The insertion portion 13 is formed by pressing the wire, and the soldering portion 14 is formed by cutting or pressing widthwise opposite side portions of that portion of the wire extending from the insertion portion 13, the soldering portion having a width smaller than the width of the wire. Those portions, removed from the wire by cutting or pressing, are very small, and generally the whole of the wire can be formed into the board terminal, and therefore a loss of the material is reduced.

  • Publication number: 20020045382
    Abstract: A portion (21a) of each electric wire of a flat cable (20), defining a bottom portion of a bent portion thereof, is electrically press-connected to a press-connecting blade (13a) of a male terminal (13). Portions (21b, 21c) of the electric wire, disposed respectively at the front and rear sides of the electrically-connected portion of the electric wire, ride on wire holding ribs (14a, 14b), respectively. The ridden portions (21b, 21c) of the electric wire are pressed and held by a wire holding cover (16). The ridden portions (21b, 21c) of the electric wire bear the burden of a tension or a stress due to a pulling force applied to the flat cable, and therefore the tension will not act on the electrically-connected portion of the electric wire, press-connected to the press-connecting blade (13a).
