  • Publication number: 20060077770
    Abstract: This invention provides a disk playback apparatus which can shorten a time from when a power switch is turned on until a startup operation is completed. Even when the power switch of the main body is OFF, if exchange of a disk-like recording medium is detected, management data of the disk is read out and is stored in a buffer memory. When the power switch is turned on for the next time, the management data is read out from the buffer memory without accessing the disk-like recording medium.

  • Patent number: 6237484
    Abstract: A screen printing apparatus 199, 169 has a roll paper vibrating device which vibrates roll paper in contact with the lower surface of a screen mask in a direction perpendicular to a moving direction of the roll paper while the roll paper is being moved in contact with the lower surface of the screen mask. Thereby, the roll paper in contact with the lower surface of the screen mask is moved in a waveform-shape pattern. Therefore, the cumulative contact area of the roll paper on the lower surface of the mask is increased, and it is possible to efficiently remove residue, such as paste attached onto the lower surface of the screen mask of the printing apparatus and paste attached inside pattern openings of the screen mask, to maintain a good printing performance.

  • Patent number: 5266022
    Abstract: A brush holder structure in an electric motor in which brush holders for housing brushes held in slidable contact with a commutator provided on a rotor shaft and an end bracket for rotatably supporting the rotor shaft are both integrally molded with a gear frame for housing and supporting a worm gear mechanism. In addition to the main mold for molding the gear frame, two first molds and two U-shaped second molds are abutted so as to form the brush holders when the gear frame is molded. A projection extending from each of the first molds extends between the arms of the associated U-shaped second molds to form a lead-out groove for leading out a pig tail extended from each brush.
