Patent number: 5120146Abstract: A printer having a bail roller opening and closing apparatus including a bail roller for pressing a printing medium against a platen, a bail roller opening and closing mechanism for moving the bail roller between a closed position and an open position, and a clutch for connecting a space motor to the bail roller opening and closing mechanism. The bail roller opening and closing mechanism includes a rotating member rotationally driven by the space motor via the clutch, a transmission member causing the bail roller to be displaced by displacement of the transmission member and manual displacement of the bail roller, and a bidirectional motion transmission mechanism for transmitting bidirectional motion between the rotating member and the transmission member.Type: GrantFiled: August 6, 1991Date of Patent: June 9, 1992Assignee: Fujitsu LimitedInventors: Hirofumi Nakayasu, Chikako Kawana, Masaki Kanoh, Kenji Umehara, Yoshiaki Hosokawa, Takashi Maekawa

Patent number: 4432924Abstract: An electrically conductive thermoplastic resin monofilament having a high mechanical strength and an excellent electrical conductivity is produced. This monofilament containing an electrically conductive carbon black is produced through extrusion, cooling, aging, and orientation steps, the temperature of the monofilament in the orientation step is within the range of from 60.degree. C. to 5.degree. C. less than the melting point of the thermoplastic resin, and orientation is carried out at a stretching strain rate of 5000%/min or less. Also in the aging step the temperature is optionally kept constant.Type: GrantFiled: April 9, 1982Date of Patent: February 21, 1984Assignee: Lion CorporationInventors: Kenji Umehara, Hiroshi Takeda, Susumu Tomidokoro
