Patent number: 5896290Abstract: A man-machine interface system for a process controller according to the present invention enables its direct picture select button function to be effectively used by each user, and is improved in the operability of picture selection for interrupt display. The system includes a display, a picture data controller for controlling the pictures, which are displayed on the display, and at least one direct picture select button for requesting the display of an interrupt picture on the display to set control requirements and monitor operating conditions with the controller. In response to the interrupt picture display request by the button, a specified picture is displayed as an interruption on the display. The system further includes an interrupt picture definition table for setting by the user to changeably define on a user's setting picture the picture for interrupt display. The interrupt picture set by the user can be displayed independently of the initialization hierarchy by only operating the button.Type: GrantFiled: March 29, 1996Date of Patent: April 20, 1999Assignee: Toshiba Kikai Kabushiki KaishaInventors: Hiroshi Katsuta, Yutaka Yamaguchi, Masamitsu Suzuki, Kiyoshi Sasaki, Shoji Hayashi

Patent number: 5694638Abstract: An image generating device is provided with a control mechanism which controls an exit paper delivery speed after an image has been fixed to a form. The exit paper delivery speed is changed depending on information detected about the process of generating the image to prevent the form from being delivered with wrinkles. The information detected includes size of paper intervals between forms, length of forms, and whether the image generating process is a repeat copying or continuous form feeding process.Type: GrantFiled: July 12, 1996Date of Patent: December 2, 1997Assignee: Ricoh Company, Ltd.Inventors: Yuichi Maruyama, Junji Nakai, Sakae Ishikawa, Hiroyuki Gotoh, Shoji Hayashi

Patent number: 5088713Abstract: A paper refeeding device incorporated in an image forming apparatus for temporarily stacking paper sheets each coming out of an image forming section and carrying an image on one side on a refeed tray and, then, refeeding the paper sheets to the image forming section. An air velocity switching mechanism causes an air knife to blow air at a breeze velocity or a zero velocity which does not lift the paper sheets stacked on the refeed tray, until more than a predetermined number of paper sheets have been discharged by discharge rollers and stacked on the refeed tray.Type: GrantFiled: April 6, 1990Date of Patent: February 18, 1992Assignee: Ricoh Company, Ltd.Inventor: Shoji Hayashi

Patent number: 4785455Abstract: A light emitting device is disclosed which includes a semiconductor block, an active layer disposed in such a fashion as to penetrate through the mutually facing end surfaces of the semiconductor block, and an electrode disposed on the main plane of the semiconductor block, wherein the electrode consists of a first electrode portion disposed along the active layer, and a second electrode portion continuing integrally the first electrode portion and having the periphery thereof out of contact from the periphery of the second main plane of the semiconductor block. A current is caused to uniformly flow through the entire active layer, and a light emitting operation is carried out stably. Since the electrode is not disposed on the periphery of the semiconductor block, the occurrence of junction short-curcuit, which might otherwise occur when a wafer is cut off to produce laser chips or when the corners of the chip break off, can be reduced.Type: GrantFiled: July 27, 1987Date of Patent: November 15, 1988Assignee: Hitachi, Ltd.Inventors: Masaaki Sawai, Masamichi Kobayashi, Shoji Hayashi, Hiroshi Naka, Masahiro Ichiki
