Patent number: 10207884Abstract: An image forming apparatus, including a reference guide, an oblique conveyer roller, and a curve guide, is provided. The reference guide is arranged on one side in a widthwise direction with respect to a widthwise center in a sheet conveyer path and regulates a widthwise position of the sheet. The oblique conveyer roller applies a conveying force acting in a direction toward downstream along a conveying direction and toward the reference guide to the sheet. The curve guide is arranged upstream with respect to the oblique conveyer roller along the conveying direction and forms a curve. The curve guide includes an inner guide and an outer guide. The outer guide has a constant curvature throughout a width regardless of a widthwise position therein. The inner guide has a protrusive portion protruding toward the outer guide at a position on the other side in the widthwise direction with respect to the widthwise center.Type: GrantFiled: February 2, 2018Date of Patent: February 19, 2019Assignee: Brother Kogyo Kabushiki KaishaInventors: Kazuya Kamikawa, Shoichiro Nishimura

Patent number: 8294828Abstract: A television apparatus 100 is so designed as to store into ROM 14 the table that contains image control parameters and tone control parameters used for approximating the image and tone characteristics from different manufacturers wherein a microcomputer 13 reads and uses the image control parameters and the tone control parameters from the ROM 14 to thereby issue a signal processing instruction to a video processing circuit 11 and an audio processing circuit 12 in order to approximate the image and tone of each manufacturer. This allows collective control of image and tone and also allows a user to select collectively controlled image and tone easily.Type: GrantFiled: September 14, 2007Date of Patent: October 23, 2012Assignee: Funai Electric Co., Ltd.Inventor: Shoichiro Nishimura

Patent number: 7468875Abstract: A microcomputer 60 takes in voltages output from the sustaining voltage Vsus generation circuit 52, the addressing voltage Vadd generation circuit 53, and the standby voltage generating circuit 54 via A/D input ports 1 through 6 mounted on the microcomputer board, and performs examinations to judge whether abnormal values are detected about the voltages. If there is at least one abnormal value detected, the main power supply is set OFF and after a predetermined time the main power supply is set ON again to perform a reexamination. If the number of times when abnormal values about a certain voltage are detected reaches the number of abnormal value detections N, the main power supply is left OFF. The number of abnormal value detections N for the Vsamp, the Vset, the Ve or the Vscan, is set larger than the number of abnormal value detections set for the Vsus or the Vadd.Type: GrantFiled: December 21, 2006Date of Patent: December 23, 2008Assignee: Funai Electric Co., Ltd.Inventor: Shoichiro Nishimura

Patent number: 4911521Abstract: A connecting box for multi-optical fiber cables includes a plurality of container trays each adapted to contain surplus lengths of end portions of optical fibers, the plurality of trays being stacked one upon another. Each of the trays has a pair of receptive guide portions provided respectively at its opposite ends adjacent to one of the lateral sides of the trays so that each of the receptive guide portions can receive the optical fiber. Each tray is hingedly connected to each adjacent tray at the one lateral side thereof in a releasable manner. Each tray is pivotally movable with respect to each adjacent tray about an axis extending in the direction of said one lateral side. With this construction, the portions of the optical fibers extending outwardly from each receptive guide portion are not subjected to slack even when adjacent trays are pivotally moved away from and toward each other.Type: GrantFiled: February 8, 1989Date of Patent: March 27, 1990Assignees: Sumitomo Electric Industries, Ltd., The Kansai Electric Power Co., Ltd.Inventors: Masahiro Ryuto, Shoichiro Nishimura
