Title: Rolled paper feeding device
Inventor: NISHIYAMA KOJI
IPC: G03G15/00
Filed: 1985-10-07
Abstract: PURPOSE:To enable decrease of the inertia load of a paper in roll, by a method wherein a clutch is provided for transmitting a rotation force only in the conveying direction of a paper, and an inertia rotation time during the stop of a driving means is increased over a time of a stop forced by a brake means. CONSTITUTION:When a paper from a paper feed roller 2 is cut by means of a cutter 3, a paper feed roller 2 and a paper 1 in roll start to reduce a speed. However, since a reduction time t2 of the paper 1 in roll by a brake 6 and a time t1, in which the paper feed roller 2 is stopped by a one-way clutch 13 during the stop of a driving motor 12 as the roller is rotated by inertia, are set to a relation of t1>=t2, the paper between the paper 1 in roll and the roller 2 is stopped in a tension state. Thereafter, since the paper feed roller 2 starts rotation such that a rotation speed is gently increased, the paper 1 in roll is also rotated gently. This enables starting of the paper in roll without the occurrence of a slip due to the inertia load of the paper in roll.

Title: Transmission switch system
Inventor: TAKAHASHI YASUSHI
IPC: H04B10/079
Filed: 1984-10-24
Abstract: PURPOSE:To suppress effectively the increase in modal noise scarcely discriminated at on-line repair and test by discriminating it as the increase in the modal noise of the repeater layer of pre-stage when an error takes place without reduction in an input level, transmitting information on the pre-stage not only with normal switching but also applying feedback to the laser state. CONSTITUTION:If a optical input level is decreased due to a fault of a repeater 1 or a transmission line 2, a signal is generated from a detector 6, and fed to a switch controller 8, and the line is switched to a spare line. While a modal noise increases, a signal is not supplied from the detector 6, and the signal is fed from the switch controller 8 from an error detector 7 only. In such a case, the line is switched to the spare line, a signal flows to the faulty line, a control signal is fed from the switch controller 8 to the faulty repeater 1 to control the state of laser thereby reducing the modal noise.
