Title: Heating device
Inventor: WATANABE TOSHIO
IPC: F16C13/00
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To obtain a device where a fixed image is not soiled by toner by constituting the surface area of a driving roller with the maximum image forming feasible width of recording material passing through a fixing nip of material whose releasing property with respect to image forming material is inferior in comparison with the other surface area. SOLUTION: The surface area of the driving roller corresponding to the image forming feasible maximum width of the width of the recording material passing through the fixing nip is constituted of the material whose releasing property with respect to the image forming material is inferior in comparison with the other surface area of the driving roller corresponding to the width of the recording material. When a recording material sheet is separated from film 2 in the fixing nip in this heating device, a slight amount of toner remains sometimes on the film 2 and moves toward the driving roller 5 in a state where it is still stuck to the film 2.  However, the surface of the image forming width of the driving roller 5 is inferior in terms of the releasing property to the film 2 constituted of polyimide and coated with fluorine, for example, so that the toner is stuck to the polyimide side when it comes in contact with the surface of the driving roller 5.

Title: Standby line monitor system for transmitter
Inventor: TAKAGI KAZUTO
IPC: H04L69/40
Filed: 1992-05-22
Abstract: PURPOSE:To allow a transmitter provided with one standby line with respect to plural active lines to surely confirm it that a signal via the standby line is sent accurately and to allow only one station to confirm it. CONSTITUTION:A changeover means 1 selects any of active lines and a signal flowing to the selected active line is sent to a standby line. Furthermore, an identification code transmission means 2 sends an identification code of the active line selected by the changeover means 1 to the standby line. On the other hand, an identification code extract means 3 at a receiver side extracts an identification code sent from the identification code transmission means 2. Then a comparator means 4 compares a signal sent through the active line with the identification code extracted by the identification code extract means 3 added thereto with the signal sent through the standby line via the changeover means 1. As a result of comparison, when the signals are identical, it is discriminated that there is no hindrance even after the changeover from the selected active line into the standby line.

Title: Stop-controlling apparatus of loom
Inventor: ONO MITSUTOSHI
IPC: D03D51/18
Filed: 1990-05-23
Abstract: PURPOSE:To prevent the grave accident during unmanned operation period as far as possible by programming in such a manner as to measure the gray cloth length of a loom and stopping the operation of the loom when the length reaches a unit woven length within a prescribed period. CONSTITUTION:Each loom furnished with a controlling apparatus is connected to a host computer acting as a centralized control apparatus. The time to get a unit woven length of each loom and the time to weave a cut mark in an unmanned operation period such as nighttime are preparatorily calculated by the computer and, when the estimated time falls within a range after the lapse of a half of the unmanned operation period, the loom is stopped at an interval closest to the unmanned operation period. When the interval falls after the lapse of a half of the unmanned operation period and the unmanned operation of the loom is expected to be prolonged, the operation of the loom is stopped at an interval immediately before the unmanned operation period. Since the loom is stopped always at the interval, there is no adverse effect to the quality of the woven cloth.

Title: Safety circuit for balancing cargo handling gear
Inventor: TOMARU HITOSHI
IPC: B66F19/00
Filed: 1988-05-31
Abstract: PURPOSE:To keep off any malfunction at the time of load sudden change by installing a safety circuit in a balancing cargo handling gear through which an operator adds his hand to a work directly for its lifting with light force, and making the threshold value of a load differential signal so as to become larger if the work grows heavier. CONSTITUTION:A safety circuit 15 inputs a load differential signal FL', differentiating a load signal FL out of a force detector 6 and a speed signal theta', and it outputs such a command as stopping balancing operation when the absolute value ¦FL'¦ of the load differential signal FL' is larger than a threshold value epsilonFL', and the absolute value ¦theta'¦ of this speed signal theta' is larger than the threshold value epsilonFL' as well. In addition, the safety circuit 15 is made so as to enlarge the threshold value epsilonFL' of the load differential signal FL' in proportion to a memory load value W0. If this safety circuit is set up, the balancing operation is suspendible at the time of load sudden change. Moreover, if weight of a work 7 becomes larger, the threshold value epsilonFL' of the load differential signal FL' becomes larger as well, so that even if the work 7 becomes heavier, the load sudden change is accuratelt judged, thus there is no malfunction at all.
