Title: Index signal detector for floppy disk driving part
Inventor: UNO JUICHI
IPC: G11B27/10
Filed: 1991-03-29
Abstract: PURPOSE:To facilitate the assembling work of a floppy disk driving part by adjusting the deviation of the starting position of a floppy disk with the fixed position of an index trigger signal detector with the selection of the variable reference value of a comparator. CONSTITUTION:The index trigger signal detector 20 is fixed in a position selected in the vicinity of the outer periphery of the rotor of a spindle motor. An index trigger signal IDT as the output of the detector 20 is supplied to the starting input of a counter 22, the counter 22 is started to operate counting after the index trigger signal is applied. Then, the counted value is compared with the prescribed variable reference value in the comparator 23. Since the comparator is constituted of a delay circuit substantially, an index signal ID is outputted from an output terminal 24 after the lapse of desired delay time from the time of detecting the index trigger signal. Thus, by adjusting the variable reference value, the assembling work is facilitated.

IPC: B21B37/48
Filed: 1985-03-30
Abstract: PURPOSE:To detect exactly only the tension acting on a rolling material and to execute control with high accuracy by excluding by correction, the consumed current-component of a driving motor by the temp. change of the rolling material from the actual current value flowing in the driving motor. CONSTITUTION:The deformation resistance value at the measured temp. is read from a temp.-deformation resistance value diagram when the temp. value is momentarily measured by a thermometer T. The current consumption of the motor M with respect to the resistance value is calculated by a control device form said value. On the other hand, the actual current value flowing in the driving motor M is measured by an ammeter F and this value and the current value calculated from the change of the deformation resistance value by the temp. change are compared and only the change of the motor M current by the tension acting on the rolling material is extracted. More specifically, the change of the current flowing in the motor m which acts on the rolling material A between a planetary type cross helical rolling mill R and mill E is calculated by subtracting the consumed current-component by the temp. change of the rolling material form the current value flowing actually in the motor and said current is so controlled as to be kept constant, by which the tension acting on the material A is made constant.

Title: Method and device for image formation
Inventor: SHOJI HISAFUMI
IPC: G03G13/01
Filed: 1985-03-29
Abstract: PURPOSE:To obtain recording images of invariably high picture quality by driving and rotating a transfer means unless the transfer means contacts an image formation body. CONSTITUTION:A transfer roller 50 contacts the image formation body 1 after a toner image of the 3rd color passes through a transfer position. Further, the transfer roller 50 rotates by itself in a noncontacting state and is driven to rotate by contacting the image formation body 1, so a blade which is pressed against the surface of the roller 50 at any time cleans the transfer roller 50 all the time, so that the contamination of the back surface of a transfer material due to the sticking of toner on the transfer roller 50 is prevented. The transfer roller 50 contacts the image formation body 1 with constant pressure, so toner is easy to leave the surface and a uniform and sufficiently large electric field is easily generated at a transfer part.

Abstract: PROBLEM TO BE SOLVED: To provide a variable grain amplifier that assures wide gain variable width against a high speed image signal and can realize a gain setting curve inversely proportional to the setting value which can be set at an optimum value without the need for unnecessary arithmetic operations from read image data.
