Title: Take-up device
Inventor: OGURA MITSURU
IPC: B65H23/198
Filed: 1989-10-06
Abstract: PURPOSE:To prevent a sheet from being excessively pulled and/or slackened while the donor sheet is in tension at all times by providing a torque limiter and an electromagnetic clutch between a winding shaft and a motor, and thereby providing a winding/rewinding control means which turns the electromagnetic clutch off when the sheet is winded. CONSTITUTION:The winding speed of a sheet at the time of winding is controlled by a speed control means 101 to be consistent with the speed at the circumference for the diameter formed when the whole of the sheet is winded up on a winding shaft 103. In addition, a winding/rewinding control means 100 has the rotation of a motor transmitted to the winding shaft 103 with electromagnetic clutch 105 turned on at the time of winding so that a torque limier 104 is thereby actuated. This thereby allows the sheet to be winded up while a specified torque is being applied with slips provided as required when the diameter formed by the sheet winded on the winding shaft 103 is small at an early stage of winding, even if the rotation speed of the motor 106 is excessively high. This thereby prevents the sheet from being damaged and/or slackened owing to excessive tension.

IPC: G01S7/52
Filed: 1989-10-11
Abstract: PURPOSE:To achieve highly accurate setting of delay time by providing a delay time circuit for generating delay time to be applied to each of a plurality of transmitter/receivers by a digital signal inputted into a variable length shift register to remove instability of the delay time of the delay circuit. CONSTITUTION:#1-#n variable length shift registers 13-1 to 13-n are arranged in the same number as that of #1-#n transmitters 3-1 to 3-n. A CPU 12 calculates delay time required by each transmitter 3-1 from a focus position to which beam is focused beforehand and divides the delay time by a cycle of a clock signal to determine the number of shift stages of the corresponding #1 variable length shift register 13-1. A selection data of the number of shift stages is set for the registers 13-1 to 13-n separately. Then, a digital pulse generator 11 supplies a digital pulse signal to the registers 13-1 to 13-n. Each of the registers 13-1 to 13-n output a signal delayed corresponding to the number of shift stages preset and the signals undergoes an analog conversion through corresponding #1-#n D/A converters 14-1 to 14-n to drive transmitters 3-1 to 3-n.

Title: Image forming device
Inventor: MATSUMOTO KENTARO
IPC: G03G15/08
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To achieve the precise control of toner concentration and improvement in image quality by controlling the toner concentration, based on the peak value of the output ripple of a magnetic permeability sensor. SOLUTION: The toner concentration is controlled, based on the top (peak value) of the output ripple of the magnetic permeability sensor 14. By using the peak value of the output ripple as control data in such a way, it does not drop below a reference value even if the level of developer in a developing device 5 becomes low due to a temporary toner concentration decrease, therefore toner is supplied from a toner bottle 16 and proper toner concentration is maintained. Where the number of the rotations of a carrying member 10 is (r), (rpm), the data of the magnetic permeability sensor 14 divided at regular intervals, equal to or longer than 60/r(sec), is the peak value of each interval, and it is preferable that an average value in a fixed period of time be used as the control data. Thus, the toner concentration can be controlled more precisely.

Abstract: PROBLEM TO BE SOLVED: To obtain a locating apparatus by which a distance can be computed more precisely by a method wherein a line-to-line current and voltage detection means which is installed at one end of a single-circuit transmission line is provided, and a computing means by which a distance up to a corrected short- circuit failure point is found by using a specific computing equation is provided. SOLUTION: When a failure detection part 16 detects a short-circuit failure point, a CPU finds a distance up to an uncorrected failure point on the basis of the sample value of a current and a voltage, immediately before the failure point, which are stored in a memory 15. When a distance (w) is smaller than a distance d1 up to a branch point, the distance (w) is adopted as it is as the distance up to the failure point, When the distance (w) is larger, a distance (y) is found by using a computing equation of y=[(w-d1)×1/×2]/[1-2r2×1 (w-d1)/×2R3] (where (w): uncorrected distance up to failure point from one end, d1: distance up to branch point from one end of transmission line, z1 and z2: line impedance z1=r1+j×1 and z2=r2+j×2, R3: line-to-line equivalent resistance of load capacitance in rear part of branch point and (y): corrected distance up to failure point from branch point). The distance d1 is added to the found distance (y) so as to obtain a distance.
