Title: Winding process
Inventor: TERADA KEIZOU
IPC: B65H59/38
Filed: 1980-09-19
Abstract: PURPOSE: To regulate winding tension at a constant value irrespective of the positions of a ring rail of a ring twisting machine when thread yarns are wound by the latter, by correctingly controlling the rotational speed of a spindle, corresponding to the vertical mortion of the ring rail.  
     CONSTITUTION: A spindle speed adjusting device 1 generates a signal for setting the middle value of the spindle speeds at each winding rate. The position of a ring rail is detected by a petensiometer 2. The difference in the spindle speed between the position detected and the upper or lower position where the ring rail has been previously positioned is transformed into an electrical signal for disturbing the spindle speed. Signals generated from the spindle speed adjusting device 1 and a spindle speed changing device 3 are transmitted to a spindle speed control 4 for controlling the rotational speed of a variable speed motor 5 in response to the signals.

Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of S/N and to improve the quality of optical transmission by controlling the output of inserted optical signal to settle the output ratio of optical signal and inserted optical signal within a prescribed range when newly inserting the optical signal into a wavelength multiplex optical transmission system. SOLUTION: One part of input multiplex optical signal is branched by an optical branch 11, converted to an electric signal by an optic/electric converting circuit 12 and inputted to an output control part 17. On the other hand, one part of inserted optical signal from an optical transmission part 13 is branched by an optical branch 14, converted into an electric signal by a converting circuit 16 and inputted to the control part 17 and at the same time, the remaining optical signals are inserted while multiplexing wavelengths with the optical signals by a photocoupler 15. The control part 17 detects the output electric signals from the converting circuits 12 and 16 and controls them so as to fix the ratio of outputs.  At such a time, the ratio is adjusted so that the output power of optical signals to be inserted can be equal with the optical signals of respective wavelengths on a transmission line. Thus, the output power of inserted optical signals can be made equal with the optical signals of respective wavelengths on the transmission line in spite of a loss on the transmission line.

Title: Heat fixing device
Inventor: ANZAI MASAYASU
IPC: G03G15/20
Filed: 1977-11-07
Abstract: PURPOSE: To obviate the occurrence of fixing defect and prevent contamination and waste of paper by reducing the running speed of recording paper at the time when the final end part of the continuous recording paper passes the heat plate.  
     CONSTITUTION: While recording paper is passing, it is detected with the paper detecting element 8 provided before a brake suction means 7. When the final end part is detected by the paper detector 8, the signal thereof causes the number of revolutions of a motor 6 to be decreased by way of an amplifier 9 and driver 10. The reduction in speed also varies with the temperature and size of a heat plate 2 and the temperature of a heat roller 3, and the speed about 1/2 the normal speed is sufficient. As a result, the paper speed is decreased, and therefore the quantity of heat allowing for the decrease in the adhesiveness to the heat plate 2 is applied by the heat plate 2 and heat roller 3, whereby perfect fixing is done. Thereby, the occurrence of fixing defect is obviated and contamination and waste of paper may be prevented.

Abstract: PURPOSE:To apply an adhesive agent without deviating the position of a disk when applying the adhesive agent to the disk while using a roll coater by respectively setting the surface coarseness and surface roudness of a tray lower than specified values. CONSTITUTION:For a tray 6 for carrying a single optical disk, the surface coarseness is set lower than Rmax1.0S and the surface roundness is set lower than 3mumWcm. A disk 5 on a tray 1 is fed into a roll 10 for applying the adhesive agent by driving a carrier conveyer 9, and the hot melt adhesive agent is applied to an information recording film. In this case, since the disk 5 is pressed to the tray 6 by the roll 10 and adhesively pressurized to the tray 6, air between the disk 5 and the tray 6 is further excluded and the position of the disk 5 is further strongly held. By this operation, the position of the disk 5 is not fluctuated even when an operation is generated to roll up the disk 5 in the tangential direction of the roll 10 by the roll 10.
