Title: Controlling system for winder
Inventor: SAITOU RIYOUHEI
IPC: B65H23/198
Filed: 1982-11-17
Abstract: PURPOSE:To smooth starting and acceleration on the way of the increase in the diameter of a long slender material wound by a winder, by providing the winder with a speed setting unit and a tachometer generator for detecting the speed of the long slender material and by using the speed signals of the generator and a winding motor to control the motor. CONSTITUTION:As a wire 1 is wound around a winding roll 21, the speed of an electric motor 22 is reduced depending on the speed signals of the motor and the wire and the position signal of a dancer roll 2. A winder 20 is stopped when a certain quantity of the wire 1 is wound around the winding roll 21. When the winder 20 is started again with the certain quantity of the wire 1 wound around the roll 21, an instruction for the speed of the winding motor 22 remains set by a ratio setting unit 25, so that rapid winding is begun. However, the speed signal of the wire 1 is applied from a tachometer generator 6 to a controller 23 to drive the motor 22 at an appropriate speed under the action of the controller. Since the change in the position of the dancer roll 2 is proportional to the integrated value of the speed of the wire 1, the winder 20 stopped on the way of the winding of the wire can be easily started again without making an artificial compensation.

Title: Separating method of transfer paper
Inventor: SHIBATA KIYOSHI
IPC: G03G15/14
Filed: 1984-09-27
Abstract: PURPOSE:To eliminate defective transfer and to permit the simple and sure sepn. of transfer paper from a photosensitive drum by operating an electrostatic charging device for sepn. or executing electrostatic transfer and sepn. of the transfer paper in a stop state according to the tearing strength of the paper. CONSTITUTION: The development of an electrostatic latent image is executed while the operation of the electrostatic charging device for spn. is held stopped in case of the high tearing strength transfer paper. The formed toner image is electrostatically transferred to the transfer paper via an electrostatic charging device 15 for transfer. The transfer paper is separated from the drum to which the electrostatic attraction force by the device 15 acts no longer. The deficient electrostatic attraction force between the drum 3 and the transfer paper is thus prevented and the sure transfer is made possible by bringing the transfer paper into the sure and tight contact with the transfer part of the drum 3. The electrostatic transfer of the toner image, etc. are executed in the operating condition of the device 16 in case of the low tearing strength transfer paper. The electrostatic attraction force of the transfer paper after the transfer is annihilated by the device 16, by which the transfer paper is separated from the drum 3.

Abstract: PROBLEM TO BE SOLVED: To provide a buried target searching device, capable of exactly detecting a faint signal, excellent in discriminativeness, and capable of displaying a search image high in measurement accuracy. SOLUTION: Signal catching circuits 8, 8' sample received search-wave signals at predetermined constant time intervals, data acquired on a frame-by-frame basis by sampling from when the sampling is started till when the sampling is ended are intermittently transferred to a main control circuit 9 at high speed, and the main control circuit 9, when it receives the acquired data on a frame-by- frame basis from the signal catching circuits 8, 8', sends a sampling-resetting signal to the signal catching circuits 8, 8', whereby time is set up for starting sampling received search-wave signals for a next frame. Because processing by the main control circuit 9 can be synchronized with time for starting sampling by the signal catching circuits 8, 8' for every frame, a search wave can be exactly detected.
