Title: Photomagnetic reproducer
Inventor: KIMOTO KIYOSHI
IPC: G11B11/105
Filed: 1984-04-18
Abstract: PURPOSE:To always keep an optimum state and to maintain the high performance for a long period of time for a photomagnetic reproducer, by controlling the amplitude levels and the delay times of two input signals to a differential amplfier so that a pilot frequency signal contained in a differential amplification signal is minimized. CONSTITUTION:The outputs of photoelectric converting means 19 and 20 which gave the photoelectric conversion to two reproduced beams obtained from an optical system 18 contain reproduction signals S1 and S2 and noise components n1 and n2. The gain of a variable gain amplifier 24 is controlled to minimize the amplitude difference between both components n1 and n2. Thus a differential output Sd is obtained from a differential amplifier 25. The laser output of a semiconductor laser 14 is superposed after modulation of amplitude onto noise component n3 and n4 produced by the defective control of amplitude and phase by means of a pilot frequency signal. The laser output is extracted through BPF27 and 26, and an output corresponding to the amplitude difference is extracted by an amplitude comparator 37. Then the amplification factor of the amplifier 24 is controlled to minimize the output of a comparator 33. Thus the signal levels of components n1 and n2 supplied to the amplifier 25 are balanced automatically to eliminate the noise components.

Title: Method for controlling loop of material to be picked in pickling tank
Inventor: MATSUNAGA MASAO
IPC: B21B39/00
Filed: 1989-03-31
Abstract: PURPOSE:To fix the height of the loop of a material to be pickled in a pickling tank by comparing the command value of the preset optimum length of the material in the tank with the length of the material in the tank and controlling the speed of the inlet side bridle roll so that the length of the material is held at the command value. CONSTITUTION:The inlet-side bridle roll 11 or the outlet-side bridle roll 14 is independently operated, and the length of the material to be pickled in a pickling tank 1 is obtained by pulse generators 24 and 27. The operation is continued until the length is controlled to the command value of the material length, and the length is held at the command value, namely the optimum material length in the pickling tank, in the subsequent normal running. The material length is always compared with the command value, and the speed of the bridle roll 11 is controlled so that the length is held at the command value. As a result, the optimum loop height can be maintained regardless of the quality, thickness, width, etc., of the material 9 to be pickled. The symbol 13b in the figure shows an inlet-side speed command computing element.
