Abstract: PURPOSE:To efficiently deposit the heavy metals in a concd. waste strong basic ferric chloride liquid contg. iron and Ni and the other heavy metals by rotating and stirring said waste liquid and lumped metal iron in a rotating vessel and discharging the generated excess liquid to the outside. CONSTITUTION:The waste liquid contg. the iron and heavy metals except the iron generated at the time of etching a metallic sheet (consisting of steel, stainless steel, Ni alloy, etc.) with the concd. strong basic ferric chloride liquid and particularly Ni at the highest ratio is heated to about 60-120 deg.C and is housed together with the lumped metal iron into a cylindrical vessel body 1. An electric motor 9 is then driven to rotate revolving shafts 2, 2' by means of a chain 13, by which the vessel body 1 is turned and the iron lumps are brought into contact with each other to strip the Ni sticking to the iron lump surfaces. The heavy metals except the iron are thus deposited by utilizing the ionization tendency. The gaseous hydrogen, foam and mists generated in this stage are discharged from branch pipes 15, 15' through a discharge passage 14 provided in the shafts 2, 2'. The heavy metals except the iron are thereby efficiently deposited from the waste ferric chloride liquid and the waste liquid is recycled by regeneration.

Title: Magnetism generator and convergence correcting device and magnetizing method of magnet ring
Inventor: ITO HIROSHI
IPC: H01J29/54
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To easily adjust central convergence even in a cathode-ray tube on which opening between beams is little, and obviate a change in an installing position even to a beam interval-dispersed CRT and a change to adjusting magnet rings different in a magnetization quantity by performing unbalanced magnetization to arrange a difference in a magnetization quantity between an N pole and an S pole of the magnet rings. SOLUTION: In a central convergence correcting device using unbalanced magnetization magnet rings, claws of two Y magnetization magnet rings are closed so as to overlap each other, and when a relative turning angle of the Y magnetization magnet rings is minimized, a balance of a magnetic field in the vicinity of zero is lost, and ambiguous magnetic force is made. Therefore, even if opening between R, G, B beams is about 0 to 0.5 mm from the center, opening of the claws of the two Y magnetization magnet rings can be adjusted in an easily operable range. When opening between the R, G, B beams in a cathode-ray tube is large, opening of the claws of the two Y magnetization magnet rings is set large, and can be made to cope with it.

Filed: 1988-06-17
Abstract: PURPOSE:To ensure the balancing state without being affected by the dispersion of the ON-resistance of an analog switch, the operating condition and the fluctuation of the ambient temperature by reducing the resistance of the analog switch. CONSTITUTION:A half power of a signal entered from a 4-wire line input terminal 1 and amplified by an amplifier 4 is outputted to an input/output terminal 3 of a 2-wire line. Moreover, the signal fed to the input/output terminal 3 is not transmitted to a resistor R2 but outputted to an output terminal 2 via a differential amplifier 5. Balanced circuit networks 13-16 are switched by an analog switch 12 corresponding to the impedance of the 2-wire line. The resistance of the analog switch 12 is selected smaller than the resistance of the balanced circuit network by using a GIC(Generalized Immitance Converter). Thus, the balanced state is always ensured without being affected by the dispersion in the ON-resistance of the analog switch 12, the operating condition of the resistance or the fluctuation due to ambient temperature.
