Title: Cathode-ray tube of magnetic focusing type
Inventor: GEMA TAKETOSHI
IPC: H01J29/64
Filed: 1981-05-21
Abstract: PURPOSE:To obtain a cathode-ray tube of a magnetic focusing type, wherein the cathode-ray tube provides excellent focusing characteristics and makes focus- adjusting possible. CONSTITUTION:A magnetic adjuster which is at least partially cylindrical, made of ferromagnetic material and composed of a plurality of magnetic field rectifying elements, is provided within a neck 30, the adjuster being located oppositely to a permanent magnet 31 arranged outside the neck 30 of a cathode-ray tube. The magnetic adjsuter comprises first, second and third magnetic field rectifying elements 32, 33 and 34; the magnetic field intensity becomes maximum between the first and second magnetic field rectifying elements 32 and 33, whereas two of the focusing lenses are formed in the peak position of both the magnetic fields equivalently. As the permanent magnet 31 moves, the magnetic field distribution changes; the magnetic field peak becomes greater as the center of the permanent magnet 31 approaches, whereas the peak is in turn reduced as the magnet 31 departs. Accordingly, the distance from the target can be made equivalently larger or smaller and thus focus-adjusting becomes possible.

Title: Nonlinear compensating circuit
Inventor: OGAWA HIROSHI
IPC: H03F3/68
Filed: 1988-03-31
Abstract: PURPOSE:To simplify the constitution of a nonlinear compensating circuit by forming this compensating circuit when the outputs of a distortion generation amplifier and a main amplifier are synthesized and then a linear circuit containing a main amplifier only when the distortion generating amplifier is turned off. CONSTITUTION:A switch 8 is turned on and the outputs of a distortion generating amplifier 4 and a main amplifier 4 are synthesized by a synthesizer 5 approximately in the opposite phases to each other. Thus the input/output characteristics opposite to those of an ordinary amplifier can be obtained. In other words, it is possible to obtain a nonlinear compensating circuit of a high frequency amplifier where the increment of the output electric power is increased with increase of the input electric power. While the switch 8 is turned off to stop the supply of power to the amplifier 3, therefore only the amplifier 4 outputs. Thus the output of only the amplifier 4 is sent to the output of the synthesizer 5 and a linear circuit is obtained. In such a way, the constitution of the nonlinear compensating circuit is simplified.
