Title: Video signal waveform equalizer
Inventor: NAKAMURA KAZUHIRO
IPC: H04N5/21
Filed: 1990-03-30
Abstract: PURPOSE:To improve the picture quality by inserting information being reference of waveform equalization as to a chrominance signal into a video signal. CONSTITUTION:A low frequency chrominance signal is converted into an original frequency band (high frequency) in the inside of a VTR 306 in the reproduction mode and an FM luminance signal is FM-demodulated. Then a color signal and a luminance signal are synthesized to generate a base band video signal. The base band video signal is inputted to a waveform equalizer 303 via a selector switch 302, in which waveform distortion is eliminated in the VTR system. The base band video signal from which waveform distortion is eliminated is inputted to a decoder 304, in which a prescribed signal processing is implemented and the result is inputted to a color picture tube 305. Thus, even when there is a difference as to the signal distortion between the luminance signal processing system and the color signal processing system as a VTR resulting from the processing of the signal in a tentatively different path, the fact is compensated and the picture quality is improved.

Title: Production of thermal head
IPC: B41J2/335
Filed: 1992-04-03
Abstract: PURPOSE:To provide a thermal head, in which a heating value of a center part of a heating resistor is lower than that of each end thereof in a sub- scanning direction, without providing a troublesome production process. CONSTITUTION:After a strip-form heating resistor 2 is formed on an insulating substrate 1, the center part of the heating resistor 2 in a sub-scanning direction Y is irradiated with a laser beam of a power sufficient for lowering the resistance value thereof. Alternatively, after a plurality of heating resistors 2 are formed on an insulating substrate 1, each end of the heating resistor 2 in a sub-scanning direction Y is irradiated with a laser beam of a power sufficient for lowering the resistance value thereof without scattering the heating resistor 2. When an area to be irradiated with the laser beam in a main scanning direction is the full area of the heating resistors 2 in a main scanning direction, an obtained effect can be similar to that when the width of the heating resistor in a sub-scanning direction is reduced to be smaller than that of one pixel in a main scanning direction.

Filed: 1985-04-19
Abstract: PURPOSE:To prevent generation of thermal stress regardless of a difference in a coefficient of thermal expansion by forming radial pressure means for one bearing in the same direction of radial pre-pressure means for the other bearing in such a manner as to press the other bearing. CONSTITUTION:A radial pre-pressure mechanism 24 for pressing an upper bearing 13 in the radial direction and a guide mechanism 25 capable of guiding the bearing 13 in the radial direction are disposed between the upper bearing 13 and the base 15. The radial pressure mechanism 24 is adapted to press the bearing 13 in the same direction as a radial pre-pressure mechanism 17, because if the pressing direction of the mechanism 24 is different from the pressing direction of the radial pre-pressure mechanism 17, there is the possibility that a rotary shaft 12 is inclined. Accordingly, even if thermal expansion is caused in the base 15 and the bearings 13, 14 by generation of heat of a motor or the like, thermal expansion of the base and the bearing 13 is absorbed by a compression coiled spring 24a of the radial pre-pressure mechanism 24.
