Abstract: PURPOSE: To increase operation speed and to relax restrictions on the capacity of a dictionary by providing a compressor and a restorer with the dictionary of code words, corresponding to strings of single characters for compressing and restoring strings of single characters without accessing the dictionary. CONSTITUTION: In a compression mode, a port A interface 14 sends characters from a line 26 to a DC machine 12 through a data route 20 and a port B interface 16. The machine 12 uses a dictionary 22c beforehand to store code words corresponding to strings of single characters in the interface 16. Consequently, characters are converted into code words and are outputted from the interface 16 to a line 28. In a restoration mode, code words inputted to the interface 16 are inputted to the machine 12 and are converted into characters and are outputted to the line 26 through interfaces 16 and 14. Thus, compression and restoration are performed without accessing the dictionary to increase the operation speed.

IPC: H01J31/12
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To avoid the generation of a moire phenomenon on a screen by having a transparent surface of a fixed ratio for a basic pattern along an axis parallel to the overall direction of cathodes, regardless of the position of this axis in the right-angled direction. SOLUTION: A basic pattern is formed of picture elements 25 in this case. The transparency of the picture elements 25 is constant from the end to end of the picture elements 25 in the direction of grid lines 17 by the pattern of cathode conductors 13 and the grid lines 17. That is, each picture element 25 includes an opaque surface of the same ratio along an axis parallel to the overall aligned direction of the cathode conductors 13, regradless of the position of this axis in the right-angled direction (that is, in the direction of the grid lines 17). A grid 3 includes linear sections 23, but these linear sections 23 are right-angled to anode strips so as not to be a hindrance to moire effect. A more phenomenon is therefore invisible from an observer regardless of the position of the observer to the cathode surface.

Title: Signal processing circuit for magnetic recording and reproducing
Inventor: SHIROGANE TATSUO
IPC: H04N9/83
Filed: 1987-12-21
Abstract: PURPOSE:To eliminate the increase of hardware and to economize expense by providing a recording equalizer at the output side of a digital analog converter. CONSTITUTION:A digital video signal for a recording is converted into an analog video signal for the recording at a digital-analog converter 15, adjusted its frequency characteristics by a recording equalizer 20, and supplied to an interpolation filter 16. Since the characteristics of the recording equalizer are flat for the band of a low band converting chrominance signal, no harmful influence is given to the chrominance signal even when an equalizer filter action is executed for the video signal for the recording. Thus, since the recording equalizer with an analog circuit is enough, and the recording equalizer is not necessary to be digitized, the circuit scale of a digital signal processing part is never increased.
