Title: Image display device
Inventor: INOUE AKIRA
IPC: H01J31/12
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To improve heat radiation efficiency from a cathode substrate by providing a black surface treating film on at least one of a surface of a back container side and an inner surface of back substrate of the cathode substrate. SOLUTION: When a suitable negative voltage is applied to a cathode 31 and a desired positive voltage is applied to a gate electrode 34, electrons are discharged. Discharged electrons are focused by an electrostatic lens effect of a through hole 7a of a focusing electrode 7, and are accelerated by a high voltage applied to a metal backing layer provided on a fluorescent surface 2. The accelerated electrons collide with phosphor dots of the fluorescent surface 2 with high energy to emit light, and reproduce an image on the fluorescent surface 2.  Since heat generated by a cathode board 6 is radiated to the outside of a device by from black surface treating films 11, 12, an image of high quality is reproduced controlling a color shift, etc., by thermal expansion of the cathode board 6, and the cathode board 6 and a sealing part 5 are prevented from being damaged by the thermal expansion. Moreover, since the cathode plate 6 is pinched between a front glass container 1 and a back container 3, deformation is not caused easily, and the image of high quality is reproduced.

Abstract: PURPOSE:To enable the reading of a tilted character line, by shifting the next imcomplete line by a line within a buffer memory and prior to the scan of the next line and then performing the next scan after feeding a slip in response to the extent of the above-mentioned shifted extent of the line. CONSTITUTION:When a complete character line A1 is first detected, the centers Y12 and Y22 of the Y coordinates are obtained at two black picture element line regions M12 and M22 of the line A1. Then the difference Y2 is obtained between the centers Y12 and Y22, and the value and the polarity of the difference Y2 are decided the degree of inclination in the scanning direction X of the desired line A1 and as the direction of inclination respectively. Both the degree of inclination and the direction of inclination obtained with the line A1 are regarded equal for character lines A2 and A3 in terms of an ordinary slip. Thereafer, both the Y2 and the polarity are preserved for the separation between a desired line and the next line. Then the desired line A1 is read out of a 1-line buffer memrory 2 and fed to a character recognizing system via a procedure which standardizes the character pattern information parallel to the X axis after a compensation of the degree of inclination.

The voltages are overlapped on the driving signals, and fluctuations are generated in the voltages. The output fluctuation signals are inputted to rectifier circuits 13a and 13b for individually rectifying the signals, and the results are outputted. Even if the phase deviation has occurred between each of the ultrasonic-wave sensors at this time, only the positive voltages appear in the output voltages of the rectifier circuits. The signals are synthesized into one signal. Therefore, the output signal becomes large. The signal is inputted to an amplifier circuit 4. After the amplification, the signal is inputted to a detecting circuit 5, and the fluctuation is detected.
