Title: Method for controlling character code for character broadcasting and signal processing circuit
Inventor: AMASHIRO JIYUNYA
IPC: H04N7/03
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a character display procedure capable of reducing memory capacity and attaining smooth scrolling without increasing the memory capacity. SOLUTION: In the case of outputting a displaying character code, the data of a 2nd character are read out by the timing of a 1st character of each line to determine and output the character code of the 1st character and the character code of a final character is determined from the data of a character just before the final character and outputted at the timing of the final character.  In the case of a closed caption, its signal processing circuit is constituted of a comparator 1 for comparing data from a memory with a blanking code (20h) and a transparent code (00h), a 1st switch 3a for selecting the transparent or blanking code in accordance with outputs (EQU, EQUA) from the comparator 1 and a 2nd switch 3d for outputting the code selected by the 1st switch 3a at the timing of 1st and 34th characters and outputting and transmitting read data at the output timing of the 2nd to 33th characters. Since the memory capacity for the 1st and the last characters of each line can be omitted, the memory capacity can be made to be just 512 bytes even when the capacity equivalent to one line is added for the purpose of making scrolling smooth.

The steel strip 1 after electrolytic cleaning is rinsed and dried and the SiO2 deposition thereof is measured by a measuring instrument 5 prior to coiling 10. The average deposition in the longitudinal direction thereof is determined. The current quantity is so determined by an arithmetic unit 6 from the line speed actually measured with a bridle roll 9 and the SiO2 deposition that the SiO2 deposition attains 1.0-3.0mg/m<2>. The electrolytic cleaning of the steel strip 1 is thus executed at the electrolytic current controlled by an current quantity control device 7. The line speed is decreased to obtain the desired SiO2 deposition when the determined current quantity value exceeds the equipment capacity.

Filed: 1984-04-17
Abstract: PURPOSE:To obtain a reproduced image having high S/N and high definition, by adding signals having bi-directional overshoot and preshoot to video signals and making recording when the level of the video signals changes. CONSTITUTION:Differentiation circuits 10 and 11 at the recording side differentiate inputted signals and a non-linear circuit 14 non-linearly changes the amlification degree of the inputted signals in accordance with their signal levels. Moreover, differentiation circuits 30 and 31 at the reproducing side differentiate inputted signals and a non-linear circuit 34 lowers the high-frequency component of video signals and, when the level of the video signals is low, performs de- emphasis operations, such as enlarging the degree of attenuation of the high- frequency component, etc. Since overshoot and preshoot are added to thus reproduced video signals before recording, reproduced videos having high S/N and definition can be obtained even after the noise component is cut off.
