Inventor: ROORANTO SHIYUMITSUTO
IPC: H04N5/59
Filed: 1988-06-21
Abstract: PURPOSE: To make the luminance distribution on a screen uniform by performing control by adding a correction voltage to a luminance scanning voltage according to the thickness of the front disk of the cathode-ray tube when the front disk varies in thickness horizontally and vertically. CONSTITUTION: The front disk 2 on a screen surface varies in thickness in an (x)-axial and a (y)-axial direction and increases in thickness toward the periphery. The transmissivity of the glass is proportional to the thickness, so a voltage which produces a correction electric field 1 shown in a figure 1 is added to the luminance scanning voltage to obtain uniform luminance. Correction voltages which are proportional to the thickness along the horizontal line and vertical line passing the center of the disk 2 are generated first by 1st and 2nd function generators 5 and 9. Those voltages are added 6 and applied to a cathode 11 in synchronism with the horizontal and vertical scans of a video signal from an amplifier 14 which is applied to a grid 13. Consequently, the luminance can be held uniform.

Title: Immersion tube for rh degassing apparatus
Inventor: KAWAMOTO EIJI
IPC: C21C7/10
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To quantitatively grasp the change of damage of an immersion tube by embedding many thermocouples in the vertically and mutually faced positions in the peripheral direction of an iron core of the immersion tube for RH degassing and measuring the temp. at each position. SOLUTION: In the RH degassing apparatus used to vacuum refining, etc., of a steel, the sheath thermocouples for temp. measuring are embedded in the vertically and mutually faced eight or more of positions 4 in the peripheral direction at the center part and the lower part of the iron core part 3 of the immersion tube to measure the temp. at each position 4. As the position of the thermocouples, the thermocouples are desirable to arrange at the positions of two steps at the center part and the lower part where the temps. of the immersion tube are very different, and at the position where unexpected spalling, etc., happens, and at four mutually faced positions in each 90 deg. angle in the peripheral direction.  By this arrangement, such danger work that the worker checks the inner part from the lower part of the immersion tube, is eliminated in each heat and the limit of durability of the immersion tube can quantitatively be checked. For example, since an inside brick becomes <=50mm the remaining size thereof when an iron shell temp. becomes >=1100 deg.C, it is judged that the immersion tube reaches the limited using temp. reference when the measured temp. becomes >=1100 deg.C.

Title: Decoding system
Inventor: SAKURAGI TOSHIO
IPC: H03M13/00
Filed: 1985-07-10
Abstract: PURPOSE:To attain sufficiently the correcting capability without changing a conventional correction code by using an error detection section of a signal demodulation section to detect error position information and using the error position information. CONSTITUTION:A PCM data recorded on a magnetic tape 1 is converted electromagnetically by a head 2 and a reproducing amplifier 3 and inputted serially to a demodulation section 4. A modulation data inputted to the demodulation section 4 is demodulated into an 8-bit parallel data and recorded in a RAM section 5. A data of the RAM section 5 is decoded by a correction code and extracted as a sound signal via a D/A conversion section 6 and a low pass filter 7. Difference from a conventional system resides in that error location is detected by the demodulation section 4 and a decoding circuit section 8 applies decoding by using a C1 code for the information. The demodulation section 4 includes the error detection section, which detects the presence or absence of an error, and if error exists, a pointer is outputted and stored in a RAM by using the RAM address at that time and the address having the pointer is the error location.
