Title: Printer and cartridge
Inventor: SARUTA TOSHIHISA
IPC: B41J29/20
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a printer, and an ink cartridge for use therein, in which data of the residual quantity of ink, and the like, can be rewritten surely even a memory element having a small number of rewritable times is mounted on an ink cartridge. SOLUTION: In the printer 1, a sequential access type EEPROM having a small number of rewritable times is employed as a memory element 80 mounted on an ink cartridge 107K, 107F. Print controller 40 of the printer 1 also comprises a memory for storing data concerning to the ink cartridge and data of the residual quantity of ink, and the like, is stored in both memories. An EEPROM or a DRAM may be employed as the memory on the printer 1 side. Data is written in the memory element 80 every time when the residual quantity of ink is calculated and written in the memory cell 81 of the memory element 80 only when a power down instruction is delivered. Since writing frequency of the memory element 80 is decreased as compared with the memory element 80, reliability of data is enhanced while limiting the number of rewritable times.

Title: Video signal correcting device for video camera
Inventor: SHIMIZU TOSHIO
IPC: H04N5/217
Filed: 1988-12-29
Abstract: PURPOSE:To easily suppress a noise signal even when a dark place is photographed by setting pedestal control to a 'zero' level and switching gamma correction operation to an OFF state when the level of an AGC signal is >=a prescribed level. CONSTITUTION:Since the video signal with an extremely small level is outputted from a sample-hold circuit 5 when the dark scene is photographed, the large AGC signal is generated in an amplifier circuit 7 and an amplification factor is improved. Then, the video signal is amplified by the increased amplification factor and added to a pedestal control circuit 9. Thus, the pedestal level to be inserted to the video signal is set to the 'zero' level in the pedestal control circuit 9 and the video signal is outputted to a gamma correcting circuit 13 in a condition that the level of the video signal is wholly lowered. In the gamma correcting circuit 13, the gamma correction operation is turned to the OFF state and the video signal is outputted to a process processing circuit 15 without the gamma correction. Accordingly, the signal component of the low level, namely, the output of a noise component is suppressed.
