IPC: B41J2/175
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To accurately monitor use degrees at every ink tank to give warning even when respective ink tanks are frequently attached, detached or replaced to enhance the reliability of printing operation by monitoring use degrees at every ink tank and outputting warning in case of exceeding the use limits of the respective ink tanks. SOLUTION: Ink emitting quantity calculated from the printing quantity designated from a CPU 11 to a printing head 21 is detected to store an ink use degree in an EEPROM 14 and use limits of three stages are preliminarily stored in the EEPROM 14 at every ink tank 30. When the use degree exceeds the use limits, warning is outputted by the CPU 11 and, on condition that warning is outputted, an ink tank number is stored and, when the ink tank 30 having an ink tank number same to the stored ink tank number is re-mounted, the printing using this ink tank is prohibited. By this constitution, the use of ink other than genuine ink is cerainly prevented.

Filed: 1989-12-13
Abstract: PURPOSE:To effectively prevent mold from being generated for a long time even if disinfection work is not execute by coating a bathroom curtain with a soluble glass having a mold-proof component. CONSTITUTION:A bathroom curtain 10 is divided into an upper layer 11, an intermediate layer 12, and a lower layer 13, in the horizontal direction, and the upper layer 11 and the lower layer 13 are coated with a soluble glass 14 with an elution-slow mold-proof component, and the intermediate layer 12 is coated with the soluble glass 15 with an elution-fast mold- proof component. The elution of the mold-proof component of the lower layer 13 is slow and so, the mold-proof component is not easily dissolved even if the lower layer 13 comes in frequent contact with hot water, and mold-proof effect can be kept for a long time. Besides, the intermediate layer 12 comes in no frequent contact with the hot water, but the elution of the mold-proof component is fast, and so comparatively much mold-proof component is dissolved, and mold is prevented from being generated on the intermediate layer 12, and the mold-proof component is transmitted to the lower layer 13, and the mold is prevented from being generated on the lower layer 13. The upper layer 11 comes not so much contact with the hot water, and the mold-proof effect of the upper layer 11 is sufficient just with dissolved slight mold-proof component, and the dissolved mold-proof component is transmitted to the lower layer 13, and the component is useful for preventing the mold from being generated on the whole bathroom curtain 10.
