Publication number: 20060244795Abstract: An ink tank detachably mounted on a printer includes a non-volatile memory and a LED for executing a process in response to a condition of the tank such as ink residual quantity by transmitting information stored in the memory to a printer, and informing the condition of the ink by use of the LED. Further, the content stored in the memory is prevented from being destroyed, and the LED can perform light emission until immediately before detachment and thus contribute to improvement in workability of a user. A volatile memory element is provided in addition to the non-volatile memory. When a user can detach the tank, condition information on the ink tank retained by the non-volatile memory is transferred to the volatile memory in advance. When it is possible to detach the tank, control for turning the LED on and off is achieved by accessing only to the volatile memory.Type: ApplicationFiled: December 19, 2005Publication date: November 2, 2006Applicant: CANON KABUSHIKI KAISHAInventors: Kimiyuki Hayasaki, Kenjiro Watanabe, Nobuyuki Hatasa, Tatsuhiko Yamazaki

Publication number: 20060238558Abstract: Disclosed is a printing head having connection terminals for performing an electrical connection of signals including drive signals of print elements by contacting connection terminals in an apparatus side when the head is mounted onto an ink jet printing apparatus. It is made to guarantee connections of all terminals by detecting contacts of a part of terminals. Among the terminals in the head, terminals whose distances from the connection terminals in the printing apparatus become maximum when a deviation occurred in the mounting, are used as terminals for contact detection. For example, from among the connection terminals arranged in a planar area, which is rectangular-shaped, terminals positioned in corners are used as the terminals for the contact detection. When the contacts of these terminals are detected, the connections of all the terminals inside the area can be guaranteed.Type: ApplicationFiled: April 17, 2006Publication date: October 26, 2006Applicant: CANON KABUSHIKI KAISHAInventors: Nobuyuki Hatasa, Kenjiro Watanabe, Kimiyuki Hayasaki, Keiichiro Tsukuda, Takuya Hatsui

Publication number: 20060125889Abstract: A package is formed including an ink tank in a bag. A cap is attached to an ink supply port of the ink tank. In the cap including an adsorption material made of zeolite, the adsorption material is arranged in a position in the cap where the adsorption material does not interfere with the ink tank when the cap is attached to the ink tank. By this arrangement, it is possible to adsorb ammonia gas issuing from the ink tank and hold down the amount of ammonia gas that reacts with electrodes of the substrate on the ink tank. Zeolite adsorbs and releases ammonia gas and does not adsorb ammonia gas limitlessly; therefore, it is possible to prevent notable changes in the composition of components of the ink stored.Type: ApplicationFiled: December 6, 2005Publication date: June 15, 2006Applicant: Canon Kabushiki KaishaInventors: Takatoshi Kitagawa, Kenjiro Watanabe, Nobuyuki Hatasa

Patent number: 6934240Abstract: An optical element is provided in which in a lens surface substantially perpendicular to the optical axis of the lens, there is embedded a conductive member whose diameter or width is smaller than the diameter of an optical spot incident upon the lens surface. The optical element is used in an optical head which reads a signal by illuminating an optical recording medium with a reading light. The basic principle of this optical head is such that a subtle phase change of the light is detected which is caused by the electromagnetic interaction between the conductive member embedded in the optical element and a conductive material on the surface of the optical recording medium. For example, the interference between return light beams from the optical recording medium is used to read a signal.Type: GrantFiled: April 13, 2001Date of Patent: August 23, 2005Assignee: Sony CorporationInventors: Kenjiro Watanabe, Hitoshi Tamada
