Patent number: 8328316Abstract: This invention is directed to provide an inkjet printhead, printing apparatus, and printing method capable of correcting a shift of the printing position caused by variations of the discharge characteristic between nozzles. To accomplish this, the inkjet printhead includes memories which hold block numbers used to time-divisionally drive nozzles. The block numbers are written in consideration of the discharge characteristics of the printhead during the manufacturing process of the printhead. When the inkjet printhead is mounted in the printing apparatus, the printing apparatus reads out block numbers corresponding to respective nozzles from the memories. Based on the numbers, the printing apparatus changes block selection signals for the respective nozzles, and transfers the changed block selection signals to the inkjet printhead to drive it.Type: GrantFiled: October 19, 2010Date of Patent: December 11, 2012Assignee: Canon Kabushiki KaishaInventor: Souhei Tanaka

Patent number: 7500739Abstract: Replacement of a recording head on a recording apparatus is detected on the basis of a serial number allocated to each recording head. The recording head also carries head characteristic information such as color information, shading information and so forth. When the recording head is replaced with a new one, the head characteristic information of the newly mounted recording head is automatically stored, so that head driving conditions are automatically determined to optimize the recording conditions without requiring any manual adjustment. Recovery operation is automatically executed when replacement of the recording head is detected, so that required recording conditions are recovered without manual instructions.Type: GrantFiled: November 1, 2004Date of Patent: March 10, 2009Assignee: Canon Kabushiki KaishaInventors: Yasuhiro Numata, Kazuyoshi Takahashi, Yoshiaki Takayanagi, Souhei Tanaka, Hiroshi Tajika, Noribumi Koitabashi, Hitoshi Sugimoto, Miyuki Fujita

Publication number: 20070055422Abstract: A vehicular data recording device enabling a driver to get to know more about his driving technique to improve it. Not only images from a monitoring camera when a shock is detected are simply recorded in a memory card, but also images from the monitoring camera when no shock is detected are always updated and recorded in an HDD successively. Accordingly, images from the monitoring camera in various situations not leading to an accident can be surely supplied to a driver. This prompts the driver to reflect the driving thereof based on the images from the monitoring camera in the various situations. This can allow the driver to figure out the driving skill thereof, and improve the driving skill.Type: ApplicationFiled: September 5, 2006Publication date: March 8, 2007Applicant: HONDA ACCESS CORP.Inventors: Hiroyasu Anzai, Souhei Tanaka
