Patent number: 10167950Abstract: When engagement of a lockup clutch is initiated, coupling of the lockup clutch is initiated in a state where a working fluid amount is sufficiently ensured by setting a condition that an engine rotation speed is higher than or equal to a limit engine rotation speed. Thus, it is possible to prevent rapid engagement of the lockup clutch. Here, the limit engine rotation speed is appropriately determined on the basis of a line pressure, and it is possible to reduce a delay of coupling of the lockup clutch by ensuring the working fluid amount while preventing rapid engagement of the lockup clutch.Type: GrantFiled: June 17, 2014Date of Patent: January 1, 2019Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Akio Natori, Makoto Sawada, Kiyoshi Watanabe, Takeshi Torii, Toshiaki Hayashi, Masashi Takizawa

Patent number: 6204935Abstract: An image processor reads an original that includes an original image and an attribute instruction image, for designating the contents of the image processing that is performed on the original image. This ensures that image processing is performed in consonance with the contents of the attribute instructions that are indicated by the attribute instruction image. A scanner reads a format original wherein instructions for data attributes, such as a range for a character frame and a character color, are expressed with a bar code. The pattern of the read bar code is analyzed, and the attribute instruction data, such as the range for a character frame and a character color, are temporarily stored in a RAM. An original to be output is read by the scanner and is stored as image data in the RAM. Image processing (color conversion, etc.) that correspond to the attribute instruction data is performed on the image data, and a printer prints image data obtained by performing all of the instructed image processes.Type: GrantFiled: August 23, 1995Date of Patent: March 20, 2001Assignee: Canon Kabushiki KaishaInventors: Tsunenori Soma, Katsumi Masaki, Masayuki Takayama, Hiroshi Netsu, Masashi Takizawa, Makoto Nihei, Koji Kawamura

Patent number: 6061152Abstract: An image processing method and apparatus which makes possible image processing based on attribute specification contents specified by an attribute specification image by reading an original including an original image and the attribute specification image which specifies the contents of processings to be performed on the original image.A scanner reads a format original containing bar codes indicating data attribute specifications such as character limit range, character color, etc. The read bar code patterns are analyzed and the attribute specification data such as character limit range, character color, etc. is stored in RAM once. Then, the original to be output is read and stored in RAM as image data. Processings (such as color conversion, etc.) corresponding to the aforementioned attribute specification data are performed in relation to this image data.Type: GrantFiled: December 15, 1997Date of Patent: May 9, 2000Assignee: Canon Kabushiki KaishaInventors: Makoto Nihei, Katsumi Masaki, Masayuki Takayama, Hiroshi Netsu, Masashi Takizawa, Koji Kawamura

Patent number: 5758043Abstract: An image processing method and apparatus which divides image information into a plurality of predetermined-sized partial images, and sequentially performs designated image processing by partial image, thus enables image processing of the read image data using a small memory capacity. In the apparatus, an image reader reads image information, in accordance with a designated reading size, and stores the read image data, as partial image data, into an image memory. Then, a designated special-effect image processing is performed on the partial image data stored in the image memory. An image output unit sequentially outputs special-effect image processed partial images.Type: GrantFiled: September 5, 1995Date of Patent: May 26, 1998Assignee: Canon Kabushiki KaishaInventors: Masashi Takizawa, Katsumi Masaki, Masayuki Takayama, Hiroshi Netsu, Makoto Nihei, Koji Kawamura
