Publication number: 20130273407Abstract: A non-aqueous electrochemical cell is disclosed having a heat-resistant coating on at least one of a negative electrode, a positive electrode, and a separator, if provided. The heat-resistant coating may consume heat in the cell to stabilize the cell, act as an electrical insulator to prevent the cell from short circuiting, and increase the mechanical strength and compression resistance of the coated component. In certain embodiments, the heat-resistant coating serves as a solid state electrolyte to produce a solid state electrochemical cell.Type: ApplicationFiled: May 17, 2013Publication date: October 17, 2013Inventors: Kostyantyn KYLYVNYK, Naoki OTA, Hiroyuki YUMOTO

Patent number: 7341802Abstract: A feedthrough is insulated and hermetically sealed by brazing a ceramic disk to a case cover and by brazing the top surface of the ceramic disk to the bottom surface of a feedthrough pinhead. Using this technique instead of forming a compression seal, the surface area for bonding is increased, increasing bond strength. The ceramic disk electrically insulates the feedthrough pin from the cover, and provides a large surface area for mechanically sealing the cell with the braze. Considering the small size of many cells, this increased surface area is important for getting a good seal and increasing bond strength. This design also creates a longer fluid path, providing greater hermeticity. Furthermore, a greater range of component material combinations is available because CTE compatibility limitations of the feedthrough pin, cover, and insulator are minimized. This feedthrough is applicable to broad array of applications and numerous material combinations.Type: GrantFiled: March 25, 2004Date of Patent: March 11, 2008Assignee: Quallion LLCInventors: Naoki Ota, Hiroshi Nakahara, David L.

Patent number: 4998626Abstract: A mail processing machine for sorting mail according to whether the characters of the destination address are printed or handwritten. The mail processing machine reads information of the surface of the mail and distinguishes the area of the destination address from the area of the sender address. The machine has a recognizer to determine printed or handwritten address according to the dispersion (i.e. the statistical variation) of a characteristic of the letters such as the height of letters, the space between letters or lines etc. In this operation, the recognizer calculates the dispersion using the signals corresponding to only the bottom two lines of the address area, which contain important information.Type: GrantFiled: July 8, 1988Date of Patent: March 12, 1991Assignee: Kabushiki Kaisha ToshibaInventor: Naoki Ota

Patent number: 4783825Abstract: A postal material reading apparatus is provided with a mechanism for obtaining an image signal which represents a visual image of the surface of postal material. A detector is provided responsive to that image signal for identifying an area of that image which contains an edge mark that may interfere with orientation analysis of the image. A detector is also provided responsive to the identification of that area for analyzing the image signal for only that portion of the image signal which represents the image outside the area in which the edge mark was detected, to determine the orientation of the postal material. In the preferred embodiment, a histogram is used to identify the area of the image which contains the potentially interfering edge mark.Type: GrantFiled: April 22, 1986Date of Patent: November 8, 1988Assignee: Kabushiki Kaisha ToshibaInventors: Nobuyuki Hirose, Naoki Ota

Patent number: 4481665Abstract: This invention relates to a character segmentation method for use with an optical character reader for sequentially reading postal code, state name and city name postal information, and for generating signals which represent character masks of each character. The system then calculates the gap between each mask and determines if it is greater than an average gap value calculated for all the masks. A determination is also made if a substantially smaller mask (representing a punctuation mark) exists between the two masks. These determinations are used to identify and separate the blocks of information. Once the blocks are identified, the block containing the postal code is classified since it necessarily contains five characters and the two remaining blocks (i.e., state and city) are classified since they, having been scanned in sequence, follow the postal code.Type: GrantFiled: December 16, 1981Date of Patent: November 6, 1984Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventor: Naoki Ota
