Patent number: 9952606Abstract: In an embodiment, control is performed to operate a three-way valve in accordance with a reaching ratio of pH adjustment. When process of certain steps is performed, bubbles of ammonia generated in a nebulizer can be extruded by air so as to be injected from an injection port together with aqua ammonia remaining in the nebulizer. Therefore, the pH adjustment can be performed while a large amount of bubbles of ammonia are prevented from being generated in the nebulizer.Type: GrantFiled: July 15, 2014Date of Patent: April 24, 2018Assignees: SYSTEM INSTRUMENTS CO., LTD., NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGYInventors: Toshiharu Kuroda, Michio Horiuchi, Yanbei Zhu, Koichi Chiba

Patent number: 9520278Abstract: An object is to mix multiple liquids sufficiently and then nebulize the mixed liquids while maintaining the nebulizing efficiency. A nebulizer includes a first inner tube disposed inside an outer tube and having therein a first sample passage through which a first liquid sample flows, a second inner tube disposed inside the outer tube in parallel with the first inner tube and having therein a second sample passage through which a second liquid sample flows, a membranous member disposed with a gap between the membranous member and sample outlets formed at respective ends of the inner tubes. The gap forms mixing space in which a gas passing through a gas passage converts the first and second liquid samples flowing out of the sample outlets into droplets and mixes the droplets and the membranous member has multiple holes through which the mixed liquid samples pass along with the gas.Type: GrantFiled: January 15, 2015Date of Patent: December 13, 2016Assignees: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY, S.T.

Patent number: 7016535Abstract: Collation can be carried out at a high speed without reducing the accuracy thereof, whereby processing of identifying documents is accurately performed at a high speed. To this end, characteristic data of a predetermined pattern is registered in advance. Characteristic data in a first area greater than an area of the predetermined pattern registered in advance in an image to be identified is compared and collated with characteristic data of the predetermined pattern. A second area smaller than the first area is cut out from the first area based on the result of comparison, so that characteristic data of an image in the second area is compared and collated with the characteristic data of the predetermined pattern, thus making it possible to identify the predetermined pattern contained in the image based on the result of comparison.Type: GrantFiled: November 16, 2001Date of Patent: March 21, 2006Assignee: Fujitsu LimitedInventors: Toshiyuki Waida, Shinichi Eguchi, Kouichi Kanamoto, Maki Yabuki, Koichi Chiba, Katsutoshi Kobara, Osamu Sato, Kazunori Yamamoto, Yutaka Katsumata

Publication number: 20040125490Abstract: An agravity sensor is a mechanical switch which is opened in an agravity state. A CPU determines based on the output from this agravity sensor if the self apparatus is falling. If it is determined that the self apparatus is falling, the CPU instructs an IDE interface controller to transmit an unload command for retracting a magnetic head to an HDD. At this time, the CPU uses, as the unload command, a reset signal independent from general commands such as a read signal, write signal, and the like, which are processed by the HDD in the order they are accepted.Type: ApplicationFiled: September 30, 2003Publication date: July 1, 2004Inventors: Masao Fujiki, Hiroshi Sawabe, Koichi Chiba, Koichi Kobayashi

Patent number: 6694065Abstract: An image collating apparatus and an image collating method, in which a document larger than an image reader can be collated using a preregistered image even in the case where the document is read by the image reader, are disclosed. The image of the document read by the image reader is collated sequentially with the document images of different sizes preregistered in a data base. The document size is determined from the document image input from the image reader. In the case where the document size is smaller than the preregistered image size, the preregistered image is retrieved in accordance with the document size, so that the document features are extracted and matched between the read document image and the registered image set in size to each other, thereby collating the read image with the preregistered image.Type: GrantFiled: December 11, 2000Date of Patent: February 17, 2004Assignee: Fujitsu LimitedInventors: Katsutoshi Kobara, Shinichi Eguchi, Kouichi Kamamoto, Maki Yabuki, Koichi Chiba, Toshiyuki Waida, Kazunori Yamamoto, Yutaka Katsumata

Patent number: 6549662Abstract: Characters of data on a document are recognized by automatically determining the definitions of characters of the data from the arrangement of character strings of the data. Character strings on the document are extracted by reading the document, and headers and data on the document are distinguished from each other by determining the positional relationship between the character strings. Character attributes of the data are determined by recognizing characters of the character strings of the headers using a header recognition dictionary. Characters of the character strings of the data are recognized according to the determined character attributes of the data. Since character attributes of the data are determined from recognized characters of the headers after the headers and the data are distinguished from each other from the layout on the document, it is possible to enter automatically the character attributes of the data.Type: GrantFiled: May 27, 1998Date of Patent: April 15, 2003Assignee: Fujitsu LimitedInventors: Katsutoshi Kobara, Shinichi Eguchi, Yoshihiro Nagano, Hideki Matsuno, Koichi Chiba, Yutaka Katsumata
