  • Patent number: 9952606
    Abstract: 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.

  • Patent number: 9520278
    Abstract: 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.

  • Patent number: 9384956
    Abstract: A nebulizer characterized in being provided with: an inner tube, which is disposed coaxially with an outer tube in which a nebulizing outlet is formed and which, together with the outer tube, forms a gas channel therebetween; a sample channel, which is formed inside the inner tube and through which a liquid sample to be nebulized flows; and a reticular membrane disposed with a gap from the sample outlet that is formed at one end of the inner tube and in which multiple holes, through which liquid sample drops flowing out from the sample outlet pass along with a gas, are formed. Using the nebulizer, the particle size of the nebulized liquid droplets can be made uniformly fine over a broad range of sample liquid flow volumes while retention of sample liquid in the nebulizer is reduced.

  • Patent number: 7016535
    Abstract: 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.

  • Publication number: 20040125490
    Abstract: 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.

  • Patent number: 6694065
    Abstract: 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.

  • Publication number: 20030123176
    Abstract: There is disclosed a disk drive which uses a specific command (extended command) such as an AV command other than a usual read/write command. The preset disk drive processes a command issued from a host system as a usual read/write command, when the command is a specific command registered beforehand. Moreover, the present disk drive stops read/write access when the command is other than the usual read/write command and is an unregistered specific command.

  • Patent number: 6556701
    Abstract: Disclosed are a method of and an apparatus for extracting a dotted line from an binary image of a document, and a storage medium thereof. The isolated points are extracted from the binary image. The isolated points configuring a candidate of the dotted line are extracted based on a positional relationship between the extracted isolated points. A validity of the isolated points configuring the candidate of the dotted line is checked. The dotted line from a positional relationship between groups of the extracted isolated points of the candidate of the dotted line. The dotted line can be thereby precisely extracted even if some isolated points are lost due to an. under-density of the image etc.

  • Patent number: 6555063
    Abstract: In order to quickly and economically evaluate cleanliness of a metal with high representativity when quantities, compositions, etc., of non-metallic inclusion particles existing in a metal and resulting in product defects are evaluated by a sample collected during the production process of the metal, the present invention provides an evaluation method involving the steps of levitation-melting a metal piece for a predetermined time by cold crucible levitation-melting means, discharging non-metallic inclusion particles contained in the metal piece to the surface of a molten metal, and directly analyzing a curved and non-smooth sample surface after solidification by a fluorescent X-ray analysis method using an energy dispersion type spectroscope, or by other chemical or physical measurements, to measure or analyze the quantities of elements constituting the non-metallic inclusion particles and to determine quantity of the non-metallic inclusions.

  • Patent number: 6549662
    Abstract: 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.
