  • Patent number: 11236862
    Abstract: A lubricant cartridge container includes a cylindrical member, and a moving member moving inside the cylindrical member toward a lubricant inflow portion side as a fluid lubricant flows toward the lubricant inflow portion side when subjected to a suction force from a lubricating pump side. The moving member has a first moving main body portion moving inside the cylindrical member and contacting with a shoulder portion, and a second moving main body portion contacting with the lubricant inflow portion after the first moving main body portion comes in contact with the shoulder portion. The second moving main body portion has a center portion contacting with the lubricant inflow portion, and a step portion connecting the center portion and the first moving main body portion. The center portion has a recess recessed in a polygonal shape formed by connecting a plurality of apexes in a plan view.

  • Patent number: 8331527
    Abstract: An X-ray tube 1 is heated under an X-ray scan condition (tube voltage V, tube current I, exposure time width t) and thus a focal point is shifted. Artifact occurs in a reconstructed image due to the focal point shift. The present invention has an object to enable correction of the focal point shift caused by heating the tube. The applicant and inventor of this application has confirmed that the focal point shift amount of the tube 1 varies in accordance with whether it is in a heating direction or cooling direction when viewed from a past sequence. Therefore, the sequence record and the focal point shift amount based on the heating and cooling directions are stored as data in a storage device 13. A just near past sequence record when viewed from now is stored in a storage unit 16, and the tube temperature is detected by a tube temperature detector 15.

  • Patent number: 5148367
    Abstract: A word processor with a spelling correction function. A spelling error can result from for example, improperly inputted characters or misread characters. When the improperly input or misread characters are not found, for example in a main dictionary or a user's dictionary of the word processor, characters from a probability table are selected to replace the improper characters which have been caused by the spelling errors. The probability tables can be formed by determining from proper inputting into the word processor the highest frequency of appearance order of two characters. In addition, the probability table can be made by determining the frequency of corrections of an improperly inputted character.

  • Patent number: 5096834
    Abstract: A method for the determination of smoke concentration is disclosed which comprises heating a sample smoke containing a SOF (soluble organic fraction) component and a dry soot component to a temperature not lower than the boiling point of the SOF component and not higher than the flash point of the dry soot component during the presence of the action of an oxidation catalyst thereby allowing the dry soot component in the waste smoke to be determined by measurement with a smoke tester in a state not affected by the SOF component.

  • Patent number: 5091878
    Abstract: A word processor may be used in a plurality of languages such as Japanese and English. The word processor has a function of replacing a particular symbol added with an editing symbol with a described character in automatic editing text. The capability of adding of the preferred edit data (edit symbol) to a series of particular symbols is done by arranging newly inputted data in positions of the particular symbols so that the desired edit can be performed. Where a number of newly inputted characters is smaller than that of the particular symbols, they are replaced with space codes or they are deleted. This prevents unnecessary symbols or spaces from remaining in a simplified format.

  • Patent number: 5031711
    Abstract: A conveyance device has a high-temperature pulley and a low-temperature pulley rotatably mounted on a chassis at a prescribed distance from each other and an endless belt constituted of a shape memory alloy is wound around the two pulleys. The high-temperature pulley is maintained at a temperature higher, and the low-temperature pulley at a temperature lower, than the transformation temperature of the shape memory alloy. The pulleys are rotated and the chassis powered to move by the force produced by the shape memory alloy when it restores to its memorized shape.

  • Patent number: 4962465
    Abstract: A character processor for reading a source character from a character generator and outputting it to an output unit after editing. It is provided with a dot pattern correcting function, which includes generating a magnified thick character by magnifying the read souce character pattern. It further includes generating a magnified character contour outline by magnifying the read source character pattern in parallel with the magnified thick character generation, shifting the magnified blanked character in predetermined directions, synthesizing the magnified thick character and the shifted magnified blanked character, removing a domain surrounded by a contour of the magnified blanked character from the magnified thick character, thereby generating a magnified blanked character with a thick contour.
