Patent number: 11236862Abstract: 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.Type: GrantFiled: October 30, 2017Date of Patent: February 1, 2022Assignee: LUBE CO., LTD.Inventor: Keizo Saito

Patent number: 8331527Abstract: 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.Type: GrantFiled: March 2, 2009Date of Patent: December 11, 2012Assignee: Hitachi Medical CorporationInventors: Takashi Ishikawa, Keizo Saito

Patent number: 5200892Abstract: An electronic word processor comprises a memory storing print data, a print wheel, and a check circuit for checking whether the type of the print wheel is suitable for printing out the print data. In the second form, the processor may store word data accompanied with hyphenate data in a selected group of words. In the third form, the processor may comprise a message memory for storing message sentences, and a modification circuit for modifying the message data. In the fourth form, the processor may comprise a control circuit featured in that one or more specific letters can be retrieved and replaced by one or more new letters in the unit of chapter.Type: GrantFiled: April 22, 1991Date of Patent: April 6, 1993Assignee: Sharp Kabushiki KaishaInventor: Keizo Saito

Patent number: 5148367Abstract: 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.Type: GrantFiled: December 17, 1990Date of Patent: September 15, 1992Assignee: Sharp Kabushiki KaishaInventors: Keizo Saito, Kazuhiko Matsuo, Hiroko Murai

Patent number: 5091878Abstract: 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.Type: GrantFiled: November 8, 1988Date of Patent: February 25, 1992Assignee: Sharp Kabushiki KaishaInventors: Hiroyuki Nagasawa, Jun Inoue, Katsunori Takeda, Keizo Saito, Hiroko Murai

Patent number: 4962465Abstract: 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.Type: GrantFiled: December 28, 1988Date of Patent: October 9, 1990Assignee: Sharp Kabushiki KaishaInventors: Keizo Saito, Masanobu Watanabe
