Patent number: 11959892Abstract: A liquid chromatograph is presented which enables automatic resolution of a liquid sending failure when the liquid sending failure caused by a liquid sending pump occurs, and execution of a new analysis with good reproducibility after the liquid sending failure is resolved. The liquid sending failure can be automatically resolved by a purging operation. A sample remaining in the analysis flow path is washed away by a non-injection analysis after the liquid sending failure is resolved, and a new analysis can be executed with good reproducibility.Type: GrantFiled: March 6, 2019Date of Patent: April 16, 2024Assignee: SHIMADZU CORPORATIONInventors: Hiroshi Ohashi, Takayuki Kihara, Hiroshi Miura

Patent number: 7676029Abstract: To provide a technology indicating guidance for a usage method of information equipment and for solving an abnormality of the information equipment to not only users having knowledge about terminology of the information equipment but also users having none of the knowledge about the terminology of the information equipment. A guidance apparatus receives identifying information of information equipment from a device, reads an image from a database containing images about the information equipment with respect to the received identifying information, creates guidance information containing the read image, transmits the created guidance information to the device, receives information determined by a manipulation about the guidance information on the device, and controls so as to read the image used next for the guidance information from the received information.Type: GrantFiled: March 27, 2006Date of Patent: March 9, 2010Assignee: Fujitsu LimitedInventors: Takayuki Ohashi, Ryu Shibata, Kazunari Kawai, Shoichiro Nakae, Masafumi Katsumata

Patent number: 6288583Abstract: For frequency change, the VCO is controlled through a sub-charge pump circuit to make a determination as to whether or not a difference of dividing data between before and after the change is within a predetermined range. When it is determined that the difference is outside the predetermined range, the loop filer is forcibly charged in a charge time which is determined proportional to the difference in the dividing data, to thereby control an oscillation frequency of the VOC. A large VOC oscillation frequency change can be swiftly realized. Also, while the frequency change circuit is controlling the oscillation frequency, a time constant of the loop filter in the PLL circuit is preferably set at a small value, so that frequency change by the frequency change circuit can be swiftly achieved.Type: GrantFiled: November 22, 1999Date of Patent: September 11, 2001Assignee: Sanyo Electric Co., Ltd.Inventors: Toshiyuki Ozawa, Kazuhiro Kimura, Hiroyoshi Kaneyama, Takayuki Ohashi, Akira Yamazaki

Patent number: 5369064Abstract: This invention relates to a shaped fibrous material for use in the manufacture of fiber-reinforced metals comprising a uniform mixture of ceramic fibers and aluminum borate whiskers. The invention also relates to a method for producing the shaped fibrous material comprising the steps of dispersing ceramic fibers and aluminum borate whiskers in a suitable solvent containing a binder to form a slurry, transferring the slurry into a suction molding, aspirating and dehydrating the slurry to form a shaped dehydrated fibrous material, and drying and firing the shaped dehydrated fibrous material to obtain the shaped fibrous material. The shaped fibrous material can be cast efficiently into a fiber-reinforced metal with a high yield. The thus produced fiber-reinforced metal has a high wear resistance combined with a very mild nature of attacking the mating member.Type: GrantFiled: May 27, 1992Date of Patent: November 29, 1994Assignees: Nichias Corporation, Nissan Motor Co., Ltd.Inventors: Takayuki Ohashi, Kenichi Shibata, Junichi Ogawa, Mitsushi Wadasako
