Patent number: 11262292Abstract: A fluid delivery method for delivering a liquid sample to a flow cell including a taper section including a first and a second inner walls opposing the first inner wall, which is inclined to the second inner wall so that a distance between the first and the second inner walls at a downstream side of the taper section is shorter than a distance at an upstream side of the taper section, and including measurement flow path provided downstream of the taper section, through which a liquid sample flows together with a sheath fluid. The fluid delivery method includes sample introduction of delivering the liquid sample into the taper section along the second inner wall until the liquid sample reaches the measurement flow path, and sample pressing by delivering the sheath fluid into the taper section along the first inner wall after the liquid sample reaches the measurement flow path.Type: GrantFiled: April 6, 2020Date of Patent: March 1, 2022Assignee: ARKRAY, Inc.Inventors: Shinichi Ota, Shigeki Masuda, Shinya Nakajima

Patent number: 10619759Abstract: A drain plug device is provided with a plug lid, a mounting member inserted in an overflow port, an operation handle provided corresponding to an opening of the mounting member at one end thereof so as to protrude from a surface of a sidewall, a transmission member configured to transmit a driving force generated by a pivoting operation of the operation handle to the plug lid side, and a handle moving mechanism capable of moving the operation handle. The handle moving mechanism is configured to make an amount of protrusion of the operation handle with respect to the surface of the sidewall when the drain port is open smaller than an amount of protrusion of the operation handle with respect to the surface of the sidewall when the drain port is closed. Whereby a good draining efficiency at the overflow port side is secured when draining is performed therethrough.Type: GrantFiled: October 6, 2016Date of Patent: April 14, 2020Assignee: JAPAN ALPHA CO., LTD.Inventors: Shinichi Ota, Kohei Kitagawa
