Publication number: 20200056029Abstract: [Object] To provide a technology for imparting favorable slidability to fluorine rubber. [Solving Means] A composition for a sealing member includes: 100 parts by weight of an uncrosslinked fluorine rubber component; and 0.5 to 50 (inclusive) parts by weight of a particulate resin. The particulate resin includes a compatible portion and a lubrication portion, the compatible portion having compatibility with the fluorine rubber component, the lubrication portion having lubricity with respect to the fluorine rubber component. During molding of the composition for a sealing member, crosslinking of the fluorine rubber component progresses and at least a part of the particulate resin moves to a surface due to an action of the lubrication portion. As a result, a surface layer portion including a compatible portion and a lubrication portion is formed on a surface of a molded sealing member.Type: ApplicationFiled: March 27, 2018Publication date: February 20, 2020Inventors: Shiori IRIE, Yasuhiro GUNJI, Noriaki YAMAMOTO, Hajime YANAGAWA

Publication number: 20200040175Abstract: [Object] To provide a ring-shaped sealing member having both the sealing property and slidability. [Solving Means] A sealing member is formed in a ring shape and has a sliding surface. The sealing member includes: 100 parts by weight of fluorine rubber; and 0.5 to 50 (inclusive) parts by weight of a particulate resin. The particulate resin includes a compatible portion and a lubrication portion, the compatible portion having compatibility with the fluorine rubber, the lubrication portion having lubricity with respect to the fluorine rubber. A Shore A hardness measured using the sliding surface as a pressing surface is not less than 80. In this sealing member, since rubber elasticity is achieved by the fluorine rubber, a favorable sealing property can be realized. Further, it is possible to impart high slidability to the sealing member by the action of the lubrication portion of the particulate resin. Therefore, this sealing member has both the sealing property and slidability.Type: ApplicationFiled: March 27, 2018Publication date: February 6, 2020Inventors: Akihiro OWADA, Takashi SHINADA, Takuya OKAMOTO, Shiori IRIE, Yasuhiro GUNJI, Noriaki YAMAMOTO, Hajime YANAGAWA

Patent number: 10408827Abstract: A combination of surface plasmon field enhanced fluorescence spectroscopy (SPFS) and isotachophoresis (ITP) technologies for detecting biomolecules is disclosed. It uses ITP to preconcentrate the reactants and accelerate the reaction, and then delivers the reacted sample to an SPFS sensor for detection. A microfluidic device with a T-junction is provided, which has two reservoirs respectively containing a low-mobility trailing electrolyte buffer and a high-mobility leading electrolyte buffer, and a main fluid channel between the two reservoirs, where the SPFS sensor is located on a side channel joined to the main channel.

Patent number: 10401354Abstract: A biosensor using a decoupled microfluidic device, which has a capture chamber and a detection chamber separate from and in fluid communication with each other. The sensing method is based on particle aggregation via homogeneous reactions, by employing microparticles having antibodies on their surfaces which can form aggregates through antigen mediation. Either size-separation or magnetic based separation is used to separate aggregates from single microparticles; the aggregates are later dissociated and the resulting single microparticles are counted to measure the amount of the antigen. Another biosensor uses a decoupled microfluidic device with a capture chamber and a detection chamber, and a 3-D structure in the capture camber to increase immobilized antibody concentration. Immunoreaction efficiency is improved by increasing the number of antibody per reaction volume in the capture chamber.Type: GrantFiled: October 27, 2017Date of Patent: September 3, 2019Assignee: KONICA MINOLTA LABORATORY U.S.A., INC.Inventor: Noriaki Yamamoto

Patent number: 10180425Abstract: A DNA ligand capable of structural changes upon binding to a target is used as a molecular switch with a SPFS (surface plasmon field-enhanced fluorescence spectroscopy) biosensor to realize one-step SPFS biosensing with rapid turnaround time. The SPFS biosensor has a thin metal film on a prism; when a light of a certain wavelength irradiates on the prism at a certain angle, a strong electrical field is generated at the surface of the metal film. The DNA is immobilized on the metal film surface with its free terminal modified with a fluorescent marker. Without the target, the DNA is folded and the fluorescent marker is located in the region of metal quenching near the metal surface. Upon binding to the target, the DNA is extended and the fluorescent marker is located in the region of enhanced electric field near the metal surface and emits a strong fluorescent signal.Type: GrantFiled: September 1, 2015Date of Patent: January 15, 2019Assignee: KONICA MINOLTA LABORATORY U.S.A., INC.Inventor: Noriaki Yamamoto
