Patent number: 9745378Abstract: The present inventors obtained, from a phage library of human antibodies, an anti-mouse NR 10 neutralizing antibody-expressing BM095 clone that shows a strong proliferation-suppressing activity in an IL-31-dependent Ba/F3 cell proliferation assay system. When this anti-mouse NR 10 neutralizing antibody was administered to NC/Nga mice, a model of atopic dermatitis which is a mouse model of chronic dermatitis that arises as a result of repeated applications of picryl chloride, a mouse model of rheumatoid arthritis, and a mouse model of osteoarthritis, a significant effect of symptom suppression was observed. This revealed that the anti-NR 10 neutralizing antibody is indeed effective as a therapeutic agent for inflammatory diseases. In addition, the present inventors successfully obtained an anti-human NR 10 neutralizing antibody, providing extremely useful therapeutic agents with practical clinical applications.Type: GrantFiled: April 7, 2015Date of Patent: August 29, 2017Assignee: Chugai Seiyaku Kabushiki KaishaInventors: Masakazu Hasegawa, Hidetomo Kitamura, Hideki Adachi, Keiko Kasutani

Patent number: 8474439Abstract: A fuel vapor processor has a fuel tank, a canister, a recovery pipe, a fuel pump, a negative pressure generator, a pressure regulator, a fuel intake pipe and a fuel intake regulator. The vapor pipe leads the fuel vapor generated in the fuel tank into the canister for trapping the fuel vapor. The recovery pipe connects the fuel tank and the canister for recovering the fuel vapor trapped in the canister into the fuel tank. The fuel intake pipe directly connects the fuel pump provided in the fuel tank with the negative pressure generator for leading fuel to the negative pressure generator. The negative pressure generator generates negative pressure depending on an amount of fuel supplied to the negative pressure generator from the fuel pump. The fuel vapor trapped in the canister is recovered to the fuel tank through the recovery pipe due to the negative pressure. The pressure regulator is connected with the fuel pump for returning excess fuel discharged from the fuel pump into the fuel tank.Type: GrantFiled: May 3, 2010Date of Patent: July 2, 2013Assignee: Aisan Kogyo Kabushiki KaishaInventors: Katsuhiko Makino, Junya Kimoto, Masanobu Shinagawa, Takashi Mani, Masakazu Hasegawa

Publication number: 20120186563Abstract: A canister has a canister case, an adsorbent chamber defined in the canister case, and an adsorbent disposed in the adsorbent chamber. The adsorbent can adsorb fuel vapor as the fuel vapor flows through the adsorbent chamber in a first direction. On the other hand, the adsorbent allows desorption of fuel vapor as air flows through the adsorbent in a second direction opposite to the first direction. The adsorbent chamber includes a first adsorbent chamber and a second absorbent chamber communicating with each other. The first adsorbent chamber is disposed on an upstream side of the second adsorbent chamber with respect to the first direction. The adsorbent includes a first adsorbent disposed in the first adsorbent chamber and a second adsorbent disposed in the second adsorbent chamber. A desorption promoting device is disposed in the second adsorbent chamber and can promote desorption of fuel vapor from the second adsorbent.Type: ApplicationFiled: January 23, 2012Publication date: July 26, 2012Applicant: AISAN KOGYO KABUSHIKI KAISHAInventors: Masakazu HASEGAWA, Hiroshi SUGIURA, Hiroshi TAKAMATSU, Masahiro SUGIURA
