  • Patent number: 11738980
    Abstract: A capping machine includes a gripper having a pair of gripping arms provided on an outer peripheral portion of a rotating body and configured to grip a cylindrical portion of a vessel, an opening and closing device configured to open and close the gripping arms, and a capping head liftably and rotatably provided on the rotating body. The gripping arms are arranged symmetrically with respect to a radius of the rotating body. The gripper has a protrusion for preventing the vessel from rotating on a vessel gripping surface of the gripping arms. The gripping arms have outer and inner gripping surfaces which are connected in a V shape. The protrusion is formed only on the inner gripping surface of a right gripping arm. A cap held by the capping head is screwed onto the vessel while sticking the protrusion into the cylindrical portion.

  • Patent number: 10128024
    Abstract: An MgB2-based superconducting wire for a liquid hydrogen fluid level sensor which can maintain an unimmersed portion of the MgB2-based superconducting wire for a liquid hydrogen fluid level sensor in a non-superconducting state even without heating the unimmersed portion is provided. A wire for a liquid hydrogen fluid level sensor comprises an MgB2-based superconductor which contains Mg, B, and Al. The critical temperature at which the electrical resistance becomes essentially zero is 20-25 K, and the transition width, which is the difference between the temperature at which the electrical resistance begins to decrease toward zero and the critical temperature, is at most 5 K.

  • Patent number: 8222274
    Abstract: [Problem] To provide a compound which may be used for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS). [Means for Resolution] It was found that a pyrrole derivative characterized by the possession of a guanidinocarbonyl group or amido group as a substituent group at the 3-position, or a pharmaceutically acceptable salt thereof, has a strong antagonism for both of the 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having the antagonistic activity for both of the receptors showed a good pharmacological action in comparison with the case in which an antagonist selective for either one of the receptors was used alone. Based on the above, the compound of the present invention is useful for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).

  • Patent number: 8076348
    Abstract: [Problem] To provide a compound which can be used in the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly in the treatment of irritable bowel syndrome (IBS) and/or prevention of migraine. [Means for Resolution] It was found that an acylguanidine derivative having a tricyclic structure or a pharmaceutically acceptable salt thereof has a strong antagonism to 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having antagonism to both of the receptors showed superior pharmacological action in comparison with the case of the single use of an antagonist selective for either one of the receptors. Based on the above, the compound of the present invention is useful in preventing and/or treating diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly in treating irritable bowel syndrome (IBS) and/or preventing migraine.

  • Patent number: 7985764
    Abstract: It was found that a compound according to the following formula: or a pharmaceutically acceptable salt thereof, has a strong antagonism for both the 5-HT2B and 5-HT7 receptors. In addition, the compound shows good pharmacological action as compared to antagonists selective for only one of these receptors. Based on the above, the compound of the present invention is useful for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
