  • Publication number: 20220302618
    Abstract: It is aimed to shorten a stub length and realize miniaturization. A branch connector (10) includes a pair of terminal fittings (30), a terminal holding member (12) and a shorting member (46). The pair of terminal fittings 30 are fixed to a divided portion (52) at an intermediate position of a conductive path (51A, 51B). The terminal holding member (12) accommodates the pair of terminal fittings (30). The shorting member (46) is disposed along an outer surface of the terminal holding member (12) and connected to the pair of terminal fittings (30). A branch-side terminal (63) is connectable to the terminal fitting (30).

  • Publication number: 20180223326
    Abstract: The present invention relates to a measurement method for complement-dependent bactericidal activity against Streptococcus pneumoniae, and provides a measurement method capable of measuring complement-dependent bactericidal activity against Streptococcus pneumoniae of any capsular serotype. Complement-dependent bactericidal activity against Streptococcus pneumoniae is measured using capsule-deficient Streptococcus pneumoniae, that is, non-encapsulated or substantially non-encapsulated, or transparent Streptococcus pneumoniae. The measurement of the complement-dependent bactericidal activity against Streptococcus pneumoniae of any capsular serotype is enabled.

  • Patent number: 9670219
    Abstract: [Problem] Provided is a compound having a positive allosteric modulating activity (PAM activity) on an ?7 nicotinic acetylcholine receptor (?7 nACh receptor). [Means for Solution] The present inventors have studied on a PAM activity on an ?7 nACh receptor, and they have found that a tetrahydrooxepinopyridine compound has a PAM activity on an ?7 nACh receptor, thereby completing the present invention. The tetrahydrooxepinopyridine compound of the present invention has a PAM activity on an ?7 nACh receptor and can be expected as an agent for preventing or treating dementia, cognitive impairment, schizophrenia, Alzheimer's disease, CIAS, negative symptoms of schizophrenia, inflammatory diseases, or pain.
