  • Publication number: 20250100405
    Abstract: A vehicle charging device includes a connector engaged with an inlet, a support member, a coupling mechanism that couples the connector with the support member, an arm that raises and lowers the support member by rotating, and a control unit. The control unit sets a rotational position of the support member to be a predetermined rotational position when causing a distal end of the connector to be opposed to an opening part of the inlet, and the predetermined rotational position is a rotational position where the distal end of the connector first abuts on the inlet when raising the support member, and an inclination angle of the connector coincides with an inclination angle of the inlet when the support member is raised to a target position.

  • Patent number: 12257557
    Abstract: The present invention addresses the problem of providing a bonded body which has a high airtightness and exhibits excellent durability under high-temperature and high-pressure conditions. This problem is solved by a bonded body in which a complex of a zeolite and an inorganic porous support, and a dense member are bonded together by an inorganic glass or an inorganic adhesive. The inorganic glass or the inorganic adhesive has a thermal expansion coefficient of 30×10?7/K to 90×10?7/K, and the inorganic glass has a softening point of 550° C. or lower. The present invention also addresses the problem of providing a method of efficiently producing an alcohol by installing a separation membrane in an alcohol synthesis reactor based on a bonding method that gives good sealing performance and durability under high-temperature and high-pressure conditions and in the presence of methanol vapor.
