Abstract: A drive device for an in-core neutron instrumentation system includes a safety circuit between a power supply and a drive motor. The safety circuit is provided inside the cover member, and switches between a conductive state in which power can be supplied to the drive motor and a cut-off state in which power cannot be supplied thereto depending on a mounted state of the cover member. The safety circuit is controlled to be in the conductive state in response to a state in which the cover member is mounted on the base member, and is controlled to be in the cut-off state in response to a state in which the cover member is not mounted on the base member.

Abstract: In a transmission remote control assembly of a tilt-cab type vehicle a first link mechanism connected to a change lever, a second link mechanism connected to a transmission lever or levers and at least one connecting means comprising a pair of connecting members respectively connected to the first and second mechanisms are so arranged that when a cab body is in a horizontal stationary state, the pair of connecting members are in connecting engagement whereby the change and transmission levers may co-operate whereas when the cab body undergoes inclining movement, the pair of connecting members are disengaged so as to disconnect the first and second link mechanisms.
