Abstract: An X-ray imaging apparatus is provided with a front side operation unit provided on a front side of a ceiling-suspended support unit to operate a movement of the ceiling-suspended support unit by a drive unit from a front side of the ceiling-suspended support and a rear side operation unit provided on a rear side of the ceiling-suspended support unit with respect to the front side operation unit and configured to operate the movement of the ceiling-suspended support unit by the drive unit from a rear side of the ceiling-suspended support.

Abstract: A thermal convection generating chip (1) includes a rotatory body (2), a thermal convection pathway (11) provided in the rotatory body (2), and a supply path (12A to 12C) that supplies a liquid to the thermal convection pathway (11). The supply path (12A to 12C) includes a liquid receiving section (121) that receives the liquid and a suction passage (122) that provides communication between the liquid receiving section (121) and the thermal convection pathway (11). The suction passage (122) has a first region (122a) extending between a midsection of the suction passage (122) and the thermal convection pathway (11), and a second region (122b) extending between the midsection and the liquid receiving section (121). The liquid in the first region (122a) is separated from the liquid in the second region (122b) through rotation of the rotatory body (2) to be supplied to the thermal convection pathway (11).
