Abstract: An amount of heat generated in a substrate is suppressed when discharging a battery. When a first switch is in a conductive state, power of a first battery is consumed by a first resistance element provided in a first wiring and a second resistance element provided in a substrate.

Abstract: A reference core position calculation device 100 that calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unit 101 and a calculation unit 112. The measurement unit 101 measures a dimension of each portion of the elevator shaft. The calculation unit 112 calculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit 101. When the reference core position is a first reference core position, the calculation unit 112 determines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.

Abstract: The present invention provides an intra-hoistway measurement system automatically measuring dimensions within an elevator hoistway prior to elevator installation to reduce labor of workers. An intra-hoistway measurement system according to the present invention includes: a reference laser device that is mounted to a structure on a ceiling or in an upper portion of the hoistway for an elevator and emits a laser beam toward a lowermost part; a mobile measuring device that has a plane measuring device to measure horizontal dimensions within the hoistway; and a moving device that is mounted to the structure on the ceiling or in the upper portion of the hoistway and moves the mobile measuring device up and down. The mobile measuring device has a reference laser detection device that detects the laser beam emitted from the reference laser device, and an attitude detection device that detects its own attitude.

Abstract: A work machine unit includes: a support member assembled to an end effector connection part of an operating machine; a work machine part assembled to one end of the support member; and a linear guide disposed at another end of the support member across its connection to the end effector connection part from the support member, arranged in parallel to an axial direction of the work machine part, and configured to abut against a work object or its peripheral structural object. Further, the linear guide is passed through a through-hole formed in the support member, and the support member is configured to move in the axial direction of the work machine part as guided by the linear guide.

Abstract: In a heat exchanger, when louvers are viewed from an airflow direction, a louver tip end width becomes shorter with increase of a louver height. A fin width of the fin is 14 mm or shorter. Airflow-end louver lengths of an upstream-end first louver, a downstream-end first louver, an upstream-end second louver, and a downstream-end second louver are “?×LP” or longer, where LP is a louver pitch.
