    摘要: A lock state occurrence determination apparatus includes a counter, a reset device, a reference time changing device, a lock state determination device, and an invalidation device. The invalidation device performs, in a case where a false determination of occurrence of a lock state of a motor is caused by the lock state determination device due to an operation input to operate a rotation speed of the motor, at least one of a first invalidation operation to invalidate the lock state determination device and a second invalidation operation to invalidate continuation of a counting operation by the counter.

    摘要: A rechargeable power tool includes a direct current motor, a switching circuit, at least one speed setting unit, a duty ratio setting unit, a drive unit, an operation amount detecting unit, an abnormality determining unit, and a determination threshold setting unit. The abnormality determining unit compares an operation amount detected by the operation amount detecting unit and a determination threshold set based on the operation amount to thereby determine whether or not an operation state of the rechargeable power tool is abnormal. The determination threshold setting unit sets the determination threshold in a continuous or stepwise manner in accordance with a rotation speed set by the speed setting unit.

    摘要: Provided are a small-sized, low-cost, and easy-to-use laser optical path length difference detecting device, a laser optical path length difference detecting device, and a coherent optical coupling device. The laser optical path length difference detecting device detects an optical path length difference between propagation paths of a first laser beam (1) and a second laser beam (2), which are mutually coherent when the beams are propagated through two arbitrary optical paths of a plurality of laser beam optical paths. The laser optical path length difference detecting device is provided with an optical path length difference variable means (4) for changing the optical path length difference between the first laser beam (1) and the second laser beam (2), a wavefront inclination generating means (5) for inclining a wavefront of at least one of the first laser beam (1) and the second laser beam (2), and a two-dimensional detector (6) for detecting the interference light intensity distribution of the first laser beam (1) and the second laser beam (2) which have passed through the wavefront inclination generating means.
