  • Patent number: 10173298
    Abstract: A stop lever is provided for a power tool having a gear case and a guard member. The reversible stop lever is coupled to the gear case via a fastener. The stop lever includes a first arm and a second arm, and the fastener is removable to position the stop lever such that the first arm or the second arm of the stop lever engages the guard collar. The first arm includes a first surface and a second surface that are angled such that the guard collar can be rotated in a one direction without actuation of the second arm, but not in the opposite direction. The second arm of the stop lever includes surfaces that are angled to prevent rotation of the guard collar in either direction unless the second arm is actuated about the fastener.

  • Patent number: 10138548
    Abstract: Eddy current formable in a polishing target is detected as an impedance by an eddy current sensor. A resistance component and a reactance component of the impedance are associated with respective axes of a coordinate system having orthogonal axes, respectively. An angle calculator calculates the tangent of an intersection angle between a first straight line connecting a first point corresponding to an impedance for a zero film thickness, and a second point corresponding to an impedance for a non-zero film thickness, and a diameter of a circle passing through the first point. A film thickness calculator determines the film thickness from the tangent.
