Abstract: Provided is an electrode treat rent method comprising a peeling step that involves grind ng, with a grinding means, an electrode in which an electrode mixture is held on a collector, and peeling the electrode mixture from the collector, the electrode treatment method Characterized in that the grinding means has a first member (3) that has a grinding surface and a second member (4) that has a grinding surface, and the first member (3) and the second member (4) are disposed so that the grinding surfaces of the first member (3) and the second member (4) face each other and a space for grinding the electrode is formed between the members, and at least one among the first member (3) and the second member (4) is a grinder that rotates around the direction in which the grinding surfaces face each other and which serves as the rotational axial direction.

Abstract: According to one embodiment, a disk device includes a housing, magnetic disks in the housing, and a printed circuit board attached to an outer surface of a bottom wall of the housing. The housing includes a base including a bottom wall and a side wall, and at least two base-side positioning portions provided on the bottom wall in a region overlapping the side wall. The printed circuit board includes at least two board-side positioning portions each engaged with the base-side positioning portion. One of the base-side positioning portion and the board-side positioning portion includes a pin extending substantially perpendicular to the bottom wall, and another includes a hole into which the pin is fitted.

Abstract: An automatic laser beam machining apparatus with a sensor that detects whether a user slots a fare (e.g. coins) for starting laser beam machining of an article. The apparatus includes a video camera that can take an image (such as the face of a user) and reproduce it by laser machining upon an article. The article is removed from a stack of the articles and automatically properly positioned for laser machining with safety and ease. A mark is provided on the article for detecting the machining condition (e.g. the material or a shape of the article) by using a sensor.

Abstract: An improved coin stacking apparatus is shown which builds the stack by placing each successive coin at the bottom of the stack made of the preceding coins. This makes the device more compact in the vertical direction. The coins are stacked by a movable wheel or belt which has a coin engagement device that engages the leading edge of the coin. The wheel or belt further includes a coin displacement device which vertically displaces the stack to allow the succeeding coins to slide beneath the stack.

Abstract: Each unit number of coins to be stacked and wrapped are centrifugally aligned on a rimmed turntable and fed in a row along a horizontal coin guideway to a stacking position, where the successive coins are stacked by a toothed stacking wheel capable of placing each new coin under the preceding one. Thus the coins are stacked on, rather than under, the plane of the coin guideway with a view to the reduction of the vertical dimension of the machine to a minimum. Disposed around the stack of coins thus formed are a set of parallel wrapping rolls at least one of which is displaceable for rotatably engaging the coin stack between itself and the other wrapping rolls. With the forced rotation of the wrapping rolls together with the coin stack, a piece of wrapper strip is wound around the latter, and the side edges of the wrapper strip are folded against the opposite ends of the stack. The wrapped stack of coins is ejected downwardly.
