摘要： Provided is a seal member or a ball joint capable of satisfactorily maintaining sealing performance between a ball portion of a ball shank and a ball receiving portion of a holder for a long time even when the ball shank is used under a condition that the ball shank is pivoted repeatedly with respect to the holder at a large pivot angle and at high speed. The seal member includes: a base portion having an annular ring shape and is to be fixed to the holder; a retaining portion formed on an inner peripheral side of the base portion integrally with the base portion and is recessed into a conical shape toward the holder; and a lip portion formed along an inner peripheral edge of the retaining portion so as to be held in sliding contact with a spherical surface of the ball portion of the ball shank.

摘要： A new position control apparatus is provided which can reduce deviation caused by a non-linear spring characteristic of a rolling apparatus. In a position control apparatus (5) that controls the position of a movable body (1), in a positioning apparatus (9) including a rolling apparatus (2), a deviation e(t) or d of the movable body 1 caused by the non-linear spring characteristic of the rolling apparatus (2) is subtracted from or added to a position command Xref or r of the movable body (1). The deviation d is calculated by carrying out equivalent exchange on a control circuit for a friction force of the rolling apparatus (2), which is set as a quantity of the dimension of displacement.

摘要： A guide apparatus is provided which can increase a holding force that holds a table, a drawer, a cabinet, a device, or the like at a predetermined position. An engagement body (43) is placed on a second member (42b). A pair of plate spring portions (44a and 44b) is placed on a first member (41) in such a manner as to sandwich the engagement body (43). The pair of plate spring portions (44a and 44b) bend in such a manner that a minimum dimension between the pair of plate spring portions (44a and 44b) is smaller than a dimension (length) of the engagement body (43). In a state where the engagement body (43) has gone beyond a minimum dimension position (53) between the pair of plate spring portions (44a and 44b) and the second member (42b) is being held at a predetermined position on the first member (41), the minimum dimension between the pair of plate spring portions (44a and 44b) is smaller than the dimension (length) of the engagement body (43), and both end portions (44a1, 44a3, 44b1, and 44b3), in a length direction, of the plate spring portions (44a and 44b) are supported by the first member (41).

摘要： This pressing device includes an actuator, a pressing unit provided on a movable element of the actuator, a movement quantity detector for detecting a movement quantity of the movable element and outputting movement quantity information indicating the movement quantity, and a drive device that moves the pressing unit to press a pressed object by supplying a drive current to the actuator based on the movement quantity information. The drive device controls an operation of the pressing unit using position control processing based on current information indicating the drive current and the movement quantity information. When the speed of the pressing unit is decelerated down to a predetermined lower limit speed, the drive device controls the speed of the pressing unit to be constant based on the current information, and when the current reaches a predetermined current value, determines that the pressing operation is performed.

摘要： A mechanical hand is provided that can increase the operation stroke and also the gripping force of a pair of gripping members. The hand includes first and second sliders, a driving source, a rotating plate, a first clamping link. Of these components, the first and second sliders are provided on a hand body so as to be linearly movable in opening and closing directions and the driving source is provided in the hand body. The rotating plate is rotatably driven by the driving source. The first clamping link is linked with the rotating plate so as to be only rotatable on a first shaft, and is linked with the first slider so as to be only rotatable on a second shaft. Moreover, the second clamping link is linked with the rotating plate so as to be only rotatable on a third shaft, and is linked with the second slider so as be only rotatable on a fourth shaft. The first and second sliders move linearly in the opening and closing directions by making the driving source rotate the rotating plate.
