摘要： Power assist control capable of responding to feeling and sensibility when a man applies force to an object is performed. The power assist control outputs an assist force F or a speed F on the basis of an assist target force X detected by a force sensor 114 for detecting force applied to the object. The relationship between the assist target force X and the assist force F or the speed F to be outputted is F∝f(X) on the basis of a function f(X) having the assist target force X as a variable. The function f(X) is assumed to be a non-linear function which is an increasing function and whose derivative f′(X) is a decreasing function. The function f(X) is a (1/n)-th order function or a logarithmic function. Moreover, a function fup(X) when the assist target force X is increased is different from a function fdown(X) when the assist target force X is decreased.

摘要： Provided is a motion guide device having a scooping portion that is not damaged even when a moving member is moved at high speed.When seen in an axial direction of a track shaft 1, a direction change path 10 is inclined relative to a contact angle line L1 (line connecting a center C of a ball 3 and a bottom P1 of a ball rolling groove 1a). The direction change path 10 including a scooping portion 17 has a cross section of Gothic arch groove shape formed of two arcs R1 in such a manner that the ball 3 is in contact with the direction change path 10 at two points. The direction change path 10 is twisted in such a manner that a locus 18 of the top of the Gothic arch groove shape approaches the contact angle line L1 at the scooping portion 17.

摘要： Provided is a linear and rotary actuator capable of bearing moment and load from a movable body and downsizing its radial dimension. A spline shaft is held in housings to be movable linearly in the axial direction and rotatable about the axis. The spline shaft is connected to a mover shaft of a linear motor. The spline shaft is surrounded with a hollow rotor of a rotary motor. The rotor is connected to a spline nut which transmits rotation of the rotor to the spline shaft by rotating together with the rotor and allows linear movement of the spline shaft. The rotor of the rotary motor is rotated by a stator of the rotary motor. The spline nut, the stator of the rotary motor and a stator of the linear motor are arranged in this order from an end of the spline shaft and mover shaft along the axial direction.

摘要： At both sides of a pair of doors 10L, 10R, a pair of television cameras (two-dimensional image sensors) 18A, 18B for detecting a moving object, and a pair of spare infrared ray sensors 20A, 20B are provided. A central control unit 16 calculates the position and moving direction of moving object by image processing of outputs of television cameras 18A, 18B, and predicts the passing position of moving object on the vertical plane P when the moving object approaches, thereby calculating the target opening degree of a pair of doors 10L, 10R individually, and determines the target opening degree of doors in full closing when the moving object leaves away, and thus outputs move command signals to motor controllers 14L, 14R so that the pair of doors 10L, 10R may be set at the target opening degree.
