摘要： PURPOSE:To obtain relatively large displacement at a point C by constituting a triangle which has three vertical angles A, B, and C, the shortest segment AB, and an almost 180 angle acute angleBAC and expanding the slight expansion/ contraction quantity of an expansible means. CONSTITUTION:The size of a base block 6 corresponding to the triangle is denoted as l1, the size of a piezoelectric element 5 is denoted as l2, and the size of a link 4 is denoted as l3. Here, when the piezoelectric element 5 is applied with a voltage and strained to l2+DELTA1 as shown by an arrow 1, it is assumed that the point C rotates around the point A by theta1 and around the point B by psi1. At this time, an equation I holds for respective parameters. In the initial state, the angle acute angleBAC is nearly 180 deg., so theta1 is found from an equation II on condition that l3=l1+l2. The displacement of the point C, i.e., the device shown by an arrow 2 is found from DELTA=l2sintheta1.

摘要： PURPOSE: To cross action shafts of 2-freedom degree of a frame at one point and reduce the calculation quantity in a coordinate transformation by fixing a U-shaped frame to an intermediate gear engaged with a pair of bevel gears provided in two casings and by providing this frame rotatably to the casings. CONSTITUTION: A pair of bevel gears 2, 3 are arranged in a casing 1 pivotally and rotatably supported by an arm 10 and an intermediate gear 4 engaged with the pair of bevel gears 2, 3 is provided. The bevel gears 2, 3 are rotated in the same direction, the intermediate gear 4 revolves only, and a U-shaped frame 5 fixed to the intermediate gear 4 is moved in the A direction. Secondly, the bevel gears 2, 3 are rotated inversely to each other, the intermediate gear 4 is rotated on its axis and not revolved, and the frame 5 is moved in the B direction. In this case, the action axes in the both A, B directions are 0 and cross with each other at one point. As a result, the calculation quantity can be reduced in the coordinate transformation and the inverse coordinate transformation.

摘要： PURPOSE:To miniaturize the device by arranging two sets of a parallel maintaining mechanism between a moving table and a fixed base, and further biaxial gimbal mechanisms fitted to each of them and expansion mechanisms connected to them, or by arranging at least three sets of the parallel maintaining mechanism. CONSTITUTION:Two sets of a parallel maintaining mechanism 10 are arranged between a moving table 11 and a fixed base 12, and further orthogonal biaxial gimbal mechanisms 9a, 9b fitted to each of them and couplings 7 connected to them for restraining rotation, or at least three sets of the parallel maintaining mechanism 10 are arranged, thus the moving table 11 can be moved in parallel with the fixed base 12 in such a condition that all rotation has been restrained. To actually drive the device, it is so constituted that, for example, three sets of parallel maintaining mechanisms 10, and three sets of a linear drive device 13 whose both ends are rotatably supported are alternately arranged between the moving table 11 and the fixed base 12. Since all of the parallel maintaining mechanisms 10 and the linear drive devices 13 for expanding or contracting the above mechanisms are arranged nearly in one direction, the device can be greatly miniaturized.

摘要： PURPOSE:To avoid an obstacle attached on an overhead line and to smoothly move on a bent overhead line by providing wheels provided with wheel drivers at the tops of supporting brackets, and attaching wheel turning devices to the brackets. CONSTITUTION:Horizontally rotatable turning bases 11, 12 are connected to the front and rear sections of a moving device body 1a. Rocking arms 13a, 13b tiltable in a vertical plane are pivotally supported to the ends of the bases 11, 12, respectively. Supporting brackets 14a-14c are stool on the ends of the arms 13a, 13b and the body 1a, and wheels 15a-15c moving on an overhead line 2 are provided at the tops of the brackets 14a-14c. Wheel turning units 20a-20c for altering the directions of the wheels 15a-15c corresponding to the direction of the line are attached to the brackets 14a-14c. Wheel drivers 16a-16c are provided at the wheels 15a-15c, respectively.

摘要： PURPOSE: To increase a speed and to miniaturize the moving base of a linear motion device used for the manipulator of a robot or the like by arranging a second moving base in a first moving base in a manner that the second base makes a linear motion in the same motion direction as that of the first base. CONSTITUTION: A screw shaft is rotated by the driving of a motor 26, and a first moving base 22 located in the neutral position of a fixed base 21 is moved by 1 in a right direction. By this movement, a second moving base 23 located in the neutral position of the fixed base 21 is pulled by a rope 25a, and by causing a block 24a to act as a running block, the second moving base 23 is moved in a right direction by a distance 21 twice as much as that of the first moving base 22. Thus, since the second moving base 23 is not driven directly by the motor 26, the second moving base 23 is miniaturized without providing any space for passing a screw shaft 27 or the like, and the influence of inertia thereof is reduced. Further, the wide moving ranges of the first and second moving bases 22 and 23 are set.

摘要： PURPOSE: To heighten the adaptability of a robot hand by supporting a pair of fingers by screws for grip action and splines for twist action. CONSTITUTION: A pair of screws 3, 4 are rotated in reverse directions to each other by the rotation of spur gears 7, 8, and a pair of fingers 1, 2 thread- fastened to the screws 3, 4 are brought close to and separated from each other to grip and release a workpiece by the tip parts 1b, 2b of the fingers 1, 2. Spur gears 9, 10 are rotated to rotate splines 5, 6 in reverse directions to each other, and the tip parts 1b, 2b are rotated in reverse directions to each other in relation to the base parts 1a, 2a of the fingers 1, 2 to twist the workpiece. Workpiece grip action and twist action can thus be performed by a pair of fingers 1, 2.
