摘要： PURPOSE:To easily draw a circular arc or circle by providing a writing instrument-positioning member having an inserting hole formed to pass a writing instrument therethrough. CONSTITUTION:The center of a circular arc to be actuated by a calibrated cap 12 via a transparent cover 11 and a through hole 8 provided on the rotary axis of a handle 3 is made to align with the rotary axis of the handle 3. Concurrently with this alignment, a writing instrument positioning member 16 is slidably moved along a sliding groove 15 and secured in coincidence with the radius of the circular arc and the handle 3 is rotated while a writing instrument 20 is being located by the writing instrument positioning member 16, thereby drawing a desired circular arc.

摘要： PROBLEM TO BE SOLVED: To provide an oscillating actuator provided at a comparatively low cost by not requiring a very high precision level in machining accuracy and assembly accuracy of parts and causing practically no oil leakages of a working medium such as oil inside and outside an apparatus. SOLUTION: A roller 9 inserted in a circular operation chamber 3 provided in a main body 1 is pressed by feeding the working medium to an operation hose 4 arranged in the operation chamber 3 and fixed by a stopper 6 and expanding it. By this, an oscillating motion is outputted by an oscillating disk 11 fixed to the roller 9.

摘要： PURPOSE:To improve assembling work efficiency and motion performance by connecting elastic structural bodies through plate-shape links, and forming an error correcting structure by the elastic deformation of a groove in its fulcrum part of combination of units or components. CONSTITUTION:Round grooves 1 in a semi-circular shape are formed in horizontal and parallel conditions to each other, and a parallel link is formed from A, B which connect a groove center P point. When a C-surface is fixed and a load is applied in D direction, the parallel link A, B is elastically-deformed with the P point as a fulcrum. When the parallel link A, B which connects the four P points is formed into such a structure so have rigidity against the load D, and surfaces E and C move, kept in a parallel condition by value F. The rigidity, displacement or number of links of the round groove central part is set at a value necessary for error correction. In its upper part, rigidity is set high in the Z and Y directions, and flexibility is set high in an X direction. In a lower part, rigidity is set high in the X direction, and flexibility is set high in the Y direction, so that it is formed into a plate-shaped condition at a position where three axes cross orthogonally, and the round grooves are formed at both the edges in horizontal and parallel conditions. It is thus possible to provide an automatic correcting joint if a positioning error is generated in the X or Y direction.

摘要： PURPOSE:To provide possibility of three-dimensional tracing symmetrical about a plane and safely perform precision processing, measurement, assembly, and transport simultaneously without requiring the time and skillfulness by furnishing a mechanism which can make three-dimensional tracing symmetrically about the reference plane between objects. CONSTITUTION:Two structures 8 movable in the Y-direction are combined with a structure 5 which is movable in the X-direction, and two pulleys 12 having the same outside diameter are fixed to the ends in Y-direction of the X-structure 5 so that the motions of the structures are synchronous and symmetrical to the left and right, wherein the pulleys are restrained by a belt 13 or chain so that their rotating directions and speeds are identical. The belt or chain in its positions point-symmetrical about the center between the pulleys 12 is fixed to the structure 8 movable in the Y-direction, which generates a condition where synchronization symmetrical to the left and right is practicable.

摘要： PURPOSE:To distribute the fluid energy produced by the waves of a liquid formed during the liquid movement and rocking. CONSTITUTION:A plurality of cushioning walls 3 are provided intersecting the moving direction of a liquid L at a predetermined angle to thereby disperse a large wave formed by the movement of a liquid L into smaller waves, thereby minimizing changes in the moving center of the liquid L. Moreover, a cushioning structure 2 is set within a container 1 to prevent the center of gravity of the container 1 from changing.
