A method of and apparatus for determining a position of a working original point at which working characteristics of a multi-joint manipulator are at optimum. According to the method and apparatus, a working point at which a hand mounted on the multi-joint manipulator works and a workspace needed for the work are assigned. Subsequently, a set of positions of the working original point of the multi-joint manipulator at which the hand may reach the workspace is calculated. Also, values of evaluation functions representative of preference of the working characteristics of the multi-joint manipulator are calculated with respect to the respective positions of the set. Then, the values of the evaluation functions are compared with each other, thereby selecting the position of the working original point at which the working characteristics are at optimum.

An apparatus performing a filter from a material for a filter element automatically and quickly. The filter made by the present apparatus has a plurality of wavy portions which are provided in such a manner that a plurality of wavy portions forms a circle.The apparatus employs a contracting apparatus for contracting a continuously corrugated strip of material for a filter element in such a manner that a distance between adjacent ridges of the corrugated strip is reduced so that the corrugated strip becomes the wavy portion of the filter. The apparatus also employs a rounding apparatus for rounding the continuously corrugated strip in such a manner that both ends of the strip are connected to each other so that the wavy portions made from the corrugated strip form a circle. The apparatus further employs a shaping apparatus for shaping the rounded continuously corrugated strip so that the rounded strip becomes the filter.

A device for supplying a long length of a material such as a metal strip, wire, thread, and the like, having an accumulator between a material supply source which holds and supplies the material and a feeding mechanism which feeds the material to the following process. The accumulator is provided with first rollers pivotally mounted on a fixed bridge, and second rollers pivotally mounted on a movable bridge. The movable bridge moves up and down relative to the fixed bridge. The material supplied from the supply source is passed alternately over the first rollers and second rollers in such a manner that it is led straight up and down, and is then fed to the feeding mechanism. A controlling mechanism controls the material supply source to feed the material, or to stop the feeding, according to the position of the movable bridge.

A light-emitting device comprises: a substrate that holds one end of connection terminals and on which is mounted an electronic component; a light-emitting element that is mounted on one face of the substrate; a support member on which the substrate is mounted; and a cover section that positionally locates and holds the substrate, by mounting on the support member in a condition abutting one face of the substrate. The cover section has a cover section body that covers one face of the substrate; on the cover section body, a light guide is provided, through which passes the light that is emitted from the light emitting element, in a condition in which movement thereof is restricted along directions on either side of the substrate.

A valve timing controller has a control valve and a linear solenoid. The control valve is disposed in an interlocking rotor constructed by a vane rotor and a camshaft. The linear solenoid includes a movable member having an output shaft, and a bearing portion supporting the movable member to reciprocate and rotate. A spool of the control valve is contact with the output shaft. The output shaft contacts a sphere-shaped end surface of the spool, at a contact position offset in a radial direction from a center axis of the spool.

The torque fluctuation absorber includes a flywheel fixed on a first rotating shaft by a fixation member, a damper unit connected with a second rotating shaft and absorbs fluctuation of torque occurred between the first rotating shaft and the second rotating shaft by elastic force, and a limiter unit provided on a power transmission path between the flywheel and the damper unit and inducing a slide when the fluctuation of the torque exceeded a predetermined value. A predetermined member rotates with the first rotating shaft on a power transmission path between the first rotating shaft and the limiter unit. The predetermined member has a side plate at the damper unit and a guide portion that prevents movement radially of a hub member, and the guide portion is provided at radially internal side of the fixation member.
