Abstract: A robot hand includes a gripping mechanism. The gripping mechanism includes a pair of gripping claws that perform opening and closing operations in a horizontal direction intersecting with an extending direction of an electric wire. The gripping claw has a lower claw portion that functions as a scooping claw by moving obliquely upward from below. Before or during a bundling operation, a control device of a robot causes the lower claw portion of the gripping claw to move obliquely upward from below to scoop up all electric wires to be bundled.

Abstract: Provided is a control device for a laser machining apparatus which can maintain the inclination direction of a nozzle with respect to a machining program route even during modification of the tool diameter correction amount, and which can improve machining accuracy.

Abstract: The present invention provides a method for manufacturing zinc oxide whiskers, whereby zinc powders composed of particles coated with an oxide film, preferably an oxide film having a superior sealing property are, heated for oxidization in an atmosphere containing oxygen.The atmosphere may contain carbon dioxide or steam.The obtained zinc oxide whiskers are formed in a single crystal comprised of a core part and an acicular part spreading in four different directions from the core part.For a baking furnace to obtain zinc oxide whiskers, is employed one that successively forms an atmosphere of a high partial pressure of zinc steam at the source side and an atmosphere of a high partial pressure of oxygen for facilitating formation of whiskers. The zinc oxide whiskers can be controlled in size by selecting the relative ratio of the partial pressure of zinc steam and oxygen.

Abstract: Disclosed is a rubber modified styrene resin composition which comprises 50-98% by weight of a rubber modified styrene resin and 50-2% by weight of zinc oxide whiskers. This composition can provide molded articles excellent in mechanical strength, surface state and vibration damping characteristics. Impact strength can be further improved by adding to the above composition a rubber-like material. The zinc oxide whiskers preferably have a tetrapod-formed crystal structure and furthermore, is preferably surface treated with a coupling agent such as silane compound.

Abstract: Disclosed is a polypropylene resin composition which is superior in mechanical strength and affords molded articles having good appearance which comprises (A) a crystalline polypropylene, (B) a polypropylene modified with an unsaturated carboxylic acid or an acid anhydride thereof, and (C) a zinc oxide whiskers. When the composition additionally contains an inorganic filler such as glass fibers, molded articles further improved in appearance can be obtained. The zinc oxide whiskers preferably have a tetrapod type crystal structure.

Abstract: A sliding resin composition comprising an aromatic polycarbonate resin composition (A) and zinc oxide whiskers (B) in an amount of from 1 to 40% by weight based on the total weight of the sliding resin composition. The sliding resin composition is suitably used in fields where a sliding property is required, such as a lens frame (lens tube) for cameras, gears and cams for OA machines and apparatus, etc.
