  • Magnet biased work tool
    Patent number: 7536791
    Abstract: A work tool according to the invention is configured in such a manner that when an operator performs a predetermined operation by gripping a gripping section and opening/closing an active section, the opening and closing operation can be achieved smoothly without employing a spring by gripping the gripping section strongly and releasing the same because a repulsive force of magnets urges two pressure-nipping members in the direction in which the gripping section opens.
    Type: Grant

  • Process for ultraviolet curing
    Patent number: 5732477
    Abstract: The disclosed invention is an ultraviolet curing process that causes a wrinkle pattern to appear on the surface of a curing layer. Initially, the primary stage of the process is generated by irradiating a photopolymerizable layer with far ultraviolet light wherein the dominant wavelength emitted is 254 nanometers. Then, the second stage of the process is performed by heating the photopolymerizable layer. Finally, the third stage of the process irradiates the layer with high pressure vapor ultraviolet light.
