  • Patent number: 8093530
    Abstract: A laser cutting apparatus and a laser cutting method are provided which are adapted to concentrate laser light into a silicon substrate to produce a plurality of internal cracks. A light concentrating position, to which laser beams included in the laser light are concentrated, is temporally and spatially displaced to appropriately change lengths of the cracks according to positions in a direction of depth of the substrate. Consequently, the lengths of the internal cracks are controlled to surely lead a crack opening, the starting point of which is the internal crack formed by laser processing, to a predetermined cutting line on a surface of the substrate.

  • Patent number: 8016406
    Abstract: An aqueous ink comprises water, a water-insoluble coloring material, and plurality of water-soluble organic solvents and the plurality of water-soluble organic solvents including a good medium or good mediums for the water-insoluble coloring material and a poor medium or poor mediums for the water-insoluble coloring material. The ratio of the content of the poor medium and the content of the good medium is in a specific range. A water-soluble organic solvent showing the maximum Ka value out of respective Ka values of the plurality of water-soluble organic solvents is the poor medium. When the aqueous ink is in contact with a specific reaction liquid, the dissolution state or dispersed state of the water-insoluble coloring material in the ink is made unstable. As a result, an image which has a sufficiently large area factor even with a small amount of ink droplets and is excellent in image density, bleeding resistance, and fixability can be obtained.
