Patent number: 8288678Abstract: A device for maintaining a cutting edge, e.g. a focused laser beam at a constant distance from a surface of the work piece as the cutting edge imposes a cut line in a coating on the surface of the work piece. The device includes a constant force spring connecting a tube to a support and a surface follower mounting an end of the tube. The positions of a surface of the surface follower and the cutting edge have a predetermined relationship to one another. Gas moving out of the tube provides a first gas bearing between the surface follower and inner surface of the tube, and gas moving through passageways in the surface follower provide a second gas bearing between the surface of the surface follower and a surface of the coating. The thicknesses of the bearings remain constant as the follower moves over the surface of the piece to maintain the cutting edge at a constant distance from the surface of the coating.Type: GrantFiled: April 30, 2009Date of Patent: October 16, 2012Assignee: PPG Industries Ohio, Inc.Inventor: Micheal J. Brandt

Patent number: 8283596Abstract: A laser processing apparatus is provided for patterning with laser light a resin film or a metal film formed on a substrate. The apparatus includes a laser light source; and a debris collection device having a transmission window through which the laser light is transmitted, a vortex generation mechanism generating a vortex gas flow by allowing gas to flow into a region near a laser light-irradiated area of the resin film or the metal film, and a screening device having an opening through which the incident laser light passes and screening a flow of debris. The mechanism is placed close to the resin film or the metal film on the substrate. Debris generated by laser light irradiation and before and after being stacked on the object film is entrained in the vortex gas flow generated by the vortex generation mechanism and is exhausted to outside through the screening device.Type: GrantFiled: June 12, 2008Date of Patent: October 9, 2012Assignee: Sony CorporationInventors: Hidehisa Murase, Yoshinari Sasaki, Kosei Aso, Naoki Yamada

Patent number: 8278592Abstract: While six rows of molten processed regions 131, 132 to become a cutting start point are formed within a silicon wafer 11 along a line to cut 5, a weakened region 18 is formed in a rear face 21 of an object to be processed 1 along the line to cut 5 when forming the molten processed region 131 closest to the rear face 21. Since the molten processed regions 131, 132 are thus formed within the silicon wafer 11, particles can be prevented from occurring from the molten processed regions 131, 132. Also, since the weakened region 18 having a predetermined depth is formed on the rear face 21 of the object 1 along the line to cut 5, the object 1 can be cut along the line to cut 5 with a relatively small external force.Type: GrantFiled: September 13, 2007Date of Patent: October 2, 2012Assignee: Hamamatsu Photonics K.K.Inventor: Takeshi Sakamoto
