  • Publication number: 20070007109
    Abstract: A system and a method for feeding a solid into a solid deposition system is described. Solid contained in a hopper is directed into a vibratory bowl. The frequency of the vibrations of the vibratory bowl can be modulated by a feedback system. The solid can then be entrained in a carrier gas which can flow to a distributor for deposition on a substrate.

  • Publication number: 20020171441
    Abstract: A method of accelerated life testing of a solar cell includes directing a high-intensity diode laser light through at least one lens onto a small area of the solar cell continuously for a predetermined period of time to simulate long-term sun exposure. Performance of the solar cell is measured before and after exposure to the laser light so that life expectancy unless long-term sun exposure may be determined.

  • Patent number: 6300593
    Abstract: Apparatus (20) and a method for laser scribing a coated substrate (22) utilizes a rotating polygonal mirror (36) to split a pulsed laser beam (30) in order to provide spaced ablations (34) in a coating (26) on the substrate. The laser pulses are directed through at least one lens (56, 60) and may be passed through fiber optics (62). A laser detector (68) may be used to detect the rotational position of the rotating polygonal mirror (36). A controller (76″, 76′″) allows a second set of scribes to be generated with reference to the first set of scribes.

  • Patent number: 6058740
    Abstract: A deposition system (20) for depositing a material layer on a glass sheet substrate includes a lateral alignment mechanism (28) for laterally aligning glass sheet substrates with an ingress seal (48) of a deposition station (22). The lateral alignment mechanism (28) includes a pair of banks (164, 166) of alignment members (168) spaced laterally with respect to each other along the direction of conveyance. Round alignment surfaces (170) of the alignment members (168) are located above conveyor rolls (96) upstream from the housing of the deposition station and are rotatable about associated vertical axes. A positioner (172) moves one of the banks of alignment members (168) laterally with respect to the direction of conveyance toward the other bank of alignment members to laterally align the glass sheet substrate along the direction of conveyance with the ingress seal assembly (48).
