  • Publication number: 20190198326
    Abstract: A laser irradiation apparatus (1) according to one embodiment includes a laser generating device (14) that generates a laser beam, a flotation unit (10) that causes a workpiece (16) that is to be irradiated with the laser beam to float, and a conveying unit (11) that conveys the floating workpiece (16). The conveying unit (11) conveys the workpiece (16) with the conveying unit (11) holding the workpiece (16) at a position where the conveying unit (11) does not overlap an irradiation position (15) of the laser beam. The laser irradiation apparatus (1) according to one embodiment makes it possible to suppress uneven irradiation with a laser beam.

  • Publication number: 20190193200
    Abstract: A laser irradiation apparatus (1) according to one embodiment irradiates a workpiece (16) with a laser beam (15) while conveying the workpiece (16) caused to float with the use of a flotation unit (10). The flotation unit (10) includes precision float regions (11a, 11b) and rough float regions (13a to 13j). The precision float regions (11a, 11b) are configured to cause the workpiece (16) to float by utilizing ejection and suction of a gas, and the rough float regions are configured to cause the workpiece (16) to float by utilizing ejection of a gas without suction of a gas.

  • Publication number: 20040054667
    Abstract: A control unit 9 examines the update status of each Web site 11 which are stored as bookmarks in a URL memory 6, the congestion status of a network 2, and the congestion status of a network server apparatus 13 of a user's provider and the like. The control unit 9, based on this examination result, arranges an object corresponding to that Web site by changing the distance (depth) from the viewpoint in accordance with the response of the Web site 11, and displays by changing the height of the object according to the update status. Furthermore, the control unit 9 displays by changing the patterns of each object in accordance with the congestion status of the Web site which corresponds to that object, and displays by changing the weather of virtual space in accordance with the busy status of the network 2. This allows image display of the update status of the Web site to which a bookmark is attached, and the congestion status of the network and the like by using predetermined objects.
