Title: Snow thawing roof
Inventor: MAKIE KICHISABURO
IPC: E04H9/16
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a snow them roof low in an equipment cost and requiring no running cost by continuously arranging a plurality of rows of snow thaw roof plates by bending/continuously molding a wire net or a punching metal plate of an inverted V-shaped cross-section on the upper surface of an inclined roof. SOLUTION: The upper surface of an inclined roof (a) is covered over the whole surface with plural-row snow extinguishing roof plates 1 bent/continuously molded in a cross-sectional inverse V shape. The snow thaw roof plates 1 are constituted of a wire net or a punching metal plate. The base part 1' of these snow thawing roof plates 1 is fixed to the roof surface (a') by an installing metal fitting 2 so as to be freely attachable. Therefore, the contact area of roof snow laid on the snow thawing roof plates 1 with the atmosphere increases to make the snow than action quickly progress. An inclined face rising wind of air warmed by solar radiation in the daytime thaws snow from inside through an opening hole of the wire net or the punching metal plate. Therefore, a snow thaw roof low in an equipment cost and requiring no running cost can be provided.

Title: Laser welding method
Inventor: KONDO YASUO
IPC: B23K26/21
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a blowhole by emitting a laser beam, along a groove line where materials to be welded are abutted on each other, in the inclined manner so that the laser beam is provided with a specific angle of advance or angle of sweep back from a vertical direction against the groove line. SOLUTION: A laser beam 2 outgoing from a laser welding head 20 is emitted along a groove line 3a on the upper edge side in the inclined direction forming an angle of advance α from the vertical direction y. Immediately below the irradiation point of the laser beam 2, a key hole is formed, in the advancing rear side of which a molten area is generated holding a molten state until conversion to a welding layer and is moved forward with a fixed width maintained constantly; however, because of the angle of advance α formed by the laser beam 2, the contour of the molten area becomes a parallelogram tilting backward in the front view.  Bubbles, rising vertically in the molten material by buoyancy, passes through upward to the outside because the solidification of the molten material is delayed in the upper side with the vertical direction as a reference, without remaining in the welding layer as a blowhole.
