Title: Snow melting device
Inventor: YURA MASAKI
IPC: E01C11/26
Filed: 2001-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a snow melting device capable of being installed by a simple installation method and having excellent durability. SOLUTION: A panel support member 3, which reduces a step between the outer edge section of a snow melting panel 2 heated by a heating means generating a snow melting heat quantity and its installation face, is arranged at the outer edge section, thereby the panel support member 3 can simply fix the snow melting panel 2 to the outer edge section at an existing parking garage or an approach to a vestibule or the like. Since the step between the snow melting panel 2 and its installation face 7 is reduced, external force applied to the snow melting panel by the transit and stop of a passenger car or strong wind is reduced, and excellent endurance strength is attained. When the snow melting heat quantity is fed by the heating means at a snowfall, the temperature of the snow melting panel 2 quickly rises, and snow is melted in a short time.  The energy saving type snow melting device 1 realizing excellent snow melting performance with small energy consumption can be provided.

Title: Manufacturing method of corrugated plate for catalyst support
Inventor: YOKOYAMA NAOKI
IPC: B21D13/02
Filed: 2001-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a corrugated plate without generating a scratch or crack and of a corrugated plate without generating a chink when the corrugated plate is led into a pipe. SOLUTION: This manufacturing method consists of a central corrugation part forming process, forming a central corrugation part at the center of a flat plate, and a side corrugation part forming process, forming side corrugation parts at both ends in a state of holding the central corrugation part. As the side corrugation parts at both ends are formed in the state of holding the central corrugation part at the side corrugation parts after the central corrugation part forming process, no material supply shortage to a mold is generated and no scratch nor crack is generated.  Another manufacturing method consists of a rough corrugated plate forming process, forming a rough corrugated plate, and a correction process, correcting the rough corrugated plate by inserting a bar-shaped core into the concavity of the corrugated plate and giving a pressure to the same direction of the corrugation part in a state of the core inserted. Thus, the radius-shaped corrugation part is not collapsed and no openings are generated when the core is inserted into the pipe by pressing.
