Title:
MAGNETRON AND MICROWAVE-USING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2013/084497
Kind Code:
A1
Abstract:
This magnetron (1) is provided with: a positive electrode cylindrical body (112) having a high-frequency output unit (111); a permanent magnet (122) provided to both ends of the positive electrode cylindrical body; and a magnetic yoke (121) for housing the positive electrode cylindrical body and the permanent magnet in the interior. A plurality of cut-and-raised portions (1213) are provided on the high-frequency output side of the magnetic yoke, and a metal plate (125) that fits with the high-frequency output unit and the cut-and-raised portions is installed between the permanent magnet and the magnetic yoke, whereby the positive electrode cylindrical body and the magnetic yoke are immobilized relative to each other. It is thereby possible to securely immobilize the high-frequency output unit of a magnetron relative to a wave guide part of a magnetic yoke, microwave-using equipment, or the like without complicating the structure and the assembly method.
