摘要： PURPOSE: To perform a uniform heating process over a wider range with an electromagnetic wave heating device capable of performing heating using the principle that strong field exists at a front position λ/4 apart from a short plate in a waveguide. CONSTITUTION: A plurality of waveguides 1 and 2 with rectangular cross section and each one side closed with a short plate 7 are stacked, so as to keep the long sides of the rectangular form superposed. Also, a nonmetal tube 3 for flowing a heating object is laid through the waveguides 1 and 2 along a direction vertical to a plane including the long sides. Furthermore, the other sides of the waveguides 1 and 2 without any short plate 7 are connected to electromagnetic wave generators 4 and 4 respectively. In this case, a zone M to give maximum field strength is at a position away from the short plate 7 by 1/4 of the waveguide wavelength of the frequency of an applied electromagnetic wave. According to this construction, a plurality of the zones M to give the maximum field strength can be set along a direction across a transport route 3. Thus, the diameter of the tube 3 can be enlarged to increase a process rate and apply uniform heat. In this case, the waveguide may be laid by a plurality of numbers or one waveguide may be branched. Also, uniform heat can be applied over a wider range, when the waveguide is expanded like a tapered form.

When the plate 1 is rotated around the pin 7a, the section 8 comes into contact with the top end section of a side face plate 6 and an action of levers is produced. When the plate 1 is further rotated, the connector 4 of the board 5 is disengaged from a connector 3 and the board 5 starts to come off an enclosure. By moving the handle plate 1 held by a holding section 9a from an arm body 9, the connector 4 of the circuit board 5 is disengaged from the connector 3 and the board 5 is pulled out from the enclosure.

摘要： PURPOSE:To enable adjustment of amplitude of standing wave by arranging an antenna of a large gain toward a wave absorber and by arranging an antenna of a small gain toward an antenna of an antenna mechanism of the other party. CONSTITUTION:An antenna 2a of a large gain is arranged toward a wave absorber 3. An antenna 2b of a small gain is arranged toward an antenna of a receiver antenna mechanism. Transmitted wave is distributed to two systems by a Y-coupler 5. An amount of attenuation of wave of each system is adjusted by each of attenuators 4a, 4b, and wave thereof is projected from each of antennas 2a, 2b. The antenna of the receiver antenna mechanism 2 receives both scattered wave from the wave absorber 3 and direct wave from the antenna 2b simultaneously. The receiver antenna mechanism 2 measures standing wave from received scattered wave and direct wave and calculates an absorption amount. Ratio of the scattered wave to the direct wave is adjusted by attenuators 4a, 4b at the side of the sending antenna mechanism 1.

摘要： PURPOSE:To suppress a scattering wave in a specific direction not equal to an incident angle by irregularly disposing a stripelike conductor film. CONSTITUTION:When the intervals of arrays in a direction (x) in an absorber in which stripelike conductor films 1, 2 are disposed in 2 stages in a direction (z) are w1, w2, a scattering wave is generated by a current flowing on the films and a metal plate, and the angular characteristics of the wave can be approximated even if a regulation system is collapsed hy noting only the scattering wave components from the films 1, 2 by altering the w1, w2. That is, the current flowing on the plate is varied by the influence of the films, and when the regulation system of the array of the films 1, 2 arranged in the direction (z) is collapsed, the current on the plate is collapsed in the regulation system, and uniformly flows approximately.

摘要： PURPOSE:To obtain a large amount of attenuation and to reduce influence on a leakage preventing effect, by arranging electrically conductive barlike conductor parts, and providing planar magnetic members between the neighbor ing parallel conductor parts. CONSTITUTION:Electrically conductive barlike conductor parts 1 are arranged in parallel. Planar magnetic members 2 are provided between the neighboring parallel conductor parts 1. As the magnetic members 2, the following material is used: a planar magnetic material comprising amorphous material, Permalloy, ferrite and the like having high permeability; or a linear magnetic material comprising the same materials. The materials are arranged in a planar state. When the materials are provided between parallel metal plates, the effect of the magnetic material is further added to the cut-off effect as a waveguide. Thus, a large amount of attenuation is obtained, and influence on a leakage preventing effect is reduced.
