Abstract: 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.

Abstract: PURPOSE:To prevent the substantial opening of an opening section for inserting a signal conductor when the opening section is not used, and to inhibit the area of the opening minimally when the signal condoctor is inserted by arraying good conductor small-gage wires in parallel at intervals of several mm or less, larger than the diameter of the small-gage wire, and short-circuiting one side ends of each small-gage wire with sheet-shaped good conductors. CONSTITUTION:Small-gage wires 1 composed of a good conductor are arranged in a row in the same plane, and one end sections thereof are short-circuited by sheet-shaped conductors 2. A metallic wire having large conductivity delta, a material in which a fibrous resin is coated with a metal, carbon fiber, etc., are used as the good conductor small-gage wire 1. The good conductor small-gage wire 1, size of which extends over a range of several dozen mum or several mm practically, is employed, and the size of the small-gage wire

Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To easily evaluate the electric field intensity of such electromagnetic wave radiated from a conduction cable. SOLUTION: An in-phase current energized to a conduction cable 3 which is to be evaluated is measured with a current probe 22, and the output voltage of the current probe 22 is detected with a receiver 23. With a calculation process based on the detection result of the receiver 23 and such characteristics approximate line as set in advance, an estimated value of electric field intensity of such electromagnetic wave radiated from a conduction cable 3 is calculated with a data processing system 24, so no complex simulation is required.

Abstract: PROBLEM TO BE SOLVED: To save fuel, such as thermal power and electric power, to be used and electric power to be applied, to the utmost, and incinerate and dispose efficiently objects to be dehydrated. SOLUTION: A dehydrating container 1 has a large number of moisture passage holes 10 through which moisture contained in objects 3 to be dehydrated passes. Further, the dehydrating bag 1 is formed of a heat-shrinkable material so that the container 1 itself is heat-shrinked, compresses the objects 3 to dehydrate the moisture contained in the objects 3, and releases the moisture to the external side of the dehydrating container 1, before the moisture contained in the objects 3 in the dehydrating container 1 is evaporated, when heated by a heating means.

Abstract: PROBLEM TO BE SOLVED: To provide a device wide in a service frequency band where electromagnetic shielding can be evaluated. SOLUTION: An evaluation device has a waveguide 1 and a wave absorber 2 filled in the waveguide 1. A space part 3 with a width 2d is formed in a center position in a width direction, and the wave absorber 2 are arranged on both sides. The height of the waveguide 1 is made low to half the wavelength or less so as to prevent the generation of a mode with the electromagnetic field changing in a y-direction. The width 2d of the space part 3 to be a waveguide path is limited, and the wave absorber 2 not so large in conductivity is used to reduce reflection at a boundary face between the wave absorber 2 and the space part 3 so as to prevent the generation of an x-direction higher- order mode.

Abstract: PURPOSE: To easily measure current flowing out of an opening of a housing of electric device and to provide data useful for EMC control. CONSTITUTION: A personal computer 5 is used as a controller, and a probe 3 comprises an ammeter 1 for detecting leak current and a two-dimensional position detector 2 which are assembled as a single unit, wherein the two-dimensional position detector 2 uses a mouse connected to the personal computer 5. The ammeter 1 for detecting flow-out current is built into the mouse, and by operating the mouse so that its bottom is in contact with a surface of a metallic housing, both position information and a current value can be obtained, so that intensity can be indicated on a map on a computer screen.
