    • PURPOSE:To secure an easy matching even with a big change of the antenna capacity with installation of the arrester circuit as well as the vertical attachment of both the radiation element of 3/4 wavelength and the matching element of 1/4 wavelength onto the metal basement to be earthed. CONSTITUTION:Both radiation element 29 of 3/4 wavelength and matching element 34 of 1/4 wavelength formed with the metal pipe of an appropriate diameter are attached vertically onto earthed metal basement 30 with a constant parallel space kept between the two elements. At the same time, feed matching element 31 and 34 formed by the metal pipe are attached to basement 30 via insulator 32 and a parallel space secured between. Furthermore, element 34 is attached to circular arc type slit 33 centering on element 29 formed on basement 30 via nut 35 in such way that the space can be adjusted to element 31. In such constitution, the steady non- directive radiation of the vertically polarization is obtained at the area of 1/2 wavelength of element 29. In addition, the degree of lightning arrest is increased since element 29 and 34 can be attached directly onto basement 30.

    • PURPOSE:To easily open a new bag by providing nonslips on the tying part of a shopping and trash bag. CONSTITUTION:Nonslips 4 are provided at the tying parts 5 of the shopping and trash bags of polyethylene, etc. used in a large amount at a supermarket, etc. Specifically, the nonslips 4 are applied over both the side edges of the two tying parts 5 in close contact in such a manner as to bring the bulb of a finger at the first joint into contact with the nonslips from both the sides of the tying parts. When the two nonslip parts of the tying parts are rubbed against each other with the fingers, the two tying parts in close contact are slided apart in opposite directions, so that the bag can be easily opened. Concerning the formation of the nonslip 4, its thin layer is attached to the tying parts 5 via an adhesive agent of a thin layer or the tying parts are sprayed with a rapid cure nonslip agent. In this way even the mouth of the shopping or trash bag of the material high in adsorptivity and superthin in thickness can be easily opened by anybody without being moistened with a wet towel or being licked.

    • PURPOSE:To obtain an antenna device whose beam widths not only in a horizontal direction but also in a vertical direction are large and which is small-sized and light in weight by providing a waveguide body and a matching conductor. CONSTITUTION:When a waveguide body 5 is located in the almost spherical electric field formed by a dielectric quarter wavelength excitation antenna ANT, high frequency current is flowed to the inner peripheral surface of the waveguide body 5. The high frequency current is flowed also to the outer peripheral surface of the waveguide body 5, an electric field is generated in a right angle direction to the magnetic field generated on an outer peripheral surface and the electric field is radiated as an electromagnetic wave. The part of the electric field is reflected by the inner peripheral surface, resonance energy is increased by concentrating on the antenna and the electric field itself generated from the antenna is intensified. Further, a radiation electric field is enlarged to the whole vertical direction and a vertical radiation pattern becomes a cocoon shape. A conductor 6 which is electrically connected with the waveguide body 5 and extending in the opposite direction to the antenna and in parallel with a power feeding body 1 is provided, the unbalance of the flouing of high frequency current is eliminated and the antenna ANT is made to be matched.
