In an antenna that has high sensitivity to frequencies of narrow bands and over a wide band and that can be small-sized, and in a wireless module, wireless unit and wireless apparatus using this antenna, the antenna is comprised of a transmission line, and variable capacitance means connected to this transmission line, and the variable capacitance means controls the resonant frequency. The two jackets are then formed with a first seal sealed around their peripheries to form a lubricating pack having a laminating construction. Polishing repairs the surface and continues to remove an additional amount of the substrate material. An end of a conduit is positioned in the space and compresses the insert when the compressive load on the prop exceeds the compressive load capacity of the insert. The methods include the step of applying a mixed peroxycarboxylic acid composition to poultry. The mixing blade is subjected to an axial thrust which keeps the scraper fin pressed elastically at least on part of the bottom of the inner container.
