The embodiments contemplate a printed circuit board of at least two layers for providing remote wireless communication between a wireless device and a unit, as well as methods of creating an omni-directional radiation pattern for transmittingreceiving information using a notch antenna formed in the printed circuit board having radio frequency circuitry. In each picture element region, a first electrode provided on the first substrate on the side of the liquid crystal layer has a solid portion formed of a conductive film and a non-solid portion with no conductive film provided. The impact arm may be an impact spoon formed on an impact disc. Materials from which individual wires are formed in one embodiment are one of stainless steel, copper or copper alloy. When the in-plane uniformity is judged to be satisfied, the control part 50 regulates temperatures of heaters 11 to 15 by the same procedure so as to satisfy an inter-plane uniformity. The foamed elastic layer is composed of a thermosetting elastomer composition containing 100 parts by mass of a rubber component and 5 to 60 parts by mass of zinc methacrylate or 5 to 60 parts by mass of a mixture of methacrylic acid and zinc oxide as a filler.
