IPC: H01Q1/32
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To easily control an antenna performance and to simplify a coaxial cable structure by transmitting or receiving a communication signal through capacitance of an electrostatic operating film. SOLUTION: An electrostatic operating film 20 successively laminating other electric conductor layers 21 and 23 through at least one intermediate dielectric layer 22 is formed on a feeding point or conductor layer formed on the feeding point.

Histone is a protein which is combined with a DNA in a nucleus by an ion bond to form a DNA histone complex and contributes to the structural stability of a chromosome DNA. The addition of histone can prevent a nonspecific annealing by maintaining a template in a double strand during heating for denaturation in a PCR. The thermostable histone is obtained by screening a chromosome DNA library of a hyperthermophilic archaebacteria to give a gene, incorporating the gene into a vector and expressing the gene in a host cell.
