<p>PURPOSE:To restrain an electric field between straps from coupling with a ball piece and the cathode, by using an annular, platelike strap and an annular strap whose inner diameter is bent so as to cover this platelike strap and made up into a section L-shaped form. CONSTITUTION:Each annular, platelike or linear strap 140 is fitted in notches 120A and 120B, while an annular strap 150 whose inner diameter is bent into a section L-shaped form is installed so as to cover this strap 140 in on contact. The strap 140 connects anode pieces alternately as in anode pieces 110B, 110D and 110F,... by way of example, while the strap 150 is tightly attached to anode pieces 110A, 110C and so on. Setting of straps 160 and 170 at the lower part comes into a connecting state different from the upper part. Thus, one side strap is constituted so as to be wrapped inside whereby magnetic coupling between an external space and a resonator of the anode is restrainable, so that stable operation is performable.</p> |
