Patent JP-H03175801-A (JP)
Title: Transmission line for blocking dc component
Inventor: KOBAYASHI NORIYUKI
IPC: H05H1/18
Filed: 1989-12-05
Abstract: PURPOSE:To reduce the leakage of a high frequency component to an external part with simple constitution by connecting gaps different in characteristic impedances to conductors in series. CONSTITUTION:The internal gap 13 of an internal conductor 11 is formed by interposing an insulating sheet 5 in the conductor 11. The external gap 14 of an external conductor 12 is constituted by alternately connecting in series the gaps 1 and 3 of the characteristic impedance small due to a narrow gap interval and the gap 2 of the characteristic impedance whose gap interval is large to the external conductor 12. Since the gap intervals of the gaps 1 and 3 are considerably small, insulating withstand voltage can be improved by interposing the insulator sheet 5. Most part of the high frequency component transmitted from a point A along the gap 1 is reflected in a point B, and a part of it passes through the point B, and reaches a point C along the gap 2. Here, the high frequency component is largely reflected and the remaining component passes through the point C and it leaks outside from a gap end 16 through the gap 3.

Title: Pole holding structure
Inventor: KAWAMOTO MASAYUKI
IPC: D06F25/00
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To provide pole holding structure which can easily deal with the adjustment of gap between poles and has sufficient reinforce strength against the lateral force and torsional force of poles. SOLUTION: Bracket members 15a and 15b almost formed in the shape of triangular plates are fitted through screws 29 to respective pole members 11a and 11b. Plural screw holes 25 are formed at upper edge parts 17a and 17b of respective bracket members 15a and 15b. Plural openings 27 are formed on a connecting member 21 whose cross section is U-shaped. After the gap between the pole members 11a and 11b is adjusted corresponding to the width of object to be placed, the connecting member 21 is strongly fitted onto the upper edge parts 17a and 17b of bracket members 15a and 15b by fastening fitting screws 23 through the openings 27 into the screw holes 25. Thus, holding structure is made strong against the lateral force and torsional force applied to the pole members 11a and 11b.
