Abstract: PURPOSE:To decrease the length of an inner conductor and to attain the miniaturization of a high frequency filter, by providing a corrugated groove to the inner conductor in the direction of the circumference and with a pitch space shorter than the wavelength secured in the axial direction. CONSTITUTION:A corrugated groove 8 is provided continuously in the direction of the circumference of an inner conductor 2 and arrayed in the axial direction of the conductor 2 at a pitch space shorter than the wavelength.

Title: Line switching system
Inventor: OKAMOTO TSUKASA
IPC: H04L1/20
Filed: 1990-02-02
Abstract: PURPOSE:To maintain the quality recognizing a code error even in any state of the code error by judging the quality of the code error of a line and switching the line by means of the number of accumulation for ES within time being the object of evaluation for the quality of the code error and the number of generation for ES in a time block shorter than observation time. CONSTITUTION:An ES judgement circuit 2 decides whether the code error of the line detected in a code error detection circuit is the previously set code error time ES or not by an inputted code error supervisory signal (a). A counter 3 divides the time being the object of evaluation into blocks, counts the number of generation for ES in respective blocks and it is reset in the block unit. A counter 4 accumulates ES for time being the object of evaluation for the quality of the code error, counts the number of generation for accumulated code error time and it is reset in observation time unit. A clock length operation circuit 6 sets a block length so that it can be decided that ES within time being the object of evaluation exceeds a quality requirement value or not based on the number of generation for the accumulated code error time. When the set block length goes to zero or negative, a switching command signal (j) is outputted to a switching command generation circuit 7 and the line is switched from an active one to a reserved one.
