Title: Apparatus and method for eliminating echo
Inventor: FUYUN RIN
IPC: H04B3/23
Filed: 1988-07-01
Abstract: PURPOSE: To enable the correction of long distance echo by generating a complex phase correction sample by correcting the phase of an input sequence for the prime sample of a carrier wave modulated based on phase difference to be changed, and generating the simulation of real value of an echo signal. CONSTITUTION: A signal point is sent to a bulk delay simulator 78, and timewise delay related with a distance between the local transmission of the modulated carrier wave and the return of the long distance echo signal is simulated. Concerning the signal point sent by the delay device 78, its phase is controlled by a modulator 80, next, this signal point is inputted to a long distance echo canceler 74, and this canceler generates Ef(k) while using a linear adaptive transversal filter. A phase difference evaluator 82 evaluates phase difference between the real long distance echo and the simulated long distance echo Ef(k) and removes total phase deviation in the input to the echo canceler 74. Thus, the long distance echo canceler can be exercised together with the circuit 82 and a PLL 110 so as to provide optimum performance while being linked.

Title: Microwave tube
Inventor: SATOU HISAAKI
IPC: H01J23/033
Filed: 1983-09-09
Abstract: PURPOSE:To obtain a durable collector by subdividing a radiator radially located outside an annular or conical annular collector core. CONSTITUTION:A radiator is subdivided in the direction of the tube axis and the direction perpendicular to the above direction so as to make the machanical rigidity of the radiator remarkably lower than that of a collector core. For example, the dimension (a) in the circumference direction of each subdivided radiator section is adjusted to be below about 1/2 of the thickness (t) of the collector core while the longitudinal dimension (b) is adjusted to be below about two times the thickness (t). As a result, the concentration of thermal stress is alleviated thereby obtaining a collector for a long-pulse superhigh-power microwave tube having a notably higher durability than the conventional one.

Title: Optical fiber cable
Inventor: YAMANASHI YOSHITSUGU
IPC: G02B6/44
Filed: 1980-11-26
Abstract: PURPOSE:To reduce variations in transmission loss of light due to vibrations of an optical fiber cable resulting from interference of light, by providing uneven refractivity distribution to both end parts of the core of the cable. CONSTITUTION:The intermediate part of an optical fiber cable F has even refractivity distribution, and both end parts Fa and Fb of the core of the cable have uneven distribution, increasing the number of modes of an optical signal at the output terminal of the optical fiber. For the transmission of light from a light source, such as a semiconductor laser, having less distribution of oscillation wavelength and less mode distribution, a simple interference pattern generated at an optical fiber cable connection point is made complicate. Consequently, the complicate interference pattern is generated at the connection point of the fiber cable and even if the optical connection point shifts, variations in transmission loss are reduced.
