    摘要： Disclosed are a transmission system and a device of small scale, low cost and low power for transmitting signal of a rate over 1Gbps using a small scale and low loss ultrawide band pass filter (UWBPF). The transmission system comprises the steps of generating pulse signal by a short pulse generator, band-limiting the pulse signal by passing it through a waveshape forming filter, and transmitting the resulting pulse signal in a certain frequency band through a UWBPF, and receiving and passing the signal wave through a UWBPF of the same frequency range and introducing the signal wave through a pulse detector into the determining part. The UWBPF used is prepared by forming a distribution constant circuit on a lossy substrate having low-pass function.

    摘要： The present invention relates to an RFeB-based magnet in which a treatment (grain boundary diffusion treatment) for diffusing atoms of the heavy rare earth element R H is performed in a base material including an R L FeB-based sintered magnet obtained by subjecting crystal grains in a raw-material powder including a powder of an R L FeB-based alloy containing the light rare earth element R L , Fe and B to orientation in a magnetic field and then sintering the oriented raw-material powder, or an R L FeB-based hot-deformed magnet obtained by subjecting the same raw-material powder to hot pressing and then to hot deforming to thereby orient the crystal grains in the raw-material powder, and a method for producing the RFeB-based magnet.
