Title: Optical fiber coupler
Inventor: YAMAUCHI RYOZO
IPC: G02B6/28
Filed: 1988-11-04
Abstract: PURPOSE:To obtain the wide-band optical fiber coupler which is easily manufactured and has low insertion loss by fusing and drawing parts of two optical fibers which are >=15% different in specific refractive index different and thus forming a fusion-drawn part. CONSTITUTION:The two optical fibers 12 and 13 whose specific refractive index differences are >=15% different are fused and drawn to constitute the fusion- drawn part 14, and consequently a difference in propagation constant is generated between the optical fibers 12 and 13. When the relative difference in specific refractive index is >=15%, the optical fibers 12 and 13 are fused and drawn to obtain the practical degree (5-50%) of coupling as a wide-band coupler, but when the specific refractive index difference is <15% relatively, the practical degree of coupling becomes hard to obtain. Consequently, a sufficient propagation constant difference is obtained by equalizing the diameters of the optical fibers 12 and 13 to obtain the wide-band coupler which has the desired degree of coupling.

Title: Filter circuit
Inventor: ETO TORU
IPC: H03H21/00
Filed: 1991-09-30
Abstract: PURPOSE:To effectively evade dot interference even concerning wavy video signals by detecting the signal levels of a synchronizing signal and an inverse phase signal between lines and selectively outputting the output signal of a band pass filter based on the detected result. CONSTITUTION:A filter circuit 14 selectively outputs an output signal S2 of a band pass filter 16 obtained through a delay circuit 18, output signal is S4 and S5 of a two-line interdigital filter, and output signal S31 of a three-line interdigital filter from a selecting circuit 36. When the signal level of the inverse phase signal S4 (S5) is higher than a prescribed reference level and the signal level of an in-phase signal S6 (S7) is lower than the prescribed reference level, the output signal S2 of the band pass filter 16 is selectively outputted. Thus, even when the high frequency component of a wavy luminance signal is large and the signal level of a chroma signal is changed a little between lines or even when the correlation of a line between wavy and continuous lines is low, the dot interference can be prevented.
