An optical fiber terminal fitted with an optical isolator comprises an optical fiber, a ferrule which holds the optical fiber in position, and an optical isolator which includes an optical isolator assembly having at least one magneto-optical element and at least one polarizer and means for applying a magnetic field of less than saturation to the magneto-optical element. The fiber, ferrule, and isolator are disposed close to one another and joined integrally. The optical isolator has a maximum outside diameter not more than twice, preferably substantially equal to, the outside diameter of the ferrule.
摘要:
In transmission or recording of a digital signal by means of digital amplitude and phase modulation, particularly recording into and reproducing the same from the a magnetic recording medium, a digital amplitude/phase modulated signal to be demodulated is commonly affected by the non-linear amplitude characteristics and the effects of unwanted jitter and envelope variation. As the result, the error rate of decoded data will be increased. For compensation, the Viterbi decoding technique is employed with the use of a weighted distance value calculated by multiplying an Euclidean distance between the signal point of a reproduction signal and the datum point of each code by a positive weighting factor which is determined smaller when the code datum point is located further from the origin point of a coordinate system. Accordingly, the weighted distance of each reproduction signal point from its corresponding datum point can approximately be uniform thus ensuring less error decoding in general.

A thermoplastic resin composition is prepared by heat-treating a mixture of a thermoplastic resin substantially containing no olefinic unsaturated carbon-carbon bond and an elastomer having an olefinic unsaturated carbon-carbon bond, dynamically in the presence of a crosslinking agent, characterized in that as said elastomer there is used at least one member selected from the group consisting of styrene-butadiene-styrene block copolymer (SBS), styrene-iosprene-styrene block copolymer (SIS), 1,2-polybutadiene rubber and ethylene-propylene-diene random copolymer (EPDM), and that as said crosslinking agent there is used a dihydroaromatic compound or a polymer thereof.

摘要:
A metal gasket for a cylinder head of an internal combustion engine comprises at least one narrow portion extending between cylinder bores of the cylinder head to be sealed by the gasket, and beads extending along circumferences of the cylinder bores. The adjacent beads extend in opposite directions with respect to the gasket, thereby enabling the adjacent beads to be smoothly and gently connected. Such smoothly connected beads prevent any cracks or permanent deformations in the proximity of the beads from occuring when the gasket is firmly clamped between the cylinder head and an engine body. Restoring faculty of the gasket is not lost after being clamped therebetween, so that the sealing capacity in the proximities of the beads is remarkably improved in comparison with the prior art.
摘要:
An FM signal demodulator has a phase shifter including transversal filters for producing from a FM video signal two FM video signals which are different in phase by 90.degree. from each other, and a demodulator for detecting phase information of the FM video signal, wherein the carrier frequency is at least quadrupled prior to demodulation so as to suppress components of the FM video signal not to be included in the demodulated video signal.
摘要:
A video signal processing apparatus has an input terminal for receiving an input video signal and a delay line for delaying the input video signal. A first transmission circuit processes the video signal which has been delayed by the delay line and a first timer reversal circuit reverses the time sequence of the input video signal during a predetermined time period. A second transmission circuit processes the time reversed signal from the first time reversal circuit and a second time reversal circuit reverses the time sequence of the signal processed by the second transmission circuit. An adder circuit adds the signal processed by the first transmission circuit and the time reversed signal from the second time reversed circuit. A control pulse generator produces a control pulse sequence which inverts its level every predetermined period so as to control the first and second time reversal circuits. The output of the adder circuit serves as the output signal processing apparatus.
