Filed: 1983-06-13
Abstract: PURPOSE:To detect exactly S/N of a receiving signal without being influenced by the frequency and the level of noise by calculating the S/N basing on the number of times of a receiving signal sampled value of prescribed phase angle exceeds a prescribed value. CONSTITUTION:A sample holding circuit 3 is controlled by a sampling pulse synchronizing with a carrier wave of a loran pulse, and a received loran pulse instantaneous value of a prescribed phase angle is held repeatedly. Subsequently, whether a sample value exceeds a prescribed value or not is decided, and a binary-coding circuit 4 outputs binary digits ''1'', ''0'' in accordance with whether said sample value is above or below the prescribed value. Whenever these binary digits ''1'', ''0'' are outputted, the number of times counters 5, 6 are driven to count, respectively, and S/N is calculated by an S/N operating circuit 10 in accordance with a counted value difference of the correlation to S/N of both the counters 5, 6 by a subtracting circuit 9.

Filed: 1985-05-17
Abstract: PURPOSE:To form various refractive index distributions to a core part and to increase the quantity of optical transmission by spinning a thermosetting resin and using the spun thermosetting resin as the core part. CONSTITUTION:A thermosetting resin monomer 16 and a polymn. initiator are mixed and the mixture is filled into a tank 1, from which the resin monomer 16 is pumped 3 to a capillary 14 disposed in a warm water tank 5. The capillary 14 receives the heat from a heat medium (warm water) 18 in the tank 5 to cure the resin therein in the state of high viscosity. The cured thermosetting resin is discharged from a nozzle 6 when the viscosity of the resin increases to about 1X10<4> poise. The thermosetting resin emerges in the form of yarn from the nozzle 6 to form a fiber 17. The fiber is thereafter heated by a curing part (curing tank) 7 consisting of a heater, etc. and is further cured to form the fiber. The optical fiber is formed if a clad part is provided to such fiber.

Abstract: PURPOSE:To increase a reproduction frequency band and to flatten frequency characteristics by using the fiber of silicon carbide as an essential material, by giving the fiber binding and excipient properties by using the thermosetting resin, and by further pressing it thermally by using thermoplastic resin. CONSTITUTION:Fiber of silicon carbide having a 10mum average diameter is cut to about 5mm. length and after they are dispersed in water uniformly, the water is sucked to form sediment of fiber (1.5g) on a scooping net. In this state, moisture is vapored for drying and then phenol resin is sprayed by up to three times (4.5g) as much as the weight of sediment and dried for adhesion without causing deformation and breaking. In a die, a peeled fiber layer is mounted and a thermally melting polyamide film having 15mum thickness and 175-180 deg.C m.p. is arranged for thermal-pressing at 190-210 deg.C. In this process, the phenol resin is cured completely to increase fiber-to-fiber binding force, and the melted pilyamide resin is packed between fibers to achieve complete filling and the generation of internal loss, thus suppressing the resonance of the diaphragm.

Filed: 1981-07-10
Abstract: PURPOSE:To facilitate the reproduction of a complete 50% duty waveform, by using only the first edge of an output pulse of a circuit which gives a T/2 delay to a pulse input signal having a cycle T. CONSTITUTION:A pulse input signal (a) of a cycle T supplied through an input terminal 1 triggers a D-FF6 which serves as the 1st dividing period by a rise edge to obtain a Q output (b). At the same time, the signal (a) is supplied to a delaying circuit 3 which gives a T/2 delay to the cycle T. Thus a delay signal (c) is obtained. Then a D-FF7 serving as the 2nd dividing period is triggered with a rising edge of the signal (c) to obtain the output (b). Both outputs (b) and (d) are supplied to an exclusive OR gat 4 to secure an exclusive OR. Thus an output (e) is obtained with the same frequency as the signal (a) and a 50% duty waveform.
