Title: Receiving device
Inventor: SATO TAKASHI
IPC: H04L25/38
Filed: 1984-11-21
Abstract: PURPOSE:To obtain a receiving device with simple circuit which is able to receive the transmitted data accurately and is stable against frequency variation and noise by making the system to receive a pulse signal that expresses the binary data by the variation of pulse spacing. CONSTITUTION:The demodulation signal (a) of a demodulating circuit 5 is constituted by the synchronizing signal of comparatively long pulse spacing and the 8-bit data that follows the synchronizing signal and expresses the binary data with its varied pulse spacing. And, the synchronizing signal of which pulse spacing is longer than that of the data pulse by n-times of it, is detected. Based on the pulse spacing of this synchronizing signal, a space which is longer than 1/n(m>n) of this pulse spacing is made '1' (or '0'), one that is shorter than the 1/n length is made '0' (or '1'), by which signal the system performs its decision, and obtains a binary data of specified number of bits.

Title: Controlling method for switching operation of ac autorange circuit
Inventor: KUDO MAKOTO
IPC: G01R15/08
Filed: 1991-08-29
Abstract: PURPOSE:To set a proper range quickly for a waveform distortion or the like by a method wherein two, high and low, amplitude monitoring circuits are arranged and an effective value of an input signal is controlled within a certain reference value of a fullscale voltage to switch the range. CONSTITUTION:For example, when an effective value of an input signal voltage is larger than a fullscale voltage of the current range in a range switching circuit 1, a control section 9 switches the current range automatically to an upper range until the effective value enters a range below the fullscale voltage value from a value exceeding 40% of the fullscale voltage. In addition, when a peak value of the input signal voltage exceeds a monitoring voltage of a high level amplitude monitoring circuit 7 because of a waveform distortion thereof, the control section 9 receives a warning signal to be generated from the circuit 7 to switch the current range to an upper range until the signal disappears. By the contrary, when the effective value is below the 40% of the fullscale voltage value, the control section 9 switches the range automatically to the lower range.

Title: Measurement of dispersing characteristics of optical fiber
Inventor: FUJISE MASAYUKI
IPC: G02B6/00
Filed: 1983-12-28
Abstract: PURPOSE:To eliminate an error caused by the elongation of an optical fiber, by calculating a relative group delay characteristic by passing a reference light signal fixed in a wavelength and a measuring light signal variable in a wavelength through the same optical fiber. CONSTITUTION:Two light signals to be modulated with wavelengths lambdak, lambdac, respectively emitted from a modulation applied variable wavelength light source 2 and a fixed wavelength light source 9 are simultaneously passed through an optical fiber 5 to be measured through a synthesizer 10. The emitted light from the optical fiber 5 is separated by a light splitter 11 and separated lights are respectively converted to electric signals by photoelectric converters 6, 7. Subsequently, by detecting the phase difference of modulated signals contained in two lights to be modulated with wavelengths lambdak, lambdac by a phase comparator 8, various relative group delay times of light with the wavelength of lambdak to light with the reference wavelength lambdac are calculated. Further, a light dispersing characteristic is obtained from these delay times. By this method, a time for measuring one relative delay time is made short and, therefore, an error due to the elongation of a fiber with the change in a temp. can be neglected.

IPC: G01N29/11
Filed: 1984-11-19
Abstract: PURPOSE:To judge on the presence of a defect accurately, by a method wherein four probes perform transmissions sequentially while the associated reflection and transmission are received with corresponding probes and a computation is done to divide the product of resulting four reflection sound pressures by that of four transmission sound pressures. CONSTITUTION:Four uniform ultrasonic probes A-D are arranged for a tube 1 to be measured. These probes are so set beforehand that an ultrasonic wave passes radially and circumferentially through the center of the thickness of a tube 1 while reflecting from an internal defect O of the tube 1 by two probe reflection and two probe transmission. Then, when one probe, for example, the probe A, is used as transmitting probe to transmit an ultrasonic wave, the probe B corresponding thereto is used as receiving probe to receiving the reflection thereof from the defect O and moreover, the probe C is used as receiving probe to receives transmission thereof through the defect O. A computation is done to divide the product of four reflection sound pressures thus obtained by that of four transmission sound pressures. From the results of the computation, the presence of a defect can be always judged by a fixed threshold.

Title: Noise reduction system of semiconductor laser oscillator
Inventor: CHIKAMA TERUMI
IPC: H01S5/068
Filed: 1984-11-20
Abstract: PURPOSE:To stabilize S/N value of a laser oscillator by modulating the phase of a feedback light at random or modulating by a high frequency signal at high speed to always vary the phase of the feedback light, and dispersing and averaging noise energy of a laser oscillator generated by reflected light in a frequency manner. CONSTITUTION:The light emitted from a semiconductor 1 is focused by a lens 4, phase-modulated by a phase modulator 2, refocused by a lens 4, and then incident to the end of an optical fiber 3 after refocusing. If the light is reflected on the incident end of the light of the fiber 3, the surface of an optical system lens 4, the reflected light is fed back as the near end reflection to the oscillator 1, and when the feedback light phase becomes special value, the oscillator 1 generates strong noise. However, since forcible phase variation can be applied to the feedback light by the modulator 2, if the phase is varied by the high frequency signal 5, noise frequency can be shifted to high frequency side to eliminate the strong noise in a signal band.

Abstract: PURPOSE: To quickly and exactly extract a frequency hopping wave by a simple processing even if noise and various kinds of communication waves coexist in actual space. CONSTITUTION: A high speed sweeping receiver 5 repeats the sweeping of a preliminarily designated frequency range a prescribed number of times. The only number of times of reception of effective radio waves in which noise, etc., is eliminated by a threshold comparator 7 of the radio waves received by the high speed sweeping receiver 5 during all the sweeping periods is counted and stored by the counter 81a to 81n corresponding to a signal extraction circuit 8 for every chip channel f1 to fn .
