Title: Two-dimensional optical deflector
Inventor: YAMASHITA MAKI
IPC: G02F1/01
Filed: 1982-01-20
Abstract: PURPOSE:To increase the deflection angle of an optical beam, by changing the heating temperature of an electric heating unit to change the refractive index of a thin film optical waveguide near an exit end face and deflecting the optical beam, which is emitted from the exit end face, in the direction vertical to the surface of the thin film optical waveguide. CONSTITUTION:When comb-shaped electrodes 3 are driven with a certain frequency (f), surface acoustic waves SAW of a wavelength are generated on a thin film optical waveguide 2, and the refractive index is changed at a periodic pitch in the optical waveguide 2, and an optical beam P1 of the wavelength which is incident at an angle theta to the wave guide surface becomes a Bragg-diffracted optical beam P2 reflected by the wave surface if the condition of an expression Iis satisfied. When the driving frequency (f) for comb-shaped electrodes 3 is changed to f+ or -DELTAf, the advance direction of the Bragg-diffracted optical beam P2 is changed in a range of an angle DELTAtheta. That is, the oscillation frequency of a high frequency oscillator 7 is changed continuously to change continuously the advance direction of the optical beam P2.

Title: Multi-path disturbance detector in receiver for frequency modulation system
Inventor: SUGAWARA HIDEJI
IPC: H04H40/72
Filed: 1985-01-21
Abstract: PURPOSE:To detect multi-path disturbance by extracting a side spectrum component and comparing and detecting that the component is a reference value or over. CONSTITUTION:When a composite signal S1 after FM detection is inputted after multi-path disturbance is generated, an unnecessary high frequency component is eliminated by a low-pass filter 2, inputted to a band pass filter 3, and a pilot signal and a side spectrum component in the vicinity are extracted and amplified (4), and the result is inputted to a band pass filter 5, at which the pilot signal component is attenuated. An output signal S3 via the filter circuit 5 has a waveform in which distortion including much side spectrum components is emphasized. In selecting properly the attenuation of the band stop filter 5, the leading edge of the waveform of the distortion component is made steep to improve the response at generation of multi-path disturbance.
