Title: Reflector for lighting
Inventor: MATSUSHITA NOBUO
IPC: F21V7/22
Filed: 1988-03-31
Abstract: PURPOSE:To afford an excellent directivity to the reflected light on a white reflecting surface by forming an optical thin film having a refractive index of 1.6 or more in 50-200etam as the optical film thickness on a base plate having a smooth white face. CONSTITUTION:An optical thin film 6 having a refractive index of 1.6 or more is formed with an optical film thickness of 50-200mum on a base plate 5 having a smooth white surface. Although the reflected light reflected by a reflector body 1 is given a directivity by the reflection on the surface of the base plate 5, it is further given the directivity by the interference effect with the optical thin film 6, and the directivity is increased. The reflecting surface never present a dark figure when looked from the directions other than the directing direction of the reflected light. Hence, a high regular reflectance can be obtained by the interference of the optical thin film on the smooth white surface, and the directivity of the reflected light can be increased even on the white smooth surface having the dispersing property of the reflected light.

Title: Demodulator
Inventor: TAKAHASHI HIDEHIRO
IPC: H04L27/00
Filed: 1987-04-02
Abstract: PURPOSE:To attain the demodulation of a signal with a large carrier frequency offset without increasing noise by varying the center frequency of a filter and using carrier frequency offset information in the inside of a demodulator so as to control the center frequency. CONSTITUTION:A filter 1 consists of a variable capacitor 11 and an inductor 12. A demodulator 2 consists of double circuit 23, PLL circuits 24-26, a 1/2 frequency divider circuit 27, a mixer 21 and an LPF 22. Since a VCO control signal in the PLL circuits becomes carrier offset information through the LPF 28, the variable capacitor is controlled by using an epsilonf signal to control the center frequency of the filter. Thus, the center of the band of the filter is made variable in this way, the noise component is reduced and the detection of the carrier frequency offset(error) is attained and the demodulator can trace the error.

Filed: 1994-03-26
Abstract: PURPOSE:To provide transmission type optical integrated circuit and optical pickup capable of precisely efficiently detecting light in the same waveguide mode and suitable for miniaturization, lightening, cost reduction and packaging and with an excellent mass-productivity. CONSTITUTION:An incident luminous flux 22 is led into a waveguide layer 12 by grating couplers 14A, 14B, and becomes waveguide beams 24A, 24B whose polarizing directions intersect orthogonally with each other in the same waveguide mode. The polarization separated waveguide beams 24A, 24B are converged on waveguide end surfaces by waveguide lenses 16A, 16B, and are photoelectric converted by photodetectors 18A, 18B to become electric signals respectively. When the polarizing directions of the incident luminous flux 22 are rotated, the intensity of the waveguide beams 24A, 24B whose polarizing directions intersect orthogonally with each other are changed in opposite phase. Thus, when a difference signal RFDEF between both signals is obtained by an operation part 20, the polarizing rotation of the incident luminous flux 22 is detected excellently as the electric signal.
