Title: Light wavelength multiplexing transmission system and its equipment
Inventor: NAKAMOTO HIROSHI
IPC: H04B10/296
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To detect crosstalk between channels due to the deviation of a light wavelength by detecting high-frequency main signal components, included in an optical signal of a certain wavelength and each signal level of low-frequency control signal components superimposed to this at a fixed rate. SOLUTION: A part of a light wavelength multiplex signal is optically branched to extract the optical signal of a single wavelength by a variable wavelength filter to photoelectrically convert by a detector PD. Among the obtained signals, a high-frequency data signal is separated by a high-pass filter HPF to detect an amplitude level LV1 by a level detecting part LVD1, and the control signal component of low frequency is separated by a low-pass filter LPF to detect an amplitude level LV2 by a level-detecting part LVD2. A crosstalk judging part detects the outputted signal LV1 and LV2.  When a detected superposing ratio becomes smaller than a prescribed ratio, the judging part judges the entering of interfering light and effectively detects the existence of crosstalk to cope speedily with it and to suppress the adverse effects of over/under shoot on an optical transmission line, due to the sudden insertion/ pulling out of the optical signal.

Title: Image display device
Inventor: KUREMATSU KATSUMI
IPC: G02B27/00
Filed: 1989-11-24
Abstract: PURPOSE:To improve the contrast of a display image by arranging a lens part, a light transmitting part and a light shielding part under specific positional relationships. CONSTITUTION:A screen 10 is provided with a horizontal lenticular sheet 11, an eccentric Fresnel lens sheet 12 and a vertical double lenticular sheet 13 in that order, viewed from a light incident side. An original image light alpha made obliquely incident at around an incident angle theta1 is condensed by the lens part of the lenticular sheet 11, passes through a black stripe 11a, and is emitted to an observation side via the Fresnel lens sheet 12 and the vertical lenticular sheet 13. On the other hand, a light beta through internal reflection causing contrast deterioration is condensed by the lens part, impinges on the black stripe 11a arranged in front of the lens part and is absorbed thereby, because its incident angle theta2 on the screen 10 decreases. Thus, image contrast is improved.

Title: 4-phase demodulation circuit
Inventor: OKADA KAZUO
IPC: H04L27/22
Filed: 1989-11-24
Abstract: PURPOSE:To solve a problem such as unstable operation or an error in phase shift in a -90 deg. phase shifter by adopting digital multipliers and LPFs and interposing a D/A converter between a phase detector and a VCO. CONSTITUTION:A QPSK signal inputted to a 4-phase demodulation QPSK input terminal 16 is converted into a digital quantity by an A/D converter 31 and the signal passes through digital multipliers 27, 28 and digital LPFs 29, 30 and is fed to binarizing devices 21, 22 and a phase difference detector 23. The phase difference detector 23 compares the phase of the carrier at the generating side of the QPSK signal and the phase of the recovered carrier generated from a VCO 24 and gives a signal subject to D/A conversion by a D/A converter 32 to the VCO 24 so as to make the difference zero. That is, the VCO 24 receives a converted analog signal and the VCO 24 outputs a rectangular wave, which is substantially a digital signal and fed via a -90 deg. phase shifter 25 or directly to the multipliers 27, 28 and processed digitally. Thus, the operation is made stable and a digital phase shift is generated from the -90 deg. phase shifter to eliminate the error.
