Patent JP-S6120903-A (JP)
Title: Visibility improving device
Inventor: ABE YUUICHI
IPC: G02B27/00
Filed: 1984-07-09
Abstract: PURPOSE:To improve the forward visibility by limiting the wavelength of the irradiated light emitted from a car provided with a visibility improving device to a specific wavelength band and recognizing visually the irradiated area through a filter, through which only said wavelength band passes, to prevent dazzle due to the irradiated light from a car running in the opposite direction. CONSTITUTION:When a pedestrian 18 or the like is irradiated by an irradiated light 17A which is emitted from a car 10A provided with this device through a lamp cover 15A through which only the light of a specific wavelength band passes, a driver of the car 10A recognizes visually the pedestrian surely through a filter 19A through which only the light of the same wavelength band as the lamp cover 15A passes. Though an irradiated light 13B emitted from a car 10B running in the opposite direction has wavelength components of a wide range, the driver of the car 10A does not dazzle because the light having wavelength other than the specific wavelength band is intercepted by the filter 19A. Thus, dazzle due to the irradiated light from the car running in the opposite direction is prevented, and irradiated objects are surely recognized visually.

Title: Interference wave eliminating device
Inventor: TSUJIMOTO ICHIRO
IPC: H04B1/10
Filed: 1990-05-31
Abstract: PURPOSE:To effectively eliminate both of the multipath distortion and an interference wave by extracting an interference component without filtering on the frequency base by subtraction of a desired signal replica from a reception signal and weighting the extracted interference wave so that the error signal of a discrimination feedback equalizer is minimum and subtracting the interference component from the reception signal. CONSTITUTION:A discrimination feedback equalizer 2 eliminates the multipath distortion included in a matched signal outputted from a matching filter 1 to generate a discrimination signal and an error signal of the discrimination result. A convoluter 3 convolutes an inference impulse response to the discrimination signal to obtain an inferred desired signal. A delay element 6 fixedly delays the reception signal, and a subtractor 8 takes the difference between the output signal of this element 6 and the inferred desired signal to extract an interference wave component. A correlator 5 takes correlations of the interference wave component and the error signal to obtain a correlation value, and a multipler 4 multiplies the interference wave component by the correlation value to obtain an ingerred interference wave. Thus, both of the multipath distortion and the interference wave are effectively eliminated.

Filed: 1978-11-17
Abstract: PURPOSE:To secure designation for the optional bit number and the output area in a simple constitution in that each step is formed with the logic sum circuit and FF. CONSTITUTION:With application of the high-level control signal to control terminals C1, C2, Cj, etc., the output reverses for selected logic sum circuits 111, 112, 1ij, etc. And JKFF211 which is set by the high-level output given via inverter 411 and OR circuit 312 and via circuit 111 delivers the high-level output to terminal O1 at the application time of the clock and also applies the high-level output to circuit 112 to set JK-type FF212 of the next step. Thus terminal O2 features the high level by the next clock and via FF212. On the other hand, FF211 is reset to the initial state via circuit 111 and by the reverse output passed through FF211, OR gate 311, inverter 411 and others. At the same time, JK-type FF2ij which is set by the non- inverse output of the preceding step and with no operation of the logic sum circuit generates the high-level output to terminal Oj by the 3rd clock. Thus the optional bit number and output area can be designated through a simple constitution.
