Title: Display device
Inventor: OOKUBO YUKITOSHI
IPC: G02F1/135
Filed: 1980-04-02
Abstract: PURPOSE: To obtain a superior display function causing no parallax by forming a thin film transistor (TFT) array on one substrate of a display device and arranging optical filters on the electrodes of the array so that the adjacent filters have different spectral characteristics and superposed on each other at edges.  
     CONSTITUTION: Gate electrodes 1", 1'''..., semiconductors 2", 2'''..., source wires 3, 3'... and drain electrodes 4", 4'''... are set on glass substrate S to form a TFT array, and optical filters 20, 21, 22 are formed on the electrodes so that the adjacent filters have different optical characteristics and are superposed on each other at edges. Filters of blue 20, green 21 and red 22 are used by an additive color process, or three color elements of cyan 20, magenta 21 and yellow 22 are combined as one unit to give a color display picture element. Chemically stable org. pigments are added to the filters to provide insulation, thus preventing the electrolysis of a liq. crystal and the short circuit of an opposite electrode. The filter double as a light shielding material for the gate and source wires. By making the height of the superposed parts of filters 20W22 equal to the space between substrates S, 7, the parts may be utilized as spacers to uniformize the thickness of a liq. crystal layer.

Title: Optical semiconductor device
Inventor: NOBUHARA HIROYUKI
IPC: H01L27/15
Filed: 1985-03-08
Abstract: PURPOSE:To take out a large current from a photodiode part, by a structure, in which a part of the photodiode part is inclined to the direction, into which a monitor beam from a laser diode part is inputted. CONSTITUTION:In a photodiode part PD, a P-type AlGaAs clad layer 5 is exposed by removing P<+> type GaAs electrode contact layer 6 selectively and serves the role as a so-called window layer in the photodiode. A monitor beam B2 from a laser diode part LD is all inputted into a GaAs active layer 4 through the layer 5, because the energy band gap of the P-type AlGaAs clad layer 5 is larger than that of the GaAs active layer 4. In this structure, a part of the photodiode part PD is inclined to the direction of the monitor beam B2 from the laser diode part. Therefore the light receiving area is increased to a large extent, and a large amount of current can be taken out.

Title: Recognition system for graphic pattern
Inventor: TAKANO HIDEHIKO
IPC: G06T1/00
Filed: 1984-03-08
Abstract: PURPOSE:To recognize a graphic pattern easily by converting the graphic pattern of a component which has a simple geometric form into projection charts, and calculating a shape identification value from feature values of the numbers of positive and negative pulses of the differential waveforms of the projection charts. CONSTITUTION:An object of recognition has a graphic pattern which consists of a closed loop composed principally of straight lines parallel and perpendicular to some straight line and a straight line having a 45 deg. angle, and some of sides is arrayed along a guide. The graphic pattern which is supplied in an array is read by a pattern input device and converted into binary graphic data 1. Then, a shape analyzing device obtains X- and Y-axial projection charts 2x and 2y, and the numbers of positive and negative pulses of their differential waveforms 3x and 3y are regarded as feature values of the graphic pattern. A shape identification value is calculated from an arithmetic expression including those feature values and used to recognize the graphic pattern. Thus, the need for complicate pattern matching is eliminated.

Title: Continuous phase modulation signal demodulation circuit
Inventor: HIRAMATSU TATSUO
IPC: H04L27/14
Filed: 1991-03-11
Abstract: PURPOSE:To reduce the effect of noise by sampling a demodulation signal based on a sampling signal obtained through FM-demodulating a received continuous phase modulation signal, latching the result to a shift register and applying Viterbi decoding to the obtained signal. CONSTITUTION:A high frequency signal received by an antenna 10 is converted by a reception circuit 11 and demodulated by an FM demodulation circuit 12. A clock recovery circuit 13 compares the phase of information relating to a change point of the data being an FM demodulation output with the phase of a frequency division output from a frequency divider to recover a clock signal synchronously with a change point of a reception data and outputs the result with a delay by a half bit. An integration circuit 20 makes counting based on a high speed clock signal from a high speed clock generating circuit 21 and preset by a clock signal from the clock recovery circuit 13. The integration output is latched by a shift register 22 by the clock signal and shifted therein. A Viterbi decoding circuit 23 decodes the reception data based on the integration value. Thus, the effect of noise is reduced and the decoding accuracy of the reception data is improved.
