Abstract: PROBLEM TO BE SOLVED: To provide a full-color flat display device which is suitable as a high- definition large screen display for interior use and which is low cost, high luminance and long life. SOLUTION: Green and blue light sources G, B are prepared from organic EL elements using a light emitting layer emitting green light and a light-emitting layer emitting blue light, respectively, on an assembling substrate 1 for an EL device having through holes 1a in the position of a red light source. Red light sources R prepared by molding a red lightemitting LED semiconductor pellet in a transparent resin and mounted on a LED assembling substrate 2 are inserted into the through hole 1a. The height of the light-exiting face of the light source R from the substrate face of the organic EL assembling substrate 1 is made almost equal to the height of the light exiting face of the light sources G, B.  The height of each LED semiconductor pellet from the substrate face of the organic EL assembling substrate 1 is determined in such a manner that the viewing angle of each color light of green, blue and red is almost equal to others.

Title: Line thermal head
Inventor: SASABE SETSUO
IPC: B41J2/485
Filed: 1990-10-19
Abstract: PURPOSE:To print a turned letter without forming and storing a turned letter pattern by providing a shift register capable of printing data from both of the left and the right and controlling the input direction of character data to the register by a shift signal. CONSTITUTION:A shift register 1 successively shifts printing data from the right or the left to input the same. In order to set an input direction to the right or the left, a direction command signal is sent to a register direction command terminal (d) and, when this signal is a high level, the data is inputted from the right at each time when a clock signal is inputted to be stored as normal letter pattern data. When the d-terminal signal is a low level, the data is inputted from the left to be stored as turned letter pattern data. The character data is shifted to the right or the left by the clock signal. A driver gate 3 controls the supply of a current to a heater 4 on the basis of a strobe signal according to the character data stored in a latch register 2 and heat is generated from the heater on the basis of the character data to print the character data on recording paper.

Title: Transmission method for densely coupled signal
Inventor: WATARI TATSU
IPC: H04B5/00
Filed: 1988-11-10
Abstract: PURPOSE:To attain immunity against external noise and to prevent reception electric field intensity from being changed due to the movement of an electric equipment by arranging a signal cable with two insulation conductors twisted in pairs and coupling the antenna with the signal in the TEM mode formed when a signal is propagated between the insulation conductors. CONSTITUTION:A couple of loop antennas 32, 32' are provided on an opposite position to a pair twisted cable 11 at a prescribed interval via a supporting member 31. When parallel conductors are twisted at a prescribed pitch, an electromagnetic field is changed in a sinusoidal shape in the axial direction with respect to the direction of the parallel conductors perpendicular to the aperture, that is, the direction of the loop antenna 32. Then the electromagnetic field at a sufficiently remote location from the twist pitch P is cancelled by the electromagnetic fields of opposite phase to each other from line segments by P/2 and the electromagnetic field strength is rapidly attenuated. Thus, the noise coming from a remote location is cancelled by all the line segments of the pair twisted cable, thereby forming a transmission system with a high noise elimination capability. Moreover, the stable transmission system is formed by twisting the parallel conductors 14, 14' without capacitance unbalance with the earth system.

Filed: 1985-12-18
Abstract: PURPOSE:To omit a latch circuit and to simplify the overall constitution of a device by using a discriminator which secures a detecting/holding function for full waveheight in an amplifier and discriminates the output with the prescribed reference voltage. CONSTITUTION:An electrostatic capacity type keyboard consists of a control means 20, a drive circuit 22, a variable capacity switch matrix 24, a selector 26, etc., and recognizes the operating state of the switch selected by the means 20.
