Title: Multipass distortion suppressing system
Inventor: ITO TSUTOMU
IPC: H03H21/00
Filed: 1988-12-22
Abstract: PURPOSE:To suppress multipass distortion and to attenuate a noise outside a band by extracting a multipass distortion component included in a received signal, and changing the central frequencies of a variable narrow band filter. CONSTITUTION:An envelope detector 11 detects the envelope level of the output signal of an amplifier 3a, and inputs it to an AC component detector 12. When the multipass distortion exists in an antenna input, the envelope level sharply changes. When the multipass distortion exists, the AC component detector 12 outputs the signal at the level proportional to the sharpness of the envelope level, and controls the band width of a variable narrow band filter 13. When the multipass distortion is large, the band width of the variable narrow band filter 13 is broadened. When the multipass distortion is small, the band width of the variable band filter 13 is narrowed. At such a time the noise quantity passing through the variable narrow band filter 13 decreases, and a CN ratio in the system is improved.

Title: Organic electroluminescence display device
Inventor: ONIKUBO SHUNICHI
IPC: H01L51/50
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a high-definition display device capable of emitting light with high brightness and high efficiency, little in luminescence deterioration, high in reliability, and easy in element preparation and in driving, by using an aromatic tertiary amine compound as luminescent material for each color of the display device having a plurality of coloring areas patterned with a multi-color luminescent layer. SOLUTION: The plurality of coloring areas comprise three areas, blue, green, and red or orange coloring areas. The aromatic tertiary amine compound is a compound having two to six units of tertiary amine nitrogen, preferably a diamine compound. By changing its chemical structure, fluorescent colors in the entire visible region can be obtained. In order to widely change the luminescent color, it is preferable for a nitrogen atom to be directly bonded to a condensed aromatic ring and it is more effective that all the nitrogen atoms are bonded to the same condensed aromatic ring. A matrix drive element has an electrode structure stripe-shaped in the x-axis and y-axis directions, and when an image is displayed, a row electrode (or a column electrode) is selected in order to input an electric signal, thereby addressing an arbitrary pixel to form the image.
