Abstract: PURPOSE:To attain the synthetic display of two-format color information consisting of dot data and a color code by converting color code information into the density data of three primary colors, converting the three-primary color dot information into density data having the same format as the density data of three primary colors and switchably displaying both the density data. CONSTITUTION:Since respective color data in the three-primary color dot information are binary data and the respective color data of the three-primary color density data are many-valued data, the formats of both the data are different. In order to unify the output format, the dot data are two-dimensionally developed to an nXn matrix kand the dot density is calculated by the nXn matrix size to obtain the many-valued output of the three primary colors. In the case of the color code, a color code dictionary (lookup table LUT) 12 is loaded from a work station to a color code memory 8 and a three-primary color many- valued output corresponding to the color code is obtained from the memory 8. Consequently, the image data of two formats unified to a single output format can be synthetically displayed on the same color display device 15.

Title: Current-feedback-bias-type transistor amplifier circuit
Inventor: MOGI SATOSHI
IPC: H03F1/34
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To make constant a base-emitter voltage irrespective of the level of a high frequency signal and to prevent the breakdown of a transistor owing to the secular change by controlling the base bleeder voltage of the transistor according to the level of the high frequency signal. SOLUTION: The control voltage 9 of the output of a differential amplifying part 7 is determined by -(resistance 16/resistance 17)×(detection voltage 18 - reference voltage 8). An AGC amplifier is connected to the front stage of a circuit to obtain the relation between a coupling signal 5 and the control voltage 9 with defining that the reference voltage 8 is 2V. The high frequency signal 2 supplied to the base of the transistor 4 is amplified in A-class operation and outputted from an output terminal 15, and the base-emitter voltage keeps the normal voltage. Even if the AGC amplifier is abnormal, a voltage applied to the bleeder resistance is lowered and the base-emitter voltage keeps the normal voltage, so that a reverse bias phenomenon is avoided.
