Title: Bias controller of amplifier
Inventor: FUREDERITSUKU GUURUGU
IPC: H03F1/02
Filed: 1995-02-10
Abstract: PURPOSE: To improve power efficiency and linearity by adjusting the bias of an amplifier so that an out-of-band real emission level is made equal to an out-of-band required emission level in accordance with a required output power value. CONSTITUTION: A control means 6 in the bias controller 5 receives a required output power value 7 as linearity control information from an external microcontroller and outputs a bias signal 4 corresponding to the power value 7 to an amplifier 1. The signal 4 is previously determined at the time of design so that the out-of-band real emission level is almost equal to the out-of-band required emission level in accordance with each required output power value in an available range. At the time of receiving the signal 4, the amplifier 1 adjusts the biases of respective transistors, amplifies an input signal 2 and sends an output signal 3. Consequently high power efficiency and high linearity can be obtained independently of the output power of the amplifier 1.

Title: Photoelectric converting circuit for photodetection
Inventor: SAKAMOTO SHINJI
IPC: G02F2/02
Filed: 1984-02-10
Abstract: PURPOSE:To simplify a circuit, and to realize a digital photodetecting photoelectric converting circuit which can respond enough even in case of a high speed, by providing a constant-current circuit for converting a photocurrent to a variation of a base-emitter voltage of a control outputting transistor (TR). CONSTITUTION:When there is no optical input, a photocurrent does not flow to a photodiode D1, and a TRQ2 becomes off. In this case, a TRQ1 is biased by a constant-voltage diode D2 and becomes on, and a constant-voltage output is obtained in an output Vout. This output can be Adjusted by a resistance R4. On the other hand, when there is an optical input and the TRQ2 is turned on, the Q2 makes a resistance R3 a load and makes a current flow. When a potential difference generated in the resistance R3 becomes large up to an extent that it cannot be disregarded comparing with the diode D2, the TRQ1 is turned off and the output Vout becomes ''0''V. In this way, with respect to the optical input, a phase inversion output whose waveform has been regenerated is obtained as the output Vout, and an output voltage is controlled by a base.emitter voltage, therefore, the output voltage is varied as an exponential function even in case of a variation of an input current, and an output voltage having a sufficient sharpness is obtained.

Abstract: PURPOSE:To extract black data in the form of color sequential color image data as they are by holding one value by a holding means according to the comparison result of a comparing means and repeating comparing operation by the comparing means according to the number of color component signals. CONSTITUTION:Input image data and image data outputted by a masking part 202 are inputted to a selector 203, which selects the input image data normally with a selector control signal 1 sent from a control part 200. It the color correction of an input system is not performed sufficiently, the image data outputted by the masking part 202 is selected and outputted with the control signal 1 and the serial image data outputted by the selector 203 is inputted to a black extraction part 204. Minimum values of Y, M, and C of one picture element are used as black data, so the black extraction part 204 detects the minimum values of Y, M, and C and the detected black data are inputted to a UCR part 205. Consequently, black extraction is performed in the form of the color sequential image data as they are without converting the input color sequential image data into parallel data.
