Filed: 1983-12-23
Abstract: PURPOSE:To realize a broad band and a low distortion factor at large amplification by applying a prescribed current to a collector of a transistor (TR) of the 1st stage of the inverted Darlington circuit comprising two TRs. CONSTITUTION:A base of a TR7 is connected to a signal source 3, a collector and a base of the TR1 are connected respectively to a constant current source 11, an emitter of the TR7 and the collector of the TR1 are connected and grounded via a resistor 4. The emitter of the TR1 is connected to a power supply 6 via a resistor 5, the power supply 6 is connected to a current source 11 and an output signal is extracted from the collector of the TR1. Since the collector current of the TR7 is the constant current in this way, the emitter current of the TR7 is unchanged, then the change in the equivalent emitter resistance (hib) due to the emitter current change of the TR7 is not caused, the distortion due to the change in the (hib) is not produced so as to amplify a signal with a low distortion factor, thereby realizing the broad band and low distortion factor at large amplification.

IPC: G06T15/00
Filed: 1988-09-29
Abstract: PURPOSE:To attain the clipping of a three-dimensional object by suppressing a frame buffer updating by a shading means in accordance with the compared result of the Y coordinates of a point on a clipping surface corresponding to the X coordinates of a painted-out object point and the Y coordinates of the painted-out object point. CONSTITUTION:By obtaining the arbitrary clipping surface perpendicular to an X-Y plane as the equation of the straight line on an X-Y plane, Y coordinates of the point on the clipping surface corresponding to the X coordinates of the painted-out object point are obtained by the operation of a simple expression (Y=aX+b) from the X coordinates. By comparing the Y coordinates obtained by the operation with the Y coordinates of the painted- out object point by a comparing means 16, it can be discriminated whether or not the corresponding point is the point which is the object of the clipping. Then, in accordance with the compared result of the comparing means 16, the frame buffer updating due to a shading means 13 is suppressed. Thus, the clipping of the three-dimensional object due to the clipping surface only perpendicular to the X-Y plane can be performed.

Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To make the distribution of the light quantity of an optical image formed on a photodetector means uniform without reducing the light quantity of the optical image with simple constitution. SOLUTION: Light beams radiated from plural LEDs 12 are reflected on a reflection optical member 15 and guided to a read object (source document surface 10a).
