    摘要: A shift register of a CCD line image sensor is divided into two from the center thereof so as to transfer the signal electrical charge for output portions placed on both ends of the sensor, so that the line image sensor has a higher data rate, and reduced optical smearing. Furthermore, when a color line image sensor has been made using such line image sensors, the clearance of the sensor may be made smaller, and the amount of the correction smear for positioning alignment may be reduced.

    摘要: A C-V(capacitance-to-voltage) conversion apparatus usable e.g. for detecting physical parameters such as pressure, distance and angle. The apparatus comprises a capacitive sensor, a C-PW(capacitance-to-pulse width) conversion circuit, and a PW-V(pulse width-to-voltage) conversion circuit. The capacitive sensor converts a physical parameter to a capacitance, but has a non-linear conversion characteristic. The C-PW conversion circuit converts the capacitance to a pulse signal whose mean value is proportional to the capacitance, by controlling a charging-discharging cycle of the capacitive sensor and a reference capacitor. The PW-V conversion circuit converts the pulse signal to a d.c. voltage and at the same time compensates for the non-linearity of the capacitive sensor's conversion characteristic so that the d.c. voltage is proportional to the physical parameter.
