Abstract: While light of R, G and B is switched from one to another and directed to a plurality of light shutter elements made of PLZT, a voltage is applied in accordance with image data between individual electrodes for the respective light shutter elements and a common electrode for all the light shutter elements. While a half-wave voltage Vr for light of R is applied to the individual electrodes, the voltage applied to the common electrode is altered to 0V, Vr-Vg and Vr-Vb in synchronization with switch of the three primary colors so that half-wave voltages for the respective colors can be applied to the light shutter elements.

Abstract: A voltage regulator includes an input terminal at which an input voltage is applied and an output terminal at which an output voltage is provided to a load. The load defines a load current. A gate modulated diode is connected between the input terminal and the output terminal. The gate modulated diode has a forward voltage drop that is controllable by a voltage signal applied to a gate of the gate modulated diode. A first operational amplifier, capable of operating with a low supply voltage, is operable to apply the voltage signal at the gate of the gate modulated diode to control the forward voltage drop. The output voltage is regulated to a predetermined low voltage when the load current is within an operational range for the voltage regulator.

The motor driving circuit includes first and second comparators, comparing a first and second pair of Hall signals from the Hall sensors, and outputting a first and second Hall signals.

The first and second Hall signals can be amplified to match the level of the third Hall signal, or vice versa.

Abstract: In a solid-state image-sensing device, when image sensing is performed, in each pixel, MOS transistors T1 and T5 are turned on and a MOS transistor T6 is turned off so that a MOS transistor T2 operates in a subthreshold region. When resetting is preformed, in each pixel, the MOS transistors T1 and T5 are turned off and the MOS transistor T6 is turned on so that the gate voltage of the MOS transistor T2 is kept constant. In this state, the MOS transistor T2 is brought first into a conducting state and then, by turning a signal ?VPS to a high level, into a cut-off state. This permits a signal proportional to the threshold value of the MOS transistor T2 to be output as compensation data.
