摘要： In at least one embodiment of the disclosure, a light control device includes a light blocking module to block a luminous flux passing through the light control device in a direction parallel to a system optical axis. The light blocking module includes a first and a second light blocking member. The first light blocking member includes a cutout portion at an end near a system optical axis, the first light blocking member configured so as to change a size of an area blocking the luminous flux in accordance with an opening and closing operation of the light blocking module. The second light blocking member is disposed in proximity to the first light blocking member and configured so as to increasingly block the luminous flux from passing through the cutout portion of the first light blocking member in accordance with the closing operation of the light blocking module.

摘要： In at least one embodiment of the disclosure, a projector includes a light shield unit that shields a portion of a light emitted from a light source. The light shield unit is driven by a drive mechanism and rotates around a predetermined rotation axis to change a size of a light shield area. The light shield unit includes a leading edge having a contour defined by a plurality of first edges and a second edge disposed between the first edges. The second edge configured so as to be shifted toward the light source and away from the first edges during rotation of the light shield unit.

摘要： When a current that flows into a power output element is greater than a predetermined value, pulse width-modulated signals are formed which vary in inverse proportion to the current value in order to drive the power output element. When an excess current flows into the power output element, therefore, the power output element is allowed to intermittently operate for only short periods of time, and the current can be decreased during the current-limiting operation.

摘要： An information processing apparatus employs a liquid crystal display and a fluorescent lamp for backlighting the screen of the liquid crystal display. A lighting circuit for supplying alternating current lighting power to the fluorescent lamp receives input power from either a commercial alternating current power source or from a direct current battery. The level of the lighting power supplied to the fluorescent lamp is determined based upon a determination of whether the input power is being supplied from the commercial power source or from the battery.

摘要： A semiconductor integrated circuit device is supplied with internal circuit operating voltage and/or internal circuit ground potential from the outside through a unidirectional element, and the device is provided with a unidirectional element disposed so as to pass current flowing from a circuit internal ground potential point toward an input and/or output terminal and/or a unidirectional element disposed so as to pass a current flowing from the input and/or output terminal toward an internal circuit operating voltage point. According to the above, signals supplied to the input and/or output terminal can be enlarged without being restricted by the level of the internal circuit operating voltage and/or the internal circuit ground potential by virtue of the switching function of the unidirectional elements.
