    摘要： An electrical dimmer device and its driving method applicable to, for example, an image pickup unit and a display unit operate so that when a control signal for stop adjustment is changed from its current value of stop adjustment to a larger value, which occurs when the light transmissivity of a positive type liquid crystal is raised, or when the light transmissivity of a negative type liquid crystal is lowered, the control signal is temporarily varied to an intermediate value that is larger than the larger value. The energy of the varied larger value and a time during which that varied value is applied are determined in accordance with predetermined values. By doing so, it is possible to make a response speed when changing the light transmissivity extremely faster and thus attain a response time, of for example, one field period of time or less required for a stop mechanism of a video camera.

    摘要： Disclosed is an image-blur compensating device including an optical axis changing unit changing an optical axis, an actuator driving the optical axis changing unit, a displacement detector detecting a position of the optical axis changed by the optical axis changing unit, an angular velocity detector detecting an angular velocity applied from outside, and a target displacement calculator calculating a driving amount when the actuator has driven the optical axis changing unit based on the angular velocity detected by the angular velocity detector and the position detected by the displacement detector. The target displacement calculator then obtains, as a result of compensating an amount of influence on the position of the optical axis, a driving amount when driving the actuator based on the calculated driving amount. The image-blur compensating device further includes a driver driving the actuator based on the driving amount calculated by the target displacement calculator.

    摘要： A control device for cylinder reducing operation of a multi-cylinder engine for a vehicle controls the number of working cylinders in the engine more appropriately for fuel economy while ensuring the operational stability of the engine and comfortable drivability of the vehicle. The control device comprises a detector detecting engine output torque and judges if cylinder reducing operation is to be executed while referring to the engine output torque. Because of the detection of engine output torque, cylinder reducing operation will be executed as long as torque requested of the engine is available from the reduced number of working cylinders, thereby ensuring the generation of torque required in operating the engine while saving fuel as much as possible. Through a learning process, criteria for the judgment of execution of cylinder reducing operation are modified to be adapted for any variation of engine output performances.

    摘要： A lens position detecting device 200 has a position detecting magnet 202, a magnetic force detecting sensor 204, a positional information generating means 206, etc. The position detecting magnet 202 is mounted on a rear surface of a lens holder frame 1460. The magnetic force detecting sensor 204 serves to generate a detected signal having a magnitude depending on the intensity of a magnetic force generated from the magnetic poles of the position detecting magnet 202. The magnetic force detecting sensor 204 is disposed on a straight line that passes through the position detecting magnet 202 parallel to the optical axis. The magnetic force detecting sensor 204 outputs a detected signal having a voltage corresponding (proportional) to the intensity of the magnetic force. An amplifying circuit 208 of a positional information generating means 206 amplifies the detected signal Ss from the magnetic force detecting sensor 204.
