摘要： A current controlled signal processor adjusts the characteristics of an output frequency of a current controlled type oscillation circuit in accordance with stored information. A control current is generated dependent on the stored information. The output frequency of a current controlled oscillator varies dependent on the control current. The stored information may be altered, thereby allowing for the altering of the output frequency of the current controlled oscillator without requiring replacement or addition of electronic elements. Also, the present invention makes it possible to assemble the current controlled signal processor circuits into one integrated chip.

摘要： The actuator has a displacement detector and is driven intermittently through a given displacement. A mean amount of drive signals per one intermittent drive such as a mean duration of drive signals and a mean number of drive pulse signals is calculated through a predetermined number of intermittent drives. The mean amount of drive signals is intermittently applied to the actuator for a given number of intermittent drives without the displacement detection. After the given number of intermittent drives by the calculated mean amount, another intermittent drive with the displacement detection is carried out. At this time, the total duration of the drive pulse signals or number of the drive pulse signals outputted until the completion of the given displacement is compared with the calculated mean amount. If the difference therebetween is greater than a given value, the number of intermittent drives by the mean amount is reduced, or if the difference is much greater, the predetermined number of intermittent drives are carried out once again to calculate an updated mean amount. On the other hand, the difference is smaller than the given value, the number of intermittent drives by the mean amount is increased.
