摘要:
Conventional drivers for transducers oftentimes did not provide an efficient driving mechanism because the driving signal was not “close enough” to the natural frequency of the transducer. Here, a driver for a transducer is provided that measures the natural frequency of the transducer and generates a driving signal accordingly. Thus, a more efficient driver is provided.

An processing apparatus comprises a laser oscillator, an overall control device which controls an operation of the laser oscillator, and a plurality of processing units. The processing unit comprises a holding part which movably holds a processed object, an optical system which guides the laser beam, oscillated from the laser oscillator, toward the processed object, a shutter which selectively prevents the laser beam from reaching the processed object, and an individual control device which controls an operation of the holding part, and transmits a laser request signal to the overall control device. When at least one of the plurality of individual control devices transmits the request signal, the overall control device controls the shutter of the processing unit, which has transmitted the laser request signal, to enable the laser beam to reach the processed object, and drives the laser oscillator to allow the laser oscillator to oscillate the laser beam.

An exhaust purification apparatus for an internal combustion engine includes a catalyst unit disposed in an exhaust passage of the engine, upstream and downstream air-fuel-ratio sensors disposed upstream and downstream, respectively, of the catalyst unit, a main-feedback controller, and a sub-feedback controller. The main-feedback controller calculates a main-feedback control quantity on the basis of an output value of the upstream air-fuel-ratio sensor and a predetermined upstream-side target value, and corrects, on the basis of the main-feedback control quantity, the quantity of fuel injected by an fuel injector. The sub-feedback controller calculates a sub-feedback control quantity on the basis of an output value of the downstream air-fuel-ratio sensor and a predetermined downstream-side target value, and corrects, on the basis of the sub-feedback control quantity, the quantity of fuel injected by the fuel injector, independently of the correction of the fuel injection quantity by the main-feedback control means.
