  • Publication number: 20020003648
    Abstract: The optical transmitter comprises a light source which inputs continuous optical signal and a driving circuit which inputs driving signal to an optical modulator of Mach-Zehnder type. A photo coupler separates a part of the output of the optical modulator. A photo diode converts this part into electric signal. A band-pass filter and a pre-amplifier extract a frequency component of the driving signal contained in the electric signal. A mixer conducts synchronous detection between the driving signal and the extracted frequency component. Finally, a bias voltage control circuit controls a bias voltage based on a result of the phase comparison.

  • Patent number: 6008497
    Abstract: A laser apparatus comprises storage means for storing a power source voltage of each pulse at the time of continuous pulse oscillation for one cycle, with each voltage correlated with an identifier which specifies the respective pulse, and output control means for, when a pulse is generated, reading from the storage means the source voltage of a pulse having the same identifier, and performing pulse oscillation on the basis of the source voltage. Thus the influence of the spiking phenomenon during a burst mode operation is eliminated as much as possible, and thereby the accuracy of laser beam machining is still more improved.

  • Patent number: 6009371
    Abstract: Vehicle-installed internal combustion engine control apparatus and method maintain a good operating condition of the internal combustion engine even if the opportunity of control learning is limited. To adjust the closed-state opening of a throttle valve, that is, opening of the throttle valve under a non-load condition, feedback control of the opening of the throttle valve is performed so that the idle speed approaches a target revolution speed, while the non-load idling of the engine is being performed. A feedback correction amount for the feedback control is stored as a learned value. The learned correction value is reflected in the next and later operations of the closed-state opening control of the throttle valve, so that a proper closed-state opening of the throttle valve is set. During the learning of the feedback correction amount, the engine is inhibited from being stopped.

  • Patent number: 5991683
    Abstract: The present invention prevents a decrease in efficiency due to energy circulation in a power transmission path in a power output apparatus having an engine and a motor as power source. In the power output apparatus, a planetary gear 120 has a sun gear shaft linked with a generator MG1, a ring gear shaft linked with a motor MG2, and a planetary carrier linked with an output shaft of an engine 150. The power output apparatus carries out a control procedure to avoid energy circulation, which goes through the planetary gear 120, the motor MG2, and generator MG1, and the planetary gear 120, and thereby prevent a decrease in efficiency. The energy circulation occurs when the motor MG2 converts the power output from the engine 150 to electric power and the generator MG1 carries out power operation with the regenerated electric power.
