    摘要: In a method of fabricating a semiconductor optical device, a semiconductor region is formed by growing an InP lower film, a active region, an InP upper film and a capping film on a substrate sequentially. Material of the capping film is different from that of InP. Next, a mask is formed on the capping film, and the semiconductor region is etched using the mask to form a semiconductor stripe mesa, which includes an InP lower cladding layer, a active layer, an InP upper cladding layer and a capping layer. The active layer comprises aluminum-based III-V compound. A width of the top surface of the capping layer is greater than that of a width of the bottom surface of the capping layer. A width of the top surface of the InP upper cladding layer is smaller than that of the bottom surface of the InP upper cladding layer. The minimum width of the semiconductor mesa is in the InP upper cladding layer. After forming the semiconductor stripe mesa, thermal process of the semiconductor mesa is carried out in an atmosphere to form a mass transport semiconductor on a side of the InP upper cladding layer, and the atmosphere contains V-group material.

    摘要: The present invention provides an optical module for light-transmitting a first optical signal with a first wavelength and light-receiving a second optical signal with a second wavelength in bidirectional. The optical module of the invention includes an optical fiber, a laser diode, a photodiode, an optical filter and a holder for securing the optical filter. The laser diode emits the first optical signal, while the photodiode receives the second optical signal. The filter reflects one of the first and second optical signals and transmits the other of first and second optical signals. The holder of the present invention includes first and second lens both built in the surface of the holder. The first lens faces the laser diode and optically couples the laser diode with the optical fiber, while the second lens faces the optical fiber. Since the first and second lenses are built in the surface of the holder, the optical alignment of the laser diode and the photodiode can be automatically carried out by mounting the laser diode and the photodiode on the surface of the holder.

    摘要: A voltage-command correction unit provided between an electric-power conversion unit and a voltage-command calculation unit provides a predetermined current range including the zero level for the detected output current, and, at a first clock time when the output current enters from outside to inside of the current range, sets a zero cross timing of the output current as a clock time for switching the polarity of the correction voltage that corrects the AC voltage command calculated and output by the voltage-command calculation unit based on the first clock time and the frequency, thereby making a configuration capable of correcting the AC voltage command with the correction voltage with the same polarity as the polarity of the output current around the zero cross point of the output current.

    摘要: A CPU calculates, based on a frequency command value for driving a motor and on a state quantity of the motor, an output-voltage command value in which only the phase advances while amplitude is constant in each calculation period, without reducing the calculation period. An ASIC reflects the output-voltage command value in a triangular wave signal in a time-series order to compare with each other, and outputs a PWM signal to a switching circuit. Thus, a waveform of an output voltage is made close to a sine wave irrespective of an output frequency being high or low, and a processing load of the CPU is reduced.

    摘要: In an exercise machine, when a measurement starts, an electrocardiographic signal is detected by an electrocardiographic sensor 1 (ST33), a load drive is started (ST4), and heartbeat rate intervals of the electrocardiographic signal are sequentially obtained. A fluctuation of heartbeat rate intervals PI(n) % is obtained from a calculation formula in which the RR interval RR(n+1) of the current heartbeat is subtracted from the RR interval RR(n) of the previous heartbeat, which is then divided by RR(n) and multiplied by 100% (ST5). Entropy is calculated from 128 pieces of such PI (ST6). From the change of the entropy under the gradually increasing load (ST8), a minimum point of the entropy is obtained, which point is designated as an anaerobic threshold point (ST7). The load of the exercise machine is controlled employing this anaerobic threshold.
