    摘要: In a method of manufacturing a semiconductor optical waveguide array in an ultra-high integration, the device yield per wafer is considerably increased and uniform and improved characteristics are obtained. In this method, there is manufactured a semiconductor optical waveguide array including a plurality of optical waveguides in an array structure in stripe-shaped growth regions enclosed by dielectric thin films on a substrate. The waveguides are fabricated through a selective crystal growth process and include a semiconductor multilayer structure including a quantum well layer or a semiconductor multilayer structure including a bulk layer. Namely, there is formed a plurality of stripe-shaped growth regions elongated parallel to each other, the regions being enclosed with a dielectric thin film. In each growth region, a semiconductor multilayer structure is selectively grown by metallo-organic vapor phase epitaxy (MOVPE). In the selective growth, the growth regions are parallel to each other with an interval therebetween, the interval being less than a diffusion length of a source material in a reactive tube during the crystal growth. Assuming that the dielectric thin film arranged between the respective growth regions has a width Wa and a first outer-most dielectric thin film and a second outer-most dielectric thin film arranged respectively outside of outer-most ones of the growth regions respectively have widths Wm1 and Wm2, there is satisfied a relationship of Wm1>Wa and Wm2>Wa.

    摘要: An electric device has an electric power measurement unit with an electric power detection element measuring consumed electric power and an information communication element transmitting the measured power. An electric power meter has an information communication element measuring and transmitting total electric power consumed indoors. An information processing unit stores the measured values in every predetermined sampling period. If a difference α of two measurement values of the electric power detection element is a finite value, the information processing unit calculates and stores both a difference β of two measurement values of the electric power meter corresponding to the two measurement values and β/α, and calibrates the amount of electric power consumed by the electric device and that is measured by the electric power detection element using a median of values of β/α obtained in a predetermined measurement period or a median of a predetermined number of values of β/α.

    摘要: A secondary battery has a progressively deteriorating SOC in which battery performance deteriorates when the secondary battery is stored, and is charged and discharged by a control device. An information processing device stores a preset first threshold smaller than the progressively deteriorating SOC of the secondary battery and a preset second threshold greater than the progressively deteriorating SOC, and separates the range from the minimum SOC to the maximum SOC of the secondary battery into, at least, two regions by setting the section from the first threshold to the second threshold as a boundary to thereby cause the control device to charge or discharge the secondary battery within any of the above regions.
