Abstract: The present invention is to provide an economical and efficient method of reducing drying shrinkage of a cement-based hardened body without requiring the cost and/or the labor and time. A cement-based hardened body is impregnated with a solution containing urea or a solution containing sulfate together with urea. An impregnation treatment may be by a method of coating or spraying the cement-based hardened body with the solution, or alternatively, immersing the cement-based hardened body in the solution containing both urea and sulfate for a predetermined period of time. The solution containing both urea and sulfate may be a solution prepared simply by dissolving both urea and sulfate in water. Besides, there are no particular limitations on a liquid allowing dissolution of both urea and sulfate, so long as it causes no impairment of a drying shrinkage reduction effect, and therefore, a solution having the drying shrinkage reduction effect in itself is also applicable for use of a solution containing both urea and sulfate in a state of being dissolved in such solution.

Abstract: A control device for an electric compressor, capable of successfully controlling a drive motor of the compressor in response to the load fluctuation having complicated frequency components even when the motor is controlled in a sensorless manner, is provided. The control device for an electric compressor includes: a repetitive control portion 5 to which a rotation speed difference between a target rotation speed of a motor which drives the compressor and the estimated rotation speed is input to perform a repetitive operation using the rotation speed difference of one preceding cycle of the compressor, thereby reducing the rotation speed difference; a pressure detecting portion 1 for the compressor; and a reset signal generation portion 4 calculating a timing of one rotation of the compressor by counting the number of predetermined parts of load fluctuations of the compressor based on the pressure value of the compressor, thereby outputting a reset signal to the repetitive control portion according to the timing.

Abstract: Provided is a three-dimensional retina image generator that can detect, in a precise manner, the scanning position displacement during scanning of the retina with a simple configuration and, as a result, and can obtain a high-quality retinal image with a reduced influence of speckle noise therein. In order to detect the movement of retina R, the three-dimensional retina image generator has: second light source unit 210 that outputs a line beam to be imaged on retina R; positional displacement detector 220 that detects the line beam reflected from retina R and that detects the “displacement” of the scanning position during scanning of retina R; and dichroic mirror 230 that causes the line beam to propagate along the same light path as that of the object light scanning beam in inspection unit 140.

Abstract: A mesa-shaped superconducting-superlattice structure is formed and adhered with epoxy onto a dielectric substrate where plural superconducting layers and plural insulating layers are naturally and alternately stacked. A null/4 micro strip line (which means the length of the strip line is one-fourth of the wavelength of a microwave to be introduced) is electrically connected via a metallic film onto the mesa structural portion of the superconducting-superlattice structure, and a metallic electrode is electrically connected to the additional mesa structural portion of the superconducting-superlattice structure via a metallic film.
