摘要:
There is provided a communication terminal out of range determination method, a wireless communication system switching method and a communication terminal, capable of determining accurately whether or not a communication terminal is out of range. Determining whether or not the communication terminal is out of range is based on a transmission level of a transmission signal from the communication terminal to a base station.

The present invention provides a ballast water treatment system including a reaction tank in which raw water and ozone are imported and made to react each other for a predetermined period of time to kill microorganisms existing in raw water, an ozone decomposer in which water containing residual ozone discharged from the reaction tank is imported and the residual ozone is decomposed, and a circulation pump installed between the reaction tank and ozone decomposer, forming a circulation system which removes the residual ozone by means of circulating the water containing the residual ozone between the reaction tank and ozone decomposer. Accordingly, this system dispenses with a deaeration tank which would require a wide space for installation, small cost and is able to be applied to existing ships easily.

The present invention aims at providing a dispersion stabilizer for suspension polymerization of a vinyl-based compound, which gives vinyl chloride-based polymer particles having a sharp particle size distribution and a high bulk density owing to excellent dispersion stability during polymerization, and which can produce vinyl chloride-based polymer particles with few wet foams, hardly accompanied with formation of polymer scales and foamy polymers attributable to dry foams, with less coloring, and having excellent heat resistance. The dispersion stabilizer of the invention comprises a PVA-based resin having a 1,2-diol component at a side chain and a degree of saponification of 65 to 87% by mol.

According to one embodiment, a calibration section controls an LD driving section so as to carry out test writing on a recording layer of an optical disc using a light pulse having relaxation oscillation, irradiates the test-written area with a reproduction laser beam so as to detect reflected light, and determine write strategy based on the detected result. A recording process is executed on the optical disc by using the light pulse having relaxation oscillation based on the write strategy determined by the calibration section.

The absolute angle calculation apparatus includes a calculation circuit calculating an absolute angular position based on a spatially modulated component in a photoelectrically-converted signal string. The calculation circuit includes a photoelectrically-converted signal string storage storing previous and current photoelectrically-converted signal strings obtained, for interpolating the absolute angular position, within a set time shorter than an absolute angle calculation time required to calculate the absolute angular position; a correlation detection circuit detecting a correlation between the previous and current photoelectrically-converted signal strings in the photoelectrically-converted signal string storage and detecting a shift amount therebetween; and an interpolation calculation circuit interpolating an inter-pattern absolute angular position equivalent value based on the shift amount obtained by the current measurement. The calculation circuit calculates an interpolated angle based on the shift amount and the absolute angular position equivalent value, adds the calculated interpolated angle obtained at the current measurement to the absolute angular position obtained at the previous measurement to calculate a current absolute angular position.
