Abstract: A thermal displacement correction device for a machine tool is provided with detection result determination unit configured to determine, based on an actual position and a reference position detected by position detection unit, whether or not the actual position is based on correct detection, correction error calculation unit configured to calculate a correction error in the actual position if it is determined that the result of detection is based on correct detection, and correction amount modification unit configured to modify a thermal displacement correction amount based on the correction error.

Abstract: A machine controller intercommunicates with, and issues machining program commands to, a plurality of peripherals. The controller receives work status information on the peripherals, calculates the total power consumption by the plurality of peripherals based on the received information, and decides the work start timing for the peripherals such that the total does not reach a preset upper limit.

Abstract: A concentration measurement apparatus measures a temporal relative change amount (?cHb, ?O2Hb) of either or both of total hemoglobin concentration and oxygenated hemoglobin concentration in the head that vary due to repetition of chest compression, and includes a light incidence section making measurement light incident on the head, a light detection section detecting the measurement light propagated through the interior of the head and generating a detection signal in accordance with the intensity of the measurement light, and a CPU determining, based on the detection signal, the relative change amount (?cHb, ?O2Hb) and performing a filtering process of removing frequency components less than a predetermined frequency from frequency components contained in the relative change amount (?cHb, ?O2Hb).

Abstract: A process for producing a sucrose fatty acid ester wherein the sucrose fatty acid ester is recovered from a reaction mixture prepared by reacting sucrose with a fatty acid alkyl ester in the presence of an alkali catalyst by using dimethyl sulfoxide as a reaction solvent, the process comprising: (i) subjecting the reaction mixture to a first liquid-liquid extraction by using a hardly water-miscible organic solvent, which is selected from an alcohol having at least 4 carbon atoms and a ketone having at least 4 carbon atoms, and water as extractants, with regulating the pH value of an aqueous phase to 3 to 7.
