Abstract: To provide a controller for motor which can reduce a torque ripple up to high frequency, without amplifying unnecessary noise and vibration. A controller for motor estimates an interlinkage flux based on the applied voltage and the detection value of current; estimates an output torque based on the detection value of current and the estimation value of interlinkage flux; extracts a pulsation component from the estimation value of output torque; calculates a voltage command correction value based on the extraction value of pulsation component; calculates a voltage command after superimposing by superimposing the voltage command correction value on the voltage command basic value; and applies voltage to winding based on the voltage command after superimposing.

Abstract: A thermoelectric conversion element that has a power generation layer containing an iron-aluminum based magnetic alloy material containing equal to or more than 70 weight percent of iron and aluminum in total. The power generation layer generates an electromotive force, due to an anomalous Nernst effect that develops in the magnetic alloy material in response to a temperature gradient applied thereto, in a direction intersecting both the magnetization direction of the magnetic alloy material and the direction of the applied temperature gradient.

Abstract: A method for the cooking-free saccharification of starch using an amylase produced by Corticium rolfsii AHU 9627 or its variants. According to the method, even a high viscous suspension of 10% (w/v) or more raw-corn starch is almost completely hydrolyzed within 8 hours. The saccharification is proceeded at a higher temperature and a lower pH compared with those in known methods utilizing other amylases which are able to hydrolyze uncooked starch, so that the propagation of the infectious bacteria which would affect the saccharifying efficiency can be avoided.
