20080283740 | MASS SPECTROMETRY SYSTEM AND MASS SPECTROMETRY METHOD - When a liquid mixture of two samples such as biological samples labeled with stable isotopes is subjected to a relative quantitative analysis using a liquid chromatography-tandem mass spectrometry system, various constituents are simultaneously ionized. Accordingly, sufficient time required for second mass spectrometry is not ensured, whereby some ions remain unanalyzed after measurement. To address this problem, after second mass spectrometry, amino acid sequencing is performed using the analysis data of the second mass spectrometry, which enables determination on the presence/absence of a specific amino acid labeled with a stable isotope. When the specific amino acid is present, the m/z value of an isotopically-labeled-paired ion in an MS spectrum is calculated, and non-target information for use in second mass spectrometry is created using the calculated m/z information.

A magnetic field is generated by the short-circuit current. | 09-25-2014 |
20140283374 | PERMANENT MAGNET ELECTRIC MOTOR - According to one embodiment, a rotor is configured by a rotor core and magnetic poles. Two or more types of permanent magnets are used such that each product of coercivity and thickness in the magnetization direction becomes different. A stator is located outside the rotor with air gap therebetween and configured by an armature core winding. At least one permanent magnet is magnetized by a magnetic field by a current of the armature winding to change a magnetic flux content thereof irreversibly.

20160049835 | SYNCHRONOUS RELUCTANCE MOTOR AND ROTOR FOR SYNCHRONOUS RELUCTANCE MOTOR - A synchronous reluctance motor includes: a rotor shaft; a rotor core fixed to the rotor shaft and on which a plurality of flux barriers are formed; a stator core on which a plurality of protruding stator teeth are formed; and multiphase armature windings of a plurality of poles wound around the plurality of stator teeth. The flux barriers include a plurality of first flux barriers formed to be spaced out in the circumferential direction from each other and extend in a radial direction, and a plurality of second flux barriers formed in each of circumferential angular regions sandwiched between the first flux barriers to form a curved surface convex toward the center of the rotation-axis and to spread and be spaced out in the circumferential direction from each other. | 02-18-2016 |
