Satisfactory magnet torque is achieved while avoiding a reduction in the reluctance torque generated. The rotor core is provided with a plurality of magnet slots arranged in the circumferential direction of the rotor core and a gap formed of base holes and a projecting hole. The base holes extend from both ends in the circumferential direction of each magnet slot to the outer side of the rotor core. The projecting hole projects in the circumferential direction of the rotor core from at least one of peripheral portions, opposed to each other, of the base holes provided at both of the ends of the magnet slot, when viewed in an axial direction. The projecting hole is located closer to the magnet slot than to an outer peripheral side end of the base hole.


An assembling apparatus assembles beads different in particle size from each other. The assembling apparatus includes a substrate and a photothermal light source. The substrate is constructed to be able to hold a sample in which the beads are dispersed. The photothermal light source irradiates the substrate or the sample with laser beams to thereby produce a temperature difference in the sample.

The purpose of the present invention is to provide: a novel method for producing ^(18)F-labeled 4-boronophenylalanine (BPA) ; and a precursor of ^(18)F-labeled BPA. ^(18)F-labeled BPA can be produced by preparing a compound represented by formula (1) and using the compound. In the formula, R1 represents a bromo group, an iodo group, a fluoro group, a diazaborinane derivative, BX3- or BX3-M+ (wherein X represents a halogen atom; and M+ represents a monovalent monoatomic cation, a polyatomic cation or a complex cation).


An assembling apparatus (100) assembles beads (1,2) different in particle size from each other. The assembling apparatus (100) includes a substrate (10) and a photothermal light source (20). The substrate is constructed to be able to hold a sample (13) in which the beads (1, 2) are dispersed. The photothermal light source (20) irradiates the substrate (10) or the sample (13) with laser beams (201) to thereby produce a temperature difference in the sample (13).

An objective of invention is conveniently concentrating a metal in a metal ion-containing solution with high efficiency and to recover the metal from the metal ion-containing solution with high recovery efficiency. A method for concentrating or recovering a metal in a metal ion-containing solution in the present invention is the method comprising the following steps, a reduction and accumulation step to reduce the metal ion into a metal fine particle and also to accumulate the metal fine particle in the microorganism by allowing the microorganism and an electron donor B to act on a metal ion-containing solution W_(0) and thus to obtain a solution W_(1) that contains a microorganism having a metal fine particle accumulated therein; a concentration step to concentrate the solution W_(1) that contains the microorganism having a metal fine particle accumulated therein by a filtration membrane and thus to obtain a concentrated solution W_(2); and a return step to return the concentrated solution W_(2) to first step above and thus to circulate. Further, A device for metal concentration or recovering in the present invention comprises the following: a storage unit 2 to store the solution W_(1), a concentration unit 3 to concentrate the solution W_(1) that is transferred from the storage unit 2 by a filtration membrane, and a return unit 4 to return a concentrated solution W_(2) that is concentrated in the concentration unit 3 to the storage unit 2.

The present invention is a sensor for detecting a microorganism, which is provided with a detection unit (17) equipped with a detection electrode (11) and a polymer layer (14), wherein the polymer layer (14) is arranged on the detection electrode and is provided with a template having a three-dimensional structure complementary to a three-dimensional structure of a microorganism (13) to be detected. The sensor detects a microorganism on the basis of the captured state of the microorganism onto the template (15). The polymer layer (14) is formed by a manufacturing method including a polymerization step (St1) of polymerizing a monomer in the presence of the microorganism (13) to be detected to form a polymer layer (14) having the microorganism (13) incorporated therein on the detection electrode, and a disruption step (St2) of bringing at least a part of the microorganism (13) incorporated in the polymer layer (14) into contact with a solution containing a lytic enzyme to disrupt the microorganism.

This chapter deals with the transition-metal-catalyzed hydrothiolation and hydroselenation of alkynes and allenes and related unsaturated compounds with thiols and selenols. In these reactions, the regio- and/or stereoselectivities of the addition products can be controlled by switching the transition metal catalysts. Metal sulfides and selenides (RE-ML n, E = S, Se, M = Ni, Pd, Rh, Zr, Sm, etc.) play an important role as key catalyst species in these hydrothiolation and hydroselenation. The introduction of carbon monoxide into these hydrothiolation and hydroselenation systems leads to novel carbonylation with simultaneous addition of thio and seleno groups to unsaturated bonds. © 2013 Springer-Verlag Berlin Heidelberg.
