    • It is intended to provide a method capable of simply aggregating magnetic particles having a surface modified with a thermoresponsive polymer at a given temperature without heating or cooling an aqueous solution containing the magnetic particles, and a separation method and a detection method of a substance to be detected in a sample using the method. The method of separating a substance to be detected from a sample includes the steps of: mixing an adsorbent and the sample in an aqueous solution to adsorb the substance to be detected on the adsorbent, aggregating the adsorbent by changing a salt concentration in the aqueous solution; and collecting the adsorbent from the aqueous solution by a magnetic force, wherein said adsorbent comprises a magnetic particle of an average particle size of 50 to 1000 nm, a surface of which is modified with a thermoresponsive polymer and is immobilized with a substance having an affinity for the substance to be detected.

    • Disclosed is an actuator that generates the reciprocating rotational motion of an electric toothbrush or similar without employing a drive transmission mechanism as a separate entity from a drive source. An actuator (100) includes a fixed body (110) comprising an outer yoke (140) having inner wall planes that respectively oppose the magnetic pole planes of unlike poles of a magnet (150) with a predetermined gap therebetween. A coil (122) is arranged to encircle the magnet (150) between the magnetic pole planes of the unlike poles of the magnet (150) and the inner wall planes of the outer yoke (140) that respectively oppose the magnetic pole planes of the unlike poles, and this coil (122) is movably supported as a movable body (120) by way of an elastic member (130) fastened to the fixed body (110). The reciprocating rotational motion of the movable body (120) is afforded by the supply of an alternating current of a frequency approximately equivalent to the resonant frequency of the movable body (120) from an alternating current supply (180) to the coil (122).

    • An actuator allows miniaturization by realizing back-and-forth rotating motion of, for example, an electric brush without a drive transmitting mechanism which is a separate entity from a drive source. In a movable body (110) of this actuator (100), an outer yoke (150) is provided with sidewalls (152 and 153) located opposing each other spaced a predetermined interval apart. A magnet (160) is provided in the outer yoke (150) through anon-magnetic body (170) and has different magnetic poles located opposing to the opposing inner wall planes of the outer yoke (150) through the air gaps. The movable body (110) is provided with a shaft (180). The fixed body (120) has a coil (128) which is located in the air gaps and which circles the magnet (160). The fixed body (120) movably supports the movable body (110) through elastic bodies (130). An alternating current supplying section (140) supplies to the coil (128) the alternating current of a frequency virtually equal to the resonance frequency of the movable body (110).

    • In a pants-type absorbent product, a first middle elastic member (47) is located along a horizontal direction in a middle front part (4022) between a pair of leg openings in an outer covering sheet (4). The first middle elastic member (47) contracts a first sheet (41) and a second sheet (42), and middle gathers are formed. Thus, it is possible to improve fitting of a middle part (402) to a wearer. In the middle front part (4022), both ends of the first middle elastic member (47) are apart from edges (121) of the pair of leg openings, and a pair of non-contracted parts (49) are provided between the both ends of the first middle elastic member (47) and the edges (121) of the pair of leg openings, to thereby improve flexibility of portions in the vicinities of the leg openings in the outer covering sheet (4).
