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).

In an outer covering sheet of an absorbent product, first, second and third adhesive layer elements each extending in a left-right direction are formed on a second covering sheet by spiral spray application. Each of these adhesive layer elements has wide width parts and narrow width parts which are continuous with the wide width parts, respectively. Therefore, hot melt adhesive can be stably discharged across the entire length of the adhesive layer element, unlike in the case where only wide width parts are formed intermittently. As a result, it is possible to obtain the outer covering sheet which is a sheet member having the adhesive layer elements with desired shapes where unevenness is decreased. In the absorbent product which is manufactured with use of the sheet member, the comfort level of the wearer can be prevented from decreasing due to unevenness of thickness of the adhesive layer elements.

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

An actuator includes a fixed section that includes a spindle and a coil fixed to the spindle, a first movable section that includes a first magnet magnetized in an inside-outside direction and disposed to cover the outer peripheral surface of one end in an axial direction of the fixed section, that is mounted on the spindle in an elastically-maintained state, and that is movable in the axial direction, and a second movable section that includes a second magnet magnetized in the inside-outside direction and disposed to cover the outer peripheral surface of the other end in the axial direction of the fixed section, that is mounted on the spindle in an elastically-maintained state, and that is movable in the axial direction. When current flows in the coil, the first movable section and the second movable section move in the opposite directions.

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.
