Provided are a method for producing a purifiedgenus plant extract having improved flavor by increasing the &#x3b1;-glucosidase inhibitory activity of the extract without significantly reducing the recovery rate of the extract concomitantly with purification; and a purifiedgenus plant extract. The method for producing a purifiedgenus plant extract includes an extraction step of bringing agenus plant-containing raw material extract including at least one of agenus plant, agenus plant extract, and agenus plant ground product, into contact with 0.1 to 20 mass % of activated carbon in the presence of an extraction solvent.

A charging system for communicating with an RFID tag on a vehicle traveling with the RFID tag attached thereto, and thereby performing charging processing in relation to the vehicle. The charging system is provided with: an RFID information acquisition unit for acquiring RFID information written onto an RFID tag detected by a roadside communication device for communicating with the RFID tag; an external appearance information acquisition unit for acquiring external appearance information relating to the RFID tag or a vehicle body of the vehicle; a point computation unit for determining the respective invalidity of each of a plurality of pieces of determination information, including external appearance determination information in which the RFID information and the external appearance information are combined, and calculating points on the basis of the invalidity; and a determining unit for determining whether or not the vehicle is a fraudulent vehicle on the basis of the points.

Charging system, charging method, and program

An optical head enabling a size reduction so that the optical head can be stored in an opening of a cartridge for a disk and enabling an improvement in the dynamic performance as the density and transfer rate are increased is provided. In a two-axis actuator optical head capable of driving an objective lens () along the Z axis in the focus direction, that is, vertical to the surface of the optical disk and along the X axis in the tracking direction, that is, the radial direction of the optical disk. The objective lens () is disposed in the center of the coil bobbin (), a focusing coil () is disposed around the coil bobbin () and is wound around the X axis, and tracking coils (and) are disposed on both ends of the coil bobbin () in the X axis direction and are wound around the X axis. Pairs of magnets (to) are disposed plane-symmetrically with the Z-Y plane including the Z axis aligned with the optical axis of the objective lens () and the Y axis and with the Z-X plane including the Z axis and the X axis.

Optical head

An optical head, able to reduce thermal stress generated in an optical lens mounted on a bobbin, having a bobbin formed with a center hole and an optical lens mounted on the bobbin via a thermal expansion adjustment memberformed with an opening. The optical lens has a substrate formed by an optical material different from the bobbin in coefficient of thermal expansion. The substrate has a convex part functioning as a convex lens and a flat part positioned around the convex part. The flat part is fixed to the thermal expansion adjustment member so that the convex part fits in the opening. The optical lens is placed so that a center axis of the convex part or an extension thereof passes through the center hole of the bobbin and the center axis of the convex part coincides with a center hole of the bobbin.
