摘要:
The present invention provides a method for improving cognitive performance that encompasses all of: sense; perception; recognition; judgment; and action or suppression; and is based on a higher brain function. The method for improving cognitive performance of the present invention includes administering astaxanthin and/or an ester thereof to an individual. The cognitive performance is, for example, at least one selected from the group consisting of judging ability, spatial attention-allocating ability, concentration on the recognition of surroundings, and agility as determined by speed and/or accuracy of a body reaction which requires a higher brain function.

Embodiments of the present disclosure may include a piezoelectric pump having: a piezoelectric vibrator including a main shim that may be formed of a conductive thin metal plate and a piezoelectric element layer that may be formed on the main shim; and a pair of ring-shaped support members that may support front and rear sides of a circumferential portion of the piezoelectric vibrator such that a pump chamber and an air chamber formed on the front and rear sides of the piezoelectric vibrator may be fluid-tightly sealed. The ring-shaped support members may support both sides of a circumferential portion of the piezoelectric element layer of the piezoelectric vibrator, and the piezoelectric vibrator may be vibrated to perform a pumping operation.

A piezoelectric pump includes a piezoelectric vibrator whose periphery is fluid-tightly sealed, and a pump chamber and an air chamber that are formed on front and rear sides of the piezoelectric vibrator. The piezoelectric pump vibrates the piezoelectric vibrator to perform a pumping operation. The piezoelectric vibrator includes: a shim that is formed of a conductive thin metal plate and has one surface abutting on the pump chamber; and a laminate of a plurality of piezoelectric element layers that is formed on the other surface of the shim so as to face the air chamber or the pumping chamber. The plurality of piezoelectric element layers are polarized and connected to wiring lines such that the amplitude of the vibration of the piezoelectric vibrator is larger than that of a piezoelectric vibrator including a single-layer piezoelectric element.

Providing an information recording member resin-enclosed tag and its manufacturing method, which can form various tags, expand choices available to attaching methods for articles to be attached, and prevent an information recording member from being affected by dirt. The tag comprises a resin substrate having at least a recording member, and an outer packaging body formed by an injection molding using a resin to be fusion-bonded to the substrate, wherein the recording member is covered with the substrate and packaging body. The tag is manufactured by: forming a substrate in advance by a resin; disposing at least a recording member on the substrate; disposing the substrate having the recording member, inside a cavity of a die which shapes an outer packaging body for covering the member by the molding; and making a fusible resin fusion-bonded to the substrate flow in the cavity to form the body covering the member.

A vibratory gyroscope including a planar elastic vibrator having vibrator piezoelectric material layers formed on both the front and back sides. The vibrator includes a base portion and three parallel elastic pieces extending from the base portion such that the a center elastic piece is located between two side elastic pieces. Electrode layers are formed over the piezoelectric material layers which cause both the side elastic pieces and the center elastic piece to vibrate in a plane, such that the vibrations of the center elastic piece are 180.degree. out-of-phase with the side elastic pieces. When the thus-vibrated vibrator is rotated, the elastic pieces are vibrated in directions parallel to the plane due to the Coriolis force. These deformations are detected as voltage changes across the piezoelectric material layers, and the voltage changes are used to determinate the angular velocity of the vibrator. The outside edges of the side elastic pieces are offset from an outer edge of the base section to prevent twisting stress, thereby allowing more precise vibration detection.

The capacitor satisfies the standard temperature dependence of capacitance and shows a minimized change of capacitance with time under an applied DC electric field and a long insulation resistance life. Where the dielectric layers contain 0.1-3 mol of MgO, 1-5 mol of Y.sub.2 O.sub.3, 2-12 mol of BaO+CaO, and 2-12 mol of SiO.sub.2 per 100 mol of BaTiO.sub.3, the capacitor shows improved DC bias performance.
