20080252171Surface Acoustic Wave Motor - In an energy recovery type surface acoustic wave motor, an increase in energy efficiency at the time of energy recovery and supply is achieved by adjusting phase change. A surface acoustic wave motor comprises: a surface acoustic wave substrate; a slider provided with an applied pressure; a driving interdigital electrode connected to an external power supply for generating a driving surface acoustic wave on a surface so as to drive the slider by a frictional force which is generated on a contact surface of the slider with the surface acoustic wave substrate based on the surface acoustic wave and the applied pressure; recovery interdigital electrodes placed forward and backward in the direction of travel of the surface acoustic wave for recovering energy of a surface acoustic wave unused to drive the slider, and for using that energy to generate a surface acoustic wave; and phase adjusting means for matching the phase of a surface acoustic wave generated by the recovery interdigital electrodes to the phase of the driving surface acoustic wave W generated by the driving interdigital electrode.10-16-2008

20080306904SYSTEM, METHOD, AND PROGRAM PRODUCT FOR INTEGRATING DATABASES - A system for integrating databases comprises a first virtual table, a second virtual table, a common table, a list, a generating section, and a selecting section. The first virtual table corresponds to a first data. The second virtual table corresponds to a second data. The common table is associated with the first and second virtual tables. The list indicates information about associations between the first and second virtual tables and the common table. The generating section generates two or more access plans from a database query on the common table. The two or more access plans involve at least one of the first and second virtual tables in accordance with the list. The selecting section selects one of the two or more access plans generated by the generating section to be used to execute the database query.12-11-2008

20100278760Cosmetics - The cosmetic of the present invention is a cosmetic that alleviates skin irritation by blending in polypropylene glycol, a specific polar oil, or polybutylene glycol, as well as an ultraviolet absorbent. The present invention also relates to an agent and a method for alleviating irritation by lipophilic drugs. Since the present invention alleviates skin irritation due to ultraviolet absorbents and lipophilic drugs in cosmetics, any amount of ultraviolet absorbents and lipophilic drugs can be blended in cosmetics, and therefore cosmetics that can fully manifest their effects can be provided. Also, it is possible to prepare a safe sunblock cosmetic with superior ultraviolet protection effects because the ultraviolet absorbent is not absorbed through skin.11-04-2010
