TWO-SIDED FIXING STRUCTURE, EXHIBITING OR INDICATING APPARATUS USING SAME, DUST COLLECTING APPARATUS, AND PLANT GROWING APPARATUS

摘要

Provided is a two-sided fixing structure that can be repetitively used with extreme ease, has neither any problems of wasting materials nor any problems of energy and that can be applied to various usages, such as an exhibiting or indicating apparatus and a dust collecting apparatus.  A two-sided fixing structure comprises an electrostatic chuck unit (2) and a power supply unit (5).  The electrostatic chuck unit (2) has a dielectric member (3) that is made of an insulating material and shaped like a flat plate and that has two sides, i.e., front and back sides; and internal electrodes (4) that are embedded within the dielectric member.  It is arranged that when the power supply unit (5) applies a voltage to the internal electrodes (4) of the electrostatic chuck unit (2), the two sides of the dielectric member serve as respective fixing surfaces.  The power supply unit (5) has a solar cell (6) and a boosting circuit (7) that boosts a power generated by the solar cell (6).  An Exhibiting or indicating apparatus has a display means that is formed by use of the two-sided fixing structure for an exhibition or indication purpose.  A dust collecting apparatus has a dust collecting means that is formed by use of the two-sided fixing structure.  A plant growing apparatus is formed by use of the two-sided fixing structure.
