Abstract: A method for preparing an anodic aluminum oxide-based photonic crystal product includes: subjecting an aluminum-containing object to a first pretreatment; subjecting the aluminum-containing object to a first anodizing treatment by applying periodic current signals, so as to form first porous aluminum oxide films on the aluminum-containing object along a first direction, the first porous aluminum oxide films each including first nanopore structures; and subjecting the aluminum-containing object to a second anodizing treatment by applying a slowly increasing current signal, followed by constant current signal so as to form a second porous aluminum oxide film beneath an Nth first porous aluminum oxide film, the second porous aluminum oxide film including second nanopore structures. An anodic aluminum oxide-based photonic crystal product prepared by the method is also provided.

Abstract: A method for colorizing an aluminum-containing object includes the steps of: (a) subjecting the aluminum-containing object to a first pretreatment, so as to remove contaminants from a surface thereof; and (b) subjecting the pretreated aluminum-containing object obtained in step (a) to an anodizing treatment which is accomplished by applying N cycles of periodic current signals, thereby forming an aluminum oxide film with a plurality of nanopores on the surface of the aluminum-containing object. In step (b), each cycle of the periodic current signals includes a first to fourth predetermined time periods. A colorized aluminum-containing object prepared by the aforesaid method is also provided.

Abstract: A method for manufacturing a play-of-color article includes the steps of: (a) providing a first mixture that contains a solvent and a plurality of functionalized colloidal particles; (b) replacing the solvent of the first mixture with a polymer solution that contains polymers, thereby obtaining a second mixture; (c) adding an initiator to the second mixture to obtain a third mixture, followed by injecting the third mixture into a mold and disturbing the third mixture, so that the third mixture is formed with a pattern; (d) leaving the third mixture to stand, so as to allow the functionalized colloidal particles therein to self-assemble to form a crystalline arrangement, thereby obtaining a fourth mixture; and (e) subjecting the polymers in the fourth mixture to a cross-linking reaction, thereby obtaining the play-of-color article. A play-of-color article manufactured by the method, and a play-of-color product including the play-of-color article are also provided.

Abstract: This invention discloses a method of selective plastic insert molding on metal component and its product. A metal joint component is bonded with a metal component. After which, the joint component is submerged in plastic so that the molded plastic can be secured on the metal component firmly. Hence, a desired plastic structure can be formed on the metal component. This invention can shorten the manufacturing process and reduce the cost. In addition, it solves the traditional bonding problem between the plastic and the metal component as well as the problem concerning processing time and high cost.

Abstract: A monitor attitude adjustment apparatus used in an electronic apparatus comprises a mount base; an attitude adjusting mechanism consisting of a plurality of actuating devices, each actuating device comprising a driver and a displacement mechanism, the driver being the force source for driving the movement of corresponding displacement mechanism, and each displacement mechanism having a constrained degree of freedom for mechanical motion; and a suspension mount with one end mechanically connected to the attitude adjusting mechanism and the other end securing the electronic apparatus; wherein the actuating devices in the attitude adjusting mechanism constitute an integrated mechanical state and the position or orientation of the electronic apparatus corresponds to the integrated mechanical state of the attitude adjusting mechanism.

Abstract: The present invention relates to a cantilever structure of mounting frame that uses mainly the arc tracks of a first through-slot member and a second through-slot member on a flange to produce different tensile elongations of the elastic element such that the mounting frame can stay firmly at the adjusted position under the bearing created by different angles.

Abstract: The present invention relates to a mounting frame structure for flat panel display device that allows the user to conveniently mount or dismount a flat panel display device on or from a wall and adjust the tilt of the flat panel display device with ease to a degree comfortable for viewing by the user.

Abstract: An electrical connector (1) used in high frequency signal transmission filed includes an insulative housing (2), an immovable contact (5) retained in the housing. The immovable contact includes a main body (50), a cantilevered arm (51) longitudinally extending from the main body, a soldering portion (53) backwardly extending from the main body. The cantilevered arm forms an angle to the main body. The main body is a substantially “Z” shape to prolong the current path of the immovable contact and to cut the area of the immovable contact, thereby decreasing the capacity of the immovable contact.
