Abstract: A tray structure includes a plurality of trays stacking together from top to bottom and expanding in an alternating manner to construct a spiral plant tower. Each of the trays includes a bottom plate, a peripheral wall and a cultivating space. Each of the trays includes an inner tube provided with a protruding locking member, and an outer tube provided with a plurality of recessed locking members. The recessed locking members of the outer tube of an upper one of the trays are locked onto the protruding locking member of the inner tube of a lower one of the trays. Each of the trays includes a connecting tube located in and connected with the inner tube by a plurality of separating ribs. The connecting tubes of the trays are juxtaposed to each other when the trays are combined together.

Abstract: A casing molding method includes following steps: providing a substrate; mixing the substrate, first hardener, second hardener, and epoxy resin in a mold to perform a first curing reaction to form a semi-manufactured product, wherein the first hardener is coated by micro capsules; and heating the semi-manufactured product to make the micro capsules ruptured and vaporized, and the first hardener contacts with the semi-manufactured product to perform a second curing reaction to form a casing.

Abstract: A rigid reinforced composite material includes a plurality of first material layers. Each first material layer has a first texture. The first material layers are stacked, and the first textures are not all in parallel in the projection direction. In addition, a method of making the rigid reinforcing composite material is disclosed. Accordingly, the composite material having high rigidity and high strength can be fabricated by the simple and efficient manufacturing process, and the device using the composite material can be thinner and lighter.

Abstract: A method for manufacturing a housing is provided. A fiber film is placed on a first mold, and a second mold presses the fiber film to make it deform slightly. When the first mold and the second mold are not closed completely, the melt plastic material is injected from the second mold to the fiber film to press down the fiber film. Then, the molds are assembled while the melt plastic material is injected to form a molding product. Furthermore, the edge of the fiber film near the corner is cut off to obtain a housing with a well-attached fiber film.

Abstract: A casing of an electronic device and a manufacture method thereof are disclosed. A thin film with a protecting film is provided in a mold. Plastic is injected into the mold from an injection inlet of the mold to form the casing, and the location of the protecting film corresponds to that of the injection inlet. After the casing is formed, the protecting film and the plastic are molded integratedly.

Abstract: A method for fabricating a housing of an electronic device is provided. The method includes the steps of providing a bamboo laminate first, forming a recess on the bamboo laminate, performing an embedding injection molding process to form a supporting element made of high polymer in the recess and performing a cutting step to cut the bamboo laminate to have a predetermined thickness.

Abstract: The present invention provides a fabricating method for a cover of a portable electronic device. The fabricating method includes the following steps of: (a) providing a chunk of timber laminate having an exterior circumferential surface, a first surface, and a second surface, and forming a recess on the second surface; (b) attaching a supporting component into the recess; and (c) cutting the first surface and the exterior circumferential surface to a preset thickness; wherein the first surface and a portion of the exterior circumferential surface expose different woodgrain patterns. A portable electronic device utilizing the above mentioned fabricating method for a cover is also provided.

Abstract: An ejectable stand for a portable media center includes a stand body and a slide switch. The stand body has a front end, a rear end and an outer surface, and the rear end has a torsion spring pushing against both the stand body and the portable media center, and the front end has a stop. The slide switch slidably is mounted on the outer surface of the stand body and has a fastening hook corresponding to the fastening lip of the portable media center, and the fastening hook includes a compression spring pushing against both the fastening hook and stop of the stand body. The compression spring provides an elastic force to drive the fastening hook to slide the slide switch on the stand body and to fasten the fastening hook and the fastening lip together.
