Abstract: A wind vane device comprises a horizontal portion that can swivel by the propeller blades provided at one end, a vertical portion with one end attached to the bottom of the horizontal portion and the other end extending downwardly, a supporting frame supporting the horizontal portion at the lower side of the vertical portion, wherein the vertical portion is cylindrical and has a plurality of radial partitioning walls at inner side in the axial direction; an upright shaft having an axle 51 with thread portions at both ends, one end of which is fastened to the center of the partitioning wall and the other end provided with a pair of bearings, a bearing sleeve being put around the outside of the pair of bearings; wherein the supporting frame consists of several sections of supporting rods. An engageable and disengageable structure is formed between a supporting rod and a supporting rods through a connector. The upper end located at the supporting rod of top-section engages at the outside of the bearing sleeve.

Abstract: The present invention relates to an opportunity-based ordering platform system. By applying the steps of the present invention, the seller's capability is more competitive and the buyers have an opportunity to purchase goods with a lower price. The system comprises a red tag goods bidding platform, a blue tag goods redeem platform, a membership system, and a charging system. Wherein, the red tag goods bidding platform mainly provides the product catalogs, the goods bidding closing time, the interval number of the good's bidding, and the red tag points that should be deducted when placing the bid, as well as the function for the buyers to place the bid. After the goods bidding is closed, the system searches and selects a bid order that has a unique bid interval number and assigns the owner of that bid order as both the bid winner and the lucky draw winner. The lucky draw winner can purchase the goods with only 10% of the product's current market price.

Abstract: An integrated circuit wafer protective container for containing IC wafers during the process of IC wafer fabrication is disclosed. The protective container comprises a wafer-containing member and a wafer-protecting and securing member. The wafer-containing member is of a substantially cylindrical shape of a tube having a closed end and an open end. The inner diameter of the wafer-containing member is suitable for containing the IC wafers. The wafer-protecting and securing member is of a substantially cylindrical shape of a tube having a closed end and open end. The inner diameter of the wafer-protecting and securing member is suitable for receiving the cylindrical body of the wafer-containing member. The wafer-protecting and securing member has a number of latching protrusions formed at its open end on the inner side wall of its cylindrical shaped tube. The wafer-containing member has a number of latching slots formed at its closed end on the exterior surface of its cylindrical shaped tube.
