Abstract: A functional patch for use with a contact lens includes an attaching layer and a functional patterned layer. The contact lens and the attaching layer are made of different hydrophilic materials to present two net-like structures respectively contain a plurality of first pores and second pores, and the second pores have pore size smaller than that of the first pores. The attaching layer is adsorbable to and detachable from the contact lens. A part of the functional patterned layer permeates into the second pores and the remaining part of the functional patterned layer is cured on the surface of the attaching layer. The attaching layer has closely arranged molecular chain blocks to form net-like structure having relatively small pore size. Therefore, only a limited amount of the material molecules of the functional patterned layer is permeated into the second pores, allowing the functional patterned layer to have a smooth surface.

Abstract: A color image patch for use with contact lens includes an attachment layer having one side for adsorbing to a surface of a contact lens, and an image layer connected to another side of the attachment layer and having an ornamental design provided thereon. Before wearing the contact lens, a wearer first selects a color image patch with favorite ornamental design and then attaches the attachment layer of the color image patch to the surface of the contact lens. The ornamental design on the image layer of the color image patch being adsorbed to the contact lens is located at a position corresponding to a wearer's iris and capable of changing the shape, size and color of the wearer's iris without influencing the vision correction function of the contact lens. Therefore, the color image patch gives the contact lens additional function and increased usefulness.

Abstract: A wire connector includes a connection box having two closed end walls spaced in a longitudinal direction. The connect box includes a compartment having first and second end walls spaced in a height direction. At least one partitioning wall extends from the second end wall toward but spaced from the first end wall, defining a gap. The at least one partitioning wall divides the compartment into a plurality of channels spaced in a width direction. The channels are respectively aligned with and in communication with through-holes in at least one of the closed end walls. Each channel has a first end at the first end wall and a second end at the second end wall. The first ends of the channels and the gap together define a flat receiving groove in which a conductive plate is received. An elastic pressing plate is received in each channel.

Abstract: A method of manufacturing color contact lens includes the steps of providing a rubber pad having a pressure bearing surface and filling C/M/Y/B coloring agents in a first inkjet printer; causing the first inkjet printer to jet the C/M/Y/B coloring agents on the pressure bearing surface of the rubber pad to form a color image layer; transferring the color image layer from the rubber pad onto an inner surface of a concave mold; injecting a lens material into the concave mold; pressing a convex mold against the concave mold to form a lens layer on the color image layer; and curing the color image layer and the lens layer to form a color contact lens. With the method, the color image layer can be formed using the inkjet printer without an increased thickness, enabling mass production of relatively thin color contact lenses at shortened time and lowered defect rate.

Abstract: A hollow toy structure includes at least a first and a second shell portion, which are configured as two three-dimensional concave members with their rims forming two mating joining surfaces, which can be assembled to each other for closing the first shell portion to the second shell portion to form a hollow body. On and along the joining surface of the first shell portion, there is provided at least one annular groove as a first coupling structure, which is located between an outer and an inner surface of the first shell portion; and on and along the joining surface of the second shell portion, there is provided at least one retaining ring as a second coupling structure for complementarily engaging with the annular groove. And, a bonding layer is applied on between the joining surfaces of the first and second shell portions to bond the two shell portions together.

Abstract: A cable connecting terminal has a conductive column in a terminal box, a plurality of plurality of steel elastic sheets around the conductive column, and arc slots on the conductive column corresponding to the plurality of steel elastic sheets. A conductive end of the cable inserted into the terminal box through the first or second cable hole, the conductive end of the cable is pressed by the pressing portions of the plurality of steel elastic sheets and tightly contacts the arc slot of the conductive column and is secured by the one-way securing portions of the plurality of steel elastic sheets.
