摘要:
A method for making a thin wall component comprise: locating a film (40) in a mold cavity of a mold, wherein the mold cavity has an initial mold thickness, wherein the film comprises a base layer (41) and a pattern layer (42); injecting a molding material (60) into the mold cavity such that the molding material contacts the pattern layer, wherein the molding material comprises a polymeric material and a filler; compressing the mold to a final mold thickness that is less than the initial mold thickness, to form a molded product, wherein the pattern layer forms a surface of the molded product; and removing the molded product from the mold. A molded product formed by the method. The method produce a thin walled component without warpage, inner stresses, poor surface quality, or washout defects.

Disclosed herein are methods of inhibiting sperm motility. In some embodiments, a method of inhibiting sperm motility includes contacting a sperm with an effective amount of 3BP, thereby inhibiting sperm motility. Also disclosed herein are methods of contraception. In some embodiments, a method of contraception includes administering an effective amount of 3BP to the vagina so that sperm in contact with 3BP change their swimming patterns, which are incompatible with fertilization, thus preventing pregnancy. In one embodiment, a method includes topical application of 3BP to the penis in an amount effective to cause complete loss of motility of ejaculated sperm during sexual intercourse, thereby achieving contraception. In some examples, 3BP is administered as a spermicide in the forms of a jelly (gel), films, sponges, foams and timed-release mesh. In some examples, condoms are coated with 3BP-containing lubricant to achieve contraception.

Disclosed is a method for inputting and searching Chinese characters with Easy-Strokes, wherein the complex strokes of Chinese characters are broken down into simple strokes without any angle (or vertex) and a said simple stroke is identified as an Easy-Stroke. The feature information of Easy-Strokes for a Chinese character consists of the total stroke number of Easy-Strokes, the stroke types of Easy-Strokes, the stroke types of Easy-Strokes at the special locations of a character, and the stroke numbers of different types of Easy-Strokes. A correspondence is established between the feature information of Easy-Strokes and the corresponding input components on a device to implement the input of Chinese characters. A Chinese character database is established according to the feature information of Easy-Strokes to implement the search of Chinese characters. The present invention simplifies complex strokes of Chinese characters and enables users to easily input Chinese characters without memorizing a large number of complex rules, and basic knowledge of mapping between keyboard codes and root characters. In addition, its operation is simple and convenient because users may choose to input the feature information of Easy-Strokes for a Chinese character in any sequence and combination. Thus, both Chinese and non-Chinese can easily adopt the method.
