This utility model discloses a type of baseball bat that falls within the baseball paraphernalia and is composed of a hitting part and a handle part; the inside of the hitting part is a hollow cavity, and the hitting—part wall body is of unequal wall-thickness construction. Different sections of the hitting part may hit the baseball when hitting. The wall body of hitting part is of an unequal wall-thickness construction, therefore, different resilience effect may be achieved by the hitting part with different wall thickness, the hitting effect of each stroke is different, and the pitch of baseball achieved by baseball bat makes it hard for an attacker to catch the baseball.

A polymer film without cholesteric liquid crystal (LC) is characterized in that the polymer film has photonic crystal structure. The polymer film is an innovative product in the feature of having photonic crystal structure without containing cholesteric LC. In addition, the polymer film can further contain fluid which is filled in the film body of the polymer film. By filling any of various fluids in the film body, the light of different wavelengths can be reflected by the polymer film based on Bragg reflection, so that the applications of the polymer film can be broadened. Especially when the fluid is anisotropic liquid, the polymer film can be applied to electro-controlled reflective display modules. In addition, stacking the imprinted polymer films manufactured from left-handed and right-handed cholesteric liquid crystals can improve the brightness of reflected light.

A manufacturing method of a polymer film with the photonic crystal structure includes a mixing step for at least mixing an achiral liquid crystal (LC), a chiral dopant, a monomer and a photo initiator together to form an LC-monomer mixture, at least one exposure step for exposing the LC-monomer mixture through a mask, at least one diffusion step for diffusing the monomer from the area around one of the exposure areas to the exposure area, and a LC removing step for removing the achiral LC to form the polymer film. By implementing the diffusion step after the exposure step, the polymerization rate of the monomers is enhanced so as to increase the proportion of the polymer in the polymer film and raise the imprint rate of chirality. Therefore, the polymer film can reveal stronger photonic crystal structure and property of Bragg reflection when it is not filled with any fluid.

A reduction gear includes a case including a hollow cylinder having teeth on its inner wall; a ring gear having outer teeth meshed with the teeth of the cylinder, and inner teeth; and an eccentric gear assembly mounted in the cylinder and including a hollow eccentric shaft including rear and front eccentric sections, and first and second gears rotatably secured onto the rear and front eccentric sections respectively. Rotating an input shaft in a first speed will rotate the eccentric shaft to rotate the first and second gears around the inner teeth of the ring gear eccentrically, thereby rotating the output shaft in a second speed lower than the first speed. The invention has an increased number of meshed teeth between each of the first and second gears and the ring gear so as to distribute a radial load to more teeth in rotation.
