Abstract: A camera front cover includes an outer frame, a supporting ring inside the outer frame, an annular light-penetrable part, and a central light-penetrable part connected to and between the outer frame and the supporting ring. The central light-penetrable part is connected to the inner side of the supporting ring. The outer frame or the supporting ring includes two blocking structures, which extend parallel to an axial direction of the camera front cover to correspondingly block a fringe of the annular light-penetrable part or the central light-penetrable part correspondingly. A camera includes a device outer casing, an image-capturing device, and the camera front cover. The camera front cover is connected to the device outer casing to form an accommodating space in which the image-capturing device is disposed. A lens of the image-capturing device faces the central light-penetrable part and captures external images through the central light-penetrable part.

Abstract: A milling cutter is used for processing a metal substrate and includes a handle and a cutting portion. The cutting portion extends outward from one end of the handle. The cutting portion includes at least two opposite spiral guiding grooves. A cutting knifes is provided on one side of the guiding groove. The cutting knife has a spiral angle with range between 35°˜45° and the cutting portion is coated with a coating layer on surface thereof. The surface hardness, lubrication and scouring removing ability are enhanced. The abrasion and heat pipe for the cutting knifes 23 and 24 can be eliminated.

Abstract: A drilling pin for machining metal substrates includes a drillstock, a drill bit, and a coating. The drill bit extends from an end of the drillstock, and includes at least two corresponding helix guide grooves. Two knife-edges are formed/defined between the at least two helix guide grooves. A helix angle defined by an axis of the drill bit and a tangent of the two knife-edges is in a range from about 15 degrees to about 35 degrees. The coating is formed on a surface of the drill bit. Thus, strength, lubricity, scraps discharge performance of the drilling pin have been greatly improved, and abrasion and thermal budget phenomena can be decreased. Therefore, the service life of the drilling pin can be greatly extended.

Abstract: A light device with a color mixing effect, includes a first light bar, a second light bar, and a holding structure. The first light bar emits a first color light with a first color, and the second light bar emits a second color light with a second color different from the first color.

The first positioning portion is for positioning the first light bar, the second positioning portion is for positioning the second light bar, and the first light bar is parallel to and obliquely faces the second light bar, such that the first color light and the second color light are respectively emitted into the light-mixing area to form a third color light with a third color different from the first color and the second color.

Abstract: A magnetic filter for physical vapor deposition equipment is disposed at the exit of a sputtering target. The magnetic filter includes a pipe and a magnetic field generator. The pipe includes an entrance end, an exit end, and at least a crooked portion formed between the entrance end and the exit end. The entrance end is connected to the exit of the sputtering target. The particle size of the metallic ions sputtered from the sputtering target that can pass the pipe is controlled by the intensity of the magnetic field generated from the magnetic field generator. In this manner, the nanometer particles and the micrometer particles sputtered from the sputtering target can be separated. Only the nanometer particles can pass through the pipe and be coated on the sample surface. This will enhance the structural strength and mechanical properties of the coated film, and extend the life expectancy of the coated sample.
