This invention provides a way to control the tilt of optical disk for an optical disk device that can read and write on an optical disk. The control process includes: Optical pick-up 14, output signals of reflecting beams to a tilt detector 28. Tilt detector 28, sample-holds the signal level of reflecting beams of the write power before pits are formed, and outputs the signal level to a controller 20. The controller 20 changes the tile of the optical pickup 14 into three different states, and compares sample hold valves of each state, and adjusts the tilt to the state that generates the maximum signal level. Since the pits are not formed at that time, the signal of reflecting beams have not affected by pits, the signal level reflects only to the tilt of optical disk 10. This invention enables to control the tilt of the optical disk 10 precisely.

The invention provides a touch substrate and a touch device. The touch substrate comprises a substrate and a touch electrode structure, wherein the touch electrode structure is provided with a first transparent conducting layer and a second transparent conducting layer; the first transparent conducting layer is arranged on the substrate and is provided with a first side edge; the second transparent conducting layer is overlaid on the first transparent conducting layer; the first transparent conducting layer is provided with a first side surface which is positioned on the first side edge; the second transparent conducting layer is provided with a second side surface which is positioned on the first side edge; and the first side surface is provided with a first slope, the second side surface is provided with a second slope, wherein the absolute value of the first slope is greater than the absolute value of the second slope. By use of the touch substrate, the ray reflection amount of a touch sensing structure can be reduced so as to improve the visuality of the touch substrate and the touch device.

A display device includes a light-providing part, a first display panel part disposed at a first side of the light-providing part, a second display panel part disposed at a second side of the light-providing part, a receiving part disposed between the second display panel part and the light-providing part and a film member disposed between the second display panel part and the receiving part. The film member has an opening formed corresponding to the second display panel part. The film member reduces the amount of reflected light that is directed to the first side of the light-providing part. Thus, the display device has a simplified structure and improved display quality.

The invention discloses a darkening agent for nylon fabric and a preparation method thereof. The darkening agent was synthesized from organic dicarboxylic acid, epoxy double head, polyether amine, octamethylcyclotetrasiloxane and trifluoropropylmethylcyclotrisiloxane. The fluorine-containing polysiloxane segment in the molecular structure of the darkening agent provided by the invention can effectively reduce the amount of light reflection on the surface of the nylon fabric after finishing, thereby increasing its apparent depth. At the same time, the polyether segment in the molecular structure can Improve the hydrophilic property of nylon fabric after finishing. In addition, according to the principle of structural similarity, the polyamide segment in the molecular structure of the darkening agent can form a eutectic with the molecular segment of nylon (polyamide fiber) under high-temperature baking conditions, and the nylon fabric after finishing has a washable Enhanced effect.

A method for aligning a projected beam on a reflector in a reflective-type beam detector, the method including adjusting the projected beam so as to: project on to substantially all, if not all, of a reflective surface of the reflector; or project on to at least a portion of a reflective surface of the reflector until a constant, or within a predetermined threshold of a constant, signal is received from the reflector; and detecting one or more edges of the reflective surface of the reflector and thereby: centering the projected beam, so as to align an approximate center of the projected beam on, or within a predetermined threshold of, an approximate center of the reflective surface of the reflector; and / or determining a shape or profile of the reflector.
