The first substrates in the second chamber are sputtered. The second carriers in the first chamber and the first carriers in the second chamber are exchanged. The first substrates in the first chamber are taken out.

Abstract: An optical element includes a substrate and an anti-reflective unit provided on one surface of the substrate. The anti-reflective unit includes a first coating layer, a second coating layer, a third coating layer, a fourth coating layer, and a fifth coating layer arranged on the substrate sequentially. The thickness of each of the first coating layer, the third coating layer, and the fifth coating layer is in the approximate range from 6 to 100 nanometers, and the thickness of each of the second coating layer and the fourth coating layer is in the approximate range from 10 to 200 nanometers. The first coating layer, the third coating layer, and the fifth coating layer are made of SiO2, and the second coating layer and the fourth coating layer are made of TiO2. The optical element can provide a high rate of light transmission.

Abstract: A lens includes a central optical portion, a peripheral portion surrounding the central optical portion, a first ZnS coating formed on the central optical portion and the peripheral portion at one side of the lens, and a first MgF2 coating formed the central optical, the peripheral portion being free of MgF2 coating formed thereon. The optical thickness of the first ZnS coating is one quarter of a wavelength of predetermined light passing therethrough. The optical thickness of the first MgF2 coating is one quarter of the wavelength of the predetermined light.

Abstract: An exemplary multi-layer film includes a top layer, a bottom layer and medium layer. The top layer is configured for reflecting part of incident light to be a first reflected light and allowing another part of the incident light to transmit therethrough. The bottom layer is capable of clinging to the substrate, and is configured for reflecting the transmitted light to be a second reflected light. The medium layer is sandwiched between the top layer and the bottom layer, and is configured for controlling a light path difference between the first reflected light and the second reflected light, such that the first and second reflected lights interfere with each other and provide the multi-layer film with a desired color appearance.

Abstract: A grinding apparatus for grinding workpieces includes two clamping rods and a base. Each of the two clamping rods has a first end and an opposite second end. The first ends are opposite to each other for clamping workpieces therebetween. The base includes a receiving groove for receiving the workpieces therein and two positioning slots at opposite sides of the receiving groove. The positioning slots are aligned with each other and configured for receivingly engaging with the clamping rods to align the clamping rods with each other.

Abstract: A multilayer substrate includes a base layer, a coating layer and an intermediate layer positioned between the base layer and the coating layer. The intermediate layer contains chromium and nitrogen. A content of the chromium in the intermediate layer gradually decreases from the base layer to the coating layer.

Abstract: The present invention discloses a method for forming a composite membrane with a porous coating layer. At first, a filling process is carried out to fill the pores of a porous substrate with a liquid. Next, a raw material is transformed into melt or incomplete melt droplets by a heating source and the droplets are sprayed to the surface of the porous substrate filled with the liquid. The liquid is evaporated by the high temperature droplets and plasma flame to become vapor and the vapor breaks through the droplets to have the droplets sputter into different blocks to thereby form random and dispersed flat particles after cooled. Flat particles are formed and stacked continuously so as to form a composite membrane with a porous coating layer. Moreover, the invention provides an apparatus for forming a composite membrane with a porous coating layer.

Abstract: A light guide plate, for use with a back-light module for seasonal scanning in dividing zones, includes a light-pervious substrate having a plurality of dividing blocks formed thereon, an optical grating structure disposed on light incident surface of each of the dividing blocks for allowing light to enter, and a light diffusion structure disposed on an optical surface of each of the dividing blocks for diffusing the light. As the light-pervious substrate is adapted for seasonal scanning in different zones, the provision of the optical grating structure can shorten the light mixing distance while the light diffusion structure can evenly emit and spread the light throughout the light guide plate to solve the drawbacks of the prior techniques. Further, a back-light module having the light guide plate is provided.

Abstract: A system and method for managing network devices via e-mail that accomplishes sending management commands to the management proxy device (140) and receiving status information on the managed device (150) via e-mail in a network management system. The system for managing network devices via e-mail comprised: at least one management base (100) that runs an e-mail client side program (113) as a network management tool to send e-mails containing management commands; at least one management proxy device that runs an e-mail service module (146) for receiving and analyzing e-mails containing management commands, and for sending e-mails containing status information on a managed device, said e-mail service module comprising an e-mail receiving sub-module (1461), a decryption sub-module (1462), a status information reporting sub-module (1463) and an e-mail sending sub-module (1464); and an e-mail server (160) that receives e-mails from the management base and the management proxy device.
