  • Publication number: 20240133038
    Abstract: Methods of forming a structural color metal-dielectric-metal (MDM) component via a solution-based process are provided. First, a first metal layer is formed over a treated surface of a substrate by a first electroless deposition process. A surface of the treated substrate is contacted with a first plating bath that comprises a metal selected from the group consisting of: copper, aluminum, silver, alloys, and combinations thereof. A dielectric layer, for example, comprising silicon dioxide, is then deposited over the first metal layer by a sol-gel process. Next, the method comprises forming a second metal layer over the dielectric layer by a second electroless deposition process by contacting the dielectric layer with a second plating bath having a neutral pH and comprising a metal selected from the group consisting of: copper, aluminum, silver, alloys, and combinations thereof.

  • Patent number: 11368122
    Abstract: The present invention discloses an anti-stalling circuit, an anti-stalling system composed of same and an anti-stalling method. The anti-stalling circuit includes a motor main circuit and a control circuit; the anti-stalling system includes a substrate rotating synchronously with a passive end and the passive end anti-stalling circuit, the substrate is provided with a notch, the angle of the notch ranges from 150° to 170°, and the proximity switch SQ1 and the proximity switch SQ2 are installed at 180° on both sides of the substrate; and the passive end anti-stalling method is applied to the passive end anti-stalling system. The present invention can greatly reduce the probability of major failures caused by the stalling of a passive end of drive equipment at a limited cost.
