  • Patent number: 10947632
    Abstract: A method of additive manufacturing that deposits material onto a cathode by transmitting current from an anode array through an electrolyte to the cathode; the method uses feedback to control the manufacturing of successive layers of a part. For example, feedback signals may be a map of current across the anode array; this current map may be processed using morphological analysis or Boolean operations to determine the extent of deposition across the layer. Feedback data may be used to determine when a layer is complete, and to adjust process parameters such as currents and voltages during layer construction. Layer descriptions may be preprocessed to generate maps of desired anode current, to manipulate material density, and to manage features such as overhangs. Feedback signals may also trigger execution of maintenance actions during the build, such as replenishment of anodes or removal of films or bubbles.

  • Patent number: 10941056
    Abstract: A water treatment device in which a treatment target water introduction portion is provided in an upper portion of a receptacle, and the water treatment device has a space in which conductive porous members are not disposed between the conductive porous members and the treatment target water introduction portion in the receptacle. When a backwashing fluid is introduced from a lower portion of the receptacle in a desorption, the conductive porous members flow and are agitated owing to the backwashing fluid, because of which a desorption of ions adsorbed to the conductive porous members is promoted. Grains of the agitated conductive porous members collide with other grains of the conductive porous members or with electrodes or a separator, whereby scale and a biofilm appearing on surfaces of the grains of the conductive porous members, the electrodes, or the separator can be removed, and desalination efficiency can be maintained.

  • Patent number: 10927472
    Abstract: A method of forming a micro-structure involves forming a multi-layered structure including i) an oxidizable material layer on a substrate and ii) another oxidizable material layer on the oxidizable material layer. The oxidizable material layer is formed of an oxidizable material having an expansion coefficient, during oxidation, that is more than 1. The method further involves forming a template, including a plurality of pores, from the other oxidizable material layer, and growing a nano-pillar inside each pore. The nano-pillar has a predefined length that terminates at an end. A portion of the template is selectively removed to form a substantially even plane that is oriented in a position opposed to the substrate. A material is deposited on at least a portion of the plane to form a film layer thereon, and the remaining portion of the template is selectively removed to expose the nano-pillars.
