  • Publication number: 20240069452
    Abstract: Embodiments of the present disclosure relate to projection stabilization systems and maskless lithography systems having projection stabilization systems. The projection stabilization system compensates for propagating vibrations that move image projection systems (IRS's). The IRS's are in a processing positon prior to operation of the maskless lithography process. One or more stiffeners are coupled to the IPS. The one or more stiffeners apply pressure to flexures coupled to each stiffener. The flexures are coupled to the IPS to provide stabilization to the IPS during the operations of the maskless lithography process. For example, the one or more of stiffeners protect the IPS from vibrations that propagate through the system during operation.

  • Publication number: 20240001318
    Abstract: A continuous process for producing a material of a battery cell using a system having a mist generator, a drying chamber, one or more gas-solid separators and a reactor is provided. A mist generated from a liquid mixture of two or more metal precursor compounds in desired ratio is dried inside the drying chamber. Heated air or gas is served as the gas source for forming various gas-solid mixtures and as the energy source for reactions inside the drying chamber and the reactor. One or more gas-solid separators are used in the system to separate gas-solid mixtures from the drying chamber into solid particles mixed with the metal precursor compounds and continuously deliver the solid particles into the reactor for further reaction to obtain final solid material particles with desired crystal structure, particle size, and morphology.
