Abstract: A method for controlling surface asperity during laser sealing of a membrane vent hole. The method includes applying a main pulse from a main laser to the membrane vent hole at a first time. The main pulse has a main pulse cross-sectional shape, a main pulse power profile, and a main pulse duration. The method further includes applying one or more supplemental pulses from one or more supplemental lasers to the membrane vent hole at a second time later than the first time. The one or more supplemental pulses have supplemental pulse cross-sectional shape(s), supplemental pulse power profile(s), and supplemental pulse duration(s). The first and second applying steps form a seal over the membrane vent hole. The seal includes a seal surface having a controlled surface asperity characteristic.

Abstract: Methods of sealing a venthole of a micromechanical device. The venthole leads to a chamber that contains a device. A first laser pulse is applied to the venthole of a substrate of the micromechanical device for a first time period. The first laser pulse has a first laser intensity spatial distribution. Thereafter, a second laser pulse is applied to the venthole for a second time period. The second laser pulse has a second laser intensity spatial distribution that is different than the first laser intensity spatial distribution. The second laser pulse can be applied for a time that is different than that of the first laser pulse.

Abstract: The present embodiments disclose processes for preparing a polyester latex containing an amount of residual organic solvent which is less than 100 ppm by weight of the total weight of the polyester latex.

Abstract: A process and system for continuously making a resin emulsion suitable for use in forming toner particles includes at least one micromixer for micromixing a resin mixture and aqueous phase to continuously produce an emulsion of a high solids content. The process comprises contacting a polyester resin possessing acid groups with a component selected from the group consisting of an organic solvent and a solvent inversion agent to form a resin mixture; neutralizing the resin mixture with a neutralizing agent; and subjecting the resin mixture to micromixing.

Abstract: Improved methods for making hole transport molecules (HTMs) that are incorporated into imaging members, such as layered photoreceptor devices, to increase the photoreceptor's “hole mobility,” or its ability to move charge, across its charge transport layer (CTL). Embodiments pertain to a continuous process for making N,N-diphenyl-4-biphenylamine and a system for performing the same.

Abstract: Apparatuses and methods for preparing sol-gel solutions are provided. Specicifically, apparatuses include a vessel optionally containing a stirrer; a pump; a fluidized bed reaction column; and multiple fluid lines. The multiple fluid lines connect the vessel and the pump in a first circulation loop and connect the vessel, the pump and the fluidized bed reaction column in a second circulation loop.
