A flow guide directs a fluid flow across a surface of a device, for example a lens surface of an endoscope, in a controlled manner to facilitate flow attachment to the surface. Embodiments include features that impart a non-uniform velocity profile and/or include guide surfaces for facilitating flow attachment and/or coverage.

The invention discloses a process for manufacturing a veneer by using calcium silicate as a substrate, belonging to the method for processing the veneer. The process uses the wood-based panel as the substrate and comprises the following steps: A, producing facing paper: immersing the printed facing paper into a prepared liquid adhesive for adhesive coating, and drying the facing paper for later use, wherein the proportion of the amount of adhesive on the surface of the facing paper coated with the adhesive to that of the adhesive on the surface of the facing paper uncoated with the adhesive is (1.5-1.9):1; and B pre-treating the calcium silicate substrate: grinding and polishing the surface of the calcium silicate substrate, removing the impurities on the surface of the calcium silicate substrate, making liquid adhesive permeate from the surface of the calcium silicate substrate, and drying the calcium silicate substrate for later use. The process for manufacturing the veneer by using calcium silicate as the substrate is simple, is less restricted by the manufacturing environment and has a wide range of application.

A polymeric injection mold has stationary and movable parts of a mold mating at a parting line. The polymeric part has one or more re-entrant surfaces on both sides of the parting line, wherein the re-entrant surfaces are defined by slide bar projections inserted into the mold. During mold separation the slide bar projections are displaced towards a centerline of the mold to clear the re-entrant surfaces. The slide bar projections are attached to slide bars that pass through tapered slots in the side walls of the stationary and movable sides of the mold and are inclined at an angle to the centerline of the mold. The slide bars of the stationary side of the mold are removably connected to pull bars, wherein the pull bars are rigidly attached at their opposite ends to the movable side of the mold. When the movable side of the mold is withdrawn, the injection molded part is pulled out of the stationary side of the mold and the slide bar projections in the stationary side clear the re-entrant surfaces. The slide bars in the movable side are cleared from the re-entrant surfaces by moving the slide bars located on the movable side of the mold through the use of an ejector plate.
