  • Patent number: 10435829
    Abstract: The invention relates to a method for making a spunbonded high loft nonwoven web comprising crimped multicomponent fibers, the process comprising continuously spinning the fibers, directing the fibers to a spin-belt by deflectors and/or air streams, laying down the fibers on the spinbelt and pre-consolidating the fibers after laydown using one or more pre-consolidation rollers to form a pre-consolidated web, wherein a first component of the fibers comprises a PP homopolymer and a second component of the fibers comprises a PP/PE copolymer, wherein the pre-consolidation rollers are operated at a temperature of smaller 110° C. and/or a linear contact force of smaller 5 N/mm.

  • Patent number: 9662837
    Abstract: The present invention relates to a method for printing a three-dimensional structure with a smooth surface comprising the following steps of depositing multiple droplets of printing material at least partially side by side and one above the other and curing the deposited droplets by light irradiation to build up a three-dimensional pre-structure in a first step, and smoothing at least one surface of the three-dimensional pre-structure by targeted placement of compensation droplets in boundary areas of adjacent deposited droplets and/or in edges of the surface to be smoothed in a second step to build up the three-dimensional structure with a smooth surface.

  • Patent number: 8481123
    Abstract: Novel methods and apparatuses for annealing semiconductor devices in a high pressure gas environment. According to an embodiment, the annealing vessel has a dual chamber structure, and potentially toxic, flammable, or otherwise reactive gas is confined in an inner chamber which is protected by pressures of inert gas contained in the outer chamber. The incoming gas delivery system and exhaust gas venting system are likewise protected by various methods. Embodiments of the present invention can be used, for example, for high-K gate dielectric anneal, post metallization sintering anneal, and forming gas anneal in the semiconductor manufacturing process.

  • Patent number: 8173059
    Abstract: A method of manufacturing an article using stereolithography in which the article includes at least one feature that defines an isolated volume is described. The method includes the step of forming one or more removable structures within said isolated volume from cured resin during the stereolithography process. The removable structures restrict the flow of liquid resin within said isolated volume.

  • Patent number: 6451240
    Abstract: A microneedle array is manufactured using a mold preparation procedure that begins by placing an optical mask over a layer of PMMA material, exposing the PMMA material to x-rays, then developing using a photoresist process. The remaining PMMA material is then electroplated with metal. Once the metal has reached an appropriate thickness, it is detached to become a metal mold that is used in a microembossing procedure, in which the metal mold is pressed against a heated layer of plastic material. Once the mold is pressed down to its proper distance, the plastic material is cooled until solidified, and the mold is then detached, thereby leaving behind an array of microneedles.

  • Patent number: 4722815
    Abstract: A synthetic resin product contains various substances such as perfumes, insectifuges/insecticides, mold/mildew-proofing agents and anti-fungi agents which are inactivated by forming an inclusion compound thereof in cyclodextrin and coating them with glycitol(s) to thereby prolong the duration period of the substance. A process for the production of the same is further disclosed wherein the glycitol is provided in the form of reduced millet jelly or reduced cyclodextrin millet jelly.
