Patent number: 11602875Abstract: A mold unit (30) defines an elongate cavity (70) and has an injection inlet port (90) for a viscous material at one end of the cavity and an injection outlet port (92) at the other end of the cavity. The mold unit includes a gas vent formed by a gap (G2) between two parts of the mold unit. The gap extends continuously or intermittently in the length direction of the the mold unit, while penetrating through the mold unit in the thickness direction such that it provides fluid communication between an interior space and an exterior space of the cavity. The gap is shaped such that, although gasses pass through, the viscous material does not pass due to fluidity resistance of the viscous material resulting from its viscosity. As a result, the gas vent acts to block leakage of the viscous material while permitting degassing of the viscous material.Type: GrantFiled: December 5, 2017Date of Patent: March 14, 2023Assignee: KAGA WORKS CO., LTD.Inventors: Osamu Mizoguchi, Hitoshi Tsujikawa, Kyota Imai

Patent number: 11592171Abstract: A method for making continuous encapsulated linear lighting is disclosed. In this method, a PCB is placed within a channel, and the channel is dammed by one or more stoppers. The dammed segment is filled and then caused or allowed to cure. The stoppers are then removed from their initial positions and moved along the channel. If one runs out of channel before the desired length of linear lighting is achieved, a second piece of channel is abutted to the previous segment of channel, the PCB is laid into it, and a segment is dammed, filled, and cured. The process continues iteratively until the desired length is achieved or more channel is required. The PCB may initially be cut to the full desired length and applied to the channel piecewise as needed.Type: GrantFiled: August 26, 2021Date of Patent: February 28, 2023Assignee: Elemental LED, Inc.Inventor: Brian McKay

Patent number: 11407159Abstract: The present invention is a method that enables continuous injection molding of a thermosetting resin composition and reuse of an unnecessary part produced during the molding. The method includes injecting a thermosetting resin composition into a mold while a curing reaction of the resin composition is incomplete. The thermosetting resin composition is then cooled in the mold until becoming semi-cured and removed as a semi-cured product from the mold. The semi-cured product is separated from the unnecessary part and separately heated to progress a thermosetting reaction of the thermosetting resin composition. The unnecessary part may be used as a reworked raw material by regrinding the unnecessary part and mixing it with a fresh thermosetting resin composition. Then, a resultant mixture is used to perform a new injection molding.Type: GrantFiled: April 18, 2016Date of Patent: August 9, 2022Assignee: SOMAR CORPORATIONInventors: Hirohisa Ishizaki, Akira Ochiai

Patent number: 11365155Abstract: A moldable green-body composite includes milling silicon nitride powder with a solvent and adding a surface modifier to the milled slurry to modify a surface of the silicon nitride particles. A polysiloxane in a solvent and a binder are also added to create a green body slurry. The solvents may be polar or non-polar solvents. A sintering aid, such as yttria-alumina, may be added to the slurry as well. A reduced density silicon nitride ceramic is made from the moldable green-body composite by molding the moldable green-body composite in a mold and curing at a curing temperature to convert the moldable green-body composite to a converted composite. The converted composite can then be sintered to form a reduced density silicon nitride ceramic that has a smooth surface finish and requires no post machining or polishing. The reduced density silicon nitride ceramic may also have very good dielectric properties.Type: GrantFiled: April 5, 2021Date of Patent: June 21, 2022Assignee: ATC Materials IncInventor: Mark Hawthorne
