Abstract: A printed circuit board includes: an insulating member; a first wiring layer disposed in the insulating member, and including first and second pattern layers spaced apart from each other based on a thickness direction of the printed circuit board; and a second wiring layer disposed in the insulating member, and spaced apart from the first pattern layer over the first pattern layer based on the thickness direction. Based on the thickness direction, an insulation distance between the first pattern layer and the second pattern layer is smaller than an insulation distance between the first pattern layer and the second wiring layer, and each of the first and second pattern layers is thinner than the second wiring layer.

Abstract: The present disclosure relates to an electronic device, and more specifically, to an electronic device including a printed circuit board including a heat-generating element arranged on one surface thereof, and a heat transfer coin provided such that one surface of the heat transfer coin comes into contact with a portion of the other surface of the printed circuit board, opposite to the heat-generating element, so as to dissipate heat generated from the heat-generating element. Accordingly, the present disclosure provides an advantage of improving heat dissipation performance without increasing the thickness of the printed circuit board.

Abstract: A communication apparatus is provided to include an apparatus enclosure that includes a substrate seating surface and at least one or more connection grooves formed on the substrate seating surface, a first printed circuit board disposed on the substrate seating surface, a second printed circuit board disposed on the substrate seating surface on one side of the first printed circuit board, and at least one or more connectors disposed within the connection groove and configured to electrically connect the first printed circuit board and the second printed circuit board.

Abstract: An artificial intelligence-based injection molding system in which molding conditions can be changed to manufacture fair-quality products when defective products are manufactured because of disturbances during the injection molding including an injection molding machine which performs injection molding by injecting a molding material into a mold; an injection state data acquisition unit for acquiring, during injection molding, current injection state data that includes the viscosity profile of the molding material injected into the mold and/or the injection pressure value thereof; a determination unit, which inputs the current injection state data into a molding quality maintenance model trained with predetermined target injection state data, so as to determine whether to maintain molding quality; and a molding condition setting unit for changing a preset molding condition so that the current injection state data follows the target injection state data, when the determination unit determines not to maintain t

Abstract: An artificial intelligence-based injection molding system comprising a standard data extraction unit for extracting target standard data of a product produced by a mold from mold information about the mold to which a molding material is supplied; a molding condition output unit inputing the extracted target standard data into a pre-learned molding condition generation model to output a molding condition; an injection molding device, supplying the molding material to the mold according to the molding condition to produce the product; and a determination unit, comparing production standard data of the produced product and the target standard data to determine whether the molding condition is appropriate, wherein, if the determination unit determines that the molding condition is inappropriate, the molding condition output unit generates the production standard data and the molding condition as one set of feedback data, and trains the molding condition generation model with the set of feedback data.

Abstract: An instant cosmetic preparation device includes: a housing; a finished product container transfer part which is configured to transfer to a finished product container filled with a cosmetic mixture stored inside the housing to a sealing position; a sealing part which is arranged inside the housing; and a control unit which is arranged inside the housing for controlling the operation of the sealing part to seal an open injection port of the finished product container.

Abstract: An instant cosmetic preparation device, including: a housing of a given shape; a finished product container transfer part which is configured to transfer to a finished product container filled with a cosmetic mixture stored inside the housing to a sealing position under the user's control; a sealing part which is arranged inside the housing for sealing the mouth of the finished product container; and a control unit which is arranged inside the housing for controlling the operation of the sealing part to seal the mouth of the finished product container.

Abstract: A method of effectively extracting metal ions by sonication from red med that is waste remaining after extracting aluminum from bauxite. The method includes: (a) introducing, into a reactor placed in a constant-temperature tank, (1) a neutralized red mud slurry and an acidic solution or (2) red mud slurry, distilled water and an acidic solution, to form a red mud slurry, and heating the constant-temperature tank to allow the red mud slurry to react while sonicating the red mud slurry, thereby extracting metal ions from the red mud; and (b) filtering a product resulting from step (a) to provide a filtrate and a red mud residue, and separating and recovering the filtrate and the red mud residue, wherein the sonication in step (a) is performed using an ultrasonic generator by applying ultrasonic waves to an ultrasonic tip placed in the constant-temperature tank.

Abstract: A method and apparatus of controlling an uplink transmit power are provided. A maximum power reduction (MPR) is determined based on resource allocation. The resource allocation comprises a number of contiguous resource blocks in a channel bandwidth which is divided into a first region, a second region and a third region. The MPR is determined according to the number of the contiguous resource blocks in the first region and the third region, and the MPR is determined according to the starting index in the second region. The MPR in the third region increases as the number of the contiguous resource blocks decreases.
