  • Patent number: 12006117
    Abstract: Provided is a container including a container portion configured to form a storage space in which contents are stored, a head portion disposed at an upper side of the container portion and configured to promote discharge of the contents, which enter the head portion from the container portion, through an internal pressure change caused by a pressing portion which is formed at one side of the head portion and made of an elastic material, and a nozzle configured to discharge the contents, which enter the nozzle from the head portion, in fixed amounts.

  • Publication number: 20240141481
    Abstract: A method of cleaning a semiconductor processing system may include applying a vacuum pressure to a supply pipeline through which a process fluid is transferred to a process chamber and purging the supply pipeline with a cleaning gas, wherein the purging the supply pipeline with the cleaning gas includes by supplying the cleaning gas to a front end of the supply pipeline and discharging the cleaning gas supplied to the supply pipeline by applying an atmospheric pressure from a back end of the supply pipeline.

  • Patent number: 11949881
    Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

  • Patent number: 10405814
    Abstract: An X-ray imaging apparatus according to an embodiment of the present invention includes an X-ray generator that irradiates an object with X-rays during an exposure period; an X-ray detector that detects X-rays transmitted through the object; and a movement unit that moves the X-ray generator and the X-ray detector, wherein the X-ray generator is moved along an arc having a radius of curvature within a range with respect to a rotational axis, wherein the motion along the arc starts at a first time point and ends at a second time point, wherein the X-ray detector is moved in a linear direction having an angle with respect to a plane of the arc during at least a partial period of a period between the first time point and the second time point, wherein the motion in a linear direction starts at a third time point that is the same as or later than the first time point and ends at a fourth time point that is the same as or earlier than the second time point, and a first difference between the first time point and t
