  • Patent number: 12218039
    Abstract: A semiconductor package may include a redistribution substrate having a first surface and a second surface, opposite to each other, a semiconductor chip on the first surface of the redistribution substrate, and a solder pattern on the second surface of the redistribution substrate. The redistribution substrate may include an under-bump pattern coupled to the solder pattern, a first redistribution pattern on the under-bump pattern, the first redistribution pattern including a first via portion and a first wire portion, and a first seed pattern between the under-bump pattern and the first redistribution pattern and on a side surface of the first via portion and a bottom surface of the first wire portion. A bottom surface of the first seed pattern may be at a level lower than a top surface of the under-bump pattern.

  • Publication number: 20250020399
    Abstract: A blow-down method is applied to a reliquefaction system in which boil-off is compressed by a compressor, cooled and reliquefied through a heat exchanger, and returned to the tank after passing through a gas-liquid separator. The reliquefaction system includes a pressure compensation line extending from a downstream side of the compressor to an upside of the gas-liquid separator without passing through the heat exchanger; and a nitrogen blanket line along which nitrogen is supplied to the pressure compensation line. In the event of a trip of the reliquefaction system, nitrogen is supplied to the pressure compensation line along the nitrogen blanket line and is delivered to the downstream side of the compressor to pass through the heat exchanger along the reliquefaction line such that the heat exchanger and the reliquefaction line are blown down to remove compressed gas and reliquefied gas therefrom while being subjected to nitrogen (N2) purging.

  • Patent number: 8556360
    Abstract: A textile printing method applying inkjet printer comprises the steps for feeding a fabric by a fabric feed roller, applying a pretreatment liquid to the fabric by jetting the pretreatment liquid installed in a pretreatment liquid reservoir installed respective containers filled with individual compositions of a pretreatment liquid, so that such individual compositions are concurrently mixed and applied on the fabric surface to pretreat the fabric by operation of a control unit depending upon the fabric material through a pretreatment head, drying the pretreatment liquid applied to the fabric through a drier, and printing on the dried fabric by jetting the ink installed in a ink reservoir through the printing head. The pretreatment head, the drier and the printing head are serially arranged so that the steps for applying a pretreatment liquid, drying the pretreatment liquid and printing on the dried fabric are concurrently performed.
