  • Publication number: 20180148828
    Abstract: In an apparatus for quantifying the amount of evaporation deposition of a solid substance and its method, the apparatus is connected to a reaction chamber, and a solid substance to be evaporated, a heating source and a load cell are disposed in a heating chamber. The load cell is for detecting the weight of the solid substance, and the reduced weight of the solid substance to be evaporated per unit time is equal to the mass flow of the reaction gas, so that the status of the reaction gas can be known by the weight simultaneously. When the solid substance is heated to a state to form the reaction gas, the heating chamber reaches a saturated vapor pressure greater than a vacuum background pressure of the reaction chamber, the reaction gas continues to flow along the pipeline stably towards the reaction chamber to manufacture a thin film.

  • Patent number: 8568652
    Abstract: A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations.

  • Publication number: 20120138771
    Abstract: A reflective optical detecting device is for detecting movement of an object in a predetermined area. The reflective optical detecting device includes a light emitting unit, at least two optical detectors, and a comparing unit. The light emitting unit is used for illuminating the predetermined area. The optical detectors are disposed at opposite sides of the light emitting unit, and each of the optical detectors is associated with a respective detection region within the predetermined area for generating an output signal in response to light reflected from the object and detected thereby. The comparing unit is coupled to the optical detectors for receiving the output signal from each of the optical detectors, and is operable to output a comparison result according to the output signal of each of the optical detectors. The comparison result is to be used for determining the movement of the object.

  • Patent number: 7879133
    Abstract: A method has steps of providing a three-dimensional (3-D) laser scanner, providing a computer, obtaining point group data (PGD) and calculating measuring an outline of a top reactant stratum from the PGD. The step of providing a 3-D laser scanner directs a 3-D laser scanner at reactant strata in a blast furnace and output PGD that represent digital data of an inside of the blast furnace. The step of providing a computer connects the 3-D laser scanner to a computer having a point group analysis program. The step of calculating an outline of the top reactant stratum from the PGD is performed by the point group analysis program to calculate an outline of the top reactant stratum in the blast furnace from the PGD. At least one two-dimensional laser scanner is used to measure a path of the reactant being charged.
