  • Publication number: 20040244506
    Abstract: In an automatic metal solution dilutor according to the present invention, a densitometer (absorptiometer) measures absorbance of a diluted solution in a metering hopper. An electronic balance meters the diluted solution in the metering hopper so that a dilution magnification obtained from the absorbance reaches a prescribed value. A control part monitors the value measured by the densitometer and the value metered by the electronic balance for operating and controlling the quantity of a stock solution/diluent liquid fed to the metering hopper so that the dilution magnification reaches the prescribed value on the basis of the absorbance measured by the densitometer. Thus obtained is an automatic metal solution dilutor capable of diluting a concentrated liquid of the order of percentage to a metal solution of the order of ppm having a required quantity and a required concentration and correctly feeding the same to a feeder while performing in-line concentration control.

  • Patent number: 6086734
    Abstract: A thin-film depositing apparatus of the present invention deposits a sputtered film on a substrate in a sputtering chamber, and removes the substrate having the sputtered film deposited thereon from the sputtering chamber via a load-lock chamber by a robot arm. As a system for controlling the sheet resistance of the sputtered film deposited on the substrate, a measuring device using an eddy current method is mounted in the proximity of a substrate outlet of the load-lock chamber and measures the sheet resistance of the sputtered film of the substrate removed from the substrate outlet. With this structure, it is possible to provide a thin-film depositing apparatus which stably measures the sheet resistance of a thin film deposited on a substrate and performs feedback of the measurement result to control the film deposition conditions so that a thin film to be deposited on a subsequent substrate has a desired thickness.

  • Patent number: 5731860
    Abstract: A method of manufacturing a liquid crystal panel includes the steps of adjusting mutual positions of a pair of substrates, applying a pressure onto a sealing material made of a ultraviolet-curing resin applied onto the substrates, and hardening a predetermined temporal combining area of the sealing material by emitting a UV ray to be incident thereon. The resulting temporary fixed substrate is placed on a stage of a final hardening press device, and an embossed sheet having fine protrusions and recessions uniformly formed on a surface thereof is lowered to be superimposed onto the temporary fixed substrate. Further, by applying a vacuum suction to a sealed space between the stage and the embossed sheet, the entire surface of the temporary fixed substrate is pressurized under an atmospheric pressure to form a uniform cell gap as desired. Thereafter, a UV ray is applied by a UV lamp to finally harden the sealing material.
