  • Publication number: 20030196672
    Abstract: A liquid container includes a receptacle for storing a liquid content such as mascara, a squeezer fitted in the mouth of the neck of the receptacle, and an applying shaft of a cap inserted into the receptacle through the squeezer. The squeezer is made of a material having flexibility and formed in such an approximate cylindrical shape that the diameter of the squeezer becomes gradually smaller from the top end toward the lower part and becomes gradually greater from that lower part to the bottommost part while a multiple number of vertical slits are cut out in the peripheral wall of the squeezer. The squeezer becomes gradually wider from the lower part to the bottommost part, so as to avoid collision with the applying part of the applying shaft that holds the liquid content.

  • Patent number: 6616262
    Abstract: A method of controlling an image processing condition comprises: a first step of inputting a first test image on a recording sheet, and performing first calibration that determines an image processing condition based on a density of the first test image; a second step of automatically forming a second test image, measuring a density thereof, and performing second calibration that determines the image processing condition based on the measured density, a third step of receiving the image processing condition, calibrating the received condition and an engine characteristic at first calibration time, and storing a calibrated result, and a fourth step of correcting, at the second calibration and the image processing condition storage, the stored condition based on the calibrated and stored engine characteristic and the measured engine characteristic. Thus, a printing characteristic can be stabilized as a user's load is reduced by combining plural calibrations.

  • Publication number: 20030160986
    Abstract: Disclosed are a printer correcting apparatus and method of controlling the same for making it possible to more easily perform calibration for the purpose of providing a printer with stabilized printing characteristics. A server apparatus (1) is connected via a network (5) to a color printer (2) to be corrected. A scanner (3) connected to the server apparatus (1) is used to input a printer chart (61), which serves as color printing information classified by density relating to each color component, which is used in color printing, output by the printer (2). The server apparatus (1) executes calibration of the operation-start command signal (3) and calibrates the printer (2) utilizing the printer chart (61) that has been input using the corrected scanner (3).
