Abstract: A toothpaste filled in a container which has two chambers and is capable of simultaneously discharging two different compositions filled respectively in the two chambers when the main body of the container is pressed, wherein a ratio of a storage modulus GA? of Composition (A) filled in one chamber to a storage modulus GB? of Composition (B) filled in the other chamber falls within a range of from 0.6 to 1.4. By controlling the ratio, it is possible to stably discharge from the container storing these two compositions separately predetermined amounts of these two compositions which will otherwise cause a time-dependent change if they are pre-mixed thereby failing to attain the purpose of their addition.

Abstract: A toothpaste filled in a container which has two chambers and is capable of simultaneously discharging two different compositions filled respectively in the two chambers when the main body of the container is pressed, wherein a ratio of a storage modulus GA′ of Composition (A) filled in one chamber to a storage modulus GB′ of Composition (B) filled in the other chamber falls within a range of from 0.6 to 1.4. By controlling the ratio, it is possible to stably discharge from the container storing these two compositions separately predetermined amounts of these two compositions which will otherwise cause a time-dependent change if they are pre-mixed thereby failing to attain the purpose of their addition.

Abstract: An apparatus for loading a planar subject at a predetermined position has holding means operative to hold one one of the planar subject at a predetermined level, and regulating means for detecting the thickness of the planar subject from the amount of operation of the holding means and regulating the level of the other end of the planar subject. This loading apparatus is suitably used in a pattern depicting apparatus.

Abstract: In a pattern generating system for scanning a pattern on a surface of a workpiece with a laser beam modulated by drawing data so as to form a pattern corresponding to design pattern data, a plurality of through holes are formed at predetermined positions of the workpiece. Beams transmitted through the through holes are directed to a sensor for generating a detection output representing positions of the transmitted beams. A computer generates position data of the through holes on the basis of the detection output and calculates a positional error and a deformation amount of the workpiece. A correcting device corrects the drawing on the basis of the positional error and the deformation amount.
