A method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve. The method includes creating a user data set through multi-dimension analysis to define a user target base. A sealing member is attached to the dust storage container, the sealing member being provided in the dust storage container and between the opening and a storage space in which the dust is stored, for sealing a space between an inner wall surface of the dust storage container and the brush mechanism. The liquid crystal display device also comprises a compensation pattern formed at another predetermined portion on the first line where the protrusion is not formed, and having a lower height than the protrusion, a second column spacer corresponding to the compensation pattern. A second estimation is made of the user activity statistic based on the location information.
