Publication number: 20230049222Abstract: A magnetic linear position detector includes a stator and a mover that is movable along a first direction with respect to the stator. One of the stator and the mover is provided with a magnetic detector. The other of the stator and the mover is provided with a magnet having a first face facing the magnetic detector. The first face is magnetized in such a manner that a magnetization direction changes in an arc shape around a magnetization center point. The magnetic detector is an element whose output changes depending on a direction of a magnetic field.Type: ApplicationFiled: March 10, 2020Publication date: February 16, 2023Applicant: Mitsubishi Electric CorporationInventors: Makoto HIGASHINO, Takeshi MUSHA, Yoshinao TATEI, Hisanori TORII

Patent number: 6304794Abstract: When a molten plastic is molded using a metal mold, sufficient cooling time has to elapse before the metal mold is opened, but this cooling time restricts the production per unit time. If a metal mold is opened without sufficient cooling, the plastic undergoes significant deformation by thermal shrink. If this deformation can be estimated and the metal mold designed so as to make allowance for the anticipated deformation, it will be possible to produce a molding with a shape that is equal to the design dimensions, despite shortening the cooling time. The finite element method is used to obtain the deformation. Mold design can also be performed taking account of the deformation due to the hydrostatic pressure that is produced when the molding is filled with its liquid contents. In addition, as for a portion of an in-mold labelled container which include lamination construction, the deformation due to thermal shrink is not estimated as a container which an in-mold label is not being applied.Type: GrantFiled: December 10, 1997Date of Patent: October 16, 2001Inventors: Naohide Nishimine, Hisanori Torii, Nobunori Oji, Keiichiro Sugai, Yuko Tamiya
