  • Patent number: 11933640
    Abstract: 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 includes a magnetic detector, and the other of the stator and the mover includes a magnet. The magnet has a first face facing the magnetic detector, and the first face is provided alternately with N poles and S poles along the first direction. The magnet includes a first region and a second region provided on each side of the first region along the first direction. In the first region, a length along a second direction perpendicular to the first face is constant. In the second region, a length along the second direction is different from the length in the first region.

  • Publication number: 20230068474
    Abstract: The present disclosure includes: a magnetic member configured to cause a large Barkhausen effect; a power generation coil disposed so as to be wound around the magnetic member; and soft magnetic members formed at both end portions of the magnetic member so as to be in contact with the magnetic member and so as to press the magnetic member. Consequently, evenness of a magnetic flux density inside the magnetic member is increased, and the large Barkhausen effect is stably caused, whereby a highly stable power generation element is obtained.

  • Publication number: 20230049222
    Abstract: 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.

  • Patent number: 11221231
    Abstract: An encoder includes a magnetic sensor having higher detection sensitivity to a magnetic field applied in a reading direction, while having lower detection sensitivity to a magnetic field applied in a direction forming a greater angle with respect to the reading direction, an encoder substrate having the magnetic sensor mounted thereon, a magnetic shield to shield against a magnetic field including a side portion covering sides of the magnetic sensor and a top-side portion covering a top of the magnetic sensor, a permanent magnet located to face the encoder substrate, a shaft having the permanent magnet attached to a tip end of the shaft, and a bracket to support the shaft in a rotatable manner, wherein on the side portion of the magnetic shield, a notch as a connector insertion portion is located not to overlap an extended area of the magnetic sensor in the reading direction.

  • Patent number: 6304794
    Abstract: 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.
