  • Patent number: 11975379
    Abstract: A hot press forming die includes a die main body (2) made of alloy tool steel, and a number of forming projections (3) projecting on the die main body and configured to form a forming surface (5) that comes into contact with a heated metal plate material that is an object to be formed and form a refrigerant passage through which a cooling medium flows. The die main body includes a first forming portion (14) in which the forming surface is formed to extend in a direction intersecting a forming direction of the metal plate material, a second forming portion (15) in which the forming surface is formed to extend in the forming direction, and a third forming portion (16) configured to connect the first forming portion and the second forming portion such that the forming surface becomes a convex surface. The forming projection provided on the third forming portion is formed to be a projecting strip extending between the first forming portion and the second forming portion.

  • Patent number: 11555870
    Abstract: A magnetic sensor device includes a magnetic sensor detecting a detection-target magnetic field, and a soft magnetic structure near the sensor. In an orthogonal coordinate system having two orthogonal axes for representing an applied field strength and a magnetization-corresponding value, coordinates representing the applied field strength and the magnetization-corresponding value move along a minor loop not in contact with a major loop as the strength of an external magnetic field including the detection-target magnetic field varies within a variable range, where the applied field strength is a strength of a magnetic field applied to the soft magnetic structure, the magnetization-corresponding value is a value corresponding to magnetization of the soft magnetic structure, and the major loop is, among loops traced by a path of the coordinates as the applied field strength is varied, a loop that is the largest in terms of area of the region enclosed by the loop.
