  • Publication number: 20250179599
    Abstract: It is provided a mechanical structural part and a method of manufacturing the same. The mechanical structural part comprises a chemical composition containing C: 0.45% to 0.51%, Si: 0.15% to 0.35%, Mn: 0.60% to 0.90%, P: 0.030% or less, S: 0.025% or less, Al: 0.040% to 0.059%, Cr: 0.10% to 0.50%, and N: 0.0060% to 0.0100%, with the balance being Fe and inevitable impurities, and a hardened layer by induction hardening and tempering treatment, wherein an area ratio of crystal grains each having a prior austenite grain size of 80 ?m or less in the hardened layer is 80% or more, and a number ratio of grains each having a grain size twice or more than a mode of grain size in the hardened layer is 5% or less.

  • Publication number: 20250133660
    Abstract: A restricting device for a flexible wiring board includes an insertion portion into which at least both side portions of the flexible wiring board are inserted. The insertion portion includes: a rear restricting portions protruding in a thickness direction of the flexible wiring board; a front restricting portion located forward of the rear restricting portion in an insertion direction; a restricting region formed between the front restricting portion and the rear restricting portion, and an inner restricting portion located further inward than the rear restricting portion with respect to a width direction of the flexible wiring board and protruding in a direction opposite to a protruding direction of the rear restricting portion. The protruding portion passes over the rear restricting portion and is restricted from moving in a front-rear direction in the restricting region while the flexible wiring board is being inserted into the insertion portion.

  • Patent number: 11898372
    Abstract: An operating device includes a lock mechanism unit that regulates relative movement of an operating unit with respect to a supporting member, and a controller that releases locking of the lock mechanism unit when input of an operator is detected by an operation detector. When contact of a finger with a surface panel is detected by a first detection member, locking of the operating unit by the lock mechanism unit is released. In addition, when a pressing operation to the operating unit is detected by a second detection member, control is performed so that a response force providing mechanism operates.

  • Publication number: 20220254141
    Abstract: An image processing device includes a search scenario acquisition unit and a search unit. The search scenario acquisition unit acquires a search scenario in which one or more search processes of searching for an image using an image feature based on a target image, which is an image of a search target, in a search condition are combined. The search unit searches for a matching image, which is an image to be searched, using a combination of the search processes represented by the search scenario and outputs search result information representing an area in the matching image detected through the search.
