  • Publication number: 20250353407
    Abstract: A slide device includes a rail and a slider. The rail is provided with multiple locking holes arranged in an extension direction of the rail. The slide lock device includes a casing joined to the slider, at least one lock member supported by the casing to be rotatable between a release position and a lock position, an urging member urging the lock member toward the lock position, and an operating member displaceably supported by the casing and contacting the lock member. The lock member includes at least one convex part configured to be engaged with the locking holes when the lock member is in the lock position and to be disengaged from the locking holes when the lock member is in the release position. When the operating member is moved from an initial position to a post-operation position, the operating member presses the lock member and moves the lock member from the lock position to the release position.

  • Patent number: 12351930
    Abstract: Electroplating apparatus includes an electroplating tank that stores an electrolyte solution in which at least objects to be electroplated and magnetic media sink, and at least one magnetic rotator rotatably arranged under the electroplating tank so as to generate an alternating magnetic field. The magnetic rotator is arranged to section an internal space of the electroplating tank into a first space occupying a space above the magnetic rotator and a second space occupying a remaining space other than the first space. The magnetic rotator is arranged to be movable in a lateral direction intersecting a rotational axis of the magnetic rotator, allowing the objects to be shifted between a condition of being present in the electrolyte solution and in the first space and a condition of being present in the electrolyte solution and in the second space.

  • Publication number: 20250033544
    Abstract: [TASK] In a reclining seat device, the behavior of the vehicle is accurately conveyed to a seated occupant without regard to the reclining angle of the seat back with respect to the seat cushion. [SOLUTION] The air cells 30 of the seat cushion 22 are vibrated with a higher intensity than those of the seat back 26 when the reclining angle is smaller than a predetermined value, and the air cells 30 of the seat back 26 are vibrated with a higher intensity than those of the seat cushion 22 when the reclining angle is equal to or greater than the predetermined value.

  • Patent number: 11236431
    Abstract: A method includes: agitating base members that has been immersed in an electrolytic solution inside of an electroplating tank so as to flow in a circumference direction along an inner wall of the electroplating tank; and electroplating the base members flowing along the circumference direction in the electrolytic solution inside of the electroplating tank. The flow of the base members along the circumference direction is caused by a flow of magnetic media along the circumference direction in the electrolytic solution inside of the electroplating tank or is caused by rotation of an agitation unit provided at a bottom side of the electroplating tank. At least one of the base members touches a bottom cathode, and a base member positioned upward relative to the base member touching the bottom cathode is electrically connected to the bottom cathode via at least the base member touching the bottom cathode.

  • Patent number: 11072866
    Abstract: An electroplated article includes a base member that includes one or more base member-metallic elements; and an electroplated layer that is formed directly on the base member. The electroplated layer includes at least a first electroplated layer-metallic element and a second electroplated layer-metallic element that is different from the first electroplated layer-metallic element. The second electroplated layer-metallic element is a metallic element that is identical to at least one of the one or more base member-metallic elements. A ratio of the second electroplated layer-metallic element in the electroplated layer is continuously decreased as being away from the base member in the thickness direction of the electroplated layer. Alloy grains including at least the first and second electroplated layer-metallic elements are distributed in the electroplated layer such that a clear interface is not formed between the base member and the electroplated layer.

  • Patent number: 9695112
    Abstract: Objects of the present invention are to provide an industrially applicable method for producing an optically active ?-amino acid in high yield and in a highly enantioselective manner, to provide a simple production method of an optically active ?,?-disubstituted ?-amino acid, and to provide an intermediate useful for the above production methods of an optically active ?-amino acid and an optically active ?,?-disubstituted ?-amino acid. The present invention provides a production method of an optically active ?-amino acid or a salt thereof, the production method comprising introducing a substituent into the ? carbon in the ?-amino acid moiety of a metal complex represented by the following Formula (1): by an alkylation reaction, an aldol reaction, the Michael reaction, or the Mannich reaction, and releasing an optically pure ?-amino acid enantiomer or a salt thereof by acid decomposition of the metal complex.
