  • Patent number: 12264389
    Abstract: An Fe-based amorphous alloy ribbon reduced in iron loss, less deformed, and highly productive in a condition of a magnetic flux density of 1.45 T is provided. One aspect of the present disclosure provides an Fe-based amorphous alloy ribbon having first and second surfaces, and is provided with continuous linear laser irradiation marks on at least the first surface. Each linear laser irradiation mark is formed along a direction orthogonal to a casting direction of the Fe-based amorphous alloy ribbon, and has unevenness on its surface. When the unevenness is evaluated in the casting direction, a height difference HL×width WA calculated from the height difference HL between a highest point and a lowest point in a thickness direction of the Fe-based amorphous alloy ribbon and the width WA which is a length of the linear irradiation mark on the first surface is 6.0 to 180 ?m2.

  • Publication number: 20230398301
    Abstract: The present invention is characterized by including: a first member having a large diameter part and a small diameter part; a second member configured to be connected to the first member; and an element disposed between the first member and the second member, the first member having a recess on an end surface, the recess having a bottom that reaches a boundary position between the large diameter part and the small diameter part or a certain position on the side of the second member relative to the boundary position, the second member having a projection that is configured to fit into the recess with the element disposed between the recess and the projection, and having a screw hole extending to an inside of the projection to allow a screw part of the plunger to be screwed thereinto.

  • Patent number: 7404814
    Abstract: An infusion vessel has a vessel body having an internal cavity to serve as an infusion medium space, a cylindrical discharge mouth continuing from a lower portion of the vessel body, a medicine chamber disposed in the discharge mouth and kept airtight against ambient air, and a separator intervening between the infusion medium space and the medicine chamber so as to keep the space in a liquid-tight state against the holder. The separator is subject to displacement, rotation or deformation such as to bring the infusion medium space into communication with the medicine chamber, so that the infusion vessel can be made ready for use by conducting a simple operation to mix the medicine with the infusion medium that have been separated from each other within the vessel during its normal state before use.

  • Publication number: 20040016292
    Abstract: In a failure diagnosis apparatus of a position control system (variable valve operating system) wherein a target position of a control object (camshaft) changes and an actual position of the control object is feedback-controlled to the target position. A failure of the position control system is detected based upon a difference (&Sgr;C=&Sgr;A−&rgr;B) or a ratio (&Sgr;B/&Sgr;A) between an integral value &Sgr;A of the target position and an integral value &Sgr;B of the actual position thereof.
