  • Patent number: 11953047
    Abstract: A formed body of Cu—Al—Mn-based shape-memory alloy may include a screw portion, wherein the screw portion is a form-rolled portion. A method for producing a formed body of Cu—Al—Mn-based shape-memory alloy may involve forming a screw portion having superelasticity by plastically working at least a portion of a material for the formed body with form-rolling in a state that a crystal structure is an A2-type structure and then, subjecting heat-treatment so as to convert the A2-type crystal structure into an L21-type crystal structure. The screw portion can be formed with good working property, and has excellent fatigue resistance and breaking resistance.

  • Patent number: 11818118
    Abstract: An image forming apparatus includes a communication interface, a processor, and a memory. The communication interface communicates with an external service including an authorization code flow. The memory stores a front-end application having a UI and a back-end application having no UI and registered in the external service, which are programs executed by the processor. The processor causes the external service to execute the authorization code flow based on the information of the back-end application in response to a request from the front-end application, receives an authorization code from the external service, causes the front-end application to redirect using a URL previously associated with the back-end application on the external service, and acquires an access token from the external service by the back-end application using the authorization code.

  • Patent number: 11260159
    Abstract: A percutaneous catheter provides an adjustable diameter in order to reduce pressure loss, maintain a required flow, and avoid increasing a load to the patient. A catheter tube is formed of braided wires in an intersecting manner and extends in an axial direction. A distal tip is affixed to a distal side of the catheter tube and is configured to engaged a distal end of a dilator. The catheter tube includes a non-coated portion on a proximal side of the distal tip and a coated portion embedded in a resin material. An inner diameter of the non-coated portion is larger than an outer diameter of the dilator. When the dilator is fully inserted through the percutaneous catheter, the non-coated portion expands in the axial direction, reducing its in inner diameter so that an inner surface of the non-coated portion comes into tight contact with an outer surface of the dilator.
