  • 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.

  • Publication number: 20220380183
    Abstract: A control unit performs a travel stop process for stopping travel of a travel unit in response to an indicator detection unit detecting a stop notice indicator section and then detecting a stop position indicator section. After the travel of the travel unit is stopped as a result of the travel stop process, the control unit performs a transfer process for causing a transfer unit to transfer an article. The control unit performs, instead of the transfer process, anomaly notification processing for providing a notification of an occurrence of an anomaly to a superordinate control unit, after the travel of the travel unit is stopped by the travel stop process, in response to: (i) a travel distance, from a position at which the indicator detection unit has detected the stop notice indicator section, being smaller than a determination distance smaller than a notice distance, and (ii) the indicator detection unit detecting the stop position indicator section.
