Patent number: 10611166Abstract: A processor of a print device performs empty processing in a case where it has determined that it has received, from a remaining ink amount detector, a first signal that indicates that a remaining amount of an ink is not greater than a first prescribed amount. The processor also performs the empty processing in a case where it has not determined that it has received the first signal, but has determined that it has received a second signal. In the empty processing, the processor performs soak cleaning of a nozzle face and stores an empty soak standby flag in an EEPROM. The empty soak standby flag is a flag that prohibits the performing of a printing operation. Therefore, the print device is able to reduce the possibility that a decline in print quality will occur.Type: GrantFiled: August 9, 2019Date of Patent: April 7, 2020Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Katsunori Nishida, Yoshinori Kato

Patent number: 10155282Abstract: In a friction stir welding method, a pair of plate materials is arranged opposing one another such that the ends thereof are butted together, after which friction stir welding is performed. A first shoulder is arranged at one surface of the pair of plate materials and a second shoulder is arranged at the other surface of the plate materials to sandwich therebetween a joint to be formed by friction stirring of the end parts of the plate materials, and the first shoulder and the second shoulder are rotated, thereby friction stirring the joint of the pair of plate materials. As the joint is friction stirred, the first shoulder and the second shoulder are moved from the other surface toward the one surface of the plate materials, thereby forming at the joint a protruding part protruding from the one surface of the plate materials as the friction stir welding is performed.Type: GrantFiled: July 15, 2014Date of Patent: December 18, 2018Assignee: MITSUBISHI HEAVY INDUSTRIES ENGINEERING, LTD.Inventor: Yoshinori Kato
