Patent number: 11970003Abstract: Provided is a liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus capable of inhibiting contamination of a liquid after being ejected. The liquid ejection apparatus has an ejection unit having an ejection part and an ejection energy generation element that ejects a liquid from the ejection part by using a principle of inkjet ejection into an internal space in a storage part capable of storing the ejected liquid. When ejecting the liquid, the ejection unit covers an opening portion of the storage part to thereby screen the internal space in the storage part from an external space.Type: GrantFiled: March 14, 2022Date of Patent: April 30, 2024Assignee: Canon Kabushiki KaishaInventors: Futoshi Hirose, Shinichi Sakurada, Sachiko Yamauchi, Tatsuaki Orihara, Yoshinori Itoh, Nobuyuki Kuwabara, Tsutomu Shiratori

Publication number: 20230315064Abstract: A slave station (102), in an initial state, puts a relay device to a relay-disconnected status and transmits an assignment request requesting address assignment for the own slave station. A master station (101), in response to an assignment request from an adjacent slave station (102), performs address assignment for the slave station (102), and transmits an assignment request response containing an assigned address. The slave station (102), upon reception of the assignment request response, stores the address contained in the assignment request response to a memory, and puts the relay device to a relay status. If the slave station (102) receives the assignment request after address assignment for the slave station is completed, the slave station performs address assignment for a slave station being a sender of the assignment request instead of relaying the assignment request, and transmits an assignment request response containing an assigned address.Type: ApplicationFiled: June 8, 2023Publication date: October 5, 2023Applicant: Mitsubishi Electric CorporationInventors: Futoshi HIROSE, Daisuke OSAGAWA
