Patent number: 11796553Abstract: A chemical dispensing mechanism detects the liquid surface of a chemical including a chemical container mounted on a chemical disk. A calculation control unit controls the operation of the chemical dispensing mechanism. The calculation control unit performs a first raising operation, in which a chemical stored in the chemical container is suctioned by the chemical dispensing mechanism, which is then raised up to a first bubble detection position, determines whether a liquid surface is present, and outputs an alert indicating the presence of a bubble on the liquid surface when the liquid surface has been determined to be absent. The first bubble detection position is when the tip of a dispensing nozzle of the chemical dispensing mechanism remains inside the liquid when there are no bubbles present on the liquid surface, and is exposed from the inside of the liquid when there are bubbles present on the liquid surface.Type: GrantFiled: June 27, 2019Date of Patent: October 24, 2023Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Nobuhiko Sasaki, Takanori Sawada, Toshiyuki Shimamori, Chie Yabutani
