Publication number: 20230391092Abstract: A liquid ejecting apparatus includes a liquid ejection head, a supply tank, a recovery tank, a supply flow path, a recovery flow path, a pressurizing mechanism pressurizing the inside of the supply tank, and a depressurizing mechanism depressurizing the inside of the recovery tank. A filling period, in which a filling process is performed to fill, with the liquid, a nozzle, the supply flow path, and the recovery flow path, includes a period that is after a meniscus is formed in the nozzle and before the liquid reaches the recovery flow path. In the period, the pressurizing and the depressurizing mechanisms are driven; and in the period, Pt_out>?|Pm| is satisfied, where Pm indicates a pressure at which the meniscus is broken and Pt_out indicates a pressure in the recovery tank.Type: ApplicationFiled: June 2, 2023Publication date: December 7, 2023Inventors: Yu HASEGAWA, Eiichiro WATANABE, Masami OTA, Hiroaki OKUI

Publication number: 20050081273Abstract: The present invention concerns a hand protection strap (1), having a flexible, substantially planar body (2) whose upper side forms a support surface for the palm and fingers of a user's hand. An attachment device (3, 4) is provided at one end region of the body (2) in order to attach the hand protection strap (1) to the user's wrist and/or forearm. Finger retention elements (5) are provided at the lower end region of the body (2) in order to retain the hand protection strap (1) on at least two fingers. A projection (6) is provided on the finger region of the support surface, in order to afford better grip and security to the fingers in particular in the region of the proximal finger joint. The planar body (2) is equipped, at least in the palm region of the support surface, with at least one reinforcing layer (7).Type: ApplicationFiled: August 18, 2004Publication date: April 21, 2005Inventor: Masami Ota
