Publication number: 20230008189Abstract: An air bag to be mounted in a cargo container for facilitating discharge of powder granular material from a liner filled with the powder granular material, the air bag including a synthetic resin film bag that assumes a triangle or trapezoid shape in a state where the bag has a flat form with no air injected. A gusset is formed in a base part of the triangle or in a lower base part of the trapezoid by folding the synthetic resin film inward. Flexible reinforcing covers having a triangle or trapezoid shape in accordance with the triangle or trapezoid shape of the bag are laminated respectively on one surface and the other surface of the bag. A short air outlet tube, as well as an air inlet tube, is connected to one side part of the triangle or one leg part of the trapezoid of the bag.Type: ApplicationFiled: November 6, 2020Publication date: January 12, 2023Inventors: Yuta SAITO, Kentaro HATA

Patent number: 4627239Abstract: A hydraulic circuit arrangement for controlling a plurality of actuators connected to a high pressure line of a main pump parallel to each other has a sequence valve interposed in a line bypassing from the high pressure line to a reservoir. In the bypass line a throttle is interposed between the sequence valve and the reservoir. A regulator for controlling the displacement of the main pump is connected to the bypass line between the sequence valve and the throttle at a pilot chamber thereof. An auxilially pump is connected to the high pressure line parallel with the sequence valve. A delivery line of the auxilially pump has a bypass line interposed with a relief valve. The main pump may be switched to unloaded condition for the stand-by condition of the actuators and to loaded condition for the operation condition of the actuators.Type: GrantFiled: January 28, 1985Date of Patent: December 9, 1986Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Hisaaki Nishimune, Yoshikuni Ichimura, Kentaro Hata
