Publication number: 20240077091Abstract: A hydraulic pump performance deterioration detection system according to one embodiment includes: a variable displacement hydraulic pump that supplies a hydraulic liquid to a hydraulic actuator to move the hydraulic actuator; a regulator that changes a displacement of the hydraulic pump in accordance with a command current; and control circuitry that feeds the command current to the regulator. When the hydraulic actuator is not moving, in a state where a switching valve located on a passage through which the hydraulic liquid delivered from the hydraulic pump flows is switched to a closed position and the hydraulic pump is being driven at a predetermined rotation speed, the control circuitry determines whether or not performance of the hydraulic pump has deteriorated based on a current value of the command current and a delivery pressure of the hydraulic pump measured by a pressure sensor.Type: ApplicationFiled: September 1, 2023Publication date: March 7, 2024Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Akihiro KONDO, Yousuke KATAOKA, Jun UMEKAWA

Publication number: 20240077092Abstract: A hydraulic pump performance deterioration detection system according to one embodiment includes: a hydraulic pump that is driven by a prime mover and that supplies a hydraulic liquid to a hydraulic actuator to move the hydraulic actuator; a switching valve located on a passage through which the hydraulic liquid delivered from the hydraulic pump flows, the switching valve being switchable between an open position and a closed position; and control circuitry configured to change a rotation speed of the prime mover. When the hydraulic actuator is not moving, in a state where the switching valve is switched to the closed position, the control circuitry determines whether or not performance of the hydraulic pump has deteriorated based on the rotation speed of the prime mover and a delivery pressure of the hydraulic pump measured by a pressure sensor.Type: ApplicationFiled: September 5, 2023Publication date: March 7, 2024Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Akihiro KONDO, Yousuke KATAOKA, Jun UMEKAWA

Patent number: 11020783Abstract: A mold holder device in a press brake includes a mold clamp that clamps a mold with respect to a mold contacting surface provided for a holder body of the mold holder device. The mold clamp is pivotally arranged on the holder body. A long groove is formed in a mold clamping surface with which the mold clamp clamps the mold with respect to the mold contacting surface. The long groove is in parallel with a pivot axis of the mold clamp. A metal pipe member has a longitudinal slit and is inserted in a rotation restricted state into the long groove. A part of an outer peripheral surface of the pipe member is protruded toward the mold contacting surface.Type: GrantFiled: April 11, 2017Date of Patent: June 1, 2021Inventors: Yohei Fuchinoue, Seishiro Ikeda, Jun Kataoka

Patent number: 9939535Abstract: A Compton camera includes a scattering detection unit, an absorption detection unit, a signal processing unit, a first shield unit, and a second shield unit. The scattering detection unit detects Compton scattering of incident radiation emitted from a radiation source. The absorption detection unit detects absorption of incident radiation that has undergone Compton scattering at the scattering detection unit. The signal processing unit obtains an image of the radiation source based on coincident detection events of Compton scattering of radiation at the scattering detection unit and absorption of radiation at the absorption detection unit. The first and second shield units are provided between the scattering detection unit and the absorption detection unit. The first shield unit selectively allows forward-scattered radiation to pass and selectively blocks back-scattered radiation.Type: GrantFiled: September 26, 2014Date of Patent: April 10, 2018Assignees: WASEDA UNIVERSITY, HAMAMATSU PHOTONICS K.K.Inventors: Jun Kataoka, Toru Nishiyama, Shinji Ohsuka, Michito Hirayanagi, Shunsuke Adachi, Tetsuya Uchiyama
