Patent number: 11649611Abstract: A hydraulic system according to one aspect of the present disclosure includes: control valves interposed between a main pump and hydraulic actuators; and solenoid proportional valves connected to pilot ports of the control valves. Among the solenoid proportional valves, a first solenoid proportional valve and a second solenoid proportional valve are connected to a pair of pilot ports of a particular control valve, respectively. The first solenoid proportional valve and the second solenoid proportional valve are directly connected to an auxiliary pump. The solenoid proportional valves except the first solenoid proportional valve and the second solenoid proportional valve are connected to the auxiliary pump via a switching valve. The switching valve includes a pilot port that is connected, by a switching pilot line, to a first pilot line between the first solenoid proportional valve and the particular control valve.Type: GrantFiled: July 31, 2020Date of Patent: May 16, 2023Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Akihiro Kondo, Naoki Hata, Hitoshi Nakagawa

Publication number: 20160336826Abstract: Conductor segments that form a coil in a stator are formed by rectangular wires and are disposed in slots such that wide first faces are parallel to the radial direction. A plurality of conductor segments are disposed in the slots so that narrow second faces are opposite each other. The conductor segment disposed at the i-th (where i is an integer greater than or equal to 1) position from the inside of a stator core is joined to the conductor segment disposed in the (i+1)-th position in another slot such that vertical parts and horizontal parts thereof are opposite each other. The joined opposing first faces are formed parallel to the radial direction and are provided on both a first protrusion side and a second protrusion side.Type: ApplicationFiled: March 25, 2015Publication date: November 17, 2016Inventors: Kouhei ICHIKAWA, Hitoshi NAKAGAWA, Shinya KANOU, Mutsuo KOGA, Akira MINAMIURA

Patent number: 9258636Abstract: In a conventional headphone set, there is a possibility that a headband cannot be put in a suitable position when an ear pad is snugly mounted on an ear. A headphone set of this disclosure includes speaker units which output a sound. The headphone set also includes: speaker housings which are brought into contact with a user; connecting portions which are connected to the speaker housings in a state where the speaker housings are movable in a forward and rearward direction of the user; and a headband which has connecting portions on end portions thereof and is mounted on a head of the user in directions toward a crown of the head of the user. Due to such a constitution, the headphone set can be used in a more stable manner.Type: GrantFiled: March 11, 2015Date of Patent: February 9, 2016Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Masahiro Nakano, Mikiyasu Ishikura, Yusaku Shimaoka, Hitoshi Nakagawa, Tetsuya Kaneshiro
