  • Patent number: 11649611
    Abstract: 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.

  • Patent number: 10844886
    Abstract: A hydraulic system includes: a control valve connected to a pump and a tank; a cylinder connected to the control valve by a rod-side and a head-side supply lines; a recycle line connects the rod-side to the head-side supply lines; a recycle valve on the recycle line being opened at a time of extending the cylinder and closed at a time of retracting the cylinder; a switching valve on the recycle line between the recycle valve and the head-side supply line being switched to a first state at the time of extending the cylinder and switched to a second state at the time of retracting the cylinder; a release line branches off from the recycle line at a position between the recycle and switching valves, and connects to the tank; and a release valve closed at the time of extending the cylinder and opened when retracting the cylinder.

  • Publication number: 20160336826
    Abstract: 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.

  • Patent number: 9258636
    Abstract: 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.
