  • Patent number: 10786847
    Abstract: A hydraulic forging press machine and a control method, whereby surging of the forging load or dead zones where the forging speed goes to zero is suppressed, and forging is performed with high precision throughout a wider range than the prior art, from low to high load. Pressure cylinders have a main pressure cylinder configured so working fluid is supplied during forging, and secondary pressure cylinders are configured so supplying and stopping of the supply of working fluid thereto are switched in response to the forging load, head-side hydraulic chambers of the secondary pressure cylinders being connected to a head-side hydraulic chamber of the main pressure cylinder via electromagnetic switching valves. Only the main pressure cylinder is used until the forging load exceeds a set load, and the number of secondary pressure cylinders used is sequentially increased as the forging load increases after the forging load exceeds the set load.

  • Patent number: 9578662
    Abstract: In order to implement handover to a femto cell without making any modification to UEs, a gateway (50) relays traffic between a core network (60, 70) and a plurality of base stations (20_1-20_4) that are respectively incorporated into the core network (60, 70) through a public network. The gateway (50) generates an RRC Connection Release message for prompting establishment of a new RRC connection, when it is notified from the core network (60, 70) that a mobile station (10) is handed over to any one of the plurality of base stations (20_1-20_4). Then, the gateway (50) causes the core network (60, 70) to instruct a control device (40), which has established an RRC connection to the mobile station (10), to transfer the RRC Connection Release message to the mobile station (10).
