  • Patent number: 9073427
    Abstract: In a series mode, a clutch rotational speed difference ?N is calculated, and when the clutch rotational speed difference ?N is within a first predetermined range R1 it is determined whether a sticking determination timer t1 indicates a first predetermined time t1 or longer. When a closed sticking timer t indicates the first predetermined time t1 or longer, fuel cut is performed, and the clutch rotational speed difference ?N is re-calculated. When the closed sticking timer t indicates a second predetermined time t2 or longer, and the clutch rotational speed difference ?N is within a second predetermined range R2, it is determined that there is closed sticking of a clutch. When the closed sticking timer t indicates less than the time t2, and the clutch rotational speed difference ?N is out of the second predetermined range R2, it is determined that there is no closed sticking of the clutch.

  • Patent number: 8965165
    Abstract: A multicore fiber includes a cladding and a plurality of core elements which is provided in the cladding and includes a core, an inner cladding layer that surrounds the core, and a low-refractive index layer that surrounds the inner cladding layer and has a lower average refractive index than the cladding and the inner cladding layer. The plurality of core elements is arranged such that a specific core element is surrounded by three or more core elements, and a low-refractive index layer of a partial core element of the plurality of core elements is configured to have larger light confinement loss in the core than low-refractive index layers of the other partial core elements.

  • Publication number: 20150011205
    Abstract: Upon detecting an opportunity to release E-RABs related to mobile stations, a mobility management entity transmits a single E-RAB release information message that collectively specifies E-RABs to be released to a base station communicating with the mobile stations. Subsequently, upon receiving the E-RAB release information message, the base station transmits a single E-RAB release information acknowledge message to the mobility management entity. Upon receiving the E-RAB release information acknowledge message, the mobility management entity updates information related to the E-RABs so that the information indicates release of the E-RABs.

  • Publication number: 20150003254
    Abstract: A radio communication system includes at least one user equipment, base stations, and a control station. After expiration of the timer started after establishment of the data bearer, the base station selects the access point base station for the user equipment on the basis of the voice congestion levels and indicates the access point base station to the user equipment if the voice bearer has been established, and selects the access point base station for the user equipment on the basis of the data congestion levels and indicates the access point base station to the user equipment if the voice bearer has not been established.

  • Publication number: 20140180516
    Abstract: A traveling mode switching controller of a hybrid electric vehicle has a velocity detection unit, a state-of-charge detection unit, and a switching control unit for selectively switching among first to third traveling modes. In the first traveling mode, an engine is deactivated and a drive motor is activated to actuate drive wheels. In the second traveling mode, the engine activates a generator to activate the drive motor. In the third traveling mode, the engine activates the drive wheels. When the state of charge is less than a first state of charge, the switching control unit performs switching between the second traveling mode and the third traveling mode at a first velocity. When the state of charge is the first state of charge or more, the switching control unit performs switching between the first traveling mode and the third traveling mode at a predetermined velocity higher than the first velocity.
