Abstract: A terminal includes a communication unit configured to perform communication to which dual connectivity is applied with a base station, a receiving unit configured to receive signaling indicating whether terminal-triggered secondary cell group activation or deactivation is enabled from the base station, a transmitting unit configured to transmit a response to the signaling to the base station, and a control unit configured to perform the secondary cell group activation or deactivation based on the signaling.

Abstract: A terminal includes a transmitting unit that transmits a signaling message including information indicating a context to be established with a base station when there is one device corresponding to a transmission source address of the context to be established with the base station, the one device being connected to the terminal; and a control unit that attaches, to data, a compressed header corresponding to the context, when the data received from the one device is to be transmitted after transmitting the signaling message, wherein the transmitting unit transmits, to the base station, the data to which the compressed header is attached, the data not including a context identifier for identifying the context.

Abstract: A terminal including: a reception unit configured to receive, from a base station apparatus, information instructing not to perform a random access procedure even when an event that triggers the random access procedure occurs; and a control unit configured to determine not to perform the random access procedure when the event occurs based on the information.

Abstract: To derive a feasible solution for an operation plan problem for storage tanks for storing liquefied natural gas, which is a complicated mixed-integer non-linear problem, given tank initial state information, reception plan information, and feed plan information, two solving processes are executed alternately two or more times, respectively: a first solving process that replaces a mixed-integer non-linear programming problem with a mixed-integer linear programming problem by linear approximation of a non-linear expression in non-linear constraints containing the non-linear expression, and solves the problem to derive provisional solutions or final solutions for a reception pattern that prescribes a storage tank that is to receive liquefied natural gas, and a discharge pattern that prescribes a storage tank that is to discharge liquefied natural gas, and a second solving process that replaces a mixed-integer non-linear programming problem with a continuous non-linear programming problem by provisionally fixing

Abstract: An automatic transmission provided with a power take-off mechanism friction clutches and planetary gears for multiple gear ratio changes. A front friction drum houses the friction clutches which are coaxially and radially disposed with respect to each other, and a step portion is formed on a radial outer side of the drum for operating a radial outer one of the friction clutches and setting a power take-off drive gear.

Abstract: An oil pressure clutch mechanism of an automatic transmission is comprised of at least two clutches interposed coaxially in a front drum. An oil circuit for controlling the clutches is formed in the front drum in relation to an oil circuit in an oil pump cover. The oil circuit includes circular oil grooves formed between an outer face of the oil pump cover and an inner face of the drum. A circular drain groove is disposed axially between the circular oil grooves to receive oil leaked therefrom. A drain passage is formed in the front drum for conducting leaked oil from the drain groove to a location external of the front drum. The outlet end of the drain groove is spaced farther from the axis than is the inlet end thereof, whereby leaked oil is discharged through the oil drain passage under the influence of centrifugal force.
