Abstract: Provided are a connector and a connector assembly which can be attached for use to a bendable object of interest such as clothing. A connector, which is mated with a mating connector, is provided with a plate-shaped housing, electrically conductive contacts arranged on the housing, and a plurality of retainer members formed from a magnetic metal and arranged in the housing. When the connector is mated with the mating connector, the retainer members are attracted to a magnet that the mating connector has so as to hold the mating state. The housing is formed from a bendable insulating rubber, and the plurality of retainer members are spaced apart from each other in the longitudinal direction (the X direction) parallel to a front surface of the housing.

Abstract: A lock part for locking an inserted state of a flexible printed circuit (FPC) is provided, in a housing of a connector, on both sides of an insertion portion in a width direction. Each lock part has an arm portion and a projected portion formed on an inner side portion of the arm portion in the width direction and is protruded into the insertion portion. The arm portion has a cantilever shape with a stationary end and a free end and extends, in a depth direction, to the free end from an insertion side portion on an FPC insertion side, and can be elastically deflected outward in the width direction. The projected portion has tilted portions tilted relative to the depth direction toward the free end and the insertion side portion, and is detachably engaged with a notch on a side of the inserted FPC in the width direction.

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
