A linear oscillatory actuator includes a magnetic pole forming portion that includes an electromagnet and a base, magnetic blocks each of which includes a magnet attracted or repelled by the electromagnet to reciprocate, elastic suspensions for supporting the magnetic blocks, and at least one coupling spring portion that couples the magnetic blocks reciprocatably. Each of the elastic suspension includes upper and lower extending portions, and elastic planar portions integrally provided between the upper extending portions and the lower extending portions, respectively. Depressed portions are formed at continuous portions between the upper extending portions and the elastic planar portions, respectively, and each of the depressed portions is depressed toward the magnetic blocks. While the magnetic blocks reciprocate, Stress concentration on the continuous portions can be mitigated by the depressed portions. Therefore, the elastic planar portions can be prevented from being damaged without becoming large in size.

A base transceiver station receives first and second reception power values from a plurality of user equipments. The first reception power value is a reception power value at which a user equipment receives a radio signal from another base transceiver station without using a reception beam formation function that allows a radio signal transmitted from a predetermined direction to be selectively received with increased reception sensitivity. The second reception power value is a reception power value at which a user equipment receives a radio signal from another base transceiver station using the reception beam formation function. The base transceiver station selects, from among the plurality of user equipments, a user equipment to be handed over based on the first and second reception power values, and performs handover processing on the selected user equipment.

A water jet propulsion watercraft includes a hull, a cockpit arranged at a hull center and including a periphery that is surrounded by a wall surface, a rear deck arranged at a hull rear portion at a rear of the cockpit and including a rear water-access area that is open to the rear, a saddle type watercraft operator seat arranged in the cockpit, a jet propulsion device attached to the hull and arranged to apply a propulsive force to the hull by sucking in water from surroundings and jetting the water, and an engine attached to the hull and arranged to apply a driving force to the jet propulsion device. The saddle type watercraft operator seat may extend in a front/rear direction of the hull and be arranged to divide an interior of the cockpit into two regions at the right and left.
