Abstract: A vehicle seatbelt device of an embodiment includes a recognizer that recognizes circumstances around a vehicle, a steering operator that is able to adjust steering of the vehicle, a vibrator that causes a portion of the steering operator to vibrate, a seatbelt that restrains a portion of the body of an occupant of the vehicle, a tension adjustment mechanism that is able to adjust the tension of the seatbelt, and a controller that controls the vibrator and the tension adjustment mechanism on the basis of the circumstances recognized by the recognizer.

Abstract: A camera module (1) which includes a lens (3); a spring member (9a, 9b) which elastically urges the lens (3) toward an initial position along an optical axis direction; an electromagnetic drive means (11) capable of driving the lens (3) along the optical axis direction by producing an electromagnetic force against an urging force of the spring member (9a, 9b); and a control means (12) configured to control a drive current supplied to the electromagnetic drive means (11), wherein the spring member (pa, 9b) contains 2.9% to 3.5% by mass of Ti, with the balance being copper and inevitable impurities, and has a Vickers hardness equal to or greater than 350.

Abstract: An underground continuous wall building method and apparatus in which a chain cutter 2 provided with excavation blades is obliquely mounted on a running carriage 1. Slanting continuous trenches G1, G2 are excavated by moving the running carriage 1 in a transverse direction while rotating the cutter 2 with the cutter 2 obliquely placed in the ground, and a water cutoff material is poured into the excavated continuous trenches G1, G2 and solidified therein to build slanting continuous walls R1, R2 in the ground.
