Abstract: An optical deflector includes a movable portion having a mirror plane, a fixed portion, a pair of combined torsion bars connecting the movable portion and the fixed portion to each other so that the movable portion can be rotationally displaced about a rotation axis with respect to the fixed portion, and a driver to drive the movable portion. Each combined torsion bar includes a plurality of torsion bars extending to be parallel to the rotation axis and a plurality of connecting bars, each of the connecting bars connecting one ends of each adjacent two of the torsion bars to each other. A torsion bar farther from the rotation axis has higher torsional rigidity than a torsion bar closer to the rotation axis.

Abstract: A portable device including: a housing including a bottom wall section and a frame-shaped peripheral wall section provided on the bottom wall section; a pressure-sensitive touch panel including a bonding section and a contact section, the bonding section being bonded to the peripheral wall section and the contact section being surrounded by the housing and positioned inside from the bonding section; and a control board that is electrically connected to the touch panel through the contact section.

Abstract: A work vehicle (2) having an implement position controller (50). Set elevations and orientations of the work implement (5) can be preselected and changed. The controller (50) automatically positions the implement (5) in the desired elevation and orientation. Means (51) for preventing the work implement (5) from falling into the ground are also provided.
