Abstract: In a location estimation device, a change detection unit detects a point of change in the width of a roadside structure as a width change point. A width correction unit calculates a width deviation between a first relative location of the roadside structure on a map data segment and a second relative location of the roadside structure obtained based on shape information of the roadside structure in the width direction of a vehicle.

Abstract: A tip end part of a main arm member of a Scott Russell mechanism is enabled to be brought close to a base end part of a sub arm member. A Scott Russell mechanism device is formed into a boomerang-like shape such that a main arm member coupled to a sub arm member is curved to detour a coupling position. Thus, when the coupling angle is changed so that a base end part of the main arm member and a base end part of the sub arm member are most separated from each other, a tip end part of the main arm member can be moved close to right beside the base end part of the sub arm member. With the Scott Russell mechanism device, a moving range of the tip end side of the main arm member can be enlarged.

Abstract: A joint unit pivotably coupled to a tip end part of a main arm member of a Scott Russell mechanism is pivoted in two ways. A Scott Russell mechanism device pivotably couples a main arm member and a sub arm member to each other, as well as it pivotably couples a joint unit to a tip end part of the main arm member. Moreover, by providing a pivot driving unit to the main arm member, as well as providing a fourth motor and a drive transmission mechanism unit to the sub arm member, the Scott Russell mechanism device can switch between pivoting the joint unit associatively a change of a coupling angle of the arm members and pivoting the joint unit by the drive of the fourth motor.

Abstract: Provided are a coherent light source apparatus and a projector. A first light emission region is formed on basis of a coherent light source; a first optical system projects light derived from a first light emission region to form a second light emission region; a light deflection section deflects a bundle of rays in vicinity of the second light emission region; a second optical system downstream of the light deflection section; and a light mixing section downstream of the second optical system that mixes components of angles and positions of rays incident on an incident end. The second optical system forms an image conjugate to the first light emission region and a third light emission region substantially conjugate to an exit pupil of the first optical system. The light deflection section continues to cause a direction in which the bundle of rays is deflected to be continuously changed.

Abstract: A coherent light source apparatus includes a coherent light source, a first optical system, a light deflection unit, a second optical system and a light mixing unit disposed in that order. The coherent light source forms a first light emission region, and light projected therefrom forms a second light emission region near the light deflection unit, which deflects light flux from the second light emission region.

The light deflection unit is configured to continuously changing a direction in which the light flux is deflected, thereby reducing speckling in light emitted from the light mixing unit.

Abstract: In a rotation device using a hydraulic actuator, a rotation angle range is increased. A placement member rotatably coupled to a rotary member has a projecting part on an upper face. A hydraulic actuator is arranged on a projecting face of the projecting part; the actuator and the rotary member coupled with a wire material. The projecting part is formed such that it becomes higher from a leading edge on the side of the rotary member to an intermediate portion in the longitudinal direction, and becomes lower from the intermediate portion to a trailing edge. Thereby, when fluid is supplied to the actuator and shortens the actuator length, a tip of the actuator moves along the projecting face of the projecting part, and is located high, separated from the upper face of the placement member such that the rotation angle range of the rotary member becomes large.
