Abstract: A photosensor includes a light projection unit, a light receiving unit, a determination unit that determines a magnitude relation between a received light quantity of the light receiving unit and a threshold value set for the received light quantity; and a threshold value setting unit that sets the threshold value of the received light quantity. The threshold value setting unit calculates for each of a plurality of different wavelength regions, a contrast difference that is a difference between a received light quantity obtained when projection is performed on a detection target on a surface of a workpiece and a received light quantity obtained when projection is performed on a background on the surface of the workpiece, and updates the threshold value based on the contrast difference for a wavelength region among the plurality of wavelength regions in which the contrast difference has a maximum value.

Abstract: Provided is a method which comprises: an attaching step of attaching a pair of installation jigs, respectively, to right and left opposite lateral portions of a support member; a clamping step of clamping the clampable surface portion of each of the installation jigs by a clamping unit of a transfer device; a temporarily mounting step of transferring the instrument panel module to the front of the passenger compartment by the transfer device to temporarily mount each of the right and left mounting brackets to a sidewall of a vehicle body; and a fastening step of, after the temporarily mounting step, detaching the installation jigs from the support member, and fastening each of the right and left mounting brackets to the sidewall of the vehicle body in the vehicle width direction by a fastening bolt.

Abstract: Provided is a surface protection film having a hard-coat property, an anti-glare property and transparency as well as a sufficient weather resistance property. A surface protection layer is provided on at least one surface of a substrate film, the surface protection layer is formed by a cured paint comprising an ionizing radiation curable resin composition, a matting agent, an ultraviolet ray absorbing agent, a dispersant and inorganic fine particles having an average primary particle diameter of 50 nm or smaller whose surfaces are subjected to a hydrophobization treatment with dimethyldichlorosilane. The inorganic fine particles are included by 200 parts or more by weight with respect to 100 parts by weight of a dispersant. The inorganic fine particles can be silica.
