    Abstract: A range imaging device includes a light source unit that emits light pulses to a measurement space; a light-receiving unit including a photoelectric conversion element that generates charge according to light incident from the space, a pixel circuit including charge storage units in which the charge is integrated in a frame cycle, and a pixel drive circuit that performs switching operation of transfer transistors to distribute the charge to the storage units for integration at integration timing synchronizing with emission of the pulses; and a distance calculation unit that calculates a distance between object in the space and the light-receiving unit based on charge determined by a first charge integrated in each storage unit. The calculation unit calculates the distance by subtracting a second charge from each first charge, the second charge being noise charge as an integrated charge other than the charge distributed and integrated by the switching operation.

    Abstract: A membrane electrode assembly includes: a polymer electrolyte membrane; a first electrocatalyst layer and a second electrocatalyst layer sandwiching the polymer electrolyte membrane while being in contact therewith; a fuel electrode diffusion layer which is a gas diffusion layer laminated on the first electrocatalyst layer to form a fuel electrode; and an air electrode diffusion layer which is a gas diffusion layer laminated on the second electrocatalyst layer to form an air electrode. The air electrode diffusion layer has a Gurley value of 80 seconds or less in a thickness direction thereof, which is smaller than a Gurley value of the fuel electrode diffusion layer in a thickness direction thereof, the Gurley value indicating air permeability.

    Abstract: An avatar management system includes an avatar registration unit configured to register an available avatar by having a storage unit to store the avatar available in a network service provided to an end user on a network, an authentication information assignment unit configured to assign authentication information to a registration target avatar registered in the avatar registration unit, and an authenticity confirmation unit configured to confirm authenticity of a designated avatar based on an assignment condition of the authentication information to the designated avatar, in accordance with an authenticity confirmation inquiry made by designating the avatar used in the network service.

    Abstract: An optical film includes a transparent substrate having opposite first and second surfaces, a colored layer formed to face the first surface of the substrate, and an optical function layer. A colorant in the colored layer contains at least one of a first coloring material having a maximum absorption wavelength in a range of 470 to 530 nm and an absorption spectral half width of 15 to 45 nm, a second coloring material having a maximum absorption wavelength in a range of 560 to 620 nm and an absorption spectral half width of 15 to 55 nm, and a third coloring material having the lowest transmittance in a wavelength range of 400 to 800 nm is in a range of 650 to 800 nm. A transmittance in one of the absorption wavelength bands of the colorant is 1% or more and less than 50%, and ΔE * ab.
