Abstract: High-accuracy multimodal biometric authentication of a plurality of body organisms is achieved while suppressing postural fluctuation when the plurality of body organisms are captured. An authentication system stores feature quantities for body organisms in association with users and performs biometric authentication on the basis of images from a capture device. The capture device photographs a first body organism of a first user during a first period and captures a second body organism and a third body organism of the first user during a second period. The authentication processing device calculates a first feature quantity from the first body part photographed during the first period, respectively calculates a second feature quantity and a third feature quantity from the second body organism and the third body organism captured during the second period, and compares with the feature quantities for the body organisms of each user stored at the storage device.

Abstract: A photographing apparatus includes: an imaging unit which is arranged at a position opposed to a plurality of fingers to be presented, and is configured to image the plurality of fingers; and a plurality of light sources which are arranged in plurality in an array direction of the plurality of fingers, and are configured to irradiate the plurality of fingers with light from an outside of an opposing region in which the imaging unit is opposed to the plurality of fingers toward an inside of the opposing region.

Abstract: An electrostatic precipitator includes: a casing attached to a housing a fixing member a supporter a device body supported by the supporter and is detachably attached to the supporter; and a hook member supporting the device body. The device body includes a handle protruding in a first direction and a pair of protrusions protruding from both end side surfaces of the delivery body in a second direction, the supporter includes a pair of first support portions respectively supporting the pair of protrusions by hooking the pair of protrusions, the hook member includes a hook portion supporting the handle the handle includes a pair of extending portions protruding in the first direction and a grip portion connecting the extending portions, the hook portion supports the grip portion from below, and the hook member is attached to the supporter so as to be slidable in the first direction.

Abstract: A semiconductor device manufacturing method includes: a process of forming an isolation trench on the surface of a semiconductor substrate; a process of forming a thermally-oxidized film on the surface of the isolation trench; a process of depositing a silicon oxynitride film on the semiconductor substrate via the thermally-oxidized film; a process of heat-treating the silicon oxynitride film in an oxidizing atmosphere; and a process of etching the top of the thermally-oxidized film and the heat-treated silicon oxynitride film.
