Method for producing acrylic resin-coated silica particle dispersion

During autonomous driving of a vehicle, useful Information is presented to an occupant. An image generator in driving assistance device generates a first image representing an action the vehicle is capable of executing depending on a travel environment during autonomous driving and a second image representing a basis of the action. Image output unit outputs the first image and the second image generated by the image generator to notification device in the vehicle in association with each other. The action vehicle is capable of executing may be selected from among action candidates by a driver.

Driving assistance method, and driving assistance device, driving control device, vehicle, driving assistance program, and recording medium using said method

There is provided a coating composition with excellent storage stability, and with excellent mar resistance for obtained coating films. The coating composition comprises a hydroxyl group-containing resin (A), a curing agent (B) and a dispersion of acrylic resin-coated silica particles (C), the dispersion of acrylic resin-coated silica particles (C) being an acrylic resin-coated silica particle dispersion obtained by reacting silica particles with a polymerizable unsaturated group (c1) and a polymerizable unsaturated monomer (c2) in a mass ratio of (c1):(c2)=20:80 to 90:10, the polymerizable unsaturated monomer (c2) including a specific polymerizable unsaturated monomer (c2-1) as at least a portion of its components, and the molecular weight of the resin covering the silica particles being 400 to 6000.

The image evaluation method and apparatus check for image abnormalities. In the method and apparatus, a Mahalanobis space is set preliminarily using a specified characteristic quantity extracted from specified image data. Then, Mahalanobis distance in the Mahalanobis space using image data read from an image to be evaluated. The calculated Mahalanobis distance is compared with a specified threshold value to check for the image abnormalities in the image to be evaluated. The method and apparatus provide a quantitative criterion in checking for abnormal image and enable image evaluation to be performed in a simple and rapid manner to realize efficient inspection.

Method and apparatus for evaluating image

A device for containing a radiation recording medium includes an opening through which the recording medium is placed and a light shutting plate for closing the opening to prevent light from penetrating into the casing. A light shutting plate is provided integral with a handle. A locking mechanism is provided for bringing a casing into locking engagement with the light shutting plate. Since the device is moved by holding the handle with the light shutting plate locked on the casing, there is no possibility that the film will be inadvertently exposed to light with the shutter plate left unclosed.
