Abstract: A photothermographic element has on a support a photosensitive layer containing an emulsion of silver halide fine grains having a mean equivalent spherical diameter of 10-50 nm. (1) The silver halide emulsion has been formed independent of an organic fatty acid silver salt rather than by partial halogen conversion of a non-photosensitive organic silver salt, and mixed with the organic silver salt before coating. (2) A reducing agent for silver ion is contained. (3) The silver halide fine grains have been chemically sensitized in the presence of a spectral sensitizing dye. The element is improved in sensitivity and restrained from fog increase during storage in daylight after processing.

Abstract: A seated-state detection sensor is disposed in a seat portion of a seat cushion of a passenger seat. The seated-state detection sensor is divided into three parts, that is, a first seated-state detection sensor, a second seated-state detection sensor and a third seated-state detection sensor, which are arranged in this order from the rear side of the vehicle. The first seated-state detection sensor and the second seated-state detection sensor are designed to determine whether or not there is a passenger seated. The second seated-state detection sensor and the third seated-state detection sensor are designed to detect forward displacement of the passenger.
