Exposure control for a solid-state imaging apparatus can be completed in a short time. The data normalization system includes changes to internal data representations of a database system as well as functional processing changes that leverage normalized internal data representations for a high density of independently executable CPU instructions. Extruded impact dispersing deformable sections with a smaller rigidity than the associated side sills are provided on the inboard sides of the sills and arranged to smooth buckling and disperse collision energy. There is a labial spout provided in its internal lower base with two coupling devices, device and device. The circulating mechanism is mounted between the trays and the reservoir.
