Abstract: A battery case of the present disclosure includes a lower case for housing a battery with the upper side of the lower case opened; and an upper case provided on the upper side of the lower case to cover the battery. The lower case includes a lower case bottom surface on which the battery is placed and a lower case side surface extending upward from the edge of the lower case bottom surface. The lower case side surface includes, on its side where a module terminal of the battery is disposed, a cut part cut downward in such a way that the height of the lower case side surface becomes lower than the height of a position of the module terminal.

Abstract: Configured is a delivery support system including: an available space detection unit that detects an available space that is a space in which a package can be loaded based on an output signal of a package sensor that is attached to a package compartment provided in a delivery vehicle and that detects a three-dimensional region in which there is a package loaded in the package compartment; a determination unit that determines whether a package to be added can be loaded in the available space based on dimensions of the package to be added; and an output unit that outputs a determination result of whether a package can be loaded.

Abstract: A method and device for measuring the quantity of water dampening the face of an offset printing plate in which a light beam is made incident at a suitable angle to the face of the printing plate and the light beam directly reflected from the plate at the same angle with the angle of incidence as well as the light beam diffuse-reflected in the direction normal to the face of the printing plate are independently detected so that an image area and a non-image area on the face of the plate are detected in response to the diffuse-reflected light beam; and the variations in level of the directly reflected light beam is calibrated in response to the diffuse-reflected light beam.
