An image processing apparatus which is capable of suppressing an increase in the circuit size of buffers between data-processing circuits, thereby enabling an associated component thereof to be implemented by hardware. During installation of the mount assembly, the top and bottom collars are positioned on opposite sides of the vehicle curved section, and an externally-threaded tubular connector is inserted through through-holes in the top and bottom collars and through an opening formed in the curved section of the vehicle. The present invention further provides methods for inhibiting the discharge of nematocysts or polar capsules, comprising applying to the skin of a subject prior to contact with the nematocyst or polar capsule a compositions comprising at least one cation selected from the group consisting of Ga+3 and La+3.
