Part of the latency from memory read or write operations is for data to be input to or output from the data latches of the memory via an IO bus. The heat bridge may take the form of a structural wall coupled to, but preferably integrated with, the chassis to facilitate conductive heat transfer into a chassis panel. The flange portion is clamped by a first and a second clamp, arranged in the longitudinal direction, and one first clamp is a tight clamp for holding fixedly the flange portion and a plurality of second clamps are loose clamps for clamping loosely the flange portion, allowing the article to be heat treated to be convex on the side of the heated hardening region. If such a medium-does not exist, then the set of available media is canvassed to locate an alternative medium. The reliability is larger when pixels of the third group are more located in shape of a straight line on the plane. The deenergizing coil is included in series with the motor for bringing the relay switch element in a non-conductive position when a current through the deenergizing coil and the motor exceeds a threshold value.
