A card edge connector includes an insulation body, a first assembly part, a second assembly part, a plurality of first terminals and a plurality of second terminals. While an inner head’s gramload is being measured, an adjacent inner head is configured in a supported state, and the cam-rod corresponding to the supported head transmits some additional force to the head whose gramload is being measured, e. The polymeric dispersing agent may be a water soluble polymer having a molecular weight of at least 2000 Daltons. The controller arranges memory assignments of the basic memory in accordance with a first memory map to perform operations of the copying and facsimile functions when the expansion memory is not mounted to the socket. It is also found that blending an electrochromic polymer with a non-coloring electroactive material allows for greater design in preparing electrochromic devices as it enables the use of a higher amount of typically low coloring anodic materials due to increased need for charge balancing.
