  Continuum observations at 350um are presented of seven nearby elliptical
galaxies, for which CO-gas disks have recently been resolved with
interferometry mapping. These SHARCII mapping results provide the first clearly
resolved far-infrared(FIR) to submillimeter(submm) continuum emission from cold
dust (with temperatures 32K > T > 22K) of any elliptical galaxy at a distance
>40Mpc. The measured FIR excess shows that the most likely and dominant heating
source of this dust is not dilute stellar radiation or cooling flows, but
rather star-formation, that could have been triggered by an accretion or merger
event and fueled by dust-rich material that has settled in a dense region
co-spatial with the central CO-gas disks. The dust is detected even in two
cluster ellipticals that are deficient in HI, showing that, unlike the HI, cold
dust and CO in ellipticals can survive in the presence of hot X-ray gas, even
in galaxy clusters. No dust cooler than 20K, either distributed outside the CO
disks, or co-spatial with and heated by the entire dilute stellar optical
galaxy (or very extended HI), is currently evident.
