I believe the official term for a semi-integrated headset is "zero-stack".
Chris King's traditional press-in headsets, both threaded and threadless, are a bit different from others in that the bearing cartridges are sort-of "staked" into the cups and can't be removed or replaced. They can be cleaned in place by removing the seals, relubing the bearings and replacing the seals but when they are shot you have to replace the entire headset. It's good thing CK has a long warranty and uses exceptionally high quality bearings.
