|
| Notes |
|
| (1) | This subclass covers: |
|
| – | electrostatic generators, motors, clutches, or holding devices; |
|
| – | other non-dynamo-electric generators or motors; |
|
| – | holding or levitation devices using magnetic attraction or repulsion; |
|
| – | arrangements for starting, regulating, braking, or otherwise controlling such machines unless in conjoint operation with a second machine. |
|
| (2) | Attention is drawn to the Notes following the titles of class B81 and subclass B81B relating to "micro-structural devices" and "micro-structural systems". [7] |
|
| (3) | Specific provision for generators, motors, or other means for converting between electric and other forms of energy also exists in other subclasses, e.g. in subclasses H01L, H01M, H02K, H04R. |
