  We report observations of gamma-ray emissions with energies in the 100 TeV
energy region from the Cygnus region in our Galaxy. Two sources are
significantly detected in the directions of the Cygnus OB1 and OB2
associations. Based on their positional coincidences, we associate one with a
pulsar PSR J2032+4127 and the other mainly with a pulsar wind nebula PWN
G75.2+0.1 with the pulsar moving away from its original birthplace situated
around the centroid of the observed gamma-ray emission. This work would
stimulate further studies of particle acceleration mechanisms at these
gamma-ray sources.
