Disclosed herein is a golf ball with a solid core having a PGA compression of 55 or less and an outer cover layer having a Shore D hardness of at least 60, the ball having a PGA compression of 80 or less. The first intensity and the first reference intensity are of radioactive nuclides generated by a neutron capture reaction of a heavy nuclide or a fission product nuclide. The piezoelectric actuator receives the charge packets and, by its capacitive nature, integrates the charge packets to shape the waveform of the drive signal. At this point, the ARQ connection can be maintained without superfluous ARQ resets even when no ARQ data blocks are being sent. The carriage frame moves with respect to the boomer assembly frame to move the blowout preventer over a wellhead.
