A printer comprises a receiving section which receives printing jobs from a networked personal computers, a storage section which stores the received printing jobs, and a printing section which executes a printing job extracted from the storage section. The grip is a multilayer laminate having an inner layer made from an elastomeric material having high energy absorption and vibration damping characteristics. A channel layer extends in the second direction along the stack of the plurality of cell gate electrodes, and a variable resistance layer contacting the channel layer. The power is supplied from the battery 1 to the main circuit 4. The signal from the amplifier is demodulated and processed to calculate physiological parameter based on the change in the excitation signal. Preferably, during the post-deposition plasma treatment, RF power is applied only to the showerhead counter-electrode and none to the pedestal supporting the wafer, thereby preventing charging of the wafer.
