An electrode manufacturing method includes: a coating process of applying a coating material to a metal foil while the metal foil is fed forward to form a coated foil; and a drying process of drying the coated foil by heating while the coated foil is fed forward to pass through a drying oven of a drying machine placed in line on a feeding path. In mobile device MS, CPU 6 writes in key information area 73 of RAM 7 key information for identifying a Java application which is being run using KVM program 84, using OS software 82 and JAM program 86 stored in nonvolatile memory 8. The switching method according to the embodiments of the present invention includes: sending to a UE a switching indication information that requires the UE to switch a TTI; and receiving from the UE a switching confirmation information with which the switching indication information is confirmed. A receiver detects a transition in the signal on one of the three wires, identifies the transition from the previous and current 3-bit symbols and determines the information token associated with the transition. The value of the signal or any change in the signal is compared to a threshold value to ascertain when the piston head is in proximity to the resin so that the motion of the piston toward the resin can be halted before contact pressure from the piston head damages the resin. The mobile unit receiver may be used to identify the frequency with lowest signal level at the underlay station.
