The value at which malfunction occurred was

measured after applying shock to the test piece

3 times each in 6 directions along 3 axes.

along 3 axes

. The percentage rate of change is the

average value for all of the samples.

Characteristics were measured after applying vibration

at a frequency of 10 to 55 Hz (single amplitude of 0.75

mm) to the test piece (not energized) for 2 hours each

in 3 directions. The percentage rate of change is the

average value for all of the samples
