We have developed special type of fatigue testing machines in rotating
bending, in which four specimens can be tested simultaneously.
Thus a series of fatigue tests even in gigacycle regime can be carried
out within a reasonable period.
We have developed Nail-Testing machine to all of Li-ion battery.
This testing machine is equipment for doing the trial examination of "the
compulsive internal shorts" which is one of the safety assessment
examinations of a lithium-ion battery.
