It is legal to look for work while visiting Canada. Obviously, you should always tell the truth to the officer and state your purposes in the country. You would also need to prove to the immigration officer that the plan is to leave Canada within the maximum allowed time and that you will not work in the country without the proper work permit.
Dielectric materials for semiconductor chips. Dielectric material characterize with very low electrical conductivity (one millionth of a mho / cm), in which an electric field can be sustained with a minimal leakage. It can store electrical energy/charge.
Many objects are designed specifically to store elastic potential energy, for example: 1  The coil spring of a wind-up clock. 2  An archer's stretched bow. 3  A bent diving board, just before a divers jump. 4  The twisted rubber band which powers a toy airplane. 5  A bouncy ball, compressed at the moment it bounces off a brick wall.
