A cryptography module includes a key store having a plurality of storage locations for storing a key as k key fragments including a plurality of random key fragments and a remainder key fragment. Since the speed of the synchronous reluctance motor is controlled by detecting the current and the voltage supplied to the synchronous reluctance motor, rather than using an encoder or a hall sensor, a production cost of the synchronous reluctance motor can be reduced. The intravascular flow modifier and vascular reinforcement device can be provided with an outer covering that can be formed as a fiber, and can be woven, or can be formed as a ribbon wound about the intravascular flow modifier and vascular reinforcement device. 5 parts by weight of Component A and 0. The wafer processing may continue if k is in specification or the needed compositional change in the film may be extracted from the measured value of the k and the established dependence of k on the composition of the film for out-of-spec k values.
