摘要： In bearing mechanism for a motor spinning a storage disk about a center axis, an interference-fit portion of a shaft is interference-fitted into a through hole of a bushing from an axial lower side thereof such that the shaft is fixed to a rotor hub. The interference-fit portion of the shaft is defined with an upper section, a lower section, and a concave portion. When the shaft is interference-fitted into the bushing, the upper and lower sections engage with the bushing, and the concave portion radially faces an inner surface of the bushing with a gap defined therebetween.

摘要： A random number generator includes a ring oscillator having an EX-OR gate and four inverters together forming a loop. This loop enters stable state for a start signal having the low level and oscillates for the start signal having the high level. When the start signal has a pulse of a width shorter than the loop's delay time, output nodes responsively, sequentially enter metastable state hovering between the high and low levels. The metastable waveform becomes smaller with time and finally disappears. As metastable state cannot be controlled in longevity, it disappears at any random number node. A counter thus outputs a signal serving as true random number data depending on the longevity of the metastable state. A random number generator miniaturized and having reduced power consumption, and of high performance can thus be implemented.

摘要： In wire-cut electrical discharge machining apparatuses that simultaneously perform a plurality of cutting processes by engaging a wire between main guide rollers at a plurality of times, a wire-cut electrical discharge machining apparatus is provided that suppresses vibrations at cutting wire sections, to enable the cutting processes under steady-state accuracy. In addition to the main guide rollers, vibration-damping driven guide rollers or vibration-damping guides are included which form a plurality of cutting wire sections where the vibrations are suppressed by guiding the wire into place, and the positions of the cutting wire sections are thereby defined with respect to nozzles.

摘要： When a CPU proceeds to an interruption process, a value permitting an access to a security-related area is set in a flag register, and when the CPU returns from the interruption process, a value prohibiting an access to the security-related area is set in the flag register. A resource selecting signal generating circuit generates access signals for accessing to various areas in a non-volatile memory and an RAM, in accordance with the flag stored in the flag register. Therefore, when the security-related area is held as an interruption processing area, it becomes possible to prevent an access to the security-related area from a security-non-related program area, and hence, it becomes possible to prevent leakage of security-related information.
