Abstract: In a digital PLL system, instead of measuring a binarized playback RF signal with a high frequency clock, pulse-length data is generated by using N phase clocks (for example, 16 phase clocks). The pulse-length data is then run-length counted with a virtual channel clock so as to extract data. In this digital PLL system, the number of changing points of an asynchronous signal during an interval between adjacent clocks of the N phase clocks is detected so as to determine phase errors from the detected number of changing points. Phase errors are also determined from the timing relationship between changing points of a signal synchronized with the N phase clocks and each clock of the N phase clocks.

Abstract: A process of producing a semiconductor device having a highly reliable groove isolation structure with a desired radius of curvature formed at the groove upper edge and without formation of any step. The device is produced by reducing the stress generation around the groove upper edge of an element isolation groove on a semiconductor substrate, thereby optimizing the shape of an element isolation groove and making the device finer and improving the device electric characteristics.

Abstract: A phase-locked-loop device includes a clock generator for generating a reference clock based on a binarized playback signal and a frequency of run-length data and for generating N-phase clocks using the reference clock, a pulse-length measuring device for measuring a pulse length of the binarized playback signal using the N-phase clocks to output pulse-length data, and a run-length-data extracting device for counting the pulse-length data based on a virtual channel clock to extract run-length data. Pulse-length data is generated using the N-phase clocks (e.g., 16-phase clocks). The pulse-length data is counted based on the virtual channel clock to extract run-length data. Thus, it is not needed to generate a high-frequency clock, and the operating frequency is maintained sufficiently low.

Abstract: A communication terminal device, a communication system, a communication method, and a program which allow efficient communication processing via multicast communication, along with power saving. The communication terminal devices includes a wireless communication unit comprising: a multicast ACK generating unit which makes it possible to transmit packets having an ACK function; a multicast ACK analysis unit which analyzes received packet data for ACK information; wireless transmission and reception units which perform modulation and demodulation processing; and a central control unit and a timing control unit which control these components. The ACK function is thus implemented by multicast packets in multicast communication. This makes it possible to check if its own transmission data is received by other stations (communication terminals).

Abstract: Bearings (5, 7) fixed to the two ends of a rotation shaft (2) of a motor/generator are pressurized by plate springs 15, 17. The plate springs (15, 17) absorb the deflection off the rotation shaft (2) due to external vibration by the extension and contraction. An effective gaps L is set to value at which the bearings (5, 7) do not collide with the housing (9) in the most compressed state of the plate springs (15, 17). By this setting, the effective gap L is set to a value larger than the maximum amplitude in the direction of the rotation shaft (2) due to the external vibration.
