The present invention is a heat-resistant Ni-base alloy including a Ni\u2014Ir\u2014Al\u2014W alloy having essential additive elements of Ir, Al, and W added to Ni, wherein the heat-resistant Ni-base alloy includes Ir: 5. The frequency synthesizer includes a single PLL outputting a reference signal that is fed to a plurality of dividers coupled in sequence. The mobile communication device receives, via the network, control information of a management server causing the service providing apparatus to execute the service and transmit the same to the service providing apparatus. The scan type may include single scan, multiple scan, or multiple scan with overlap. The negative electrode for a rechargeable lithium battery minimizes volume expansion and imparts good cycle-life characteristics and initial formation efficiency. The analyzer unit is designed to analyze electrocardiogram signals and marker signals in combination, such that the analyzer unit detects relevant particular features on the basis of predefined criteria; assigns a priority to a detected particular feature; and generates an analytical report containing at least a listing of the detected particular features.
