  • Publication number: 20130227690
    Abstract: A program analysis system that analyzes a program while adjusting time elapse velocity in program execution environment sets analysis conditions such as time elapse velocity in the execution environment, program execution start time and execution termination time, adjusts the time elapse velocity and the program execution start time according to the determination of an analysis manager, executes the program till the execution termination time, monitors the execution environment, acquires an action record of the program, analyzes the action record, and clarifies the behavior of the program. Further, the program analysis system resets the analysis conditions based upon a result of analysis, re-analyzes, monitors communication between a sample and an external terminal, and varies the time elapse velocity set by the analysis manager to prevent time-out from occurring in communication.

  • Patent number: 6256277
    Abstract: An information recording apparatus for injecting an energy beam into a recording medium to form locally a region different in physical properties from a non-recording region to thereby record information, has a drive for driving an energy generation source for changing the number of injected energy pulses in a mark forming period in accordance with the mark length so that the interval between arbitrary two points of the change of injected power level at the time of information recording is substantially set to be longer than a half of a detection window width in order to make it easy to drive a recording energy generation source to thereby form said mark accurately and speedily and, at the same time, in order to secure a sufficient time required for cooling the recording medium.
