IPC: G06F19/00
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To predict the electric, magnetic, and dynamic properties of a high polymer martial by calculating time correlation functions for plural time origins and calculating their means by utilizing the fact that a time origin is arbitrary in a thermal equilibrium state. SOLUTION: Assuming that a molecule system is thermal equilibrium at time T0 , the phase point trajectory of the molecule system from time T0 to time Tf represents the thermal oscillatory state of the molecule state. In the thermal equilibrium state, the time origin is optionally set and the time correlation function can be calculated with the origin at any time. Consequently, (n) time origins are set at internals δt from time T0 , the time correlation function is calculated from an equation II for each time origin T0 +idt, and their means is calculated according to an equation III to fined a time correlation function regarding the physical quantity A defined by an equation I. Consequently, the time correlation function which is dominant to high polymer properties can easily be obtained.

Abstract: PURPOSE:To realize the simplification of a data base program and the low pricing of a terminal system, by preparing a bit of information and a function required for the error recovery of a data base on a terminal side when a fault is generated in the data base on the terminal side. CONSTITUTION:When the fault is generated in a DBMS6 at a certain time, the DBMS6 informs the generation of abnormality on the db space of the terminal to a DBMS3 existing on a host computer by a command (b). At this time, the DBMS3 transmits the content of a corresponding db space to the DBMS6 of the terminal with a format (c), and generates the db space at the time of obtaining backup in the terminal. Next, the DBMS3 converts the data to an SQL command starting from the data with the earliest time included in a log data, and transmits it to the DBMS6 of the terminal with a format (a). The DBMS6 performs the recovery of the db space by processing the data. In such a way, it is possible to obtain a data base with high reliability in a terminal equipment with the minimum constitution.
