Title: Monitor method for unstableness in output of atomic reactor
Inventor: SUZUDO TOMOAKI
IPC: G21C17/00
Filed: 1992-09-11
Abstract: PURPOSE:To enable unstableness in output to be monitored by evaluating the stableness of the output of an atomic reactor from the view point of a Khaos theory based on the dimensional measurement of time series data so as to monitor output. CONSTITUTION:Time series data Ui is supposed to be stored in a memory within a computer. Any attractor can be obtained from limited time series data, however, an orbit in the (d)th dimensional space is reconstituted based on time delay in time series data so as to allow the orbit to correspond to an approximation. When let the reconstituted orbit be Xi, the orbit is represented by a formula I. A parameter (d) in the formula I is so determined that the maximum delay in oscillation is to be more than 1/4 of an oscillation period. Next, the integration C(r) of the distance correlation function of a point over the attractor is computed using a formula II. In the formula, Xi represents the position of a point over the attractor, (r) represents the length of correlation, and N represents the number of paired points over the attractor. The inclination of this correlation function in a logarithmic scale is computed by a formula III, and it is displayed by a graph in abscissa in term of (r). A range where the graph is flat and the value of (r) is maximum, is selected, and the value of the graph corresponding to the range is to be the value of the dimension. If the system is stable, the dimension is to be O, if the system behaves periodically, the dimension is to be 1, if the system is divided into two oscillations, the dimension is to be 2, and if the system is in a Khaos like condition, the dimension is to be more than 2. By this constitution, unstableness in output can thereby be appropriately monitored.

Abstract: PURPOSE:To execute exact charge collection by transferring old time data to an auxiliary clock before an internal clock is updated, reading an ending time from the auxiliary clock when usage is started before the internal clock is updated, calculating a use time and calculating the exact used time. CONSTITUTION:When a call is started, a processor 1 of a private exchange reads a time tA from an internal timer 2 as call processing and houses the time to a main memory 4.

Title: Manufacture of organic el element and organic el element
Inventor: MORI MASAMI
IPC: H05B33/26
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an organic EL element having an electrode excellent in physical properties of a film without physically damaging an element constituting film by an atom sputtered at film forming time of the electrode by forming the electrode as a film by a sputtering method by which the product of film forming gas pressure and an inter base board target distance falls within a specific range. SOLUTION: As a condition where a film is formed by sputtering on an organic EL structure body formed on a base board, the product of film forming gas pressure and an inter-base board target distance is set to a range of 20 to 65 Pa.cm. Though a sputtered atom loses kinetic energy in the middle of reaching the base board, its rate depends on both the film forming gas pressure and the inter-base board target distance. A film forming condition where kinetic energy of the sputtered atom is lost by scattering by sputtering gas and becomes the vicinity of just zero is good. That is, this film forming condition is 20 to 65 Pa.cm. Therefore, initial light emitting luminance is enhanced, half value time of luminance is also lengthened, generation of a dark spot in the initial stage and after driving is reduced, and a light emitting characteristic can be improved.
