Title: Method and apparatus for estimating and displaying remaining life of member
Inventor: SAKURAI SHIGEO
IPC: G01N29/04
Filed: 1989-09-13
Abstract: PURPOSE:To achieve higher reliability and safety by measuring limit damage length and actual length of a flaw. CONSTITUTION:Degree of damage is detected as length (a) of a flaw with a detector 5. The length ai of a damage is estimated at the subsequent operation, for example, after 6 months from the length (a) detected. The subsequent formula is determined from a detection or calculation value of the length of the flaw at present. log (a)=C(t/ tr), wherein C represents constant determined by grain size, tr breaking life, (t) elapsed time for member under a high temperature. On the other hand, a hysteresis loop area A is detected with an aging detector 10 to calculate a limit damage length acr for the member from the area A. A forecast limit damage length acri after 6 months is forecast by estimating a progress of the limit damage length acr. The lengths ai and acri are compared and when the estimated damage length ai does not reach the forecast limit damage length acri, after the estimating period, the life of the member does not yet expire even after the 6 months. Hence, the extra life of the member is diagnosed. In the diagnosis of the residual life, the life is determined as time until it reaches intersection between extension of the estimated damage length ai and extension of the forecast limit damage value acri as 100% of life.

Title: Power-factor control circuit
Inventor: JIEFU DABURIYUU HOORU
IPC: H02M1/00
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To provide an integrated power factor control circuit by which the sinusoidal waveform of an average AC line current is maintained and the phase of the average AC line current is maintained so as to be identical in the phase of a line voltage. SOLUTION: An integrated power factor control circuit 12 gives a boosted DC voltage which is larger than the amplitude of a line voltage. A transconductance amplifier supplies boosted source and sink currents, when an output voltage is significantly shifted from regulation. The source and sink currents of the transconductance amplifier improve the response speed ability of a voltage control loop to the variation of the output voltage and reduce the time required for the generation of an adjusted voltage at the time of a start-up. A comparator 17 supplies a boosted current at the start-up time and detects a no-load state during normal operation. The comparator 17 detects the no-load state, stops the switching operation and avoids the further output charge, before an out-of-range state is produced.

Abstract: PROBLEM TO BE SOLVED: To detect a call originator number even halfway and to quickly identify whether or not the call originator is the specified one by permitting a detecting means to have synchronization by means of the change of a bit which is added in a call originator number and reading the call originator number. SOLUTION: When a pole reverse signal which is transmitted from an exchange to a terminal side system 4 by starting a center side system 7 is detected by a pole reverse detecting part 13, a control part 19 sets the interruption of an input port in the both edges of a bit change point. The change point A of a call originator number signal is detected by interruption. A half bit time is set in a timer with the point A as a synchronization point. At time-up in the timer, the bit is read with the point B as a bit center. The timer in the control part 19 is cleared from the point B so as to set one bit time and the bit of the point C is read by sampling at every time-up in the timer. Detected bit data is stored in RAM in the control part 19. A processing is completed when the carrier of an FSK signal used in the modulation of the call originator number signal is exhausted.
