Title: Frequency discrimination
Inventor: TAENAI SHIGERU
IPC: G01R23/15
Filed: 1980-08-19
Abstract: PURPOSE:To enable the judgement to be performed without the effect of the duty cycle of an external clock, by synchronizing two pulses with different frequencies, by resetting an FF which is set after the specified time, and judging whether the FF is to be set by the pulses is set or not. CONSTITUTION:When an external input I1 is inputted, FFs F1, F6, F7 are set, F2 is set by setting F1 and a counter C1 starts counting. After the time [(1/f1)-[(f1- f2)/2f1f2]] from the starting of the counter C1, the counter C1 stops counting, F4 is set, and F2, F6, and F7 are reset. Then F3 is set, and a counter C2 starts counting. After the time (f1-f2)/f1,f2, the counter C2 is stopped, F4 is set, and F3 and F7 are reset. Thus, the FFs are sequentially reset. Either an output O1 or an output O2 is outputted only when either F8 or F9 is set. In the case of O1, frequency f1 is identified, and in the case of O2 frequency f2 is identified.

Title: Switching regulator control circuit
Inventor: SUDO MINORU
IPC: G05F1/10
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To operate SW regulators without malfunctioning by adding a low-pass filter to the output of the bleeder resistors in an SW regulator to prevent high- frequency noise produced by another SW regulator from entering the bleeder resistors. SOLUTION: A low-pass filter(LPF) 20 is added between the connecting point of bleeder resistors 11 and 12 and the input of an error amplifier 13. When SW regulators are simultaneously operated, the voltage Va at the connecting point between the bleeder resistors 11 and 12 is caused to fluctuate by switching noise from another SW regulator. Letting the voltage at the connecting point between the bleeder resistors 11 and 12, or the input of LPF 20, be Va and the voltage at the input of the error amplifier 13, or the output of LPF 20, be Vb, the voltage Vb is not caused to fluctuate by noise even if the noise is superposed on the bleeder resistors 11 and 12,. As a result, the input of the error amplifier becomes constant and malfunctions of the SW regulators are prevented.
