Title: Reactive power compensating device
Inventor: NISHIKAWA TADASHI
IPC: H02J3/18
Filed: 1986-06-25
Abstract: PURPOSE:To prevent a thyristor from breaking down owing to incomplete gate pulses by inhibiting the ignition pulse of the thyristor from turning off almost at the voltage peak value of a power system to which a reactive power compensating device is connected. CONSTITUTION:The voltage signal of a power source side is detected by a current transformer and inputted to an absolute value circuit 102 through a 90 deg. phase shifting circuit 101. Then, a level detecting circuit 103 detects its level and outputs a signal of '1' to an OR circuit 104 when the detected level is lower than a specific level. If a capacitor turn-off command is generated almost at the peak of a source voltage, an FF 111 is reset forcibly and its output Q becomes zero. The signal (a) of an AND circuit 104, however, is one, so the output of an OR circuit 105 becomes one and switching is not performed almost at the peak of the source voltage eventually and postponed.

Title: Distorsion detector for multi-channel record reproducer
Inventor: SUZUKI FUJIO
IPC: H03D3/00
Filed: 1977-12-12
Abstract: PURPOSE:To facilitate discrimination between the musical sounds and the distorsion by separately detecting a relatively light distorsion and such distorsion as is followed by abnormal sounds to deteriorate the musical quality. CONSTITUTION:In case a terminal 18 is supplied with such signals having angles to be modulated as give normally modulated signals, there is no output generated from a synchronous detector 25. When the terminal 18 is supplied with the signals including a relatively light distorsion, the output voltage of the deector 25 is fed to BPFs 27 and 28. The BPF 27 generates vertically symmetrical signals having a high level as the distorsion detecting signals whereas the BPF 28 generates the distorsion detecting signals having a low level. It is possible to accomplish the detection while discriminating the cases, in which the modulated signals are normal, in which the modulated signals have a light distorsion, and in which abnormal sounds are generated in the modulated signals.

Title: Period-measuring circuit
Inventor: ISODA KAZUNARI
IPC: G01R23/10
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To reduce the load of a CPU by arbitrarily specifying a measurement target frequency and omitting the measurement of a pulse signal that is shorter than a measurement range due to, for example, noise from being selected. SOLUTION: A frequency value for making valid the output of an edge detection circuit 209 being inputted to a filter circuit 260 is set to a compare register 250. The edge detection circuit 209 monitors an input signal S11 and detects whether a pulse signal with a predetermined shape has been inputted or not. When it is confirmed that a pulse signal with a predetermined shape is inputted, a trigger signal is outputted to a filter circuit 260 and a compare register 250. The compare register 250 compares the frequency of the trigger signal with a set value and outputs a signal S82 that indicates that the trigger signal is invalid when the frequency is higher than the set value.  Even if a pulse signal that is shorter than a measurement range is inputted to an external trigger terminal 20 due to, for example, noise, no signal is outputted to a capture register 204 and no periodical measurement treatment is made, thus unneeded load is not applied to a CPU.
