Title: Light redundancy switching method for light wavelength multiple system
Inventor: KUBO KAZUO
IPC: H04B10/03
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To suppress influences upon a transmission feature of increase/decrease of the number of wavelengths accompanying the switching of redundancy system by making a gain of a light amplifying repeater smaller while an active channel of an active system which is faulted is connected to a standby system light terminal station device at the time of faulty of the active system. SOLUTION: When a light level of a light wavelength λ1 is lowered or enters a quenching state due to failure, the light wavelengths other than λ1 are excessively amplified in light outputs of light amplifying repeaters 29a to 29n, transmission features of λ2 to λ5 are deteriorated by being shifted from a state of line design and a normal communication state cannot be confirmed. Thus, in this light redundancy switching method, it is controlled so that gains of the light amplifying repeaters 29a to 29n are made smaller and the transmission features of the λ2 to λ5 are maintained in a normal state.  In this way, since the gains of the light amplifying repeaters 29a to 29n are made smaller at the time of faulty of the active system, normality of a standby system can be normally confirmed and, at the same time, influences upon the transmission features by reduction of the number of wavelengths for emitting light can be suppressed.

Filed: 1987-06-03
Abstract: PURPOSE:To surely detect the abnormality of a bearing even under the considerable noisy environment by detecting an acoustic emission from the bearing, and comparing the number of values every period in which a detected value exceeds a threshold value. CONSTITUTION:An acoustic emission (AE) generated by a bearing, etc. is detected by a sensor 1, the noise is eliminated by allowing an AE signal of 100kHz-500kHz to pass through a BPF 3, thereafter, said signal is brought to an envelope detection by an envelope detecting circuit 5. The AE signal which is detected is compared with a threshold value by a comparator 6, and when it has exceeded the threshold value, a pulse is outputted to a computer 7. The computer 7 calculates a period of the signal from the comparator, based on the speed of revolution of the bearing per unit time from a rotation sensor 8, and calculates the frequency of the number of times of generation of every signal generating period. Also, when the frequency exceeds the threshold level, it is decided to be a damage of the bearing and an alarm is outputted.

Title: Sound recording method with prevention from sound rerecording
Inventor: OKANO KAZUO
IPC: G11B20/00
Filed: 1982-08-14
Abstract: PURPOSE:To prevent dubbing from a sound recording tape by recording an objective signal together with an AC signal of such frequency that it interferes with the bias alternating current of the sound recording head of a sound recorder. CONSTITUTION:This method prevents a record or magnetic tape where a signal is recorded from being dubbed. When the recorded is manufactured, the objective signal and another AC signal are recorded together and this AC signal has such a frequency that it interferes with the bias alternating current of the sound recording head of the sound recorder. If this record is dubbed to a magnetic tape, the bias alternating current of the sound recording head and the AC signal interfere with each other when recorded on the magnetic tape, so the purpose of the dubbing is not attained. However, when the recording is played as it is, there is not caused any trouble.
