Title: Harmonic monitoring equipment
Inventor: KAMURA TSUTOMU
IPC: G01R23/20
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To make it sure to monitor a harmonic having possibility of damage generation, by obtaining and accumulating the content value or the content ratio of a specified order harmonic component of a signal to be measured, at a specified judgment time and interval, and generating an alarm when the judgment level is exceeded. SOLUTION: A signal to be measured is inputted in an input circuit 1. An I/O 5 outputs a timing signal, and delivers input signal data to a CPU 9. A memory card 7 sequentially stores measured each order harmonic data. The CPU 9 executes various kinds of processes on the basis of the program of an ROM 10, the setting condition of a key input part 13, etc. That is, the CPU 9 obtains repeatedly the content value or the content ratio of specific order harmonic component of the signal to be measured, at constant time intervals in a specific judgment time, and accumulates the frequency. When the content value or the content ratio of the previously determined cumulative frequency exceeds a previously determined judgment level, an alarm is generated.  Thereby generation of excessive harmonic level in a short time is surely detected without being affected by transient harmonic, and the alarm signal can be outputted.

Title: Battery type radio transmitter
Inventor: ISOBE YOICHI
IPC: H04B17/00
Filed: 1985-06-07
Abstract: PURPOSE:To simplify the circuit constitution and to improve the reliability by increasing a reference voltage for alarming discharge of a battery more than the sum of a minimum operating voltage of a transmission means and a voltage drop across the internal resistance of the battery at the transmission. CONSTITUTION:When a fault sensor S such as a fire sensor gives an output, an input supervisory means 1 controls a transmission means 2 to send a fault detection signal. When the voltage of the battery 3 reaches a reference voltage or below, a voltage detection circuit 4 gives an output to operate an informing means 5 for the information of the discharge of the battery. In this case, the reference voltage is selected larger than the sum of the minimum voltage required for the normal operation of the transmission means 2 and the voltage drop at the transmission across the internal resistance of the battery 3. Thus, the reliability of the battery type radio transmitter is improved with simple constitution.

IPC: H01L21/027
Filed: 1978-10-09
Abstract: PURPOSE: To increase the endurance of a mask by making a bright-and-dark pattern on a transparent substrate and stacking thin conductive transparent films thereon.  
     CONSTITUTION: A bright-and-dark pattern material 2 such as Cr and the like is selected and attached to glass 1, and a transparent conductive film 3 is attached.
