Title: Fault detector
Inventor: NAGAOKA SHINJIROU
IPC: G06F11/22
Filed: 1984-03-01
Abstract: PURPOSE:To decide quickly the propriety of a device to be tested at noise test by outputting and storing error state information when a voltage to be tested exceeds a reference voltage and further displaying it so as to erase the storage information at a prescribed time thereby applying complete shield to all the circuits. CONSTITUTION:A reference voltage circuit 2 outputs a reference voltage 102, which is a permissible maximum instantaneous value of a voltage 100 to be tested and set to an optional value in response to a device to be tested. A comparator circuit 1 compares the voltage 100 to be tested with the reference voltage 102 and outputs a fault state signal 101 when the voltage 100 to be tested exceeds the reference voltage 102. A storage section 4 stores the error state information represented by the fault state signal 101. A display section 5 displays the fault state information so as to inform it and a reset circuit 3 resets the storage section 4 after a prescribed time. Thus, the display of the display section 5 is revised at each time and the operator supervises continuously the voltage 100 to be tested. Moreover, the entire console is made of an enclosed metal box and complete shield is applied to components in the inside.

Abstract: PURPOSE:To propagate light in only either of two orthogonal polarization modes by making an inside clad which surrounds a core smaller in refractive index than the core and making an outside clad larger in the refractive index than the inside clad. CONSTITUTION:A single-mode fiber has the inside and outside clads 2 and 3 and strain inducing members 5 around the core 1.
