Title: Fixed current source circuit with variable temperature compensation
Inventor: KEVIN PAUL DEMSKY
IPC: G05F3/16
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To compensate a temperature effect by selectively combining the current from a current sector connected with a current source having a positive temperature compensation coefficient and the current from a current sector connected with a current source having a negative temperature compensation coefficient. SOLUTION: Current from a positive temperature coefficient current source 330 is divided from a current mirror P2 by a first current sector between P5 and P6. When a reference voltage 370 is higher than a variable control voltage 310, current from the P6 is made higher than the current output of the grounded P5. In the same way, current from a negative temperature coefficient current source 320 is subjected to mirroring on a current mirror P3, and equalized by a second current sensor between P7 and P8. When the reference voltage 370 is higher than the variable control voltage 310, much more current is allowed to flow through the P8, and grounded. In the connection of the current from the P6 and P7, an output from the P6 is made higher than the output of the P7, and therefore output current 340 has a positive temperature coefficient.  When the variable control voltage 310 is higher than the reference voltage 370, the output current 340 has a negative temperature coefficient.

Title: Circuit breaker
Inventor: MORIAI HIROSHI
IPC: H01H83/02
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To compactly mount a leakage signal output contact in a circuit breaker having leakage display function. SOLUTION: In a circuit breaker projecting a leakage indicating bar 13 by a leakage detecting mechanism 9 at the time of occurrence of leakage, a switching operation element 23c of a leakage signal output contact 25 is integrally formed with the bar 23.
