Patent JP-H05327367-A (JP)
Title: Current/voltage conversion circuit
Inventor: MURAKAMI HIROSHI
IPC: H03F3/34
Filed: 1992-05-26
Abstract: PURPOSE:To enlarge the range of current/voltage conversion by providing an analog switch so as to short-circuit one part of plural serially connected current/ voltage conversion elements and controlling the opening/closing of the analog switch with the output of a comparator to invert operations corresponding to an input current. CONSTITUTION:When the input current is small, a comparator 9 is not operated since the output value of a current/voltage converting amplifier 1 is larger than the reference voltage value of the comparator 9, and an analog switch 8 is set in the opened state. Therefore, the two steps of diodes 4 and 5 are operated as the current/voltage conversion elements. When the input current gets larger than a certain value, the comparator 9 inverts the operations since the output value of the converting amplifier 1 gets smaller than the reference voltage value of the comparator 9, and the switch 8 is controlled. As a result, the diode 5 is short-circuited, and only the diode 4 performs the operation of current/voltage conversion. Thus, the range of current/voltage conversion can be enlarged by providing the plural conversion elements and changing them on multiple stages corresponding to the input current.

Filed: 1989-05-30
Abstract: PURPOSE:To eliminate the need for logical matching or address grouping of a signal in response to each load even when loads with different fail safe state exist by using one bit in two bits of control signal in response to each load so as to control the system. CONSTITUTION:An ON signal and an OFF signal per one circuit of terminal control output are constituted in 2-bit and the a-bit 0 and b-bit 1 of the 2-bit signal represent an ON signal and the a-bit 1 and b-bit 0 of the 2-bit signal represent an OFF signal conversely. Then both the a-bit and b-bit are set to 0 in the fail safe state and a terminal equipment 3 references the a-bit in this case to follow the command and a terminal equipment 6 reference the b-bit to follow the command. Then a lighting load 4 is lighted in the fail safe state and a power load 7 is deenergized. Thus, even when loads with different fail safe state exist in mixture, it is not required for the CPU 1 to match the logic of the signal in response to each load for signal transmission or grouping of a terminal equipment address in response to each load.
