IPC: G01J1/42
Filed: 1981-12-31
Abstract: PURPOSE:To obtain a flame detection circuit free of occurrence of hazardous state, e.g., fire, etc., by using a system in which alarm is always sento out even when a flame eye becomes out of order. CONSTITUTION:By using an arithmetic amplifier 30 of the same input voltage characteristics with transfer characteristic as a comparator in which signal from a flame eye 12 is compared with reference voltage and by the output an ignition control relay 13 is ON-OFF controlled, when the signal from the flame eye is below the transfer level of the arithmetic amplifier 30, output similar to the dark state of the flame eye is taken out of the arithmetic amplifier to put the ignition control relay to ON-operation. Thus, since alarm operation treatment can be finally made in the combustion controller even when the flame eye  is broken down by short-circuit, a flame detection circuit having a very high safety, without defects, e.g., nonstop release of fuel, etc., can be obtained.

IPC: G01D5/245
Filed: 1992-07-17
Abstract: PURPOSE:To enable the detecting of the omission of a pulse instantaneously and accurately with a simple hardware detection circuit by adding a pulse calculated value of one phase to a complement of a pulse calculated value of the other phase. CONSTITUTION:Among a counter 1 for counting a pulse of a phase A and a counter 2 for counting a pulse of a phase B of a pulse encoder, a complement of an output value of the counter 2 is taken with an inversion circuit 3 to add the output value to an output value of the counter 1 with an adder 4. In the normal operation, a value of the adder 4 is any of 1111b, 1110b and 0000b. But when an pulse omission occurs in a detection pulse, lower two bits give 01b. When the outputs of terminals S1 and S0 give 01b, an abnormality detection circuit 5 outputs a LOW signal, namely, an abnormality detection signal. Thus, the omission of any pulse can be detected instantaneously and accurately with a simple hardware detection circuit and application for a machine tool or a robot controller achieves a prevention of work or a machine or higher safety or higher controlling accuracy.

IPC: H02J9/06
Filed: 1984-10-12
Abstract: PURPOSE:To perform secure switching to a backup power source by providing a switching element which turns off when a power source becomes down between a load and the power source. CONSTITUTION:When the power source A is connected by turning on a switch 2, the comparison voltage of the 1st comparing circuit 4 is boosted by the series circuit of resistances R3 and R4 above a reference voltage and the output of the comparing circuit 4 is inverted to a level '0'. Therefore, a transistor Tr1 turns on and the voltage of the power source A is supplied to the load 1 from an output terminal 7. Then, when the power source A becomes down owing to a power failure, etc., the Tr1 turns off, so the potential VS at the output terminal 7 drops and the base current of a transistor switch Tr2 is controllable when VS=VregX(R5+R6)/R6. Therefore, said VS is supplied continuously to the load 1 from the output terminal 1.
