摘要： An improved flip-flop circuit is provided which prevents the occurrence of soft errors due to .alpha. rays and the like emitted from a trace amount of radioactive materials contained in a semiconductor package material. The flip-flop circuit has a first logic circuit which holds data and produces a first logic signal and a second logic circuit which produces a second logic signal. A logic gate receives the first and second logic signals that are produced from the first and second logic circuits and which have the same logic level. The output of the logic gate is input to the first logic circuit through a feedback loop which is provided between the output and the input of the first logic circuit and which includes the logic gate. According to the circuit construction of the present invention, a flip-flop circuit can be accomplished which is resistant to the radioactive rays such as .alpha. rays and does not cause soft errors.

摘要： A transistor circuit of this invention comprises a first transistor for receiving a first bias at its base, resistor means connected to the collector of the first transistor and clamp means connected to the junction between the first transistor and the resistor means, and obtains an output from a terminal of the resistor on the opposite to its junction with the first transistor. When a noise current due to .alpha. rays develops in the first transistor and the output is lowered, the clamp means operates in such a manner that the current flows through the clamp means and prevents the change of the output. The transistor circuit of this invention is connected to a resistor or a transistor and operates as a constant current circuit for supplying a current to the resistor or the transistor so that the current flowing therethrough becomes constant. For example, it is used as a constant current source of an emitter follower to constitute a level shift circuit. It is disposed in a feedback part and used as a constant current source in a logic circuit comprising a logic part consisting of a differential transistor circuit and the feedback part for negatively feeding back the in-phase output of the differential transistor circuit.
