DETONATING AND ELEMENT Russian patent published in 1999 - IPC

FIELD: logic units realizing logical operations with the aid of blast, in particular, detonating AND elements. SUBSTANCE: detonating AND element uses blasting circuits, blastic circuit branching joints, and blasting gates, the first of which is located in the first blasting circuit between the first blasting branching connected to the first input of the detonating AND element and its output; the second blasting gate is positioned in the second blasting circuit between the first blasting branching and the control input of the first blasting gate. The control input of the second blasting gate is connected via the third blasting circuit to the second input of the detonating AND element, it comprises an additional branching joint in the third blasting circuit connected via an additional blasting circuit to the control input of the first blasting gate. To expand the field of application of the detonating AND element due to control of resolving time τ_p, the additional blasting circuit uses a delay unit of blasting signal propagation time. This delay unit may be cut in between the branching joint of the first and second blasting circuits and the blasting gates of the respective circuits, or in the blasting circuit between the first input of the AND element and the branching joint of the first and second blasting circuits, or in the additional blasting circuit and in the blasting circuit between the branching joint of the blasting circuits actuated from the second input of the blasting circuit, or in the blasting circuit between the second input of the AND element and the branching joint of the blasting circuits actuated from the second input of the AND element. EFFECT: enhanced reliability of functioning of the AND element due to reduction of the number of blasting gates and reduction of probability of random actuation of the element. 6 cl, 10 dwg
