Abstract
Abstract The circuit and method of connecting a J-K flip-flop so that it will operate as a one-shot multivibrator comprising establishing a ''''set'''' input at a logic 0 and an appropriate J or K input at a logic 1 for momentary operation in response to a clock input.

Claim 2
Dependent Claim
79 words
Apparatus of the class described comprising in combination: J-K flip-flop means including set, clock and K inputs and a false output; means for continuously supplying a logic zero connected to said set input; means for continuously supplying a logic one connected to said K input; means for supplying a clock signal connected to said clock input; and output means connected to said false output for receiving therefrom a pulse for each clock signal applied to said clock signal input.
Claim 3
Dependent Claim
24 words
Apparatus as claimed in claim 1 wherein said J-K flip-flop includes a true output connected for supplying said logIc one to said K input.
Claim 4
Dependent Claim
26 words
Apparatus as claimed in claim 1 wherein said J input is connected to said set input and the means for supplying a logic zero is ground.
Claim 5
Independent Claim
52 words
The method of converting a J-K flip-flop to a one-shot multivibrator comprising the steps of: grounding the set input; connecting a logic one to the K input; and supplying a clock signal to the clock input of the J-K flip-flop whereby a short duration pulse is obtained from the false output thereof.
Claim 6
Independent Claim
52 words
The method of converting a J-K flip-flop to a one-shot multivibrator comprising the steps of: grounding the set input; connecting a logic one to the K input; and supplying a clock signal to the clock input of the J-K flip-flop whereby a short duration pulse is obtained from the false output thereof.
Claim 7
Dependent Claim
75 words
One-shot multivibrator apparatus comprising, in combination: J-K flip-flop means including J, K, C, and S inputs, and Q and Q outputs; means connecting said Q, J, and K terminals together; means connecting said S terminal means to a logic zero; and means for supplying a clock input to said C terminal means whereby a single output pulse is obtained from the Q output upon each application of a clock signal to said C terminal means.
Claim 8
Dependent Claim
75 words
One-shot multivibrator apparatus comprising, in combination: J-K flip-flop means including J, K, C, and S inputs, and Q and Q outputs; means connecting said Q, J, and K terminals together; means connecting said S terminal means to a logic zero; and means for supplying a clock input to said C terminal means whereby a single output pulse is obtained from the Q output upon each application of a clock signal to said C terminal means.
Claim 9
Dependent Claim
79 words
One-shot multivibrator means comprising, in combination: J-K flip-flop means including S and J terminal means connected to a logic zero signal source, a Q terminal means connected to a K input and further including C and Q terminal means; means for supplying a negative-going clock signal to said C terminal means; and output means for supplying a short duration output signal from said Q terminal means upon each negative-going occurrence of said clock signal to said C terminal means.
Claim 10
Dependent Claim
79 words
One-shot multivibrator means comprising, in combination: J-K flip-flop means including S and J terminal means connected to a logic zero signal source, a Q terminal means connected to a K input and further including C and Q terminal means; means for supplying a negative-going clock signal to said C terminal means; and output means for supplying a short duration output signal from said Q terminal means upon each negative-going occurrence of said clock signal to said C terminal means.
Claim 11
Dependent Claim
91 words
One-shot multivibrator apparatus comprising, in combination: J-K flip-flop means including ''''set'''' J, K, clock, and at least one output terminal means; means for continuously supplying a logic one to one of said J and K terminal means; means for continuously supplying a logic zero to said ''''set'''' input means; and means for supplying a clock input signal to said clock input means whereby said at least one output terminal means momentarily attempts to change in potential but is prevented from doing so by the logic value supplied to said ''''set'''' input.
Claim 12
Dependent Claim
91 words
One-shot multivibrator apparatus comprising, in combination: J-K flip-flop means including ''''set'''' J, K, clock, and at least one output terminal means; means for continuously supplying a logic one to one of said J and K terminal means; means for continuously supplying a logic zero to said ''''set'''' input means; and means for supplying a clock input signal to said clock input means whereby said at least one output terminal means momentarily attempts to change in potential but is prevented from doing so by the logic value supplied to said ''''set'''' input.
Claim 13
Independent Claim
88 words
The method of converting a J-K flip-flop comprising J and K input means, ''''set'''' terminal means, output means, and clock means to a one-shot multivibrator comprising the steps of: continuously supplying a first logic signal to the set means to prevent permanent change of potential at said output means; continuously supplying a second logic signal to one of said J and K inputs; and supplying a clock signal to the clock input of the J-K flip-flop whereby a short duration pulse is obtained from said output means thereof.
Claim 14
Independent Claim
88 words
