Abstract: Each energy value calculation circuit calculates an energy value, based on a sum total of values obtained by multiplying state values of a plurality of second neurons coupled with a first neuron by corresponding weighting values indicating coupling strengths, and updates the energy value, based on identification information of an updated neuron whose state is updated among the plurality of second neurons and a state value of the updated neuron. Each state transition determination circuit outputs, based on a second energy value and a noise value, a determination signal indicating a determination result of whether a change in a state value of the first neuron is possible. An updated neuron selection circuit selects, based on received determination signals, a first neuron a change in whose state value is possible and outputs identification information of the selected first neuron as identification information of the updated neuron.

Abstract: A retainer is equipped with a regulation segment, which regulates the position of an O-ring placed in an insertion hole, and a prevention segment, which engages with a spool of a pipe and prevents the pipe from being removed from the insertion hole. Moreover, by moving the retainer toward the minus side in the Y direction and attaching it to an attachment segment, the retainer becomes sandwiched between an opposing wall portion and a tube segment in the X direction. Because of this, the number of parts can be reduced and the retainer that regulates the position of the O-ring can be prevented from being moved in the X direction by the pressure of fluid flowing inside the pipe connector in the X direction.
