A specific-equipment management system is equipped with a question generator, a display unit and an input unit and manages a water heater. The water heater is equipment that requires human operation in the vicinity when used. The question generator generates question information. The question information is information regarding a question for specifying a specific-error. The 'specific-error' is an error regarding the water heater and includes an error regarding the human operation. The display unit displays the question information. Response information is then inputted to the input unit by the user based on the question information displayed at the display unit. The response information is information regarding the state of the water heater or the state of the human operation. The question generator generates next question information based on the response information. The display unit then displays the next question information.

Specific-equipment management system, specific-equipment management program, and specific-equipment management method in which question information regarding a question estimating a specific-error cause is generated, the error regarding the specific-equipment and including human error regarding the human operation

The present invention is intended to efficiently implement noise countermeasures for a semiconductor circuit board and for a semiconductor circuit. The present invention is constituted by a control substrate, and a semiconductor circuit connected to the control substrate. The semiconductor circuit includes a substrate, an integrated circuit group, and a noise countermeasure, and is separated from the control substrate. The integrated circuit group includes an integrated circuit as a noise source. The substrate has a stacked multilayer structure, and shifts the frequency of a noise generated by the integrated circuit group to the high frequency side. The noise countermeasure is connected between the integrated circuit group and the control substrate. The noise countermeasure is a filter for attenuating the high frequency of a noise.
