Claims

[Scope of utility model registration request]

In an ultrasonic detector that transmits an ultrasonic pulse signal at a fixed or arbitrary period and detects an object by the ultrasonic reflected wave from the reflected object, a first time set after a certain period of time after the ultrasonic pulse is transmitted. a first gate circuit that allows reflected waves to pass only within the mountain; and a second gate circuit that is set after the first time width has elapsed.
a second gate circuit that allows the reflected wave to pass only within the peak for a time period of a first output circuit and a second output circuit that respectively output the outputs of the memory circuit and the second memory circuit, and the first memory circuit is provided between the second memory circuit and the second output circuit. An ultrasonic detector comprising an output inhibit gate circuit that stops the output of a second output circuit when the output of the circuit is present.
