Abstract: A control device of a semiconductor manufacturing apparatus includes a processor and a memory connected to the processor and storing instructions executable by the processor. The instructions collect a sound of processing a substrate by the semiconductor manufacturing apparatus. The instructions calculate a difference of a power spectrum of the processing sound between a first point of time and a second point of time. The instructions determine a change point of processing of the substrate based on the difference.

Abstract: A jet propulsion boat includes a boat body, a handle bar, an engine, a jet propulsion mechanism, a reverse gate, and a shift operating device. The handle bar is attached to the boat body. The handle bar extends in a width direction of the boat body. The engine is housed in the boat body. The jet propulsion mechanism is configured to generate a propulsion power from a drive power of the engine. The reverse gate is located rearward of the jet propulsion mechanism. The reverse gate is configured to move so as to change a direction of a jet flow from the jet propulsion mechanism. The shift operating device is rotatably attached to the handle bar about a shaft center parallel or substantially parallel to a center line of the handle bar. The shift operating device is configured to rotate so as to switch a position of the reverse gate.
