摘要： PROBLEM TO BE SOLVED: To be immune to noise, to transmit sound wave to a distance, to prevent attenuation of the waveform, and to accurately measure the pipe length.
SOLUTION: In a state where a measuring mechanism 1 having a movable mechanism section 11 and a measuring pipe 12 is connected to a pipe 3, a sound reception signal sent from a microphone 103 arranged so that howling occurs in a measuring pipe is received from a speaker 102. Until sound waves of a large amplitude by the speaker 102 and microphone 103 occur in the pipe 3, a driving section 104 is controlled, and a stationary wave spectrum is detected, they are simultaneously adjusted while the interval between the speaker 102 and microphone 103 is kept constant. Using temperature data about the pipe and peak frequency of stationary wave, the pipe length is calculated by a control section 21 of a measuring device 2 based on a predetermined expression.

摘要： PROBLEM TO BE SOLVED: To be immune to noise, to transmit sound wave to a distance, to prevent attenuation of the waveform, and to accurately measure the pipe length.
SOLUTION: In a state where a measuring mechanism 1 having a measuring part 11 and a measuring pipe 12 is connected to a pipe 3, a sound reception signal emitted from a microphone 103 arranged so that howling occurs in the measuring pipe is received from a speaker 102. Until a sound wave having a large amplitude by a speaker 102 and the microphone 103 occurs in the pipe 3 and a standing wave vector is detected, the frequency of a signal generated from a signal generation part 104 is changed and controlled, By using temperature data in the pipe and the peak frequency of the standing wave at that time, the pipe length is calculated by a control part 21 of a measuring device 2 based on a predetermined expression.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method for remotely monitoring a bottom face of a vehicle without stopping the traveling vehicle. SOLUTION: A digital camera 3 is equipped with a fish-eye lens and installed on a road surface 2. A vehicle speed sensor 5 gives a vehicle speed signal (a) obtained by detecting a traveling speed of the vehicle 1 to a vehicle/distance conversion circuit 7b. The vehicle speed/distance conversion circuit 7b converts the inputted travel speed into a time required for traveling a predetermined distance (for example, 1 m) and gives the converted time signal b to an imaging control circuit 7a. The imaging control circuit 7a instructs the digital camera 3 to take a picture intermittently at instructed intervals. Since an image signal f outputted from the digital camera 3 has a spherical aberration specific to the fish-eye lens, the spherical aberration is corrected by an image processing circuit 7c, and a single image is obtained when a plurality of images taken for the respective predetermined distances are connected mutually.
