Title: Ultrasonic sensor
Inventor: NAGURA NARIMASU
IPC: G01S7/521
Filed: 1990-09-17
Abstract: PURPOSE:To enable presence or absence of an object to be detected which is located at a short distance to be detected stably and positively by forming a surface of an ultrasonic element in recessed shape so that ultrasonic waves can be focused at a specified distance. CONSTITUTION:A sensor 1 for short distance has an ultrasonic oscillator 3, thus enabling ultrasonic wave to be transmitted to an object to be detected k and reflected ultrasonic waves to be received for detecting presence or absence of the object (k) to be detected. At this time, a surface 3a which is opposite to the object (k) to be detected of the oscillator 3 is formed in recessed shape, thus enabling ultrasonic wave to be always focused at a specified distance. Therefore, even if a high-order reflection wave is received, attenuation and diffusion of the ultrasonic waves on reflection can be prevented. If the object (k) to be detected is located at a distance which is further than the focusing point, it is diffused on reflection and wave received by the sensor 1 becomes small, thus enabling detection distance to be specified easily. Therefore, it becomes possible to achieve a stable detection without being affected by a background object.

Abstract: PURPOSE:To measure weight highly accurately at low cost by means of a small sized weight sensor by arranging a member to absorb shrinkage strain in the perpendicular direction to excitation between a piezoelectric element to excite an object to be measured and a piezoelectric element to detect reaction force from the object to be measured generated by the excitation. CONSTITUTION:An object 15 to be measured is excited at a constant period by means of the first piezoelectric element 12, and reaction force from the object 15 to be measured generated by this excitation is detected by means of the second piezoelectric element 14. At this time, piezoelectric strain generated in the perpendicular direction to the exciting direction of the piezoelectric element 12 is absorbed by a plate member 13 as a strain absorbing means, and is not propagated to the piezoelectric element 14, so that the piezoelectric element 14 outputs electric power proportional only to the strain caused by the reaction force from the object 15 to be measured. Thereby, weight of the object 15 to be measured can be measured highly accurately.
