Title: Measurement of tank content capacity
Inventor: HAYASHI YUTAKA
IPC: G01F23/296
Filed: 1981-09-17
Abstract: PURPOSE:To detect easily and with high accuracy the position and capacity of the content in a tank by issuing pulses onto the upper face of a stored material from an ultrasonic wave generator, infrared light or a laser oscillator that is provided at the upper section of the tank and detecting the time which the pulses take from being issued to returning by reflection at the upper face of the stored material. CONSTITUTION:Ultrasonic wave sending and receiving devices 2a and 2b that are located at the top of a tank 1 sends ultrasonic pulses to the upper surface section 4 of the content (for example rice grains) of the tank 1, and its reflection wave 8 is received. The received waves are sent to a recorder 7 through a receiver 6b. From the time from sending the ultrasonic wave to receiving the reflection wave 8 the position of the upper surface section 4 is detected to know the volume of the content in the tank 1. With this arrangement the position of the upper surface 4 of the content 3 and its volume can be easily and exactly measured.

Filed: 1978-11-25
Abstract: PURPOSE: To silence noise, by providing inside of a silencer with a soft and elastic thin-film container filled with a low-sound-impedance media, and reversing sonic phase reflecting on the surface of the container.  
     CONSTITUTION: A soft-light-elastic thin-film container 10, which is filled with a media 9 whose sound impedance is smaller than a flow-in and flow-out fluid body, is provided in the neighborhood of a flow-out tube 6. Because of this mechanism, sound wave conducting in a fluid body from the flow-out tube 5 reflects upon an interface 10 between the fluid body and the low-sound-impedance media filled in the container, and since sonic phase is reversed at this time, the sound energy going out from the other flow-out tube 6 is diminished.

Abstract: PURPOSE: To obtain an optical alignment adjusting apparatus by which the alignment of an optical system can be adjusted with good accuracy without being affected by the change with time of an angle error and by an identification error by updating angle correction amount on the basis of its detection whenever an angle error amount is detected. CONSTITUTION: A laser beam from a light source 11 is projected to a scanning mirror 10 via a fixed mirror 12 and a beam splitter 13. Interference fringes are generated by an optical path difference generated at a time when the scanning mirror 10 is driven in the direction of normal line by a driving mechanism 1, and the interference fringes are inputted to a detector 14. The detector 14 computes the alignment error of an optical system on the basis of the interference fringes, a computed result is outputted to a controller 20 as a fine alignment error signal, and the controller 20 performs a closed-loop control operation so as to make the error zero. In addition, according to the driving distance of scanning mirror 10, an angle correction signal is inputted to the controller 20 from an angle error database 30, and an angle error is corrected by an open loop.  In addition, whenever the fine alignment error signal is detected, the database 30 is updated by an angle-error-database update logic 40.
