Title: Flow velocity measuring device by ultrasonic wave
Inventor: KOBORI YASUHIRO
IPC: G01P5/00
Filed: 1979-11-26
Abstract: PURPOSE:To get rid of a measuring error caused by a temperture, by constituting the device so that the measured value of the velocity of flow has no relation to the speed of sound. CONSTITUTION:The propagation time from transmission to receiving is measured and its measured value is processed. In this case, the voltage V which is proportional to the time (t) is generated, and when a clock of the frequency (f) which is proportional to this voltage V is made, (t), V and (f) are in direct proportion, and therefore the propagation time t1 in the forward direction and the propagation time t2 in the reverse direction become t1=l/(C+v)=V1=f1, and t2=l/(C-v)=V2= f2 (l is the distance between the cable transmitter and the receiver 3, 4, and C is the sound speed), respectively. Also, in case of reading out the clock of the frequency (f), when the time required for attaining to the optional number N prescribed in advance is measured, the measured value becomes T1=N/f1 and T2=N/f2. Accordingly, T1-T2=2Nv/l, therefore v=l(T1-T2)/2N, and the value of the velocity of flow (v) does not contain the speed of sound C and it is not affected by a temperature.

Abstract: PURPOSE:To prevent a detent member from moving unintentionally by furnishing the detent member at an opening near the tail of a housing, furnishing a cam mechanism in the neighborhood of this opening and at its mating surface of the detent member, which mechanism slides the detent member between two detaining positions. CONSTITUTION:A guide ridge 54 and a detent boss 53 on a detaining member 50 are located at guide groove 25a and guide notch 24 in a housing 10, and the detaining member 50 is fitted in an opening at the tail of the housing 10. When the detaining member 10 is intruded into the housing 10 until the front end face of a rear half high stepped part 51 of this detaining member 50 butts with the rear end face of the housing 10, the detent boss 53 is detained with the top of No.1 part 23a of a can groove 23, and there is no risk of the detaining member 50 moving to the final securing position. Then the detaining member 50 is depressed, and if further depressed, the detent boss 53 slides along the cam groove 23 from its No.1 part 23a to No.2 part 23b to come into detention with the tail end, and thus a female terminal 100 is hindered from moving backward of the housing 10. This prevents the detaining member from moving unintentionally.
