IPC: G01L13/06
Filed: 1990-05-25
Abstract: PURPOSE:To improve the balance to external vibration by stacking both-surface pressure reception type sensor elements on both end surfaces of a cylindrical holding material so that their characteristic surfaces are in the same direction. CONSTITUTION:Pressure to be measured is impressed from pressure intake holes 4 and 6. When pressure applied to the intake holes 4 and 6 is denoted as PA and PB respectively, the pressure PA and pressure PB are impressed to the surfaces A and B of a pressure sensor element 1 as shown by arrows and to the surfaces C and D of a pressure sensor element 2 as shown by arrows. Those two elements 1 and 2 have the same electric characteristics and the same structure and are fitted in the same direction, the elements 1 and 2 generate opposite-polarity electric signals corresponding to the pressure PA and pressure PB impressed from the intake holes 4 and 6. Therefore, the two opposite- phase electric signals are applied to a differential amplifier, whose output becomes twice as large as the input signal since the input signals are added eventually, thereby obtaining the fine pressure difference between the pressure PA and pressure PB.

Title: Ultrasonic flaw detector
Inventor: UCHIDA HIROSHI
IPC: G01B17/02
Filed: 1978-11-06
Abstract: PURPOSE: To realize the direct reading of the position of the defect and thus to prevent the erroneous measurement by securing the counting and display for the frequency of the variable oscillator via the rise of the transmission pulse.  
     CONSTITUTION: The high frequency pulse of the fixed cycle sent from generator T is applied to the surface of test sample S via ultrasonic probe P and then enters probe P after reflected by the defect or the bottom surface of the sample. These pulses are then detected and amplified A, and the output turns to the vertical axis input of the CRT via compound circuit W. At the same time mono-multi M1 and M2 which are started by the rise of the transmission pulse transmit the rectnagular waves to drive pulse generators H1 and H2. Thus the pulse of generator H3 is applied to the CRT, and at the same time variable frequency oscillator O is started. The output of oscillator O is counted N and then latched L to be displayed D after code conversion K. As a result, the position of the defective pulse can be detected based on the pulse on the CRT and the display of display unit D.
