Title: Ultrasonic probe
Inventor: KAWAN STANT
IPC: A61B8/08
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To efficiently receive a harmonic component generated according to the nonlinear behavior of an ultrasonic contrast medium when an ultrasonic wave is applied to the ultrasonic contrast medium. SOLUTION: A piezoelectric ultrasonic wave vibrator 3 for transmission and a high polymer piezoelectric vibrator 1 for receiving are stored in one case.

Title: Vapor-liquid two phase flow branch pipe
Inventor: MINATO AKIHIKO
IPC: F25B41/00
Filed: 1992-12-07
Abstract: PURPOSE:To inhibit the generation of liquid drops induced by recoil, and what is more, to hold the liquid at a branch section once and then allow the liquid to flow out to a downstream sided pipeline and distribute the percentage of vapor and liquid equally by installing a structural material which obstructs the flow to a pipe wall where two phase stream flowing into a branch line is collided. CONSTITUTION:A structural material, such as meshes are pasted to a pipe wall 2 where flowing-in vapor and liquid two phase flow 1 is collided. Since the inertia of a liquid portion out of the vapor and liquid two phase flow 1 is larger, the stream flows on straight and collides the meshes 6 where the liquid loses its momentum in the direction at the pipe wall so that no liquid may be scattered by the action of recoil. Moreover, if a selected material of the meshes is easily wet to refrigerant, the liquid spreads all over the meshes 6 by the action of surface tension so that the flow-in structure may be lost when the liquid flows in. As a result, if a differential pressure between a branch portion and a downstream-sided pipeline 7 is equal, the flow rate of the liquid of the downstream-sided pipeline 7 of a branch pipe 5 is identical. Since the inertia of the gaseous body is small, the flow is equally distributed virtually according to the pressure difference, thereby equalizing the percentage of the vapor and liquid.
