IPC: G01N29/06
Filed: 1985-07-26
Abstract: PURPOSE:To obtain a tomographic image having no distortion even if a probe does not contact a body to be inspected by correcting the display position of a reflected signal in consideration of the refraction of an ultrasonic wave on the surface of the object body. CONSTITUTION:When a control circuit 31 scans the object body 1 with an ultrasonic wave prior to video formation, a position detection circuit 5 outputs such a direction that the delay time t0 from transmission to the reception of the 1st echo is minimum and the distance l1 between the object body 1 and probe 2 in the direction. An arithmetic circuit performs arithmetic on the basis of the distance l1 and the angle theta1 of deflection of the probe to generate a conversion table. When a video is formed, an azimuth angle and an echo position which are obtained by scanning the object body 1 by the control circuit 31 are inputted to the conversion table to obtain coordinates on a screen. Thus, the position relation between the probe and object body is detected automatically through initial operation and used as correction data, so an accurate tomographic image is obtained.

Abstract: PURPOSE:To produce an aromatic crosslinked polymer substituted with iodine which has an excellent X-ray contrast effect and has a high degree of crosslinking by copolymerizing an aromatic vinyl monomer with a difunctional or higher functional aromatic vinyl monomer, and iodinating the resulting polymer. CONSTITUTION:An aromatic vinyl monomer (e.g. styrene) is copolymerized with a difunctional of higher functional aromatic vinyl monomer (e.g. divinylbenzene or trivinylbenzene), and the resulting aromatic polymer having a high degree of crosslinking is iodinated, thereby substituting iodine thereinto to produce an iodine-substituted aromatic polymer having a high degree of crosslinking. The polymer has an excellent X-ray contrast effect. Also, because of the high degree of crosslinking, the polymer has a tough three-dimensional structure. Due to the structure, it exhibits unique insoluble and infusible properties and therefore is high in safety even when the polymer is used as an X-ray contrast medium. Also, it is useful as a reactive intermediate which is used for producing an aromatic crosslinked polymer having a high degree of crosslinking wherein various functional groups are introduced as flame-retardant for plastics.

IPC: G01G13/29
Filed: 1982-09-24
Abstract: PURPOSE:To correct a fall correction value automatically and to improve weighing precision by calculating a current fall correction value on the basis of the last weighing error and fall correction value. CONSTITUTION:An operation part 11 is operated to input a weighing set value, the initial value of fall correction, and a constant to a CPU12.
