Filed: 1990-03-29
Abstract: PURPOSE:To obtain a two-dimensional or three-dimensional computer tomographic image by arranging multiple piezoelectric elements radiating ultrasonic waves in the insertion direction on a plane nearly perpendicular to the insertion direction. CONSTITUTION:Eight piezoelectric elements 1 are arranged on a plane nearly perpendicular to the insertion direction 2 of a ultrasonic probe 3, and ultrasonic waves are transmitted and received by individual piezoelectric elements 1. When the probe 3 is inserted into a hollow organ such as a blood vessel and ultrasonic waves are transmitted and received by the piezoelectric elements 1, reflected echoes from a foreign object on the blood vessel well or in the blood vessel on the center axis of the eight piezoelectric elements 1 are captured. When the amplitude of the reflected echoes is converted into intensity, images 4, 41-45 with eight intensity informations for each reception time can be obtained.

IPC: F23N5/24
Filed: 1987-04-02
Abstract: PURPOSE:To accurately operate an earthquake-proof automatic extinguisher with fine responsiveness in oxygen deficient state by a method wherein the displacement force of a deformation element located on or near the side surface of a combustion cylinder at the location ranging from the upper part to the center part of the cylinder is so applied to an interlocking device that the device is disconnected from a mating part. CONSTITUTION:A one-way-opened door installed at the tip of a bimetal 5 touching an interlocking device 8 is freely opened in the displacement direction at the time of temp. rise and inversely closed in a displacement direction at the time of temp. fall. When oxygen deficient state is formed, the temp. near the center part of the side surface of a combustion cylinder 6 falls down. Then, the bimetal 5 installed at the side surface of the cylinder 6 is displaced to rotate the device 8 with an inverse L-shaped tip part in the direction of the arrow. The device 8 is disconnected from a mating part 13 and falls down by the use of a spring 10 force or under its own weight and an earthquake-proof automatic extinguisher 7 is operated through a working frame 9 to carry out extinction. Even if the one-way-opened door 12 placed at the tip of the bimetal 5 touches the device 8 during the time of temp. rise, the door 12 opens and passes over the device 8 easily.

Title: Method and apparatus for surface structure evaluation
Inventor: MIZUKI JUNICHIRO
IPC: H01L21/66
Filed: 1991-04-15
Abstract: PURPOSE:To enable the yield of photoelectrons by diffraction effect by rotating a sample around an axis vertical to the sample surface. CONSTITUTION:An electromagnetic wave emitted from an electron synchrotron accelerator is made monochromatic by a spectroscope 1 and then strikes a single-crystalline sample 4 set on a rotary table 3. Photoelectrons exited by the electromagnetic wave and released out of the sample 4 enter an electron energy spectroscope 5, so that photoelectrons are detected by a detector 6 to output their yield to a recorder 7. At this time, the sample 4 is spinning by the rotary table 3, thereby enabling averaging of the diffraction effect of photoelectrons. Further, the rotary table 3 is mounted on a goniometer 8 that can change the azimuth of a vertical axis on the sample face. Measurement is made by recording values of an electron detector 6 while the energy of an incident electromagnetic wave is varied by the spectroscope 1. This process enables the yield of photoelectrons without being affected by diffraction effect.
