Title: Examination apparatus using nuclear magnetic resonance
Inventor: YABUSAKI YUKIO
IPC: A61B5/055
Filed: 1988-06-08
Abstract: PURPOSE:To equally press the abdomen and to perform oppression improved in operability, by providing a freely extensible packing material inside a signal detection coil. CONSTITUTION:A hollow packing material 30 made of freely extensible material quality (e.g., rubber) is provided inside a coil 8. In a state before a fluid such as air is sent in the packing material 30 (that is, a valve 31 is closed), the inner diameter of the coil 18 does not almost become small, because the hollow packing material 30 is made of the freely extensible material quality. The inner diameter of the coil 8 is only reduced by the dimension corresponding to the thickness of the packing material 30, for example, several mm and, therefore, a human body 20 can be easily inserted. When a fluid such as air is injected in the packing material 31, the human body 20 is equally pressed from the periphery by the pressure of the fluid such as air injected in the packing material 30. By adjusting this pressure from the outside, the degree of oppression can be adjusted and body motion can be suppressed.

Filed: 1983-07-29
Abstract: PURPOSE:To decrease the production of nitrogen oxide, and elongate the life of oxidization catalyst, by lowering the temperature of roasting exhaust gas below that of the cooled exhaust or fresh air before passing through the catalyst. CONSTITUTION:The exhaust gas from the roast chamber 1 is deodorized with the oxidization catalyst 17, and the cooled exhaust from the cooling chamber 4 is deodorized with the oxidization catalyst 17. In the above roasting apparatus, the roasting exhaust gas before passing through the oxidization catalyst 17 is combined with the cooled exhaust gas before passing through the oxidization catalyst 17, or if there is no cooled exhaust, combined with fresh air to decrease the temperature of the roasting exhaust gas. By this process, the temperature of the combined exhaust gas passing through the oxidization catalyst 17 is adjusted to the temperature effective to decrease the production of nitrogen oxide and exhibit the deodorization effect (e.g. about 300 deg.C). Consequently, the production of nitrogen oxide can be decreased and the life of the oxidization catalyst can be extended.

IPC: G01N9/24
Filed: 1990-05-31
Abstract: PURPOSE: To develop an on-line measuring apparatus without needing contact with a web material by utilizing two separated laser sources having beams for catching the web material. CONSTITUTION: A measuring apparatus is provided with a first laser source 10 directed towards a web material 12, a second laser source 14 and a light sensor 16. A distance between incident points of beams from the laser sources 10, 14 on the web 12 is known. The laser source 10 generates local spot heating for generating thermal expansion on the web 12. This thermal expansion generates ultrasonic wave propagated through the web 12. The supersonic waves allow the beam from the laser source 14 to be reflected by the web 12 and the reflected beam is caught by the light sensor 16. A passage time between the transmission of the first beam to the web 12 and the reception of the second beam by the light sensor 16 is measured so that the speed of the ultrasonic wave in a material can be determined.  The speed of the supersonic wave is combined with the measured value of the material density to determine the strength of the material.

Abstract: PROBLEM TO BE SOLVED: To control the strip shape of its tip part before obtaining the output of a shape meter. SOLUTION: Just after the tip part of a material 1 to be rolled has passed a rolling mill 2, the strip shape can not be measured by a shape meter 4. Therefore, at this time, according to a calculated set value PCAL from a setup computer 5 and an actual rolling load PFB from a load cell 6, the coefficient αof load fluctuation is obtained by a computing element 7 for the coefficient of load fluctuation. From this α and a set roll bending pressure FCAL from the computer 5 and a control gain (g), a bending pressure correction quantity ΔF is obtained by a bending pressure correction quantity computing element 8. The ΔF is added to a set roll bending pressure FCAL via a hold memory 9, and is inputted to a bending pressure controller 10. According to this value, the roll bending pressure of the rolling mill 2 is controlled by the roll bending pressure controller 10.
