Title: Temperature measuring method using reference electrode internal solution
Inventor: IWAMOTO YOSHIKAZU
IPC: G01N27/416
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To precisely measure the temperature of a solution to be measured with good responsiveness by dipping a temperature measuring electrode in an internal solution having the same component as the internal solution of a reference electrode but differed in concentration, and converting the temperature from the Nernst's equatior on the basis of the potential difference between both the electrodes. SOLUTION: In a pH meter, a temperature electrode 1 is made of the same material of a reference electrode 5, and the internal solution 2 of the temperature electrode 1 has the same component but is differed in concentration from the internal solution 6 of the reference electrode 5. Since it is the prerequisite that the concentrations of both the internal solution 2, 6 are never changed in the use of the Nernst's equation, the internal solution 6 of the reference electrode 5 is gelled, thereby, the change of its concentration is suppressed, and a high measuring precision can be stably kept.  In the Nernst's equation: ΔE=(RT/nF)×ln(C/Co), C represents the concentration of the temperature electrode internal solution, Co represents the concentration of the reference electrode internal solution, R represents a gas constant, F represents a Faraday constant, (n) represents a valency, and In represents a natural logarithm, and the potential difference ΔE is proportional to absolute temperature T.

Title: Pressure limiting valve
Inventor: ERUNSUTOODEIITAA SHIEEFUAA
IPC: B60T8/34
Filed: 1991-09-18
Abstract: PURPOSE: To remove the hysteresis having a bad effect on the closing characteristic of a pressure limiting valve. CONSTITUTION: A pressure limiting valve 21 has a valve closing body (ball 52), and the valve closing body is subjected to a hydraulic opening force and also to a closing force generated by a compression spring 49. Further, a tapped 55, which passes through a sealing ring 51 and is exposed to a control pressure, is also capable of acting in a closing manner upon the pressure limiting valve 27. When there is no operative control pressure, the tappet 5 is pushed back by the opening of the limiting valve 27 and retained in this position by frictional forces brought about by the sealing ring 57. The opening and closing cycle of the pressure limiting valve 27 is free of frictional forces. The pressure limiting valve 21 is suitable for use in a hydraulic motor vehicle brake system.

Title: Inspection method for quality of surface
Inventor: YAMAMOTO KAZUO
IPC: B21C51/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide an inspection method in which the number of components such as imaging elements or the like can be reduced by a method wherein a rectangular image having a large aspect ratio on a material to be inspected is formed on a two-dimensional imaging element which is a sqaure shape of a rectangular shape having a small aspect ratio. SOLUTION: The surface of a slab as a material to be inspected is irradiated with slit light from a light source 01, and its reflected light is condensed by a lens 03. After it has been condensed, it is condensed on a two-dimensional imaging element 05 at an imaging means via an image compression means 04 using a convex mirror. At this time, an image which is radiated on the output side of the means 04 becomes an image in which the image of the slab has been compressed in the width direction so as to be a distorted shape, and the image is formed on the element 05. Consequently, the image which is transversely long in the width direction of the slab can be formed on the element 05 which is a square shape of a rectangular shape having a small aspect ratio.  An image 06, for measurement of a slab surface shape, which has been obtained is analyzed by an image processor 07, and the shape on the surface of the material to be inspected is measured. Thereby, the number of imaging elements can be reduced, the maintainability of an apparatus is enhanced, and the inspection time of an inspection method can be shortened.
