Title: Load cell
Inventor: HAMA KAZUAKI
IPC: G01G21/23
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To obtain a load cell in which a load in the vertical direction can be transmitted accurately to a strain generating body without increasing the thickness of the load cell itself by surrounding a core part being bonded to a load base with an elastic body and inserting a resilient body holder into a load receiving part body thus constituting the load receiving part. SOLUTION: Load of an object being weighed mounted on a load base acts, as a vertical load, on the load receiving part 2 of a load cell 1 to cause deformation of a strain generating part 3. Stain at the strain generating part 3 is detected by strain gauges 4a, 4b attached to the rear surface at a thin part 3a of the strain generating part 3 in order to measure a load acting on the load cell 1. Since the load receiving part 2 of the load cell 1 comprises a core part 2a being bonded to the load base and an elastic body 2b of urethane rubber, or the like, surrounding the core part 2a, horizontal load or inclination load incident to unloading of the object being weighed or temperature variation is absorbed and relaxed by the elastic body 2b. Since the strain generating part 3 is deformed only with a vertical load, the load can be measured accurately and the load cell 1 can be protected against damage due to horizontal load or inclination load.

Title: Tool gripping device of machine tool
Inventor: KAMEYAMA IKUO
IPC: B25J15/04
Filed: 1995-06-23
Abstract: PURPOSE: To prevent a tool from dropping by applying the force to one arm member of a grip for gripping a tool in the direction of opening, interlocking with the other arm member if the force in the direction of opening is applied only to the other arm member, whereby the repulsion is applied to a compression spring provided for holding a tool to retain the force for gripping the tool. CONSTITUTION: The dead load of a tool holder 5a works only on the lower arm member 14b of a grip so that the lower arm member 14b is about to turn in the direction of opening. The arm members 14a, 14b, however, have gear parts 33, 35 thereof meshed with each other, so that the upper arm member 14a is forcedly caused to open. Accordingly, the repulsion of a compression spring 32 largely acts upon the arm members 14a, 14b not to be opened in a large scale. Thus, the tool holder 5a gripped by the grip 14 can be prevented from dropping.

Title: Evaluation of serum information
Inventor: OKAJI MAKOTO
IPC: G01N33/50
Filed: 1982-09-09
Abstract: PURPOSE:To eliminate erroneous judgement by calculating absorbances of light individually with two different wavelengths in a serum specimen itself to be analyzed employing first and second reagents to determine whether the specimen is normal or abnormal based on the two absorbances. CONSTITUTION:A filter for 340nm is set between a transparent reaction tube and a light source. A first reagent alone is placed into the reaction tube and at the subsequent set time, while a second reagent is placed to detect absorbance A1 after (t)min. Variation amount DELTAA1 in the absorbance for (t)min. is determined and subtracted therefrom and the absorbance Af of the first reagent only is determined. Then, a specimen and the first reagent are placed into the reaction tube, while the second reagent is placed at the subsequent set time to obtain the absorbance and the variation in the absorbance after (t)min. This gives the sum As of the absorbance of the specimen itself and the absorbance of the first reagent. The value Af is subtracted from the absorbance As to determine the absorbance of the speciment itself. Likewise, a filter for 410nm is set to find the absorbance of the same specimen itself. The two kinds of absorbances thus obtained enables discrimination between normal and abnormal natures of the specimen thereby eliminating erroneous judgement.
