摘要： PROBLEM TO BE SOLVED: To provide a new conductive substance in a gel state, having conductivity which has not been conventionally available. SOLUTION: The conductive gel substance 1 has, as a main component, oil or ionic liquid, or a dispersant 2 constituted of oil or ionic liquid and a conductive particle 3. When a mixture in which the dispersant 2 and the conductive particles 3 are mixed in a certain ratio is put in a container 4 and is kneaded, the conductive particles 3 are dispersed nearly uniformly in the dispersant 2. However, since the conductive particles 3 have low compatibility with the dispersant 2, in certain time after kneading has been stopped, the conductive particles 3 coagulate partially in the dispersant 2 and a chain structure, to become a conductive path is formed. Thus, the chain structures spread out uniformly in the conductive gel substance 1, a stable gel state can be obtained, and furthermore, resistance value can be made low. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an electronic component employing conductive gelatinous substance especially and excellent in linearity characteristics with simple structure while having long life and capable of being used by DC. SOLUTION: The conductive gelatinous substance 1 is employed as a resistance body for a variable resistor whereby the variable resistor excellent in linearity characteristics can be formed by a simple structure. Further, the conductive gelatinous substance 1 can maintain stabilized gelatinous state at the wide range of temperatures whereby long life can be realized and, further, using by DC is possible. On the other hand, a seesaw type variable resistor can be formed of a simple structure by using the conductive gelatinous substance 1. Furthermore, the variable resistor having feeling different from the feeling of a button formed of plastic, elastic body or the like and which has not been experienced before, can be realized by employing the conductive gelatinous substance 1.

摘要： PROBLEM TO BE SOLVED: To provide a load sensor capable of preventing loosening with the passage of time, reliably mounting a straining body to a spindle, and obtaining high reliability without variations in the characteristics of distortion elements product by product. SOLUTION: After a nut 8 is spirally engaged with a bolt 3, the bolt 3 is sequentially inserted in a washer 6 and a tube spacer 10. Then the spacer 10 is inserted in the shaft hole 2a of the straining body 2. The bolt 3 is inserted in a washer 5, a nut 7 is fastened, and a bobbin-shaped unit body comprised of the washers 5 and 6 and the tube spacer 10 is sandwiched and pressed along the axial direction of the bolt 3 by the pair of nuts 7 and 8. The straining body 2 of which the plate thickness is smaller than the height size H of a straining body holding pace 11 is arranged with a gap in the holding space 11 between both washers 5 and 6. Therefore, even when the washers 5 and 6 are fixed to the bolt 3 with a strong pressing force, it is possible to prevent the pressing force from dirtily acting on the straining body 2.

摘要： PROBLEM TO BE SOLVED: To extend the detection range of a strain sensor, and to make its detection precision higher by widening the range of strain in the elastic region of the metallic base material of the strain sensor, and reducing residual strain. SOLUTION: As a metallic base material 2 for the strain sensor 1, two-phase system stainless steel comprising Mo is used. When an insulating layer 3 and electrodes 4 and a resistor 5 are formed on the base material 2 by burning, the alpha phase of the stainless steel is transferred to the sigma phase by heat treatment of the burning, and strain applicable within the range of the elastic region spreads and residual strain decreases also. Consequently, a strain sensor having a wide detection range, and excellent in returnability to an origin, can be obtained.
