摘要： PURPOSE:To realize a thermometer for cryogenic temp. which has a large change characteristic of resistance/temp. and decreases resistance change by a magnetic field by utilizing the resistance characteristic of an amorphous silicon film. CONSTITUTION:The amorphous silicon film 2 is formed on an insulating substrate. An electrode 3 having a comb tooth-shaped part 3b and an electrode 4 having a comb tooth-shaped part 4b existing in the position where said part is relatively fitted into the comb tooth-shaped part 3b are formed. The thermometer 200 for cryogenic temp. formed in such a manner decreases the resistance change with the magnetic field and has the large resistance/temp. change characteristic and therefore, said thermometer is suitable for temp. detection in a super conductive electromagnet, MHD generator, etc.

摘要： PROBLEM TO BE SOLVED: To provide a strain gage capable of measuring the self-contracting behavior of concrete just after the cement material is placed and useful for making clear the mechanism of a cracking phenomenon of the concrete caused by the self-contraction, for controlling cracking, and for performing design. SOLUTION: This strain gage 4 is formed as a thin-walled oblong parallelepiped molding 3 by air-tightly coating the whole of a strain gage element 1 and the proximity of a connection part between the gage element 1 and lead wires 2 with a low-elasticity silicone resin. The gage 4 is embedded in just-mixed concrete to be measured and the lead wires 2 are connected to a strain measuring instrument. The gage element 1 in the molding 3 embedded in the concrete varies in resistance value due to its self-contracting behavior while the just- placed concrete in a flowable state becomes hard. The resistance value is measured by the measuring instrument and converted into displacement.

摘要： PURPOSE:To hold high damp proof and electric insulation over a long period of time by surely isolating the whole surface of a strain gage affixed to a strain-caused part and an object to be measured and the surface of the affixed part of the strain-caused part, on which the strain gage is affixed, from the outside air. CONSTITUTION:A strain gage 1 on which a laminate layer 10 is made on a surface and a relay terminal 6 are affixed on the predetermined part of a strain- caused part 5 and a coating layer 9 composed of organic material is formed on the surface of each member including the strain gage 1, gage leads 7, the relay terminal 6 and the ends of lead wires 8. Thereafter, conditioning treatment of electroless plating is conducted on the whole surface of the coating layer 9 and the surface of the affixed part of the strain-caused part, after a washing process, activating treatment is performed, for instance, Ni contained in activating treatment liquid is deposited on the coating layer and the whole surface of the affixed part and a metal plating layer is formed. Thereby damp proof of the strain gage 1 is remarkably improved and the detection performance of the strain gage 1 is highly precisely maintained over a long period of time.

摘要： PURPOSE:To make it possible to attach readily and positively a strain gage to a body to be measured having no flatness, by using a flexible foil shaped strain gage element whose electric resistance is changed by receiving the physical quantity acting on an object to be measured. CONSTITUTION:A high temperature strain gage 10 is composed of a strain gage element 3, a supporting layer 6 and a gate lead 8. When a body to be measured 1 comprises a nonconductive material, a bonding agent 21 is applied on the body to be measured 1. A surface to be attached 5 of the strain gage element 3 is made to face the side of the body to be measured 1, and the strain gate 10 is bonded. When the body to be measured 1 comprises a conductive material, the strain gage 10 is bonded with the bonding agent 21, in which glass beads 22 are mixed. The quasi-attached structure formed in this way is exposed to high temperature, and the supporting layer 6 is burned out. Then the attached structure is completed. Therefore, the very minute strain gage element 3 can be manufactured. Since the gage element 3 is supported with the supporting layer 6, handling is easy.

摘要： PURPOSE:To improve water proofness and moisture proofness so as to keep the electrical insulation between a resistance element and an object to be measured for a long period. CONSTITUTION:The strain gauge is provided with a resistance element 5 that is bonded on the upper surface of a gauge base 3 by an adhesives 4 and a water-barrier metallic foil 8 consisting of an aluminum or stainless steel thin film that is bonded on the lower surface thereof by an adhesives 9. A gauge tab of the element 5 is connected with a gauge lead 6 by soldering. The surface of the element 5 and gauge base 3 is covered with a laminate 7. A water-proof resin 13 covers the surface of the strain gauge by means of the laminate 7 and it is bonded or melt-bonded to the peripheral part of the base 3. The foil 8 is stuck on an object 1 to be measured by an adhesives 2. In the strain gauge having such a construction, the foil 8 prevents water content from entering the back side of the base 3 and at the same time the laminate 7 and resin 13 also prevent it from entering the surface side thereof, so the electrical insulation can be kept for a long period.

摘要： PURPOSE:To obtain a small-sized, high-output device which has a high gauge rate and a small creep by forming an amorphous semiconductor of a tetrahedral alloy on the surface of a strain inducer, and using it as a strain receiving element. CONSTITUTION:Insulating SiO2 films 7b and 7c are formed on both surfaces of the strain inducer 7 made of a stainless steel plate 7a which has one end put in motion together with an object of measurement (not shown in figure) in one body and also has a weight (not shown in figure) fixed at the other end. The amorphous semiconductor film 7d formed of the tetrahedral alloy (Si:H, SiC, etc.) containing fine crystal and an Al electrode film 7e are formed on the film 7c. The films 7e and 7d are etched to form connection conductor patterns 12-16 and strain receiving element patterns 8-11, and the Al electrode film 7e on the strain receiving element patterns 8-11 is removed. This strain sensing member uses the tetrahedral alloy amorphous semiconductor, so high specific resistance is formed, the high gauge rate and high output are obtained, the size is reduced greatly. Pattern formation is performed directly on the strain inducer 7, so the linearity of the output is good and the creep is small.
