摘要： PURPOSE:To provide a manufacturing method of a strain gage in which the degree of freedom of a process is high and whose detection accuracy and stability are good. CONSTITUTION:The surface on a part of one face of a first substrate 18 composed of single-crystal silicon of a p-type or an n-type is doped with low- concentration ions, the p-type is inverted into the n-type or the n-type is inverted into the p-type, and a low-concentration doped layer 19 is formed. Then, a second substrate 21 composed of single-crystal silicon of the same material as that of the first substrate 18 is bonded to a face on the side on which the low-concentration doped layer 19 of the first substrate 18 has been formed, an electrochemical etching operation is performed, regions other than the low- concentration doped layer 19 in the first substrate 18 are removed wholly, and the low-concentration doped layer 19 which has been left on the second substrate 21 by removing the first substrate 18 is used as a strain gage 22.

摘要： PURPOSE:To eliminate the action of a force except an interatomic force among atoms and to enhance the accuracy of measurement by attaching an electric detection means to a cantilever or a joist. CONSTITUTION:A cantilever 20 is deformed by an electrostatic force between an electrostatic charge on a surface of a specimen and a probe 21. The deformation quantity is detected by means of a piezo resistance 22 of an electric detection means provided at a foot part A to be taken outside via patterns 23 so that a force applied to the probe 21 is measured. The cantilever 20 is made of an insulator material and the probe 21 and the resister 22 are electrically insulated from each other so that a voltage of the probe 21 is not influenced by the change of a voltage of the resister 22. Therefore, the action of an electrostatic force except a force among atoms is not generated between the surface of the specimen and the probe 21, thereby improving the accuracy of measurement.

摘要： PURPOSE:To provide a driving mechanism suited for miniaturization by obviating the necessity of taking operating fluids in and out from the outside. CONSTITUTION:A thermally expanding member 2 is sealed in an elastic member 1 so formed to freely expand and contract in specified directions, and a heating member 3 is disposed in the thermally expanding member 2. A heat control means is provided which controls driving of the heating member 3 to regulate the temperature of the thermally expanding member 2, thereby causing expansion and contraction of the elastic member 1. The temperature of the thermally expanding member 2 in the elastic member 1 is controlled by the heat control means, so as to enable the expansion, bending and twisting motion of the elastic member 1 without taking fluids in and out from the outside, as in the case of conventional methods. Also, a pump for taking fluids in and out from the outside as in the case of conventional methods is not necessary so that a device can greatly be miniaturized.

摘要： PURPOSE:To adjust a pad pressure to a proper value within a double feed- preventing range by providing a sensor for detecting the pad pressure in the case that a friction pad is brought into contact with the peripheral surface of a friction roller through paper. CONSTITUTION:A detecting sensor 13 of a pad pressure is provided between a friction pad 6 and a manually-operated moving member 8. In the case of wearing the friction pad 6, by a degree of corresponding to this wearing amount, a spring 12 is placed in an extended condition to decrease the pad pressure. On the other hand, since a space between a supporting member 10 and a screw 8 is spread, an indicating value of a tension gage 13 is changed to detect decrease of the pad pressure. In the case of decreasing the pad pressure displaced from a double feed-preventing range, the screw 8 is turned by hand and moved to a side of a friction roller 4, and the pad pressure is returned to a proper value.
