A transparent conductor includes a film-shaped or plate-shaped support and a transparent conductive layer that is disposed on the support and has a surface formed as a rough surface. The surface of the transparent conductive layer is formed so that a maximum peak height that shows a surface roughness of the surface is in a range of 0.35 &#x3bc;m to 0.43 &#x3bc;m, inclusive.

The present invention relates to an acceleration measuring device capable of acquiring the offset for correcting the output of a triaxial acceleration sensor. The invention is provided with an acceleration sensor for detecting the acceleration in a triaxial direction, a data acquisition portion for acquiring the triaxial output data, a data selecting portion for judging whether repeatedly acquired triaxial output data are appropriate to make a selection, a data accumulating portion for accumulating the thus selected triaxial output data, a reference point estimating portion estimating coordinate values of the reference point determined in the three-dimensional cartesian space by referring to the distribution of a predetermined number of accumulated triaxial output data in a three-dimensional cartesian space when each axial component is given as a coordinate value, and an offset correction/calculation portion for correcting the offset of the triaxial output data of the acceleration sensor.

An azimuth measuring device is provided that can obtain offset information when the direction of the azimuth measuring device is arbitrarily changed. The offset information is calculated based on coordinates of a reference point obtained by a reference point estimating system. The azimuth measuring device can obtain the offset information without obtaining erroneous offset information when changing direction.

Azimuth measuring device

An azimuth measuring device capable of calibrating a magnetic sensor without putting load on a user is provided. When a point having amplified output values Sx, Sy, Sz after a sensitivity correction as x, y, z components is arranged on an xyz coordinate system, an offset information calculation section 8 calculates the center coordinates of such a sphere whose surface is located in the vicinity of each point and calculates an x component of the center coordinates of this sphere as a current offset Cx of an x-axis Hall element HEx, a y component of the center coordinates of this sphere as a current offset Cy of a y-axis Hall element HEy and a z component of the center coordinates of this sphere as a current offset Cz of a z-axis Hall element HEz. It is thereby possible to calibrate the magnetic sensor without putting load on the user.
