20150107203 | MOLD-PREVENTING AIR FILTER FILTRATION MEDIUM AND MOLD-PREVENTING AIR FILTER - A mold-preventing air filter filtration medium loaded with a water-retaining macromolecule polymer, a mold-preventing agent, and a binder resin, is formed by immersing a filter material or a reinforcing nonwoven fabric (a backing material) in a mold-preventing composition in which the water-retaining macromolecule polymer, the mold-preventing agent and the binder resin are dissolved, and drying the filter material or the reinforcing nonwoven fabric. The reinforcing nonwoven fabric (a backing material) may be bonded to a filter material to form a mold-preventing air filter filtration medium. A mold-preventing air filter includes the mold-preventing air filter filtration medium that is pleated and accommodated in a frame. | 04-23-2015 |

20090293295 | AZIMUTH CALCULATION PROGRAM AND ELECTRONIC COMPASS - An azimuth calculation program is a computer-executable program that performs an azimuth calculation using output of a magnetic sensor. The azimuth calculation program includes a first step of generating one triangle in three-dimensional space using three output values of a magnetic sensor unit, a second step of determining a circumcircle of the triangle, and a third step of performing an azimuth calculation using center coordinates of the circumcircle and output values of the magnetic sensor. | 12-03-2009 |
20120078562 | GEOMAGNETIC SENSING DEVICE - A controller includes a calibration unit, an offset error correcting unit, an operation unit, and the like. The calibration unit obtains a reference point of an output of a magnetic sensor, and performs offset correction. The offset error correcting unit is capable of performing operation processing for both the correction of a major offset error and the correction of a minor offset error by using a radius (the magnitude of a geomagnetic vector) of a virtual circle or a virtual sphere, appropriately and easily correcting the offset error with a small amount of operation, and reducing the burden to the controller. | 03-29-2012 |
20120078571 | GEOMAGNETISM SENSING DEVICE - An X-axis sensor, a Y-axis sensor, and a Z-axis sensor that detect a geomagnetic vector are provided, and the direction of the geomagnetic vector is sought on a spherical coordinate from the detection output of each sensor. A reference axis is determined in the spherical coordinate, a hypothetical central point is sought on the reference axis depending on data of two coordinate detection points, a perpendicular line to a plane that includes vectors from the hypothetical central point to the respective data is sought from the cross product of the vectors, an axis that is parallel to the perpendicular line and passes through an origin is set to be a calculated rotational axis, and movement centered around the calculated rotational axis is specified. | 03-29-2012 |
