Abstract: A method for measuring a directional of a body in a three-dimensional space defined by an X-axis (magnetic north), a Y-axis, and a Z-axis is proposed. A geomagnetic force along an x-axis, which is the direction towards which the body points and an x-axis tilt angle, which is an angle between the horizontal plane and the x-axis, are detected. The x-axis tilt angle is determined as a rotation angle, which an angle by which the x-axis needs to be rotated around the Y-axis so as to be in the XY-plane. An azimuth of the body is calculated from the geomagnetic force and the rotation angle.

Abstract: A washing machine has a partial washing apparatus fitted on an outer surface of a main unit having a washing tub housed therein. The partial washing apparatus is movable between an use position and a non-use position. When the partial washing apparatus is in the use position, its washing portion faces a laundry entrance from outside the main unit; when the partial washing apparatus is in the non-use position, its washing portion is retracted from the position in which it faces the laundry entrance. The washing portion achieves washing by using supersonic waves generated by a supersonic vibration device. The laundry entrance is covered with a lid composed of a front lid and a rear lid coupled together so as to be foldable in two. The rear lid has a gate opening formed therein to let the partial washing apparatus pass through. The gate opening is partially or completely closed by a tray for sustaining a piece of laundry.

Abstract: A method for measuring a directional of a body in a three-dimensional space defined by an X-axis (magnetic north), a Y-axis, and a Z-axis is proposed. An x-axis tilt angle, which is an angle between a horizontal plane and an x-axis, which is the direction towards which the body points, and a y-axis tilt angle, which is an angle between a y-axis orthogonal to the x-axis and the horizontal plane, are detected. The x-axis and the y-axis are converted so as to be in the horizontal plane using the x-axis tilt angle and the y-axis tilt angle. A primary azimuth between the X-axis and the x-axis converted is calculated. An azimuth error angle included in the primary azimuth is extracted based on the x-axis tilt angle, the y-axis tilt angle, and the primary azimuth.

Abstract: A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage branched from an exhaust pipe of the engine, which is opened by a switch-over valve at starting of the engine to introduce the exhaust gas such that the adsorbent adsorbs unburned HC in exhaust gas generated by the engine and is closed such that the adsorbent desorbs the adsorbed HC and the desorbed HC is thereafter recirculated at a position upstream of a catalyst. Based on the fact, due to the adsorption effect, the HC concentration at a downstream point is lower than that at an upstream point, in the system, the concentration of the HC introduced in the bypass exhaust gas passage in the adsorption mode is detected and compared with a threshold value and the degradation of the adsorbent is discriminated, thereby enabling to improve the discrimination accurately.

Based on the fact that the HC concentration rising time interval becomes short as the adsorbent degrades and adsorption capacity decrease, the time lapse since engine starting until the detected HC concentration exceeds a predetermined level is measured and is compared with a threshold value such that the adsorbent is discriminated to be degraded if the measured time lapse is less than the threshold value, thereby enabling to improve the discrimination accurately.

Abstract: A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage branched from an exhaust pipe of the engine, which is opened by a switch-over valve at starting of the engine to introduce the exhaust gas such that the adsorbent adsorbs unburned HC in exhaust gas generated by the engine and is closed such that the adsorbent desorbs the adsorbed HC and the desorbed HC is thereafter recirculated at a position upstream of a catalyst. In the system, an inflow amount and outflow amount of HC flowing in and out of the adsorbent are determined based at least on the engine operating conditions and the detected concentration of HC. Then, the ratio therebetween is calculated and compared with a threshold value and if the ratio is less than the threshold value, the adsorbent is discriminated to be degraded, thereby enabling to improve the discrimination accurately.
