Abstract: The invention makes it possible to measure a lateral displacement amount of a vehicle accurately in a short time on a bench testing machine without damaging a vehicle body and tires. Respective rollers 1F, 1R on which respective wheels WF, WR of the vehicle A are placed respectively are made movable in a lateral direction. In a state in which the respective wheels WF, WR are rotating at a predetermined speed, lateral forces (cornering forces) acting on the respective rollers 1F, 1R are detected by respective detectors 3. Then, a yaw angle speed when the vehicle A is brought into a state of steady circular turning is calculated based on the lateral forces acting on the respective rollers 1F, 1R and the lateral displacement amount is calculated from the yaw angle speed.

Abstract: When a plurality of toner containers mounted on a developing rotary unit are simultaneously determined as toner-absent toner containers, toner container replacement may not be efficient because toner containers are replaced at a replacement position. Therefore, when the toner containers mounted on the developing rotary unit are simultaneously determined as toner-absent toner containers, a toner container to be preferentially replaced is selected so as to be able to be placed at a replacement position by considering the usability of the toner containers.

Abstract: A device used to facilitate the accurate shooting of an archery bow. The device includes horizontally and vertically adjustable support structure for attaching the device to a bow. Moreover, the device includes a base, a guard and sight pins. The base includes arcuate channels sized for receipt of sight pins and arched to ensure that the sight pins are aimed at the archer's eye regardless of vertical spacing. The sight pins include an offset-Y-shaped fiber support and a light-gathering fiber. The light-gathering fiber comprises a length of fiber optic material with a sighting point on each distal end thereof. The offset-Y-shaped fiber support is an offset-Y-shaped member whose offset allows for placement in either of two spaced arcuate channels while maintaining the targeting axis position of the sighting points. The guard, which encircles the sight pins, includes three fiber optic fibers spaced about its diameter to allow for low-light alignment.

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.
