Title: Utm coordinate converter
Inventor: HAYASHI TOMIHIKO
IPC: G01S7/295
Filed: 1984-01-30
Abstract: PURPOSE:To enable the calculation of relative positions at two points in two adjacent UTM coordinate systems by converting UTM coordinates. CONSTITUTION:Two UTM coordinate systems are established as L(XL-YL) and M(XM-YM) coordinate systems and A and B as points in the L and M coordinate systems respectively. The L and M coordinate systems are separately move parallel to make the coordinate systems with the points A and B as origin respectively, as XA-YA and XB-YB and then, done so again to make the coordinate systems with a desired point C as origin on the boundary as X'A-Y'A and X'B-Y'B separately so that the coordinates (x0, y0) will be determined for the point C on XA-YA and those (x1, y1) for the point B on X'B-Y'B. The angle between the boundary and Y'B axis at the point C is set at beta. Since the L and M coordinate systems are linearly symmetrical with respect to the boundary, beta is given to the angle between the boundary and the Y'A axis. Therefore, the angle alpha between X'A-Y'A and X'B-Y'B equals 2beta to enable the point B to be translated to the coordinates (x2, y1) of X'A-Y'A. Thus, by the addition of the coordinates (x0, y0) at the point C on XA-YA thereto, the coordinates of the point B expressed by the M coordinate system is translated to the coordinates (x, y) in the L coordinate system.

Title: Photoelectric rotary encoder
Inventor: WADA TATSURO
IPC: G01D5/36
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To constitute a light receiving element so as not to receive influence of an oblique light with a small size by forming shapes of photosensors of the element in a T-shape with the relationship between an erected image and an inverted image of adjacent photosensors. SOLUTION: A light receiving element 7 of the photoelectric rotary encoder has, for example, three photosensors 7a on its surface. The photosensors 7a are formed in a T shape, and the adjacent photosensors 7a have the relationship between an erected image and an inverted image. A standing bar of T shape of the photosensor 7a is adjacent to that of the adjacent photosensor 7a. Accordingly, a gap between the photosensors 7a is larger than the interval of the photosensors 7a. Even if the photosensors 7a are disposed densely, the gap therebetween can be ensured for the degree of no fear of electric interference, and hence it is not necessary to enlarge the element 7.  If an oblique light is received or light is not emitted to right side of the lateral bar of the T shape of the photosensor 7a, an area emitted with the light is increased at a left side, and hence its effective photosensing area is not altered from the case of a perpendicular light.

Abstract: PURPOSE:To attain the sure running of an unmanned carrier by detecting a magnetic field generated by a starting induction line used for transmission of the necessary information and controlling the unmanned carrier based on the information obtained by combining the frequencies of the starting induction line. CONSTITUTION:When an unmanned carrier D is guided via an electromagnetic induction line, a starting induction line 1 is detected (ON) at a position (a) together with the induction lines F2-F4 detected (ON) at a position (b), and the induction lines F2 and F4 detected (ON) at a position (c) respectively. Thus the detected frequency data (starting line) is obtained. The carrier D contains the data stored in a memory and judges its present position when the coincidence is obtained between the data and the contents (F2, or F2+F3+F4 or F2+F4) of the detected frequency data. As a result, the sure running of the carrier D is attained.
