Filed: 1984-03-09
Abstract: PURPOSE:To reduce the load of a CPU which controls an unmanned carrier by using the photoelectric switches set at the entrance and the exit of a common line and a photoelectric switch set on the unmanned carrier to control the drive of the carrier. CONSTITUTION:When an unmanned carrier 1A gets close to the entrance of a common line 21, a photodetecting part 5 receives the light sent from a projecting part 23A. Thus the carrier 1A is stopped temporarily. Then a projecting part 6 irradiates light to a photodetecting part 24A. In this case, a control part 25 stops the light irradiation of the part 23A and starts the carrier 1A as long as another unmanned carrier 1B is not traveling on the line 21. At the same time, the light projection is not discontinued through projecting parts 23C and 23D even though photodetecting parts 24C and 24D set along drive paths 20C and 20D detect an unmanned carrier. Then the discontinuation of light projection is released for parts 23C and 23D after the carrier 1A travels the line 21 and enters the path 20B and then a photodetecting part 24B is actuated.

Title: Distance measuring instrument
Inventor: NOMURA HIROO
IPC: G01C3/06
Filed: 1992-03-02
Abstract: PURPOSE:To measure the distance to a reflecting object ahead without relying on the sense of sight by measuring the direction angles of reflected light from the object to two light receiving elements and calculating the distance to the object from the two direction angles and reference distance between the light receiving elements. CONSTITUTION:Light emitted from a light emitting element 1 irradiates the front after the irradiating extent of the light is widened through a projection lens 2. Reflected light rays from an object 3 to be irradiated respectively form images on light receiving elements 6 and 7 after passing through image forming lens systems 4 and 5. When the angles of the reflected light rays are measured, L=b.costheta2+c.costheta1 is obtained, where angle B=theta1, angle C=theta2, side BC=L, side AC=b, and side AB=c. In case L is 10cm and the (b) and (c) are several meters, the (b) and (c) become nearly equal to each other and can be regarded as the distance R to the object, since b>>L and c>>L. Therefore, the distance R can be calculated from R=L/(costheta1+costheta2).

Abstract: PURPOSE:To improve a discriminating performance by determining an inspection reference value from a data base wherein the inspection reference value is accumulated for each luminance value at the position of inspection of a building material and from a measured value of luminance and by comparing the data with detected data. CONSTITUTION:A data base wherein a detection reference value is accumulated for each luminance value at a position of inspection is prepared in an image processing device 3. In this state, an object M is set on a conveyor belt 12 and conveyed in one direction at a prescribed speed. When it reaches a prescribed position, an image of the main surface side of the object M is picked up by a CCD camera 1, while a stroboscope emits light synchronously with this image pickup operation and the light becomes a surface emission from the upper side of a stroboscope holding box 13 and irradiates the object M from the rear side thereof. At this time, a luminance meter 15 measures the luminance of the periphery, inclusive of an external light. Since each measured value is inputted to the device 3, the device 3 determines an average value at this time, decides on an inspection reference value corresponding to it and compares data on a detected pixel of the object M with data on the inspection reference value.
