The phototriodes are arranged on the phototriode base at certain inward angles; the filter plate is arranged on the phototriode base; and the difference of luminous fluxes of illuminated faces of two phototriodes reflects the angle relationship between the sensor probe and incident rays; and electric signals are changed into servo signals through further processing of the sensor circuit to drive a servo mechanism. If and only if the luminous fluxes of the illuminated faces of the two phototriodes arranged at the certain inward angles are the same, the current capable of passing the two phototriodes is equal, and the sensor is aligned to a light ...

Geomagnetic survey square ring sample perforating apparatus

The present invention relates to a magnetic survey square cycle sample perforating device. The present invention comprises a frame (1), a platform (2) used for fixing the magnetic survey square cycle (5), two plugging sheet mechanisms (3) and an unloading sheet mechanism (4) used for unloading the sample on the plugging sheet mechanism in the magnetic survey square cycle. The two plugging sheet mechanisms (3) are respectively arranged on the side of the magnetic survey square cycle (5). The plugging sheet directions of the two plugging sheet mechanisms (3) are vertical to each other. The platform (2), the plugging sheet mechanism (3) and the unloading sheet mechanism (4) are all arranged on the frame (1). The magnetic survey square cycle sample perforating device of the present invention changes the traditional manual sample perforating method and realizes the mechanization of the magnetic survey square cycle sample perforating. So the speed of the sample perforating is high. The production ...
