Title: Self-check type flame sensor
Inventor: HIRATA SUSUMU
IPC: F23N5/08
Filed: 1984-11-20
Abstract: PURPOSE:To detect whether there is flame or not and whether a flame sensor is faulty or not by arranging a liquid crystal cell which is driven to enter a transparent and an opaque mode alternately and repeatedly at a specific period on the front surface of a photodetecting element, and detecting a signal obtained at the photodetecting element by a detecting circuit with a fail-safe function. CONSTITUTION:The liquid-crystal cell 3 arranged between flame 1 and the photodetector 4 is driven with output voltage pulses of a driving voltage source 5 to enter the transparent mode and opaque mode alternately at a specific frequency. When the liquid-crystal cell 3 is transparent, light from the flame 1 which is converged by a lens 2 is incident on the photodetector 4 through the liquid-crystal cell 3 and converted into an electric signal, which is detected as a pulse output of the specific frequency by a pulse detecting circuit 7 having the fail-safe function through an amplifier 6. Thus, whether there is the flame 1 or not and whether the flame sensor is fault or not are detected.

Filed: 1986-10-14
Abstract: PURPOSE:To unattendedly drive a lobby or the like with any guide line by providing a short distance measuring instrument and a gyro to both sides of a treveling track and applying steering based distance information and gyro output information. CONSTITUTION:A narrow range finding sensor is provided at both sides of a traveling track main body 4 and a relative angle from a wall is computed by a computer 25 from range finding information. Moreover, the computer discriminates the range of relative angle to correct the drift of gyro output to adds the relative angle and the gyro output. Access information of an obstacle on a path is obtained from the range finding sensor and when a prescribed distance is reached, the track is run in parallel with a wall of the obstacle and then reversed by the generation of a control output to drive steering means 20-32. Moreover, the enabled/disabled range finding is discriminated by the computer 25 and if the measurement is disabled, the track is run straight by a gyro output, and if measurement is enabled, the track is subjected to steering by a sum output between the relative angle with the wall and the gyro attitude angle information. Through the constitution above, the automatically guided vehicle traveling device is obtained, which is run uniformly in a lobby without guide lines.
