Filed: 1982-09-02
Abstract: PURPOSE:To detect the height of a fluidized bed in reference to a variation in temperature in a direction of gravity at a thermal conducting part by a method wherein the thermal conducting part for conducting the fluidized bed temperature to an outer part is formed along the wall surface of the main body of the fluidized bed. CONSTITUTION:Spacer plates 7 and water pipes 6 are integrally formed to make a membrane structure of entire wall 5. The width of the partial spacer plate of a wall surface is wider than that of the other spacer plate so as to prevent a cooling effect caused by the water pipes at both sides from being applied to the central part of the spacer plate 7a. In the inside of the wall surface contacting with a fluidized bed 1, a refractory material layer 8 is removed along the spacer plate 7a. Thus, fluidized bed medium forming the fluidized bed 1 is directly contacted to the spacer plate 7a at the thermal conducting part 9, and the heat at the fluidized bed 1 is conducted to the outside. A sensing of temperature at the thermal conducting part 9 is performed with a plurality of thermocouples arranged at the thermal conducting part 9 and as shown it may easily be performed with an infrared rays photographing device 11.

Filed: 1987-06-17
Abstract: PURPOSE:To eliminate effect of a noise on a transmission path completely, by judging whether an angle pulse the next to arrive is normal or not in an arrival forecast time zone of an angle pulse and the angle pulse to arrive is abandoned or added alternatively when it is not normal. CONSTITUTION:An angle pulse transmitted from an encoder 10 is supplied to a subsequent pulse time forecasting device 3 through a transmission path 101, an angle pulse detector 1 and a pulse interval measuring device 2. Then, a data pertaining to a forecast time zone forecast with a forecasting device 3 is supplied to an angle pulse decision output device 4. Angle pulses are supplied from the detector 1 to an output gate circuit 41 and a decision circuit 43 in an output device 4. When the subsequent angle pulse supplied from the detector 1 arrives in the forecast time zone, the circuit 43 judges that the incoming angle pulse is normal and outputs the angle pulse through the circuit 41. Here, when the subsequent angle pulse fails to arrive even beyond the forecast time zone, loss thereof is determined to occur owing to noises on the transmission path 101 and an angle pulse is inserted additionally. When any pulse arrives before the forecast time zone, it is judged to be a noise pulse to gate off the circuit 41.
