摘要： PROBLEM TO BE SOLVED: To provide a transducer capable of monitoring an input circuit with high accuracy. SOLUTION: In the transducer with a CPU clock 10 having the input circuit 2 using an A/D converter 5 for converting an analog signal of a preset frequency into a digital signal, a test signal generation part 11 generates a digital test signal of a test frequency different from the preset frequency by dividing the frequency of a signal from the CPU clock 10, a waveform trimming circuit 12 converts it into an analog test signal and a superimposing part 3 superimposes it on an analog input signal. A generation part 13 generates a sampling signal for the A/D converter 5, of a frequency twice or more of the test frequency, by dividing the frequency of the signal from the CPU clock 10. An effective value for the test signal in the superimposed signal (the digital superimposed signal) after converted in the input circuit 2 is found by a first effective value computation part 14 and an effective value for the analog test signal after converted by the A/D converter 5 is found by a second effective value computation part 17, and the abnormality of the input circuit 2 is determined through the comparison of the outputs of both computation parts 14, 17 with each other by a determination part 18.

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber thermometer enhanced in the intensity of fluorescence. SOLUTION: One end of an optical fiber 2 is connected to the incoming and outgoing window 11 of an emitter 1 having an integrating spherical shape with the incoming and outgoing window 11 and emitting light in a characteristic according to temperature in the incoming and outgoing of an exciting light. A light source 5 and an optical detector 6 are connected to the other end of the optical fiber 2 through a two-branched optical fiber. The exciting light of the light source 5 entering through the incoming and outgoing window 11 is enhanced by the integrating sphere internal repeated reflection, and applied to the emitter 1. The fluorescence from the excited emitter 1 is increased in intensity without being leaked to the outside by the integrating sphere internal repeated reflection and outputted to the optical detector 6 via the optical fiber 2. The measurement accuracy of the optical fiber thermometer is improved by enhancing the intensity of the exciting light and the intensity of the fluorescence. The material of the emitter 1 preferably consists of monocrystal of ruby (Al2 O3 with Cr added thereto), monocrystal of spinel (MgAl2 O4 with Cr added thereto), or quartz with rare earth element such as Er (erbium), Nd (neodymium), Tm (thulium) or the like added thereto.

摘要： PURPOSE:To provide the internal temperature controller for the diffusion furnace which is fast in response speed and converged in a short time. CONSTITUTION:A master controller 10 generates a master controller output PN1 on the basis of the difference between a measured value of the internal temperature of the diffusion furnace 1 heated by a heater 2 and an in-furnace temperature set value. A slave controller 11 generates a slave controller output PN2 for heater operation on the basis of the difference between a measured value of the temperature of the heater 2 and the master controller output PN1. An attenuator 13 is connected between the master controller output PN1 and the input terminal of the slave controller 11, and the master controller output PN1 is attenuated uniformly by the attenuator 13 and then applied to the slave controller 11. An event information detector 16 is preferably connected to the master controller 10 through a PID switch 17 to selectively switch PID constants of the controllers when an event such as expectable disturbance is detected. When the slave controller output PN2 is >=100% or
