Title: Multiwavelength spectrophotometer
Inventor: OKUDA MINORU
IPC: G01J3/36
Filed: 1993-04-21
Abstract: PURPOSE:To enhance SN ratio by setting the integration time of each element in a multichannel photodetector such that the each element can produce a substantially equal integration output thereby ensuring a sufficient integration time at a part where the optical intensity of spectrum is low while preventing saturation of the integration output at a part where the optical intensity of spectrum is high. CONSTITUTION:A spectroscopic element 5 projects a spectral image on the light receiving plane of a photodetector 6. A controller/data processor 7 controls the entire system and performs data processing whereas a display 8 presents spectral measurement results and the like. The data processor 7 opens or closes a shutter 3 to control exposure of the photodetector 6 and designates the address of each element in the photodetector 6, reads out the output from an addressed element thus performing data processing. Integration time is then set such that the higher the intensity of light on a spectrum to be measured the shorter the integration time. This constitution enhances S/N ratio and sensitivity by increasing the integration time at a part where the optical intensity is low while avoiding saturation thus allowing highly accurate measurement of the entire spectrum.

IPC: G05D23/19
Filed: 1983-06-30
Abstract: PURPOSE:To prevent transient control disturbance by comparing a position type temperature regulating signal of a temperature controller for a heating surface or the like with a thermal source supply signal, outputting a larger value signal with priority and correcting the value of a velocity type temperature regulating signal corresponding to the output. CONSTITUTION:The position type temperature regulating signal fs being an output of the signal converter 13 and a fuel flow rate signal fF being an output of a fuel flow rate transmitter 2 are applied to a high priority circuit 19, where the amplitudes of the two inputs are compared and a signal having a larger amplitude is outputted with priority. When the relation of fs=fF exists between the signals fs and fF at the steady-state, the circuit 19 applies a signal of fc=fs=fF to a function generating circuit 14 so as to keep the loop gain nearly to a constant value. If a load is increased suddenly at a time t1, although the signal fs is increased rapidly, since the signal fF is increased slowly, the circuit 19 selects the signal fs and the signal of fc=fs is applied to the circuit 14, allowing to quicken the setting of temperature.

Title: Tool failure sensing device
Inventor: SASAKI KOUBOU
IPC: B23Q17/09
Filed: 1983-06-30
Abstract: PURPOSE:To have automatic sensing of any failure of a machining tool accurately and quickly during cutting operation by determining quantitatively the change of mechanical vibration at the time of normal cutting and any abnormal cutting with tool failure through determination of the ratio of the peak value of vibration to the effective value and mean value. CONSTITUTION:At a tool failure sensing device to detect occurrence of any failure in a machining tool during its cutting operation, a specific alarm level shall previously be set by a variable setting device 9. The setting value is determined on the basis of the output data from a dividing circuit 7 during normal cutting. If this value is represented by CL, a comparator 8 compares the output Cout given by said dividing circuit 7 during cutting with this set value CL, and when Cout exceeds C, the comparator 8 judges that the case is with failure to emit a sensing output so as to lead to actuation of a relay circuit 10. This output Out from the circuit 10 provides alarm, for ex., to inform the operator about occurrence of failure. Thus any failure in a tool can be automatically sensed accurately.
