Title: Polarization modulating infrared spectroscopic device
Inventor: TOCHIGI KENJI
IPC: G01N21/71
Filed: 1989-04-19
Abstract: PURPOSE:To make measurement with a good sensitivity by providing means for changing the optical path difference of an interference spectroscope to a step shape and removing the disturbance of background light from the IR emission spectra of a thin-film sample. CONSTITUTION:IR emitted light rays 4, 4' are generated from a substrate 2 and the thin-film sample 3 heated by a heater 1. Of the IR emitted light rays, the rays based on the molecular oscillation of the sample 3 have linear polarization characteristics by the multiple reflections and interferences between the thin-film boundaries. The ray 4 emitted from the substrate 2 based on the black body radiation does not have the polarization characteristic. The ray 4 enters an elastic modulating element 6 which rotates the plane of linear polarization according to an impressed voltage, via a mirror 5, thus receiving the modulation of the intensity proportional to the frequency twice the sine wave signal 8 of the frequency from an oscillator 7. The ray 4' generated from the substrate 2 has no polarization characteristic and is, therefore, not subjected to the modulation of the intensity. Further, the rays 4, 4' transmitted through the element 6 are collimated to collimated beams of light via mirrors 9, 10 and thereafter, the beams are bisected by a beam splitter 11 and are made incident to a stationary mirror 12 and a movable mirror 13, by which the reflected interferences are generated. The interfered rays 4, 4' are condensed by a mirror 14 and are photodetected 15.

Then, the box body 15 is moved and at a next pipe hole 9, the same operation is repreated. This mechanism inserts heat-conductive pipes 34 into pipe holes 9 precisely and also automates pipe inserting operation.

Inventor: IGAKI YOSHIHIRO
IPC: G01K7/00
Filed: 1985-05-08
Abstract: PURPOSE:To perform extremely accurate temperature measurement, by inputting an electric pulse from the rear edge of a sensor positioned to a point, at which temperature measurement is to be performed, and measuring the temperature of an object to be measured from the degree of inclination of signal waveforms reflecting from the front edge. CONSTITUTION:The front edge section of a conductor sensor 5 whose characteristic impedance is almost constant is positioned to a point, at which temperature measurement is to be performed, of an object 9, whose temperature is to be measured. An electric pulse is inputted from the rear edge of the sensor 5 and the temperature of the object 5 is measured from the degree of inclination of signal waveforms reflecting from the front edge of the sensor 5. When the temperature measurement is performed in such a way, the sensor 5 is always exposed from the surface of the object 9 even when the object 9 is corroded by a high-temperature gas or molten substance and its thickness is reduced from (a0) to (a) and the pattern of the reflecting waveforms makes parallel movement only. Therefore, extremely accurate temperature measurement can be performed.
