IPC: A23B4/03
Filed: 1981-03-13
Abstract: PURPOSE: To obtain a smoked product having excellent preservability, by repeating the drying step and the smoking step alternately at preset time intervals, wherein the smoking treatment is carried out in a closed state stopping the ventilation while the drying step is performed introducing the fresh air.  
     CONSTITUTION: The raw material is placed in a thermostatic chamber 1, the shutter 3 is set to the state of the drying operation, and the heater 13 is electrified to start the drying treatment. Since the air inlet 4 and the outlet 5 are in the opened position, the water evaporated from the raw material is accompanied with the fresh air and exhausted from the chamber. After the predetermined time, the shutter 3 is changed to the state of the smoking and drying operation, and the heater 7 is electrified. Since the air inlet 4 and outlet 5 are shut to close the chamber, the smoke generated in the smoking chamber 2 is introduced through the opening 8 into the thermostatic chamber 1, and diffused in the chamber by the agitating action of the fan 14. After a predetermined time, the step is changed to the drying step, and the above process is repeated.

Title: Standardizing method for spectroscope apparatus and spectroscope apparatus
Inventor: ARAN EMU GANZU
IPC: G01J3/28
Filed: 1993-02-03
Abstract: PURPOSE: To obtain spectral machinery equipped with a novel means for bringing about standardized spectrum data. CONSTITUTION: Spectral machinery 10 showing inherent appearance in relation to a sharp spectrum line generates appearance data in relation to a narrow spectrum line. The spectrum line is brought about by high finess etalons 46, 48, 50 composed of a gold coated polymer. A conversion filter is calculated in order to convert appearance data to Gauss appearance. A wavelength calibrator is connected to a filter in order to bring about the correction matrix applied to sample data for generating calibrated standardized data. The correction matrix is repeatedly applied to calibration data in order to generate standardized calibration data utilized in the calibration of a wavelength. Calibration is performed by an optical standard, an interference etalon and a strip formula.  Etalon effective thickness is evaluated at first and a stripe peak is subsequently precisely determined so as to calibrate a wavelength.
