Title: Setting of emissivity of radiation thermometer for continuous heat treating furnace
Inventor: DOI KATSUHIKO
IPC: G01J5/00
Filed: 1987-03-02
Abstract: PURPOSE:To improve temperature measuring accuracy by dynamically setting the emissivity of a radiation thermometer in accordance with change in an operating condition with the overall heat transfer coefficient of a heat treating furnace obtained from a specific condition by using the temperature of a metal strip measured by the radiation thermometer as a reference. CONSTITUTION:The overall heat transfer coefficient phiCG of a furnace is obtained from a relationship represented by the accompanying expression I by using the temperature TSM of a metal strip 5 indicated by a radiation thermometer 6. When the overall heat transfer coefficient phiCG is equal to an empirically or experimentally determined one, an emissivity epsilon1 set in advance is correct and the temperature TSM of the metal strip 5 represents a correct value. The temperature TS1 of the metal strip 5 is calculated by using the set atmospheric temperature TGO and the overall heat transfer coefficient phiCG of the furnace and an LSD. At this time, the emissivity of the radiation thermometer is changed from epsilon1 to epsilon2 so that the temperature TS1 is made equal to the temperature TSM of the metal strip measured by the radiation thermometer. Thus, temperature measuring accuracy can be improved.

Abstract: PURPOSE: To produce a steel material excellent in seawater corrosion resistance as well as in toughness in a weld heat-affected zone by rolling a steel, containing specific amounts of C, Si, Mn, Al, Cr, Ti, N, and Fe, under specific conditions. CONSTITUTION: A steel, having a composition consisting of, by weight, <=0.1% C, 0.1-0.8% Si, <=1.5% Mn, 0.005-0.05% Al, 1-3% Cr, 0.005-0.03% Ti, 0.002-0.012% Ni, and the balance essentially Fe, is used. This steel is heated to 950-1250 deg.C and rolled under the conditions of >=30% cumulative rolling reduction at <=950 deg.C and 650-850 deg.C rolling finishing temp. When the steel is heated to >1250 deg.C, γ-grains become remarkably coarse. When cumulative rolling reduction is <30%, the elongation of γ-structure becomes insufficient and fine ferrite cannot be formed. When rolling finishing temp. is >850 deg.C, fine ferrite grains cannot be formed, and on the other hand, when it is <650 deg.C, rolling becomes that in two phase region and toughness at low temp. becomes deteriorated.

Title: Oscillator circuit
Inventor: SHIMIZU TSUKASA
IPC: H01G4/12
Filed: 1978-04-18
Abstract: PURPOSE: To ensure the high-accuracy and high-stability oscillation by reducing the thermal hysterosis of the frequency-temperature characteristics correcting capacity of the conventional piezoelectric oscillator and thus reducing more the frequency-temperature dependency as the oscillator circuit.  
     CONSTITUTION: The electrostatic capacity featuring the hysteresis is inserted to the oscillator circuit to correct the frequency-temperature characteristics of the X-cut crystal oscillator. In this instant, the frequency-temperature characteristics also features the hysteresis as the oscillator circuit. The rare-earth oxide is added to the capacitor material of a high inductance to reduce the grain growth. Thus, the crystal grain diameter is miniaturized with the domain orientation velocity accelerated. As a result, the thermal hysteresis of the capacity is reduced to obtain the high- accuracy and high-stability oscillation. In case the capacity of thermal hysteresis of under 5% is required, the rare-earth oxide of more than 0.05wt% must be added into the composition.
