Title: Control apparatus for oxygen sensor heater
Inventor: SUZUKI MAKOTO
IPC: G01N27/409
Filed: 1989-04-24
Abstract: PURPOSE:To detect oxygen concentration accurately by providing a heater-power controlling means which controls power supplied to a heater so that the power is increased to a higher value than the lower limit value when the detected power supplied to the heater is less than the lower limit value of the power. CONSTITUTION:Power PW which is supplied to an oxygen sensor OS is controlled so that the resistance value RH of a heater HT in the sensor OS becomes a specified value RT. When the power PW supplied to the heater HT which is detected with a heater-power detecting means M1 is less than a lower limit value PO, the power PW is controlled so that the power PW supplied to the heater HT becomes higher than the value PO with a heater- power controlling means M4. The lower limit value of the power PO is determined in correspondence with the operating state which is detected with an operating-state detecting means M2. Namely, the PO is determined in consideration of the power value where the temperature of the sensor OS becomes too low to expect the normal operation of the sensor OS when the power PW supplied to the heater becomes lower than the value PO under the operating state.

Title: Liquid crystal optical switch
Inventor: KASAHARA KUMIO
IPC: G02F1/31
Filed: 1985-05-16
Abstract: PURPOSE:To compensate the temperature dependency of the double refraction of liquid crystal by that of the thickness of a liquid crystal layer and to reduce the temperature dependency of crosstalk by opening the one end surface of a liquid crystal cell from a substrate in space. CONSTITUTION:A rectangular prism 18 fitted to one end surface of the liquid crytal cell 17 can be moved independently of the substrate 19, so that when the cell 17 sealed with d=2.8mum thickness at 20 deg. peripheral temperature is raised up to 50 deg. peripheral temperature, the change of the thickness becomes 5X10<-2>, increasing 5% thickness. On the other hand, the double refraction of the liquid crystal are 0.121 and 0.115 at 20 deg. and 50 deg. peripheral temperatures respectively, reducing 5% double refraction. Therefore, the increase of the depth (d) and the reduction of double refraction are offset each other, so that the temperature dependency of double refraction of the liquid crystal is removed and the increase of crosstalk due to the temperature change can be reduced.

Abstract: PROBLEM TO BE SOLVED: To improve the safety of operation and to reduce cost by refining steel in an electric furnace at a specified blending ratio of pig iron and adding a reducing agent into the furnace when it is judged that the T.Fe quantity in slag is excessive by a specified quantity and in the oxidizing refining period of the carbon concentration in a specified steel bath to prevent bumping. SOLUTION: In the case of refining steel in an electric furnace at the blending ratio of pig iron of >=20%, a reducing agent is added into the furnace to take an action to mitigate the peroxidized condition of slag when it is judged that the carbon concentration [C] in a steel bath is in the oxidizing refining period of >=0.20, specifically, about 0.25-1.00 and the T.Fe quantity in the slag is excessive by >=10 compared with the quantity in a regular oxidizing condition. As the reducing agent, powder coke, metallic Al, Al ash, Fe-Si alloy and Fe-Mn alloy are used, and charged into the furnace, in particular, into the slag. The charging quantity is made to the degree that the T.Fe in the slag becomes an approximately normal value.  The hot metal is prevented from being explosively reacted with the slag to generate bumping without the reduction of the operational efficiency or the increase of the equipment cost.
