Title: Method and apparatus for measuring concentration of silicon in fused iron
Inventor: HAIDA OSAMU
IPC: G01N25/00
Filed: 1984-08-20
Abstract: PURPOSE:To measure the concentration of silicon in a short time, by measuring thermoelectromotive force accompanied by the temperature difference caused by the difference in places of samples during the cooling process, after fused iron, which is inputted in a sample container, is solidified. CONSTITUTION:A sample container 1 is composed of fire resisting shell mold, electrodes (copper rings) 2 and 3 and a temperature measuring thermocouple 4. Of an iron sample, a part contacting the electrode 3 is close to the end part, whose diameter is small. The cooling speed of said part is higher than that of a part contacting the electrode 2, which is provided at the central part. Therefore, the temperature difference is yielded between the surface of the iron contacting the electrode 2 and the surface of the iron contacting the electrode 3. Electromotive force is generated between both electrodes. The concentration of silicon in the fused iron is obtained based on the electromotive force and the calibration curve of the concentration of the silicon.

IPC: G03B7/085
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To make switching operation of diaphragm blades stable while reducing the power consumption in a steady-state. SOLUTION: An image pickup element 14 outputs an image signal corresponding to an optical image that is made incident through a photographing lens 10 and diaphragm blades 12. The output of the image pickup element 14 is given to a process circuit 20 via a CDS/AGC circuit 16 and an A/D converter 18. The circuit 20 converts the output of the A/D converter 18 into video data such as the NTSC data. A microcomputer 32 applies a control signal, which decreases a luminance level when the luminance level of the photographing picture is too high and increases the luminance level when the luminance level of the photographing picture is too low, to an iris drive control circuit 30. The circuit 30 generates a drive control voltage to an IG meter 24 according to this control signal and a chopper circuit 32 applies pulse width modulation to the voltage signal.  The output of the chopper circuit 32 controls switching of a switching element 34. When the switching element 34 is closed, a voltage is applied to the IG meter 24. An iris encoder 28 detects a rotational position of the IG meter 24 from the output of a Hall element 26 and gives the detected signal to the circuit 30 and the microcomputer 32.

Abstract: PURPOSE:To realize a wide-band, stable signal selecting circuit which has excellent output linearity by composing the circuit of transistors (TR), current sources, and resistances. CONSTITUTION:For example, input signals of circuit blocks S1 and S2 have voltage values so that V1>V2. The emitter current of an output TR Q23 is larger than the emitter current of an output TR Q13. The collector current of a TR Q14 increases and its collector voltage drops; and a clamp TR Q15 is turned on and a feedback TR Q13, on the other hand, is biased reversely to turn off. An input TR Q11 is held on. The collector current of a TR Q24, on the other hand, decreases and its collector voltage rises; and a clamp TR Q25 is biased reversely to turn off and a feedback TR Q22 is turned on and enters a balanced state when the base voltages of the output TRs 13 and 23 are nearly equal to each other. Consequently, an input TR Q21 is turned on and only an input signal V1 appears at an output terminal O.
