Title: Method and device for detecting heat flux of mold for casting
Inventor: OKUMURA HARUHIKO
IPC: G01K17/08
Filed: 1992-05-15
Abstract: PURPOSE:To detect the heat flux flowing to the thickness direction of a wall part, by inserting in a hole of the mold wall part a sensor in which a metal of a different kind is joined to an end of a metal bar of the same material as a mold for casting, and by connecting the metal piece of the different kind to the hole bottom. CONSTITUTION:A sensor 11 comprises a metal bar 12 of the same material as a mold M and a metal piece 13 of a different kind secured to an end thereof and is inserted in a hole 14 made from the outside of a mold wall part W to the thickness direction, and the piece 13 is joined to the bottom of the hole 14. Thermocouples are constructed by the wall part W to the metal piece 13, and the piece 13 to the metal bar 12 respectively, and consequently a differential thermocouple is formed. Therefore, since electromotive force detected by an electromotive detecting means 26 is measured as the difference of the electromotive forces of two contacts (both sides of the metal piece 13), the temperature difference thereof can be detected. The heat flux flowing within the sensor 11 is found from a prescribed equation by using the temperature difference. The heat flux of a point to be measured within the wall part W can be detected, because the measured value of the heat flow is proportioned to the heat flux within the wall part W.

Title: Image sensor
Inventor: KONNO RYOICHI
IPC: H04N5/335
Filed: 1987-06-16
Abstract: PURPOSE:To obtain an accurate gradation output with less influence of noise even for an input close to black level (density is large) by constituting the titled sensor whether the sensor itself is a voltage variable type capacitor in construction or a voltage variable type capacitor is connected in parallel with the sensor, in the charge storage type image sensor. CONSTITUTION:As for the electrical equivalent circuit of an image sensor 3, a resistor R varies depending on the quantity of light while a capacitor C does not vary in a conventional sensor. Therefore, the relation between the quantity of incident light and that of an output goes to linear. Hence the current dis charged from the capacitor C running through the resistor R is reactive to the quantity of light linearly without depending on the voltage. In this invention, the capacitor C or a capacitor connected in parallel with this C is made of voltage sensitive type to improve the S/N of the sensor. By producing the image sensor so that the capacitor C goes to voltage sensitive type or by connecting such kind of element in parallel connection, it is provided that the voltage across the capacitor C drops because the discharge enhances in case the quantity of light is large (white density) hence the capacitance becomes larger. In case of black level, the effect is reverse.
