Title: Carbon dioxide sensor
Inventor: ISHIGURO YOSHIAKI
IPC: G01N27/18
Filed: 1985-08-23
Abstract: PURPOSE:To obtain a carbon dioxide sensor which can detect carbon dioxide easily and selectively with relatively high sensitivity by coating crystalline alumino silicate having an Al/Si atomic ratio of a prescribed value or above on a platinum coil. CONSTITUTION:The crystalline alumino silicate having 1-50 Al/Si atomic ratio is coated on the platinum coil 3 to form a bridge circuit of spherical catalyst 4. One thereof is used as a reference element and the other one as a detecting element. Electric current is passed to the coil 3 to heat the surface of the catalyst 4 to 200-600 deg.C. The resistance of the coil 3 increases when the carbon dioxide is adsorbed on the sensor surface. The carbon dioxide is thus detected.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of supplying power by greatly shortening the failure lasting time or voltage drop time of a perfect circuit even if a failure occurs at any portion of a distribution system and to attempt to minimize the damage to the failed portion caused by arcs or to reduce pressure rise by the arc inside a distribution device. SOLUTION: Current detectors 11, 12a to 12c, 13a to 13c are arranged at the secondary side of a main switch 1 and branch switches 2a to 2c, 3a to 3c to feed each detected output to a failure determining and controlling device 42. When a failure such as a short circuit causes a current of a set value or more to flow in a given branch switch, this controlling device 42 immediately sends a contact parting command to the main switch 1 to break the current by making it part the contacts. Right after this, the contact parting command is sent to a branch switch directly above a portion, where a failure occurred to open its electric circuit by making it part the contacts. Then, the contacts of the main switch 1 are closed again. Switches having a short working response time (contact parting and closing times) are used as the main and branch switches.
