Filed: 1989-08-22
Abstract: PURPOSE:To obtain a green sheet excellent in transfer property by a method wherein internal electrodes and a dielectric layer covering the internal electrodes are formed on a base film to be a supporting body while water soluble binder is contained. CONSTITUTION:Internal electrodes and a dielectric layer 2 covering the internal electrodes are provided on a base film 4 to be a body for supporting green sheet structure, while water soluble binder is contained on the surface of a green sheet or in the dielectric layer 2.

Abstract: PURPOSE:To secure a high reliability of breaking performance and insulation performance by providing an arc resistant metal at a main contact opening point for an opening time and a range around it, and energizing conductor parts for contact parts except for the arc resistant metal in a complete closure condition. CONSTITUTION:For opening operation, a main contact is opened at its opening point Q, when load current at the main contact moves to the arc contact side to produce a main contact arc at the opening point Q because a resistance 33 is connected in series with a fixed side arc contact 29 to set the impedance at the part. The opening point Q is positioned at the center of an arc resistant metal 34, 35 both on the finger 25 side and the movable contact 17 side, so damage is slight if the arc is produced. By further opening after this, arc contacts 28, 29 gets apart from each other, and because the load current is reduced by the resistance 33, breaking current is small, and breaking can be achieved easily and in a short arc time.
