Abstract: In a terminal member, a protuberance is formed so as to protrude toward an external electrode, and thereby, a bonding portion where the terminal member is bonded to the external electrode, the bonding portion being formed with solder, is extended substantially linearly across a part of the external electrode. Preferably, the direction in which the bonding portion is elongated linearly is in parallel to that in which internal electrodes are extended. Further, it is preferable that the bonding portion is as wide as possible, and the center of the bonding portion in the width direction is as near to the center of the end-face of the capacitor body as possible.

Abstract: Both of the longitudinal dimension L and the widthwise dimension W of a capacitor body are at least four times the thickness-wise dimension T, respectively. Preferably, the widthwise dimension W of the capacitor body 2 is greater than the longitudinal dimension L.

Abstract: A ceramic condenser module includes at least one first multi-layered ceramic condenser and at least one second multi-layered ceramic condenser, which are mounted to a front surface and a back surface of a substrate, respectively. When a total surface area of the outside surfaces of the mounted first and second multi-layered ceramic condensers excluding surfaces thereof opposing the substrate is defined as S2, and a total equal to S2 and a surface area of the outside surface of the substrate excluding the area covered by the first and second multi-layered ceramic condensers is defined as S1, S1 is equal to or greater than about 1.3 times S2. With this arrangement, the ceramic condenser module is suitable for use with large amounts of current, has excellent heat-dissipation effect, is much smaller and much less expensive.

Abstract: A highly reliable method for screening a multi-layer ceramic electronic component, in which multi-layer ceramic electronic components having inner-structural defects and a reduced useful life are efficiently detected and removed. In this method, after applying an AC voltage to a multi-layer ceramic electronic component, a DC voltage is applied thereto. Then, by measuring the insulation-resistance value of the electronic component obtained when the DC voltage is applied, the quality of the multi-layer ceramic electronic component is checked. The applied AC voltage is in a range of 40 to 80% or 50 to 70% of a breakdown voltage. The applied DC voltage is between approximately a rated voltage and approximately twice the rated voltage. This method can, for example, be applied to the screening of a multi-layer ceramic capacitor.

Abstract: A coating layer composed of a solder containing tin as the major component and a metal such as copper or silver which is the same as that contained in a external electrode in an amount greater than the eutectic concentration, is formed on the external electrode. The solder can suppress the solid-phase diffusion without formation of the barrier layer.

Abstract: A high nitrogen flux cored wire contains N and nitrogen compound (total converted value of N): 0.05 to 0.30 wt %, with respect to total weight of the wire, in stainless steel sheath and flux, and TiO.sub.2 : 4.0 to 8.0 wt %; ZrO.sub.2 : 0.5 to 4.0 wt %; SiO.sub.2 : 0.05 to 1.5 wt %; Al.sub.2 O.sub.3 : 0.05 to 1.5 wt %; metal fluoride (converted value of F): 0.02 to 0.7 wt %; and metal carbonate: less than or equal to 1.0 wt %; a content of Al.sub.2 O.sub.3 and SiO.sub.2 in total being restricted to be less than or equal to 2.5 wt %, with respect to total weight of the wire, in the flux. Since an appropriate amount of nitrogen is contained in the wire, superior corrosion resistance of the welded metal can be obtained. Also, since an appropriate amounts of the slag forming agent, alloying component and so forth are contained, it becomes possible to achieve high welding workability in all position welding.

Abstract: A high nitrogen flux cored wire for welding of Cr--Ni type stainless steel is formed by filling a flux into a sheath of stainless steel. The flux is composed of N and nitrogen compound (total converted value of N): 0.05 to 0.30 wt % with respect to total weight of wire, in the sheath and the flux; and TiO.sub.2 : 4.0 to 8.0 wt %, SiO.sub.2 : 0.3 to 3.0 wt %, Al.sub.2 O.sub.3 : 0.05 to 1.5 wt %, metal fluoride (converted value of F): 0.05 to 0.7 wt %, ZrO.sub.2 : less 0.5 wt %, and metal carbonate: less than or equal to 1.0 wt % with respect to total weight of the wire, in said flux.

Abstract: Provided is a stainless-steel flux cored wire electrode with excellent arc stability and good workability with less sputter generation, which can attain the overall sputter reduction and arc stability and can further prevent instantaneous arc disorders and sputter generation at a higher level to form a high-quality weld metal. A stainless-steel flux cored wire electrode comprising a flux filled in the stainless-steel housing at 10 to 30% to the total weight of the wire electrode, wherein the wire electrode temperature is measured and recorded on the recording chart of a temperature recorder, which chart is scaled in such a manner that the 100.degree.

Abstract: An auxiliary propelling structure can be attached to an existing propeller system including a propeller having a boss, a propeller shaft and a tightening nut screwed onto the end of the shaft. The auxiliary propelling structure includes an auxiliary boss that is approximately cylindrical to enclose closely the tightening nut of the existing propeller system and having an internal partition with a central through-hole. The partition is pressed against the tightening nut.
