Abstract:
A manufacturing method of an anode body of a solid electrolytic capacitor which, for improving the embedded strength of the anode lead with reduced leakage current, successively throws two kinds of valve action metallic powders with different melting-down properties into a single-step press manufacturing die so as to be arranged with the valve action metallic powder whose melting-down property is larger in the neighborhood of the embedded surface of the anode lead.
Abstract:
Cathode and anode sides of a plurality of solid electrolytic capacitors are connected by simultaneous electric welding. The welding step is effected to connect an anode lead of a lead frame to the anode electrode of a capacitor body and simultaneously connect a cathode lead of the lead frame to the cathode conductor layer of an adjacent capacitor body. The welding electrode for the cathode lead exerts moderate force to the capacitor bodies using a spring function of the capacitor lead. The simultaneous welding for the adjacent capacitor bodies and the moderate force prevent electrical and mechanical damages of the insulator layer of the solid electrolytic capacitors during the welding.
Abstract:
A DRAM includes an internal boosting circuit, a global power-line, a plurality of blocks, a row decoder, and a POR generating circuit. Each block includes word lines, local power-lines, AND gates, drive transistors, and word line drivers. The AND gate turns a corresponding drive transistor on/off in response to a power on reset signal /POR and a corresponding block select signal. Therefore, all the local boosted power-lines are connected to the global boosted power-line during a power on reset period, whereby all the local boosted power-lines are initially charged up to boosted power supply potential Vpp.

The levels of the FM audio signals in the first and second mixed audio and video signals are desirably varied upon changes in the level of the audio signal to be recorded.

Abstract:
In production of electrode paste, powder and solvent are separately injected into a hollow exterior component, the powder and the solvent are transferred to a downstream side in a transfer direction by rotation of two rotary shafts supported by the exterior component in a state where the rotary shafts are located parallel to each other at a predetermined interval, a mixture is produced by mixing the powder and the solvent by rotation of the rotary shafts without applying a shearing force, which is higher than or equal to a predetermined shearing force, to the powder, and producing electrode paste by kneading the mixture through application of a shearing force, which is higher than the shearing force that is applied in the mixing step, to the mixture through rotation of the rotary shafts.
