Abstract: PROBLEM TO BE SOLVED: To prevent the generation of tin whisker from a lead line part, and to prevent the increase of leakage currents or the occurrence of short circuit. SOLUTION: Tin plating containing bismuth which is 0.5-10.0 wt.% is operated to the surface of a lead line 8 constituted of a CP line so that a bismuth tin layer 10 can be formed. Afterwards, this leading line 8 is welded to a round bar part 6 of a tab terminal constituted of the round bar part 6 and a flat part 7 so that lead lines 4 and 5 can be formed. When welded, the bismuth tin layer 10 is melted so that bismuth can be contained in a welding part 9. The flat parts 7 of the lead lines 4 and 5 are respectively connected with an anode electrode foil 2 and a cathode electrode foil 3, and those electrode foils 2 and 3 are wound through a separator 11 so that a capacitor element 1 can be prepared.  Electrolytic solution is immersed in the capacitor element 1, and the lead lines 4 and 5 are inserted into the hole part of a sealing body 12, and the capacitor element 1 is housed in a cylindrical armor case 13 having a bottom. Then, the end part of the opening of the armor case 13 is sealed and this electrolytic capacitor is completed.

Title: Formation of conductive circuit
Inventor: TOMITA SATORU
IPC: G03G21/00
Filed: 1980-12-16
Abstract: PURPOSE:To form a stable conductive circuit wherein contact resistance does not fluctuate by energizing a pair of non-magnetic conductive materials in mutually press contacting directions by means of a magnetic means such as magnet. CONSTITUTION:A belt-like photoreceptor 1 consists of a photocondictive layer 11 in the uppermost position, a conductive layer which is the 1st conductive member in an intermediate position, and an insulating layer 15 called base layer in the lowermost position. When the photoreceptor 1 is turned by a driving roller 2, the roller 17 in contact with the layer 13 is driven together with a sleeve 19; moreover, the attraction effect by magnetic force is generated between a magnet 21 and a driven roller 3, by which the sleeve 19 is moved to the roller 3 and therefore the contact pressure between the roller 17 and the layer 3 is increased and the roller 17 increases its contact area easily because it has flexibility. Thereby, the stable conductive circuit wherein contact resistance does not  change is formed.

Abstract: PURPOSE:To enable black and white display with an excellent time sharing characteristic by disposing a double refracting member which provides a double refracting effect to one face by utilizing the double refracting effect of a liquid crystal cell formed with the twisted spiral structure within the range of specific angles. CONSTITUTION:A pair of upper and lower electrode substrates 11 and 12 which are subjected to an orientation treatment are disposed to face each other apart at a spacing d1, then the electrode substrates 11, 12 are adhered. A nematic liquid crystal having positive dielectric anisotropy is sealed into the spacing therebetween. The liquid crystal molecules are arranged to the spiral structure in which the twist angle theta is twisted 200-300 deg. in the thickness direction between the electrode substrates. The double refracting member 40 having the double refracting effect is disposed on the upper side of the substrate 11 of the liquid crystal cell 60 constituted in such a manner. Upper and lower polarizing plates 15, 16 are provided on both sides of the member 40 and the cell 60 in-between. The member 40 acts to modulate the polarization state of the light transmitted through the cell 60, thereby converting the display which is heretofore made only in colors with the cell 60 alone to the black and white display. The color display is, therefore, possible as well.
