Abstract: PURPOSE: To remarkably enhance the electrical contact characteristics of an Ag-Sn oxide type electrical contact material by adding a little Pb to an Ag-Sn alloy optionally together wirth other specified metalo and internally oxidizing the alloy to enable Sn≥4% to be contained.  
     CONSTITUTION: To an Ag-Sn alloy contg. Sn 4W9% is added Pb 0.05W0.5% or further added one or more out of Cu 0.5W5%, Cd 0.2W5%, Mn 0.01W1%, Ni 0.01W1% and Mg 0.01W1%. This alloy is then heated in an oxidizing atmosphere to diffuse 0 2  in the alloy, thereby converting the metals other than Ag into oxides. At this time, the Pb added in an amt. of 0.05W0.5% remarkably facilitates the 0 2  diffusion to enable Sn≥4% to be contained, resulting in enhanced electrical contact characteristics. In addn., the metals such as Cu uniformly disperse as oxides in the Ag to enhance the characteristics.

Title: Linear motion mechanism
Inventor: UENO YASUO
IPC: F16H21/44
Filed: 1989-01-31
Abstract: PURPOSE:To simplify a structure decreasing sliding resistance while preventing an influence of the gravity from being easily received by an attitude changed by allowing a motion member to perform a linear motion on a line, in which a motion plane of mutual supporting mechanisms crosses with each other, while a balance weight to move in an almost reverse direction to the motion member. CONSTITUTION:A motion member 18 rotates around axes 2, 3 arms 6, 7 moving their other ends in a direction at a right angle with the motion direction of a linear motion part O1 of the motion member 18 in an arrow head, and arms 12, 13 rotate around axes 8, 9. Thus because another ends 14, 15 of the arms 12, 13 move in the motion direction of the linear motion part O1, the motion member is supported so that its motion is permitted in two planes at a right angle respectively with the axes 2, 3. However, because the axes 14, 15 are fixed to the motion member 18 through bearings 16, 17, as the result, the motion member 18 makes a motion on a line, where the two planes are crossed, that is, straight line. While by rotating the arms 12, 13 about the axes 8, 9, weights 43, 44, mounted to levers 41, 42, are moved in a reverse direction to the motion member 18, and it is prevented from dropping by an influence of the gravity because the axes 8, 9 are balanced.

Title: Method for filling through hole with conductive paste
Inventor: OYAMA NOBUHIDE
IPC: H05K3/40
Filed: 1991-02-15
Abstract: PURPOSE:To prevent the enclosure of air in though holes formed through a green sheet when the through holes are filled up with conductive paste by sticking permeable a member to one surface of the green sheet and filling the through hole with the conductive paste from the opened side of the through holes on the other surface of the green sheet by a printing method. CONSTITUTION:The through holes 2 formed through a green sheet 1 are filled up with conductive paste 6 in such a way that, after a permeable member 4 is stuck to the rear surface of the sheet 1, the sheet 1 is placed on the stage 3 of a printing machine with the member 4 on the down side and the hole 2 are filled up with the paste 6 by means of a squeegee 7 through a stainless steel screen 5 having a prescribed through hole pattern so as to prevent the adhesion of the paste 6 to undesired parts on the surface of the green sheet 1. Therefore, the through holes 2 are completely filled up with the conductive paste 6, since the air in the holes 2 goes out of the holes 2 through the permeable member 4 when the holes 2 are filled up with the paste from the opened side (surface side).
