Abstract: The present invention is a conductive adhesive composition containing pressure sensitive adhesive solids and a plurality of silver-coated spheres. The spheres are distributed throughout the composition in a packing configuration which yields a conductive network of adjacent silver surfaces. The composition demonstrates both good cohesive strength-comparable to that of the constituent pressure sensitive adhesive solids taken alone-and good conductivity. Good cohesive strength and conductivity are accomplished by controlling the amount, the average diameter and the particle size distribution of the silver-coated glass spheres in relation to the amount of adhesive solids present in the composition. The composition has utility in a wide variety of industrial and medical applications and is particularly well suited for use in diagnostic procedures such as electro-encephalography and cardiography. A laminated electrode facing incorporating the conductive adhesive is also disclosed.

Abstract: In order to manufacture an IC comprising high electron mobility semiconductor devices, it is necessary to make the carriers in channel layer not to loose their high mobility by thermal treatment during the IC fabrication process. It has been found that the mobility of the two dimensional electron gas (2DEG) is lost by scattering of ionized impurity diffused from doped layer into spacer layer which separates the 2DEG in channel layer from the doped layer. A multilayered structure is proposed including a channel layer (12) made of i-GaAs and formed on a high resistivity GaAs substrate (11), a first spacer layer (13) of undoped Al x Ga 1-x As, a second spacer layer (14) of i-GaAs and a doped layer of n-Al x Ga 1 - x As. The thickness of the second spacer layer (14) is approximately 2 x 10- 9 m, and that of the first spacer is approximately 4x 10 -9 m. A high electron mobility transistor, having such a structure could withstand a heat treatment at 750° C for 10 min. and at more than 950° C for 10 sec. for annealing, the second spacer (14) preventing the diffusion of impurity.

Abstract: A spool (20) for winding thereon a flexible elongate material (36) includes a hollow cylindrical body (21) having an elongate radial opening (23) defined axially in the annular peripheral wall of the spool body for providing a passage of a holding means for automatically holding a leading end of the elongate material on the spool body (21). A winding apparatus (35) includes a pair of oppositely disposed first and second drive shafts (37,38) for holding the spool (20) therebetween. The holding means is associated with the first drive shaft (37) and cooperative with the radial opening (23) in the spool body (21) in effecting the holding of the leading end (36a). The holding means is either the pnumatic type or the mechanical type. The pnumatic holder means produces a negative pressure in the axial hole (22) in the spool body (21) to create a suction force acting around the radial opening (23) in the spool body (21). Due to the negative pressure thus produced, the leading end (36a) of the elongate material (36) is sucked toward the radial opening (23) and then adhered to the annular wall (24) of the spool body (21).
