Patent JP-S57112069-A (JP)
Title: Integrated circuit
Inventor: UENO KOUJI
IPC: H01L29/73
Filed: 1980-12-29
Abstract: PURPOSE:To make a longitudinal width narrow and obtain highly integrated device such as an IC by a method wherein SBD of a Schottky clamp transistor is positioned perpendicular to the parallel direction of a collector contact, base and emitter independently. CONSTITUTION:A transistor TR to which SBD is clamped as a driver is provided in series to a word line 10 of, for instance, a P-ROM memory IC which consist of a TTL circuit. The electrode 24 of the SBD.TR is positioned, not in parallel direction with each region of the transistor as by conventional method, but perpendicular to the direction independently instead. For instance, the electrode 24 is positioned in the longitudinal direction of the emitter region 23 and the base region 22 including the base contac region 22C and by the side of the collector contact region 21c. With above configuration, the longitudinal width of the SBD.TR which limits the integrity of the cell portion can be narrowed when the memory is composed, so that a highly integrated IC can be obtained.

Title: Manufacture of macro compound material
Inventor: KANTNER ROBERT CAMPBELL
IPC: C22C49/06
Filed: 1990-07-17
Abstract: The present invention relates to a novel process for forming macrocomposite bodies. Particularly, a suitable matrix metal (33), typically in a molten state, is in contact with a suitable mass of filler material or preform (31) located adjacent to, or in contact with, at least one second material in the presence of a suitable reactive atmosphere in an impermeable container (32), at least at some point during the process, which permits a reaction to occur between the reactive atmosphere and the molten matrix metal (33) and/or mass of filler material or preform (31) and/or impermeable container (32), thereby causing molten matrix metal (33) to infiltrate the mass of filler material or preform (31) due to, at least in part, the creation of a self-generated vacuum. Such self-generated vacuum infiltration occurs without the application of any external pressure or vacuum. The molten matrix metal (33) infiltrates the mass of filler material or preform (31) to such an extent that the molten matrix metal (33) contacts at least a portion of the at least one second material. Upon cooling the matrix metal (33) to a temperature below the melting point of the matrix metal, a macrocomposite body is formed comprising a metal matrix composite body bonded to at least a portion of the at least one second material.

Title: Base isolation construction
Inventor: NAKAMURA TAKESHI
IPC: E04F15/18
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To aim at an improvement in base isolation effectiveness by elastically supporting a superstructure in the vertical direction in relation to its downward substructure via a belleville spring in a state of being added with preload pressure, in use of a nonlinear spring domain where a variation in resiliency becomes lessened to a spring deformed variable. SOLUTION: A belleville spring 16 is installed in space between a floor face 12 and a support structure 14 by way of having a vertical pair of spring layered products, where plural pieces of belleville spring simples 16a are superposed in the same sense, butted in the reverse direction. Then, floor load acts on this belleville spring 16 as preload pressure, and in the state intact, the belleville spring 16 is set up in the range of a spring characteristic nonlinear spring domain. This nonlinear spring domain means that its variation in resiliency is small to a prospective variation in vertical clearance size S between the floor face 12 and the support structure 14, and within this domain, the belleville spring 16 basically absorbs a vertical vibration while if it is flexurally deformed, frictional force to be produced among belleville spring simples 16a works as its damping force.  Accordingly, any vibration in the support structure 14 is absorbed as the belleville spring 16 is turned to a cushioning material.
