Title: Manufacture of ceramic multilayer interconnection board
Inventor: YAMADA TOMOHIRO
IPC: H05K3/46
Filed: 1988-03-31
Abstract: PURPOSE:To prevent an iron metal layer and a high melting point metal conductor layer from being oxidized by a method wherein a conductive paste layer containing at least one or more of copper, nickel or cobalt as its main component and added a reducing agent of silicon, boron, or a compound consisting of these elements is provided between the iron metal layer and a thick film conductor layer. CONSTITUTION:A conductive paste layer 16' containing copper, cobalt or nickel as its main component and containing a reducing agent is subjected to screen printing on an iron plated layer and moreover, a thick film conductive paste layer 17' containing a base metal, such as copper, as its main component is formed on both of the layer 16' and an insulating layer 14 by printing into a necessary circuit pattern and thereafter, the layer 17' is fired in an atmosphere containing such inert gas as nitrogen gas to obtain an oxidation-resistant protective layer 16 and a thick film conductor layer 17. In case silicon, for example, is used as the reducing agent, its content is set in 1.5-3.0wt.% or thereabout and in case manganese boride is used, its content is set in 1.5-3.0wt.% or thereabout. A simultaneous firing becomes possible by this reducing agent and the iron group metal layer and a high-melting point metal conductor layer 12 are prevented from being oxidized.

Filed: 1993-04-02
Abstract: PURPOSE:To improve residual stresses in an antiabrasion coating of a transition piece and suppress abrasion of engaging portions of a combustor liner and the transition piece by subjecting the antiabrasion coating of the transition piece after use of an actual combustor to shot peening. CONSTITUTION:In repairing a combustor, cracking of a combustor liner is repaired in a first process, and a transition piece is subjected to solution heat treatment in a second process for improvement of weldability and ductility. Cracking of the transition piece is repaired and deformation of the transition piece is corrected in a third process, and the transition piece is again subjected to solution heat treatment in a fourth process for removal of residual stresses in welds and portions, of which deformation is corrected, and homogenizing of the welds and the portions.

Title: Stroke adjustment device for hydraulic stroke device
Inventor: OTA AKINORI
IPC: B25D9/26
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To adjust a stroke according to the change in a state of each stroke by providing a thruster pushing a rod frontward between a stroke device body and the rod and providing a stroke control mechanism changing the stroke of a piston according to the front/rear displacement of the thruster. SOLUTION: Where bedrock is soft, the speed of a rod entering into the bedrock is high, and a breaker body cannot follow the forwarding movement of the rod, a thruster 12 pushes the rod frontward to closely stick it to the bedrock. Then, with the forwarding of the thruster 12, the communication between an operation port 18 and a return port 19 are interfered so that pressure oil is leaked from a high-pressure thrust chamber 20 to the operation port 18. The pressure oil gradually actuates a stroke control valve 42 to an open side via an operation circuit 17. As a result, a short stroke port 27 and a valve control chamber 75 are communicated with each other via a stroke control circuit 13 so that the control valve chamber 75 becomes high pressure to retreat a valve element 74 of a control valve 70. This constitution can shorten the stroke of a piston 1.
