Inventor: YAKABE HISATAKA
IPC: H02N10/00
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a conversion method for generating electric power by using a temperature difference between a combustion area and an air supply pipe peripheral wall surface, by arranging a thermoelectric conversion element on the outer periphery or an inner peripheral wall surface of an air supply pipe in the combustion area of a cylindrical solid electrolyte fuel cell, and generating electric power by using combustion heat through unreacted fuel and surplus air at fuel cell operating time. SOLUTION: Air supplied to an air supply pipe is supplied to a solid electrolyte in a cell by turning back from a lower end part of an inner tube to react with hydrogen supplied through the outer wall of the cell to generate electric power. At this time, surplus air and unreacted hydrogen burn in a combustion area by passing through clearance between the outer periphery of the cell and a lower partition wall. The combustion area is also at a high temperature, similar to a cell temperature at power generation operation time, the temperature difference is generated between the temperature and an outer wall temperature of the air supply pipe, and a temperature difference ΔT when supplying air at the normal temperature depends on a condition such as a place and a fuel utilization factor, but becomes, for example, 600 to 900 deg.C.  Additionally, electric power from a cylindrical solid electrolyte fuel cell, electric power is obtained by using the temperature difference by a thermoelectric converting element arranged on an air supply pipe outer wall surface.

Title: Grounding method and ground resistance reducing method
Inventor: SAKANE TETSUSHI
IPC: H01R4/66
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To rapidly install a ground and reduce the ground resistance below a reference value by changing the buried depth in the cases grounding is newly made or by enlarging the area of injection of a resistance reducing agent in the cases of an existing one. SOLUTION: A hole is drilled in a pavement base and the subsoil by a hammer drill, and a grounding rod 5 mounted with a harpoon 55 on an end thereof is sunk in the hole. The grounding rod 5 is sunk deeper by bitting with a hammer drill to reduce the ground resistance. The pavement base is restored by being back filled, compacted with a computer mounted on the hammer drill, and filled with a seal material. Because processes for drilling, sinking, and compacting, are accomplished only with a drilling tool such as a hammer drill, grounding can be quickly performed by a single worker without needing any other installations.  A sealing member 7 is inserted into the ground rod, the sealing member is forced in downward, a resistance reducing agent packed around the grounding rod is thereby pressed to penetrate the subsoil, the penetration area of the resistance reducing agent is thereby enlarged, and thus the ground resistance is reduced.
