Title: Abnormal cooling temperature sensing method in power transmission
Inventor: HATTORI HITOSHI
IPC: H01B12/16
Filed: 1987-10-27
Abstract: PURPOSE:To sense abnormality in the cooling temp. and incapability of cooling due to coolant leakage, etc., by arranging superconductors A, B with critical temps. TA, TB under a specific temp. relation while pinching a cooling material whose cooling temp. is T0. CONSTITUTION:With a cooling material 4 of cooling temp. T0 pinched, a superconductor A8 with critical temp. TA contributing to actual power transmission line and another superconductor B9 with critical temp. TB are arranged under the temp. relation TA>TB>=T0. When a voltage V0 is impressed between two points on the superconductor B by the power supply 11, the voltage drop at both ends of a resistance R becomes V0 while the superconductor B is indicating superconductive phenomenon. When superconductive phenomenon is no longer indicated, a small resistance is generated on B to cause voltage drop, so that the voltage drop V1 at both ends of R becomes smaller than V0. Thus abnormal cooling temp. can be sensed thereby it.

Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To enhance the thermal efficiency of an absorption refrigerating apparatus while preventing the overheating of a engine resulting from a rise in the temperature of cooling water. SOLUTION: A regenerator 2 is a doubly effect type provided with a high temperature regenerator 2 and a low temperature regenerator 4. The low temperature regenerator 4 is provided with a fourth pipeline K4 which passes a weak solution. An upstream fifth pipeline K5a where cooling water (about 80 deg.C) of an engine flows on the upstream side, is provided outside the fourth pipeline K4 while a downstream fifth pipeline K5, where a high temperature exhaust gas of the engine 1 flows, is provided on the downstream side. Therefore, the weak solution which flows in the third pipeline K3 is heated with cooling water on the upstream side and then heated with a high temperature exhaust gas. As described above, the weak solution is heated with the cooling water, and then heated with the exhaust gas so that a large volume of steam may be generated, thereby enhancing thermal efficiency.  Since the temperature of cooling water fails to rise with the heat of exhaust gas, it is possible to prevent the overheating of the engine 1.
