Patent JP-H03210466-A (JP)
Title: Apparatus for measuring conductivity
Inventor: MORI TAKESHI
IPC: G01N27/06
Filed: 1990-01-14
Abstract: PURPOSE:To detect peeling of plating and to perform measurement with high accuracy by applying AC voltages having mutually different frequencies across the electrodes immersed in a solution and emitting an alarm or performing correction on the basis of the deviation value of the conductivities at that time. CONSTITUTION:AC voltages having mutually different frequencies are applied across the electrodes 3, 4 immersed in a solution to measure conductivities at the respective frequencies and, when the deviation between them exceeds a predetermined reference value, a predetermined alarm is emitted. By this method, the release of the plating of the electrodes 3, 4 can be detected during measurement. When the deviation is the predetermined reference value or less, a polarization capacity value is calculated by a predetermined polarization capacity formula to be stored and polarization is corrected on the basis of a polarization correction formula.

Title: Pipe with protrusion
Inventor: YAMAGATA YASUO
IPC: F28F1/36
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To enable preventing of wear-out breakage because of contact with a support metal while improving heat transfer performance by forming a plurality of protrusions made slender and linear or spiral with a circular or semi-circular section along the length of the external surface of a pipe. SOLUTION: Four linear protrusions 2 are formed at an interval of 90 deg. in the circumferential direction on the external surface along the length of a heat exchanger tube 1 and heat transfer surfaces 3 sandwiched between the protrusions 2 are formed. The linear protrusions 2 are made semicircular and the height of the protrusion 2 is determined by a relationship with the total intensity of the heat exchanger tube 1 considering its role of reinforcing the strength of the heat exchanger tube 1. The existence of the protrusion 2 on the surface of the heat exchanger tube 1 keeps a heat transfer surface 3 from directly contacting a support metal and causing wearing thereof thereby allowing reduction in the thickness of the heat transfer surface 3. This achieves higher heat transfer performance and can prevent wear-out breakage under contact with the support metal.
