Title: Preventing method of corrosion of heat exchanging pipe
Inventor: NAGATA KOUJI
IPC: F28F19/00
Filed: 1983-05-18
Abstract: PURPOSE:To effectively prevent corrosion at a pipe end in a heat exchanging pipe in which sea water, etc. is flowed by forming a lapped part by a painted plastic coating on the inner wall of the pipe and a sleeve inserted into the end of the pipe. CONSTITUTION:A heat exchanging pipe 2 made of aluminum brass pipe etc. is applied with a paint coating of a certain plastic paint on the inner wall of the pipe's inner side. Such heat exchanging pipe 2 is expanded in diameter in a predetermined length so as to be fixedly attached to a pipe plate 6 by pressure interference after the pipe end is inserted into an attachment hole in the pipe plate 6. Then, a sleeve 10 made of synthetic resin is inserted into the pipe end with a lap length l of 5-200mm. relative to the paint coating 4, and is fixedly glued to the pipe end with a suitable adhesive. In this manner, the heat exchanging pipe, more particularly its pipe end is effectively protected from corrosion without providing an electrical corrosion prevention device.

Title: Temperature detector
Inventor: MUTOO KATSUTOSHI
IPC: G01J5/08
Filed: 1978-07-17
Abstract: PURPOSE:To enable accurate temperature measurement to be achieved without being influenced by electrical noise, by taking out temperature variation as variation of ligh intensity by utilizing variation of retardation relative to temperature variation of optical crystal equipped with optical anistropy. CONSTITUTION:A light having passed a temperature sensor 5 consisting of optical crystal, due to retardation of temperature of an object of temperature detection, changes to rectilinear polarization, circular polarization, oval polarization and then back to rectilinear polarization with increses of phase difference between normal light and abnormal light if, for instance, the optical crystal is one-axis crystal. And therefore, taken out from an analyzer 6 is a rectilinear polarization whose amplitude is varied according to condition of polarization, that is, light intensity corresponding to variation of temperature of the object of the temperature detection. Thus radiated light is taken into a light detector 9 and convereted into an electrical value corresponding to amplitude of rectilinear polarziation. As temperature variation of the object of temperature detection is taken out as variation of temperature intensity in this manner, temperature measurement (or reading) can be achieved accurately without being influenced by electrical noise.

Abstract: PURPOSE:To simply detect the failure temperature rise of a gas insulated apparatus, by holding a sensing substance discharging a gaseous product of neutral at a prescribed temperature to a holder provided near or in contact with the power conducting part in an insulating gas. CONSTITUTION:When a current flows to a conductor 32 via a slider 4 from a conductor 31, if the contact resistance of a contact part 42 is increased due to various causes and abnormal temperature rise is caused due to the increase in heat, the temperature in a tank 6 rises. When the temperature reaches a prescribed temperature a metallic carboxylate 62 in the tank 6 is thermally decomposed and gaseous carbon dioxide is discharged, and this discharged gas is mixed uniformly in an insulating gas through convection and diffusion. The gaseous carbon dioxide once decomposed is left as a carrier without being adsorbed to an adsorbing member which adsorbs decomposed products due to arc of gaseous SF6 and water content, then the presence or absence of a failure can be known quantitatively by analyzing a few amount of gas from an intake 8 at the occasion of periodic inspection.
