Filed: 1985-04-04
Abstract: PURPOSE:To inspect properly the peel state by giving a magnetic field to a conductive subject to be heated under a non-conductive material through a guide heating means and detecting the heat diffusion state at this time by an infrared ray camera. CONSTITUTION:The overall tester is placed on a self-traveling carriage, and an induction coil 5 is shifted in the state where it is separated from the surface of the non-conductive material by the prescribed distance.

Abstract: PURPOSE:To provide a rail excellent in the safety and preventing the derailment of a train by terminating a brittle cracking developed in the web part of rail or immediately developing the cracking to the bottom part side of rail. CONSTITUTION:In the longitudinal direction of the surface on the head part of rail after applying a roller straightening, a compressive residual stress is retained and in the longitudinal direction of the surface on the bottom part of rail, the equal compressive residual stress to the surface on the head part of rail is retained, or in the longitudinal direction of the surface on the head part, the compressive residual stress is retained and in the longitudinal direction of the surface on the bottom part of rail, a tensile residual stress is retained.

Title: System for detecting bubble in fluid flowline
Inventor: SUGINO TAKASHI
IPC: G01N15/12
Filed: 1982-04-28
Abstract: PURPOSE:To make it possible to prevent obstacles accompanied by the mixing of air bubbbles, by detecting air bubbles mixed in a fluid flowline such as a pipe connecting an ink nozzle row and an ink tank by the variation in the electric resistance value of a fluid at the point of time when air bubbles are mixed in said flowline. CONSTITUTION:An electrode 28 is arranged in a multi-nozzle head 21 in the vicinity of one end part of an ink flowline while an electrode 29 is arranged to the bottom part of an ink tank in the vicinity of the other end part of said flowline and D.C. voltage is applied to said electrodes from a power source 31 through a resistor 30 between the electrodes while the resistor 30 is amplified by a differential amplifier 32 to be taken out from an output terminal 33. Because this detected output voltage is lowered when an ink in a pipe 23 is interrupted by the mixing of air bubbles 26 and electric resistance between both electrodes is increased while a current is reduced, air bubbles 26 can be detected. When a pump 27 is operated corresponding to the variation in the detected output voltage to suck out the ink having air bubbles mixed therein, the detected output voltage value is restored to a usual state and, therefore, obstacles such as the interruption of the ink are prevented.

IPC: H01M4/50
Filed: 1980-05-27
Abstract: PURPOSE:To flatten the discharge characteristic of a battery, which contains both lithium used as a negative active material and manganese dioxide used as a positive active material, by treating the positive mixture subjected to heat treatment under a reduced pressure while heating it, before the positive mixture is used for assembling the battery. CONSTITUTION:An organic electrolyte battery includes a lithium 3 used as a negative active material, and a positive mixture 5 which is prepared by treating manganese dioxide and is used as a positive active material. The positive mixture 5, before it is used for assembling the battery, is subjected to heat treatment at 250- 450 deg.C, and is treated under a reduced pressure for 4 to 50 hours while being heated at below 200 deg.C. As a result, since the reaction products developed by the reaction between graphite and manganese dioxide during the heat treatment of the positive mixture 5 can be eliminated, the battery can provide a flat discharge characteristic of below 3.2V from the initial stage of the discharge. Besides, the increase in the internal resistance of the battery caused during the preservation can be reduced to a large extent.

The position of the point A is detected as X-Y rectangular coordinate values having an origin at the upper left corner of the screen 4a. The point B is detected in the same manner and the measuring means measures the length between the points A and B.
