Title: Method for evaluating life of bolt
Inventor: TAKEI MASAO
IPC: G01M13/00
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To evaluate a life with high reliability by forming a test piece by retaining several threads of a bolt under test and boring a center portion, and executing a general purpose creep or low cycle fatigue test via a jig to be engaged with the threads. SOLUTION: Several threads of a base end of a bolt under test are retained at an engaging part of a bolt under test with female threads, and cut by retaining a base end side. Thereafter, the treads are bored in an axial hole of a predetermined diameter to form coaxial threaded hole to a test piece 7. The base end side of the piece 7 is engaged with a drug rod 9a of a tester, and a thread side is engaged with a jig 8 having female threads engaged with a drug bar 9b. It is applied to a general purpose creep or low cycle fatigue tester. Thus, the piece 7 is formed, several threads are loaded, and testing load is shared at several threads to a load shared at the several threads in a practical use state.  Thus, a stress distribution from the threads to roots of the thread becomes similar to a real bolt to obtain a testing condition near using stress condition of the real bolt, and hence its life evaluation has high reliability.

Title: Testing method for resisting property of refractory against thermal shock
Inventor: KUMAGAI MASATO
IPC: G01N3/60
Filed: 1981-11-05
Abstract: PURPOSE:To measure the resisting property against thermal shock suppressing the mixing-in of the noise due to abnormal high temperature by directing laser light in pulses and detecting acoustic emission signals only during the laser output is stopped. CONSTITUTION:A gate circuit 7 is provided between a laser light output controller 3 and an acoustic emission (AE) measurement device 6. The gate 7 stops measurement of AE signal while a laser light is being applied, and it makes measurement only when the output of the laser light is stopped. The laser light is applied in pulses to actuate the gate circuit 7, and when the AE signal is detected while the output is stopped, the mixing-in of noises accompanying cracks as in the figure can be stopped and only AE signal due to cracks is detected. In the curves, it is known that the material B is continuous without stepped material changes and it has a resistance to the advance of crack better than that of the material A. In this way the resisting property against thermal shock can be measured with high accuracy.

IPC: G11B5/85
Filed: 1986-07-28
Abstract: PURPOSE:To obtain a recording medium provided with good S/N and durability in short wavelength recording with a large area by forming a 1st magnetic layer on a high-polymer film, then transferring the coating agent on the rear face of the high-polymer film thereto to impart the shape to said layer in the wound state and forming a 2nd magnetic layer thereon. CONSTITUTION:A PE terephthalate film is mounted to a shaft 2 and while the film is moved in a rotating direction A along a cooling can 4, the 1st magnetic layer is formed on the film by electron beam vapor deposition of CoNi. The film is then taken up on a shaft 3 by a system for decreasing tension gradually. While a shutter 7 is held closed, the film is rewound (rotating direction B) on a 1st shaft 2 and the 2nd magnetic layer is formed by the electron beam vapor deposition of the CoNi on the 1st magnetic layer while the web is again moved in the rotating direction A. The Co salt of a stearic acid is thus deposited by evaporation. The magnetic characteristics are thereby macroscopically uniformized and the noise of the resultant medium is improved.
