A thin film magnetic head includes a magnetic core composed of upper and lower magnetic pole films spaced apart to define a read-write gap and a coil disposed between the upper and lower magnetic pole films in an area outside of the gap. The upper and lower magnetic pole films each comprise a thin-film laminate having alternating magnetic and non-magnetic thin films. The magnetic thin film includes an amorphous Co alloy having a soft magnetic property and a thickness within a range of 0.1 .mu.m to 0.5 .mu.m and the non-magnetic thin-film includes a non-magnetic metal or an insulating nitride.

摘要:
A radiation image storage panel having a fluorescent layer which comprises a binder and a stimulable phosphor dispersed therein. Further, the panel is colored with a colorant so that the mean reflectance of the panel in the wavelength region of the stimulating rays of the stimulable phosphor is lower than the mean reflectance of the panel in the wavelength region of the light emitted by the stimulable phosphor upon stimulation thereof. The panel provides an image of high sharpness.

摘要:
A radiation image storage panel having a stimulable phosphor layer and an improved protective film is disclosed. The improved protective film is produced from a mixture of a film-forming resin and an oligomer having a polysiloxane skeleton or a perfluoroalkyl group. The improved protective film can be a coated layer containing a fluorocarbon resin which is soluble in an organic solvent. Otherwise, the improved protective film can be produced by coating on the phosphor layer a mixture of a film-forming resin composition containing a fluorocarbon resin which is soluble in an organic solvent, and a powdery resin of perfluoroolefin or silicone.
