Abstract: A radiation image storage panel comprising a support and a phosphor layer provided thereon which comprises a binder and a stimulable phosphor dispersed therein, characterized in that said binder contains a (meth)acrylic copolymer in the amount of 5-100% by weight, which has repeating units represented by the formulas (I), (II) and (III): ##STR1## in which each of R.sub.1, R.sub.3 and R.sub.5 is independently a hydrogen atom or an alkyl group; R.sub.2 is a group selected from those consisting of an alkyl group, a cycloalkyl group, an aryl group, a heterocyclic group and an aralkyl group; R.sub.4 is a hydrogen atom or an alkyl group and R.sub.2 .noteq.R.sub.4 ; and x, y and z representing molar percents are numbers satisfying the conditions of 5.ltoreq.x.ltoreq.99, 1.ltoreq.y+z.ltoreq.95 and x+y+z.gtoreq.90. The (meth)acrylic copolymer is preferably employed in combination with a linear polyester having a hydroxyl value in the range of 20-70%.

Abstract: A radiation image storage panel comprising a support and a phosphor layer provided thereon which comprises a binder and a stimulable phosphor dispersed therein, characterized in that a friction-reducing layer having a surface of a friction coefficient of not more than 0.6 is provided on the support-side surface and/or the phosphor layer-side surface thereof.

Abstract: A radiation image storage panel comprising a support and phosphor layers provided thereon which comprise a binder and a stimulable phosphor dispersed therein, characterized in that said phosphor layers comprise the first phosphor layer on the support side and the second phosphor layer provided on the first phosphor layer, and that the mean particle size of the stimulable phosphor contained in said first phosphor layer is smaller than the mean particle size of the stimulable phosphor contained in said second phosphor layer.

Abstract: A radiation image storage panel comprising a support, a subbing layer and a phosphor layer which comprises a binder and a stimulable phosphor dispersed therein, superposed in this order, characterized in that said subbing layer contains fine particles having a size of 1-30 .mu.m in an amount of 1-200% by weight of a resin constituting the subbing layer.

Abstract: A radiation image storage panel comprising a support, a subbing layer and a phosphor layer which comprises a binder and a stimulable phosphor dispersed therein, superposed in this order, characterized in that said subbing layer comprises a synthetic resin crosslinked with a crosslinking agent.

Abstract: A radiation image storage panel comprising a substrate, a fluorescent layer provided on the substrate and composed of a binder and a stimulable phosphor dispersed therein, and a protective layer provided on the fluorescent layer. The panel is edge-reinforced by coating the edge faces thereof with a polymer material comprising polyurethane or acrylic resin.

Abstract: 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.

Abstract: A movement controlling device for the movement of a movable member such as a table in a machine tool which is capable of doing a rapid feeding, a normal feeding for cutting, and a rapid returning. The movable member is driven by a fluid pressure cylinder and engaged, at a predetermined position in the forward movement stroke, with a rack which is linked to a motor by way of the gearing mechanism including a worm and a worm-wheel. The motor is so driven, due to a signal from a sensor for sensing the engagement between the rack and the movable member, as to shift the rack at the speed of cutting feed in the same direction as that of the forward movement of the movable member, and the movable member which is driven by the fluid pressure cylinder is also shifted in response to the shift of the rack.
