  • Patent number: 5036207
    Abstract: Disclosed is a radiation image storage panel having a stimulable phosphor layer including a stimulable phosphor which absorbs both a radiation in a wavelength shorter than 250 nm and ultraviolet rays in a wavelength of 250-400 nm, then which stores their energies, and which emits the energies as luminescence when it is exposed to irradiation of a visible light or an infrared ray; and also including a phosphor which spontaneously emits ultraviolet rays in a wavelength of 250-400 nm when it is excited by a radiation in a wavelength shorter than 250 nm. Also there disclosed is another radiation image storage panel having separately a stimulable phosphor layer and an ultraviolet ray emitting phosphor layer including the phosphor which emits ultraviolet rays in a wavelength of 250-400 nm when it is excited by a radiation in a wavelength shorter than 250 nm.

  • Patent number: 4949218
    Abstract: A cabinet for housing electronic equipment includes an integrally formed cooling system which includes an air conduct running longitudianlly between the opposite end walls of the cabinet in an upper portion thereof. A cooling fin assembly is fitted into a lower wall of the air duct so as to have its fins extend upwardly into the air duct and downwardly into the cabinet. Heat transfer takes place as heat from within the cabinet passes to the cooling fins which are then cooled by a pair of fans disposed at opposite ends of the air duct.

  • Patent number: 4936342
    Abstract: A fuel pressure control valve device comprising: a case; a fuel introducing port and a fuel discharge port; a diaphragm dividing the interior of the case into two chambers; an armature; a resilient member; a pole constituting a fuel passage for discharging fuel; and a sphere as a valve body for opening or closing the fuel passage in the pole. The fuel passage in the pole includes: a fuel passage for guiding the sphere; a valve seat to be abutted against the sphere; and a resilient member for giving a biasing force to the sphere to abut the sphere against the armature. Auxiliary fuel passages are formed in or on the wall of the fuel passage for guiding the sphere. A spring seat is provided at the outer peripheral portion thereof with a stepped portion which receives a coil spring.

  • Patent number: 4788434
    Abstract: A radiation image recording and reproducing method comprising steps of:causing a stimulable phosphor to absorb a radiation having passed through an object or having radiated from an object,exciting said stimulable phosphor with an electromagnetic wave having a wavelength within the range of 450-900 nm to release the radiation energy stored therein as light emission, anddetecting the emitted light,in which said stimulable phosphor is a divalent europium activated barium fluorohalide phosphor having the formula (I):BaF(Br.sub.1-x I.sub.x):yEu.sup.2+ (I)in which x and y are numbers satisfying the conditions of 1.times.10.sup.-3 .ltoreq.x<1.0 and 0<y.ltoreq.0.2, respectively.
