Plasma display panel provided with a discharge electric increasing member and/or a discharge electric field controller

A plasma display panel of a matrix display type, having a first electrode and a second electrode which constitute a main electrode pair, the first electrode and the second electrode being covered with an insulating layer against a discharge gas, wherein the insulating layer comprises a magnesium oxide film formed at least as a surface layer thereof which is in contact with the discharge gas, the magnesium oxide film having an impedance in the range of 230 to 330 k&OHgr;/cm,at a frequency of 100 Hz.

Plasma display panel with insulating layer having specific characteristics

A process for forming a fluorescent layer on an electrode disposed on a substrate for display panel includes the steps of: placing an opening of a housing section for housing a fluorescent paste opposite to the electrode on the substrate; and applying a voltage between the electrode on the substrate and a control electrode disposed inside the housing section in this state, whereby the fluorescent paste inside the housing section is exactly applied onto the electrode via the opening. Also, an apparatus for forming a fluorescent layer on a substrate for display panel using the process is disclosed.

Process and apparatus for forming fluorescent layer on a substrate for

A fluorescent layer formation process which comprises dispersing particles of a fluorescent substance and particles of a (meth)acrylic resin as a binder or particles of the fluorescent substance coated with the (meth)acrylic resin in a medium incapable of dissolving the resin therein to prepare a fluorescent paste; applying the fluorescent paste on a fluorescent layer formation surface to form a paste layer; and baking the paste layer at such a temperature that the resin is substantially decomposed or burnt out, thereby to form a fluorescent layer.

A novel stimulable phosphor having a high sensitivity to a semiconductor laser as a stimulating light is disclosed, and is represented by the formula:

Stimulable Phosphor

A method for forming an X-ray image. The method involves the use of an X-ray transforming sheet which includes a novel stimulable phosphor on a substrate. The phosphor has a high sensitivity to a semiconductor laser as a stimulating light and is represented by the formula:

Method of forming an x-ray image using photostimulable phosphor

A digital X-ray apparatus forms a latent image of an object on a photostimulable phosphor plate as an energy distribution pattern using X-ray energy and reads the latent image using an excitation light beam. A plate, of a material which does not transmit the excitation light beam, has holes formed therein with photostimulable phosphor positioned in the holes, the photostimulable phosphor emitting a fluorescent light when irradiated by the excitation light beam, the emitted light beam gathered and a corresponding signal produced. The excitation light beam reflected from the photostimulable phosphor plate is also gathered and a signal responsive thereto also is produced. A method of production by stacking and bonding plural metal sheets having appropriate patterns of holes therein with the photostimulable phosphor and a transparent protection film layer thereon provides the structure of the photostimulable phosphor plate.

Photostimulable phosphor plate and photostimulable phosphor reader

In a digital X-ray apparatus for exposing an X-ray transmitted through an object onto a photostimulable phosphor plate, for scanning the photostimulable phosphor plate by an excitation beam, and for obtaining an X-ray image, the digital X-ray apparatus includes a switch unit connected to a storage unit and switching between a standard photographing mode and an actual photographing mode; a correction coefficient conversion unit converting the X-ray image data to an image data having a standardized lightness; a first storage unit storing an initial correction coefficient after standardization in the correction coefficient conversion unit; a second storage unit storing a correction coefficient after standardization in the correction coefficient conversion unit; a detection unit comparing a value of the correction coefficient from the second storage unit with a value of the initial correction coefficient from the first storage unit, and detecting whether or not a difference between the value of the correction coefficient at each picture element and the value of the initial correction coefficient at each picture element exceeds a predetermined threshold value; and a generation unit displaying a number of abnormal picture elements detected by the detection unit and generating an alarm message when the number of abnormal picture elements exceeds a predetermined number, the predetermined number being defined by a ratio of the number of abnormal picture elements to the number of all the picture elements.
