Disclosed is a two-dimensional X-ray detector array inspection method capable of recognizing two-dimensional X-ray detector arrays unsuitable for X-ray imaging by means of identifying quickly growing defective pixels. The two-dimensional X-ray detector array inspection method involves a bias voltage step for repeated supply and stopping of a bias voltage from a common electrode; a dark current value measurement step for measuring the pixel values of pixels in a non-X-ray-irradiating state; a defective pixel identification step for identifying defective pixels on the basis of the pixel values of the pixels measured in the dark current value measurement step; and a determination step for determining whether or not the two-dimensional X-ray array detector is suitable on the basis of the size of the missing pixel chunks or the total number of defective pixels identified in defective pixel identification step.

A radiation detector of this invention has an insulating, non-amine barrier layer disposed between exposed surfaces of a radiation sensitive semiconductor layer, a carrier selective high resistance film and a common electrode, and a curable synthetic resin film.This barrier layer can further inhibit a chemical reaction between the semiconductor layer and curable synthetic resin film, and can prevent an increase in dark current which flows through the semiconductor layer. Since no chemical reaction occurs between the barrier layer and semiconductor layer, the semiconductor layer will never be degraded. Further, with an auxiliary plate disposed on an upper surface of the curable synthetic resin film, it is possible to manufacture a radiation detector free from warpage and cracking due to temperature change.

A plasma display panel has a front substrate, a rear substrate, and a phosphor layer. The front substrate has a dielectric layer formed so as to cover a plurality of display electrodes disposed on a substrate, and a protective layer formed on the dielectric layer. The rear substrate is faced to the front substrate so as to form discharge space, has data electrodes in the direction intersecting with the display electrodes, and has barrier ribs for partitioning the discharge space. The phosphor layer is formed by applying phosphor ink that is made of a phosphor material and dispersant between the barrier ribs of the rear substrate. Nano-particles with a diameter of a range of 1 nm to 100 nm inclusive, or a solvent having an affinity for the dispersant of the phosphor ink is applied to the surfaces of the barrier ribs, and then the phosphor ink is applied to them, thereby forming the phosphor layer.

摘要:
A magnetic recording medium having a high magnetic pattern contrast is manufactured. By changing an acceleration voltage that accelerates ions in a process gas, depths (peak depths D0 and D1) from a magnetic layer 44, at which an injection amount of a target element is the maximum, can be made with set depths even if a film thickness of an ion permeation portion 48, which is a thin film portion of a resist 49, decreases. Since the set depths are achieved for the peak depths D0 and D1, a portion to be processed 43 of the magnetic film 44 is made non-magnetized from a top surface to a bottom surface, and a magnetic portion is separated; thus, the magnetic recording medium with a high magnetic pattern contrast can be obtained.
