Abstract: Disclosed are a backscattered ray shielding mechanism and a portable X-ray generating device comprising the same. The backscattered ray shielding mechanism according to the present invention is mounted on a portable X-ray generating hand-held device to emit X-rays and blocking backscattered X-rays during X-ray emission and includes a lead-free lightweight shielding member, which is detachably or foldably mounted as a convertible form on an X-ray emitting unit of the portable X-ray generating device and partially supported by the X-ray emitting unit.

Abstract: Disclosed is a direct-conversion-type X-ray detector, including a first electrode on a substrate, a semiconductor structure including a photoconductor using a perovskite material on the first electrode, and a second electrode on the semiconductor structure.

Abstract: The present invention relates to radiation-shielding clothing for limiting the radiation exposure of radiographers and assistants at the time of radiography by using a lightweight lead-free sheet shielding X-rays, the radiation-shielding clothing including: a top main body including a torso portion; and a shielding sheet, at least a part thereof being capable of being coupled to or detached from the top main body using attachment and detachment means, wherein the shielding sheet contains a substrate of a resin material and tungsten or tungsten oxide powder.

Abstract: The present invention relates to an automatic oral sensor sterilizing and packaging system and, particularly, to an automatic oral sensor sterilizing and packaging system capable of automatically sterilizing an oral sensor and further packaging the oral sensor with disposable wrapping paper, comprising: a housing including a sterilization unit providing a sterilization region for sterilization of the oral sensor and/or a packaging unit providing a packaging region for packaging the oral sensor; and a transfer unit for making the oral sensor pass through at least one of the sterilization region and the packaging region.

Abstract: The present invention relates to a flip cover plate (10) for a mobile terminal, the plate comprising: a cover plate inserted into a flip cover which opens and closes the front portion of the mobile terminal; and a transparent window coupled to one side of the cover plate and exposing a portion of a liquid crystal of the mobile terminal to the outside when the flip cover is positioned at the front portion of the mobile terminal, wherein the transparent window is configured to be bonded to at least one surface of the cover plate corresponding to in opening of the flip cover. Accordingly, the present invention has an advantage of maximizing productivity compared to production through one by one cutting processes by means of a conventional numerically controlled machine tool.

Abstract: The present invention relates to a mobile phone protection case film with a transparent part and a method for manufacturing the same, and specifically a method for manufacturing a protection case film inserted in a protection case cover hinged to one side of a protection case for receiving the back and the sides of a mobile phone so as to open or close the front of the mobile phone, includes the steps of: assembling a first die and a second die so as to form a cavity conforming with the shape of the protection case film; filling the cavity with a molten resin through a gate provided in one side of the cavity; compressing the molten resin filling the cavity by closely contacting the first die and the second die with each other; cooling or hardening the molten resin; removing the molded product by separating the first die and the second die; and cutting off the gate from the molded product.

Abstract: Disclosed herein is a method of detecting fine surface defects, including: applying nano phosphor paste on a surface of a subject; squeegeeing the surface of the subject such that the nano phosphor paste remains only in defects in the subject; and detecting the fine defects in the subject by placing the subject over a light detection plate, irradiating the subject with a light source, and then determining that light-emitting portions detected using the light detection plate are defects in the subject. The method of detecting fine surface defects is advantageous in that the problems with the conventional methods, such as surface contamination, the difficulty in realizing uniform application of a penetrant on a subject, the limitations on the dwelling time of the penetrant and the testing temperature (surface temperature of the subject: 16˜50° C.
