The sputtering inclination assembly may further increase a uniformity of the thin film thickness. | 01-28-2016 |
20160033658 | SEMICONDUCTOR RADIATION DETECTOR ARRAY - A radiation detector with improved performance includes a probe and a first detector element constructed from planar semiconductor material in the probe. The detector further includes a second detector element constructed from planar semiconductor material in the probe. The detector further includes a focal point located outside of the probe. The detector further includes a circuit in communication with the detector elements.

The circuit receives the signals generated by the detector elements. | 02-04-2016 |
20160056313 | COMPOUND SEMICONDUCTOR SINGLE CRYSTAL INGOT FOR PHOTOELECTRIC CONVERSION DEVICES, PHOTOELECTRIC CONVERSION DEVICE, AND PRODUCTION METHOD FOR COMPOUND SEMICONDUCTOR SINGLE CRYSTAL INGOT FOR PHOTOELECTRIC CONVERSION DEVICES - The present invention increases the conversion efficiency of a photoelectric conversion element that uses cadmium zinc telluride or cadmium telluride (Cd(Zn)Te) compound semiconductor single crystals containing a group 1A element as an impurity. A heat-resistant pot is filled with raw material and a group 1A element, which is reacted with a portion of the raw material, and the container is heated, thereby melting the raw material into a melt and diffusing the dissociated group 1A element in the melt, producing single crystals from the melt.

20160091412 | SYSTEMS FOR DETERMINING AND IMAGING WAX DEPOSITION AND SIMULTANEOUS CORROSION AND WAX DEPOSIT DETERMINATION IN PIPELINES - The systems for determining and imaging wax deposition and simultaneous corrosion and wax deposit determination in pipelines relate to systems for determining wax deposition and corrosion by one or both of two techniques. In both techniques, a source of neutron radiation is directed at the pipeline. In one technique, a neutron detector surrounded by an absorption shield defining a collimation window counts neutrons reflected back to the detector by back diffusion or backscatter radiation. In the other technique, a gamma ray detector measures gamma rays emitted when the emitted neutrons are absorbed in the pipeline. A neutron moderator-reflector is placed around three sides of the pipeline to increase the likelihood of neutron capture. | 03-31-2016 |
20160103233 | ORGANIC-INORGANIC COMPOSITE FILMS AND METHODS OF MANUFACTURING THE SAME - A method of manufacturing an organic-inorganic composite thin film may include: forming a thin film from a paste that includes an inorganic powder and an organic compound binder by using a screen printing process; and/or performing a pressing process and a heating process with respect to the thin film. The heating process may be performed at a glass transition temperature of the organic compound binder or in a temperature range higher than the glass transition temperature of the organic compound binder. An X-ray detector configured to detect X-rays irradiated from an outside of the X-ray detector may include: a photoconductive material layer in which electron-hole pairs are formed due to absorption of the X-rays. The photoconductive material layer may be formed of an organic-inorganic composite thin film that includes an inorganic powder and an organic compound binder. | 04-14-2016 |
20160148962 | THREE LEVEL TRANSFER GATE - A method and device of driving a radiation sensor pixel is disclosed. The sensor pixel comprises a sensing element capable of charge generation as a response to impinging radiation, a floating diffusion node, a transfer gate between the sensing element and the floating diffusion node, and a charge storage device connected to the floating diffusion node via a switch. The method comprises biasing the transfer gate to three or more bias voltages OFF, ON and an intermediate bias between OFF and ON. During the period in which the transfer gate is biased to the intermediate bias, if the sensor reaches saturation, the overflown charges may be collected and part of them stored in the charge storage device, for further analysis and merging. | 05-26-2016 |
20160163492 | DETECTOR AND METHOD FOR DETECTING ULTRAVIOLET RADIATION - An electron filtering layer placed on a photocathode of a UV light detector allows to selectively filter out electrons generated from a photoconversion of long wavelengths. The filter may be tuned by selecting the material and the thickness of the electron filtering layer. By means of the filtering layer, background noise due to visible parts of the spectrum may be efficiently suppressed. Applications of the invention include a solar-blind flame and/or smoke detector. | 06-09-2016 |
