20090261254 | RADIATION IMAGE CONVERTING PANEL - The present invention relates to a radiation image converting panel with a structure capable of arbitrarily controlling the luminance distribution of the panel surface after formation of a protective film according to usage conditions. The radiation image converting panel comprises a support body and a radiation converting film formed on the support body. The radiation converting film is formed on a film forming region which existes within a first main surface of the support body and includes at least a gravity center position of the first main surface. The film thickness of the radiation converting film is adjusted such that the maximum difference can be obtained in either one of a peripheral area and a middle area from a central area including the gravity center position. | 10-22-2009 |
20090261272 | RADIATION IMAGE CONVERTING PANEL - The present invention relates to a radiation image converting panel that effectively prevents deterioration in fluorescence lifetime by a simpler structure. The radiation image converting panel comprises a support body, and a radiation converting film formed on the support body. The radiation converting film is formed on a film forming region which exists within a first main surface of the support body and includes at least a gravity center position of the first main surface. The radiation converting film is doped with Eu, and an Eu concentration distribution has a concentration gradient so as to become higher in the periphery than in the vicinity of the center of the radiation convert film. By thus providing a concentration gradient for the concentration of Eu to be doped, a drop in luminance in the periphery of the radiation converting film can be reduced. | 10-22-2009 |
20090261273 | RADIATION IMAGE CONVERTING PANEL - The present invention relates a radiation image converting panel with a structure capable of arbitrarily controlling a change in luminance distribution of an entire panel surface after formation of a moisture-resistant protective film. The radiation image converting panel comprises a radiation converting film doped with Eu and covered with a moisture-resistant protective film. The Eu concentration in the radiation converting film is preliminarily adjusted such that the Eu concentration at a central portion or peripheral portion of the film falls within an optimal range, and the other film portion is provided with a positive or negative concentration gradient such that the Eu concentration thereof gradually become higher or lower than the optimal range. The luminance distribution of the entire panel in which the moisture-resistant protective film has been formed can be controlled by providing the Eu concentration to be added with a concentration gradient. | 10-22-2009 |
20090261274 | RADIATION IMAGE CONVERTING PANEL - The present invention relates to a radiation image converting panel with a structure to realize an improvement in moisture resistance in the periphery of the panel. The radiation image converting panel comprises a support body and a radiation converting film formed on the support body. The radiation converting film is formed on a film forming region which exists within a first main surface of the support body and includes at least a gravity center position of the first main surface. An average crystal diameter of columnar crystals located on a peripheral measuring area of the film forming region is controlled to be 1.3 times or more larger than an average crystal diameter of columnar crystals located on a central measuring area corresponding to a gravity center position of the film forming region, whereby moisture resistance in the periphery of the panel is improved, so that a sufficient fluorescence lifetime of the panel as a whole is maintained. | 10-22-2009 |
20110031415 | RADIATION IMAGE CONVERTING PANEL - The present invention relates a radiation image converting panel with a structure capable of arbitrarily controlling a change in luminance distribution of an entire panel surface after formation of a moisture-resistant protective film. The radiation image converting panel comprises a radiation converting film doped with Eu and covered with a moisture-resistant protective film. The Eu concentration in the radiation converting film is preliminarily adjusted such that the Eu concentration at a central portion or peripheral portion of the film falls within an optimal range, and the other film portion is provided with a positive or negative concentration gradient such that the Eu concentration thereof gradually become higher or lower than the optimal range. The luminance distribution of the entire panel in which the moisture-resistant protective film has been formed can be controlled by providing the Eu concentration to be added with a concentration gradient. | 02-10-2011 |

20080223195 | Keyboard Assembly for Playing Music Automatically - A keyboard assembly for playing music automatically comprises: a plurality of juxtaposed keys including white keys and black keys, each being supported swingable for depression and release thereof; a plurality of juxtaposed swing weights, each for each of the keys and each being supported swingable as interlocked with the corresponding key; and a plurality of actuator devices, each for each of the swing weights to actuate the swing weight, which in turn drives the interlocked key to swing to its depressed position. The actuator devices are arrayed alternately in two rows with the arraying pitch between the actuator devices for the adjacent swing weights made different from the arraying pitch between the swing weights so that the actuator devices for the keys of C through E can be disposed closer to the C end and the actuator devices for the keys of F through B can be disposed closer to the B end, thereby securing a fitting space between the E actuator device and the F actuator device. Alternatively, the actuator devices may be equally spaced within the octave, while the swing weights are spaced unequally. | 09-18-2008 |
20080276789 | Electronic Keyboard Musical Instrument Having Key Actuators - An electronic keyboard musical instrument comprises a keyboard assembly including juxtaposed keys and juxtaposed swing weight mechanisms, each of the keys correspondingly linked with each of the swing weight mechanisms. The keyboard assembly is supported on a key bed having an aperture which is elongate in the direction of the key juxtaposition. Actuating members are provided corresponding to the respective swing weight mechanisms each of which in turn actuates each corresponding key. The actuating members are disposed in a lower yoke having a channel member and flanges integrally manufactured by bending a metal plate. The flanges are fastened to the key bed across and over the aperture so that the actuating members penetrate the aperture toward the swing weight mechanism. The height of the channel member determines a relative position between the actuating members and the swing weight mechanism. | 11-13-2008 |
20080289484 | Electronic Keyboard Instrument Having Key Driver - An electronic keyboard instrument comprises a storage device that stores automatic performance data including a first event for generating a musical tone and first timing data that defines a reproduction timing of the first event, a key-driving data generator that generates key-driving data including a second event corresponding to the first event included in the automatic performance data and second timing data that defines a reproduction timing of the second event and precedes the first timing data for a predetermined time, a keyboard that has a plurality of keys, a key driver that drives each of the plurality of keys in accordance with the key-driving data, a reproduction device that reproduces the automatic performance data and the key-driving data in parallel. The key-driving data generator generates the key-driving data before the reproduction device starts the reproduction. A reproduction process can be simplified even if keys are driven with the reproduction. | 11-27-2008 |
