摘要： PROBLEM TO BE SOLVED: To provide a system, a method, and an apparatus for back-projection reconstruction of filter processing of digital tomosynthesis. SOLUTION: A system, a method, and an apparatus to reconstruct a fine and clear 3D image (118) from a series of 2D images by a special back-projection processing are provided by pre-filtering a two-dimensional (2D) image using a first group setting and then post-filtering a three-dimensional (3D) image using a setting of another group before back-projecting the 2D image so as to form the 3D image(118). In some embodiments, setting of a first group and setting of a second group are mutually synergistically optimized for providing enhancement to a region of interest structure in a subject.

摘要： PROBLEM TO BE SOLVED: To provide a three-phase non-dissociating disconnector switch which is durable to a large current conduction. SOLUTION: Each finger includes an inside front surface having a first upheaval surface part and a second upheaval surface part. The first upheaval surface part has a first flat surface zone part 106. This flat surface zone part is brought into contact with the head part 72 of the second end part of a switch blade or the finger end 60 which can be removed actually. The second upheaval surface part of the finger has a second flat front surface zone part 108 engaged with the second blade-like connector part 28 of the second terminal. The upheaval surface part and each flat front surface zone part 108 increase the front surface contact area between the finger and the blade member 50 and between the finger and the second blade-like connector part 28 of the second electric terminal. This improves the capability to raise the rated current of the switch and to bear a short circuit. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for repairing an aluminum compound-diffused coating on parts (10). SOLUTION: This repairing method includes treating the coating (20) by an aqueous solution of nitric acid and phosphoric acid until at least a portion of an additive layer (22) of the coating (20) is removed but a diffusion area (24) existing under the additive layer (22) remains. Next, the exposed surface of the parts (10) is deposited and formed with additional aluminum by realuminization and is formed with the additive layer (22) up to a desired thickness. This method is particularly applicable to the aluminum compound-diffused coating (20) which is deposited on the parts (10) so as to have the excessively thick additive layer (22) and before the parts (10) are returned for practicable use.

摘要： PROBLEM TO BE SOLVED: To provide a seal between the upper and lower halves of an inner compressor discharge case. SOLUTION: The upper and lower halves 28, 30 of an inner barrel of a compressor for a turbine are bolted to each other in a state of metal-to-metal surface contact. An elongated groove 36 is provided at the edge part 34 of one of the barrel halves. An elongated composite tubular woven seal 36 is arranged in the groove, and the seal has a diameter exceeding the depth of the groove. The seal comprises an inner woven metal core 42 surrounded by an annular silica fiber layer 44 and then surrounded by a metallic foil 46 with an outer protective covering 48 of a braided stainless steel. Upon joining the upper and lower halves, the compliant seal is crushed within the groove, maintaining a seal between the barrel halves in the event of warpage of the compressor casing during turbine operation.

摘要： PROBLEM TO BE SOLVED: To provide improved impingement cooling constitution for the trailing edge region of a comparatively small turbine blade airfoil part. SOLUTION: A turbine airfoil part (12) includes positive and negative pressure side walls (20 and 22) having first and second flow passages (32 and 34) separated by a bridge (36) situated therebetween and extending in a longitudinal direction. The bridge includes a row of inlet holes (46) and a row of outlet holes (48) extends from the second flow passage toward the trailing edge (26) of the airfoil part. A row of turbulator ribs (50) is situated in the second flow passage along the positive pressure side wall, and the ribs are longitudinally elongated and situated on the same and one straight line. The ribs face the inlet hole and are crossover-impingement-cooled by air guided from the ribs. COPYRIGHT: (C)2003,JPO
