20140233689 | Water Jet Peening Apparatus and Water Jet Peening Method - In a water jet peening apparatus, a high-pressure under-water pump is installed on an upper end of a casing and an injection nozzle drive mechanism equipped with an injection nozzle is attached to the casing. A high-pressure hose whose one end is connected to the high-pressure under-water pump is disposed in the casing and the other end of the high-pressure hose is connected to the injection nozzle. The casing is seated at an upper end of a control rod drive mechanism housing and the high-pressure under-water pump is driven. The high-pressure water pressurized by the high-pressure under-water pump is supplied to the injection nozzle through the high-pressure hose in the casing and is jetted toward the weld portion between the control rod drive mechanism housing and a stub tube. The time required for a water jet peening operation can be shortened. | 08-21-2014 |

20090056399 | METHOD FOR EXECUTING WATER JET PEENING - A method for executing water jet peening for giving an impact force to a surface of a structure member by a crushing pressure of a water jet and cavitation and improving residual stress, or washing, or reforming said surface, | 03-05-2009 |
20110232348 | EVALUATION METHOD OF RESIDUAL STRESS IN WATER JET PEENING AND METHOD OF EXECUTING WATER JET PEENING - An evaluation method of residual stress in water jet peening includes a step of creating an analytical model including meshes according to a water jet peening (WJP) object, the shape of a nozzle, and an injection distance, a step of inputting WJP execution conditions, a step of calculating the internal pressure p | 09-29-2011 |
20130044864 | X-Ray Diffraction Instrument - There is provided an X-ray diffraction instrument including: a two-dimensional plate-like X-ray detector; an X-ray emitter integrated with the X-ray detector so as to penetrate the plate of the X-ray detector; a cylinder-like shield to define an orientation of the X-ray emitter and to prevent X-ray leakage, the X-ray detector being attached to one open end of the cylinder-like shield; and a standard powder attachment device to attach a standard powder for X-ray diffraction measurement to a surface of an object to be measured. The X-ray diffraction instrument can perform an X-ray diffraction measurement to an object larger than the X-ray detector thereof. The invented X-ray diffraction instrument is small in size, and can perform accurate X-ray diffraction measurement of stationary immovable objects without limitation on an orientation of the measurement surface. In addition, X-ray leakage is prevented for operator safety. | 02-21-2013 |
