Systems and methods for improved simultaneous multi-slice (SMS) recording of scan data
In a method for improved recording of scan data of an examination object by means of a magnetic resonance system with the aid of a simultaneous multi-slice (SMS) method, a minimum repetition time TR is determined dependent upon a quality criterion. The quality criterion herein extends the scan time, which is actually greatly shortened by the use of an SMS method, for the MR signals of the slice stack to be recorded, to the minimum repetition time TR. The “time reserve” thereby obtained (the difference of the determined minimum repetition time TR from the scan time needed for the slice stack to be recorded purely by means of the SMS method) is utilized to take account of further slices in the recording of the MR signals. By this means, firstly, further information can be obtained and, secondly, the image quality of the image data obtained is improved. |

Delivery device usable in laser peening operation, and associated method
A delivery device that is usable in a laser peening operation emits a columnar flow of a fluid that contains therein a beam of electromagnetic energy. The beam is retained within the interior of the flow of fluid since the total internal reflectivity of the flow is sufficient to do so. The flow of fluid that serves as a conduit for the beam also itself impinges on a workpiece and thus contains and washes away the plasma that forms from a laser peening operation, and this resists the plasma from reaching and possibly damaging the delivery device. The carrying of the beam in the columnar flow of fluid avoids the need to maintain a fixed distance between the delivery device and the workpiece, which simplifies the movement by a robotic manipulator of the delivery device along a non-planar surface of a workpiece during a laser peening operation. |

Mold assembly
An assembly includes a first mold component defining a first portion of a mold cavity and a first slot. The first slot corresponds to a first portion of a retention channel. The assembly also includes a second mold component defining a second portion of the mold cavity and a second slot. The second slot corresponds to a second portion of the retention channel. The assembly also includes a connector having a cross-sectional shape corresponding to a cross-sectional shape of the retention channel. The connector has thermal expansion characteristics that are different from thermal expansion characteristics of the first and second mold components such that when the first and second mold components are in contact and the connector is inserted into the retention channel, heating the assembly causes differential thermal expansion of the connector and the mold components resulting in a clamping force between the mold components. |

Production method and coating device for coating-liquid-impregnated sheet-like reinforcing-fiber bundle and sheet-like integrated object
The present invention relates to a method of producing a coating liquid impregnated sheet-like reinforcing fiber bundle formed by applying a coating liquid to a sheet-like reinforcing fiber bundle that is unidirectionally arranged continuous reinforcing fibers long in one direction. The present invention provides a production method and a coating device of a coating liquid impregnated sheet-like reinforcing fiber bundle, wherein the method and device can effect continuous running without clogging of generated fuzz even at a high running speed and effect efficient impregnation of a coating liquid into the sheet-like reinforcing fiber bundle. The present invention relates to a method of producing a coating liquid impregnated sheet-like reinforcing fiber bundle, including allowing a sheet-like reinforcing fiber bundle, which is unidirectionally arranged reinforcing fibers, to pass substantially vertically downward through the inside of a coating section storing a coating liquid, whereby the method provides the sheet-like reinforcing fiber bundle with the coating liquid; wherein the coating section includes a liquid pool and a narrowed section which are in communication with each other; wherein the liquid pool has a portion whose cross-sectional area decreases continuously along a running direction of the sheet-like reinforcing fiber bundle, and wherein the narrowed section has a slit-like cross-section and has a smaller cross-sectional area than the top side of the liquid pool. |
