20120133520 | COMPUTER CHASSIS SYSTEM AND HARD DISK STATUS DISPLAY METHOD THEREOF - A computer system displays and controls the hard disk condition. The computer system includes a host bus adapter which detects the status of the hard disk, and the status light gives light to display the hard disk status. The baseboard management controller and the host bus adapters are set on the motherboards, in which the baseboard management controller monitors and records the status of the hard disk. The microcontroller is set on the hard disk backplane for decoding the message from the host bus adapter in order to control the displaying of the status light. | 05-31-2012 |

20120196518 | Grinding mechanism - A grinding mechanism includes a rotating body, a first grinding wheel, a second grinding wheel, a first fastening means, a second fastening means, and a spacer assembly, a first fastening means passing through the first body portion and fastening into the rotating body, a second grinding wheel including a second body portion and a second grinding portion. The first and the second grinding portions have different diameter from each other, and are spaced from each other axially, and have different grinding precisions. The spacer assembly is interposed between the first grinding wheel and the second grinding wheel. The second fastening means passes through the second body portion and the spacer assembly, and threadedly fastens into the first body portion, so as to press and secure the second body portion and the spacer assembly against and on the first body portion. | 08-02-2012 |
20120214388 | Position adjustment mechanism of grinding wheels - A position adjustment mechanism for grinding wheels includes a rotating body, a first grinding unit, a second grinding unit, and a fixing nut. The rotating body includes a fixing surface and a first thread portion. The first grinding unit includes a first grinding portion and a fixing portion fixedly engaged with the fixing surface. The second grinding unit includes a second thread portion, which is threadedly engaged with the first thread portion of the rotating body, and a second grinding portion which is spaced from the first grinding portion and which has a different grinding precision from that of the first grinding portion. The fixing nut is threadedly engaged with the first thread portion, and presses axially against the second grinding unit. Thereby, a rough grinding and a fine grinding can be accomplished together within a grinding process, and adjustment on a spacing between the two grinding wheels becomes easy. | 08-23-2012 |

20160138184 | MELT SURFACE FLOW FIELD MEASUREMENT METHOD FOR ARTIFICIAL CRYSTAL GROWTH SYSTEMS AND CRYSTAL GROWTH APPARATUS UTILIZING THE METHOD - A melt surface flow field measurement method that captures flow rates at multiple tracking points and their mapping on melt surface for artificial crystal growth systems includes the following steps: (A) capture two consecutive images of the melt surface at a time interval of Δt; (B) define the significant regions in the first image as a plurality of first grid regions, then calculate centroid coordinates of the first grid regions; (C) define the regions in the second image corresponding to the significant regions in the first image as a plurality of second grid regions, then calculate centroid coordinates of the second grid regions; (D) lay the second set of centroid coordinates over the first grid regions, and calculate the distances between corresponding centroid coordinates to determine the displacement of the identified significant regions; and (E) divide the displacements by the time interval Δt to determine the flow rate and direction of each identified significant region on melt surface at their centroids—the tracking points. | 05-19-2016 |
