Abstract: In a method of manufacturing a semiconductor device, a fin structure having a channel region protruding from an isolation insulating layer disposed over a semiconductor substrate is formed, a cleaning operation is performed, and an epitaxial semiconductor layer is formed over the channel region. The cleaning operation and the forming the epitaxial semiconductor layer are performed in a same chamber without breaking vacuum.

Abstract: Structural design of cranial nerve degeneration contrast agent precursor, the cranial nerve degeneration contrast agent prepared using the cranial nerve degeneration contrast agent precursor can be used for positron radiation tomography to detect alpha-synuclein.

Abstract: An ultrathin assembled speaker cone includes a support frame and a vibrating diaphragm. The support frame has a first support portion, a second support portion, and a connecting portion connected between the first support portion and the second support portion. Through the vibrating diaphragm, the problem that the conventional speaker cone is not sufficiently lightweight is effectively solved, and the material of the vibrating diaphragm may have more diverse options.

Abstract: A method for preparing a precursor used to label hepatocyte receptors is revealed. The precursor contains a bifunctional structure including trisaccharide and DTPA ligand. During synthesis processes of the precursor, silica gel columns and Reverse phase-18 (RP-18) columns are used for purification. Thus both the purification times and cost of each purification are reduced. Moreover, use diethyl ether to facilitate precipitation of products and remove a part of coupling reagent. Removing the coupling reagent helps purification of products. Furthermore, N?,N?-bis(carboxymethyl)-L-lysine hydrate and benzyl chloroformate are coupled to form a trisaccharide skeleton so as to ensure the yield rate of trisaccharide structure.

Abstract: A data distributing and accessing method for sharing a file via a network system includes steps of: dividing the file into a plurality of blocks; distributing the blocks in a plurality of data hosts interconnected via the network system; one of the data hosts receiving a file-reading request from a user host and issuing collecting requests to other data hosts to collect the blocks from the data hosts; and transferring the collected blocks from the data hosts to the user host to be combined into the file.

Abstract: A LED lamp having a locking device includes a lamp housing, a heat-sink, a locking device and a LED light-emitting module. The lamp housing has a cylinder. The heat-sink is formed with an annular wall. The locking device comprises a first thread formed at an outer periphery of the cylinder, a hook extending from one end of the cylinder, a second thread formed in the inner wall of the annular wall and threadedly connected with the first thread, and a groove defined on the annular wall and locked with the hook. The LED light-emitting module is placed in the heat-sink and connected to an end of the heat-sink away from the lamp housing. By the above arrangement, a secure and firm connection between the lamp housing and the heat-sink can be achieved.

Abstract: A straight down back light module including a diffuser plate, a lamp, a reflector plate (back plate) and a support. The reflector plate is located below the diffuser plate. The lamp is located between the diffuser plate and the reflector plate. The support is installed between the diffuser plate and the reflector plate. The support includes a lamp cover for supporting the lamp. The lamp is directly covered by the lamp cover for preventing the lamp from deformation that could occur because of temperature difference. When used in a large-sized liquid crystal display, at least one pin can be provided on the support in order to support the diffuser plate and the lamp so as to prevent them from deformation that could occur because of temperature difference.
