A method for processing an FM stereo signal. The FM stereo signal is digitized and divided into overlapping blocks, which are transformed into the frequency domain. Individual spectral lines of the difference signal are lowered if these have a higher magnitude than the respective spectral lines of the sum signal. The sum and difference signals are then transformed back.

In a disk drive suspension circuit, in order to improve stability of the stable pitch static attitude (PSA) over changes in humidity, the suspended portion of the flexible circuit and/or the gimbal support arm are modified to change their response(s) to humidity. In one embodiment, hygroscopic material such as the material of the insulating layer are added to the stainless steel gimbal support arm, so that in response to humidity it bends in the opposite direction as the suspended portion of the circuit. In another embodiment, additional hygroscopic material is added to the circuit, and/or the polyimide insulating layer or the coverlayer are selectively removed, so that the net bend in the suspended portion of the circuit over humidity is reduced, ideally to a condition of zero or close to zero net bending.

The present invention pertains to the use of at least one abasic modification within the first 8 nucleotide positions of the 5′ region of the antisense strand of a small interfering nucleic acid (siNA) molecule for reducing off-target effects. Provided are suitable modified siNAs, compositions and methods for producing respective siNAs, as well as kits comprising respective siNAs.

The invention relates to a composition for inhibiting the expression of a target gene in a eukaryotic cell by RNA interference, the composition comprising a genetic construct and the target gene being introduced into the eukaryotic cell by means of said construct, and the construct having a first target gene and a first siRNA tag. The invention also relates to a composition for inhibiting the expression of one or more target genes in a eukaryotic cell by RNA interference. The composition comprises at least two genetic constructs and the target genes are introduced into the eukaryotic cell by means of said constructs, a) the first construct containing a first target gene and a first siRNA tag and b) the second construct containing a second target gene and a second siRNA tag, and the first and the second siRNA tag having different nucleic acid sequences. The invention finally relates to a method for inhibiting the expression of a target gene in a eukaryotic cell. Said method comprises the following steps: a) providing at least one eukaryotic cell, said cell being capable of RNA interference, b) transfecting the cells with a composition according to the invention and c) introducing at least one siRNA that is complementary to a siRNA tag of a transfected construct to inhibit the expression of the target gene that forms a transcription unit together with the siRNA tag.

A disk drive suspension has a mount plate, an outwardly tapered load beam supported by the mount plate and having a base portion, a hinge portion, a beam portion having a first face with turned edges and a flexure supported by the beam portion distally of said beam portion face, and a generally congruent tapered stiffener having a central portion of a given height that is concave and open to the beam portion. The stiffener has left and right flange portions extending laterally from the central portion to the beam portion upturned edges to locate said central portion centrally on the beam portion face.

A mounting assembly for securing a disk drive to a frame of a computer is provided herein. The mounting assembly includes three rigid mounts and a single flexible mount. Each rigid mount rigidly secures the drive housing to the frame and prevents degradation of performance of the disk drive. The flexible mount diminishes the level of vibration transferred from the frame to drive housing. Further, the flexible mount facilitates flexing of the drive housing intermediate the flexible mount and the rigid mounts. This reduces the effects of a shock pulse to the disk drive and inhibits head slap between a transducer head and a storage disk.
摘要:
In a method for automatically gutting fish of the catfish species, the belly cavity is opened around the anal orifice either before or after opening the gills by severing the gullet and opening the blood stream, and the contents of the belly cavity are removed by pushing these from one of the openings of the cavity out of the other. In a machine for carrying out this method, the fish are conveyed sideways by a recessed conveyor. The belly cavity is opened in the vicinity of the anus by separating away the cartilaginous plate carrying the ventral fins. The contents of the ventral cavity are removed by a rotary body rotating synchronously with the conveyor and having tools successively arranged in a cantilevered helix around its circumference which comprise a clearing tool with scraping segments, a brush tool, a high-pressure spray device and a cutting tool for slitting open the belly cavity along its length.
