The cutting device comprises a carrier element, and first and second electrodes each connected to the high frequency generator. Each electrode has a proximal portion attached to the carrier element and an elongated distal leg portion which terminates in a distal end. An insulation element connects the distal ends to each other with predetermined spacing between them. The elongated segments oppose each other and are aligned to be co-linear with each other along the cutting direction.

    摘要: A device for removing material from a workpiece, in particular for removing a hard substance, such as tooth enamel or dentine from a tooth, or for removing ceramic materials, has a laser for irradiating the workpiece in a locally limited ablation area where material is removed, and a handling part (1) which receives the laser or is connected thereto by an optical fiber element or by a mirror arrangement. The handling part (1) is used to position the laser beam (3) in the ablation area and has a distance measurement device (11 to 15, D1, D2) to monitor the depth of material removal. While the material is being removed, the distance measurement device (11 to 15, D1, D2) measures the distance to the workpiece surface in the ablation area and therefore the depth of material removal by means of the material-removing laser or of a measurement beam (11) generated by another laser.

    摘要: Disclosed is a semiconductor memory having a hierarchical bit line and/or word line architecture. In one embodiment, a memory having a hierarchical bit line architecture, particularly suitable for cells smaller than 8F.sup.2, includes a master bit line pair in each column, including first and second master bit lines with portions vertically spaced from one another. The first and second master bit lines twist with respect to one another in the vertical direction such that the first master bit line alternately overlies and underlies the second master bit line. A plurality of local bit line pairs in each column are coupled to memory cells, with at least one of the local bit lines coupled to a master bit line. In other embodiments, hierarchical word line configurations are disclosed including master word lines, sub-master word lines, and local word lines, electrically interconnected to one another via either switches, electrical contacts, or electrical circuits.

    摘要: Disclosed is a semiconductor memory employing a hierarchical bitline architecture which allows for a widened master bitline pitch as well as low bitline capacitance. In an exemplary embodiment, the memory (30) includes a plurality of memory cells (MC) arranged in rows and columns for storing data. Each column has at least one sense amplifier (SA.sub.i), at least one pair of master bitlines (MBL.sub.i, MBL.sub.i ) operatively coupled to the sense amplifier, and at least two pairs of local bitlines (LBL.sub.1i, LBL.sub.1i , LBL.sub.2i, LBL.sub.2i ), coupled to memory cells and selectively coupled to the sense amplifier. At least one of the local bitline pairs is selectively coupled to the sense amplifier via the master bitline pair. Each master bitline pair has a length shorter than a column length, and the master bitlines are arranged in an interleaved configuration. The pitch of at least a portion of at least some of the master bitlines is greater than the local bitline pitch. The master bitlines may be arranged in either folded or open configurations. The master bitline pitch may be about twice the local bitline pitch.

    摘要: The invention contemplates scanning-microscope display of plural observed parameters of an examined specimen, where the parameters derive from flying-spot light-exposure of the specimen, and where at least one of the observed parameters is outside the wavelength range of the flying-spot. In some illustrative embodiments, at least one of the observed parameters is sensed by a detector which uses the same scanning optics as the flying-spot, and in other embodiments other techniques of synchronization are involved. The disclosed embodiments also provide for selective arrest of scanning to enable such factors as fading fluorescence and spectrum analysis to be ascertained strictly for a surface occlusion, impurity or other anomaly of interest.
