    摘要: The buffer circuit of the invention converts TTL level input signals to CMOS level output signals. The buffer circuit has three inverter stages, in which the output signal of one stage is positively fed back, in order to achieve complete modulation. Because of a current limiting circuit, the current consumption of the buffer circuit does not exceed a defined value. Despite a high switching speed, the power consumption of the circuit is low.

    摘要: Disclosed is a semiconductor memory (18, 20, 100, 200) having a hierarchical bit line architecture including local bit lines (LBL.sub.1, LBL.sub.2) on a lower fabrication layer, coupled to memory cells (MC), and master bit lines (MBL) on a higher fabrication layer, each coupled to an associated sense amplifier (SA.sub.i). Local bit lines disposed in any given column are coupled to different numbers of memory cells, i.e., the local bit lines have different lengths (L1, L2) over the memory cells. A hybrid configuration is preferably employed in which one local bit line (LBL.sub.1) in a column is directly coupled via a switch (25.sub.1) to an associated sense amplifier, whereas the other local bit lines in the column (LBL.sub.2 -LBL.sub.4) are operatively coupled to the sense amplifier via the master bit line. The different local bit line lengths are preferably selected such that total bit line capacitance with respect to any of the memory cells is substantially equalized, thereby improving data retention time for the memory.

    摘要: A process for the optical spatially resolved determination of density distributions in biological tissues includes as a first step irradiating a biological tissue by directing a locally confined beam of electromagnetic radiation at an incidence position of the tissue; keeping the incidence position fixed; determining the thickness of the tissue being irradiated; and sensing and recording the directly transmitted radiation component and the scattered radiation component in a spatially resolved manner over a defined spatial angle. As a second step, the incidence position is changed and the first step is repeated. As a third step, the second step is repeated a number of times to obtain a reconstructive representation of the tissue through which the radiation has passed, based on the spatially resolved recordings of the transmitted and scattered radiation components and the tissue thickness as determined in each repetition of the first step.

    摘要: A device for the removal of tubular fabric from a circular knitting machine comprises a machine frame, a driven take-up roller around which the tubular fabric is partially wound, a winding rod for winding the tubular fabric and two bearings at the ends of the winding rod. The bearings of the winding rod are arranged in levers which are pivotally mounted on the machine frame for pivoting from an operating position to a removal position. In the operating position, the winding rod can be locked in position by wedge-shaped locking elements. In the removal position, the winding rod can be removed from the machine frame simply and easily.

    摘要: A machine for kneading dough portions into a round shape is provided with a kneading drum adapted to be driven in the peripheral direction and in the direction of an axis. The kneading drum is concentrically enclosed by a compartmented drum adapted to be rotatingly driven in a peripheral direction and has kneading chambers open radially outwardly and radially inwardly towards the kneading drum. Furthermore, the compartmented drum has, looped around a portion of its periphery, in a belt contact zone, a kneading belt which presses the dough portions against the kneading drum and prevents them from falling out of the kneading chambers.The kneading belt can be driven by a positive drive which is independent of bearing forces between the kneading belt and the surface of the compartmented drum, whereby the kneading belt no substantial bearing forces on the belt contact zone of the compartmented drum.
