Abstract: The apparatus comprises a thermal print head comprising a row of electrodes 22 embedded in a layer 19 of insulating material sandwiched between two blocks 20, 21 which provides a common return conductor for currents from source 26. Each electrode is individually connectable via switches 25 to the source 26. The transfer ribbon 14 comprises a resistive layer 23 which is electrically contacted by both the electrodes 22 and the return conductor 20 and an inking layer 24 which contacts the record sheet 15. In use the head is moved along the ribbon 14 in the direction of the arrow 28 and the switches 25 selectively actuated to cause thermal transfer of ink from the layer 24 to the record sheet 15. The transfer is caused by heat generated in the layer 23 when local currents are established herein between the electrodes 22 and the return conductor 20.

Abstract: A semiconductor wafer into which devices such as an integrated circuit is to be formed is gettered by regions in the wafer activated by a laser beam. The laser beam is directed onto the surface of the wafer on the side or opposite to that where the devices are to be formed. The power input to the laser is controlled such that the surface temperature of the region of the semiconductor wafer where the laser beam is applied first reaches the melting point of the material, and the melting commences. Then the temperature in the melt rises above the melting temperature, but stays below the boiling temperatαre of the material of the wafer. A superheated melt is formed. The result is that the solid-liquid interface moves deep into the material. The position of the melt is directly under the laser beam. The solidified material is positioned behind the beam as the beam scans the wafer. A depression is formed under the beam while the material rises behind the laser beam.

Abstract: A data display and management system includes a microprocessor (10) whose functions are implemented by instructions in data from a directly connected main memory (48). A mass data storage memory (52) is connected to the main memory (48) and has permanently stored instructions set therein for the microprocessor (10). A display control system which operates asynchronously with the microprocessor includes a display controller (16), display memory (96, 104), character memory means, and a visual character attribute generator (94). By linking one or more row attribute bytes, or pointers, to each row of characters stored in the display memory (96) the display controller (16) performs character and row manipulation on a display device without transferring whole blocks of data in the display memory (96). Multi-region display segmentation into horizontal and vertical split regions, smooth or discrete scrolling of individual regions, and various editing functions are achieved by modifying the associated display memory pointers.

Abstract: A compressor and its external-rotor drive motor are arranged on a common stationary shaft in a unitary housing. On the end of the stationary shaft which is away from the compressor, a friction pump is mounted for pumping lubricant from a supply in the unit housing into an axial canal drilled in the stationary shaft. The impeller of the friction pump consists of a hollow cylinder which is coupled to the external rotor. The hollow cylinder is received in a pump housing which has an annular space between an inner and an outer housing part into which the hollow cylinder extends, forming an inner and an outer gap. The two gaps are in communication with each other and each contains at least one constriction which forces oil carried by rotation of the hollow cylinder past openings in the inner housing into the axial canal.
