Abstract: A spraying device (10) comprises a nozzle casing (12) surrounding an interior which holds a nozzle block (14) and a conduit coupler (16) therein. The nozzle block (14) and the coupler (16) are axially aligned, a front wall (62) of the coupler (16) facing a rear wall (72) of the nozzle block (14). The nozzle block (14) and the coupler (16) are relatively rotatable, enabling the front wall (62) of the coupler (16) to rotate relative to the rear wall (72) of the nozzle block (14). A plurality of spray pattern forming apertures (20,22,24,26) pass through the nozzle block (14), from the rear (72) to the front wall (74) thereof. A fluid passage (28) in the coupler (16) has a liquid outlet (18) on the front wall 62 of the coupler (16) that is sealingly disposed against the rear wall (72) of the nozzle block (14), eccentrically to the axis of rotation of coupler (16) in a manner which permits the liquid outlet (18) to be brought into fluid communication with any one of the spray generating apertures (20,22,24,26). A comparatively large cylindrical bore (60) which extends along the axis of the nozzle block (14) forms a chamber (76) which is open to the front wall (62) of the nozzle block (14) and is in fluid communication with one of the apertures. The chamber (76) is designed to interchangeably hold therein either a nozzle insert (84) which serves to generate one particular type of spray or a turbo assembly (102) for generating a turbo or rotating liquid jet.

Abstract: A digital audio signal is subjected to predetermined modulation using a predetermined carrier, and thereby the digital audio signal is converted into a modulated digital audio signal. An FM audio signal is generated. The modulated digital audio signal and the FM audio signal are combined into a composite audio signal. The composite audio signal is superimposed on a high-frequency bias signal, and thereby the composite audio signal is converted into a final modulated audio signal. The final modulated audio signal is recorded into a magnetic tape. A predetermined basic signal is generated. The predetermined carrier and the bias signal are generated from the basic signal. The predetermined carrier and the bias signal have a predetermined frequency relation which is chosen in dependence upon a frequency of beats caused by cross modulation between the modulated digital audio signal and the bias signal.

Abstract: The present invention provides a dual-action tablet composi­tion comprising:
     (a) an outer tablet comprising a first dose of active ingredient dispersed in a pH independent hydrophilic polymer matrix; and   (b) an inner tablet comprising a second dose of active ingredient in a rapidly disintegrating excipient base.   
     This dual-action tablet is especially efficacious for those active ingredients which half lives of less than two hours and which experience decreased absorption efficiency in the lower gastrointestinal tract. Among the preferred dual-action tablet composition is one wherein the active ingredient in both the inner and outer tablets is guaifenesin. Upon administration, the outer tablet provides a controlled release of the active ingredient while the inner tablet gives a second dose of active ingredient after the outer tablet has partially dissolved.

Abstract: An optical print head comprises light-emitting elements (3) disposed on a substrate (2) having a light-emitting surface opposite to the substrate (2), and a transparent mold member (11) covering the light-emitting elements (3) and the surface of the substrate (2) at the area surrounding the areas where the light-emitting elements (3) are disposed. The surface of the mold member (11) is more receded toward the substrate (2) at the neighboring area than at the areas where the light-emitting elements (3) are disposed and covered with the mold member (11). Because the light-emitting elements (3) are covered with the mold member (11), any corrosion thereof is prevented. Moreover, since the mold member (11) is transparent, any light emitted from the light-emitting elements (3) is not absorbed. Furthermore, degradation in recording quality due to scattering and multiple reflection of the light emitted from the light-emitting elements (3) toward the inside of the transparent mold member (11), and unnecessary leakage is avoided, so that an optical print head with a high recording quality is obtained.

Abstract: Semiconductor memory having non-volatile memory cells which can be programmed and erased electrically (EEPROM) by means of tunnel current and which contain a floating-gate transistor. The memory cells are arranged in memory cell groups each containing n rows and in m columns, n cells being connected in series and this serial connection forming the bit line for the columns of a cell block and the control gate of m adjacently situated memory cells being common to a row of the cell block and forming the word line for the row of the memory cell group. The regions (injector regions), situated below the gate oxide, of the n cells of a column of a memory cell group are interconnected and thus form a programming line which is separated from the source and drain zones of the floating-gate transistors. On the one hand, this results in a reduction of the programming voltage to be applied since the programming voltage applied to each cell of a column is independent of the programming state of the cells in a column. Furthermore, this makes it possible to randomly program the cells. <IMAGE>

IPC: H04H60/04
Filed: 1991-02-22
Abstract: In order to include a break slot in a broadcast video signal, the signal is first fed through a RAM recorder (24) having a variable delay. Reading of the signal from the RAM recorder (24) is controlled in such a manner that the delay produced by the RAM recorder is reduced from an accumulated value. After the delay has been reduced by a desired amount, reading out of the signal from the RAM recorder (24) is inhibited until the delay has increased again to no more than the accumulated value, thereby to produce a break slot having a duration no more than the reduction of the delay produced by the RAM recorder. The reduction of the delay produced by the RAM recorder (24) may be brought about by: skipping the reading of unwanted portions of the signal stored in the RAM recorder (24), by feeding the signal through a fixed delay RAM recorder (14) before feeding it through the variable delay RAM recorder (24) and viewing the signal before it is fed through the fixed delay RAM recorder (14) to identify portions of the signal to be edited out; or by reading from the variable delay RAM recorder (24) at a speed greater than the speed at which the signal is written to the variable delay RAM recorder (24).

Abstract: A voltage control (22) controls the voltage applied between an anode (12) and a cathode filament (14) of an x-ray tube (10). A filament control (16) controls the amount of current fed through the filament. A voltage controlled oscillator (42) and counter (44) monitor the magnitude of a tube current (24) flowing between the cathode and the anode to generate x-rays (26). A microprocessor (50) calibrates the filament current such that the filament current value stored in a filament current look-up table (122) for each selectable tube voltage and tube current combination actually produces the selected tube current. The filament current is set (60) to a small current value and progressively incremented (66) until a tube current (24) is monitored (64). To calibrate each selectable tube voltage, tube current combination, the filament current is incremented from this initial current flow or emission point (52) and the resultant tube current is compared (98) with the selected tube current. A substantial portion of the filament current values stored in the filament current look-up table are determined in this way and the rest are determined by interpolation (140).
