Patent EP-0531196-A2 (EP)
Inventor: GOULET RICHARD
IPC: F23D14/42
Filed: 1992-09-01
Abstract: A multi-part oxy-fuel cutting tip has mixture outlet passages formed by swaging the tip skirt to form grooves. The grooves then cooperate with the tip core to form the outlet passages when the skirt is placed over the tip core. Oppositely directed circumferential inlet passages for the preheat oxygen and fuel promote rapid mixing while producing a non-rotating mixture flow. In addition, the sectional areas of the outlet passages decrease in the flow direction. These features promote the rapid creation of a laminar mixture flow.

Abstract: A method and apparatus for determining the thickness of an interfacial oxide film intermediate to a polysilicon layer of a first conductivity type and a silicon substrate of a second conductivity type supporting a p-n junction. Radiant energy, preferably in the form of light, is directed on to the top surface of the polysilicon layer thereby stimulating carriers which concentrate at the interfacial oxide film, allowing the excited carriers to diffuse across the oxide film, and creating a short circuit, the magnitude of which is inversely related to the thickness of the interfacial oxide film.

Abstract: A hard disk drive having an actuator assembly in which the armstack structure (5) comprises only load beams (5a). The load beams (5a) are assembled by stacking on a tubular member (9a) along with the movable member (5b2) of the actuator motor (5b1,5b7,5b8), or other actuator drive mechanism, and after alignment are secured to the tubular member (9a). This actuator structure is applicable to both rotary and linear actuators in disk drives. In the rotary actuator structure, the tubular member (9a) or hub is journaled (9b,9c) in the base (1) of the drive for rotation about the axis of the tubular member (9a). In the linear actuator structure, the tubular member, being fastened to the moving part of the linear drive mechanism, linearly moves with that mechanism. The load beams (5a) and the movable actuator drive mechanism (5b2) are secured to the tubular member (9a) by a ball swaging operation which forcibly expands the tubular member (9a) into secure frictional engagement with the items assembled thereon to thereby integrate the assembly with a single ball swaging pass through a single member.

Abstract: A chirped grating surface emitting distributed feedback semiconductor laser device ( 10 ) includes a P-side ohmic contact ( 28 ) and an N-side ohmic contact ( 36 ). A potential difference is applied across these contacts to create an electric field that induces a stimulated emission of coherent photon radiation. The coherent photon radiation produced by the stimulated emission process is incident upon a linearly varying, second order chirped grating surface ( 29 ). An output beam, directed normal to a chemically etched output window ( 38 ), is produced by a first order diffraction of photon radiation from the chirped grating surface ( 29 ). The output beam has a non-uniform longitudinal mode near-field output intensity profile and an non-abrupt longitudinal mode near-field phase, both due to a reduced destructive interference interaction in a second order diffraction of photon radiation along the grating surface ( 29 ). The output beam also has a desired single lobed longitudinal mode far-field output intensity profile. Moreover, the device achieves a 20% power efficiency due to the reduced destructive interference in the second order diffraction.

Abstract: A drop-on-demand ink jet print head (9) has an ink chamber (22) coupled to a source of ink (11), and an ink drop orifice (103) with an outlet (14,14a,14b). An acoustic driver (36) produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop orifice and outlet (14,14a,14b). The driver is driven with bipolar drive pulses (100) having a refill pulse component (102) and an eject pulse component (104) of a polarity which is opposite to the refill pulse component (102). The refill and eject pulse components are separated by a wait period (106). The drive pulses may be adjusted to minimize their energy content at a frequency corresponding to the dominant acoustic resonance frequency of the ink jet print head (9). This will accelerate drop breakoff, optimize drop shape and minimize drop speed variations over the range of drop printing rates. The size of the ink drops may be varied, such as by driving the acoustic driver (36) with varying drive signals, preferably utilizing individual or combinations of a plurality of bipolar drive pulses (100). The ink jet printer of the present invention may be used to print with a wide variety of inks, including phase change (hot melt) inks to achieve high print quality at high print rates.

IPC: H04H60/04

Abstract: An electrical circuit arrangement for processing analog electrical signals, particularly in the acoustic low-frequency range, is generated by the fact that the output signals of first function elements (f1, f3, f5, f7, f9) are selectively connected to electric conductors of a bus (13) without hardware change in accordance with their circuits by means of networking elements (d). The conductors of this bus (13) are then selectively connected to the inputs of second function elements (f7, f9, f11), selected by networking elements (m). The connecting is effected by means of a number of analog multiplexers (m) and a number of analog demultiplexers (d), using a current bus, the input of each demultiplexer (d) and the output of each multiplexer (m) following or, respectively, preceding the output (a) or, respectively, the input (e) of the relevant function element (f1, f3, f5, f7, f9, f11) of the relevant circuit module (1, 3, 5, 7, 9, 11). Different circuit arrangements can thus be implemented on standardised boards. Due to the freely selectable networking, it is possible to check individual and interconnected function elements for their operability by connecting a test source and a test detector. An advantage of the circuit arrangement according to the invention lies in the fast and unproblematic change in the networking of the function elements (f1, f3, f5, f7, f9, f11) and in the rapid modification of the function circuits which can be achieved by means of the circuit arrangement. There are no hand-wired customer-specific circuit arrangements, since standardised boards can also be used in these cases. <IMAGE>
