IPC: H01S5/227
Filed: 1986-06-26
Abstract: An improved buried heterostructure semiconductor laser comprises high resistive burying layers positioned at both sides of an active region so that the high speed modulation is possible to be performed and the higher quantum efficiency is obtained for the reason why the capacitance and leakage current are diminished. A further improved buried heterostructure semiconductor laser comprises spacer layers between an active region and respective high resistive burying layers so that the reliability is maintained to be high for the reason why the diffusion of an impurity is avoided from the respective high resistive burying layers to the active region. Further, an improved process for the fabrication of a buried heterostructure semiconductor laser comprises steps of forming mesa stripe including an active region on the upper portion of a double heterostructure and forming high resistive burying layers to be positioned at both sides of the active region.

Abstract: High-speed bipolar signals transmitted along standard twisted pair (17) telephone wiring are subject to InterSymbol Interference which is corrected by an equalizer circuit (10) that is operably responsive to predetermined parameters of bipolar signals detected at the secondary (21) of a line transformer (15). These parameters are input to a control logic circuit (11) which includes several stages, each producing a set of past dependent logical control signals which are input to corresponding equalizer tap circuits (25) (26) (27) having outputs connected to a common output bus (40). Each tap circuit (25) (26) (27) includes an integrator (46) that is incrementally charged and discharged by an electronically switched capacitor (51). A tap weight voltage output from each integrator (46) is subsequently summed directly or inversely by a second switched capacitor (52) under control of the logical input signals. And, an equalizing signal output from the second capacitor (52) is coupled through a buffer amplifier (41) to the line transformer (15) where it is added to the incoming signal and allows eye diagram monitoring directly at the transformer (15).

Abstract: A heterojunction bipolar transistor having excellent high-frequency characteristics is manufactured by forming a semi-insulating semiconductor layer on a collector (or emitter) layer, removing a part of the semi-insulating semiconductor layer to form a cut portion so that the collector layer is exposed at the cut portion, growing a base layer on the semi-insulating semiconductor layer, on a slant wall of the cut portion and on the exposed part of the collector layer, and growing an emitter (or collector) layer on the base layer. A base layer may be preliminary formed on the semi-insulating semiconductor layer before forming the cut portion. Energy band gap of the emitter is greater than that of the base.

Abstract: An inline dispersal valve is constructed with a chamber into which a material to be dispersed into a fluid stream may be inserted. A first fluid deflector is used to direct fluid away from the fluid stream into the chamber to permit the fluid to absorb the dispersant, and a second fluid deflector, oppositely facing, that directs the fluid back into the fluid stream after it has passed through the chamber. The bottom of the chamber has a pair of openings in line with each other which have an axis that is substantially normal to the axis of the fluid flow in a main stream.

Abstract: Methods are disclosed for operating receiver devices which take serial data patterns off a high speed synchronous serial transmission media and convert the data to parallel pattern outputs. According to the invention, each device operates under a "permission to capture" data protocol which allows a given receiver to operate at the byte rate of the transmitted data. Devices using the disclosed methods may be operated individually or in a cascaded fashion. In either mode, by enabling the receivers to transfer high speed data at the transmitted pattern byte rate, as opposed to the bit rate, the reliability and capacity of the receivers to field high speed data is enhanced. In addition, the disclosed methods obviate the need for receivers operating in a cascade mode to "know" their position in a cascade chain. As a result the operating simplicity and reliability of devices that employ the disclosed methods is further enhanced.

Filed: 1987-09-02
Abstract: The conditions of the access request signals of the relevant slave processors are stored at a first time. After the storage of at least one of these signals, the master processor prepares to issue the access authorisation, and a selection logic selects one of the requesting slave processors by referring to the stored request signals. Once the master processor has issued the access authorisation, the latter is transferred at a second time to the slave processor selected by the selection logic. The access request conditions are stored again only when the access authorisation is returned from the selected slave processor to the master processor. <IMAGE>

Abstract: A single-mode transmission optical fiber may have a bandwidth much greater than that necessary to transmit a desired predetermined maximum data rate. The single-mode fiber (11a, 11b) is connected to a band­width limiting device (14,14ʹ) comprising the serial combination of an input optical fiber (16,16ʹ), a mode converter (18,18ʹ,22) and multimode fiber (20,20ʹ). If the multimode fiber is capable of propagating two modes, for example, the mode converter converts the LP01 signal from the transmission fiber to the LP01 and LP11 modes. These two modes propagate at different speeds through the multimode fiber. Means (12,12ʹ,36) connected to the output end of the multimode fiber (20,20ʹ) detects the two modes. If the time delay difference Δτ between the two modes is small with respect to the width of a pulse in the transmitted pulse train, the pulse train will be detected without distortion. Transmission at a higher data rate causes Δτ to be large with respect to pulse width. Thus, a transmitted pulse causes the generation of a false pulse, whereby operation at the higher data rate is impossible. Also disclosed are methods of making suitable mode converters.

Abstract: Two identical test patterns (30) are overlaid upon each other on a planar substrate of semiconductor material A. Each pattern consists of a plurality of spaced parallel lines. The lines are arranged in two sets of horizontal lines (32,34) and two sets of vertical lines (36,38). The line/space periodicity is known. The lines of the two test patterns are made of two different materials, B and C, respectively. Thus, the target pattern formed by the two test patterns and the substrate has four reflecting regions defined by the different layers in each region: A, AB, AC and ABC. Adjacent the overlaid patterns are four macro-zones each containing a different one of the four layers, A, AB, AC and ABC. Each macro-zone is illuminated by a broad spectrum light, such as that from an incandescent lamp, and the reflected light intensity from each macro-zone is measured. Then, the reflected (or transmitted) light intensities from the two sets of horizontal lines are separately measured, as are the reflected intensities from the two sets of vertical lines. One then can calculate both the horizontal and vertical overlay error from the known periodicity and the measured light intensities.
