Patent EP-0357222-A2 (EP)
Inventor: LUKER NORMAN ELVOY
IPC: B29C48/04
Filed: 1989-07-27
Abstract: In an apparatus for producing particles of thermoplastic material by extruding material (23) in a plastic state through orifices (18) in a die plate (12) and thereafter cutting the extruded plastic material into crumb (23′) upon exit from the orifices, an air supply (22) is coupled to a cutting chamber (20) for providing a stream (21) of air across the face of the die plate to cut and convey the crumb away from the orifices. The cutting chamber is arranged to include a restricted throat (24) having an exit area in close proximity to the orifices and a further portion for providing an accumulation zone adjacent the orifices, the accumulation zone (20′) having a cross-sectional area which increases from the exit area of the throat to a product discharge zone (29) remote from the orifices in a downstream direction.

Abstract: A superconductive transistor comprising a substrate, an oxide superconductor layer epitaxially grown on said substrate, a source electrode, a drain electrode, said source electrode and said drain electrode being arranged on said oxide superconductor layer, an insulator film epitaxially grown on said oxide superconductor layer and located between said two electrodes and a gate electrode located on said insulator film, wherein the following relationship is established, 
d c  ≦ √ (2εV f )/n,   
wherein d c  represents the thickness of the superconductor layer, ε represents the dielectric constant of the superconductor layer, n represents the carrier density of the superconductor layer and V f  represents the voltage that corresponds to the forbidden band width of the superconductor layer. Since a superconductive transistor according to the invention controls the superconductive transport current that runs through the superconductor layer with zero resistance, it functions as a switch that can accommodate electric current far greater than any known device.

Abstract: In a transmitter, a modulator (1) switchably operates on one of two modes of operations, that is, in a first mode of the operation, such as an offset QPSK, FSK or π/4shift QPSK, an amplitude of an output signal of the modulator does not become zero at any instant, and in a second mode of the operation, such as two-phase FSK or four-phase PSK, the output signal of the modulator is 100% amplitude-­modulated or 180 phase-modulated. 
     The operation mode is switched by changing the mode of the parallel input signals to the modulator, where the parallel signals have been converted from a serial input data signal to be transmitted. After the first mode operation is switched to the second mode operation the output signal is interrupted preferably on a first moment that the amplitude of the output signal becomes zero, as well as, before the second mode operation is switched to the first mode operation the output signal is resumed preferably on a second moment that the amplitude of the output signal is to become zero. The interruption of the modulated output signal may be done by cutting theiocal frequency or modulated signal, or by the parallel input signals. Thus, spurious wave is not generated on the transition of interrupting or resuming the modulated transmittal wave, and the period of the interrupting can be short enough.

Abstract: Die Messung der Diffusionslänge von Minoritätsladungsträgern in einem Halbleiterkristallkörper wird dadurch ermöglicht, daß Vorder- und Rückseite (9, 10) der Kristallscheibe (1) jeweils mit einem Elektrolyten (4, 5) in einer Meßhalbzelle (2, 3) in Kontakt gebracht werden und auf der Vorderseite (9) der Scheibe eine sperrende Raumladungszone erzeugt wird. Die Vorderseite wird mit Licht (11) mit einer Wellenlänge λ> 800 nm bestrahlt und der Vorderseiten-Fotostrom I1 der dabei erzeugten Minoritätsladungsträger gemessen. Aus dem Fotostrom I1 kann mit Hilfe einer mathematischen Gleichung die Diffusionslänge (L) berechnet werden; bei punktförmiger Bestrahlung und Rastern über die Kristallscheibe (1) erhält man die örtliche Verteilung von L. Durch die Wahl einer Lichtquelle (11) mit einer Wellenlänge λ> 800 nm sind Diffusionslängen L < 150 µm meßbar. Das Verfahren kann zur Bestimmung der Qualität von Halbleiterkristallen angewendet werden.

Abstract: The inventive quantum well opto-electronic devices of cavity length L C  comprise, in addition to a "gain" section (20), a "loss" section (21) that is optically coupled to the gain section (20) but electrically substantially isolated therefrom. Through change of the electrical bias on the loss section (21) the modal gain of the cavity can be changed. Devices according to the invention are useful in a variety of applications. Exemplarily, by making (in an inventive laser) L C /L A  greater than about 20 (L A  is the length of the loss section) and making the electrical isolation between the gain section (20) and the loss section (21) greater than about 3kΩ, fast amplitude modulation of the laser radiation is possible. By applying appropriate AR coatings to the cavity of an inventive device, a fast variable-gain optical amplifier can be made. Finally, an inventive laser can be switched electrically between two widely spaced wavelengths, the wavelength difference being at least 10 nm. This makes possible use of inventive devices in apparatus such as information storage systems, information processing systems, and communication systems. Methods of operating such apparatus are also disclosed.

Abstract: A skew processing circuit 33 includes two line buffers, a skew processing type line buffer 331 and an original type line buffer 332, and a write/read control circuit 333 for controlling the two line buffers. The write/read control circuit 333 is a control circuit for writing a given image data in the line buffers 331, 332 in single lines and selectively reading the data written in the two line buffers 331, 332. When an image data is written in the original type line buffer 332, addressed are sequentially written from the head address 0. On the other hand, when the image data is written in the skew processing type line buffer 331, a write start address RH0 is determined in correspondence with a skew angle, and the write start address RH0 is shifted in each line to discard the head portion of the image data by specified dots (specified addresses). Thus, by controlling the writing of data in the two line buffers 331, 332 and reading data from them, an image in an arbitrary area can be processed into the skew with an arbitrary angle.

Abstract: A method of correcting for the impairments of phase jitter and frequency offset imposed by a transmission medium and of a clock frequency difference between a transmitting and a receiving multicarrier modem is disdosed. The method comprises two modes : a training mode that uses pilot tones, and a data mode that uses random data modulated onto many carriers. During the training mode the frequencies of the phase jitter are estimated, and the parameters of a correcting signal are initialized; during the data mode the correcting signal is used to compensate for the impairments, and then is updated from an estimate of the phase error.

Abstract: The present invention relates to a display (10) having the capability to emit light and form images viewable from both the front (12) and back (14) of the display. The images displayed are seen from both the front (12) and back (14) of the display (10) and appear differently to the front and rear viewer. Electronic shutters (16, 18) are placed between the display (10) and both the front and rear viewers so that they can be flashed on and off fast enough to provide a stable image appearing to each viewer. The shutters also flash slow enough so that display data can be rewritten to provide each viewer with a correct image. The correct image can be either the corrected image of that image seen by the opposing viewer, or a completely separate image. In this way, simultaneous images appear to both the front and rear viewer. These images can be the same or different even though they appear from the same display (10). The use of electronic shutters on displays emitting light from both the front (12) and rear (14) of the display (10), provide the display with multiple functions not possible on conventional displays.
