Abstract: InGaAs photodiodes are produced on an epitaxial InP wafer having an InP substrate, epitaxially-grown layers and an InGaAs light-sensing layer. An insulating-protecting film of Si x N y or of SiO x is deposited thereon with openings selectively in the epitaxial wafer. Compound semiconductor undercoat layers of a compound semiconductor are then grown having a band gap which is narrower than InP on the InP window layers at the openings by utilizing the insulating-protecting film as a mask. A p-type impurity is diffused from a solid source or from a gas source through the undercoat layers and the epitaxial InP layer into the InGaAs light-sensing layer.  P-electrodes are formed on the undercoat layers and the undercoat layers are then etched by utilizing the p-electrodes as a mask. Alternatively, the undercoat layers may be shaped by selective etching in the form of p-electrodes and forming the p-electrodes on the undercoat layers.

Abstract: The present invention relates to a process and apparatus for the preparation of urea, and in particular for urea obtained from ammonium carbamate formulated from carbon dioxide and ammonia at a pressure of about 125 bar to about 350 bar in a urea synthesis solution in a urea reactor. The reactor defines a horizontally arranged condensation zone and contains a heat exchanger. According to this process, NH3 and CO2 are supplied to the reactor and are largely absorbed into the urea synthesis solution. A substantial portion of the heat formed in the condensation is discharged by means of the heat exchanger. The residence time of the urea synthesis solution in the reactor preferably is selected so that at least about 85% of the theoretically obtainable amount of urea is prepared. Thereafter, the urea synthesis solution can be processed into a urea solution or solid urea.

Abstract: A pear processing method and apparatus  is provided which includes several mechanisms  for properly orienting the pear prior to coring, peeling and seed celling of the pear.  Each pear is tumbled between a pair of orienting rolls to a position wherein the stem of the pear is  oriented  downwardly. Whiskers  on one of the rolls speed up this orienting of the pear. A friction clutch on the other roll helps maintain the pear in its proper position, once the proper alignment has been attained.  The pear is dropped downwardly into a transfer cup having four resilient  fingers which tend to orient the pear.  The pear is then pushed out of the   transfer cup downwardly into a feed cup having  a   concave  receptacle for centering  the stem of the pear and three upwardly  extending arms which grasp and center the blossom end of the pear. The pear is then  transferred to a station wherein the pear is cored and thereafter peeled and seed celled  simultaneously. The stem and blossom are also trimmed.  The pear is  thereafter passed into a slice cup having a design which more effectively separates the waste from the processed pear.

Granted: 2001-01-02
Abstract: A map editing device capable of easily supplementing insufficient information and easily measuring again an object that has changed.  An image, a perspective projection map, a projection center and a projection angle are displayed in superposition.  When a user manually changes the projection center and the projection angle, a perspective projection map after this change is generated and displayed.  When a per-spective projection map capable of obtaining insuffi-cient information is determined, an imaging condition capable of obtaining the insufficient information can be determined based on the projection center and the projection angle at that time.  The insufficient information can be easily supplemented if the arrange-ment is so made as to acquire images conforming with the imaging condition.  The condition necessary for re-measurement can be determined.

Abstract: The invention concerns traffic information acquisition systems for vehicles, which systems have a first opto-electrical transceiver on the vehicle side and a second opto-electrical transceiver provided at predetermined locations in traffic lanes. The first transceiver emits a first signal and receives and decodes a second signal from the second transceiver. The second transceiver receives the first signal from the first transceiver and sends back a coded, second signal to the first transceiver.  The first transceiver is in the form of a reflection-operating time-distance measuring device. The emitted optical distance-measuring pulse signal is simultaneously the signal received by the second transceiver.  The second transceiver emits the second signal after a delay time following reception of the first signal. The delay time should be longer than the maximum amount of time required for a distance measurement.  It is thereby ensured that a signal from the second transceiver is not erroneously interpreted as a signal reflected by a target.

Abstract: Within a differential detection demodulator, a received signal is first quantized by a limiter amplifier and then subjected to frequency conversion by a frequency converter circuit which includes an exclusive OR element, a running average generator consisting of a shift register and an adder, and a comparator.  In response to the output of the frequency converter, a phase comparator outputs a relative phase signal representing the phase shift of the received signal after frequency conversion relative to the phase reference signal.  The phase comparator includes:  an exclusive OR element; an absolute phase shift measurement means consisting of an adder and D flip-flop arrays; and a D flip-flop serving as a phase shift polarity decision means.          Alternatively, the phase detection circuit for generating the relative phase signal may include:  a half-period detection means consisting of a delay element and an exclusive OR element; a phase reference signal generation means consisting of a modulo 2N counter, and a phase shift measurement means consisting of a phase inversion corrector and a D flip-flop array.  The delay element delays the relative phase signal by one symbol period and the subtractor outputs the phase difference signal representing the phase transition over each symbol period of the received signal.  The decision circuit obtains the demodulated data from the phase difference signal.

Abstract: Faults occurring in a telecommunications system (21) are monitored identifying their time of onset and reporting them to an operator through an interface (16) if they have not cleared within a predetermined interval. Transient faults, which do clear within that interval, are not reported directly, but only if such faults occur more frequently than a predetermined rate. This is determined by establishing a scan interval, and an analysis period equal to a plurality of scan intervals, monitoring the system (21) continuously for the occurrences of faults, and storing their times of occurrence in a store (8). At the end of each scan interval, the number of occurrences of the fault during the analysis period which ends at the end of the scan interval are counted by a counter (11). If the number of occurrences of the fault in the analysis period is equal to or greater than a threshold value selected by user input (16), an alarm indicator (17) is activated. This allows isolated transient faults to be disregarded, allowing the user to concentrate on recurrent intermittent faults.

Granted: 2003-10-28
Abstract: A method for infrared (IR) imaging using a panel made of integrated GaAs quantum well infrared photodetector (QWIP) and near-infrared (NIR) or visible light emitting diode (LED). The panel is a large area diode with an optical window for top illumination or without the window for backside illumination. The integrated device acts as a photon energy up-converter which converts infrared light of wavelength longer than about 1.1 µm to near infrared or visible light which falls into the silicon detector spectral range. Using this device, an IR image is up- converted and the resulting NIR or visible image is then detected by an off- the-shelf silicon charge-coupled-device (CCD) camera. The image detected on the CCD camera represents the original infrared image. A specific device embodiment for converting 9 µm IR to 870 nm NIR is given. Using this up-conversion scheme a multicolor or multispectral version is easily realized, which provides the capability of simultaneously imaging in several infrared wavelength regions. The imaging panel can also be used with other forms of photodetectors.
