Abstract: An integrated image recorder (100) receives an first pictorial image data from an input scanner (300) and stores the same in an image disk (150). The pixels of the picture are skipped at a predetermined rate to obtain a second pictorial image data having a low resolution. The second pictorial image data is transmitted to a front end processor (201, 202) and employed in editional designing of a page as an integrated image. The integrated image is represented in a page description language and is delivered to the integrated image recorder. The integrated image recorder is operable to read out the first pictorial image data from the image disk and to convert the integrated image into a bit map using the first pictorial image. The integrated image is then delivered to an output scanner (190) and is recorded on a recording medium.

Abstract: Both an apparatus (1) and a method for monitoring the pressure within a cask (5) containing radioactive materials. The apparatus (1) comprises a differential pressure sensor (55) sealingly connected to a bore (41) that penetrates through the wall (7) of the cask (5) for directly monitoring the pressure of the helium gas contained within the cask (5) and for providing a first barrier between the helium gas and the ambient atmosphere.

Abstract: An adapter (22), having a dielectric substrate (30) upon which are mounted an array of uniformly-spaced, coplanar conductive strips (32) and impedance standards (40,46,48,50) having similarly spaced coplanar leads (44), facilitates planar transmission line probe measurements of the high speed-electrical characteristics of a package or other interconnect structure (10) for a high-speed integrated circuit. The conductive strips (32) of the adapter (22) are connected to the terminals (18) of the package (10) so as to simulate the integrated circuit connection, that is, with substantially identical length and spacing of bond wires (24). The planar probe (26), by contacing the conductive strips (32) of the adapter, is able to measure the electrical characteristics of the package (10) including the bond wires (24), thereby providing realistic measurements of the integrated circuit's environment. The impedance standards (40,46,48,50) on the adapter are specially designed to enable the effects of the adapter to be removed from the measurements by calibration.

Abstract: A method for monitoring a brake system with anti-blocking control and/or drive slip control is presented. For this purpose, it is equipped with an electronic controller (75). For the purpose of monitoring, a volume and/or pressure pulsation image is picked up by means of a sensor (89) and passed on to the electronic controller (75) in the form of electrical signals. In the electronic controller (75), a volume and/or pressure pulsation image which represents correct functioning of the brake system is electronically stored. The current volume and/or pressure pulsation images picked up by means of the sensor (89) are compared with the standard image stored in the controller (75). In the event of one or more current images deviating from the standard image, an interference signal is produced by the controller (75). The method supplies a comprehensive, safe, cost-effective monitoring, in particular of pump delivery.

Abstract: In order to reduce the number of update operations for determining LPC (viz., reflection) data from an incoming sampled data, a plurality of matrices representative of autocorrelation functions are set in memory. Subsequently, data representative of the upper triangular portions of the matrices (virtual upper triangular matrices) are extracted from the memory and arranged into an array. This array is then updated using a j-th reflection coefficient, after which the value of j is incremented and the updating is repeated until a predetermined number of updating is completed.

Abstract: There is provided an image sensor which can reduce loss in light emitted from a light emitting section toward an object to be sensed and also variability in the distribution of light and which can be produced with a small-sized structure with a reduced number of parts and with a decreased manufacturing cost. An optical path from the light emitting section (13) to a transparent covering (12) on which the object is to be placed is surrounded by a light reflecting portion comprising light reflecting surfaces (18a, 19a, 20). Light from the light emitting section (13) can be irradiated onto the transparent covering (12) without a reduction in the amount of light while being repeatedly reflected by the light reflecting portion. The light reflected by the object is condensed by a condensing lens (16), the condensed light being then received by a light receiving section (14) mounted on the same base plate (15) as in the light emitting section (13). At the light receiving section (14), the light is converted into an electrical signal.

Abstract: Such devices are preferably used for testing cables and connectors used in automotive construction, for interlocking faults. To avoid confusion during the assembly, the various connectors are designed to have different shapes and can only be plugged into a correspondingly matching receiving part in each case. This means that a separate device must be produced virtually for every connector, which, due to a large number of other components needed, are relatively expensive to produce so that a considerable expenditure is incurred due to the large number of different connectors in existence. The invention is to provide for a less expensive production of the device and for simpler exchange. For this purpose, it is provided that the receiving part (2) is arranged to be removable and locked in position in a housing (1). Due to the invention, an exchange of the receiving part only is thus required whilst the remaining components belonging to the device can be used for all plug-in-type receiving parts. This naturally results in considerable cost savings.

Abstract: By implanting contacts to a p-layer (17) buried beneath the quantum wells (16), a SEED can be fabricated which is substantially planar, free of mesa sidewalls, and has enhanced performance characteristics as compared with the conventional mesa SEED. The SEED is substantially planar in that it contains no semiconductor surface in the region of the photodiodes (11,12) within about a micrometer thereof) that rises more than about 3000 angstroms from the uppermost continuous semiconductor surface. Indeed, with the disclosed structure the highest such region can be only a few hundred microns above the continuous surface. The SEED is free of sidewalls in that no outer surface of the semiconductor material contains any surface region of the active portion of the quantum well structure. Moreover the resulting SEED has a topography well suited for integration with other electronic components.

Accordingly, the number of parts can be reduced, and a space for iristalling a mechanism for driving the reel bed gears can be made small.

Abstract: The present invention refers to improvement of a frame structure and, especially, to a suspension structure for a unit swing-type engine (15). The inventive suspension structure includes chassis side brackets (20), engine side brackets (18), and links (19) connecting said chassis side brackets to said engine side brackets. The suspension structure is improved in that engine side brackets (18) are formed separately from, and connectable to, the unit swing-type engine (15). Thus, the same engine can be used for different models of motorcycles. Furthermore, the number of assembly steps is reduced. In a further embodiment of the invention, one end of the down tube is connected to the lower end of a head pipe by way of a joint extending backward from the head pipe. As a result, a large stowing space is provided behind the head pipe.
