Abstract: PURPOSE:To obtain the container in a low price and rich in massproductivity by a method wherein a light-penetrated window covered with a sapphire plate is formed in a cap of an Fe-Ni-Co alloy of Fe-Ni alloy. CONSTITUTION:The Fe-Ni-Co alloy kovar is used for the cap member with the window, acid-pickled, heated in H2 and then covered with a film oxide. Then, a sapphire adhered part is coated with covar glass and heated to form a glass layer 3 of temporary sintering. The sapphire plate is cleansed and activated on the surface in prior and applied a heat treatment in an oxidized atmosphere to get to fit well to the glass. The window 2 is fixedly attached to the cap 1 when covered with the sapphire plate 4 on which a weight 5 is mounted and heated in N2. The cap is welded into a stem on which a photosemiconductor element is mounted and sealed in airlight. In this construction, since the covar is used, the sapphire plate can be fixed in O2 or N2 atmosphere, being bearable against thermal shocks at +200- -55 deg.C and in addition, being low in the cost price also because Ti or the like is not used.

Abstract: A process for treating effluent wherein an oxidising agent In the effluent is decomposed on contact with a catalyst bed. The oxidising agent can be a pollutant present in the effluent, for example hypochlorite in the effluent from chlorine-producing brine electrolysis cells or from the scrubbing of chlorine gas In an alternative the effluent may contain oxidisable pollutants and the oxidising agent is purposefully added thereto.

IPC: G06F9/38
Filed: 1984-09-28
Abstract: The various functional units which comprise a central pro- cessing unit of a computer are organized so as to enable a main arithmetic logic unit and special function units including an auxilliary arithmetic logic unit to access data registers, literal constants, and data from a memory cache. A general purpose bus closely couples the functional units to the main data paths and allows the CPU sequencer to branch on numerous conditions which may be indicated via test lines. Parity from the functional units is sent a clock cycle later than results in order that the parity path does not affect machine cycle time. The architecture allows unused microcode options to be used to check for correct CPU operation by halting CPU operation on a miscompare of two buses.

Abstract: In order to identify the state "no light at the signal input of the receiving device", measured values are stored at predetermined time intervals which in each case provide a measure of the electric signal level. If digital signals are missing, the contents of the memory (13) are investigated, if necessary in conjunction with a further measured value, in connection with the change in the level. In the event of a comparatively significant change in level, "no light at the input of the receiving device" is signalled. The method and the circuit arrangement can be used advantageously in the monitoring of comparatively long optical transmission paths.

Abstract: The building element includes a first sound-absorbing and heat- insulating layer (21) and a second sound-absorbing, shape-retaining base layer (23). The first layer preferably comprises a thermoformed fibre mat or an at least partially open-celled foam and the second layer comprises a rigid, thermoformed plastic material, for example a plastics material reinforced with glass fibres. On the outside of the first layer, a porous or microporous decorative layer (22) may be applied and on the outside of the base layer a thermoformed carpet (24) may be applied. A heat-sealable adhesive layer (27) may be laid between the two layers, increasing the bond between them. By virtue of the shape-retaining base layer, the building element can be used as a sound barrier without any supporting frame or as a sound-damping body panel without any supporting surface, which allows the weight of the overall construction to be reduced and installation to be made easier and cheaper. <IMAGE>

Abstract: When a driver voluntarily operates the steering during an automatic steering control operation, the automatic steering control operation is discontinued and a normal power steering control operation is resumed. The automatic steering control operation is not quickly changed to power steering control operation, but rather is gradually changed to the power steering control operation, to prevent a sudden change in the steering reaction which the driver receives from the steering wheel and, hence, to decrease the feeling of incompatibility. While the control amount of a steering actuator changes accompanying the change of the operation from the mode of automatic steering control operation to the mode of power steering control operation, the control amount is linearly changed from a value of the automatic steering control operation to a value of the power steering control operation over a predetermined period of time.   <IMAGE>

Abstract: An electrophotographic apparatus which represents halftone through use of halftone spots formed of a plurality of dots, to thereby reproduce an image and which forms a virtual development region of a predetermined area at a predetermined location within dots by means of exposure of a photosensitive drum to a beam and which reproduces a real development region by causing toner to adhere to the virtual development region. In order to prevent an area narrower than a predetermined width from arising in the virtual development region, an area which is originally designated to become narrow is formed into an area of certain width, to thereby prevent formation of a much narrower real development region, which would otherwise be caused by an excessively low surface potential of the narrow area. The area of halftone spots is partially increased in the virtual development region at a single gray-scale level. In the present invention, with consideration to the phenomenon that a narrow development region becomes much narrower after printing, a virtual development region corresponding to a narrow development region in halftone spots is set to be greater than a theoretical width. Accordingly, in the virtual development region, halftone spots having a narrow development region become larger in area than halftone spots lacking a narrow development region. As a result, variations arise in the area of halftone spots at a single gray-scale level. In contrast with the case of halftone spots of the virtual development region, variation in the area of halftone spots of the actual development region is prevented. <IMAGE>

Abstract: A computer graphics system generates pixel values for pixels in an image of objects in a scene, using strictly-deterministic low-discrepancy sequences, illustratively Halton sequences, as sample points for evaluating integrals which are used to simulate a number of computer graphic techniques, including: (1) soft shadows generated for scenes illuminated by a light source having a finite extent, such as a disk, as opposed to a point light source; (2) simulation of depth of field; (3) motion blur; (4) jittering. The computer graphics system uses the low-discrepancy sequence: (1) in connection with soft shadows, to generate sample points over the extent of the light source illuminating the scene; (2) in connection with simulation of depth of field, to generate sample points over the area of the lens between the scene and the image; (3) in connection with motion blur, to generate sample points over a time interval over which motion blur is to be simulated for moving objects in the scene; and (4) in connection with jittering, to generate jittered sample points over an image or a plurality of contiguous pixels. Unlike the random numbers used in connection with the Monte Carlo technique, the low discrepancy sequences ensure that the sample points are evenly distributed over a respective region or time interval, thereby reducing error in the image which can result from clumping of such sample points which can occur in the Monte Carlo technique. In particular, the invention facilitates the generation of images of improved quality when using the same number of sample points at the same computational cost as in the Monte Carlo technique.
