Abstract: The automotive lamp assembly according to the present invention comprises a divergent-type concave mirror formed by a central reflecting area in which the optical axis lies and peripheral reflecting areas continuously extending rightward and leftward from the central reflecting area, and a lamp bulb disposed on the optical axis of the concave mirror. Either of the central and peripheral reflecting areas is formed as a first reflecting curved surface composed of a part of a paraboloid of revolution to reflect the incident rays of light from the lamp bulb in directions parallel to the optical axis, and the other is formed as a second reflecting curved surface to reflect horizontally the rays of light from the lamp bulb in directions divergent from the optical axis depending upon the distance from the vertical plane in which the optical axis lies and also reflect vertically the rays of light in directions parallel to each other and to the horizontal plane in which the optical axis lies. The first reflecting curved surface defines a central hot zone in the light distribution pattern, and the second reflecting curved surface defines middle and low illuminance zones extending rightward and leftward from the center of the light distribution pattern. Therefore, the rays of light from the lamp bulb can be effectively utilized and a desired light distribution pattern can be freely obtained.

Abstract: A process for the production of images in a printing cylinder in a rotary offset machine is specified, in which parts of the surface of the printing cylinder are changed in respect of their ink/water affinity by means of a substance coating which is adequate for the image and influences the ink guiding. In contrast to a known process, in which the substance transfer likewise takes place by means of the thermotransfer process but directly onto the printing cylinder provided with a hard surface, the process according to the invention is characterised in that the substance coating takes place at least as an alternative on a soft surface. For this purpose, either the surface of the printing cylinder is soft or the transfer takes place in two transfer steps with interposition of a transfer cylinder with a soft surface - preferably of the blanket cylinder. The process guarantees an even transfer of the substance even in the case of relatively wide production tolerances since deviations in the transfer line relating to distance and pressing force are compensated. <IMAGE>

Abstract: A system for controlling automatic continuously variable transmission equipped with a motor vehicle utilizing fuzzy logic. In the system, fuzzy production rules have been prepared based upon an expert driver's judgments and operation made on a vehicle with a manually shifted transmission. Various operating conditions including opening degree of a throttle valve and road speed of the vehicle are detected and from the detected value, various predictions are made such as an appropriateness of vehicle response determined from the reserve motive force with respect to a gear ratio shift intended by the driver and engine output change that would occur should the transmission be shifted to the gear ratio. These measured or estimated value are put on a common scale named universe of discourse and membership values of the rules are successively calculated. Among the rules, one rule is finally selected and according to the gear ratio indicated in the selected rule, the current gear ratio is shifted up or down or is held at the present ratio.

Abstract: A local area network for interconnecting terminals and other users and data processing systems and other service providers over a communications link. The users and providers connect to the communications link by means of interface units each of which may connect to several users or providers. The interface units communicate over the communications link by means of messages. When a user requires the use of a service, the interface unit establishes a virtual circuit between it and the interface unit connected to the service provider and a service session which allows the user and the service provider to communicate over the virtual circuit. If several users connected to the one interface unit as the first user require services provided by providers which connected to the same interface unit as the first provider, they communicate in sessions over the same virtual circuits. The session messages are accumulated into single virtual circuit messages that are acknowledged in unison by the receiving interface unit. Each virtual circuit in the users' interface units includes a timer which reset when a message is transmitted over the virtual circuit and a data waiting flag set whenever data is present to be transitted over the virtual circuit. The interface units are inhibited from transmitting over a virtual circuit unless the timer has timed out and the data waiting flag is set.

Abstract: A system and method for calibrating signals provided by individual cells in a photodetector array scanned by light originating at a low-cost variable light source and reflected from a subject to be repli­cated in digital form by processing photodetector cell signals in a manner so that individual cell signals are corrected to compensate for fluctuations in source light. The system and method is particularly applicable to a color balanced photodetector array in which individual photodetectors are arranged in sets with each set having a variable number of rows oriented in a direction transverse to the direction of scan and columns parallel to the direction of scan. The invention is practiced by exposing the first few photodetectors in each row to the full spectrum of visible light reflected from a white reference patch. During processing, as the photodetector signals are sequentially transferred, to a processor, the signals provided by the cells exposed to the white reference are compared with a fixed value to obtain a calibration factor. As the signals develop by cells in the same set but as a result of exposure to light reflected from the subject image, those signals are multiplied by the calibration factor so that the process signals are corrected for variations in source light on a real time basis.
