Patent EP-0393373-A2 (EP)
Inventor: WERNER KARL JOSEF DIPL-ING
IPC: H04B10/61
Filed: 1990-03-21
Abstract: The invention relates to an optical heterodyne receiver (1000) with simultaneous evaluation of the signal frequency and mirror frequency, the local oscillator power being utilised to an optimum degree. In an optical mixing stage (800), a local oscillator signal (2) with circular polarisation and with a reception signal (1) with linear polarisation are divided up between two optical mixing signal paths (211, 212, 221) forming in each case identical signal components. In a mixing signal path there is a half-wave plate. The further processing to form intermediate frequency output signals (81, 82) takes place in a polarisation beam splitter (130) and an electronic intermediate frequency stage (900). Deviation from the envisaged linear polarisation of the reception signal (1) causes a calculable degradation of the mirror frequency suppression. <IMAGE>

Abstract: This headlamp for a motor vehicle comprises a lens that has a front surface (31) that slopes backwardly from bottom to top of the lens. In localized regions of the lens, there are spread flutes, each comprising alter­nating ridges (28) and grooves (29) on the back surface of the lens. The individual ridges extend in a direction be­tween the top and bottom of the lens and are character­ized by having the form of a segment of an inverted, base-up cone. The individual grooves (29) extend in a direc­tion between the top and bottom of the lens and are characterized by having the form of a segment of an upright, base-down cone. The coniform configuration of the individual ridges (28) and grooves (29) serves to lift the edges of the light beam passing therethrough and thereby compensate for the tendency of the beam to droop at its edges as a result of the backward slope of the front surface (31) of the lens.

Abstract: The invention relates to an underroofing having heat insulating slabs laid on roof laths. According to the invention, a slab central part (8) has a greater thickness than the edges, facing the slab centre, of ridge- and eaves-side, wedge-shaped slab parts (2, 3), the ridge-side slab part (2) merging into the slab central part (8) by way of an upper-side step (20) and the eaves-side slab part (3) merging into it by way of an underside step (6) supported on the ridge-side side face (11) of the roof lath (12) concerned. The lateral slab edges form a side groove (25) which begins at a distance from the ridge-side slab edge (9) in the ridge-side slab part (2), extends over the slab central part (8) and ends at a distance from the eaves-side slab edge (19) in the eaves-side slab part (3), and which in the process rises at an acute angle to the plane (10) of the roof lath. Thus, a heat insulating slab design which is of low susceptibility to damage and provides a sealed underroofing is possible. <IMAGE>

Abstract: A coded transmission system wherein each bit of transmitted data having a logical value is coded depending on a coded result of a preceding bit, containing a sender-side apparatus, a transmission line, and a receiver-side apparatus. The transmission line connects the sender-side apparatus with the receiver-­side apparatus. In the sender-side apparatus, a resetting bit and a message are generated; a code of a bit which is last transmitted and is necessary to code a bit which is to be transmitted next, is memorized in a first preceding code memorizing circuit (5), where the content of said first preceding code memorizing circuit (7) is reset to an initial code responding to the resetting bit. A coding circuit (1, 2, 3, 4) receives the resetting bit and the message, coding each bit of the message in accordance with a predetermined coding rule and the content of the first preceding code memorizing circuit, and coding the resetting bit to a predetermined resetting code which is different from the codes used in the coding of the message. In the receiver-side apparatus, a code of a bit which is last received and is necessary to decode a code of a bit which is received next, is memorized in a second preceding code memorizing circuit (17). A resetting circuit resets a content of the second preceding code memorizing circuit (17) to a predetermined initial code when receiving the resetting code. A decoding circuit (11, 12, 13, 14) decodes received codes corresponding to the message in accordance with the above predetermined rule and the content of the second preceding code memorizing circuit (17).

Abstract: An oxygen-fuel burner (10) is disclosed which has a wide range of operation, allowing a turn-down ratio of 5 to 1. In addition, the burner construction (10), which is not liquid cooled, maintains an acceptable burner tip temperature by having a tip (22) which extends outwardly beyond the nose portion (14) of the burner such that the oxygen flows columnarly therealong and functions to remove heat from the tip (22). A delayed combustion is obtained by the gas discharge tip (22) being axially spaced apart from the oxygen discharge orifice (16). The burner produces sufficient heat to permit the melting of batch materials to produce molten glass without the use of regenerators or recuperators.

Abstract: A control method for preventing the incorrect resetting of a common resource in a multicomputer system comprising a plurality of clusters each having a processor and a common memory which each cluster can access, comprises steps of storing in a common memory an IPL (initial Program Load) generation ID (Identifier) which is unique to an IPL number of each cluster, setting an acquisition ID and the IPL generation ID in the common resource, when the right to use the common resource in the common memory is acquired, and comparing the IPL generation ID when the faulty cluster stops, with the IPL generation ID set in the common resource, and only when the two IPL generation IDs are equal, resetting the right to use the common resource, when the right to use the common resource which the stopped faulty cluster acquires is reset. Thus, when resetting a common resource when a cluster included in a system stops operating due to a fault, incorrect resetting can be prevented so that the cluster does not reset the right to use the common resource acquired after restart of the IPL.

Abstract: A vehicle dynamic characteristic control apparatus for use with an automotive vehicle having a pair of front wheels and a pair of rear wheels. The apparatus comprises a first unit for controlling braking forces to be applied to left and right wheels of at least one of the wheel pairs, a second unit for controlling a steering angle of one of the wheel pairs, and a third unit for controlling the first and second units. In the absence of vehicle braking, the third unit calculates a first target value for a first parameter related to a first motion of the vehicle based upon vehicle operating conditions and controls the second unit to bring the first parameter to the first target value. The third unit calculates a value of a second parameter related to a second motion of the vehicle provided when the first parameter is controlled to the first target value in the absence of vehicle braking. In the presence of vehicle braking, the third unit calculates changes in cornering powers of the respective wheel pairs and modifies the first target value based upon the calculated cornering power changes. The third unit controls the second unit to bring the first parameter to the modified first target value and controls the first unit to bring the second parameter to the calculated value.

Abstract: A method and apparatus for rapidly moving a reading beam of light radially relative to a rotating record disc, to impinge on a selected target track on the disc and recover information recorded on it. The apparatus first radially translates an optical system that directs the beam onto the disc at a relatively high speed until it is within a prescribed radial distance of the target track. Thereafter, an element of the optical system is controllably deflected such that the beam moves incrementally across a prescribed plurality of tracks during each disc revolution, until reaching the target track. The information recorded on each track includes a unique address signal, and movement of the beam relative to the disc is controlled according to the difference between the respective addresses of the track currently being scanned and the target track. If the apparatus fails to properly recover a track address signal, it estimates the address of the track currently being scanned, and updates its control of the beam's radial movement based on that estimate.
