Patent EP-0345702-A2 (EP)
Inventor: QUINCKE JORG DIPL-ING
IPC: H01L27/08
Filed: 1989-06-05
Abstract: A knowledge of the latch-up extension in integrated CMOS circuits is of decisive importance for the microelectronic device development engineer in order to be able to reduce latch-up sensitivity in such circuits by a design change or technological measures. Since the known methods of investigating the latch-up extension have only a relatively low time resolution, it is proposed to trigger the latch-up periodically, to sample the intensity of the infrared radiation originating from the circuit consecutively at a plurality of measuring points covering the circuit in the form of a grid at a specified time  tau  after the occurrence of the trigger signal initiating the latch-up and to record a measured value representing the intensity I( tau ) as a function of the position in each case.

Abstract: An optical communication system (Figs. 1-4, 6-7) which includes an optical transmitter (Fig. 1) for transmitting an optical signal through a single-mode optical fiber (22, 88) to an optical receiver (Figs. 3, 9, 10). The optical transmitter includes an optical source for generating a light beam. The optical source is preferably a high speed laser diode (20, 86) emitting in a spectral range of 1.3 - 1.6 micrometers. The light beam is intensity modulated with a composite modulation signal comprising one or more modulated microwave subcarriers and a baseband digital signal. The microwave subcarriers are typically in the frequency range between 2 and 20 gigahertz, and the baseband digital signal is typically a time-multiplexed signal carrying multiple voice and data channels. By simultaneously transmitting a baseband digital signal and multiple microwave subcarriers on a single optical fiber, the information-carrying capacity of the optical communication system is increased.

Abstract: Many housings for electronic devices require to be carefully sealed, as well as incorporate heat sinks for the electronic devices. Careful sealing has required expensive machined housing joints and, because electronic devices may be misaligned to the substrate, rounded heat sinks have been used, giving restricted contact areas and hence limited cooling. The invention employs a thermally conducting flexible membrane capable of being urged into thermal contact with the electronic device for example an evacuation of the housing thereby permitting a simple hermetic seal as well as contact with the electronic device over a large area.

Abstract: A height adjusting device for adjusting the height of a pick-up (4), comprises a support mechanism (59,60) for supporting the pick-up (4) on the carriage (56) in a manner that a position of the pick-up (4) along the axis of rotation of the turntable of the optical disc player is adjustable and an adjusting device (53-55) For driving the support mechanism (59,60) to adjust the position of the pick-up (4).

Abstract: A binary operator comprises a plurality of carry select adder (CSA) circuits (101 a) each including a cumulative carry propagate signal generating means (106) and a cumulative carry generate signal generating means (107) and or a plurality of block look ahead carry generator (BLACG) circuits (105a) each including a cumulative block carry propagate signal and cumulative block carry generate signal generating means (116) and a real carry signal generating means (117). The CSA circuit (101a) does not simultaneously generate two presumed sum signals and select and output one of the presumed sum signals, but directly performs operations on the three signals of a carry propagate signal (P ; ), a cumulative carry propagate signal (BP i-1 *) and a cumulative carry generate signal (BG i-1 *) necessary for generating the presumed sum signal pair and the real carry signal (C M-1 ) to calculate the real sum signal (F i ). The BLACG circuit (105a) does not simultaneously generate two presumed carry signals and select and output one of the presumed carry signals, but uses a cumulative block carry propagate signal (CP M-1 *), a cumulative block carry generate signal (CG M-1 *) and a carry signal (C M '- m ') to directly generate the real carry signal (C M-1 ). 
     The number of circuit elements in such a binary operator is thereby greatly reduced without sacrificing high speed of computation since two presumed sum or carry signals are never generated in parallel.

Abstract: The described holding device on medical forceps, for gripping tissue parts or foreign parts during a medical operation, consists of two elongate spring elements (1,2) whose opposite ends are secured in closed telescope tube ends (3, 4). The telescope tubes (3, 4) are connected in an articulated manner to handgrips (6, 7) of forceps. By pressing the partially elastically resilient handgrips (6, 7) together, the spring elements (1, 2) are brought into hook-type engagement by being displaced relative to one another by means of meeting surfaces (10, 11), as a result of which the tissue or the like gripped by the forceps is automatically held securely after the manual pressure on the handgrips (6, 7) has been released. By pressing the handgrips (6, 7) still further together, the hook engagement is released, so that the handgrips and the jaws of the forceps open, by means of the spring-mounting of the handgrips (6, 7), and release the gripped tissue or the like.

Abstract: A method is described for allowing data to be transferred in parallel over several input/output channels simultaneously. When a file is opened within an application program, a system library routine tasked with allocating input/output channels checks to see if multiple channels have been defined by control commands separate from the application. If the multiple channels have been so defined, the driver will open multiple channels for data transfer in a manner independent of the application. Existing applications can use this technique to perform striped input/output without requiring modification.
