Title: Printed circuit board cooling system employing bellows and layer of thermal grease and method for forming the layer
Inventor: SUZUKI MASAHIRO
IPC: H01L23/473
Filed: 1988-05-16
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE          A cooling system used with a printed circuit board having at least a solid circuit component thereon, comprising a cooling header and cooling modules connected to the cooling head-er.  Each of the cooling modules engages one of the components.        The cooling module has a heat transfer plate connected to one end of a bellows which is connected to the cooling header at the other end.  A layer of thermally conductive compound such as a layer of thermal grease is interposed between the heat transfer plate and the corresponding circuit component.  The thermally conductive layer is initially pressed with a pressure higher than a critical pressure, and thereafter, the pressure is reduced to working pressure exerted on the circuit component provided by the resilient force of the bellows and the hydraulic pressure of the coolant.  The critical pressure is predetermined experimentally.          As a result, the thermal contact resistance between the heat tran-sfer plate and the circuit component is favorably reduced and stabilized.

Inventor: HANDKE HEINZ
IPC: B05B12/08
Filed: 1988-07-08
Granted: 1992-03-10
Abstract: ABSTRACT            Process and Plant for Series Coating of Parts Coating defects may arise due to the tolerances with which the automobile bodies are transported by the conveying system into the spray box during the series coating, e.g., of motor vehicle bodies using lacquering robots.  To solve this problem, the distance between at least one reference point and the automobile body is measured during an original coating operation and stored as a standard measured value.  The corresponding distance is then measured each time during the subsequent series operation and compared to the standard measured value.  The processing program can be corrected accordingly as a function of the deviations determined.

Granted: 1992-01-28
Abstract: Abstract of the Disclosure A low dropout voltage regulator with a switched redundant input, which has low dropout voltage before, during, and after a switch to the redundant input.  In a preferred embodiment, the inventive voltage regulator includes two transistors that are controlled by the output of an error amplifier, and redundant input voltage sources.

The other transistor conducts when the second input voltage exceeds the first input voltage.  When both input voltages are have substantially equal magnitude, both transistors conduct.          In a preferred embodiment, one input voltage is supplied by a battery, and the other is supplied by a storage capacitor charged by the battery.  When the battery fails, the storage capacitor will discharge, thus serving as a time-varying redundant voltage source in the event of battery failure.

Abstract: An optical fiber (F) and a laser (L) are fixed on the top faces of two bases (EF, EL) which also have two facing vertical faces. A spring (4) presses these two faces against each other so as to create thrust friction. The thrust force is initially moderate in order to enable the relative vertical and transverse positions (GV, GT) of the two bases to be adjusted smoothly, after which the force is increased progressively in order to prevent relative displacement taking place while the two bases are being welded together by means of a YAG laser. The invention is particularly applicable to making optical transmission heads usable in optical fiber telecommuncations systems.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of monitoring an output and adjusting the action affecting the output continuously for an electronic automatic  transmission  system  wherein  a  controller  is programmed to "learn" from the results of its operation.          The transmission control system includes a microcomputer-based controller which receives input signals indicative of engine speed, turbine speed, output speed (vehicle speed), throttle angle position, brake application, predetermined hydraulic pressure, the driver selected gear or operating condition,  engine  coolant  temperature,  and/or  ambient temperature.  This controller generates command or control signals  for  causing  the  actuation  of  a  plurality  of solenoid-actuated valves which regulate the application and release of pressure to and from the frictional units of the transmission system.  The controller executes predetermined shift schedules stored in the memory of the controller through appropriate command signals to the solenoid-actuated valves and the feedback which is provided by various input signals.

Abstract: SYSTEM AND METHOD FOR DETECTING INTERNAL STRUCTURES CONTAINED WITHIN THE INTERIOR REGION OF A SOLID OBJECT          Abstract of the Disclosure In a method and apparatus for detecting and displaying arbitrary interior surfaces of a three-dimensional body from a regular array of values of at least one physical property in the interior of the body, the physical property measurements are made with systems such as computerized tomographic x-ray imaging, or magnetic resonance imaging.  A recursive algorithm starts with a seed voxels in the surface of interest and continues to all adjacent voxels having a common face which is penetrated by the surface of interest. The common surface penetrations are derived from a look-up table which lists the adjacent voxels having a common penetrated face for each voxel index.  The voxel index, in turn, is the string of binary digits representing the voxel vertices whose vertex values exceed the surface value of the surface of interest.  The resulting list of voxels can be processed by conventional processors to display the surface of interest with greatly reduced interference from nearby, closely intermingled surfaces with the same or similar surface values.
