Title: Multiple pass error correction process and apparatus for product codes.
Inventor: ZOOK CHRISTOPHER P
IPC: H03M13/00
Filed: 1988-05-27
Abstract: An error correction system (20) comprises a multi-pass controller (32) which operates through a controller/decoder interface (34) to supervise the execution of decoding passes by a decoder (30). The multi-pass controller (32) employs a correction procedure comprising a plurality of hierarchial strategies S(1), S(2), . . . S(N) for transitioning the procedure through a plurality of predetermined states. Upon completion of a decoding pass, a pass evaluator (70) evaluates the results of the decoding pass and uses the evaluation for establishing values for further operation. Further passes are executed in accordance with further states determined by the multi-pass controller (32), the further states having particular parameters associated therewith including a strategy selection.

Patent EP-0351758-A1 (EP)
Inventor: WALLING PETER THORBURN
IPC: A61F2/958
Filed: 1989-07-17
Abstract: To inflate the balloon element on the distal end of a pulmonary artery catheter an improved gas syringe is pro­vided which is both volume and pressure-limited so that the syringe is capable of discharging into the catheter no more than the maximum design gas inlet volume thereof while at the same reducing the maximum attainable pressure within the catheter to a predeterminable level substantially below that reached when a conventional volume-limited syringe of the same gas discharge capacity is used. The syringe volume delivery limitation is achieved by forming rearwardly disposed plunger stop members, or a suitable vent opening, in a sidewall portion of the syringe body. The pressure limitation is obtained by forming a pressure absorption zone which defines a substantially inextensible enlargement of the gas-receiving interior of the catheter. In an alternate embodiment of the syringe, an orifice plate having a small orifice opening therein is secured across the syringe outlet to limit the balloon inflation rate during an initial por­tion of the operation of the syringe.
Patent EP-0369115-A1 (EP)
Inventor: GOTH GARY FRANKLIN
IPC: H01L23/473
Filed: 1989-08-01
Abstract: An otherwise conventional multi-chip circuit module called a thermal conduction module (TCM) is provided with "barrel shaped" pistons (22) that give improved cooling for chips (15) that may be tilted with respect to their pistons. The piston has a cylindrical mid-section (32) and tapered end sections (33, 34). The barrel shape permits the piston to tilt with the chip even though the mid-section has the desirable close fit of conventional convex face pistons. The length of the mid-section is selected to permit the piston to tilt to the angle of the taper of the ends. Because the piston can tilt with the chip, the end (29) that contacts the chip is flat for good heat transfer. The result is improved heat transfer by a lower combined thermal resistance of the gap between piston and chip and the gap between piston and hat versus conventional pistons.

Title: Torque-absorbing support for a detachable gear box
Inventor: HILLE FRIEDRICH DIPL-ING
IPC: F16H57/02
Filed: 1989-11-28
Abstract: The torque-absorbing support consists essentially of four identical rings (10), of rectangular cross-section, in a coaxial arrangement. The two inner rings (10b) are rigidly connected to each other by a hollow shaft (16). The two outer rings (10a) are screwed tightly, one to the fixed machine housing (1a) and on the other hand to the gearbox housing (2a). In each case one inner and one outer ring are elastically connected in a rotationally fixed manner by an intermediate bearing consisting of spring straps (13), arranged in the form of a polygon, which are in each case screwed, parallel to the axis, with one end to one ring (10a) and with the other end to the other ring (10b). This results in the reaction torque of the machine housing being absorbed without lateral forces. <IMAGE>

Abstract: A circuit for producing a constant voltage comprises first and second MOSFETs, and first and second bias voltage producing devices. The first and second MOSFETs to which first and second input voltages are applied, respectively, are connected in series. The first bias voltage producing device produces a potential difference, which is equal to a threshold voltage of the first MOSFET, to be applied across drain and gate of the first MOSFET, and the second bias voltage producing device produces a potential difference, which is equal to a threshold voltage of the second MOSFET, to be applied across drain and gate of the second MOSFET, so that a wide range of an output voltage is produced at a connecting point of the first and second MOSFETs. Even more, the output voltage is stabilized in level, even if the threshold voltages fluctuate in a semiconductor device fabricating process.
Patent EP-0340999-A1 (EP)
Inventor: GAENSSLE HEINZ
IPC: B23P19/06
Filed: 1989-04-28
Abstract: When tensioning a gasketed joint, the drive system applies rotational force to a threaded fastener while the monitor and control unit continuously compares a torque-related variable to a shutoff point. When the shutoff point is reached the control system reduces the drive system power, preferably to zero. After a preselected time pause the drive system is re-energized and applies another torque application until the torque-related variable again reaches the shutoff point. When the gasket is adequately compressed so that further torque applications cause insignificant increases in gasket compression, the tensioning operation is terminated. Feedback is provided by tension-related variables such as incremental angle of turn and/or incremental elapse time of the torque application to determine when the tensioning cycle is complete.
