Title: Protection of analog reference and bias voltage inputs
Inventor: HARRIS COLIN
IPC: H01L27/06
Filed: 1989-02-01
Granted: 1993-03-23
Abstract: ABSTRACT             A latchup and electrostatic discharge protection circuit for an analog reference or bias voltage power supply input connected between an input power providing terminal of the power supply and a power rail of a CMOS integrated circuit having a parasitic latch device.  The protection circuit comprised of three field effect transistors close-circuits a path from the power supply input to the power rail for normal power supply conditions and open-circuits the path for excessively positive and negative voltages at the power supply input, thereby safeguarding the CMOS integrated circuit from currents resulting from the excessive positive and negative voltages.

Abstract: ABSTRACT           Apparatus for breaking an optical fiber comprises fiber gripping units each comprising a rigid block having adhered there-to a strip of a resilient material, for example a synthetic felt, the blocks being relatively movable between an open position to receive an optical fiber between the resilient strips and a closed position to clamp the fiber between the strips.  A fiber holder is provided for applying a pulling force to the fiber to cause it to slide between the resilient strips in the closed position of the blocks.  Before being inserted between the strips, the fiber is formed with a V-shaped notch at which the fiber is to be broken.          The strips are so configured that as the fiber slides between the strips it is first bent about the notch, after which the direction of bending of the fiber is reversed so that fiber is broken at the notch under the pulling force applied to the fiber by the fiber holder.  The one severed end face of the fiber is then pulled away from the other by the fiber holder 9.

Abstract: Abstract of the Disclosure HIGH AVAILABILITY CACHE MEMORY   A high availability set associative cache memory for use as a buffer between a main memory and a central processing unit includes multiple sets of cache cells contained in two or more cache memory elements.  Each of the cache cells includes a data field, a tag field and a status field.  The status field includes a force bit which indicates a defective cache cell when it is set.  Output from a cache cell is suppressed when its force bit is set. The defective cache cell is effectively mapped out so that data is not stored in it.  As long as one cell in a set remains operational, the system can continue operation.  The status field also includes an update bit which indicates the update status of the respective cache cell.  Replacement selection logic examines the bit pattern in all the cache cells in a set and selects a cache cell to be replaced using a first-in first-out algorithm.  The state of the update bit is changed each time the data in the respective cache cell is replaced unless the cache cell was modified on a previous store cycle.

One of the clutch halves has substantially radially oriented projections (3) which consists of a rigid, wear-resistant material and are partly embedded in an elastically deformable carrier (2). Their projecting ends engage opposite recesses (6) in the other clutch half. Due to the elasticity of the carrier material the projections will, in response to the magnitude of the torque transmitted by the clutch, tend to deviate from their initial, radial positions and, when a predetermined torque limit value is exceeded, assume positions where the clutch starts skipping.

Granted: 2002-11-07
Abstract: One embodiment of the present invention provides a method of testing for compounds which may induce STF-1 transcription. Pancreatic islet cells which express the STF-1/lacz fusion gene are isolated and the effect of various compounds on STF-1 expression is measured by adding the compound of interest to STF-1/lacZ expressing cells. LacZ activity in control and treated cells is then quantitated by a colorimetric assay. Using this method, a large number of compounds can be screened and STF-1 inducing compounds can be identified readily. Another embodiment of the present invention provides a method of using the STF-1 promoter to mark insulin producing pancreatic islet cells in vivo. In this regard, the green fluorescent protein (GFP) served as an indicator. The introduction of the STF-1 green fluorescent protein transgene into pigs allows for the efficient and rapid recovery of insulin producing cells from the pancreas.
