Title: MEMS device with reduced stiction
Inventor: UEYANAGI KATSUMICHI
IPC: H01L21/311
Filed: 2002-02-13
Abstract: The bottom surface 112, 133 of a micromachined strain gauge sensor is roughened by doping with a high impurity concentration using ion implantation. The roughened surface is initially formed on a bottom surface of a silicon sensor substrate 101 and bonded to a supporting silicon substrate 103 via a sacrificial oxide layer 102. The sensor substrate is then thinned from the top side by grinding and the sacrificial oxide is removed by preferential etching using HF. The uneven surface of the lower sensor surface reduces the contact area between the sensor and the support substrate, thereby reducing the tendency of the sensor and the support sticking together which is caused by the surface tension of a rinsing liquid 300 used subsequent to the sacrificial oxide etch.

Title: Collet-cone slip system for releasably securing well tools
Inventor: DOANE JAMES C
IPC: E21B33/129
Filed: 2002-02-28
Abstract: A selectively released well tool anchor has a tubular wicker shoe cage 72 and a tubular setting sleeve 74 in sliding assembly over a tubular mandrel (12, figure 1B). The wicker shoe cage 72 confines a plurality of independent wicker shoes 114. The tubular setting sleeve 74 has a conical slip face 102 that is loosely meshed with the shoe cage 72 by a plurality of collet fingers 77 extended from the conical slip face 102 into meshed engagement with detents 94 in the shoe cage 72. The collet fingers 77 are secured within the detents 94 for well run-in by calibrated shear fasteners 75. Slip faces 112 on the several wicker shoes 114 are aligned with the conical slip face 102 to effect a radial displacement of the wicker shoes 114 by an axial translation of the setting sleeve 74 relative to the shoe cage 72. However, no relative axial translation may occur until sufficient axial compressive force between the shoe cage 72 and setting sleeve 74 is imposed to shear the calibrated fasteners 75. For selective release from the well bore, the setting sleeve 74 has a body lock ring (58, figure 13) assembled to the internal bore of the setting sleeve 74. The lock ring (58) has internal buttress threads (137, figure 13) that mesh with external buttress threads (19, figure 1B) on the mandrel (12) at a selected position along the mandrel length. Displacement of the mandrel (12) to engage the mandrel threads (19) with the lock ring threads (137) draws the conical slip face 102 from the wicker shoe slip face thereby releasing the wickers 114 from a penetrated engagement with the well wall. Also claimed is a method of releasably anchoring a well tool to a well wall including the step of axially compressing two tubular members over tubular mandrel to radially extend wicker shoes.

Title: Chain wear monitoring system
Inventor: LODGE CHRISTOPHER JAMES
IPC: B65G43/02
Filed: 2003-04-05
Abstract: A method automatically monitors the wear of a chain when in operation in a chain drive assembly. First and second markers M1,M2, are applied to the chain at a predetermined distance d apart. A first sensor S1 is disposed adjacent to the chain to coincide with the position of the first marker. A second sensor S2 is disposed adjacent to the chain to coincide with the position of the second marker. The sensors generate signals in response to the detection of the markers. When the chain drive is operated the first and second sensors are initially triggered substantially simultaneously by said first and second markers respectively. After the chain extends through wear elongation is identified by detecting a time delay between the triggering of the first and second sensors by the respective markers. One of the sensors is then moved to a position where substantially simultaneous triggering of the sensors by the markers can be resumed. The distance the sensor has to be moved is measured to determine the elongation length of the chain. An apparatus for monitoring chain wear is also disclosed.

Title: A monolithic microwave SPDT FET switch with resistances to counteract the effect of signals coupled to the control circuit
Inventor: FUJINO HIROAKI
IPC: H03K17/693
Filed: 2004-06-10
Abstract: A monolithic SPDT switch comprises four FETs 1a-1d in a conventional series-shunt configuration controlled by command signals applied at pads 2a and 2b. The pads 2a and 2b are connected to the FETs by relatively long tracks (figure 1A) which may be subject to the coupling of high-frequency signals from the switched signal ports. To reduce the leakage of coupled high-frequency signals off-chip from the pads 2a,2b, resistors 12a-12d are placed in series with the tracks near to the pads. Similarly, series resistors 11a-11d placed near to the FET gates reduce the effect of coupled signals on the FET gates, thereby reducing ripple in the insertion loss characteristic (figure 2). The resistors 12a-12d may be placed within 200 microns of the control pads. The resistance of the resistors 11 and 12 may be set by adjusting the width of the tracks or by using different materials for the wiring patterns. Alternatively, lumped resistance elements may be used.

Title: Data replication based upon a non-destructive data model
Inventor: NGO THOMAS J
IPC: G06F17/30
Filed: 2003-01-31
Abstract: In a data-replication system, multi-way synchronization of copies of the data at different devices is achieved by employing a non-destructive data model. In this model, each replicated data object is represented by a revision graph, and every operation that is performed on a data object, e.g. a revision of data content or deletion of the object, is represented by adding a node to a revision graph at the device where the change is made. Synchronization between multiple devices is achieved by applying a graph union operator. Since the union operator is commutative and associative, it avoids the limitations normally associated with the order in which updates occur. A synchronization enforcement mechanism restricts the situations in which the nodes of a graph can be deleted, to thereby ensure integrity of the data throughout its useful life cycle.

Patent GB-2422900-A (GB)
Title: Actuator device
Inventor: TURPIN MARK CHRISTOPHER
IPC: B32B7/02
Filed: 2005-01-21
Abstract: This invention relates to the actuation of switches and valves as a result of changes in the concentration of one liquid dispersed in another. The invention makes use of the well-documented propensity of certain cross-linked, branched or otherwise molecularly entangled polymers to swell, reversibly and without dissolution, in certain solvents. If the cross-linked polymer is exposed to a swelling solvent in combination with other solvents, which have reduced swelling properties with respect to the particular polymer, then the degree of swelling observed is markedly dependant on the concentration of the swelling solvent in the mixture. The swelling of the polymer is used to mechanically actuate switches or valves either directly or through the use of a multi-layer construct. The invention is particularly apposite to the control of methanol concentration in direct methanol fuel cell systems.
