Abstract: In a method for operating a passive matrix-addessable ferroelectric or electret memory device comprising memory cells in the form of a ferroelectric or electret thin-film polarizable memory material exhibiting hysteresis, particularly a ferroelectric or electret polymer thin film, and a first set of parallel electrodes forming word line electrodes in the device and a second set of parallel electrodes forming bit lines in the device, the word lines being oriented orthogonally to the bit lines, such that the word lines and bit lines are in direct contact with the memory cells, which can be set to either of two polarization states or switched between these by applying a switching voltage larger than a coercive voltage of the memory material between a word line and a bit line, a voltage pulse protocol with at least one disturb generating operation cycle is applied for switching selected addressed cells to determined polarization state. The voltage pulse protocol further comprises a pre-disturb and/or post-disturb cycle before and after the disturb generating operation cycle respectively in order to minimize the effect of disturb voltages on non-addressed memory cells, when such voltages are generated thereto in the operation cycle when it is applied for either a write or read operation.

Abstract: [PROBLEMS] To obtain a simple and compact webbing winder capable of transmitting rotation from the motor side only to a winding shaft by a clutch.  [MEANS FOR SOLVING PROBLEMS] The clutch of a webbing winder has such a simple arrangement that the slider (144) at the clutch body section (114) and a lock lever (154) are moved relatively by holding the slider (144) on a case with a frictional force, and the lock lever (154) is shifted to a position engaging with a ratchet (134) or a position disengaging therefrom through the relative movement. As compared with a conventional clutch where a pawl is moved using a large and heavy inertial disc, overall structure of the clutch (100) can be reduced (can be made thinned) greatly and thereby overall structure of the webbing winder (10) can be made compact.

Abstract: Appareil rotatif adapté pour servir de compresseur, de moteur, de pompe ou de moteur à combustion interne, qui comporte deux aubes, deux manchons cylindriques creux, une gaine cylindrique creuse, des cames et des liaisons associées, des accouplements, un arbre, un embrayage et un système de freinage / blocage. Les aubes sont montées sur les surfaces incurvées des manchons, à raison d'une aube sur chaque manchon, de manière telle que les aubes sont situées radialement par rapport à la surface incurvée du manchon et à l'une des extrémités de chaque manchon si bien que la surface de l'aube fait saillie par rapport à l'extrémité du manchon. Lesdits manchons sont placés de manière telle que leurs extrémités pourvue d'une aube sont placées adjacentes, les aubes étant angulairement décalées. Lesdites aubes sont placées à l'intérieur d'une gaine et la surface interne de ladite gaine possède un profil correspondant au chemin tracé par le bord de l'aube lorsque cette dernière tourne autour de l'axe. Cette surface interne permet la rotation des aubes autour de l'axe. Les aubes divisent l'espace fermé formé à l'intérieur de la gaine en deux chambres étanches, ledit espace fermé étant étanche par rapport aux espaces externes. Les deux manchons sont couplés à l'arbre et découplés dudit arbre à l'aide d'un dispositif de couplage actionné par des cames ou d'autres dispositifs de synchronisation. Les cames ou dispositifs de synchronisation sont dépendants de la position du manchon. Les cames ou dispositifs de synchronisation actionnent des dispositifs de freinage / blocage de manière que chaque aube soit maintenue en alternance dans une position prédéterminée. Les cames ou dispositifs de synchronisation permettent aux deux aubes de tourner simultanément à un angle prédéfini, et définissent l'angle selon lequel les aubes sont séparées, et tournent simultanément ou indépendamment.
Patent CA-2567814-A1 (CA)
Inventor: WEIDANZ JON A
IPC: C07K16/32
Filed: 2005-05-27
Abstract: The present invention relates to a methodology of producing antibodies that recognize peptides associated with a tumorigenic or disease state, wherein the peptides are displayed in the context of HLA molecules. These antibodies will mimic the specificity of a T cell receptor (TCR) but will have higher binding affinity such that the molecules may be used as therapeutic, diagnostic and research reagents. The method of producing a T-cell receptor mimic of the present invention includes identifying a peptide of interest, wherein the peptide of interest is capable of being presented by an MHC molecule. Then, an immunogen comprising at least one peptide/MHC complex is formed, wherein the peptide of the peptide/MHC complex is the peptide of interest. An effective amount of the immunogen is then administered to a host for eliciting an immune response, and serum collected from the host is assayed to determine if desired antibodies that recognize a three-dimensional presentation of the peptide in the binding groove of the MHC molecule are being produced. The desired antibodies can differentiate the peptide/MHC complex from the MHC molecule alone, the peptide alone, and a complex of MHC and irrelevant peptide.  Finally, the desired antibodies are isolated.

Abstract: A cyclonic separator (100) and methods of cyclonic separation which provide for a band pass separation of particles. That is, a cyclonic separator able to remove particles from an air stream that are greater than a predetermined minimum (which is greater than zero) while being smaller than a particular maximum. This band pass separation may be performed with the inclusion of a secondary vortex break (111) on a cyclonic separator. Also discussed are cyclonic flow systems which provide for less deposition of aerosolized particles onto the cyclonic flow generator and related structures to improve likelihood of particles of interest being provided to an attached detector.

Abstract: The pump has a hydraulic control chamber disposed between a piston (8) and a diaphragm (3). A chamber leak compensating unit has a refilling duct (14) opening out into the chamber via a valve (15). The valve is driven by pressing the diaphragm against a free end (16a) of a rod (16) to control the valve.
