Patent CA-2040306-C (CA)
Inventor: FUKUNAGA TETSUYA
IPC: G03F1/72
Filed: 1991-04-12
Granted: 1994-07-05
Abstract: The disclosure deals with color filters used in liquid crystal devices and, more particularly, with the repair of defects.   When  a  given defect  is  one  color,  the defective  portion  is  filled  with  a  negative type photosensitive resin of the same color as the defective pixels.   When a defect extends over pixels of various different colors,  the defective area is filled with a negative type photosensitive resin of gray.   Repair is readily effected since  self-alignment can be  achieved using the filter as a photomask.

IPC: G10L19/06
Filed: 1991-10-10
Granted: 1996-05-21
Abstract: Frequency  components  are  calculated  from the  STP-filtered speech signal.  The amplitudes of these are combined in a manner such that the resultant values are associated  with   frequencies   which   are   situated equidistantly on a linear Bark scale. Said components are quantised, possibly after scaling. In the decoder, the components are again distributed over the frequency spectrum. In the coder, the fundamental regularity D is determined with an LTP technique, after which it is transmitted. In the decoder the phases of the reconstructed signal at the spacing D in the past are determined. These phases are combined with the amplitudes already present in the frequency spectrum, after which transformation back to the time domain takes place. Inverse STP filtering is then carried out.

Title: Fabricated faucet spout
Inventor: MCTARGETT CHARLES W
IPC: E03C1/04
Filed: 1992-01-16
Granted: 1997-06-03
Abstract: An  improved  fabricated  faucet  is  disclosed  in  which  no mounting screws are visible when the spout is mounted.  In a preferred embodiment an under cover has  a notch  received on a  tab within an internal surface of an upper cover to secure the two at a forward end. Screws preferably secure the two at a rearward end, which will be hidden when the spout is mounted.  For longer spouts it may be preferable to use two of the notch and tab combinations spaced symmetrically about a central axis of the spout.  Ribs formed on the upper cover may abut the under cover to provide additional rigidity.   In another aspect of the present  invention,  an  outlet  end  portion  of  a  fluid  flow  line  is received in an outlet port formed through the under cover.  The outlet end portion has threads at an inner periphery to mount an end effector, such as an aerator or a stream straightener.  A sealing ring is received at the outer periphery of the outlet end portion to provide a fluid seal between the outlet end and the under cover body.  This allows the faucet spout to be utilized without internal leakage even if the end effector is removed.

Patent CA-2094680-C (CA)
Inventor: SCHMIDT WARREN E
IPC: F16F9/00
Filed: 1993-04-22
Granted: 2002-10-08
Abstract: A mounting (20) which provides superior isolation yet which eliminates damaging edge-induced shear strain (ENT) buildup in the elastomer sections (28) and (30) when exposed to high temperatures by having a first elastomer section (28) loaded in compression and a second elastomer section (30) loaded in shear. Exposing the mounting (20) to elevated temperature environments allows the first elastomer section (28) to expand in height and places the second elastomer section (30) in shear to accommodate the height change. The instant invention compensates for fluid and elastomer expansion due to high temperatures by providing a mechanical type compensator (37) which takes up less space and eliminates the pressure loss associated with air-charged compensators (99). Further, a unique combination of fluorinated fluids and polysiloxane polymer enables the mounting (20) to withstand temperatures of greater than 200 deg F for extended periods of time.

Un anticorps de rongeur humanisé qui présente l'apparence d'un anticorps humain est prédit par remplacement du jeu de résidus d'acides aminés exposés en surface de l'anticorps de rongeur ou d'un fragment de celui-ci par le jeu de résidus d'acides aminés exposés en surface de l'anticorps humain. Un modèle en trois dimensions peut alors être élaboré à partir de la région variable entièrement substituée résultante de l'anticorps de rongeur ou de son fragment.

The head is formed with a resiliently deflectable tab or flap (15) for frictional engagement with the shaft, to hold the head in secure axial position on the shaft. The terminal end (19) of the shaft (6) is convex, essentially ball-shaped or part-spherical. Preferably, a guide ring or guide surface (23), having the diameter of the shaft, is positioned between the circumferential or ring-shaped groove (18) and the ball-shaped or spherical end (19). The .groove (18) is shallow, wider than deep, and preferably, in cross section, part-circular. The circle has a radius of curvature of preferably between about 75% to 150% of the diameter of the shaft (6) on which the operating head is fitted.
