Patent CA-2118515-A1 (CA)
Title: Biodegradable scleral plug
Inventor: OGURA YUICHIRO
IPC: A61K9/00
Filed: 1994-02-23
Abstract: ABSTRACT    The present invention relates to a scleral plug made of lactic acid copolymer; a scleral plug containing a drug that is designed to gradually release the drug into a vitreous body; and a scleral plug that is used to treat or prevent diseases of the retina or to promote recovery from damage after vitreous surgery taking advantage of its sustained release action for drug delivery.    The scleral plug of the present invention plugs the incision after vitreous surgery and is not needed to be removed.  The scleral plug enables a drug to be administered safely and effectively in intraocular tissues, where drugs barely distribute, by releasing a drug gradually for a long period.  Moreover, it is possible to find other conventional methods for administering a drug, e.g., a method involving the use of a scleral incision which is formed during vitreous surgery.

Inventor: HANNA JAMES A
IPC: G09F7/16
Filed: 1994-03-24
Abstract: An improved method of identifying emergency exits in public buildings in the event of fire, power failure, or similar emgency. The signs are affixed to the lower portion of exit doors and corridors leading thereto which are more visible than conventional overhead signs, due to the rise of smoke and pooling near the ceiling in a fire. The signs are of retro-reflective material which returns light to a light source, such as a flashlight, and the colours utilized are morevisible to the human eye than conventional red exit signs.

Title: Thin film transducer with reduced flying height
Inventor: LIN FONG-JEI
IPC: G11B5/31
Filed: 1994-05-12
Abstract: ABSTRACT OF THE DISCLOSURE           A magnetic disk recording system with a combination transducer/slider having reduced effective flying height as measured between the transducer gap and the surface of the recording medium.  The slider has a leading end, a trailing end and an air bearing surface extending therebetween.  The trailing end is provided with a surface contour which forms a boundary with the air bearing surface near the pole tip region of the transducer.  Consequently, the effective flying height of the pole tip region is nearly equal to the flying height of the boundary.  The contoured surface can be an angled plane, a transverse notch or a thin overcoat layer with a small angled band.  The magnetic transducers may either have flat bottom poles or a bottom pole with a recessed central region.

Abstract: A swaging station incorporates a drawing tower that automatically draws, cuts, and inserts an indefinite length strand of suture material within the suture receiving end of a surgical needle for swaging thereof.  The suture receiving end of the surgical needle is positioned within a swaging assembly located at the top of the drawing tower that comprises a first fixed swage die and a second movable swage die forming a swage die opening for positively gripping the suture receiving end of the needle positioned therein.  A first suture alignment die and a second suture alignment die are precisely registered below and adjacent the respective first and second swage dies to form a lower funnel guide that is axial with the swage die opening for positioning the tip of the suture strand therein. The lower funnel guide has an exit diameter that is larger than the diameter of the suture tip and smaller than the diameter of the suture receiving end of the needle for easy placement of the suture tip therein. Subsequently, the second movable swage die is actuated to swage the suture tip to the needle.

Abstract: Lithographic printing constructions and methods of imaging them[ are disclosed]. The constructions include a grained-metal substrate, a protective layer that' can also serve as an adhesion-promoting primer, and an ablatable oleophilic surface layer. In operation, imagewise pulses from an imaging laser interact with the surface layer, causing ablation thereof and, probably, inflicting some damage to the underlying protective layer as well. The imaged plate may then be subjected to a solvent that eliminates the exposed protective layer, but which does no damage either to the surface layer or to the unexposed protective layer lying thereunder. <IMAGE>
