Granted: 1994-10-11
Abstract: ABSTRACT OF THE DISCLOSURE An hydraulic chip breaking tool holder is provided with a fluid coupler and seal assembly for transferring high pressure, chip breaking fluid from an outlet opening of the main body of the tool holder to an inlet opening of an attached nozzle cap.  A coupler in the form of a dowel is interconnected between the openings.  At least one of the openings includes a seal cavity having an outer wall.  The dowel is inserted through the seal cavity.  A deformable pressure sensitive seal is disposed within the seal cavity and extends around the dowel.  The pressure of fluid passing through the tool holder causes the seal to radially expand and seal the area between the dowel and the outer wall of the seal cavity, thereby preventing fluid from escaping past the seal.

Abstract: A method for enhancing or restoring lacrimal function by the topical administration of a cyclosporin in a pharmaceutically acceptable excipient.  Lacrimal function is enhanced or restored in patients suffering from  abnormalities  of  the  tear  film  including  an absolute  or  partial  deficiency  in aqueous  tear production, called keratoconjunctivitis sicca or KCS, regardless of etiology, including autoimmune dysfunction of the lacrimal glands.  The treatment is also useful in  the  enhancement  or  restoration  of  normal  tear production, and normal healing of the surface of the eye.      The   preferred   composition    for   topical administration  to  the  eye  consists  of  cyclosporin dissolved in corn oil.   The composition may further include   antioxidants,  lubricants,    antibiotics, antifungals, antivirals, pilocarpine, vasoconstrictors, surfactants, wetting agents, anti-inflammatory agents (i.e. corticosteroids), preservatives, mucolytic agents (i.e. bromhexine,  acetylcysteine),  as well as other compounds.      The most preferred composition is 2% cyclosporin, 1 mole % alpha tocopherol and 0.005% methyl paraben in corn oil.

Abstract: EFFICIENT ENCODING/DECODING IN THE DECOMPOSITION AND RECOMPOSITION OF A    HIGH RESOLUTION IMAGE UTILIZING   ITS LOW RESOLUTION REPLICA Abstract More efficient encoding/decoding in decomposing and recomposing a high resolution image is obtained by employing a unique prediction arrangement. The prediction arrangement determines whether high resolution pixels to be recomposed from low resolution pixels from a low resolution replica of the high resolution are so-called typically predictable or non-typically predictable by using general prediction rules. The general prediction rules are also employed to determine if any of the typically predictable high resolution pixels would be improperly recomposed. Such high resolution pixels which would be improperly recomposed are identified as exceptions. It is noted that so-called supplemental information is required to properly recompose non-typically predictable pixels and typically predictable pixels which are identified as exceptions. To this end, exceptions accompany the low resolution pixel for which the corresponding high resolution pixels would otherwise be improperly recomposed. (FIG. 1).

Title: Tapered semiconductor waveguides and method of making same
Inventor: KOCH THOMAS L
IPC: G02B6/136
Filed: 1990-06-29
Granted: 1994-02-01
Abstract: TAPERED SEMICONDUCTOR WAVEGUIDES     AND METHOD OF MAKING SAME Abstract Adiabatic mode control and structural reproducibility are achieved by a tapered semiconductor waveguide structure wherein semiconductor guiding layers are interleaved with stop-etch layers and each guiding layer extends further along the propagation axis of the waveguide further than the guiding layer immediately adjacent thereabove to create a staircase-like core or guiding structure. Cladding regions of appropriate semiconductor material having a lower index of refractionthan the tapered core structure may be added to completely surround the tapered guiding structure. The profile of the tapered structure is realizable as any desired staircase-like shape such as linear, parabolic, exponential or the like. Additional layers of higher index of refraction semiconductor material may be included in the cladding region to permit additional beam shaping of the expanded spatial mode propagating along the tapered waveguide. Photolithographic masks defining successively larger exposed areas are aligned, deposited over the waveguide structure, and then removed following eachetching step. Material selective etching techniques are employed to remove exposed (unmasked) portions of guiding layers. In sequence, the exposed, formerly underlying portions of the stop-etch layers are then removed using material selective etching. Iteration of the above process steps permits a tapered waveguide structure to be defined.
