Title: Morgan neddle biopsy guide
Inventor: MORGAN DONALD A
IPC: A61B17/34
Filed: 1993-04-06
Abstract: ABSTRACT     An apparatus I call the "Morgan Needle Biopsy Guide" is for use in Medicine, particularly for biopsy of the prostate gland.  In recent years Biopsy Guns have been developed which are fast and require less anaesthetic but have a six inch long flexible needle which needs stabilization and guiding to the tissue being biopsied.  The "Morgan Needle Biopsy Guide" is made of surgical stainless steel in two parts welded together.  The first part is a slim tube than can accommodate the biopsy needle, with a slight curvature to fit the relaxed index finger.          The second part is cut of malleable stainless steel, and has two nearly complete rings that go around the near and far end of the index finger like a sleeve.  They provide stability to the "Guide" and can be bent to fit snugly on different diameter fingers.  This piece also has a "spine" portion which runs the length of the index finger and onto the palm of the hand where it widens out to provide a guard to protect the users hand from the needle.  The palm end has a shoulder which the Guns fit up to, ensuring the needle is at appropriate length.

Abstract: ABSTRACT           A battery-operated flushing system (10) comprises a flushing valve (34) of the pilot-operated self-closing type having a pressure chamber (46) connected to a pilot conduit (52) controlled by a solenoid valve (50) of the non-latching type. A pressure control valve (48) is disposed between the pressure chamber (46) and the solenoid valve (50) for limiting the static water pressure applied to the solenoid valve (50) when the solenoid valve is closed.   The provision for the pressure control valve (48) enables considerable reduction in the power consumption required to lift a solenoid valve plunger against the action of the static hydraulic pressure.   Once the plunger is lifted, the non-latching type solenoid valve is energized with a reduced electric current sufficient to hold the valve in its open position.   In total, energy consumption per cycle of operation is reduced.   Use of the non-latching type solenoid valve permits to avoid malfunction inherently involved in the solenoid valves of the latching type.   Various other embodiments are also disclosed.

Title: Method and arrangement for arbitrary angle mirrors in substrates for use in hybrid optical systems
Inventor: GOOSSEN KEITH W
IPC: H01S5/00
Filed: 1994-08-23
Abstract: METHOD AND ARRANGEMENT FOR ARBITRARY ANGLE MIRRORS      IN SUBSTRATES FOR US IN HYBRID OPTICAL SYSTEMS          Abstract A method for forming, and an arrangement for using arbitrary angle mirrors in substrates is disclosed.  An erodible material, such as a photoresist, is applied to a substrate at a site and is exposed to radiation at that site which has a linear variation in energy at the surface of the erodible material.  Due to this variation in exposure energy, a taper results in the erodible material after development.  The tapered region is then etched in a manner which etches both the erodible layer and the underlying substrate.  The taper in the erodible layer provides a varying attenuation during the etching process such that the taper of the erodible layer, or a multiple of it, is transferred to the substrate. In a first embodiment, a tapered reflective surface is formed in a substrate, which surface engages an optical signal and deflects it to an optical device or another surface.  In a second embodiment, two tapered reflective surfaces are formed in a substrate and oriented to deflect incident light to a modulation device.  In a third embodiment, an arrangement for modulating a light signal is formed by two tapered reflective surfaces.  The surfaces are oriented to form a vee groove in a substrate and are coated with an active semiconductor device.
