Method For Producing Conductive Or Insulating Feedthroughs In A Substrate, Janet K. Lumpp, Susan D. Allen Dec 1996

Method For Producing Conductive Or Insulating Feedthroughs In A Substrate, Janet K. Lumpp, Susan D. Allen

Mechanical Engineering - Daytona Beach

A method for producing feedthroughs in a substrate having a front and back surface, wherein the substrate either has a hole or absorbs radiation at a given wavelength. The method includes selecting and intimately bonding a sheet to the back surface of the substrate with an adhesive which is absorptive at the given wavelength. If the substrate has a hole, an exposed area of the sheet is illuminated with laser radiation at the given wavelength and at a power level sufficient to ablate a portion of the sheet behind the exposed area, thereby creating the feedthrough in the substrate. If …


Apparatus And Method Of Fabricating Directional Fiber Optic Taps, Sensors And Other Devices With Variable Angle Output, Susan D. Allen, Changhun Lee Mar 1996

Apparatus And Method Of Fabricating Directional Fiber Optic Taps, Sensors And Other Devices With Variable Angle Output, Susan D. Allen, Changhun Lee

Mechanical Engineering - Daytona Beach

An apparatus and method for fabricating directional fiber optic taps having a variety of output angles. The taps can be used to monitor losses due to misalignment of the fiber or losses due to bending and straining of the fiber. The apparatus and method can also be used to fabricate taps which filter out higher order modes in a fiber. The apparatus and method can also be used to produce taps which can be used in a position or refractive index measuring system.


Running With The Pack: Jit & Automation For Small Manufacturers, Thomas E. Phillips, John R. Ledgerwood Jun 1994

Running With The Pack: Jit & Automation For Small Manufacturers, Thomas E. Phillips, John R. Ledgerwood

Publications

While both just in time (JIT) concepts and automation programs have been widely implemented and highly successful in large manufacturing companies, many smaller manufacturing companies have wondered whether it would be economically feasible to utilize these same techniques and derive these same benefits. When JIT is adopted by small manufacturers, it provides them with advantages over traditional manufacturing systems, such as lower cost, quality improvements, higher productivity, and less working capital tied up in inventory. Small US manufacturers must understand the basic principles and philosophy of JIT and update their production equipment if they are to be competitive in today's …
