Determining Spectral Sensitivity Of Kodak Micro Positive Resist 820, Matthew L. Huck Apr 1983

Determining Spectral Sensitivity Of Kodak Micro Positive Resist 820, Matthew L. Huck

Theses

The spectral sensitivity of KODAK Micro Positive Resist 820 has been determined for the spectral range of 300nm to 500nm. A xenon-source monochrometer was used in a hard contact exposing system. Se/isitivity is defined as the inverse of the exposure (mj/cm ) needed to produce an image in a photoresist coated plate having walls of 70 normal slope. Low intensity reciprocity law failure has been conclusively shown to exist in this resist with exposure intensities of 100 mw/cm and below. Guide lines have been drawn up, based on the procedures and results of the experimentation, to assist photoresist users in …


Evaluation Of The Photographic Characteristics Of Emulsions With Different Iodide Percentages, Joseph M. Sharp Apr 1983

Evaluation Of The Photographic Characteristics Of Emulsions With Different Iodide Percentages, Joseph M. Sharp

Theses

Ammonia-converted iodobromide emulsions with 0, 1, and 5 mole% iodide were prepared with a single-jet precipitation procedure to the same grain-size distribution. After development to gamma-infinity with high-solvent and low-solvent type developers, photographic characteristics were determined and are reported here. Iodide affects absorption of light in an emulsion, but when corrections are made for this change in absorption, iodide does not change the basic sensitivity of sulfur-sensitized emulsions.

The Effect Of Microscope Scale Reticle Design On Variance Of Measurement, David D. Rockafellow Apr 1983

The Effect Of Microscope Scale Reticle Design On Variance Of Measurement, David D. Rockafellow

Theses

Little work has been documented regarding the design of optical instrument scale reticles. Reticle is the word used to describe both scales and crosshairs used in the eyepiece of an optical instrument. An ergonomic (the relation of man to his working environment) experiment was performed in which thirteen different scale reticles were designed, manufactured and tested. The design parameters tested were scale spacing, line height, and line thickness. The testing consisted of thirty observers measuring a circular test object through a microscope with each scale reticles. The results, taking into consideration both variance in measurement and observer comments, showed the …


Industrial Art Materials, Frank S. Defrancis Apr 1983

Industrial Art Materials, Frank S. Defrancis

Theses

Anyone, who has ever tried to paint has become well acquainted with the fact that huge sums of money too often buy the meagerest amounts of supplies. Faced with the possibility of either breaking into art supply stores at night or learning to vent my hostilities elsewhere I traded my studio supplies for their industrial counterparts and gratefully have never looked back. The following report will document the advantages as well as the disadvantages that I have encountered in working exclusively with industrial art materials. The first half will deal the materials themselves while the second half will offer a …

A Mathematical Model Of Halftone Reproduction Including The Effects Of Optical And Chemical Spreading, Cort Demmert Apr 1983

A Mathematical Model Of Halftone Reproduction Including The Effects Of Optical And Chemical Spreading, Cort Demmert

Theses

A system which predicts halftone reproduction curves for film-developer combinations, based on the combined optical and chemical modulation transfer function for that combination, has been tested using a 100 cycle/inch contact line screen. Density in fine detail is predicted and used to determine fractional area data. Predicted fractional area data was found to lie within 95 percent confidence intervals of experimental fractional area data.


Design Of A High Ratio Gear Reduction Unit, Jean Xydias Apr 1983

Design Of A High Ratio Gear Reduction Unit, Jean Xydias

Theses

This is a right angle gear drive design where helical and spiral bevel gears are being used. Because of the high speed ratio (1800/18 , input/output), three reductions were applied. Two helical gear sets were used in the first and second reductions (one each), and a spiral bevel set was used at the final reduction. The gears were mounted on four shafts, with the first and last shafts (output and input shafts) carrying one gear each straddle mounted, and the second and third shafts carrying two gears each, overhung mounted. The design was based on a criterion that was set …

Sounds In Clay: A Study Of Vibrating Ceramic Sculpture, Ward Hartenstein Mar 1983

Sounds In Clay: A Study Of Vibrating Ceramic Sculpture, Ward Hartenstein

Theses

The purpose of this thesis is to derive a synthesis of the sculptural aspects of form and structure and the physical principles of musical acoustics. vibrating systems: Specifically I wish to deal with three types of free-end vibrating bars; fixed-end vibrating bars; and three-dimensional vibrating bodies, each of which possesses a unique set of technical constraints within which the aesthetic requirements of form and structure may be addressed. My objective is to conduct research leading to the design and construction of a group of objects which, through the involvement and participation of the viewer, communicate both a visual and an …
