structural aspects of ball milled cds and cdse

the structural effects of ball milling powders of cds and cdse have been investigated by x-ray diffraction. when initially wurtzite-phase material was ball milled, excessive broadening and the selective extinction of certain diffraction lines were observed in debye-scherrer diffraction photographs of cds and diffractometer traces of cdse...

tatung tcs 7000

the tatung tcs-7000 is a good all-rounder. it is adequately if not exceptionally cheap, fast and well-designed: a balance of virtues that few other at compatibles can match. the finish is good judged by the standards of most smaller manufacturers, but not up to that offered by companies like ibm, epson, wang and olivetti. the relatively p..

design and performance of a magnetic read/write head for a digital tape drive

the authors consider the design and performance of the read/write head for an ibm type 3480 magnetic tape drive. dimensions have been reduced and track density increased to 18 tracks on a half-inch tape. the flux detector consists of an 81 percent nickel 19 percent iron magnetoresistive element with titanium pre-magnetisation bars and alu..

further discussion of the d-35x specifications (smt)

defines a silkscreen outline for a 16-pin small outline integrated circuit (soic) device and adds the reference designator text to the final picture

improved printer tooling for high volume automated production of thick film through hole circuitry

the adaptation of thick film through hole processing to already existing automated loaders and printers required the reevaluation of the substrate location system (also referred to as snugging system). through the use of air bearings for mechanical location and reflective optic sensors for correct alignment verification, gte developed a t..

a system to create computer-aided art patterns

an attempt was made to apply ai techniques in creating art patterns for printing on silk, cotton and other printed matters. the computer aided creation of art patterns system which can swiftly deliver various nice art patterns has been implemented on a microcomputer. this system consists of two subsystems in cascade the first subsystem is..

recent applications of printing technology

videodiscs, packaged cd-rom and cd-i developments are reviewed. paperless publishing using holography including multiplex, lipmann type, rainbow type and emboss holography is described typical products are credit cards, prepaid cards and silk printing correction systems in softcopy systems for trial runs (toppan cp-525, fc-600, ss-512) an..

intracavitary hyperthermia' construction and heat patterns of individualized vaginal prototype applicators

patients who have inoperable or previously irradiated cervical recurrences, especially if very confined and alone, pose a challenging problem to the clinician. low-dose irradiation and hyperthermia seems to be a promising method for salvage treatments in previously treated patients. in order to heat the vaginal apex, individualized protot..

hypercard-what is it{ (life science education)

hypercard was released by apple computer and is a 'software erector set'. it is a means by which individuals who have never programmed a computer can do so. hypercard is based on the concept of hypertext. hypertext is a system of transferring information by means of a computer rather than books or other print media. the author explains ho..

edge face trimming of bare boards

fine edge finishing should be a part of every pcb maker's qa program. the need for edge face trimming of bare printed circuit boards is not widely appreciated. if the dangers of raw panel edges were clearly understood, however, fine edge finishing would be mandated immediately as part of every pcb maker's quality assurance program. in som..
