Recommended Apparatus to Improve Fibers’ Fusion-Splice Equipment
Fibers’ splicing is one of the essential and critical procedures for fiber optics and photonics devices, modules and networks. The purpose of this paper is to present a recommended apparatus which allows reducing the frequency to clean the electrodes of the fusion – splicer equipment when Corning’s erbium doped fibers are spliced together or to other type of all-silica fibers. Also, this recomm...
متن کاملA Uniform Pressure Apparatus for Micro/Nanoimprint Lithography Equipment
Nanoimprint lithography (NIL) has overcome the limitation of light diffraction. It is capable of printing features less than 10nm in size with high lithographic resolution, high manufacturing speed, and low production cost. The uniformity of pressure, however, remains a critical issue. To improve the uniformity of pressure, we developed a flexible uniform pressure component based on Pascal’s La...
متن کاملEquipment repaired is equipment gained
According to WHO, at any one time, around 50 per cent of medical equipment in lowand middle-income countries cannot be used because of lack of maintenance or spare parts.1 We have found that unwillingness or inability to repair equipment and put it back in use is also a major cause. New equipment is made available by different international non-government organisations (INGOs) competing with on...
متن کاملClosed-Loop Measurement of Equipment Efficiency and Equipment Capacity
Formal definitions for the components of efficiency and capacity, mathematical formulas for computing overall efficiency, and data collection strategies are proposed for rigorous measurement of equipment efficiency and equipment capacity. Measurement of overall equipment effectiveness (OEE) under the TPM paradigm is revised to become a true quantitative measure of efficiency that we term overal...
متن کامل[Development of an experimental apparatus for energy calibration of a CdTe detector by means of diagnostic X-ray equipment].
Diagnostic X-ray equipment was used to develop an experimental apparatus for calibrating a CdTe detector. Powder-type samples were irradiated with collimated X-rays. On excitation of the atoms, characteristic X-rays were emitted. We prepared Nb2O5, SnO2, La2O3, Gd2O3, and WO3 metal oxide samples. Experiments using the diagnostic X-ray equipment were carried out to verify the practicality of our...
