PURPOSE:To save the labor for working processed by using a resinous material for a hole where an optical fiber is inserted and using a ceramic material with wear resistance for the outer peripheral part of a ferrule which slides in a sleeve. CONSTITUTION:The outer peripheral part 2 of the ceramic ferrule is ground accurately circularly by a centerless grinder such as a diamond grindstone. A chip 3...

PURPOSE:To complete the function of a ferrule and to improve its accuracy by sintering a ferrule made of ceramic and then performing external-diameter working, and installing a pipe which has an extremely thin hole diameter movably in the hole of the ferrule, and making the coaxial extent between the extremely thin pipe and the outer periphery of the ferrule accurate by using a filler. CONSTITUTIO...

PURPOSE:To complete the function of a ferrule and to improve its accuracy by performing external diameter working after sintering a cylindrical body which is made of ceramic and has an untreated hole, blocking the end part with a filler material, and boring a hole in the filler material to the diameter of an extremely thin hole and obtaining the insertion hole diameter of an optical fiber. CONSTIT...

PURPOSE:To complete the function of a ferrule and to improve its accuracy by siting an extremely thin pipe in the center part of the conic internal hole of ceramic, inserting an optical fiber into the extremely thin pipe and positioning it in a state wherein attenuation is least, and injecting fused resin into the gap part. CONSTITUTION:The optical fiber 1 is interposed in the internal hole of the...

PURPOSE:To complete the function of a ferrule and to improve the accuracy by inserting and fixing an independent extremely thin pipe in the unpolished hole of ceramic which is formed being sintered and has the hole in the center part and thus determining the internal diameter of a ferrule for an optical fiber. CONSTITUTION:The hole 3 of ceramic after sintering is unpolished and left as a blank hol...

PURPOSE:To complete the function of a ferrule and to improve the accuracy by inserting a pipe (extremely thin pipe) which has an extremely small though hole diameter into the unpolished internal hole of cylindrical ceramic and exposing an end part of the extremely thin pipe to the outside from the internal hole of the ceramic. CONSTITUTION:An optical fiber 1 is inserted into the internal hole of t...

A device for iontophoretic delivery of active ingredient to a patient, that includes an electrode, a first cavity for holding a solution of at least partially active ingredient in ionizing form to be delivered to a patient, a member for maintaining a solution in the first cavity while allowing passage of active ingredient from the first cavity, and an ion exchange member separating the electrode a...

Fixing element for hanging attachments, the fixing of labels or the like, comprises a sleeve into which a plug can be inserted and a filament connecting plug and sleeve. All these components are made integrally of thermoplastics. In its initial form, before use, the filament is folded at the centre and the end of the plug is attached to the side or external portion of the sleeve by an easily broke...

A programmable cell 52 for use in programmable electronic arrays 50 such as Prom devices, logic arrays, gate arrays and die interconnect arrays has a body 68 of phase changeable material with a highly non- conductive state settable and substantially non-resettable into a highly conductive state by applying a threshold voltage of 20 volts or less, a current of 25 milliamps or less, for 1000 microse...

Method of connecting a battery plate to a battery strap or post in a mould 50 provided with a number of separate mould cavities 51 arranged on each side of a duct or channel 52 for receiving molten lead. Between each mould cavity 51 and the channel 52 is positioned a weir or barrier 60 which determines the level of lead in each cavity. Lead pumped into the channel 52 flows into the cavities 51 ove...

A stack of sheets arranged in an input stacker pass through a nip formed by cooperating feed rollers and stripper assemblies, which serve to separate sheets and feed them one at a time toward an acceleration assembly comprised of acceleration roller and cooperating idler means to form a gap between adjacent sheets for counting the sheets. The accelerated sheets are then fed into an output stacker....
