Abstract: A method of making an optical fiber having a strippable polyimide coating includes the steps of drawing an optical fiber through curable polyamic acid solution to form a coating on the fiber and curing the coated fiber. The cured coating can subsequently be stripped from the optical fiber by exposing the cured coating to an organic polar solvent such as acetone. A fiber having a strippable polyimide coating is also provided. The method is particularly applicable to heavy metal fluoride fibers, and to chalcogenide fibers which carry optical signals in the infrared region.

Abstract: A die for use in a stage of a multi-stage die-necking process of a metal body such as a beverage can, has a surface around a center-line. The die surface, seen in longitudinal section through the center-line, has a profile which includes in direct succession a feed-in zone, an intermediate zone and a neck zone. The intermediate zone has, as well as a contact part, a relatively steep part in which tangents to the die surface include an angle .alpha. to the center-line greater than .alpha..sub.n, where .alpha..sub.n is the neck angle between the necked part following die-necking and the center-line of the body. The presence of this non-contact steep part reduces the axial force needed in the die-necking.

Abstract: A cold cathode fluorescent discharge tube is provided having, as an anode standing for one of discharge electrodes, a mercury discharge structure comprising a metal sintered body formed by sintering powder of a high melting point metal such as titanium, with mercury combined with the metal sintered body. The mercury discharge structure is so formed as to contain a large amount of mercury and is therefore permitted to have a compact shape in order to obtain a requisite amount of mercury. The cold cathode fluorescent discharge tube permits a sufficient amount of mercury to be sealingly incorporated in the interior of the tube without decreasing the ratio of the effective luminescent length to the total length, having suitability to diameter reduction, and can be produced at low cost.
