Abstract: A method of manufacturing endodontic files (10) involves a chemical milling process to yield endodontic files having a desired degree of sharpness. The chemical milling process forms a tapered portion (18) of the endodontic file (10). The process involves the steps of (a) forming helical cutting edges in the cutting portion of the metallic rod (12) and (b) chemically milling the cutting portion (18) of the rod (12) so as to at least sharpen and optionally taper the cutting portion (18). The rod (12) may be formed of any desirable metallic material, for example stainless steel or a nickel titanium alloy. The cutting edges may be formed by torsioning, cutting, grinding, machining, laser micromachining, or grit blasting. Chemical milling can also remove cracks or microfissures, yielding more contiguous cutting edges that better resist cracking or breakage.

Title: A reading device for a record carrier

Abstract: The invention provides an efficient reading device in which, even if one radiation beam should fail, no information is lost and the information can still be read out without time-consuming recurring operations. The present invention solves this problem by providing a reading device (Fig. 5A) and a means (Fig. 4) for forming read-out spots (A, B, C, D, E) that are built up by multiple radiation beams from the radiation source (4). This has the advantage that each read-out spot will have energy contributions from different radiation beams and, should one radiation beam break down, the intensity of some of the read-out spots may indeed diminish, but the information can still be read out thanks to the contributions from other radiation beams.
