Abstract: Continuous silicon carbide fibers are known and can be produced by spinning a polycarbosilane, rendering the spun fibers infusible, and then firing them. 
     The invention provides continuous inorganic carbide fibers having better physical properties than known silicon carbide fibers, the fibers ofthe invention consisting substantially of Si, Ti and C and optionally of 0, and being composed of (1) an amorphous material consisting substantially of Si, Ti and C and optionally of O, or (2) an aggregate consisting substantially of ultrafine crystalline particles of β-SiC, TiC, a solid solution of β-SiC and TiC and TiC 1-x  wherein 0 <x< 1  and having a particle diameter of not more than 500 A, in which amorphous Si0 2  and Ti0 2  exist in the neighborhood of these ultrafine crystalline particles, or (3) a mixture of said amorphous material (1) and said aggregate (2) of ultrafine crystalline particles. These continuous inorganic fibers can be produced by spinning fibers from a dope of a semi-inorganic block copolymer comprising polycarbosilane blocks having a main chain skeleton composed mainly of carbosilane units of the formula (-Si-CH 2 -), each silicon atom of said carbosilane units having bonded thereto a side-chain atom or group selected from hydrogen, lower alkyl and phenyl, and titanoxane units of the formula (-Ti-O-); rendering the spun fibers infusible, and firing the infusible fibers at a temperature of 800 to 1800°C in vacuum or in an atmosphere of an inert gas or a reducing gas.

Abstract: Documents are stacked face up in an upper tray 80 and moved as a group to a lower tray 96 where they are stacked face down, with the first document in the upper tray appearing in a face down position at the bottom of the lower tray. The top document in the lower tray is then removed for copying and returned to the bottom of the upper tray, thus preserving the original document order for further copying. The copier normally scans stationary documents placed on a glass platen 23, for example, individual sheets of paper or book pages may be placed on the glass platen and held stationary while the optics cause light to scan the page. During automatic recirculation of stacks of the documents, the scanning optics is "parked" and documents removed from the lower tray are imaged while scanned past a fixed exposure area 142 on the glass platen on the way back to the upper tray.

IPC: H03M1/00
Filed: 1982-06-28
Abstract: The invention lies in the field of converting analog AC signals to digital signals which then, for example, are transmitted by use of the pulse code modulation method. The circuit arrangement contains sampling means (S1) which cyclically sample the analog AC signal and form analog sampling values, and an analog-digital converter (A, STS, DAU, KOM) for converting the analog sampling values to digital sampling values. Further the circuit arrangement contains a sign integrator (VZ, HZ) which integrates the sign of the digital sampling values, a compensating voltage generator (DAU), which generates a compensating voltage in dependence upon the integration result and a combination circuit (KOM), which combines the compensating voltage with the analog sampling value from the sampling means and applies the combination result to the analog-digital converter. The circuit arrangement permits compensation of a DC voltage component contained in the analog AC signal so that interferences are avoided which are the result of such a DC voltage component.
