Abstract: In a connection fitting for clamping and gluing pieces, especially wooden plates (1/2), at their abutting surfaces, such as for example door linings in the mitre corners, consisting of a metal strap (4) which engages, at one end with a clamping device (8/9) and at the other end with a countermovement angle (5), into particularly rear cutouts, for example pot-shaped bores (3) of the wooden pieces (1/2) to be joined to one another, the said connection fitting is to ensure an improved pressing pressure and hence be capable of effecting clean and permanent gluing of the wooden plates (1/2). For this, the clamping device has a clamping member (9) articulated pendulously on the metal strap (4) and an adjusting screw (8) pushing, from a preferably obtuse-angled edge (7) of the metal strap (4), the free portion of said clamping member (9) towards the countermovement angle (5) and intended for pressing together the wooden pieces (1/2) at their abutting surfaces. In this arrangement, the clamping member (9) can furthermore be guided in a loosely sliding manner in a longitudinal slot (11) arranged in the web (6) of the metal strap (4), in order to compensate for dimensional differences in the spacing of the cutouts (3) of the wooden pieces (1/2), and it is also particularly preferable if the countermovement angle (5) forms an acute angle with the web (6) of the metal strap (4). <IMAGE>

Abstract: A lightwave component analyzer and method for determining chromatic dispersion in single mode optical fiber. The lightwave component analyzer initially performs various measurements that are used in the determination of chromatic dispersion in single mode optical fiber. The lightwave component analyzer then computes a chromatic dispersion factor using the measured parameters, as well as additional parameters which are stored in the analyzer or entered by a user. Various expressions are described for computation of chromatic dispersion in single mode optical fiber.

Abstract: Top surface emitting, vertical cavity lasers depend upon emission through apertured top surface electrodes (23). Biasing current, which is thus peripheral to the laser as introduced, follows a path (25) which comes to confluence within the active gain region to effectively attain lasing threshold. The path is a consequence of a buried region of increased resistance (shaded in the drawing) which encircles the laser at or above the active region (13). The buried region is produced by ion implantation-induced damage with ion energy magnitude and spectrum chosen to produce an appropriate resistance gradient. Integrated, as well as discrete, lasers are contemplated.

Abstract: A frequency division network is disclosed in which a sinusoidal signal is converted to a digital format for frequency division and then converted back to the sinusoidal format, the sinusoidal output wavefrom having low phase noise. In a preferred embodiment the frequency conversion takes place in an m-fold plurality of edge triggered flip-flops, connected to divide by two, and clocked by the sinusoidal waveform. Each flip-flop is subject to jitter causing phase noise, which is minimized when the output of two sets of four flip-flops are averaged, and then filtered to obtain the sinusoidal fundamental. When a crystal filter having a very narrow pass band is employed, the phase noise is further reduced. The frequency division network uses low cost components and the phase noise of the output waveform approaches that of a stable crystal oscillator.

Abstract: A method and apparatus for operating an electronic reprographic system upon detection of a fault are described. Original documents of a job to be printed are scanned (6) to provide images for storage. When scanning is interrupted, the last-captured image is stored and selectively displayed. If scanning is not completed before the interruption, the system is monitored for the occurrence of a fault before scanning is resumed. The detection of a fault occurrence requires clearance of the paper path before scanning operation can be resumed. If scanning is completed, printer (8) operation is enabled to provide image output. Partially-completed scan jobs resulting from scanner interruption are saved in operator-accessible memory (61).
