Abstract: This invention relates to a circuit for converting an analog audio signal to a highly resolving bit stream. An audio signal (U.sub.In) is converted on several parallel paths (1, 2) having different amplitude sensitivities into a data stream, where the offset of the individual paths (1, 2) is compensated for individually. Subsequently the amplification difference produced by the different amplitude sensitivities is determined and compensated for, so that one of the two data streams is made available as a bit stream for further processing. The selection of the data stream which is made available as a bit stream for further processing, is determined based on the amplitude of the audio signal (U.sub.In).

Abstract: A printer for application of droplets of hot melt ink on a substrate in order to generate characters or symbols thereon includes a compact and space saving housing containing a reservoir for supply of the hot melt ink in a solid state, a feeder for reception of the hot melt ink in the solid state form the reservoir, and a printhead having one or several discharge nozzles. Between the feeder and the printhead a chamber is provided in the housing and the feeder is adapted to feed the hot melt ink by means of positive displacement to the chamber while the ink is melted by a heater arranged in the housing. The printhead receives the hot melt ink in a melted state from the chamber and discharges it in the form of droplets from the nozzles for application on the substrate. The reservoir includes perforations to allow carrier gases to escape.

Abstract: The present invention refers to a can having a seam formed by a seaming process, through which it is possible to produce cans by seaming (fixing) tops and ends to bodies of cans by micro-seaming process. This seamed can is made by using materials with 0.16 mm thickness or less, with a high hardness DR8 or DR9 for making tops and ends. As a result of the micro-seaming process a significant reduction of dimensions has been obtained on the cover and body hooks and in the length of the seam, without changing volumetric capacity of the can.

Abstract: Herein disclosed is an endless hot rolling method using a hot strip mill substantially composed of a roughing mill and a finishing mill having a roll bender and a roll shifter to continuously roll sequentially joined different rolling materials. The method comprises the steps of: calculating a roll shift range in an axial direction for each rolling material so as to provide a desired crown; determining a rolling sequence so as to obtain a common roll shift range for each pair of neighboring rolling materials; connecting a preceding material at the tail end thereof to the head end of the succeeding material, between the roughing mill and the finishing mill; shifting the rolls during transition from the preceding material to the succeeding material so that the roll position corresponding to the joint of the two materials is within a common roll shift range for the materials; and changing the roll bending load in accordance with the roll shift pattern so as to achieve the desired crown of each material.

Abstract: In an optical pickup, a focus error detector for detecting a focus error of an objective lens for an optical disk includes a focusing lens for focusing the reflected light of the optical disk, a diffraction optical device for diffracting the reflected light focused by the focusing lens into two light rays, two bi-segmented photo-detectors for receiving the two split light rays, respectively, and a circuit for outputting a desired focus error signal from the signal detected from the photo-detectors. The circuit outputs a pure focus error signal without errors created by the deviation of the light amount in the photo-detectors due to the tilt or shift of the reflected light, thereby contributing to the stable operation and miniaturization of the optical pickup.

Abstract: In order to carry out the automated tapping of complex parts 10, such as helicopter blades, the surface to be inspected is subject to successive shocks using an impacting head 12 displaced in accordance with a given spacing or pitch. The sound produced by these shocks are collected by a microphone 16 associated with an acquisition circuit 18. At least two successive sound signals, which may or may not be consecutive, are compared in order to establish a fault diagnosis. The comparison and diagnosis are carried out by a neuron network or system, after the number of representative points of each sound signal has been reduced during a preprocessing involving a selection stage followed by a smoothing stage.

Abstract: The invention concerns a load-carrier for vehicles of the kind comprising a load-carrying tubular rail extending across the vehicle roof in the transverse direction of the vehicle, and a foot member at each lateral edge of the vehicle roof, said foot member resting on the upper vehicle roof face and serving as a load-carrying rail support. The purpose of the invention is to provide a load-carrier which is safely anchored to the vehicle roof also when the latter is not formed with safe support against outwardly directed forces, i.e. drip-mouldings, previously commonly provided on vehicle roofs.

Abstract: In a process of withdrawing castings while vertically oscillating a mold formed with long side walls and short side walls, the long side walls are moved apart from the castings by operating a hydraulic cylinder in the time zones for which the castings are applied with a large frictional force. On the contrary, the separated long side walls are made to move together to the casting in the other time zones for which the casting is not applied with the large frictional force. By repeating the separation and approaching of the long side walls, it is possible to obtain castings which are reduced in the depths of oscillation marks and suppressed in segregations at oscillation mark trough portions.
