Title: Incrementor absolute revolution sensor with clamping means
IPC: G01D11/30
Filed: 1987-10-09
Granted: 1991-12-11
Abstract: An incremental or absolute rotation encoder with a clamping device for connecting the encoder shaft to the drive shaft of a drive unit by means of a radial clamping action. A clamping element with a first sliding surface which is inclined relative to the axis of the encoder shaft is provided resting against a corresponding second inclined sliding surface at the end of the encoder shaft facing the connection with the drive shaft. An actuating element is capable of acting on the clamping element in axial direction. Since the two inclined surfaces rest slidingly on each other, the clamping element and the end of the encoder shaft are pressed in opposite radial directions against the drive shaft.

Abstract: A sensor-controlled levelling device comprises a position detector (2) and/or a laser sensor 30. To create a sensor-controlled levelling device by means of which a desired relative position can be automatically set and held in an accurately controlling manner, it is provided that in the case of the position detector (2) the float (5) provided there is supported and mounted in a centre area (3). The laser sensor (30) comprises a zero point detection with subsequent analysing electronics for at least one actuator (79; 78, 80). The actuator (79) can be countercontrolled in opposition to a relative position change of the laser sensor (30) compared with the reference plane (R) defined by a laser generator in the sense of a tracking of the laser sensor (30) to the reference plane (R) (Figure 3a).

Abstract: A light source throws a light beam through a transparent scale provided with graduation lines. The light beam is focussed by means of an aperture in such a way that it is disposed at an inclined angle with respect to the graduation lines. Upon relative displacement as between the scale and the aperture, that arrangement provides that a constantly changing light beam is projected onto a photosensitive receiving means. Depending on the respective position and configuration of the light beam on the receiving means, it is possible to arrive at the relative position of the scale within a travel increment.

Abstract: Une peinture de qualité automobile (44) est appliquée en couches sur la surface extérieure d'un élément ou panneau (118) de carrosserie automobile en plastique moulé. Dans un mode de réalisation, la peinture (44) comprend une couche claire extérieure (45) au-dessus d'une couche colorée (46). Pendant le traitement, la couche claire (45) et la couche colorée (46) sont chacune déposées sur une feuille coulée (42) souple provisoire et séchées. Une surface de brillance élevée est transférée à la couche claire (45) à partir de la feuille coulée (42). La couche de peinture (44) est ensuite transférée de la feuille coulée (42) à une mince feuille de support (72) en plastique thermoformable semi-souple, par des techniques de stratification pour le transfert de peinture sèche. Le stratifié résultant (70) est thermoformé pour obtenir une configuration tridimensionnelle complexe de l'élément ou panneau de carrosserie. Le stratifié préformé (116) est ensuite adhérisé au substrat plastique sous-jacent, par des techniques de placage par injection, par exemple, en vue de former l'article fini. La couche de peinture (44) présente un allongement suffisant pour conserver un aspect extérieur digne de la qualité automobile et des propriétés de durabilité pendant le thermoformage, sans perte de brillance. La feuille de support (72) absorbe les défauts du substrat, de sorte que la couche de peinture conserve son aspect et ses propriétés de durabilité pendant l'étape de placage par injection. L'article fini comporte une couche de peinture, de brillance élevée et exempte de défauts, sur l'extérieur d'un élément ou panneau de carrosserie en plastique moulé. Des systèmes de peinture acrylique/polyfluorure de vinylidène sous forme de solution allient une brillance remarquablement élevée à une classe exceptionnelle, conjointement à la durabilité requise pour l'emploi à l'extérieur en carrosserie automobile.

Abstract: Areas in an optical disk (101) are classified into three kinds of areas: file areas, used areas, and erased areas. An erasing process to convert the used area into the erased area is executed asynchronously with a writing process, thereby preventing the decrease in data transfer speed due to the erasing process upon writing process. On the other hand, the file areas, used areas, and erased areas are managed on every continuous areas which are designated by the head position and the size or end position of the area. The file is preferentially assigned to the erased area or used area of a large size. With such a construction, the area management such as an integration of the erased area or the like can be performed and the file can be assigned to the continuous areas and the access speed can be improved.
