Patent EP-0241694-A1 (EP)
Inventor: FIELD BRUCE F
IPC: A47L11/40
Filed: 1987-03-05
Abstract: There is disclosed an improvement in a surface maintenance machine (16) whereby means are provided for automatically maintaining a desired normal force by a maintenance tool (30, 32) against a surface being maintained, although there may be undulations in the surface, variations in the condition of the surface and changes in the tool caused by wear. Normal force is applied to the tool by gravity and an actuator (54), both acting through a load cell (44) which senses their algebraic sum, compares this with a preset desired force and operates the actuator as needed to maintain the force at or near the pre-set level. Further, the load on the motor or motors (34, 36) driving the tool is sensed and compared against high and low reference points. If drive motor load is outside of the reference limits a signal is provided which causes a decrease or increase in the normal force to maintain the motor load within limits.

Abstract: At least one continuously arriving product stream of printed products is to be transferred to the infeed paths or lines of two or more processing stations. To ensure that the distribution of the arriving product stream can be accomplished as continuously as possible and accommodated optimumly to the requirements of the processing stations, the product stream is guided such that it crosses the infeed paths. At the crossings or cross-over locations the product stream is at least periodically delivered to a storage device and at the same crossings or cross-over locations printed products are simultaneously transferred out of the storage device and at a transfer location delivered to an infeed location of the associated infeed path or line. Thus, at each crossing there is present an intermediate store or buffer of products which, on the one hand, renders possible a continuous conveyance of the product stream and, on the other hand, affords a continuous mode of operation of the processing stations.

Abstract: Axis correction or machine characteristic data is stored (108) in memory (110) within a control or measurement processor (36) of a CMM (10) (FIGURE 8). The axis correction data includes error data representing 21 different geometry errors (FIGURES 4A through 4C) of the CMM. As position information is required, the measurement processor captures the actual position signal from each machine axis sensor and uses this position signal to locate (112) a set of the axis correction data which describes the machine characteristics at that position. The measurement processor then mathematically combines (114) (FIGURE 9) the position signal with the subset of axis correction data to obtain a corrected position signal having a corrected set of coordinate values which describe the probe position in a true Cartesian coordinate system.

Abstract: This invention relates to a gear error measuring method and a measuring machine thereof through meshing and separating. The error is measured and taken during the meshing engagement of a specific master gear (49) with the measured gear (48). As the specific master gear (49) with its teeth arranged according to a specific rule and a device for fixing the unified starting position on the machine are adopted, various individual errors, composite errors, three-dimensional flank form error graphs, integrated error graphs and contact morphological graphs can be maesured and obtained in a measuring cycle, furthermore, the interrelation­ship among different individual errors and between the individual error and the composite error can be shown in the measuring result. This inventions is especially applicable to the error measurement of bevel gears and hypoid gears where different errors will hardly be measured by the exising measuring method at present.

Abstract: An impurity doping method for introducing impurity atoms contained in a photoresist layer into a semiconductor substrate is disclosed. The method includes fabricating steps for forming the photoresist layer containing impurity material on a surface of the substrate, for patterning the photoresist layer, for ashing the photoresist layer by exposing the photoresist layer to oxidising activated reaction gas such as ozone gas or oxygen reactive neutral species generated in a plasma generating apparatus of downstream type, leaving impurity atoms on the substrate, and for raising the substrate temperature to diffuse impurity atoms into the substrate to form a doped region therein. Damage to the semiconductor substrate caused by ion bombardment is thus avoided.

Abstract: The process consists in automatically fixing a threshold for detecting radio signals. This threshold is fixed as a function of a real-time estimate of the average value of the atmospheric noise power. The value of the noise is estimated by taking (5) noise and/or useful-signal samples which are applied to the input of the receiver, by distinguishing (6) the noise samples from the useful-signal samples and by calculating (7) an average value of the noise samples over a specified number N of samples. The detection threshold is then determined by the probability for which the instantaneous amplitude of the noise present at a given instant at the input of the receiver does not exceed by a specified number of decibels the average value of the calculated noise samples. Application: radio surveillance receivers. <IMAGE>

Abstract: Appareil et procédé de distribution de matériaux fluides, selon lesquels le fluide est déchargé par un ajutage (29) à un débit commandé par une soupape de dosage (27) ayant un siège (34) et une tige (32) mobile par rapport au siège pour moduler l'écoulement. Un servo-actuateur (20) connecté dans une boucle de commande de réaction est utilisé pour positionner la tige (32) de la soupape par rapport à son siège (34) en fonction d'un signal de commande (246). Le signal de commande est dérivé en fonction de la différence entre un signal d'entraînement (222) représentant un débit désiré et la somme d'une paire de signaux de réaction (211, 120a). Un signal de réaction (211) représente le débit réel tandis que l'autre signal de réaction (120a) est en corrélation à la fois avec la vitesse relative et la position de la tige (32) par rapport au siège (34). Le signal de vitesse (120a) dépendant de la position est généré par un transducteur (119) comprenant un aimant (150) et une bobine (134) influençable par le champ de l'aimant (150) lorsque l'aimant (150) et la bobine (134) se déplacent l'un par rapport à l'autre. Pour toute vitesse donnée, l'intensité du signal de vitesse dépendant de la position (120a) est plus grande lorsque la tige et le siège sont proches l'un de l'autre que lorsqu'ils sont plus éloignés l'un de l'autre de sorte que, au fur et à mesure que la soupape se ferme, la quantité de réaction augmente.
