Abstract: In an electric power steering device of the type wherein an input member connected to an electric motor and an output shaft including an output member connected to a steering wheel are connected via a plurality of sets of friction clutch mechanisms for transmitting an auxiliary torque from the electric motor to the output shaft, the output member is displaceable in a radial direction relative to the input member. In response to rotation of position control members of the friction clutch mechanisms, one of the friction clutch mechanisms sets is disengaged whereupon a force or pressure exerted from the locking members of the other friction clutch mechanism sets to the output member forces the output member to move in the radial direction relative to the input member. With this movement of the output member, a frictional engagement force acting between the locking members and the input and output members is reduced.      Thus, the friction clutch mechanisms can be readily disengaged by a force which is much smaller than the force required to disengage all the friction clutch mechanisms at one time.

Title: Dispositif de compensation de desalignement axial et spatial entre un composant rotatif et un systeme de rotation
Inventor: EDWARDS STANLEY H JR
IPC: H01H3/32
Filed: 1996-10-03
Granted: 2005-03-22
Abstract: La présente invention concerne un arbre d'entraînement assurant une compensation du désalignement axial et spatial entre un composant rotatif monté à l'intérieur d'un boîtier et un système de rotation placé d'une manière générale à l'extérieur du boîtier. L'arbre d'entraînement comporte une première extrémité dont les dimensions lui permettent de coulisser dans une partie réceptrice du système de rotation, de telle sorte que l'arbre soit maintenu dans une position angulaire fixe par rapport au système de rotation. L'arbre peut être glissé axialement par rapport au système de rotation de façon à compenser le désalignement axial entre le composant rotatif et le système de rotation. L'arbre d'entraînement présente également une seconde extrémité formée de manière à venir en prise avec le composant rotatif, de telle sorte qu'une rotation du système de rotation produise une rotation correspondante du composant rotatif. Un dispositif de compensation spatiale est par ailleurs intégralement incorporé dans l'arbre, entre ses première et seconde extrémités. Ce dispositif compense le désalignement spatial entre l'axe du composant rotatif et l'axe du système de rotation. On obtient cet effet en créant un angle de correction entre les première et seconde extrémités, ce qui permet à l'arbre de tourner autour de son axe tout en maintenant l'angle de correction.

Abstract: Kraft pulp of increased strength and bleachability may be produced with deceased consumption of effective alkali, and at a lower H factor, by keeping the dissolved organic material (DOM) concentration low substantially through the entire kraft cook, including by extracting high DOM liquid from at least one part of a continuous digester and replacing it with much lower level DOM liquid. Existing pulp mills having two-vessel hydraulic, one-vessel hydraulic, or other systems may be retrofit to provide for extractions and additions of low DOM dilution liquor (including substantially DOM-free white liquor). Also, commercial size batch digesters (8 tons per day of pulp or more) can be operated with low DOM liquor to produce increased strength pulp. Using dilution with low DOM liquor also results in reduced H factor and effective alkali consumption, and increased bleachability.

Abstract: The invention is a method for selecting, producing, and delivering a finished mail piece. The method includes the step of selecting, at an initiating node, a set of parameters which together comprise a mail piece to be produced at a remote location. The selection is made from a series of menus within a program resident within a data processing system. Among the parameters which can be selected or determined are the destination address, type of delivery service to be used, and a choice of the media stock upon which a selected text can be printed. Additionally, a choice of language for the text can be made, and an account number for debiting the cost of the transaction may be entered. The selected parameters are transmitted to a data center which reads the destination address and then determines the most appropriate destination node. It is possible for the data center to be co-located with the initiating node or, to be the destination node. The data center, which maintains all data with respect to a particular transaction, will transmit the selected parameters to the destination node. Upon receipt of the data, the destination node prints the selected text upon a media which is inserted into an envelope with the destination address printed upon the envelope. The envelope is then franked in proper local currency and delivered to a local postal stream for final delivery to the destination address.

Abstract: An pulse arc welding apparatus feeds a consumable electrode with a constant rate, and arc-welds by applying a welding current constituted of a pulse current of a constant voltage characteristic and a base current of a constant current characteristic between the consumable electrode and a workpiece.  A pulse current control circuit outputs a pulse current command value, based on a difference signal between a pulse voltage detector and a pulse voltage setting device.  A pulse frequency control circuit outputs a pulse frequency command value, based on a difference signal between a pulse current detector and a pulse current setting device.  Setting devices which output a pulse current upper limit value or lower limit value are provided.  A pulse current comparison and adjustment circuit inputs a pulse current command value and a pulse current upper limit value or a pulse current lower limit value, and outputs the pulse current upper limit value, when the pulse current command value is larger than an upper limit value of a pulse current, and/or outputs the pulse current lower value when the pulse current command value is less than a lower limit value of the pulse current, and outputs the pulse current command value in a case except the above. The pulse frequency correction circuit outputs a frequency correction value f~ to the pulse frequency control circuit, such that when the pulse current upper limit value or lower limit value is selected continuously in a predetermined number of times at the pulse current comparison and adjustment circuit, the pulse frequency is increased/decreased by a predetermined value .DELTA.-f by .DELTA.-f in accordance with the selected number of times.

Abstract: Après avoir placé l'aiguille sur le support d'aiguille (210) en position de chargement, on tourne le support vers le bas pour le mettre en position de découpage. Dans cette position, deux lames de contact opposées (220, 230) pincent l'aiguille, qui relie électriquement les bornes positive et négative d'un accumulateur. Le courant traverse les lames (220, 230) et l'aiguille, et fait fondre cette dernière. Si l'on fait tourner un peu plus le support d'aiguille (210), les lames cisaillent l'aiguille, dont la partie cisaillée tombe dans un compartiment à déchets. Quand on enlève la seringue du support d'aiguilles (210), celui-ci tourne vers le haut et revient en position de chargement. Un ressort de torsion (236) applique une pression constante sur une lame de contact (230), de façon à maintenir le support d'aiguille (210) dans la position de chargement en l'absence de toute pression vers le bas.
