Date Jul. 13, 1995A process for producing threads by metal cutting when a more or less gradual change of the thread profile is desired in at least one of its sections. When producing a thread by turning, by milling or by turning and milling, the thread is cut in at least two successive operations with at least two different thread pitches and/or an offset value or a continuously changing pitch. The process is preferred for making possible a gradual change in the height and shape of the teeth or, as the case may be, the design of the thread bottom of a self-cutting thread to be progressively adapted to the curved outer profile of an artificial hip-joint socket.

Filed: 1994-04-08
Abstract: In a process for connecting the ends (22) of a first plastic strip (6) with the start (21) of a second plastic strip (5): (i) the conveyer is stopped; (ii) the respective ends (21, 22) of the strips (5, 6) are overlapped; (iii) the ends (21, 22) are welded together across a lateral area under heat and pressure until the thickness of a single plastic strip (5, 6) is achieved; and (iv) both lose ends (21, 22) are torn away.  Also claimed is the process appts. including (i) two movable carriers (1, 1') as wide as the strips (5, 6) and at a distance from each other; and (ii) a welding bar (8, 8') held in a groove (2, 2') extending laterally across each carrier (1, 1') and projecting from it.  Pref. welding is effected with welding bars (8, 8'). The upper, second plastic strip (5) undergoes high compression in a first area than the first plastic strip (6) below it.

Inventor: ISHIDA HIROSHI
IPC: B41J29/10
Filed: 1994-10-04
Abstract: Noise from a selective print head 17 is reduced by so arranging an edge 18a of the paper exit slot of the machine housing (with respect to both the paper discharge rollers 31, 32 and an external paper tray 19) that the paper bears against said edge, thereby utilizing the paper itself to acoustically isolate the print head from the exterior of the casing. To ensure satisfactory transport of the paper while preventing "set-off" of ink from the printed paper, the drive roller (31) of said pair of discharge rollers (31, 32) is made of high friction material (rubber) and the idler roller (32) of the pair is made of ink resistant material (synthetic resin), and the leading end of a sheet (P) is guided so as to be abutted against the drive roller (31) earlier than the driven roller (32). The upper discharge roller 31 is resiliently mounted to an openable part of the machine housing, and the lower roller 32 is mounted on a resiliently pivotable carrier 34 which is biassed to engage a drive wheel 33 against the platen. <IMAGE>

Abstract: Afin d'éviter ou d'augmenter sélectivement l'adsorption ou l'adhésion de particules sur des matériaux souples ou rigides, on applique des bandes d'électrodes planaires (22; 42, 44; 52) extrêmement miniaturisées (de l'ordre sous-micrométrique) sur une surface (21; 41; 51). Lorsque l'on applique des trains d'impulsions de haute fréquence sur ces bandes d'électrodes, des ondes électriques de surface progressives ou stationnaires sont générées. Les électrodes elles-mêmes sont associées à des matériaux isolants diélectriques ou à biocompatibilité contrôlée (23; 43, 45; 53), et sont ainsi entièrement ou partiellement recouvertes. Le type d'amorçage électrique, de même que les propriétés des couches de surface qui recouvrent les électrodes, déterminent les propriétés d'adhésion de la surface de manière largement indépendante du matériau de base utilisé. Le mouvement des particules est influencé avec ménagement. On peut ainsi pour la première fois influencer des particules dans des solutions nutritives hautement physiologiques.
