Abstract: The seat belt retractor comprises a frame (12); a drum (D) rotatably supported by the frame (12) to wind up the seat belt (10) therearound; an emergency lock mechanism (30); and a seat belt take-up mechanism (20) including, in particular a coiled spring (21) for applying a take-up force to the seat belt (10). Since a coiled spring (21) is used to apply a take-up force to the seat belt (10), the take-up torque can be simply determined by changing the diameter of the coiled spring and the number of turns, without increasing the outer diameter of the coiled spring, thus improving the binding feeling of the seat belt (10) to the driver (not illustrated). Further, the coiled spring (21) is excellent in durability, low in cost and small in size as compared with the conventional flat spiral spring.

Abstract: The present invention relates to a steering handle grip (G) to be attached to the steering handle bar (36) of a bicycle, motorcycle or other ground vehicle, including a grip body (37) made from an elastically deformable material such as synthetic resin or rubber and having a thickness and length such that it can be held by one hand, and a pair of operator's hand stopping flanges (45, 46) of large diameter bulging continuously and integrally from the longitudinal opposite ends of the grip body, the handle grip being characterized in that: 
the grip body (37) is egg-shaped (specially elliptic) in cross-section, having opposed front and rear arcuate surfaces (37f, 37r) positioned on the major axis (Y-Y), the front arcuate surface (37f) being contacted by the second through fifth fingers of the operator's hand, the rear arcuate surface (37r) being contacted by the palm, 
an attaching port (38) for attachment to the handle bar, the attaching port opening at an eccentric position deviated toward the rear arcuate surface (47r) along the major axis of the grip body, 
wherein the thickness (T1) of the front region defined between the inner wall surface of the attaching port and the front arcuate surface is greater than the respective thicknesses (T2, T3, T4) of the remaining regions, and 
wherein the thickened front region is formed with a   plurality of dot-like through-holes (39) substantially orthogonal to the major axis of the grip body. 
     Thus, when the operator steers the ground vehicle, his hands intimately fit the steering handle grips, whereby the handle grips can be held stably and firmly in hands and even subtle movements of the fingers can be effectively transmitted to the handle grips to orient the vehicle as desired.

Abstract: The method provides for successive frames of a small image to be inserted into a main image consisting of successive frames to be written alternately frame-by-frame into one of two storage areas of a storage device, for a decision signal, which specifies from which of the two storage areas a stored frame of the small image is to be read, to be generated in each case at the beginning of the displaying of a main image and thus for the small image to be inserted into the main image without overlapping of images. To achieve interference-free insertion of the small image, line interlace inversions in the image to be inserted can also be avoided. In addition, the method according to the invention provides for picture-in-picture insertion at twice the frame repetition rate or, respectively, twice the field repetition rate which results in good reduction of flickering in the small image to be inserted. <IMAGE>

Abstract: The invention relates to microcapsules with a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, and to processes for the manufacture of the said microcapsules. 
     According to the invention, the microcapsules comprise a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, the propor­tion of polyholosides, for example glycosaminoglycans, relative to the atelocollagen preferably being between 18 and 50% by weight. These microcapsules can be manufac­tured either by a process involving interfacial cross­linking or by the extrusion of a laminar flow which is broken up by vibrations into individual droplets, which fall into a crosslinking bath. 
     These microcapsules are biocompatible by virtue of   the presence of atelocollagen, which has most of the advantageous properties of collagen, namely a very low antigenicity and a perfect biodegradability. They are therefore particularly suitable for the manufacture of cosmetic, pharmaceutical or food compositions.

Abstract: Dans ce raccord à bride résistant à la torsion, la résistance torsionnelle et le centrage des deux moitiés du raccord à bride (1, 10) sont assurés selon un procédé connu, à l'aide de vis calibrées (21) dont les têtes (22) peuvent être dotées d'une région extérieurement conique (23A). Les vis calibrées (21) sont dans une large mesure libres de charges axiales, ces dernières étant supportées par un raccord fileté séparé (15, 16 et 21C, 21D, respectivement). Cette structure est particulièrement avantageuse pour les boîtes planétaires où il s'agit d'assurer une grande précision même avec des charges alternantes de couple et des ensembles de faibles dimensions. L'interstice axial (26) entre porte-couronne (10) et axe de satellite (5) est maintenu aussi petit que possible grâce au fait qu'on utilise des vis à douille (24). La bride extérieure (10) qui sert de porte-couronne est utilisée pour régler un palier (11). Selon une variante, un raccord fileté (15, 16) servant à la fixation axiale empêche cette bride de se dévisser grâce à des vis calibrées (21) dont les alésages filetés correspondants coupent à moitié à la fois le filetage femelle et le filetage mâle (15, 16). Grâce à des vis calibrées (21) dotées de têtes extérieurement coniques (23A) et de douilles (25) ou élargissements d'alésages coniques correspondants, on évite les erreurs de centrage et l'apparition, sur la durée, de jeux. Une autre variante permet une fixation axiale séparée grâce à des vis filetées simples (21C) agencées à l'intérieur de la bride (1) et dont les têtes sont noyées dans la bride posée (10), avec un jeu radial.
