摘要:
The present invention discloses a method for producing plastic optical member comprising a core region and a clad region. The method comprises carrying out polymerization of a polymerizable monomer, thereby obtaining an area corresponding to the core region. The Polymerization is carried out in the presence of a polymerization initiator having a ten-hour, half-life decomposition temperature T h (°C) (T b - 20 ≦ T h ; T b is the boiling point (°C) of the polymerizable monomer), at an initial polymerization temperature T 1 (°C) (T b -10 ≦ T 1 ≦ T g ; T g is the glass transition point (°C) of the polymer made of the polymerizable monomer) , for a period which is equal to or longer than 10% of the half-life of the polymerization initiator at T 1 ; and further carried out at an elevated temperature T 2 (°C) (T g ≦ T 2 and T 1 2 ) .

An auxiliary scanning feed mechanism (52) has a pair of curved feed guides (58a, 58b) for guiding a stimulable phosphor sheet (IP) along a curved feed path (P), and first and second roller pairs (60, 62) rotatable in synchronism with each other for gripping and feeding the stimulable phosphor sheet (IP) along the curved feed path (P). The first and second roller pairs (60, 62) have respective first and second drive rollers (64, 66) disposed inwardly of respective curved sections of the curved feed guides (58a, 58b) and respective first and second driven rollers (68, 70).
摘要:
The method of making a tubular member having a continuous and uninterrupted cured elastomeric resin coating on an outer surface of the member includes forming a continuous uninterrupted tubular layer of uncured elastomeric resin and drawing the resin layer against the surface of the tubular member to be coated by applying suction between the resin layer and the surface of the tubular member so that the resin adheres to the surface of the tubular member. The elastomeric resin may then be cured to produce the final product. Apparatus for carrying out the process is disclosed and includes, in sequence, a coating zone including a sub-atmospheric chamber, a heating zone and a feed mechanism for advancing the tubular member relative to the coating and heating zones. A method is also disclosed for molding a distal end cap on an open end of a length of a preformed tubular sleeve member that may be used for prosthetic applications. A process is also disclosed for molding a sleeve member having prosthetic applications using male and female die elements used to distribute uncured elastomer resin as a layer on a tubular elasticized fabric sleeve element.

A magnetic tape cassette storage case (1) comprising a storage section (3) for storing a magnetic tape cassette (81), a lid section (5) for covering the storage section (3), and a connecting section (7) for connecting the storage section (3) and the lid section (5) so as to enable the open-and-closed motion; in which the storage section (3) and the lid section (5) comprise plate portion (11, 21) and sidewall portions (13, 23) provided along the outer peripheries of the flat portions (11, 21) respectively. A notch (26b) having at least the height of the sidewall portion (13) provided on the storage section (3) is formed on the inner side of the end of the sidewall portion (23) closer to the connecting section (7) of the lid section (5).
摘要:
An electrophoresis apparatus for the simultaneous electrophoretic separation of a plurality of component mixtures comprises, includes a disposable tray defining a plurality of substantially parallel troughs. Each trough is shaped to retain an elongate strip of isoelectric focusing medium and sufficient liquid to immerse the elongate strip. A frame is provided to retain the tray in a substantially horizontal position. A pair of support members are rotatably mounted to the frame such that when the tray is retained therein each support member spans the plurality of troughs, with each support member supporting a plurality of electrodes arranged such that one electrode from each support member is aligned with each of the plurality of troughs. The support member is rotatable between a first position in which all electrodes thereon extend into the troughs and a second position in which all electrodes thereon are clear of the troughs.
摘要:
Un système capteur optique, utilisé notamment pour détecter des rayonnements diffus de faible intensité, comme c'est le cas lors du contrôle de billets de banque pourvus de marques luminescentes, comprend, dans un mode préféré de réalisation, un stylo conique à fibre optique et des éléments optiques de traitement. On peut détecter, avec l'extrémité à section transversale étroite du stylo à fibre optique, le rayonnement en provenance de l'objet à mesurer dans un grand angle solide. Ce rayonnement sort du stylo à fibre optique, étant donné la modification de sa section transversale, sous un angle essentiellement plus réduit adapté à l'angle d'ouverture des éléments optiques en aval.
