Patent EP-0310681-A1 (EP)
Inventor: YAMAMOTO YOHZOH
IPC: C08L63/10
Filed: 1988-04-15
Abstract: Composition pour amortisseurs de vibrations, comprenant une résine de polyol (A), une résine d'hydrocarbure (B) présentant un point de ramollissement allant jusqu'à 25°C si on le mesure par le procédé de Durran, et un agent de polymérisation (C). On produit cette résine de polyol (A) en faisant réagir une résine de polyol essentiellement dépourvue d'époxy (1) obtenue par réaction entre une résine époxyde au biphénol spécifique (a) et une composé d'hydrogène actif (b) possédant un atome d'hydrogène réactif en présence d'un groupe époxy avec un acide gras monobasique (2). Cette composition pour amortisseurs de vibrations est constituée de la résine de polyol spécifiée (A), d'une résine d'hydrocarbures (B) en tant que plastifiant et d'un agent polymérisation (C). Un amortisseur de vibrations obtenu par la polymérisation de cette composition possède environ la même durée de vie que celle d'amortisseurs conventionnels similaires à base d'une résine époxy, et présente d'excellentes propriétés d'amortissement de vibrations, non seulement au voisinage du point de transition de phase, mais dans une grande plage de témperatures d'utilisation.

Title: Apparatus and method for driving a ferroelectric liquid crystal device
Inventor: BOWRY CAROLYN
IPC: G02F1/133
Filed: 1988-08-12
Abstract: In a method of driving a matrix of ferroelectric liquid crystal devices 
in a TDM mode, each strobing signal comprises first and second pulses 
(29, 21) of opposite polarities and of different amplitude, together with a 
dc voltage (26) which is applied from the end of the second pulse to the be­
ginning of the first pulse of the next strobing signal on the same strobe line 
to cancel the dc level which would be caused by the unequal pulses. Data 
ON signals applied selectively to data lines of the matrix comprise two 
consecutive pulses (22, 23) of opposite polarities. Data OFF signals (24, 25) 
may be the inverse of the data ON signals or may comprise a constant dc 
level. The combination of the two pulses with a dc level to form each strob­
ing signal means that only two strobe pulse time slots per frame are re­
quired for addressing each strobe line, as compared with the conventional 
systems in which four time slots per frame are required.

Filed: 1988-07-27
Abstract: Apparatus for continuous production of flake ice comprises one or more refrigerated discs (20) mounted on a hollow shaft (18, 21, 71). Each disc (20) rotates in the vertical plane and includes a plurality of narrow internal channels (30) which extend substantially over all of the operative portion of the disc (20) and are of substantially equal length. The disc(s) (20) forms(s) the evaporator of a refrigeration circuit, and an evaporative refrigerant is circulated to the channels (30) in each disc (20) via the hollow shaft (18, 21, 71). During each cycle, water is applied to both external flat surfaces of each disc (20) at a first angular location and the film of water which adheres thereto freezes as the disc (20) rotates. The ice sheet so formed is removed from both sides of the disc (20) at a second angular location by scraper blades (40, 75).

Abstract: Afin de générer dans un gyroscope à fibre optique une modulation de phase des rayons de lumière circulant en sens inverse dans un enroulement capteur en fibres optiques, une tension de modulation est appliquée à un modulateur optique de phase. Un signal concernant la vitesse de rotation est obtenu par redressement sensible à la phase à partir des rayons de lumière superposés. Afin d'optimiser la modulation de phase, des communications dérivent par filtrage et par redressement sensible à la phase un signal de réglage à partir du signal de sortie du gyroscope à fibre optique, lequel contient, dans les cas où il faut effectuer un réglage, outre le signal concernant la vitesse de rotation J1 (2PSI) sin DELTAphi du gyroscope (7), un signal partiel concernant une fréquence auxiliaire de modulation (f2) ou un multiple impair de celle-ci. Le signal de réglage influence la tension de modulation du modulateur optique de phase de façon à ramener au moins approximativement à zéro les signaux partiels de fréquence (f2) ou un multiple impair de ceux-ci.
