Abstract: Support d'enregistrement sous forme de disque optique comprenant un substrat comportant des marques de temporisation et d'adresse et une couche d'enregistrement de données fixe par rapport au substrat et possédant une surface d'enregistrement distincte, sur le plan optique, des marques d'adresse et de temporisation. Ce support d'enregistrement comprend, de préférence, également un film semi-transparent placé entre le substrat et la couche d'enregistrement et conçu pour réfléchir une première longueur d'onde de lumière transmise à travers le substrat et pour transmettre à la couche d'enregistrement une deuxième longueur d'onde de lumière différente de la première longueur d'onde. Les données d'utilisateur sont ensuite enregistrées sur le disque optique, ce qui consiste à mettre en application un premier faisceau lumineux à la première longueur d'onde et un deuxième faisceau lumineux à la deuxième longueur d'onde, à aligner les faisceaux en fonction des informations d'adresse et de temporisation récupérées depuis les faisceaux réfléchis du premier et du deuxième faisceaux lumineux, puis à enregistrer les données d'utilisateur dans la couche d'enregistrement d'après les informations récupérées d'adresse et de temporisation. Dans un autre mode de réalisation, le disque optique comporte un film placé entre le substrat et la couche d'enregistrement et conçu pour positionner la surface d'enregistrement à une longueur focale d'enregistrement et les marques à une longueur focale de substrat différente de la longueur focale d'enregistrement. Les données d'utilisateur sont ensuite enregistrées sur le disque optique par concentration d'un premier faisceau lumineux à la longueur focale du substrat et d'un deuxième faisceau lumineux à la longueur focale d'enregistrement, par alignement des faisceaux en fonction des informations d'adresse et de temporisation récupérées depuis les faisceaux réfléchis du premier et du deuxième faisceaux lumineux, puis par enregistrement des données d'utilisateur dans la couche d'enregistrement d'après les informations récupérées d'adresse et de temporisation.

Title: Biaxially oriented polyamide film and method for producing the same
Inventor: MIZUTANI TOMOJI
IPC: B29C55/12
Filed: 1989-11-21
Abstract: Heat setting by the conventional tentering method provides polyamide film which is anisotropic in heat shrinkage.  Therefore, only the central part of the film can be used for applications which need a low degree of anisotropy.   The present invention provides an improved method of heat-setting biaxially oriented polyamide film in flat form.  Said method is characterized in that biaxially oriented polyamide film, with the edges thereof gripped, is heated to an adequate temperature after preheating the polyamide film when it is desired, which is 10-40°C lower than the melting point of the film, by bringing it into close contact with the surface of a heating body, and immediately thereafter the film is cooled to a temperature at which the film does not deform easily.    The present invention also provides biaxially oriented polyamide film which has a uniform heat shrinkage across the entire width of the film.  The shrinkage by hot water at 100°C is smaller than 5.0 % in all the directions in the plane, and the anisotropy H (%) in hot water shrinkage which is calculated from the formula below is less than 30%, preferably less than 20%, across the entire width of the film.     (see fig. I) (where S45 and S135 respectively denote the shrinkage (by hot water at 100°C) in the directions deviated leftward 45° and 135° from the machine direction.)

Abstract: ABSTRACT OF THE DISCLOSURE      A ferroelectric liquid crystal device has a first state (TX1) of maximum transmission, a second state (TX2) of minimum transmission and a value of voltage pulse width (tg) and voltage pulse height (VS) sufficient for a switching pulse to switch the cell from the first state (TX1) to the second state (TX2) or vice verse.  A method of controlling the transmission of electromagnetic radiation through the ferroelectric liquid crystal device comprises the step of applying, for a time period greater than said value of pulse width (tS), a plurality of consecutive controlling pulses of one polarity.  Each controlling pulse is itself of insufficient pulse height and pulse width to switch the cell from the first state (TX1) to the second state (T12) or vice versa.

Abstract: "VOLATILE LIQUID RECOVERY PROCESS"                  ABSTRACT OF THE DISCLOSURE The feedstock comprises agglomerates of oil sand containing water and light hydrocarbon solvent.   The feedstock is introduced into a downwardly inclined kiln having an externally heated pre-heat section.  Here the feedstock is heated to about 100°C as it is advanced through the section.  The heated feedstock then is advanced through an insulated stripping section of the kiln, in the course of which  low  pressure  saturated  steam  is  flowed countercurrently.   The temperature of the feedstock is maintained at about 100°C in the stripping section.  The solvent is vaporized and recovered from the kiln. Vaporization of water is suppressed by the steam flow.

Title: Heat-treated steel with improved mechanical and technological properties
Inventor: SCHMITT WOLFGANG
IPC: C21D1/19
Filed: 1990-08-28
Abstract: ABSTRACT OF THE DISCLOSURE            A heat-treated steel product has improved mechanical and physical properties, in particular in the dimensional range of steel wire bar and light steel sections.  The steel can be used with advantage as a construction steel.  The mechanical and technological properties of the steel are improved in such a way that in the case of concrete-reinforcing steels an advantageous intermediate structure for subsequent thermal hardening is achieved.  In the case of purely ferritic-perlitic construction steels, a favourable final structure is selected.  These structural states are achieved in direct combination with the thermal hardening or simply through the heat treating of the steel in the rolling process. Throughout its cross section the steel possesses heterogeneous structural and strength properties, with only the boundary zone being normalized.  In the case of a construction steel, it consists of a non-normalized, ferritic-perlitic core region surrounded by a normalized, ferritic-perlitic boundary zone.  On the other hand, in the case of a as a thermally hardened concrete-reinforcing steel, the steel consists of a non-normalized, ferritic-perlitic core region surrounded by a normalized and subsequently tempered boundary zone.
