Title: Optical disc player system
Inventor: LEHUREAU JEAN-CLAUDE
IPC: G11B7/13
Filed: 1992-06-30
Abstract: The invention relates to systems for playing information stored in optical form (optical disks). According to the invention, use is made of the fact that the light from the source of illumination (L) of the optical disk (D) is a coherent source, in order to form a hologram on a photodetector array (BCCD). This hologram is the compounding of the unmodulated incident beam from the source with the beam reflected by the disk, modulated by the information to be played. Signal processing by Fourier transformation, shifting in the plane of spatial frequencies, inverse Fourier transformation, makes it possible to get back to the information written on the disk. The detection of the information can be much more thorough than in the case of the conventional playing of optical disks, since it involves not only the global modulation of light energy from the laser beam, but also phase modulation. This makes it possible to increase the information storage density, to reduce the precision of the optical and mechanical systems of the player, and to process electronic signals in order to correct defects in optical systems and focusing defects. <IMAGE>

Abstract: A method of manufacturing high-strength, cold-rolled steel sheet excellent in formability. When increasing the strength of extra low-carbon steel as a base material including Nb or a combination of Ti and Nb by adding solid-solution strengthening element thereto, quantities of P and Si to be added which have been used in quantities are decreased whereas Mn and Cr are liberally added. Thus, the yield strength is prevented from increasing and the strength can be increased, whereby a high strength cold rolled steel sheet excellent in surface formability and in resistance to denting can be manufactured.

Abstract: Le flux de particules de métal en fusion du dispositif de diffusion est défléchi d'un bord à l'autre par un gaz sortant de deux buses disposées de manière diamétralement opposées par rapport au flux. Le gaz est acheminé jusqu'aux deux ensembles de buses (13) de manière alternative sous l'effet d'une vanne rotative (19) pourvue d'un stator (18) et d'un rotor cylindrique (24). Le rotor comporte deux rainures circonférentielles, le profil de ces rainures variant selon un schéma déterminé et chacune de ces rainures servant à assurer et à couper la communication entre un orifice d'admission (21) du gaz sous pression et un orifice de sortie (23) se trouvant dans le même alignement circulaire que l'orifice d'admission et débouchant sur un orifice correspondant avec l'un des ensembles de buses. Les sections de passage des orifices d'admission et de sortie sont supérieures à la section de passage maximale de la rainure, de telle sorte que la quantité de gaz atteignant les buses à tout moment est déterminée par la surface efficace instantanée de la rainure (26). La limitation de la quantité de gaz libérée par les buses correspondant à une déflexion maximale de diffusion des particules de métal est toutefois déterminée par le total des sections de passage des buses de l'ensemble. Toute augmentation de la quantité de gaz libérée par les buses accroît la déflexion du flux de particules métalliques.

Abstract: An FET mixer circuit having a stable input impedance uses two tandem-connected GaAs MESFET's (1, 2) of pulse doped structure instead of a conventional MESFET or a HEMT, as an active device. A gate biasing point for the FET (1) is set around a pinch-off point of a mutual conductance, and a gate biasing point for the FET (2) is set in a region which assures non-change of a mutual conductance with respect to the increase of a gate voltage. Thus, a mixer circuit having a good isolation characteristic for an RF signal and a local oscillation signal and exhibiting substantially no change in the input impedance is attained.

Abstract: A technique for improving the tone and color reproduction of print and slide images which are photographed onto color negative film, scanned by a Photo CD negative scanner and transferred onto Photo CD discs is disclosed. The technique incorporates a calibration method for (1) producing color negatives (or slides) using normal scanner calibration targets, (2) producing controlled prints from the negatives, (3) re-photographing the prints (or slides) onto a second color negative film, and (4) performing the normal scanner calibration using this second "cascaded" film. The calibration step not only "compensates for" the second color negative film (as is the case when calibrating for "normal" film exposed from the original scenes) but also "compensates for" the first negative film "print through" (or slide) characteristics. This means that the image data recorded on the Photo CD disc will more closely resemble the data which would be produced if the original scene had been photographed on color negative film and scanned directly.

Abstract: A marking area whose optical reflection property differs from that of a non-marking area is formed in a portion of a surface of an electrically conductive substrate. Assuming that the average line of a vertical section of the non-marking area cut across the border line with the marking area is M₀ and the average line of a vertical section of the marking area cut across the border line is N₀ and that straight lines touching the average lines M₀ and N₀ at the intersection of M₀ and N₀ are tangent lines M₁ and N₁, respectively, the acute angle ϑ between M₁ and N₁ is within the range of 0° ≦ ϑ ≦ 30°. Setting the angle ϑ within the range enables a photoconductive layer of a uniform characteristic to be laminated on the electrically conductive substrate even when the marking area is formed on the surface of the substrate. With this arrangement, since information for optimizing the image quality of copies is obtained from the same location of a photoreceptor drum with reference to the marking area, a photoreceptor for electrophotography always produces copies of stable image quality.

Abstract: Disclosed is a variable gain amplifier. A variable current source (6) is provided between the base of an emitter-grounded transistor (1) and the ground, so that the distribution of the base bias current of the transistor (1) is controlled by controlling a change in the current of the variable current source (6), thereby controlling the amplifier gain. As the emitter of the transistor (1) can be directly grounded, thus eliminating the need for a bypass capacitor and facilitating integration of the amplifier. As the base current of the transistor (1) is controlled, the control power can be made very low. Further, a single stage of a transistor (61) is provided between the power source and the ground, the voltage of the power source can be reduced further. It is therefore possible to provide a variable gain amplifier, which accomplishes low power consumption, is operable on a low voltage, is easy to be integrated, and is suitable for use as a high-frequency power amplifier of 1 to 2 GHz in a battery-driven portable electronic device, such as a mobile telephone.
