Abstract: A windscreen (1) for automobile vehicles is provided with a reflecting device (6) for displaying information or optical signals in the field of visibility of the windscreen (1). According to the invention, the reflecting device (6) is a hologram having the properties of a mirror. The angle of reflection  alpha  of the holographic mirror is different from the angle of reflection  beta  of the surface of the glass. In this way, the eye (8) of the observer does not receive rays R' reflected by the surface of the glass, but only rays R reflected by the holographic mirror. In the case of a curved windscreen, a hologram acting as a plane mirror is arranged on a curved support layer so as to correspond with the shape of the windscreen such that, even in the case of a curved windscreen, the reflected image of the information or of the optical signals is free of optical aberration.

Abstract: Data to be switched is preceded by a header containing routeing information for establishing a connection via a switch, and is accompanied by additional information which indicates the start of the header, in response to which a connection is established, and the end of the data, in response to which the connection is terminated. The switch is a non- saturating, non-blocking, full matrix time switch which uses the routeing information to establish a connection within one tdm frame, whereby connections for data of any type (including switch control information) and of arbitrary duration can be handled efficiently. An incoming channel can be connected to any free channel or to a specified outgoing channel of any output port, and contention resolution is provided for simultaneous requests for connection to a single outgoing channel. Interconnections among crosspoint nodes are reduced and simplified using token ring and systolic interconnection techniques.

Abstract: In a data processing system having an associated magnetic storage device, a controller is disclosed that permits storage capacity of the magnetic storage device to be substantially increased without altering either the data processing system control signals or the portion of the magnetic storage apparatus physically storing and/or retrieving the data signals on the magnetic media. The storage capacity is increased by using an encoding scheme that, although not substantially changing the density of flux reversals on the magnetic media, stores approximately twice the information. Apparatus is disclosed for improving the detection and decoding of the information stored on the magnetic media. The technique for increasing the information density, while particularly relevant to the magnetic hard disk systems used with personal computers because of the capability of increased information storage by altering only the magnetic hard disk controller, can also be used with other information storage systems such as optical storage systems.

Abstract: A multiple-disk player which detects a time period during which for the player operates in the non-playback mode after the playback start command is given and calculates a time period value on the basis of the difference between the current value of the time information datum read out of the disk and its preceding value; the detected non-playback mode time period is added to the playback time period to produce the total time period; and performs a fade-out operation for a music being played back when such total time period reaches a given allowable time period. 
     Consequently, it is possible to quickly and surely check the fade-out operations even before all the pieces of music to be played back are not actually played back.

Abstract: A corrugated paperboard, manufactured with a layer of plastic film approximately 1-3 mil thickness, is laminated to the single face liner of single face board in the double-backer. The board has good moisture vapor transmission (MVT) properties for packaging food and chemical products. The film is supplied in roll form and reeved over a dewrinkling roll device to smooth it, then fed onto the single face liner as the single face corrugated is fed into the nip of the double-backer. The lamination of the film is made by the residual heat from the paper and pressure of the double-backer belt in the drying section of the corrugator without adding adhesives or other compounds. The film is a thermoplastic co-extruded polymeric film, e.g. high density polyethylene (HDPE), polypropylene, PET, having a heat seal layer thereon of a copolymer of olefin with Alpha-Beta monoethylenically unsaturated monomer, e.g., ethylene acrylic acid (EAA). The film surface of the manufactured board may be optionally treated with Corona discharge or high velocity flame treatment to oxidize the surface to enhance adhesive bonding in later prepared cartons made from the board. The process is applicable to single wall or multiwall corrugated paperboard in making a vapor barrier product having good MVTR.
