  • Thermal head printer
    Patent number: 4963885
    Abstract: A thermal print head includes a plurality, e.g., three of delay shift registers operating by a clock-controlled shift scan to receive dot print signals from a dot print signal generating circuit. The delay registers have a number of addresses corresponding to the number of dot print elements in the printer head. The dot print signals from the delay shift registers are applied to an OR gate connected to the print registers for the dot print elements. With this construction, the shift scan cycle t is set so that t=T (n+1), where T is the least print cycle under normal printing conditions and n is the number of delay shift registers. Printing is effected with a high resolving power to restrain any decline in coloring properties using interpolation dot print signals derived from real time print signals by the delay shift registers.

  • High strength laminate with barrier layer
    Patent number: 4908253
    Abstract: A high-strength laminate comprising generally weakly adhered biaxially oriented films, each formed of a blend which exhibits a distinct fibrous morphology with the fibres forming a distinct unidirectional grain when measured on a macro-scale but with the fibre-portions strongly deflected from this direction as seen on a micro-scale and with the unidirectional grain in at least two of the films criss-crossing each other. Producing this laminate by melt attenuating the blend(s) while extruding the latter to films, cross-laminating the layers before or after solidification while they are still in molecularly unoriented state--except for the weak orientation produced by the melt-attenuation--and finally strongly biaxially orienting the laminate by stretching in several steps, whereby the stretching is generally uniaxial during each step.
