  • Patent number: 10600378
    Abstract: A liquid-crystal driving device is formed by integrating: an external output terminal to which a source line of an LCD panel is exteriorly connected; a first driver which generates a first source signal having three or more gradations (for example, 256 gradations) and outputs the first source signal to the external output terminal; an abnormality detection unit (a logic unit and an output monitor unit) which detects an abnormality in the first source signal; and a second driver which, when an abnormality in the first source signal is detected, generates a second source signa) having two gradations and outputs the second source signal to the external output terminal. The LCD panel is driven in a predetermined polarity inversion drive system, and the abnormality detection unit, for example, monitors polarity inversion of the first source signal in a fly-back period and detects an abnormality in the first source signal.

  • Patent number: 4581003
    Abstract: A method for manufacturing a container for filling with juice or the like at a high temperature includes applying a container body to a mandrel having an outer surface corresponding to the shape of a cylinder and a plurality of recessed portions located about the circumference of the mandrel. The recessed portions are inwardly recessed from the substantially cylindrical outer surface and are separated by a plurality of connecting portions corresponding substantially to the cylindrical outer surface. The container body is subjected to vacuum attraction through a plurality of apertures provided in the mandrel whereby the container body is drawn into the plurality of recessed portions to conform the shape of the container body to the shape of the mandrel. The container is thereafter disengaged from the mandrel by feeding compressed air through the plurality of apertures of the mandrel.
