  • Patent number: 5906568
    Abstract: An inner bag is adhered by an adhesive to the substantially entire region of a pouring spout attaching panel of a carton blank, and to substantially half regions of panels bordering the pouring spout attaching panel, which are on the side of a pouring spout. The inner bag is adhered to the carton at a part which is remotest from the pouring spout and is normal to a direction of movement made by the inner bag when air is drawn. The inner bag is adhered to the carton blank at the substantially entire region of the pouring spout attached panel, and four corners on the side of the panel, which enables the inner bag to be set up into a square shaft with high precision upon the setting-up of the carton blank.
    Type: Grant

  • Patent number: 5816449
    Abstract: An ink cartridge for use with, for example, a stencil printer and storing viscous ink therein is disclosed. The cartridge is free from damage and deformation during storage or transport in various kinds of atmospheres. Particularly, an ink outlet included in the cartridge is prevented from tilting. The cartridge can, therefore, be surely and accurately mounted to an apparatus. The ink outlet is protected from damage even when the cartridge is let fall by accident.

  • Patent number: 5803302
    Abstract: An inner bag is adhered by an adhesive to the substantially entire region of a pouring spout attaching panel of a carton blank, and to substantially half regions of panels bordering the pouring spout attaching panel, which are on the side of a pouring spout. The inner bag is adhered to the carton at a part which is remotest from the pouring spout and is nominal to a direction of movement made by the inner bag when air is drawn. The inner bag is adhered to the carton blank at the substantially entire region of the pouring spout attached panel, and four corners on the side of the panel, which enables the inner bag to be set up into a square shaft with high precision upon the setting-up of the carton blank.

  • Patent number: 5315319
    Abstract: A thermal plate-making apparatus has a line thermal head comprising a plurality of heat units aligned on a line. Each of the heat units comprises electrodes and plural heat elements located therebetween. The apparatus effectively prevents back face reprint of image in a stack of printed sheets, stains due to rubbing between the printed sheets, and dotted images, allowing printing of stable image density. Further, a thermal plate-making apparatus has a line thermal head comprising heat units aligned in a first direction, in which each of the heat units comprises a pair of electrodes opposed in a second direction perpendicular to the first direction and a heat element positioned between the electrodes, and in which the heat element is formed not lower than the electrodes. This apparatus also effectively prevents the back face reprint with the minimum ink transfer amount necessary for printing, providing a loyal print image.

  • Patent number: 5043784
    Abstract: An image sensor having a lower electrode disposed on a surface of a substrate; a multilayered amorphous silicon layer formed on the surface of the substrate so as to cover an end portion of the lower electrode; and an upper electrode formed on the surface of the substrate so as to cover an end portion of the amorphous silicon layer. An angle defined by an end surface of the end portion of the amorphous silicon layer and the surface of the substrate having the lower electrode disposed thereon is within a range of from 30.degree. to 60.degree. and a distance between edges of two neighboring layers of the amorphous silicon layer at the end portion of the amorphous silicon layer is equal to or less than 500.ANG..
