  • Publication number: 20240014583
    Abstract: A battery post terminal assembly includes a battery post terminal including a grasping portion capable of grasping a battery post on an inner side, and a fastening portion placed in a form of a pair to extend from end portions of the grasping portion, a holder placed on one side of the fastening portion, and a base member placed on an opposite side to the holder with the fastening portion between the holder and the base member. The base member has a base seat portion, a screw shaft that is provided on one surface of the base seat portion to be coupled to the holder, and a projection portion that is provided on a surface having the screw shaft of the base seat portion, and to project to an inner side of the fastening portion when coupled to the holder.

  • Patent number: 6555594
    Abstract: There is provided a photo-curable, electrically conductive composition which is capable of forming a lower layer (black layer) electrode circuit satisfying both the sufficient conductivity and blackness after calcination in the formation of an electrode on a front substrate of a plasma display panel (PDP). The composition comprises, in the first fundamental mode thereof, (A) electrically conductive black fine particles having a specific surface area of more than 20 m2/g,(B) anorganic binder, (C) a photopolymerizable monomer, and (D) a photopolymerization initiator, and in the second mode further comprises (E) inorganic fine particles besides the above components.

  • Patent number: 6312864
    Abstract: Disclosed is a method for producing a patterned calcined inorganic film such as an electroconducting or insulating (non-conductive) film, particularly a plasma display panel, embracing a calcining step. To produce a patterned calcined inorganic film without inducing warpage, shrinkage of line width, or breakage of patterned lines, a patterned film formed on a substrate with a composition containing a heat decomposable binder and particles of an inorganic material is covered, prior to the calcining step, with a coating film of a heat decomposable resin composition capable of hardening or drying at a temperature lower than the temperature at which the heat decomposable binder is thermally decomposed and further capable of being burned off below the highest temperature of the calcining profile and thereafter the calcining step is performed.
