  • Patent number: 9168730
    Abstract: A method of partially imaging a substrate, for example glass, with a print pattern comprising layers of ceramic ink in substantially exact registration. The method relies on a mask ink layer defining the print pattern and differential thermal expulsion of ceramic ink medium during a heat fusing process between the areas outside the print pattern and within the print pattern. This results in pigment and glass frit forming a durable image material adhered to the substrate within the print pattern and non-durable material outside the print pattern, enabling its removal outside the print pattern to leave the desired layers of ceramic ink within the print pattern in substantially exact registration.

    Abstract: A conventional, multilayer, all-solid-state, lithium ion secondary battery where an electrode layer and an electrolyte layer are stacked has a problem that it has a high interface resistance between the electrode layer and the electrolyte layer and has a difficulty in increasing the capacity of the battery. A battery has been manufactured by applying pastes of a mixture of an active material and a solid electrolyte to form electrode layers and baking a laminate of electrode layers and electrolyte layers at a time. As a result, a matrix structure including the active material and the solid electrolyte has been formed in the electrode layers, so that a battery with a large capacity and a reduced interface resistance between the electrode layer and the electrolyte layer has been successfully achieved.

  • Publication number: 20140138122
    Abstract: A method for making an extruded insulator for a spark plug in a manner that minimizes pores, relics and/or other defects in the insulator microstructure so that the overall dielectric strength or performance of the insulator is improved. The method may be used to manufacture an extruded insulator that avoids many of the drawbacks associated with such defects, but also has a stepped internal bore for receiving a center electrode. In one embodiment, the method uses a multi-phase extrusion process to extrude a ceramic paste around an elongated arbor and form an extruded section, and then removes the arbor from the extruded section to reveal a stepped internal bore.

  • Patent number: 8647560
    Abstract: A groove and a recess are formed on one surface of a base material, the recess being communicated with the groove and having a width and a length longer than a width of the groove. After that, liquid droplets are landed on the recess to charge a liquid into the groove communicated with the recess. Further, the liquid charged into the groove is solidified. Accordingly, the liquid can be charged into the groove having the narrow width, by merely landing the liquid droplets on the recess having a large areal size. Therefore, a fine pattern can be easily formed on the base material.
