| 20080257472 | METHOD FOR MANUFACTURING CERAMIC PLATES - In a method for manufacturing ceramic plates, a Pd paste which does not diffuse into ceramic is formed in a metal paste forming step; metal films each having a thickness such that ceramic layers to be formed after firing are not connected to each other in the lamination direction are formed on surfaces of ceramic green sheets using the Pd paste in a metal film forming step; following a laminate forming step, a firing treatment at a firing temperature, which is a high temperature at which no glass component remains on surfaces of the ceramic layers after the firing and which is equal to or lower than a decomposition temperature of a ceramic material forming the ceramic layers, is performed for a laminate in a firing step; oxygen present at the interfaces between the ceramic layers and the metal layers is removed by immersing a sintered body in n-butyl alcohol in a separation step so as to separate the ceramic layers and the metal layers. Accordingly, ceramic plates having a very small thickness can be manufactured without causing any damage thereto and with high efficiency and can be easily applied to laminate type electronic components. | 10-23-2008 |
| 20110024033 | Laminated Pieozelectric Ceramic Element Manufacturing Method - There is provided a laminated piezoelectric ceramic element manufacturing method, wherein, even when the number of internal electrode laminations is increased, the lamination and cutting steps can be simplified, to enhance cutting precision and make cutting cost low. A first laminated body having stripe-like internal electrodes is cut into a plurality of second laminated bodies so as to have a width-direction dimension W corresponding to a width dimension of a laminated piezoelectric ceramic element chip to be ultimately obtained. Two or more second laminated bodies are laminated in the laminating direction to obtain a third laminated body, and the third laminated body is cut in the laminating direction and parallel to the width direction W to obtain a laminated piezoelectric body. | 02-03-2011 |
