Patent number: 7006879Abstract: In a separate process from a boring process, the prealignment is performed beforehand on the circuit board, employing an alignment device, to create the positional data indicating the position of boring the hole in a pattern within the circuit board. In the boring process, the circuit board is carried into the working apparatus. The panel alignment is made on the circuit board. The positional data for positioning the circuit board on a table of the working apparatus is created. The synthesis of the positional data created by the prealignment and the positional data created by the panel alignment is performed to calculate the boring position of the circuit board on the table. The hole is bored at the calculated position in the circuit board, employing a boring machine of the working apparatus. Thereafter, the circuit board is carried out from the working apparatus.Type: GrantFiled: October 23, 2001Date of Patent: February 28, 2006Assignee: Nitto Denko CorporationInventor: Hitoshi Ishizaka

Publication number: 20030219608Abstract: A metal transfer sheet which is so low in peel-strength as to be transferred to an object to be transferred with ease and reliability; a producing method thereof; and a ceramic condenser producing method for producing a reliable, compact, thin-layer ceramic condenser with improved production efficiency by transferring a metal layer to the ceramic condenser by using the metal transfer sheet. After a first metal layer is formed on a carrier film in a sputtering or an electrolytic plating method, the member thus formed is dipped in plating solution and voltage is applied in such a way that the first metal layer side is anode, to form a passive film. Sequentially, with the polarity reversed, voltage is applied in such a way that the passive film side is cathode, to form the second metal layer. After this manner, a metal transfer sheet in which the first metal layer and the second metal layer are laminated through the passive film interposed therebetween is obtained.Type: ApplicationFiled: May 21, 2003Publication date: November 27, 2003Inventors: Hitoshi Ishizaka, Yasuhiko Yamamoto, Kazuo Ouchi, Takashi Oda, Takuji Okeyui
