Title: Method for bonding thin piece to mounting plate
Inventor: NISHIJIMA MASAO
IPC: H01L21/304
Filed: 1979-04-20
Abstract: PURPOSE:To obtain excellent flatness of the bonding surfaces by atomizing a solution of a bonding agent, applying said agent to a thin piece and a mounting plate, contacting said thin piece and said mounting plate, heating and compressing them, and making the bonding-agent layer thin. CONSTITUTION:Wax is resolved in a solvent, and the solution is atomized and floated in a clean gas. Then, said solution is applied on the contacting surfaces of a mounting plate and a wafer. In this method, a very thin film can be formed. The wafer and the mounting plate is contacted under this condition, then, heated and compressed. As a result, the extra amount of the bonding agent enters into the concave portions in the rough surfaces of both contacting plate, thereby a very thin layer is obtained. In this method, the mounting plate and the wafer can be bonded and machined without imparing the specified precision standard for the mounting plate and the wafer, and the wafer having the flatness of less than 1mum can be obtained.

Title: Manufacture of magnetic sheet for magnetic card
Inventor: KAJITANI TOSHIO
IPC: G11B5/84
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To improve a countermeasure against forging by completely removing a deviation between a printed position and the recording position of an information signal without making a reference hole on a magnetic card. SOLUTION: Patterns are printed on prescribed positions of a magnetic sheet 3 based on the end face of the sheet 3 in a printing process. The problem is generation of a deviation between a printed position and the recording position of an information signal by the elongation and contraction of a magnetic sheet coil 2 due to a thermal change caused by the passage of the coil 2 through a dry path at the time of a 2nd application process of magnetic ink. But when a magnetic mark reading magnetic head 8 reads out the pitch interval of magnetic marks 6, the length of the sheet 3 is recorded and the position of a printing plate is adjusted in accordance with the length of the sheet 3 in a succeeding printing process. Thereby a deviation between a printed position and the recording position of an information signal can be completely removed.
