Title: Sticking jig for polishing liquid epitaxial growth film and polishing method using the same
Inventor: KUMATORIYA MASATO
IPC: B24B41/06
Filed: 1994-02-24
Abstract: PURPOSE:To enable a smooth and high quality single crystal film to be formed by polishing the same while keeping a specific thickness thereof without removing the projections formed on a substrate having the single crystal film formed thereon by cutting off the same by forming the recessions opposite to the projections of the single crystal film on the surface in contact with the single crystal film. CONSTITUTION:Within the sticking jig 5, recessions 5a-5c opposite to the projections 4a-4c of a single crystal film 4 formed by liquid epitaxial process are to be formed on the surface in contact with the single crystal film 4. Furthermore, one main surface of the single crystal film 4 formed by the liquid epitaxial process is sticked on the sticking jig 5 formed of the recession 5a-5c on the parts corresponding to the projections 4a-4c on the other main surface of the single crystal film 4 using a bonding agent 6 and then the opposite main surface of the single crystal film 4 is to be polished. Through these procedures, the sticking jig 5 and the single crystal film 4 can be stuck to each other making no gaps at all between them thereby enabling the bend of an underneath substrate 1 to be avoided as well as the single crystal film 4 to be polished while keeping a specific thickness thereof.

Title: Forming die for extruded shape possessing tall fin
Inventor: SUGIO EIJI
IPC: B21C23/14
Filed: 1979-03-07
Abstract: PURPOSE: To greatly extend the life of titled die, by connecting to fix the neighborhood of tips of plural thin walled projections deeply extending into the open hole of main body of the die, to the bridge through the connector, in order to prevent the breakage of these projections due to the pressure of hot billet during the extrusion work.  
     CONSTITUTION: The billet (for example, aluminum billet), heated in the container of the extruder, is extruded and is fed into the open hole 13 of the guide vane 11 while the material flow is being dispersed by the H-type inflow interceptor 12 of the guide vane 11. Next, this billet is fed into the narrow hole 5a and the wide hole 5b of the opening 5 of the die 3. Hereupon, the hot billet on both sides of the bridge 8 is fed into the clearance 10 between connectors 9 so as to make the confluence together with, and is next fed into the narrow gap 5b between the projections 6. In this case, since the part 6a near the tip of each projection 6 is connected to the bridge 8 through the connector 9, the projection 6 is perfectly prevented from breakage and bending due to the extrusion force of the hot billet.
