Title: Position setting method of electrode of melting tank and input electric power control method
Inventor: IKEDA NOBUHIKO
IPC: F23G5/50
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To set electrodes to a proper position in melting slag, and prevent abrasion of the electrodes and reduction in durability of a melting tank by detecting a sudden change in an electric current or voltage when the tip of the electrode makes contact with a molten metallic layer by lowering the electrode, and raising this electrode by a preset height. SOLUTION: Among plural electrodes, one electrode 2B is rested by being soaked in the vicinity of a surface of melting slag 4. The other electrode 2A is lowered from this condition, and is soaked in a molten slug 4, and is lowered in the molten slug 4. An electric current is carried between the electrodes 2A and 2B through the molten slug 4 from when the electrode 2A contacts with an upper surface of the molten slug 4. When the tip of the electrode 2A reaches an upper surface 3A of melting metal 3, an electric current flowing in the electrodes 2A and 2B or voltage suddenly changes. An electric current or voltage detecting means detects this moment, and outputs a detecting signal. By this signal, the electrode 2A is stopped by being raised by a preset height h1 from a position contacting with the upper surface 3A of the molten metal 3.  Next, in the electrode 2B, a position is set similarly to a case of the electrode 2A.

Title: Clamping force-setting method in toggle-type mold clamping device
Inventor: OBAYASHI TADANORI
IPC: B29C45/80
Filed: 1993-12-28
Abstract: PURPOSE:To adjust a clamping force of a mold clamping device without using a large- size tie bar nut driver by a method wherein at an arbitrary mold opening position where molds do not compress a spring, a whole of a movable part of the mold clamping device is traveled in a mold opening direction by a net travel amount found by adding a corrective travel amount to a reference travel amount. CONSTITUTION:A position where molds 38, 40 hold a spring 16 in a free length with a toggle mechanism 12 expanded is determined as a reference position. A mold clamping device is traveled with the toggle mechanism 12 kept as it is. In this manner, the mold clamping device is positioned on the reference position, and a gap between the parting surfaces of the molds is measured. A reference travel amount of the mold clamping device for producing a force in a clamping direction and a corrective travel amount of the mold clamping device based on the gap and the force of the spring 16 are calculated. At an arbitrary mold opening position where the molds 38, 40 do not compress the spring 16, a whole of a movable part 30 of the mold clamping device is traveled in a mold closing direction by a net travel amount found by adding a corrective travel amount to a reference travel amount.

Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and flat integrated circuit wafer surface and to remove tungsten-stringers from the surface by limiting the deposition of material on the peripheral region so that the peripheral region may have improved uniformity and flatness and the probability of generation of stringers may be lowered. SOLUTION: An IC 100 has an active die region 112 and a peripheral region 114. 'Perfect' dies 104 exist in a die region 112. 'Partial' dies 102 exist in the selected parts of the peripheral region 114 and are in the positions adjacent to edge-dies. The perfect die 104 includes all circuits necessary for the function of an IC. The die 102 cannot operate, but it can effectively reduce the deposition of material in the peripheral region 114. Thus, the IC is prevented from not operating due to potential risks such as nonuniformity, imperfect flatness, and electrically conductive stringers such as tungsten-stringers.
