Abstract: An aluminum alloy for die-casting capable of being used in high pressure die-casting method, and capable of providing a product having a sufficiently high strength and elongation without T6 treatment after casting and endurable under a corrosive atmosphere. Such aluminum alloy is used as a material of a subordinate frame for an automobile. The aluminum alloy contains from 8.0 to 9.0 mass % of Si, from 0.35 to 0.45 mass % of Mg, from 0.3 to 0.4 mass % of Mn, from 0.002 to 0.008 mass % of Be, less than 0.20 mass % of Fe, not more than 0.2 mass % of Cu, not more than 0.1 mass % of Zn, not more than 0.1 mass % of Ni, not more than 0.1 mass % of Sn, and remainders of Al and inevitable impurities. High pressure die casting is performed with this alloy by a die-casting machine provided with a seal ring disposed over a plunger tip, liquidized gaskets, a sealing rubber and a pin seal plate those being capable of providing high seal-ability and high vacuum in a mold cavity.

Abstract: A display control apparatus of this invention includes a touch panel for inputting a predetermined input, a liquid crystal monitor for displaying and switching a plurality of operation screen to display a desired operation screen in accordance with the predetermined input inputted by the touch panel, and a control unit for, when the operation screen to be displayed on the liquid crystal monitor in accordance with the predetermined input inputted by the touch panel corresponds to a password input screen for receiving input of a password, controlling the field angle of the liquid crystal monitor to a predetermined field angle.

Abstract: Disclosed is a collapsible core for use in a casting and a method for producing the collapsible core. The collapsible core comprises a main core body, a first layer formed over the core body, a second layer formed over the first layer, and a third layer formed over the second layer. The second layers includes a thermosetting resin such as low temperature decomposable resin. The low temperature decomposable resin comprises one of urea resin and phenol resin. The thermosetting resin is applied to the first layer by dipping, spraying or brush-painting. This thermosetting resin provides tight bonding to the neighbouring layers.
