Abstract: PURPOSE: A device for preventing an electric power consumption of a multiple power system is provided to prevent an electric power consumption when a test is operated in a system being supplied a multiple power. CONSTITUTION: A plurality of sub blocks(100-200) are operated by a multiple power and perform a predetermined interface operation in a mobile electronic system being supplied from a multiple power. An interface logic(300) is connected between output pins(110,210) of each sub block and performs an interface function between the sub blocks in a normal mode. In a test mode, the interface logic(300) processes an output pin of the sub block as a ground and blocks a current path. When an interface is operated from the first sub block(100) to the second sub block(200), a data path is formed between the output pins of the sub blocks through the interface logic(300). When an interface is operated from the second sub block(200) to the first sub block(100), a data path is formed between the output pins of the sub blocks.

Abstract: PURPOSE: The polymer optical elements by using a board of a high thermal expansion coefficient are provided to stabilize the progresses of etching or packaging by making the internal stress, which can be generated, to minimum and making the difference of thermal expansion coefficient between a board and the polymer material. CONSTITUTION: The polymer optical elements by using the board of the high thermal expansion coefficient include a graph. In the graph, the same polymer is coated on a silicon board and a stainless board and the progress of heat treatment is carried out in the same condition and the change of internal stress according to the case of using the silicon board in cooling is measured. In case of using the stainless board, the declination, in which the internal stress is increased, is decreased. The polymer including the high thermal expansion coefficient has the high final remaining internal stress value by more contraction than the board. But the stainless board has the thermal expansion coefficient close to the polymer, so the final internal stress value is reduced.
