摘要： In a semiconductor storage device in a stack structure wherein a capacitor section having an upper electrode, a dielectric layer, and a lower electrode is connected with a transistor section by a plug, the lower electrode is formed in contact with the plug. The lower electrode is formed of at least an oxide of a platinum-rhodium alloy. In addition to the oxide of a platinum-rhodium alloy, platinum and/or a platinum-rhodium alloy can be used as materials for forming the lower electrode. The plug is formed of polysilicon or tungsten. When the plug is formed of polysilicon, the lower electrode is formed by sequentially laminating, for example, a film of the oxide of the platinum-rhodium alloy, a film of the platinum-rhodium alloy, and a film of the oxide of the platinum-rhodium alloy on the plug.

摘要： It is determined whether a vehicle enters a halting state or a slow moving state. It is detected that an accelerator opening degree of the vehicle is zero during a deceleration duration up to the time to enter the halting state or the slow moving state. Further, an accelerator zero duration is calculated which is a duration for which the vehicle is in the halting state or the slow moving state while the accelerator opening degree is zero. Furthermore, an accelerator zero travel distance is calculated which the vehicle runs during the calculated accelerator zero duration. Based on the accelerator zero travel distance, it is determined whether the fuel saving driving operation is performed in traveling during the accelerator zero travel duration. Even in the state where the travel speed of the vehicle changes more than needs during inertia travel, the fuel saving driving operation is diagnosed appropriately.

摘要： An electromagnetic wave matching element makes it possible to reduce the cost of a transmission system to a great degree. An electromagnetic wave matching element is adapted to allow electromagnetic wave beams incident from an entrance to be reflected by using plural mirrors to couple these reflected electromagnetic wave beams to an external transmission system through an exit. Mirrors are used that have a shape adapted to receive the plural electromagnetic waves in a beam form and to output electromagnetic wave beams having a predetermined distribution in which the number of the output electromagnetic waves is different from the number of the received electromagnetic waves.
