摘要:
A control apparatus for a vehicle for a continuously variable transmission (CVT) whose speed ratio is continuously variable, the apparatus including a mode selector responsive to a currently required output of an engine, for selecing one of a continuously variable speed mode in which the speed ratio of the CVT is continuously changed, and a stepping shift mode in which the speed ratio is changed in a plurality of steps. The apparatus further includes a first control device operable in the continuously variable speed mode, for continuously changing the speed ratio of the continuously variable transmission so as to operate the engine with minimum fuel consumption, and a second control device operable in the stepping shift mode, for selecting one of a plurality of speed-ratio positions corresponding to the above-indicated plurality of steps, and for maintaining the selected speed-ratio position, based on the detected currently required output of the engine and the detected running speed of the vehicle.

A route display apparatus and method are provided. The apparatus includes a search unit that searches for a plurality of routes in which a plurality of destinations are stopped by in a different stopping order combination in each route. The apparatus also includes a prediction unit that predicts, for each of the routes, a travelable position that can be reached with a remaining amount of a battery. The prediction unit is configured to predict, for each of the routes, a necessity of charging based on whether the travelable position is on a side of a departure point in relation to a final destination. The apparatus also includes a display control unit that displays, for each of the routes, the necessity of charging in association with a corresponding stopping order for each of the routes, on a display part.

A semiconductor device including an n-channel-type MISFET (Qn) having an Hf-containing insulating film (5), which is a high dielectric constant gate insulating film containing hafnium, a rare-earth element, and oxygen as main components, and a gate electrode (GE1), which is a metal gate electrode, is manufactured. The Hf-containing insulating film (5) is formed by forming a first Hf-containing film containing hafnium and oxygen as main components, a rare-earth containing film containing a rare-earth element as a main component, and a second Hf-containing film containing hafnium and oxygen as main components sequentially from below and then causing these to react with one another.

This invention provides a magnetic recording medium evaluation apparatus and evaluation method which yield results having good correlation with error rate measurements even when comparing media with different structures. Signals from a function generator are recorded in a magnetic recording medium. The recording signals are also passed through a first digital filter to obtain ideal restored signals. Reproduced signals from the magnetic recording medium are sampled in synchronization with the output from the function generator, and the discrete signals are passed through a second digital filter to obtain restored signals. The outputs from the first and second digital filters are input to an operational amplifier, and the difference between the restored signals and the ideal restored signals is taken for each sampling of the recording signals. The signal-to-noise ratio of the ideal restored signal to the average of the absolute value of this difference is used to evaluate signal quality.

摘要:
A semiconductor substrate is covered with a resist mask and then an opening for exposing a whole upper surface of a polysilicon gate is formed by photo lithography and dry etching. Thereafter, nitrogen ions are implanted into the polysilicon gate through the opening. Implantation energy at this time is set so that the implanted ions may not break through the polysilicon gate.

A method of producing a semiconductor device having a thickness of 90 μm to 200 μm and with an electrode on the rear surface, which achieves a high proportion of non-defective devices by optimizing the silicon concentration and thickness of the aluminum-silicon electrode. A surface device structure is formed on a first major surface of a silicon substrate. A buffer layer and a collector layer are formed on the second major surface after grinding to reduce the thickness of the substrate. On the collector layer, a collector electrode is formed including a first layer of an aluminum-silicon film having a thickness of 0.3 μm to 1.0 μm and a silicon concentration of 0.5 percent to 2 percent by weight, preferably not more than 1 percent by weight.
