Abstract: A nonvolatile memory working on a different operating voltage from a logical functional unit is to be operated at high speed with a single line voltage supplied from outside. A nonvolatile memory is disposed in a semiconductor integrated circuit device. This semiconductor integrated circuit device is provided with core regulators for generating from an externally supplied line voltage, different operating line voltages, a PLL regulator, a regulator for power supply circuit and a regulator for decoder. The regulator for power supply circuit and the regulator for decoder respectively generate, from the externally supplied line voltage, a first line voltage and a second line voltage to be supplied to the nonvolatile memory. The core regulators generate line voltages to be supplied to internal modules of the semiconductor integrated circuit device, and the PLL regulator generates a line voltage for the PLL.

Abstract: In an information processing system such as a navigation system or a portable information terminal unit, information output mode of a display unit to a user is switchable to a plurality of output modes. The navigation system switches the language to be used for information output to any one of Japanese language, English language, and German language. Not the input speech itself is used as a command, but whether the input speech is a Japanese language input, an English language input, or a German language input is determined. The language to be used for information output is switched depending on the determination result.

Abstract: An evaporating fuel control system includes a fuel tank, a pressure sensor for detecting a pressure in an upper space of the tank, a learning discrimination element for discriminating as to whether a zero point correction of the pressure sensor is once performed or not at all, a learning condition determination element for determining as to whether or not a learning condition is established in the case where the pressure of the tank is near the atmospheric pressure while a vehicle is normally running under the condition that the zero point correction is not performed at all, an air pressure return element for causing the upper space in the fuel tank forcibly to be a negative pressure by a negative pressure during a purging and for thereafter opening the fuel tank to the air, a zero point set element for setting an output value of the pressure sensor to the zero point after a predetermined time after opening the tank to the atmosphere, and correction means for correcting the output value of the pressure sensor

Abstract: A internal pressure adjusting system and method for a fuel tank mounted on an automobile is to provide a fuel vapor control system preventing from flowing out the fuel vapor to atmosphere while the engine is stopping. The internal pressure adjusting system and method is to further provide a fuel vapor control system preventing from flowing out the fuel vapor to the atmosphere by adjusting the internal pressure of the fuel tank in a proper value when the internal pressure excessively rises during refueling and operating the engine, and preventing from damage of the tank from excessively a negative pressure in the tank. Therefore, it never carelessly flows out the fuel vapor to atmosphere even if the large amount of fuel vapor is generated in the upper space of the fuel tank.

Abstract: A fail-safe system and method for automobile fuel tank wherein when the fuel filler cap is opened at fueling and the pressure in the fuel tank goes down to an atmospheric pressure level, the pressure sensor detects the pressure down and the pressure control valve provided between the fuel tank and the canister is automatically closed for a specified time. Therefore, even if a vehicle driver inadvertently forgets to switch the ignition key off at fueling, fuel does not flow out of the canister when the fuel tank is filled up. The system does not need any additional device.
