    摘要: A column address is decoded by each column decoder, and an arrangement of pixels to be written to a memory cell array is rotated by a rotation circuit. The rotation result is written to the memory cell array in accordance with the decoding result of the column address. Then, the column address is decoded by each column decoder to a decoding result which is different from the decoding result of the column address at the time of writing. In accordance with the decoding result, pixels stored in the memory cell array are read. The arrangement of the read pixels is rotated by the rotation circuit and then outputted. Thus, rearrangement of pixels constituting an image can be carried out quickly while avoiding any increase in the size of the device.

    摘要: A system for controlling a speed of a vehicle having a continuously variable transmission (CVT) and a cruise controller which controls the traveling speed of the vehicle to a desired speed in response to an instruction to cruise control inputted by a vehicle operator. In the system, the speed ratio is fixed to a value, at which the instruction to cruise control is inputted, for a predetermined period of time since inputting of the instruction to cruise control. The speed ratio may be fixed to the value until the throttle opening has stabilized or the vehicle speed is equal to the desired vehicle speed even after the predetermined period of time has elapsed. Alternatively, a parameter indicative of upslope of the road where the vehicle climbs is determined and the speed ratio may be controlled-based on the parameter and the vehicle speed, or thereafter until the throttle opening has stabilized or the vehicle speed is equal to the desired vehicle speed. With this, the system can reduce throttle opening change and can decrease variation in vehicle speed when the cruise control is effected.

    摘要: For a semiconductor integrated circuit having an internal booster circuit such as a flash memory, voltage booster circuits capable of generating a boosted voltage 10 times or more as high as a relatively low source voltage is to be realized. Charge pumps for carrying out first stage voltage boosting on the basis of a source voltage are configured of parallel capacity type units, and charge pumps for carrying out second stage voltage boosting on the basis of the boosted voltage generated by the first charge pumps are configured of serial capacity type units.

    摘要: A tire (12) used includes a steel belt in its outer circumferential portion. A magnetic sensor (14) including a pair of magnetic detection elements (18A, 18B), which are arranged so that their magnetic detection directions become parallel to each other or series each other, is set in the vicinity of a rear tire (12) in a trunk room of a vehicle (10). Changes in magnetic field upon revolution of the tire (12) are differentially detected by the magnetic detection elements (18A, 18B), and the revolution of the tire (12) is detected on the basis of the differentially detected output waveform. Among a plurality of peaks present in the differentially detected output waveform, a peak, the potential difference from the immediately preceding peak of which is equal to or larger than a predetermined threshold value, is detected as an effective peak, which is effective for tire revolution detection, and the revolution speed of the tire is calculated by detecting the number of effective peaks.
