Abstract: 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 the instruction to cruise control inputted by the vehicle operator. In the system, the detected throttle opening is smoothed or filtered such that the speed ratio of the continuously variable transmission is controlled based on the smoothed throttle opening and the detected vehicle speed when the instruction to cruise control is input. Alternatively, a parameter indicative of upslope of the road where the vehicle climbs is determined and the speed ratio is controlled based on the parameter and the detected vehicle speed. With this, the system can reduce the engine speed fluctuation and can prevent the vehicle operator from feeling uneasy when the cruise control is effected.

Abstract: According to the present invention, in accordance with the first to fourth quadrants on the phase plane for signal points, a phase angle detector converts an I channel signal or a Q channel signal obtained by a demodulator, by using individually set operating expressions, so as to correlate the angle (phase angle) for a signal point on the plane phase with a predetermined one-dimensional coordinate. More specifically, the phase angle that extends from a border point in an arbitrary quadrant on the phase plane to a border position shifted 360° is allocated for a specific one-dimensional coordinate. The coordinate value on the one-dimensional coordinate is calculated by using the operating expression which is set in accordance with the first to the fourth quadrant of the signal point which is detected using the I channel signal and the Q channel signal.

Abstract: For example, when moving a cursor by a pointer of a note-type personal computer, the cursor can be rapidly moved to a target position, and can be stopped there. When the pointer is operated, the cursor intermittently moves in such a manner that the movement for a predetermined time period t1 and the stop for a predetermined period t2 alternate with each other. At this time, although the predetermined time period t1 of movement of the cursor is constant regardless of whether the amount of the inputting operation, applied to the pointer, is small or large, the speed of movement of the cursor is proportional to the inputting operation amount, and the predetermined period t2 of stop of the cursor is inversely proportional to the inputting operation amount.

Abstract: Disclosed herein is an evaporative emission control system which can properly control the ratio between a tank purge amount and a canister purge amount to realize quick pressure reduction in a fuel tank and ensuring the storage capacity of a canister in a well balanced fashion. A target pressure in controlling the pressure in the fuel tank at a negative pressure and a detected pressure in the fuel tank are compared with each other. When the difference between the target pressure and the detected pressure is large, tank purge is preferentially carried out to open a tank pressure control valve. When the detected pressure is in the vicinity of the target pressure, canister purge is preferentially carried out to purge the evaporative fuel stored in the canister.
