Abstract: PROBLEM TO BE SOLVED: To obtain both of turn behavior stabilizing action and vehicle driving force in conducting control operation for stabilizing the turn behavior of a vehicle. SOLUTION: A gear stage which is fixed by a gear state determining means 176 is determined by a gear stage determination means 174 at the time of turn behavior control starting of a vehicle by a turn behavior control means 160, based on the running resistance R of a vehicle which is calculated by a running resistance calculating means 168, the output torque TE of an engine 10 which is calculated by a driving-motor output calculating means 170, or vehicle driving force F which is calculated by a vehicle driving force calculating means 172. The gear stage of an automatic transmission 14 is fixed during turn behavior stabilizing control, therefore, the stability of a vehicle turn behavior is obtained regardless of the deviation between an actual yaw rate and a targeted yaw rate.  Also, the gear state is fixed, which is determined based on the actual running resistance R, the output torque TE of the engine 10, or the driving force F of the vehicle at the time of the control starting during the turn behavior stabilizing control, thus it is possible to eliminate shortage of driving force in the vehicle.

Abstract: PURPOSE:To spread and supply a high water content residue widely uniformly by provided a plurality of blades, in which the side shape is bow-form on the periphery of a rotor of a spreader and the front shape allows the outer circumferential end to be in the form of a recess and a projection, at specified pitches in the circumferential direction of the rotor. CONSTITUTION:With regard to parts in which the outer circumferential end of the front shape of blades 45 is in the form of a recess and a projection, in the case of a projection part circumferential speed is large, it continuously becomes small as it is allowed to approach to the recess part of a root by the rotation of a rotor 44 and a release arrival distance is different by different circumferential speed, so a high water content residue 30 is diffusively supplied on a fluidized surface uniformly. Furthermore, after the high water content residue 30 collides with the blades 45 in the case where the side face shape of the blades 45 is in the form of a blow, the residue 30 is released at a large elevation angle because it is released in the tangential direction and nearly right angles of a blade face, so that it can be diffusively supplied on the fluidized face further and uniformly as the whole by two synergetic effects.

Abstract: PURPOSE:To dynamically vary the number of times of key scan per unit time by providing a pressure detecting means and a key scan control means to indicate the scan speed of a key to a key scan means corresponding to the pressure signal of the pressure detecting means. CONSTITUTION:The key scan means 2 starts the scan of the key for a key input means based on a command from an input signal processing means 1. At this time, the number of times of the scan per unit time for the key input means 3 performed by the key scan means 2 is controlled by a signal from the key scan control means 5. In other words, the pressure of the key depressed on the key input means 3 is detected by a key pressure detecting means 4, and the pressure signal corresponding to a pressed force is generated, and it is delivered to the key scan control means 5. The key scan control means 5 generates a control signal to increase the number of times of scan of the key per unit time as the pressure to press the key is increased, and delivers it to the key scan means 2. In such a way, it is possible to input information as varying the scan speed of the key dynamically.
