Title: Vehicle behavior control device
Inventor: KADOSAKI SHIROU
IPC: B60T8/1755
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of the hunting of the behavior control attributable to the excessive generation speed of the yaw moment by reducing the generation speed of the braking force when the performing time of the behavior control by a braking force control means is long. SOLUTION: When a vehicle turns, a CPU 72 first reads the vehicle speed V detected by a vehicle speed sensor 76, and then, operates the deviation of the transverse acceleration between the transverse acceleration Gy and the product of the vehicle speed V by the yaw rate γ, i.e., the slip acceleration of the vehicle. The slip acceleration is integrated to operate the slip speed of the vehicle body, and the slip angle of the vehicle body is operated as the ratio of the slip speed to the longitudinal speed of the vehicle body. Then, the spin quantity as the linear sum of the slip angle and the slip acceleration is operated, and the upper limit value of the duty ratio in a valve to control the braking pressure is set smaller as the performing time of the spin suppression control is longer.  The generation speed of the braking force is reduced to reduce the generation speed of the anti-spin mode.

Title: Electrophotographic sensitive body
Inventor: NAKATANI KANAME
IPC: G03G5/14
Filed: 1992-11-05
Abstract: PURPOSE:To provide the photosensitive body with which a stable corona charge characteristic and a good light attenuation characteristic are compatible and which can be provided with an under coat layer thicker than the conventional under coat layer and can effectively prevent the generation of defects on images caused to the defect on the conductive base body by interposing the under coat layer having a nonlinear conductive characteristic of a varistor type between a conductive base body and a photosensitive layer. CONSTITUTION:This photosensitive body 1 consists of the conductive substrate 2, the under coat layer 3 provided on the substrate 2 and the photosensitive layer 4 provided on the under coat layer 3. The under coat layer having the nonlinear conductive characteristic of the varistor type is selectively used as the under coat layer 3, by which the high resistance is attained to suppress the implantation of the opposite charges from the base body 2 and the high electrostatic charge is enabled at the time of electrostatic charge. On the other hand, the low resistance is attained and the high voltage is lowered by the transfer of the charges under a high electric field at the time of illumination with light. The high corona charge characteristic and the good light attenuation characteristic are thus compatible. Since the under coat layer 3 is provided thickly without adversely affecting the light attenuation characteristic, the surface defect of the conductive base body 2 is concealed.
