IPC: B60T8/58
Filed: 1995-09-20
Abstract: PURPOSE: To provide a braking force controller constituted so as to control a braking force of each wheel so that the traveling stability in turning braking is improved. CONSTITUTION: An antilock braking force control circuit 60, when a brake switch 67 is changed over to ON, reads the acceleration detected by an acceleration sensor 62, the rotational speed of each wheel detected by wheel rotation sensors 63-66 and the car body speed detected by a vehicle speed sensor 61. The control circuit 60 calculates the aimed wheel speed of inner wheel in turning so that left and right wheels are simultaneously locked on the basis of the car body speed, turning outer wheel speed and lateral acceleration, and controls a braking force for the turning inner wheel to provide the aimed wheel speed obtained by that calculation. Thus, the brake pressure is controlled to provide the same slip ratio in each wheel so that the traveling stability in the turning braking can be improved while a braking distance can be shortened to improve the braking performance.

Filed: 1989-09-19
Abstract: PURPOSE:To provide a plasma cleaning apparatus capable of substantial reduction of time required for cleaning by a structure that comprises a shield for protecting the inner wall of a vacuum chamber and cooling pipe for the shield. CONSTITUTION:Cleaning gas 11 such as an etching gas is supplied to a plasma chamber 1, and microwave 10 is applied to produce a plasma of the cleaning gas. The plasma is guided along the field furnished by first and second solenoids 7 and 8 onto the inner wall of a shield 17. As a result, reaction products on the wall of the shield are etched away. A cooling pipe 18, in which coolant 19 is circulated, is wound around the cylindrical shield 17. When the shield is cleaned by a high-density plasma, therefore, the shield is kept from heating. The flow rate of the coolant to a vacuum chamber is so adjusted that the reaction products on the inner wall of the shield is effectively removed at controlled temperature. This results in a substantial reduction in time required for cleaning.
