When a slip value of the driven wheel (1RR, 1RL) on a road surface reaches a predetermined value, the slip control is implemented to apply a braking force to the driven wheel (1RR, 1RL) as well as to decrease torque to be generated by the engine (2). When the brake is operated manually, or when a foot brake is stepped down, only the slip control by application of the braking force to the driven wh...

When a slip value of the driven wheel of a vehicle on a road surface reaches a predetermined value, the braking force is applied to the driven wheel by means of slip control. The slip control by application of the braking force to the driven wheel is inhibited when the vehicle speed reaches a high speed above a predetermined vehicle speed.

The light table for X-ray photography is produced by using a graphic screen (20) coupled to a microprocessor (23) and used in reverse video. Under these conditions, the graphic screen emits light at almost all points except at special places (I25) whose position can be controlled by means of a control unit (24). An X-ray photograph (6) to be examined is placed over the graphic screen. It is possib...

In order to solve handling problems which arise during use of a mammograph, the x-ray tube of the mammograph is carried by the end of an arm which rotates about an axis at right angles to the arm. The other elements of the mammograph are carried by another arm which is placed in a plane parallel to the plane of rotation of the first arm and rotates about the same axis. It is shown that, by moving ...
