Particularly, the use of dicyclopentadiene can give a hydrogenated product of ring-opened cyclic olefin polymer excellent in heat resistance, and this product can be advantageously used as parts or formed products for medical appliances or electrical components.

Abstract: A method and a device for controlling a wiper motor of a motor vehicle. A rain sensor sends signals to a control device and the wiper motor is switched off when a first threshold is exceeded or is not reached. After a defined time period after switching off the wiper motor, the wiper motor is switched on in order to remove residual wetness when the signals exceed or drop below a lower, second threshold.

Abstract: The seat cushion of a seat can be tilted about its longitudinal center axis for generating a tilting movement of the pelvis of a seat occupant. For generating the tilting movement, an adjusting element is provided in each of the right and the left area of the seat cushion. The adjusting elements interact to cause an opposite adjusting movement in the vertical direction, whereby the tilting movement of the pelvis is achieved. The adjusting elements are constructed, for example, as liquid-filled rolling bellows, in which case a sliding vane rotary pump changes the volume of the two adjusting elements in a diametrically opposed manner.
