DOLLAR A Drehknöpfe (2, 23, 41) mit Tastfunktion, die Bestandteil eines Drehschalters (20) und/oder eines Drehstellers (1) sind, finden in Bedieneinheiten, beispielsweise der Kraftfahrzeugtechnik, ihren Einsatz. Dabei ist im Drehknopf (2, 23) eine Taste integriert, die die Tastfunktion aus der Stirnfläche des Drehknopfes (2, 23) heraus realisiert. Diese Taste ist jedoch nicht unabhängig von der Drehverstellung des Drehknopfes (2, 23). Dadurch wird die Taste immer mit verstellt. DOLLAR A Hiergegen sieht die vorliegende Lösung vor, in einen Drehknopf (2, 23) eine Taste (5, 30) funktional losgelöst von diesem zu integrieren, so daß bei Verstellung des Drehknopfes (2, 23) die Taste (5, 30) nicht mit verstellt wird. Dazu ist innerhalb des Drehknopfes (2, 23) eine Halterung (6, 24.1) angebracht, wodurch der Drehknopf (2, 23) und die Taste (5, 30) konstruktiv miteinander verbunden, jedoch funktional getrennt sind. Die Drehverstellung wird durch den Drehknopf (2, 23) übertragen, während über die separate Taste (5, 30) die Tastfunktion durchgeführt wird.

Patent EP-1034968-A1 (EP)
Inventor: SASAKI SHOICHI
IPC: B60L50/16
Filed: 2000-03-10
Abstract: In a multiple power source system of the present invention
that has an inverter connected to a reactance, such as three-phase
coils in a motor, a high voltage battery is connected with a low
voltage battery via one transistor (Tr2) and one diode (D2) included
in the inverter and one phase coil (U-phase coil) of the three-phase
motor. The transistor Tr2 is turned on to make the electric current
flow from the low voltage battery to the U-phase coil. The
transistor Tr2 is subsequently turned off at a preset timing, so
that the electric energy accumulated in the reactance, that is,
the U-phase coil, flows through the diode D1 into the high voltage
battery and thereby charges the high voltage battery. This
arrangement enables the charging process from the low voltage
battery to the high voltage battery without any complicated circuit
structure for the voltage step-up. The three-phase motor may be
unipolar driven with transistors connected to one side of the
inverter. The arrangement of the present invention does not
require any complicated structure, which undesirably increases the
size of the multiple power source system, in order to ensure mutual
supplement of the electric energy between electric systems having
a large difference in voltage, for example, an electric system for
driving a hybrid vehicle and an electric system for its control
circuit.

Abstract: A pulley unit improved in the axial positioning of the cage (12) of
the one-way clutch is disclosed. The outer radius of the
orbital portion of the inner rings (21,31) of two rolling bearings
