Abstract: A rear wheel turning mechanism of a four wheel steering system includes a rear wheel turning rod (4) which is connected to the rear wheels (18L,18R) of the vehicle and is adapted to be displaced so as to turn the rear wheels. An electric motor is operatively connected to the rear wheel turning rod and the steering wheel so as to displace the rear wheel turning rod, which turns the rear wheels in response to the operation of the steering wheel. A rear-wheel-neutralizing spring urges the rear wheel turning rod to the neutral position in which the rear wheels are held in the straight-ahead position. A clutch is interposed between the electric motor and the rear wheel turning rod and is adapted to disconnect the latter from the former to permit the latter to return to the neutral position under the force of the rear-wheel-­neutralizing means.

Abstract: In a matrix of capacitive key cells (A1,A2,B1,B2) of the type including a contact switch (20) in series with a key cell capacitor (21), an intracell coactive loading capacitor (22) is connected between ground and the junction (23) of the contact switch (20) with the key cell capacitor (21). A matrix of key cells (A1,A2,B1,B2) so formed is self-referencing, in that the need for a separate reference capacitor to load a sense line (50) is eliminated. Instead, loading is provided intrinsically by the effect of the intracell coactive loading capacitors (22) acting through multiple key cells (A1,A2,B1,B2) connected to a sense line (50).

Abstract: The invention relates to an assembling method for drive or coupling elements - such as cams, gears, crank webs - or bearing elements - such as plain bearing bushes or complete antifriction bearings on tubes or tube sections - by hydraulic expansion for producing built-up camshafts, transmission shafts, crankshafts or the like. The tubes are here expanded solely in the area of the respective elements beyond the elastic limit towards permanent elastic pretension in the elements. To relieve the seals adjoining the areas to be expanded, a counterpressure lying above the ambient pressure is produced according to the invention in the intermediate or end areas.

Abstract: In a frequency-dividing circuit for producing an output having a frequency half that of its input, a pair of terminals of a latch circuit (20) are connected to input terminals of a pair of delay means (31,32), and are also connected to receive through a pair of transistors  (11,12), the outputs of the delay means. A single-phase input signal (CK) is input to the control electrodes of the transistors to turn on and off the transistors. When the transistors are turned from off to on, the output states of the delay means are transferred through the transistors to invert the latch circuit, and the states of complementary terminals of the latch circuits are in turn transferred through the delay means to invert the output states of the outputs of the delay means. When the transistors are turned from on to off, no change occurs in the states of the circuit. In this way, the states of the circuit are inverted each time the transistors are turned from off to on. A frequency-divided output can therefore be derived at one of the outputs of the first and second delay means. Either one or both of the first and second inverters (21,22) may be replaced by a NAND gate or a NOR gate for permitting reset of the circuit.

Abstract: A symmetric integrated FET amplifier (e.g., 30) is disclosed which exhibits a DC offset voltage that is insensitive to power supply variations, as well as variations in the threshold voltages of the FETs forming the amplifier. These variations are known to be most prevalent in InP-based FET amplifier arrangements. The symmetry is achieved by using a pair of impedance matching elements (e.g., 44, 46) in the input stage of the amplifier to essentially match the impedance of the input FET and its load element; a matching buffer FET (e.g., 48) and diode level shifting arrangement (e.g., 50) are used to match similar elements present in the output branch of the amplifier structure. The impedance matching elements, as well as the level shifting diodes, may all be formed with FET structures to minimize fabrication problems. In accordance with the symmetric arrangement of the present invention, the output DC offset voltage will be maintained at zero volts, regardless of the variations noted above. A multistage symmetric amplifier may then be formed simply by directly connecting a number of single stage symmetric amplifiers together in series.

Abstract: A plasma processing device intended to plasma-­process a wafer which is mounted on a mount in the plasma process vessel and clamped at the peripheral rim thereof between a clamping member and the mount. The wafer thus processed can be then handled when it is released from its clamped state. A plate spring is housed like a cantilever in a part of that portion of the clamping member which clamps the wafer relative to the mount, and a free end of the plate spring is pro­jected from a recess which is formed on the underside of the clamping member to house the free end. When the wafer is clamped between the clamping member and the mount, the free end is housed in the recess, but when the wafer is released from its clamped state, the free end is projected from the recess to separate it from the clamping member. The wafer can therefore be left on the mount without adhering to the clamping member.
