Abstract: A method for the manufacture of a vehicle wheel from light metal with an asymmetric rim base, which is made from a plate or disk by rolling, pressing, cutting and aperture-forming steps. In order for the wheel to be formed in a simple manner without costly manufacturing steps, the edge of the disk or plate is angularly bent, according to the method of the present invention, prior to splitting and the subsequent forming of the rim base. This is necessary in order for the rim base to be formed with different lengths of legs having the same thickness.

Abstract: PURPOSE:To keep off any increase in a braking distancce at a rough road, by constituting a braking pressure warming signal so as to be given to a hydraulic control circuit at a time when frequency in the braking pressure warming signal out of a discrimination circuit is more than the setting value or a pluse separation space is below the setting one. CONSTITUTION:The detected value of a wheel speed detector 1 is converted into a voltage signal with a frequency-voltage converter 2, and this voltage signal is inputted into both of a discrimination circuit 3 and an operation circuit 4. And, at this discrimination circuit 3, a fact that whether there is a possibility of locking a wheel or not is judged and outputs a braking pressure warming signal from one side of output terminals 3a. In this case, one side of these output terminals 3a is connected each to one side of input terminals of an AND gate 9 and an input terminal of a monostable circuit 10. And, a filter circuit 11 outputting only such a braking pressure warming signal as being more than the specified time in a pulse separation space. With this constitution, the braking pressure warming signal outputted from the discrimination circuit 3 at a time when there is no possibility of locking the wheel is prevented from being given to a hydraulic control circuit 6.

Abstract: The contact component is spherical, and has an inner ball-shaped body (4), and an outer spherical shell (5). It incorporates a pressure-sensitive medium (6), e.g. a material with piezo-electric properties, or one whose resistivity alters with pressure. Connections (7,8) are provided, as is a unit (9) for detection of changes occurring when the contact component comes into mechanical contact with a measurement object.

Abstract: An enhancement MOSFET Q1 is turned on by pulses P1 and turned off by pulses P2. The P1 pulses charge the gate capacitance of Q1 via D1 and R1, and turn off the depletion MOSFET Q2 via D3 and R4. The P2 pulses turn on PNP transistor Q3, which discharges the gate capacitance of depletion MOSFET Q2, thereby turning Q2 on and discharging the gate of Q1. Q2 provides a discharge path for dv/dt transients which couple to the gate of Q1 from its drain when the switch S1 is closed. Q1 may be in a converter circuit. <IMAGE>
