摘要:
A data processor includes a hardware translator converting non-native code into a native code to a processor, a software translator converting non-native code into a native code to the processor by software, and a software interpreter sequentially interpreting a code that is non-native to the processor, and executing the interpreted code using a native code of the processor. The data processor includes a circuit selecting the hardware translator, software translator or software interpreter according to a predetermined criterion for operation.

It is an object of the present invention to provide a method and an apparatus for driving a piezoelectric transformer capable of always driving with maximum conversion efficiency regardless of changes in the input voltage level, load and temperature, etc. The method and apparatus for driving a piezoelectric transformer of the present invention generate a time-varying sweep voltage through a sweep circuit at predetermined regular intervals, thereby changing the frequency of a drive signal output from a voltage control oscillator, at this time detect a phase difference between the voltage and current generated on the primary side of the piezoelectric transformer by a phase difference detector, and hold the sweep voltage corresponding to the timing at which a maximum value detector detects the maximum value by a sample-and-hold circuit, thereby controlling the frequency of the drive signal so that the phase difference between the voltage and current on the primary side of the piezoelectric transformer always becomes a maximum value.

A power source 1 and an operating circuit 4 incorporating a waveform generating circuit 5 for synthesizing composite wave W obtained by synthesizing a sine wave of primary oscillations and a sine wave of secondary oscillations of a Rosen-type piezoelectric transformer and an amplifying circuit 6 raises the voltage of the composite wave so that composite wave W' (having a waveform similar to that of W) is, as input voltage V.sub.in, supplied to the Rosen-type piezoelectric transformer PT. Thus, output voltage V.sub.out having greater output electric power and higher transmitting efficiencies as compared with output voltage which can be obtained from a conventional structure in which input voltage in a single oscillation mode is employed can be produced to load resistor R.sub.o.

A twist beam type suspension has a twist beam having an increased rigidity. Each of a pair of trailing arms has a front end pivotally mounted on a body of the vehicle and a rear end rotatably supporting a wheel. A twist beam extends between the trailing arms in a side-to-side direction of the vehicle. Opposite ends of the twist beam are connected to the respective trailing arms. The twist beam has a bent portion projecting upwardly in the center of the twist beam.
