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.

摘要： 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.

摘要： An overflow suppression technique that is effective for avoiding degradation in image quality is provided. A fundamental waveform and detail is extracted out of an input RGB signal. A suppression gain generation unit 614 generates a suppression gain from the extracted fundamental waveform. Multipliers 612a and 612b multiply the detail and the fundamental waveform by the generated suppression gain, respectively. Then, an adder 626 combines them together for a mixed output. Alternatively, equalization processing is performed as follows. A low frequency component fundamental waveform is obtained as a result of the passing of an input RGB signal through a low pass filter 622. A suppression gain is generated from the low frequency component fundamental waveform. Then, the input itself is multiplied by the suppression gain to obtain an output.

摘要： 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.

摘要： 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.
