  • Patent number: 6011912
    Abstract: In an automatic routing method for layout design, the present invention reduces wastful detours or bends of the routing paths, so that it also reduces non-completed paths, that cannot be completed without rip-up and rerouting. All nets are provisionally routed in such a manner as to allow more facilitated evasion of collision such as shorting between nets (step 15). The net order is then set (step 16). If collision between nets is found, the processing order is changed so that a net which is judged to allow for more facilitated evasion of collision will be finalized later. The routing paths are then finalized net by net (steps 17 to 20). The shape of the colliding path, for example, is used as a criterion for judging ease in evasion.

  • Patent number: 5072155
    Abstract: The invention provides a rare gas discharge fluorescent lamp device which is long in life and high in brightness and efficiency. The lamp device comprises a rare gas discharge fluorescent lamp including a glass bulb having xenon, argon or krypton gas enclosed therein, a fluorescent layer formed on an inner face of the bulb, and a pair of electrodes located at the opposite ends of the bulb. A pulse-like voltage wherein the ratio of an energization period with respect to one cycle is higher than 5% but lower than 70% (xenon or krypton gas) or 80% (argon gas) and the energization period is shorter than 150 .mu.sec is applied between the electrodes of the lamp. Such pulse-like voltage is produced from a circuit including a dc power source, a pulse signal source, and a switching element for controlling application of a voltage of the dc power source or such voltage boosted by a boosting transformer or a resonance circuit.

  • Patent number: 4544862
    Abstract: A lighting circuit for an electric discharge lamp according to the present invention is constructed in such a way that a switching device is provided at an output terminal of a high frequency inverter which produces a substantially sinusoidal output voltage, and that, by controlling this switching device, an output to the low pressure electric discharge lamp is stopped at the rising part of the abovementioned output voltage in its half cycle, while the output is supplied to the low pressure electric discharge lamp at the voltage level in the vicinity of the maximum instantaneous value thereof. By use of the high frequency inverter of a smaller capacity and less radio noise than those in the conventional device, the operating efficiency of the low pressure electric discharge lamp can be increased.
