摘要： An exhaust gas recirculation device for an internal combustion engine has a filter for trapping particulates in a recirculation gas, which is arranged in a recirculation gas route, and a device for generating a reverse air flow in which a pure gas flow for the reverse air flow passing through said filter in a reverse direction with respect to a recirculation gas flowing direction in the filter is generated. In the exhaust gas circulation device, the trapped gases are discharged out of the filter by the reverse air flow and are not returned into the internal combustion engine due to an engine exhaust pressure.

摘要： A reference voltage generator is composed of a first constant-voltage generator consisting of three p-type MOS transistors for generating a first reference voltage Vref for use in the normal operation, which is independent of an external power-supply voltage VCC and of a second constant-voltage generator consisting of two p-type MOS transistors and one n-type MOS transistor for generating a second reference voltage Vrefbi for use in a burn-in acceleration test, which is dependent on VCC. The output of each of the constant-voltage generators is feedbacked to the other constant-voltage generator as its input. Two differential amplifiers and two output drivers output, as an internal reduced voltage Vint, the higher one of Vref and Vrefbi which are outputted from the reference voltage generator. Since Vint is generated based on the two outputs Vref and Vrefbi which are outputted from the single reference voltage generator and which are related to each other, the power consumption and layout area of an internal reduced-voltage generator, which is suitable for the burn-in, can be reduced.

摘要： In a driver circuit for driving a pair of data lines, the amplitude of a differential input signal is reduced from 2.5 V to 0.6 V, which is smaller than a conventional lower-limit source voltage (approximately 1.5 V). The amplitude of the differential signal transmitted through the pair of data lines is amplified to 2.5 V by an amplifying circuit and the resulting signal is then latched by a latch circuit. After the latching by the latch circuit, the operation of the amplifying circuit is halted. The driver circuit is constituted solely by a plurality of NMOS transistors so as not to increase a leakage current flowing in the off state. Here, the threshold voltage of the NMOS transistor positioned on the ground side is reduced to a conventional lower-limit value (0.3 V to 0.6 V), while the threshold voltage of the NMOS transistor on the power-source side to a value lower than the above lower-limit value (0 V to 0.3 V), thereby enhancing a driving force of the NMOS transistor on the power-source side.

摘要： A ceramic honeycomb catalyst includes a thin-walled honeycomb structural body (10) and a catalytic substance carried by the honeycomb structural body (10). The honeycomb structural body (10) has a number of longitudinally extending flow passages (13) defined by an outer peripheral wall (11) and partition walls (12) with a reduced thickness (t). The honeycomb structural body (10) satisfies particular relationships between the partition wall thickness (t) and the open frontal area (OFA) or bulk density (G). Notwithstanding the thin-walled partition walls, the honeycomb structural body (10) has practically satisfactory compressive strength characteristics. The catalyst comprising the honeycomb structural body (10) has reduced pressure loss and heat capacity.

摘要： In a substrate potential generator, a substrate potential is supplied by a substrate potential supplier controlled by a substrate potential detector. The substrate potential detector sends a setting signal having a hysteresis characteristic relative to the substrate potential. That is, the setting signal is higher when the substrate potential supplier is stopped than when the substrate potential supplier is activated or when negative charges are injected into the substrate potential. Thus, the operation of the substrate potential supplier is stopped after the substrate potential becomes lower than the lower setting potential when the substrate potential supplier is activated, while the operation of the substrate potential supplier is started after the substrate potential becomes higher than the upper setting potential after the operation of the substrate potential supplier is stopped. Therefore, the starting and stopping of the substrate potential supplier is not repeated so frequently, so that the dissipating charge and discharge currents accompanied with the starting and stopping will not be enhanced wastefully.

摘要翻译： 在衬底电位发生器中，由衬底电位检测器控制的衬底电位供给器提供衬底电位。 衬底电位检测器发送具有相对于衬底电位的滞后特性的设置信号。 也就是说，当衬底电位供给器停止时，设置信号比衬底电位供应器被激活时或当负电荷注入衬底电位时更高。 因此，在基板电位供给器被激活之后，在基板电位变得低于基板电位供给器的下限设定电位之后，基板电位供给器的动作停止，同时基板电位供给器的动作在基板电位变得高于上限值之后开始 在停止基板电位供给器的操作之后的潜力。 因此，不会如此频繁地重复基板电位供给器的启动和停止，从而不会浪费地增加伴随启动和停止的耗散充放电电流。
