    摘要： A semiconductor integrated circuit includes a bias voltage regulation circuit having variable resistors which are provided between voltage output circuits of higher and lower potential sides and changes corresponding to a specified condition such as V.sub.CC and a temperature. The variable resistors and bias voltage output circuits form a V.sub.CC divider, and the variable resistors properly regulate a bias voltage supplied to an oscillation circuit corresponding to each of the specified conditions. Accordingly, if the oscillation circuit is used in an automatic refresh circuit of a PSRAM, an increase of a refresh operation frequency is suppressed regardless of an increase in V.sub.CC. Since a temperature depending variable resistor causes a resistance value to be reduced by the predetermined characteristics against the temperature increase, it is possible to set an oscillation frequency to provide a desired pause for guarantee of circuit operation. It is possible to provide a ring oscillator having a low dependency of the oscillation frequency on a power source voltage and a temperature characteristic, thereby decreasing its current consumption.

    摘要： An engine 1 includes a variable valve mechanism 18 capable of switching a valve characteristic to a first valve characteristic according to which at least one of an operation of pre-opening an intake valve 14 during an exhaust stroke prior to a valve opening time in an intake stroke and an operation of re-opening an exhaust valve 15 during the intake stroke subsequently to the opening/closing thereof during the exhaust stroke is performed, and to a second valve characteristic according to which neither the pre-opening of the intake valve 14 nor the re-opening of the exhaust valve 15 is performed. In the engine 1, when the valve characteristic is the first valve characteristic, if the presence of a request for switching to the second valve characteristic resulting from an increase in engine load is detected, a pressure reducing operation for reducing the pressure in an exhaust passage 40 of the engine 1 is performed (e.g., a regulate valve 68 is opened). This allows, when the valve characteristic is switched from the first valve characteristic to the second valve characteristic as a result of an increase in engine load, the amount of fresh air charged into a cylinder 2 to be increased at the earliest possible time.
