    摘要： The invention relates to a control apparatus for controlling a solenoid valve that functions to displace one of an intake valve or an exhaust valve of an internal combustion engine. The object of the invention is to adjust, when a valve element connected to the solenoid valve is displaced between a valve-open position and a valve-closed position, the magnitude of an electromagnetic force displacing the valve element, to a controlled value based on a pressure acting on the valve element. The solenoid valve displaces the valve element (40) by a cooperation of resilient forces of an upper spring (104) and a lower spring (106) and electromagnetic forces of an upper coil (98) and a lower coil (100). In the control apparatus, a pressure acting on the valve element (40) is detected directly or indirectly. When the valve element is displaced from one of the valve-open position and the valve-closed position to the other position, the magnitude of an electromagnetic force to displace the valve element (40) to the other position is adjusted to a controlled value based on the valve-element pressure detected.

    摘要： A noise elimination circuit for eliminating noise signals from data given by a binary form includes a modulo in up/down counter having a first input for receiving binary data, a second input for receiving clock pulses and output for producing a counted signal. The counter is effected to count up in response to the clock pulses when the binary data is a HIGH, and to count down in response to said clock pulses when the binary data is a LOW. A decoder is provided which has inputs for receiving the counted signal, a first output for producing an indication signal when the counted signal corresponds to a first predetermined number i, and a second output for producing an indication signal when the counted signal corresponds to a second predetermined number j, in which i is equal to or greater than zero, j is greater than i and n is equal to or greater than j. A flip-flop is provided which has a reset terminal connected to the first output of the decoder, a set terminal connected to the second output of the decoder and an output for producing a data with noise signals being eliminated.

    摘要： Disclosed here are D-type flipflops cascaded in a semicustom LSI such as a standard cell or a gate array. Clock signals supplied to each of the flipflops have phases different from each other due to clock skew. A signal indicative of a data signal holding in the flipflop in one stage is applied to the flipflop in the preceding stage. The flipflop in the preceding stage is responsive to the applied signal for allowing a data signal held in a master latch to be transmitted to a slave latch. As a result, the passing through of data which might be possibly caused by the clock skew can be prevented. In other words, the passing of a data signal through two flipflops during one clock cycle can be prevented.
