Abstract: PURPOSE:To increment a frequency division ratio by one with simple circuit constitution by substantially interrupting a variable frequency division output of a prescribed stage number of 2nd and succeeding stages attended with an AND output between a 1st logical level signal and a signal commanding to increment the frequency division ratio by one. CONSTITUTION:Variable frequency dividers 5, 6, 7, 8,... acting like 1/2 or 1/3 frequency dividers selectively are connected in cascade. Moreover, a NOR gate 1 is provided in place of a 1st stage inverter and an AND gate 10 controlling the pass of an output mod1 of a 2nd stage variable frequency divider 6 is provided. Then an output of the AND gate 10 is used as one input to an OR gate 11, and when a Q output of each variable frequency divider is all logic 0 and both a +1 signal and a setting input D0 are both logical 1, the variable frequency divider 5 act like 1/2 frequency dividers. When either the +1 signal or the setting input D0 is logical 1 and a Q output of the variable frequency dividers 6, 7, 8 is '000', the variable frequency divider 5 acts like a 1/3 frequency divider.

Filed: 1989-09-12
Abstract: PURPOSE:To contrive the improvement of an output and the reduction of exhaust noise with uniform charging efficiency in right and left banks by controlling exhaust energy in an exhaust front tube of at least the one bank so as to obtain a uniform exhaust flow speed. CONSTITUTION:Physical quantity detecting means 7, 8, constituted of full pressure pickups and static pressure pickups, are respectively mounted to exhaust manifolds 2, 3. Here in a control unit 18, an exhaust flow speed in each bank is calculated being based on outputs of the physical quantity detecting means 7, 8 in accordance with a program stored in a memory in the inside. A control value of exhaust control, in which the exhaust flow speed is uniformly generated when an exhaust valve is closed, is calculated with a control signal output to step motors 15, 16. Thus because control valves 13, 14 are driven by the step motors 15, 16 being based on the control signal, resonators 11, 12 are open close-controlled to control exhaust energy in exhaust front tubes 6a, 6b. Accordingly, charging efficiency in right and left banks is made uniform.
