Abstract: PURPOSE:To prevent the deterioration of the operation performance due to the variation of torque when an exhaust system is switched, by setting the selected revolution speed of the exhaust system to the cross point revolution speed or less in the output characteristic which varies according to the length of a suction pipe and selecting the exhaust and intake systems. CONSTITUTION:The respective opening and closing valves 11 and 12 of the longer and shorter suction pipes 10a and 10b are opening/closing-driven by an actuator 13, and selectively used. The sectional surface of each tail tube 15, 16 connected with an exhaust pipe 14 is varied by the opening/closing drive of an opening/closing valve 17 installed into one of the tubes by an actuator 18. In this case, the drive of each actuator 13, 18 is controlled by a control circuit 20 into which the signals of a throttle switch and a crank angle sensor are input through an engine control circuit 19. When the engine is in low speed operation, the length of the suction pipe 10 is made longer, and in the high speed revolution, the suction pipe 10 is made shorter at the cross point revolution speed or less in the output characteristic which is varied according to the length of the suction pipe 10.

Inventor: ATOKAWA SUKEYUKI
IPC: H01P7/04
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce current consumption and to decrease number of part items for miniaturizing a frequency variable resonance circuit, a frequency variable filter, and antenna-sharing device and a communication device respectively by connecting electrically the cathode side of a diode to one of both ends of a resonator with the other end grounded, grounding the anode side of the diode via a coil and a capacitor and connecting electrically a voltage control terminal to an intermediate connection point set between the coil and the capacitor to control the voltage of the diode. SOLUTION: When no voltage is applied to a voltage control terminal CONT1 and the control voltage is set at 0 V, PIN diodes D2 and D3 are turned off. Under these conditions, band variable coils L2 and L3 are electrically separated from the resonators 2 and 3, and accordingly the resonance frequency is lowered. If the reception wave waiting frequency is set on a low channel, an antenna sharing device 31 sets the control voltage of voltage control terminals CONT1 and CONT2 at 0 V to secure a reception wave waiting state. The PIN diodes are kept in OFF states during the reception wave waiting state. Thereby no power is consumed during the reception wave waiting state.
