Title: Complementary buffer circuit
Inventor: HAYAKAWA SEIKO
IPC: H03K17/687
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a complementary buffer circuit with a simple circuit configuration that can prevent a through-current from flowing through between a power supply terminal and a ground terminal. SOLUTION: The complementary buffer circuit is provided with 1st and 2nd logic setting circuits 1, 2 that output complementary output signals in response to logics of complementary input signals A, B, a cross coupled load circuit 3 that keeps a high level to the other complementary output signal when the one of the complementary output signals is at a low level, 1st and 2nd keeper circuits 4, 5 that can keep a low level to the complementary output signals (t), and 1st and 2nd delay circuits 6, 7 that delay the complementary input signals. When a rising edge of either of the complementary input signals A, B is earlier in terms of timing than a falling edge of the other, the logic of the complementary output signals is inverted when the one rises and no through-current flows through between the power terminal and the ground terminal, resulting that the logic of the complementary output signals can quickly be confirmed while reducing the power consumption.

Title: Controller for motorcycle
Inventor: KATO TATSUNORI
IPC: B62H1/02
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To improve the operatability while improving the safety in projecting a stand of a motorcycle. SOLUTION: The output of an engine of the motorcycle is transmitted to a rear wheel through an electromagnetic clutch 25 and a continuously variable transmission 28. When the stand for supporting the motorcycle during parking is not housed in a car body side, the electromagnetic clutch 25 is disengaged to prevent the output of the engine from being transmitted to the rear wheel 43. Whereby, the rear wheel can be prevented from being driven even when a driver operates an accelerator for racing in a state that the stand is not housed in the car body side, which improves the safety of the motorcycle. Further, an engine can be started for racing in safety in a state that the car body is supported by a main stand 38, and the operatability can be improved.
