Title: Speed changing operation of agricultural vehicle
Inventor: ISHIMARU TAKEYUKI
IPC: B60W10/10
Filed: 1988-08-10
Abstract: PURPOSE:To prevent rotation direction of a speed changing and transmitting mechanism from being suddenly reversed and prevent a transmitter from being damaged in a short time by a method wherein a speed changing and transmitting mechanism is temporarily braked when the speed changing and transmitting mechanism is switched from forward to backward. CONSTITUTION:When a gear change lever 1 is swung from a neutral position to a forward position, a clutch 2 is disengaged by a clutch interlocking mechanism 4 as well as a speed changing and transmitting mechanism is changed to forward, and since the clutch 2 is engaged by the clutch interlocking mechanism 4, a vehicle travels forward. When the gear change lever 1 is swung from the forward position to backward, the clutch 2 is disengaged by the clutch interlocking mechanism 2 as the change lever 1 passes by the neutral position, and at the same time, since the speed changing and transmitting mechanism is braked by a brake interlocking mechanism 6, the vehicle is temporarily stopped. Then with the change lever located at a backward position, braking is canceled by the brake interlocking mechanism 6 as well as the clutch is engaged by the clutch interlocking mechanism to allow the vehicle to travel backward.

Title: Switching device of high frequency signal

IPC: H03K17/60
Filed: 1981-12-15
Abstract: PURPOSE:To improve the attenuating performance in a low frequency region when a power supply is on, by providing a high pass filter to at least one of the input and output terminal sides. CONSTITUTION:A switching transistor 6 is turned off when a power supply is turned off during which the power supply voltage is not applied to a switch control terminal. A low pass filter is formed with inductance elements 1 and 2 and a capacitor 5. At the same time, a high pass filter consisting of a capacitor 13 and an inductance element 14 is connected to the side of an input terminal 3. Then the matching of impedance is set properly between these high and low pass filters. Thus the attenuating performance is improved in a low frequency region and when the power supply is turned on without deteriorating the inserting loss when the power supply is turned off. The same effect is obtained by providing a high pass filter at the side of an output terminal 4.
