Abstract: A vibration-isolating device for a steering wheel of a travelling working vehicle equipped with a wheel steering mechanism includes a first steering shaft (32) that transmits rotational displacement, the first steering shaft being operatively connected to the steering wheel (7); a second steering shaft (33) that transmits rotational displacement, the second steering shaft being operatively connected to the wheel steering mechanism (P, 23); and a vibration-isolating connecting mechanism (31) that operatively connects the first steering shaft (32) and the second steering shaft (33) to each other so that rotational displacement can be transmitted. When the angles of rotational displacement of the first steering shaft (32) and the second steering shaft (33) are within ranges of rotation angles for linearly driving the vehicle, rotational displacement cannot be transmitted between the first steering shaft (32) and the second steering shaft (33).

Abstract: A packet communication apparatus processes consecutively transmitted fixed-length packets. The apparatus includes a storage circuit, a first processing circuit which accesses the storage circuit for processing data obtained from each of the packets, and a second processing circuit which accesses the storage circuit for processing data stored in the storage circuit. The apparatus further includes an allocation circuit for executing access time allocation with respect to a packet processing time allowed for processing each of the packets. Specifically, the allocation circuit allocates a first time of the packet processing time to the first processing circuit for accessing the storage circuit and a second time of the packet processing time to the second processing circuit for accessing the storage circuit. The first time and the second time are prevented from overlapping with each other.
