摘要： A multi-directional multiple access communication system includes a master station and subscriber stations including a specific subscriber station. The system performs communications using a demand assignment scheme in which time slots are assigned between the subscriber and master stations only when a call is generated by a subscriber station. The master station includes a first transmission/reception section, a rate conversion circuit, a second transmission/reception section, a memory, and a distribution circuit. The first transmission/reception section performs multi-directional multiple access communication of a time slot signal with each subscriber station excluding the specific subscriber station via a first transmission path. The rate conversion circuit converts a time slot signal into a signal having a transmission rate lower than that of the first transmission path. The second transmission/reception section transmits the converted signal to the specific subscriber station via a second transmission path. The memory stores the first maximum number of time slots which can be transmitted via the second transmission path. The distribution circuit distributes a signal corresponding to the second transmission path within the first maximum number of time slots which is set in the memory.

摘要： A radial tire for heavy load vehicles such as light trucks, trucks, busses, super-large type construction vehicles, etc. is disclosed. The radial tire comprises a carcass ply composed of a steel cord ply and wound around a bead core from the inside toward the outside thereof to form a turn-up portion. The upper end of the turn-up portion is upwardly extended to a position located between a point passing over the maximum width point of the carcass ply expanded by applying an internal pressure to the tire and a point where a normal drawn perpendicular from a hump to the carcass ply crosses with the carcass ply. The turn-up portion of the carcass ply is separated from the carcass ply by means of a soft rubber layer composed of rubber having a Shore A hardness which is smaller than a Shore A hardness of a coating rubber of the carcass ply and a 300% modulus of elasticity which is 50% to 85% of a 300% modulus of elasticity of the coating rubber of the carcass ply.

摘要： In a demand assignment TDMA communication system, a central station transmits a frame sync and a polling signal at periodic intervals to terminal stations to elicit a response therefrom. Each terminal station transmits a test signal in response to reception of the frame sync. The central station or a repeater station detects the strength of the test signals received by a regular-channel receiver and a spare-channel receiver and determines if each of the receivers is operating normally or abnormally. The response received by the regular-channel receiver is supplied to a utilization circuit when this receiver is determined as operating normally and the response received by the spare-channel receiver is supplied instead to the utilization circuit when the regular-channel receiver is determined as operating abnormally while the spare-channel receiver is determined as operating normally.
