Abstract: Radio section 103 multiplies modulated transmission signals A to D respectively by a carrier with a frequency of fA, fB, fC or fD, thereby performs the frequency conversion, and outputs the resultant signals to switch 104. Switch 104 switches between frequency conversion sections fA to fD and between antennas A to D to connect, and timing control section 105 outputs a timing control signal to switching control section 107 at time intervals for which timer 106 is preset. Switching control section 107 controls the switching of switch 104 according to switching patterns which are preset in switching pattern storage section 108 and which are each indicative of a connection relationship between antennas A to D and frequency conversion sections fA to fD.

Abstract: In a receiving side apparatus 150, reception quality of receive data is measured by a reception quality measurement section 157, receive data errors are detected by an error detection section 156, and when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation section 158. In a transmitting side apparatus 100, when a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatus 150 is detected from a reception quality signal by a scheduling section 110, and data is retransmitted at that capacity. By this means it is possible to reduce the number of data retransmissions during transmission and reception, and to improve transmission efficiency.

The frame creation section 103 symbolizes a resource assignment signal and transmission data to create a frame, which it outputs to a spreading section 104.

Abstract: On a transmitter side, a known bit inserting section 101 inserts a known bit having a predetermined length at a predetermined position of transmitting data, and a tail bit inserting section 102 inserts a tail bit thereto so as to generate frame data. Then, a frame length detecting section 103 detects a length of frame data, a convolutional coding section 104 convolutional codes the frame data, and a dummy bit inserting section 105 inserts a dummy bit to the frame data so as to obtain a transmitting signal. On a receiver side, a decoding section 205 divides a receiving signal into a convolutional coded portion, including a head portion to a tail of a known bit, and a subsequent portion so as to perform decoding on a receiver side. Then, an unnecessary bit removing section 206 removes the known bit, the tail bit, and the dummy bit from the decoded data.

The upper surface of the dessiccant film is sealed with a moistureproof film. In producing a luminous pointer, these layers are laminated at a plurality of portions on the upper surface of a sheet which is to constitute pointer bodies, the pointer bodies are blanked along the outlines thereof by press working, and then the outside of the disiccant film is sealed with a moistureproof film. Alternatively, the outside of the desiccant film may be sealed with a moistureproof film before blanking the pointer bodies by press working.

Abstract: A three-handed clock has a single movement to rotationally drive the second, minute and hour hands. The rotary output of the movement is transmitted directly to the second hand and is transmitted through a transmission belt to the minute and hour hands. The use of the transmission belt eliminates the need for a gear train to drive the minute and hour hands thereby providing greater design flexibility and ease of assembly and maintenance.
