Title: Packet retransmission device
Inventor: RICHIYAADO PII EJIYATSUKU
IPC: H04L1/18
Filed: 1994-11-30
Abstract: PURPOSE: To improve the efficiency of a transmission line by allowing a transmitter to transmit a data packet by relating a sequence number and a transmission order number to the data packet and to execute repeated transmission until a status control message is obtained from a receiver. CONSTITUTION: A transmitter 100 has a transmission list buffer 130 consisting of plural continuous RAM memory locations, and a transmission controller 120 corresponding to a range of numbers generated by a generator 125 stores the sequence numbers of packets to be transmitted in relation to numbers generated by a transmitting number generator 145 in the butter 130. These numbers indicate the order of all data packets (including also data packets to be retransmitted) transmitted from the controller 120. When traffic is heavily loaded, the receiver transmits a partial status control message added to each information packet instead of the whole status control message. Thus the receiver will not apply excess load on a reverse channel band to the transmitter.

IPC: C04B35/80
Filed: 1988-12-20
Abstract: PURPOSE:To lower production cost by forming a calcium silicate matrix of tobermorite adding the specified amount of a specified filler thereto in the subject material made of a calcium silicate-based molded body wherein carbon fiber is dispersed in the above-mentioned matrix. CONSTITUTION:The constitutional material for a low-m.p. metal casting device is made of a calcium silicate-based molded body wherein carbon fiber, 10-20wt.% fibrous wallastonite and 20-30wt.% crystalline alumina are dispersed in an inexpensive tobermorite-based calcium silicate matrix. Large amounts of water are contained in the structure of tobermorite-based calcium silicate and heat resistance is low and therefore shrinkage percentage is made large when it is heated at >=600 deg.C. In the above-mentioned constitutional material, the relative ratio of tobermorite-base calcium silicate is lowered by addition of the above- mentioned fillers and the amount of steam generated during usage is lowered and heat shrinkage percentage is made small. Therefore the need for previously heat-treating the constitutional material at 500-600 deg.C is eliminated and therefore carbon fiber can be utilized.
