Title: Timing signal generator
Inventor: SHINODA KAZUO
IPC: H04L7/00
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To generate lots of timing signals without increasing the circuit scale by allowing an output control section to generate a timing signal synchronously with a coincidence detection pulse so as only to provide one coincident detection section. SOLUTION: A memory 13 stores plural sets of position information designated as to a timewise position of a change point of a timing signal and output control information designating a signal change at an output terminal of the timing signal and at its change point. A coincidence detection section 14 compares the position information read from the memory 13 with a timer value and generates a coincidence detection pulse when they are coincident. An output control section 17 generates a designated timing signal based on the output control information read from the memory 13 and a coincidence detection pulse outputted from the coincidence detection section 14. When the coincidence detection section 14 outputs a coincidence detection pulse, an address counter section 15 generates an address signal designating an address of each information to be read next to the memory 13.

Title: Minipacket control system
Inventor: TAKADA OSAMU
Filed: 1987-12-18
Abstract: PURPOSE:To avoid the waste of lines that reception error is generated due to deficiency in a reception buffer when most of message is sent by allowing each reception station to ensure the reception buffer required for message reception in the initial stage of communication. CONSTITUTION:When a message processed as a capsule is sent while being divided into plural segments 4, a message length display identifier 2 is included in an information field of a FIRST minipacket. Then a reception station being the destination of the minipacket discriminates whether or not an idle buffer required for the reception of all segments exists and whether or not the reception of a message is enabled is informed to an outgoing station via an answer display identifier field. When the reception station can secure a buffer required for the message reception, the minipacket from one and same outgoing station arrived later is received one after another without reaching the rejection of reception due to the deficient buffer.
