Title: Packet transfer system
Inventor: KATO JUNICHI
IPC: H04L47/43
Filed: 1988-12-20
Abstract: PURPOSE:To considerably reduce the lowering of transfer efficiency due to a network header by adding only one network header to plural packets in a packet switching network and editing a repeater packet. CONSTITUTION:When a packet P is transmitted to another packet switchboard 1, a repeater packet editing means 100 connects together with other packets P...P which are standing by for transmission to a same calling station, adds one network header NH, and edits a repeater packet NP. Further, it provides identification information x...x to show the location of respective packets P...P in the repeater packet NP for the network header NH and transmits to the calling station. When a repeater packet separation means 200 receives the repeater packet NP for its own station from another packet switchboard 1, it separates the respective packets P...P to be contained in the repeater packet NP based on the packet identification information x...x to be contained in the network header NH, and distributes to each destination.

Title: Actuation system at specified time
Inventor: TAKADA JUICHI
IPC: H04M3/42
Filed: 1988-12-20
Abstract: PURPOSE:To cancel the registration of specified time actuation service after attaining expected purpose by a registered subscriber by providing a cancellation code registration means to stop the execution of a processing with a specified time actuation means and a maximum repetition times registration means. CONSTITUTION:A cancellation code registration means 200 being provided in an exchange 1 stops the execution of the processing with a specified time actuation means 100 by inputting the cancellation code by a subscriber 2 after registering the cancellation code to be inputted with a previously specified registration operation by the subscriber 2. A maximum repetition times registration means 300 repeatedly executes the processing of maximum actuation times to the means 100 as long as the means 200 receiving the cancellation code does not stop the processing after the subscriber 2 registers the maximum repetition times to be inputted with a previously specified registration operation. Consequently, the specified time actuation service is executed within the range of the previously registered maximum actuation times until the previously registered cancellation code is inputted after the registered subscriber 2 attains the expected purpose, and a concern about the specified time actuation service cancellation before the subscriber attains the expected purpose can be eliminated.

Title: Microprocessor with built-in cache memory
Inventor: SATOU YOSHIKUNI
IPC: G06F12/08
Filed: 1989-12-15
Abstract: PURPOSE:To invalidate only data sent and arrived when erroneous data was sent and arrived, and to minimize the fall of performance by determining whether an effective bit is to be made effective or not according to the calculated result of a redundant information calculation circuit. CONSTITUTION:A parity control circuit 212 calculates a syndrome form the sent data and parity information sent from a parity latch 213 through an internal parity bus 232, and decides whether the sent data is correct or not. When the sent data is decided to be ineffective, an effective bit control circuit 223 does not make one of the corresponding bits of a cache memory active. Thus, since the erroneous data need not be stored when the erroneous data is sent and arrives because of a noise, etc., during the transfer of an instruction or the data, or when the contents of a memory is broken because of the soft error of the memory, the fall of the performance is made small.
