Title: Repeating communication control system
Inventor: HOBO YOSHIHIRO
IPC: H04N1/00
Filed: 1987-11-18
Abstract: PURPOSE:To disperse a line service rate without concentrating communication requests upon the line of a master station by concentrating a repeated result report by a polling system according to the communication control of the master station itself. CONSTITUTION:When the CPU 15 of the master station drives an NCU 16, and sends a call signal to a first repeater station 3, and confirms a reception finish report, and disconnects the line, it sets a time corresponding to the number of allotting stations having requested the repeater station, in a timer circuit 14. When communication between a final end station (m) requested to repeat by the first repeater station and the repeater station is finished, the first repeater station edits a communicated result with respective end station as one page, at least, of repeated result report information, and stores it in a memory 22 as a polling draft. When the set time comes, the master station sends automatically a call repeated result report transmission request to the first repeater station.

Title: Erasable non-volatile storage cell, array connection switching element of programmable logicale device, and programmable logical device
Inventor: BURUUSU ANDORIYUU DOIRU
IPC: G11C16/04
Filed: 1990-10-31
Abstract: PURPOSE: To shorten the switching time of a programmable logical unit by providing floating gate transistors, a read transistor and a write transistor in an EEPROM cell and preventing the occurrence of an undesired capacitive load. CONSTITUTION: Only the half of the floating gate transistors 66 and 68 is connected to a product output signal line 62. That is because only either selection transistors 74 or 76 are turned on for respective columns. Since 74 and 76 do not need to deal with programming high voltage, design can be executed by using the shortest channel length element. The capacitive loads of 74 and 76 are considerably smaller than the capacitive loads of 66 and 68. That makes the capacitive load of the product output signal line 62 to be a minimum. Since signals ROW and ROWB are not driven to super voltage, a CMOS circuit can be used for driving both signals. The voltage amplitude improves a signal margin and accelerates switching time.
