Filed: 1990-06-21
Abstract: PURPOSE:To suppress the troubles caused by the treatment given to the abnormality produced at storage of a passing control system by correcting a zone recorded before a system down into a passed zone based on the personal collation result only. CONSTITUTION:When a card reader 2a performs the open control of an entrance/exit door 1 with only the collation of the ID code of an ID code 4a at system down of a host computer 5a, the reader 2a leaves the system down record on the read card 4a. Then an unlock signal transmission command is sent to the reader 2a based on only the personal collation result of the ID code when the system downrecord is received from the reader 2a together with the ID code at system restoration of the computer 5a. Then the recorded zone where a passing requester precedently entered and left is updated after the requester entered and left without performing a zone check to decide whether or not a passing request is given from the zone where the requester entered and left precedently. As a result, a passing control operation set before the system down can be restored in a short time.

Title: Air suction and supply stopper
Inventor: TOOTSU MASAO
IPC: B65D33/16
Filed: 1990-06-21
Abstract: PURPOSE:To obtain a stopper which permits an easy sealing with an ordinary home appliance by a method wherein one of three layer parts is attached to one place of a receiving bag whose inner surface consists of heat-fusible film in such a manner that said one layer part is inserted into the receiving bag to some extent and the other two layer parts are extended outwardly of the receiving bag. CONSTITUTION:When a stopper 1 is mounted into a receiving bag 2, since the inner surface of the stopper 1 consists of a heat-fusible film 5, an inner protective material is provided in only a suction passage to protect the same from heat fusing. Since the inner surface of a two layer part 4 consists of a heat-fusible film 5 and the outer surface thereof consists of an heat-infusible film 6, the inner surface of the receiving bag alone can be easily heat sealed using an ordinary home iron after a bedding is received in the receiving bag 2 and the bag 2 is evacuated by a vacuum cleaner. If the receiving bag 2 is made of the same film as the two layer part 4, its sealing can be done in the same way as the two layer part 4 after an article is placed into the bag from its lower opening part.

Title: Port selecting system for input/output channel
Inventor: KIKUCHI TOSHINOBU
IPC: G06F13/14
Filed: 1990-06-25
Abstract: PURPOSE:To generate no delay caused by noncoincidence of an actuation pointer and the sequence of execution of a channel program due to a competition, and to improve the throughput of the whole system by storing a port address in order to generation of the actuation pointer of an input/output channel. CONSTITUTION:When a signal is inputted by an actuation pointer signal line (a), it is latched by a latch circuit 11 so that an overlap signal input of a port is not received. In such a state, a signal outputted from the circuit 11 is inputted to a port address generating circuit 12, and a port address of the signal line (a) is generated, and outputted to an FIFO 13. The FIFO 13 stores the port address in order of generation, and by using a data bus (c), a firmware in a peripheral controller calls the port address in order of generation of an actuation pointer of an input/output channel. Subsequently, the firmware in the peripheral controller sets a port address register 15, passes through a decoder circuit 14, and resets the latch circuit 11 of each port by using a reset signal line (b). In such a way, a signal by the signal line (a) expects newly an input.
