Title: Duplex system
Inventor: FUJIYOSHI NOBUKI
IPC: G06F13/00
Filed: 1994-05-18
Abstract: PURPOSE:To obtain a duplex system wherein an in-operation system device can secure a SCSI bus even when both two devices try to secure the SCSI bus by providing a monitor means which makes a request to set a SCSI ID again and requests the in-operation system device to perform switching to the stand-by system. CONSTITUTION:A monitor task 3, which have detected abnormality, requests a device 1 to stop and a SCSI control part 21 to set a SCSI ID again. The device 1 receiving the request to stop stops its function. The SCSI control part 21 having received the request to set the SCSI ID again sets (validates) the SCSI ID again and the device is reactuated as the in-operation system. Thus, if the in-operation system device 1 becomes abnormal, the ID of the stand-by system device 2 is changed into an ID whose access instruction is effective and the ID of the in-operation system device 1 is changed into an ID whose access instruction is not effective. Therefore, even when the in-operation system device 1 is accessed by mistake, its ID is not effective, so the stand-by device 2 can secure the SCSI bus and its operation can be guaranteed.

Abstract: PURPOSE:To carry out in a short time in safe and simple ways by piercing several pieces of needles installed onto a ring without using the manual suturing operation between the organ tissue and a digestive tract. CONSTITUTION:A ring 1 having a piercing needle which is connected with a talking-out string is introduced into the tube bore of an intestine tract, and a handle 3 is inserted from a hole 17 drilled on the intestine wall on the opposite side to an intestine tract anastomosis hole 16, and the handle is fitted with the ring having the piercing needle. The piercing needle is adjusted to a port a hepatica part to be sutured, and inserted into the peripheral wall of the anastomosis surface of the intestine tract and lever, observing the mark of the handle. Since, in this case, the length of the needle in the direction towards a large vein such as lever tract and portal vein is reduced, these parts can be prevented from being damaged. After the needle of the ring is pierced into the peripheral wall of the anastomosis holes of the both, the ring is left as it is, and the handle is removed from the ring. The handle insertion hole 17 of the intestine tract is suture-closed. After the completion of anastomosis after one - two weeks, the string 6 projecting from an intestine opened port part 14 which projects outside skin is pulled out to take out the ring. Therefore, no foreign material is left in the inner surface of the anastomosis part.
