Title: Superconductor jointed structure
Inventor: SAKAI HITOSHI
IPC: H01L39/02
Filed: 1990-03-29
Granted: 1996-03-19
Abstract: A jointed structure comprising at least two kinds of oxide superconductor having different melting points, higher melting point superconductor  and one lower melting point oxide  superconductor  being alternately  jointed.   In  this jointed structure, the lower melting oxide superconductor is used  as  a  joint  layer  for  the  higher  melting  oxide superconductors.  The jointed structure can be obtained by combining an Y-Ba-Cu-O oxide superconducting material and a Bi-Sr-Ca-Cu-O oxide superconducting material, or by combin-ing two Bi-Sr-Ca-Cu-O oxide  superconducting materials  of different compositions and accordingly of different melting points.  Large cylindrical structures used as, for example, a container for apparatus for biomagnetism measurement can be  produced by jointing two or  more divided cylindrical parts.  In this case, the technique of the jointed structure of the present invention can be applied for jointing of the divided  cylindrical  parts.   The  cylindrical  structure produced by jointing divided cylindrical parts according to the  present   invention  can  prevent  the  incoming  of geomagnetism,  thereby  enabling  reliable  measurement  of biomagnetism.

Abstract: A method by which redundant network interface modules (NIM)s interconnecting the communication buses of two local area networks communicate with one another at predetermined time intervals over the communication buses of both networks. One of the redundant pair of NIMs is designated as the primary and the other as the secondary. Contents of the information communicated between the NIMs over the communication bus of the first network includes the status of the transmitting NIMs ability to communicate with the second network and the information communicated between the NIMs over the communication bus of the second network includes the status of the transmitting NIM's ability to communicate with the first network. Based on the information exchanged, the failure of the NIMs to communicate as scheduled, and the internal status of each NIM as understood by that NIM, the NIMs decide when failover from the primary NIM to the secondary NIM occurs.

Granted: 1997-11-25
Abstract: A filtration apparatus for reducing contaminants in water used for household purposes and the like.  The apparatus includes a water container with a receiving reservoir mounted in the container.  The reservoir houses a filter and a first passage is formed at the top end of the reservoir for connecting the reservoir with the filter.  A second passage permits the flow of water from the first passage into contact with a barrier wall spaced away from the first passage.  A first chamber defined between the first passage and the barrier wall is connected by means of a third passage to a second chamber located on the other side of the barrier wall.  The filter also includes a bottom wall defining openings communicating with the second chamber. Filtering material is located within the first and second chambers so that water introduced into the receiving reservoir passes downwardly through the first passage, transversely through the second passage into the first chamber, upwardly through the first chamber, and then transversely through the third passage to the second chamber.  The water then travels downwardly through the second chamber and outwardly through the bottom wall openings for entering into the water container.
