Title: Laminated ceramic element and manufacture thereof
Inventor: NAGAYAMA HIROYUKI
IPC: H01L41/09
Filed: 1989-04-07
Abstract: PURPOSE:To prevent concentration of stress produced by uneven distortion induced during the course of an electrolytic process so as to obtain a highly durable ceramic element by forming empty parts at end sections of internal electrodes respectively put between each of a plurality of ceramic sheets. CONSTITUTION:After a plurality of ceramic sheets respectively provided with internal electrodes 24 is piled up so that parts 26 to be used for forming empty parts of the sheets 22 can be alter nately positioned on the left and right sides, the sheets 22 are press-contacted with each other by hot pressing and, after hot pressing, subjected to degreasing and firing processes at a prescribed temperature. Simultaneously, the electrodes 24 are baked so as to stick the electrodes 24 to the sheets 22. Even when the laminated body is fired, the sheets 22 directly above and below the parts 26 respectively formed of notched sections 28 do not stick to each other and empty parts 30 are formed at the parts 26. Then a pair of external electrodes 32 is formed so that the empty parts 30 at every other layer can be connected with each other and, at the same time, end sections of the internal electrodes between the empty parts 30 at every other layer can be connected with each other at every layer. As a result, occurrence of stress concentration can be prevented and a highly durable ceramic element can be obtained.

Filed: 1994-04-27
Abstract: PURPOSE:To shortren the execution time needed for maintaining the integrity of a data base by simplifying the relation among plural data items into such a relation where each of the data items keeps the integrity with a certain data item. CONSTITUTION:When a request is received from a user for display of the relation of reference integrity among the data items which are currently defined (101), a data base management system displays the relation of the defined reference integrity (102) and also displays the reference relation among plural keys chained together after simplifying it into such reference relation defined between a primary key and plural external keys (102). Therefor the user can obtain the decision information on the reference integrity constraint by those two types of display so that the reference relation is simpler when the user refers to 'KOKYAKU (customer) NO' than to 'KYAKU (customer) NO' by the primary key in regard of an external key 'KOKUYAKU BANGO (customer number)'. Thus the user can manage and operate more easily the reference integrity constraint.
