Title: Process for operating coke oven
Inventor: MIYAKE TATSURO
IPC: C10B41/00
Filed: 2000-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a process for operating coke ovens which enables an increased coke production without damaging furnace wall bricks. SOLUTION: A database comprising operation data, blend coal data, coke data, repair data and damage data produced for each carbonization chamber is analyzed to construct an extrusion force-generation model wherein the extrusion force generated in each carbonization chamber under a certain condition is mathematized. The operation condition for each carbonization chamber is set based on this extrusion force-generation model. If the current extrusion force is smaller than that damaging the furnace wall bricks, the amount of coals charged in the oven will be increased under the extrusion force-generation model until the extrusion force which has been recalculated using the extrusion force-generation model approximates the extrusion force damaging the furnace wall bricks.  By reflecting the amount of coals charged under the extrusion force-generation model in the amount of coals charged in the actual oven, the coke production may be increased without damaging the furnace wall bricks.

Title: Semiconductor device
Inventor: YANO MORICHIKA
IPC: H01L21/8246
Filed: 2000-10-18
Abstract: PROBLEM TO BE SOLVED: To eliminate deterioration of a ferroelectric film. SOLUTION: A ferroelectric thin film 30, constituting a ferroelectric capacitor 33 of a ferroelectric memory element, is formed out of an SBT thin film, having added Zr elements as the elements for feeding holes. Therefore, the Zr elements of IV-B group elements generate the holes by their substitutions for Bi elements in the SBT thin film. As a result, even if hydrogen which could not be prevented with a diffusion barrier 32, when the ferroelectric memory element is subjected to hydrogen sintering processing bonds with oxygen contained in the SBT thin film to form oxygen vacancies, electrons generated from the oxygen vacancies are so neutralized by the holes as to very much reduce the leakage current of the ferroelectric memory element.  Also, the diffusion of the oxygen ions and their removals from the SBT thin film are markedly suppressed by the electrical coupling of holes with the oxygen ions. Thus, even if hydrogen diffuse to the ferroelectric thin film 30 when the hydrogen sintering processing is being carried out the ferroelectric thin film 30 will not deteriorate.
