Filed: 2021-09-29
Abstract: To derive a high temperature property evaluation index (a fusion starting temperature and a reduction rate at the start of fusion) of ore raw materials without conducting a test to measure the high temperature property evaluation index.SOLUTION: A high temperature property estimation method derives a high temperature property evaluation index of an ore raw material packed bed based on a pressure loss of the ore raw material packed bed due to softening shrinkage of an ore raw material. A reduction rate of the ore material is calculated based on a temperature of the ore material packed bed and conditions of a reducing gas supplied to the ore material packed bed. A shrinkage rate of the ore material packed bed is calculated based on the temperature of the ore material packed bed, a load on the ore material packed bed and the reduction rate of the ore material. The pressure loss in the ore material packed bed is calculated based on the shrinkage rate. The high temperature property evaluation index is the reduction rate of the ore raw material when the pressure loss reaches a specified value (a reduction rate at the start of fusion) or the temperature of the ore raw material packed bed when the pressure loss reaches a specified value (a fusion starting temperature).SELECTED DRAWING: Figure 2

Title: Game machine
IPC: A63F7/02
Filed: 2021-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of providing a player with a suggestive presentation having a high ingenuity. 
     SOLUTION: If information (a value) of a continuous determination information storage area of a read-ahead information No. zero (0) area is one (1), that is, if a final variation presentation is to be performed where a continuous notice presentation is set, a continuation avoidance flag in a read-ahead information No. 1 area is set on by the processing at S1134. In this way, when a next variation pattern command is received, shift processing is performed to a read-ahead information storage area 223g, and thereby the continuation avoidance flag in the read-ahead information No. zero (0) area is set on. Therefore, to the variation presentation for the next variation pattern command, a continuous notice performance flag always becomes not to be set on by the processing at S1131. Accordingly, it is possible to easily suppress continuous performances of the continuous notice presentation or a performance of a single notice presentation continuous to the continuous notice presentation by only setting on the continuation avoidance flag in the read-ahead information No. 1 area.
