Abstract: The continuous casting device according to the present invention enables at least some of a plurality of hearths (3) to be converted between being hearths (13) used for titanium, which are used during the continuous casting of titanium ingots, and being hearths (23) used for titanium alloy, which are used during the continuous casting of titanium alloy ingots. The number of hearths (23) used for titanium alloy is greater than the number of hearths (13) used for titanium. Also, the total capacity of the hearths (23) used for titanium alloy is greater than the total capacity of the hearths (13) used for titanium. Thus, titanium ingots and titanium alloy ingots can each be continuously cast by means of a single piece of equipment.

Abstract: To reduce an uplink interference in a network with a first base station of a large output and a second base station of a small output. Detecting the interference, the second base station urges the first base station to hand over a terminal causing it to the second base station. Multiple base stations and one or more terminals exist in this system, each terminal connects with one base station, and a serving base station is changed according to a communication state of each terminal. If the different second base station other than the first base station to which the terminal connects detects a large interference, the second base station will multicast transmit information for urging handover to the base stations except itself. The base station having received the information specifies a terminal giving the interference to the second base station, and makes it to be handed over thereto.

Then, the ECU determines an abnormality regarding steering of the outboard engine main body based on a result of comparison between the gap amount and the first threshold value.

Abstract: Provided are a sulfated C-glycoside which is a novel compound serving as a precursor of chafuroside and chafuroside analogs; a method for efficiently producing the sulfated C-glycoside; and a method for efficiently producing chafuroside and chafuroside analogs using said sulfated C-glycoside. A sulfated C-glycoside represented by general formula (A1) or (B1) [wherein R1, R2 and R3 independently represent each a hydrogen atom or an OH group] is obtained by extracting tea leaves or tea tannins with water, a lower alcohol solvent having 1 to 3 carbon atoms or a liquid mixture comprising the same. Alternatively, the sulfated C-glycoside is produced by reacting a flavone C-glycoside such as isovitexin or vitexin with a sulfate group-introducing agent to thereby sulfate the flavone C-glycoside. By heating the sulfated C-glycoside thus obtained, chafuroside and chafuroside analogs are efficiently produced.
