The present invention is to prevent melted sealant from flowing into the interior of a case of an electronic component package that is provided with a shielding electrode on the inner surface of the case, fill a through-hole with the sealant with reliability, and perform vacuum airtight sealing. The apparatus samples the ion current by carrying out AD conversion at every constant time period. Methods provided include producing a soybean plant by crossing soybean variety XB32AR11 with another soybean plant, methods for introgressing a transgenic trait, a mutant trait, andor a native trait into soybean variety XB32AR11, methods for producing other soybean varieties or plant parts derived from soybean variety XB32AR11, and methods of characterizing soybean variety XB32AR11. Accordingly, control is conducted so that the regularly required surplus pressure can be reduced to a minimum required amount.
