Methods and computer-readable mediums are provided for obtaining an optimally gated medical image. After that, a channel formation region, a source region, and a drain region can be formed with the use of the regions with different conductivities formed in the oxide semiconductor layer. The temperature detecting tip 17a of the temperature sensor 17 is arranged to face the inside of a circulation hole 12 of the housing 11 between a valve body 23 which constitutes the thermoelement assembly and a frame support part formed in the circulation hole 12 of the housing 11. The thin wet etch resistant layer may be a refractory dielectric material, or a dielectric such as HfOx, AlyOx, ZrOx, HfZrOx, and HfSiOx. The height of the fans is equal to that between the upper casing and the lower casing. An address of the neighboring private access point is identified, and a peer-to-peer network that includes the first private access point and the neighboring private access points is formed.
