The portable pool table device provides extreme portability by way of disassembly. The first structure includes: an air supply portion connected to a heat exchanger and supplying the heated air; an air distribution discharge portion discharging the heated air supplied from the air supply portion through a pair of discharging outlets in both sides of the prepreg; and at least one perforated plate symmetrically disposed in air passageways of the air distribution discharge portion. A fine delay is implemented upon the reference signal based upon a phase shift between the reference signal and a feedback signal. Instead, new parity is computed from the data to be written without the need of old parity or the storage server sends a command to a disk that stores parity. Further, P3HA resin foamed particles being composed of a resin composition that comprises an isocyanate compound, and a polymer, poly, having a recurring unit represented by the general formula :\u2014O\u2014CHR\u2014CH2\u2014CO\u2014\u2003\u2003 produced by a microorganism are provided.
