Abstract: Polyamide pre-expanded particles of this disclosure have a peak temperature of a maximum endothermic peak of 150-275° C. on a DSC curve obtained while being heated from 30° C. to 280° C. at a heating rate of 10° C./min using a DSC. The width of the peak is 30-80° C. when a straight line approximating the DSC curve on a high-temperature side relative to the peak after an end of melting is used as a baseline. The width corresponds to a difference between an extrapolated melting start temperature which is a temperature at an intersection point between a tangent line at an inflection point of the peak on a low-temperature side and the baseline, and an extrapolated melting end temperature which is a temperature at an intersection point between a tangent line at an inflection point of the peak on a high-temperature side and the baseline.

Abstract: The present disclosure is directed to provide a method of producing polyamide resin foamable particles at a low foaming temperature. A method of producing polyamide resin foamable particles of the present disclosure include forming a foamable polyamide resin, into which a polar solvent and a foaming agent are made to be included, into a polyamide resin.

Abstract: The present disclosure is directed to provide polyamide-based resin pre-expanded particles which can serve as a raw material of a polyamide-based resin foam shaped product having an excellent mechanical strength. Polyamide-based resin pre-expanded particles of the present disclosure contain a polyamide-based resin. The polyamide-based resin pre-expanded particles have an expansion ratio of 1.0 or more, wherein the expansion ratio is a ratio (?1/?2) of a density ?1 (g/cm3) to a density ?2 (g/cm3) after being pressurized with air at 0.9 MPa and then heated for 30 seconds with saturated steam at a temperature higher than a thermal fusion temperature by 5° C.

Abstract: A standby process controller includes a mode control unit which is on standby without starting a standby-in process when a power-off signal is detected, stops audio and image output of an operation execution unit, sets a pre-standby mode to an electronic device so as to allow a standby-in process to be started and ended at any time, and releases the setting of the pre-standby mode when a power-on signal is detected, and a standby-in process start control unit which starts the standby-in process when a predetermined time elapses since the pre-standby mode is set. A standby-out process can be immediately performed in a case where a user performs a power-on operation within several seconds after a power-off operation is performed.
