Abstract: A method for producing a polytetrafluoroethylene particle, which includes subjecting tetrafluoroethylene to suspension polymerization in an aqueous medium to prepare a suspension-polymerized particle of polytetrafluoroethylene, washing and then crushing the suspension-polymerized particle or crushing the suspension-polymerized particle with washing to prepare a crushed particle, dehydrating the crushed particle to prepare a crushed particle having a water content of 40% by mass or less, and subjecting the dehydrated crushed particle to heat treatment to produce a polytetrafluoroethylene particle.

Abstract: A method for producing a polytetrafluoroethylene powder, which includes subjecting tetrafluoroethylene to suspension polymerization in an aqueous medium to prepare a suspension-polymerized particle of non melt-processible polytetrafluoroethylene, drying the suspension-polymerized particle to prepare a dry particle, subjecting the dry particle to fluorine radical treatment to prepare a fluorine radical-treated particle, and crushing the fluorine radical-treated particle to produce a polytetrafluoroethylene powder. Also disclosed is a polytetrafluoroethylene formed article obtained by forming the polytetrafluoroethylene powder, as well as a polytetrafluoroethylene compression-molded article obtained by compression molding the polytetrafluoroethylene powder.

Abstract: An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

Abstract: A vehicle side structure includes a pillar which extends vertically at a side of a vehicle, a service hole which is provided at a lower portion of the pillar, a cover that closes the service hole, and a seal which is provided around the full periphery of the cover to seal between a perimeter of the cover and a perimeter of the service hole.

Abstract: A vehicle air conditioning duct for introducing air from an air conditioner to a rear seat includes: an air intake section; a curved section arranged on a side face of a floor tunnel and connected to a lower part of the air intake section; a main body section connected to a rear part of the curved section and extending toward the vehicle rear along the floor tunnel; and an air discharge section, which is connected to a lower part of a rear end portion of the main body section, and which, at a location under a rear end of a front seat, extends outward in the vehicle width direction, the air discharge section having a blowing outlet for blowing air toward the rear seat.
