  • Patent number: 10898951
    Abstract: Powder particles for forming a homogeneous green body having a sufficient strength and a process for producing a green body by using the powder particles. A green body is shaped by using powder particles of composite particles in which thermoplastic resin particles are scattered on surfaces of large particles in an amount within a predetermined volume ratio range with respect to the large particles, and loaded to form resin pools in contact point peripheral areas of adjoining ones of the large particles and form voids in areas other than the contact point peripheral areas when the thermoplastic resin particles are melted. A green body packed with the powder particles each having a small amount of the thermoplastic resin particles attached thereon is placed under a melting condition of the thermoplastic resin particles, the thermoplastic resin is melted and gathers around contact points (or proximal points) of the adjoining powder particles.

  • Patent number: 10676029
    Abstract: An opening (irradiation opening (90A)), which faces an opening portion of an outer peripheral member and through which an optical axis of an optical member (lamp unit (46)) passes, is formed in a trunk portion (88) that, together with a viewing means (door mirror) for assisting viewing by a vehicle occupant of a vehicle, is covered by the outer peripheral member (visor cover). Further, a wall portion (106), which runs along a peripheral wall of the opening portion and, at a vehicle rear side portion, faces the peripheral wall at a radial direction side, is formed at the trunk portion. Air, which enters into the opening portion while the vehicle is traveling, passes-through a flow path that is bent by the peripheral wall and the wall portion, and the flow rate is reduced, and noise is suppressed.
