Patent number: 10807541Abstract: In the surface structure of an article 7 according to the present invention, a plurality of convex portions 11 are so disposed on a surface 9 as to have intervals relative to each other and a plurality of fine convex portions 21 having a diameter d and a height h smaller than those of the concave portion 11 are formed on the surface of at least the edge portion 15 of the concave portion 11. By this, when a hand touches the surface 9 of the article 7, the proper number of convex portions 21 abut on a linear object 25 constituting a fingerprint 23 of a hand's finger, to thereby allow the human being to obtain a delicate-and-soft touch feeling.Type: GrantFiled: November 17, 2009Date of Patent: October 20, 2020Assignees: NISSAN MOTOR CO., LTD., NATIONAL UNIVERSITY CORPORATION NAGOYA INSTITUTE OF TECHNOLOGYInventors: Akane Ban, Makoto Tamuraya, Takashi Takeuchi, Yeon-Yi Kang, Hideo Fujimoto, Akihito Sano, Hiromi Mochiyama, Naoyuki Takesue, Yoshihiro Tanaka

Publication number: 20170030700Abstract: Irregularities are formed on the surface of an article. At the top of each protrusion of the irregularities, fine irregularities finer than the irregularities are formed. The irregularities are formed so that, in a unit area of the surface of the article touched by a human finger, a ratio of a contact area between the finger and the article is in the range of 35% to 90%. It is preferable to form the irregularities so that the ratio of a contact area between the finger and the article is in the range of 45% to 80%.Type: ApplicationFiled: August 1, 2016Publication date: February 2, 2017Applicant: NISSAN MOTOR CO., LTD.Inventors: Hiroyuki TANAKA, Sumio SAKATA, Akane MOTOFUJI, Kazuya OKAZAKI, Fumi TOYOFUKU, Makoto TAMURAYA

Publication number: 20130129450Abstract: A clip includes a head portion that is engaged with an attachment-subject member, a leg portion that is inserted and locked in an attachment hole of an attachment-base member to which the attachment-subject member is to be fixed, a shank portion that connects the head portion with the leg portion, and a flange portion that spreads obliquely outwards from the shank portion towards the leg portion and is closely attached to the attachment-base member so that an outer circumferential edge portion of a leg-portion-facing surface of the flange portion surrounds the attachment hole when attached to the attachment-base member. The head portion, the leg portion, the shank portion and the flange portion are formed integrally from a resin material through an injection molding using a plurality of molds, an annular parting line PL1 that extends along a boundary surface between the molds is formed on the leg-portion-facing surface of the flange portion.Type: ApplicationFiled: May 17, 2011Publication date: May 23, 2013Inventors: Ryou Aoki, Oomi Arisaka, Yoshiyuki Irie, Makoto Tamuraya, Tomoaki Sasaki

Patent number: 5518270Abstract: A vehicular knee protector device is comprised of a protector body and a pair of brackets. Each bracket is constituted by a V-shaped lower bracket and a V-shaped lower bracket. The upper bracket is fixed to the lower bracket so as to form a polygon space which is preferable deformed when predetermined force is applied to the knee protector device. Further, the lower bracket is formed so that a side to be connected to a vehicle body is structurally stronger than a side to be connected to a protector body to which driver's knees are impacted.Type: GrantFiled: March 29, 1995Date of Patent: May 21, 1996Assignee: Nissan Motor Co., Ltd.Inventors: Koutarou Hanada, Noriki Fujisawa, Tugio Hirose, Hirofumi Sawada, Shuichi Koide, Morimitsu Kobayashi, Makoto Tamuraya, Asao Takei, Yoshiki Kawasaki, Hiroshi Ohyama, Youichi Tanabe

Patent number: 4926295Abstract: To maximize the area of a vanity mirror and improve external appearance of a sun visor under consideration of safety, the sun visor comprises an upper sun visor element, a mirror unit whose upper end is supported by the upper sun visor element, and a lower sun visor element slidably fitted to the mirror unit. In out of use of the mirror, the lower sun visor element is vertically slid to its uppermost position into contact with the upper sun visor element to cover the mirror. In use, the lower sun visor element is vertically slid to its lowermost position with a click feeling to expose the mirror. Further, a lamp unit and a lamp switch are housed within the upper sun visor element for illumination. Further, it is preferable to automatically turn on the lamp whenever the mirror is exposed with the lamp switch set to "AUTO" position.Type: GrantFiled: September 28, 1989Date of Patent: May 15, 1990Assignee: Nissan Motor Co., Ltd.Inventor: Makoto Tamuraya
