Patent number: 9690217Abstract: A triarylamine derivative is represented by general formula (I). In general formula (I), R1 and R2 each represent, independently of one another, a chemical group selected from the group consisting of a halogen atom, an optionally substituted alkyl group having a carbon number of 1-6, an optionally substituted alkoxy group having a carbon number of 1-6, and an optionally substituted aryl group having a carbon number of 6-12. In general formula (I), k and l each represent an integer of at least 0 and no greater than 4. When k and l represent integers greater than 1, chemical groups R1 bonded to the same aromatic ring and chemical groups R2 bonded to the same aromatic ring may be the same or different to one another. In general formula (I), m and n each represent a different integer of at least 1 and no greater than 3.Type: GrantFiled: August 27, 2015Date of Patent: June 27, 2017Assignee: KYOCERA Document Solutions, Inc.Inventors: Hideki Okada, Fumio Sugai, Kensuke Kojima, Hiroki Tsurumi, Yohei Yamamoto, Eiichi Miyamoto

Patent number: 9688311Abstract: At a vehicle, rockers and torque boxes are connected, from a front side, to first connecting portions of spacers. Joined portions of the rockers and the torque boxes are reinforced, and a front wheel directly hitting the joined portion at a time of a collision is suppressed. Separation of a joined portion of a front pillar and a dash panel, whose origin is separation of the previously-mentioned joined portion, can be suppressed. Front portions of the spacers are disposed further toward a front side than the joined portions of the front pillars and the dash panel. Therefore, the front wheel first hits the spacer, and collision load is transmitted to the rocker and the torque box, and thus, input of an excessive collision load to the dash panel is suppressed. Because the first connecting portions extend in a vehicle transverse direction, the spacers becoming large can be suppressed.Type: GrantFiled: August 12, 2014Date of Patent: June 27, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yohei Yamamoto, Koi Hata, Yujiro Kaji

Patent number: 9684253Abstract: A triphenylamine derivative is represented by general formula (1). In general formula (1), R1 to R7 each represent, independently of one another, a chemical group selected from the group consisting of a halogen atom, an optionally substituted alkyl group having a carbon number of at least 1 and no greater than 6, an optionally substituted alkoxy group having a carbon number of at least 1 and no greater than 6, and an optionally substituted aryl group having a carbon number of at least 6 and no greater than 12. Also, k, l, m, n, o, and p each represent, independently of one another, an integer of at least 0 and no greater than 4. When any of k, l, m, n, o, or p represents an integer greater than 1, chemical groups R3, R4, R5, R6, or R7 bonded to the same aromatic ring may be the same or different.Type: GrantFiled: August 27, 2015Date of Patent: June 20, 2017Assignee: KYOCERA Document Solutions Inc.Inventors: Hideki Okada, Kensuke Kojima, Fumio Sugai, Hiroki Tsurumi, Yohei Yamamoto, Eiichi Miyamoto

Patent number: 9555836Abstract: In a vehicle, a gusset is provided at a lower end portion of a front pillar, a body wall portion of the gusset is joined to the front pillar, and a bottom wall portion of the gusset is joined to an upper wall portion of a rocker outer reinforcement. Thus, when the front pillar is about to collapse rearward, the upper wall portion supports the bottom wall portion of the gusset from below the vehicle. Therefore, the front pillar is restrained from collapsing. Besides, the rocker outer reinforcement receives, on a surface thereof, a load input from the gusset. Therefore, the load input to the rocker outer reinforcement is dispersed, so the load can be restrained from concentrating.Type: GrantFiled: September 15, 2014Date of Patent: January 31, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yohei Yamamoto, Koui Hata, Yujiro Kaji
