Patent number: 9004576Abstract: When a collision load is transmitted to a gusset, the load is transmitted to an inner side in a vehicle width direction via an inclined wall. Accordingly, moment that causes a front side member to be projected and bent inward to the inner side in the vehicle width direction with an intersection being a starting point acts on the front side member. Then, the front side member, which has been projected and bent inward, collides with a power unit that is disposed in an engine compartment from an outer side in the vehicle width direction. Accordingly, a lateral force to the inner side in the vehicle width direction can be obtained for a vehicle.Type: GrantFiled: September 11, 2014Date of Patent: April 14, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kosuke Sakakibara, Tomoyuki Kuriyama, Akihiro Tamaoki, Kenjiro Yamada, Shintaro Kitakata, Yasuyuki Hihara, Yasutaka Hasegawa

Patent number: 5902104Abstract: An orthodontic wire supporting device, for example, in the form of a bracket improved so that the bracket can be reliably held on teeth during a period of orthodontic treatment but easily detached from teeth, if it is desired, for exchange of the bracket with a fresh one. A base of the bracket destined to be bonded to the tooth plane by means of an adhesive layer is formed adjacent four corners with anchoring holes each defined by a truncated cone having its diameter on the upper side smaller than its diameter on the lower side of the base. The lower side of the base is coated with the adhesive layer, and then the base is pressed against the tooth plane with an appropriate force so that the adhesive layer is partially forced to pass through the respective anchoring holes and to project from the upper side of the base.Type: GrantFiled: December 1, 1997Date of Patent: May 11, 1999Inventor: Kenjiro Yamada
