Patent number: 9540453Abstract: Provided are modified cellulose nanofibers that can be easily formed into a composite with a resin containing a solvent and a resin composition that contains the modified cellulose nanofibers. A method for producing modified cellulose nanofibers is characterized in that a step of obtaining modified cellulose by causing cellulose having hydroxyl groups to react with a resin having an intramolecular polybasic anhydride structure and a step of miniaturizing the modified cellulose are performed in the same step. In this method, the polybasic anhydride structure is a cyclic polybasic anhydride structure obtained by ring formation through dehydration condensation of carboxyl groups in the molecule.Type: GrantFiled: May 13, 2014Date of Patent: January 10, 2017Assignee: DIC CorporationInventors: Tomoaki Harada, Kenichi Hamada, Kazuo Itoya

Publication number: 20160264108Abstract: A collision avoidance apparatus for a vehicle includes an object sensor that detects one or more objects around the vehicle; and an electronic control unit that (i) determines a likelihood for the vehicle to collide with the object, based on at least one of a distance between the vehicle and the object, and a relative speed of the object with respect to the vehicle; and (ii) starts executing a drive support to avoid the collision between the vehicle and the object when the likelihood of the collision is greater than or equal to a first level. A value of the first level is reduced in a case where a number of objects detected by the object sensor is less than or equal to a predetermined number than in a case where the number of the objects is greater than the predetermined number.Type: ApplicationFiled: February 18, 2016Publication date: September 15, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Tomoaki HARADA
