Patent number: 11954432Abstract: This disclosure relates to a method of generating a symbol string based on an input sentence represented by a sequence of symbols. In particular, the method involves receiving an input symbol string representing a sentence, generating, using a neural network based on a sequence of dependency structure of elements in the input symbol string, an output symbol string corresponding to the input sentence. The neural network includes an encoder that converts elements of the input symbol string to a first hidden state in a form of a multi-dimensional vector, an attention mechanism that applies a weight to the first hidden state and generates the weighted first hidden state as a second hidden state, a decoder that generates a third hidden state based on at least one element of the input symbol string, an element of the output symbol string, and the second hidden state, and an output generator that generates an element of the output symbol string based on the second hidden state and the third hidden state.Type: GrantFiled: February 14, 2019Date of Patent: April 9, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Hidetaka Kamigaito, Masaaki Nagata, Tsutomu Hirao

Patent number: 10150335Abstract: An assembling method includes fitting an entire range of the guide portion to the stem section with a gap therebetween, and inserting a bolt from an outboard side through a bolt insertion hole formed in the hub wheel. In this state, a maximum inclination angle of the bolt with respect to the hub wheel is set to be larger than a maximum inclination angle of the outer joint member with respect to the hub wheel. The method also includes connecting the bearing and the constant velocity universal joint to each other by threadedly engaging and fastening the bolt into a bolt hole formed in the stem section.Type: GrantFiled: June 16, 2014Date of Patent: December 11, 2018Assignee: NTN CORPORATIONInventors: Tsutomu Nagata, Takayuki Norimatsu

Patent number: 10086649Abstract: A bearing device for a wheel has a wheel bearing including inner and outer rings, a hub wheel, and balls between outer raceway surfaces of the outer ring and inner raceway surfaces of the hub wheel and the inner ring. A stem section is fitted into an inner diameter of the hub wheel to couple a constant velocity universal joint to the wheel bearing through a screw fastening structure so that a shoulder portion of an outer joint member abuts against a crimped portion of the hub wheel. Projecting portions formed on the stem section are press-fitted into the hub wheel having depressed portions formed to interfere with the projecting portions, and a shape of the projecting portions is transferred to the hub wheel providing a projection and depression fitting structure in which the projecting and depressed portions are in close contact at an entire fitting contact portion therebetween.Type: GrantFiled: February 14, 2014Date of Patent: October 2, 2018Assignee: NTN CORPORATIONInventors: Takayuki Norimatsu, Tsutomu Nagata
