Patent number: 11960836Abstract: An index value assignment device comprises: a selection unit that prompts a user to select, from a sentence, one or more words that the user feels to have a same degree of a predetermined index value with respect to one or more first words for which the index value is known; a validation unit that validates the selection result by the user on a basis of the index value of a second word for which the index value is known from among the one or more words included in the selection result; and a determination unit that determines the index value with respect to a third word for which the index value is unknown from among the one or more words selected by the user, on a basis of the index value of the first word according to the selection result for which the selection result is determined to be valid. Consequently, the efficiency of assigning word familiarity is increased.Type: GrantFiled: March 11, 2020Date of Patent: April 16, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yoshinari Shirai, Tessei Kobayashi, Sanae Fujita, Masafumi Matsuda, Yasue Kishino

Patent number: 9890854Abstract: A vehicular shift operation apparatus that includes a manual transmission including an input-side sub-transmission and an output-side sub-transmission, and that is capable of preventing overrun or underrun due to erroneous shift operation, is provided. The vehicular shift operation apparatus includes a manual transmission including an input-side sub-transmission and an output-side sub-transmission, and includes: a main shaft rotation speed sensor that detects a main shaft rotation speed, a sensor that detects a position of a clutch pedal, and a controller. The controller has a function of detecting a gear stage at a control cycle (current gear stage) and a function of determining whether the detected gear stage is correct or not.Type: GrantFiled: June 18, 2015Date of Patent: February 13, 2018Assignee: VOLVO TRUCK CORPORATIONInventor: Masafumi Shirai
