  • Publication number: 20220130270
    Abstract: To reduce the burden on the grader while minimizing variations in grading, a grading support device 30 comprises: an acquisition unit 31; an extraction unit 32; and a grading unit 33. The acquisition unit 31 acquires an answer file that includes information associated with the answer to a question. The extraction unit 32 extracts the answer from the answer file acquired. The grading unit 33 grades the extracted answer using learning results obtained through machine learning of the relationship between the answer and the grading results.

  • Patent number: 10082266
    Abstract: A vehicle lamp 10 includes a lamp body 11, a sealing material 42, and a lens member 12 and a leg portion 41. A groove portion 31 is formed in the lamp body 11. The sealing material 42 is filled in the groove portion 31. The leg portion 41 is provided on the lens member 12. The leg portion 41 is inserted into the groove portion 31 to thereby fix the lamp body 11 and the lens member 12 together via the seal material 42. A narrow portion 51 is provided at a bottom side of the groove portion 31 and a wide portion 52 is provided at an opening 35 side of the groove portion 31. A gap of the wide portion 52 is wider than the gap of the narrow portion 51. The amount of sealing material 42 used in vehicle lamp 10 is limited while ensuring an easy assemblage.
