Abstract: According to one embodiment, a document retrieving apparatus includes a memory and processing circuitry. The memory stores block information indicating a plurality of blocks and a plurality of reference features that is associated with the blocks, the blocks each being a group of semantically relevant sentences included in a document. The processing circuitry extracts a retrieval feature to be used in retrieval from a query that is input, retrieves a first block that is relevant to the query from the blocks based on matching of the retrieval feature with the reference features, and generates display information for conducting an emphasis display of the first block.

Abstract: According to an embodiment, a keyword detection device includes a memory and one or more processors coupled to the memory. The one or more processors are configured to: detect a phrase related to a keyword from text information that is a recognition result of input information represented in a predetermined input form; calculate output similarities conforming to similarities between the phrase and the keywords included in a keyword list in which, for each of a plurality of the keywords, keyword notation of the corresponding keyword is associated with keyword form information representing the corresponding keyword in an input form; and output the keywords in the keyword list according to the output similarities.

Abstract: A particle analyzer (100) includes: a light source that emits excitation light (EL1) including light having a wavelength of 400 nm or less; a lens structure (41) that collects excitation light (EL1) at a predetermined position (51s) in a flow path (53); a detection unit (7) that detects light (FL) emitted from a particle as the particle (51) flowing through the predetermined position is excited by the excitation light (EL1); and a processing unit (120) that processes detection data acquired by the detection unit (7). The lens structure (41) includes a plurality of lenses (411) arranged along an optical axis of the excitation light (EL1); and a lens frame (412) holding the plurality of lenses (411). At least one (G12) of the plurality of lenses (411) is positioned in the lens frame (412) by abutting on a lens adjacent to the lens.

Abstract: A vehicular body front structure, includes: 1) a reactive force member disposed adjacent to a front edge part of a vehicular body and configured to be displaceable from i) a received state where the reactive force member is received in the vehicular body to ii) a protruding state where the reactive force member protrudes to a position higher than a surface of the vehicular body; 2) a mover mechanism disposed between the vehicular body and the reactive force member and configured to displace the reactive force member from the received state to the protruding state; and 3) a shock sensor configured to sense or calculate a collision of the vehicular body with an obstacle to thereby output a sensing signal for moving the mover mechanism.
