Abstract: In a ship control system of one embodiment, a route command unit outputs a route command including a target ship position and a target bow direction of a ship. An information detector detects ship information including an actual ship position and an actual bow direction of a ship. An external force vector estimation unit estimates an external force vector received by a ship, using the ship information and a hull motion model related to a hull motion of the ship. A control command unit controls both rotational frequency of a main engine and a rudder angle of a ship, based on the route command, the ship information, and the external force vector.

Abstract: A ship monitoring system includes: a shipboard information processing apparatus and including a shipboard communication unit and an information acquisition unit; and a support information processing apparatus and including: a support side communication unit capable of communicating with the shipboard communication unit; a time lag identification unit; and a state prediction unit. The time lag identification unit identifies a time from transmission of the ship motion information from the shipboard communication unit to reception of the ship motion information by the support side communication unit as a reception time lag. The state prediction unit inputs the ship motion information and the reception time lag to a ship motion model related to the ship motion of the ship to predict a motion state of the ship ahead of a motion state of the ship indicated by the ship motion information by a period of time based on the reception time lag.

Abstract: In a ship control system of one embodiment, a main engine controller performs, when controlling the rotational frequency of a main engine based on a target ship speed of a ship, feedback control of an actual ship speed of the ship to perform ship speed control for bringing the actual ship speed closer to the target ship speed. A turning judgment unit judges whether or not the ship will turn. A control change unit performs, when the turning judgment unit has judged that the ship will turn, lowering processing for lowering the responsiveness of the ship speed control.

Abstract: A pneumatic tire can include a pair of sidewall portions, where an outer surface of the sidewall portion can include a marking portion. The marking portion can include a first region forming a mark, a second region that is a background portion of the mark, and a fringing portion that demarcates the first region from the second region and fringes the contour of the mark. The first region can be formed as a smooth surface. The second region can be a projection-recess region where a plurality of micro projections are arranged. The fringing portion can be a rib projecting from the first region.

Abstract: A lens barrel 100 includes a fifth lens group unit 25, a focus ring 31, an internal gear 31b, a pinion gear 41, a detection magnet 43, and a GMR sensor 44. The internal gear 31b rotates integrally with the focus ring 31 and has a plurality of gear portions 31c. The pinion gear 41 is provided on the inner peripheral surface side of the focus ring 31 and has a gear portion 41a that mates with the gear portion 31c of the internal gear 31b, and a guide shaft 42 that is inserted through the center of the gear portion 41a. The guide shaft 42 is inserted through the detection magnet 43, and the detection magnet 43 rotates integrally with the gear portion 41a and has a magnetized surface 43b on which different magnetic poles are alternately magnetized. The GMR sensor 44 is fixed to a member separate from the detection magnet 43, is provided at a position adjacent to the detection magnet 43, and detects the rotation of the detection magnet 43 that rotates along with the pinion gear 41.

Abstract: To provide a research result distribution platform that is highly convenient for researchers and people trying to use research results. A research result acquisition unit acquires research result information indicating results of research of researchers. A management unit manages one or more pieces of research result information acquired by the research result acquisition unit, for each researcher. An extraction unit extracts the research result information desired by a user from the one or more pieces of research result information managed by the management unit. A research result presentation unit presents the research result information extracted by the extraction unit to the user. The problem is solved thereby. For both researchers and users, gaining and losing of service points to make the research result distribution platform more active is controlled.

Abstract: A heat sink including a heat sink body having a heat-absorbing surface that absorbs heat transferred from a heat-generating body, and a heat-dissipating surface that externally radiates the heat; a holding member that is held against the heat-absorbing surface; and a fixation portion that is provided on the heat sink body, that fixes the holding member so as to be incapable of coming loose from the heat sink body, and that suppresses displacement in a planar direction in which the heat-absorbing surface extends.

Abstract: To provide a research result distribution platform that is highly convenient for researchers and people trying to use research results. A research result acquisition unit 111 acquires research result information indicating results of research of researchers R. A management unit 102 manages one or more pieces of research result information acquired by the research result acquisition unit 111, for each researcher R. An extraction unit 103 extracts the research result information desired by a user U from the one or more pieces of research result information managed by the management unit 102. A research result presentation unit 141 presents the research result information extracted by the extraction unit 103 to the user U. The problem is solved thereby.
