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: 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 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: A method of producing a phosphate-coated SmFeN-based anisotropic magnetic powder, the method including stirring a slurry containing a raw material SmFeN-based anisotropic magnetic powder, water, a phosphate source, and an aluminum source to obtain a SmFeN-based anisotropic magnetic powder having a surface coated with a phosphate.

Abstract: A printing apparatus includes a carriage mounted with a printing unit; a first motor configured to move the carriage in a predetermined direction; a second motor configured to move the carriage in the predetermined direction; and a control unit. The control unit executes a first mode in which, when causing the printing unit to perform printing under a first printing condition, the first motor is driven in a first direction and the second motor is driven in the first direction, and a second mode in which, when causing the printing unit to perform printing under a second printing condition different from the first printing condition, the first motor is driven in the first direction and the second motor is driven in the first direction while changing an output ratio between the first motor and the second motor.

Abstract: A breathable salt core is provided that is placed in a cavity of a casting mold in order to mold a hollow part of a cast product and that is dissolved and removed after casting, the breathable salt core being formed by powder molding innumerable salt particles into a predetermined shape corresponding to the hollow part, wherein a gap that can retain a gas remaining in the cavity in a casting process is formed between the innumerable salt particles that have been powder molded. The breathable salt core thus manufactured assures that residual gas within the cavity pushed by the molten metal to enter the gap formed between salt particles of the salt core, thereby avoiding any incomplete filling of the molten metal, and which can be formed with a simple production process at a low cost.

Abstract: To make it possible to easily use video data of raw data of a high frame rate input from a single-chip camera in a server system that is different from an AV server system in which an AV server itself is included. First AV clip data is obtained by performing a compression encoding process to raw data of a high frame rate input from a single-chip camera and is written in a storage. The raw data of the high frame rate is obtained by reading the first AV clip data from the storage and processing a compression decoding process on the first AV clip data, video data of a high frame rate is obtained by performing a demosaic process on the raw data, and second AV clip data is obtained by performing a compression encoding process on the video data and is written in the storage. The second AV clip data is read from the storage and transmitted to a second AV server system that is different from a first AV server system in which an AV server itself is included.

Abstract: To increase the number of IO ports and to increase the storage amount easily. An AV server system includes: a plurality of AV servers including internet protocol (IP) input-output ports for connecting to other AV servers, the IP input-output ports being independent from input-output ports to an outside of the system; a client controller configured to control the plurality of AV servers; a manager storing information relevant to AV clip data recorded in the plurality of AV servers and AV clip data input into the plurality of AV servers; and a frame synchronization unit configured to perform frame synchronization between the plurality of AV servers.

Abstract: A light-emitting element with a lower voltage and higher emission efficiency is provided. The light-emitting element includes a first organic compound, a second organic compound, and a guest material. The LUMO level of the first organic compound is lower than the LUMO level of the second organic compound, and a difference between them is larger than 0 eV and smaller than or equal to 0.5 eV. Furthermore, the HOMO level of the first organic compound is lower than the HOMO level of the second organic compound. The guest material has a function of converting triplet excitation energy into light emission. The first organic compound and the second organic compound form an exciplex.
