Abstract: A system for automatically determining a mooring direction or a berth approach direction of a boat. The system including a control unit including a processor. The control unit is configured to obtain image information, the image information including information of an other boat that is moored; identify a mooring direction of the other boat based on the image information; determine the mooring direction or the berth approach direction of the boat based on the mooring direction of the other boat, wherein the control unit determines an automatic mooring route of the boat based on the mooring direction or the berth approach direction of the boat, and the control unit outputs a control signal for controlling an automatic mooring of the boat.

Abstract: Constant-speed-travel-apparatus controlling prime-mover so that mobile-body mounted with the prime-mover travels at constant-speed, includes: function-operation-member being instructed activation of speed-maintaining-function of the mobile-body in response to operation by operator; first-speed-operation-member being instructed the travel-speed of the mobile-body in accordance with operation-amount by the operator; second-speed-operation-member being instructed change of the travel-speed by predetermined amount in response to operation by the operator in state where activation of the speed-maintaining-function has been instructed through the function-operation-member; and electronic-control-unit controlling output of the prime-mover based on the operation-amount of the first-speed-operation-member and number of times of operation of the second-speed-operation-member so that the mobile-body travels at constant-speed in the state.

Abstract: An engine speed control device for a vessel in which a plurality of outboard motors are mounted on a hull, has a control unit that performs control, on the basis of an operation of one switch, so as to set engines of the outboard motors to a synchronous mode in which the engines have an identical engine speed, wherein the control unit determines in advance an engine to serve as a reference among the engines of the outboard motors, and automatically changes the mode to the synchronous mode in which the engine speeds of engines other than the reference engine become equal to the engine speed of the reference engine when all the engines satisfy a condition to transit to the synchronous mode.

Abstract: A method for producing an aroma composition from an animal or plant material, including fragmenting an animal or plant material to give a crude fragmented pieces of the material that contains minor fragments, removing minor fragments from a gas that contains aroma compounds emitted from the material in fragmenting the material and minor fragments, applying the gas from which minor fragments have been removed to an adsorbent to thereby make the aroma compounds adsorbed by the adsorbent, and collecting the aroma compounds from the adsorbent to prepare an aroma composition containing the aroma compounds. The adsorbent is held in an adsorbent holder in an aroma compound adsorbing device, and the adsorbent holder has a mesh lid at both ends thereof in the gas flowing direction therethrough.

Abstract: A coffee flavor improver of a solution that contains aroma compounds emitted in grinding roasted coffee beans, the solution being a propylene glycol solution or a combination thereof, that gives an aroma perceivable in grinding roasted coffee beans and includes in a total ion chromatogram obtained through EI mode at 70 eV using a GC/MS and using polar columns, the chromatogram has peaks for 2-methylfuran, 2-methylbutyl aldehyde, isovaleraldehyde, 2,5-dimethylfuran, 3-hexanone, 2-vinylfuran, pyridine, 2,5-dimethylpyrazine, 2-ethyl-6-methylpyrazine and 3-ethylpyridine, the ratio of the total area of all the peaks having a retention index not more than that for acetoin to the total area of all the peaks in the chromatogram, and the ratio of the total area of all the peaks having a retention index larger than that for acetoin to the total area of all the peaks in the chromatogram are fall within a specified range.

Abstract: A method for producing an aroma composition from roasted coffee beans, including grinding roasted coffee beans to give a crude ground powder of roasted coffee beans that contains a fine powder and thin flakes, removing the fine powder and thin flakes from a gas that contains aroma compounds emitted from the roasted coffee beans in grinding the roasted coffee beans and the fine powder and thin flakes, introducing the gas from which the fine powder and thin flakes have been removed into an adsorbent to thereby make the aroma compounds adsorbed by the adsorbent, and collecting the aroma compounds from the adsorbent to prepare an aroma composition containing the aroma compounds. The adsorbent is held in an adsorbent holder in an aroma compound adsorbing device, and the adsorbent holder has a mesh lid at both ends thereof in the gas flowing direction therethrough.

Abstract: A marine wireless communication system is capable of reliably and stably monitoring an outboard engine unit in a watercraft. The marine wireless communication system comprises at least one first wireless device disposed in at least one outboard engine unit secured to a stern of a watercraft, and at least one second wireless device disposed inside the watercraft, the first wireless device communicating with the second wireless device according to a predetermined protocol.
