Abstract: Disclosed is a transmission device for work vehicles, said transmission device being capable of being used with high-horsepower engines, without an accompanying loss of power transmission efficiency or fuel economy. The transmission device is provided with: an input shaft that transmits power from an engine; a continuously-variable transmission that is disposed on the input shaft and outputs power transmitted from the input shaft, steplessly converting the speed thereof; and a reversing clutch device that outputs, either in a forward rotational direction or a reverse rotational direction, power outputted from the continuously-variable transmission. The reversing clutch device can be selectively switched, and the gear ratio can be steplessly changed by the continuously-variable transmission.

Abstract: At least an embodiment may provide a remote server that can predict overheating of an engine. A remote server may receives an engine rotational speed, an engine load factor, and a cooling-water temperature. The remote server calculates a moving average of the engine load factor during a predetermine time, and calculates a correlation between the moving average of the engine load factor and the cooling-water temperature. If the correlation during a predetermined period is in the status of a predetermined difference from the correlation up to the predetermined period, the remote server predicts occurrence of overheating in a swing working vehicle that is used by a user.

Abstract: An underwater propulsive device of a watercraft including a flotation unit on which a user rides. The propulsion device includes: a hollow body coupled to the flotation unit through a strut and extending in a propulsive direction of the watercraft, the inside of the hollow body being divided into a first compartment and a second compartment; a motor in the first compartment; a propeller in the second compartment; and a power transfer shaft extending in the propulsive direction and connecting the motor and the propeller to each other. The first compartment has a waterproof structure. The second compartment has a water inlet disposed closer to the bow than the propeller is and extending along a circumference of the power transfer shaft and a water jet outlet disposed at a stern-side end of the second compartment. The propeller is smaller than the first compartment in diameter.

Abstract: A remote server is capable of acquiring income distribution of a fishing ground. The remote server receives information on positions of a fishing boat, information on operating days of the fishing boat, and income and fuel consumption of the fishing boat on each operating day or at each position of the operating day. The remote server outputs the income and the fuel consumption for each operating day and makes an income distribution map expressing distribution of corbiculae. The remote server outputs the number of times of receipt of the information on the positions on each operating day on the map and makes a collection spot distribution map expressing distribution of the collection spot by the fishing boat.

Abstract: There is provided a remote server that receives a machine type, an operating day, a position, a load factor, an engine rotational speed, a traveling speed, and a fuel consumption amount. The remote server identifies a working position based on the position, selects past operating days of an operation status corresponding to a current load factor of the same machine at the same working position, identifies a minimum fuel consumption amount out of fuel consumption amounts corresponding to the selected past operating days, and compares a current fuel consumption amount with the past minimum fuel consumption amount. If the current fuel consumption amount is larger than the past minimum fuel consumption amount, the remote server transmits an engine rotational speed and a traveling speed during a working period of the minimum fuel consumption amount, to a predetermined communication terminal corresponding to information for machine identification.

Abstract: An underwater propulsion unit including a propeller, a motor, and a housing. The motor is disposed further forward in a propulsion direction than the propeller and drives the propeller into rotation. The housing that accommodates the motor and the propeller includes a first portion and a second portion. In the second portion disposed further rearward in the propulsion direction than the first portion, an introduction inlet and a spout outlet are provided. The introduction inlet introduces water into the housing, and water introduced from the introduction inlet and delivered by the propeller is spouted out of the housing. When viewed in a direction parallel to the propulsion direction, the introduction inlet is disposed further outward than the first portion and introduces water into the housing in a direction parallel to the axis of the propeller.
