摘要:
A short-term planned route from a start position that is a ship position at a first time up to an end position that is the ship position at a second time is designed based on a planned route, an estimated encounter marine phenomenon information, operation performance information measured on a ship, and a hull motion model of the ship, the estimated encounter marine phenomenon information being measured on the ship based on actually encountered marine phenomenon information. The short-term planned route makes a first evaluation function optimal, the first evaluation function containing: an index indicating an influence of a fluctuation portion between a planned position that is a ship position planned at the second time on the planned route and the end position; a fuel consumption index when the ship sails along the short-term planned route; and a safety index when the ship sails along the short-term planned route.

In a method for preparing a hydrogen absorbing electrode, a hydrogen absorbing alloy which contains a rare earth element as an alloy constituent and a transition metal element is immersed in an aqueous alkaline solution so that the saturation mass susceptibility is 1.0 to 6.5 emu/g of the hydrogen absorbing alloy. The hydrogen absorbing alloy is mixed through the immersing step with an oxide or hydroxide of a rare earth element wherein the oxide or hydroxide has as a main component at least one element selected from the group consisting of Dy, Ho, Er, Tm, Yb, and Lu. Then, a mixture of the hydrogen absorbing alloy and the oxide or hydroxide of the rare earth element is applied to form a desired shape.

摘要:
In a power supply device including a fuel cell unit with a stack of fuel cells or a fuel cell stack and a secondary battery, an intermittent drive mode is selected under a preset condition to receive power supply only from the secondary battery. The control procedure of the invention determines whether a temporary stop of the fuel cell stack or continuance of the stop of the fuel cell stack leads to potential performance deterioration of the fuel cell stack at a restart of the fuel cell unit. In response to estimation of the potential performance deterioration, the control procedure controls the power supply device to continue or start power generation of the fuel cell stack, regardless of selection of the intermittent drive mode under the preset condition.

摘要:
A strain detector includes a bridge circuit having at least two strain resistance elements, a substrate, a first fixed member, and a second fixed member. The substrate has a circuit portion electrically connected to the strain resistance elements. The strain resistance elements are arranged on the substrate. The first fixed member is fixed to a center of an area, where an outer periphery of the area is set at a position at which the strain resistance elements are arranged. The second fixed member is fixed outside the position, where the strain resistance elements are arranged at the substrate. A center of an axis of the first fixed member, a center of an axis of the second fixed member, and the center of the area are positioned on a straight line, and the first fixed member and the second fixed member are arranged on two mutually opposed surfaces of the substrate.
摘要:
The fuel cell system is provided which detects a freeze among specific components and portions thereof by evaluating various conditions upon starting operation of the fuel cell system. If a freeze is detected through those evaluations, the start of the system is prohibited in order to prevent some deterioration in the fuel cell system.
