The basic elements of a magnetic bubble device are laminated. A spacer conductor pattern layer is formed on the same plane as a control conductor pattern layer interposed between a magnetic film which forms and holds magnetic bubbles and a propagation circuit pattern layer adapted to control the magnetic bubbles so as to make substantially uniform the distance between the propagation path and the magnetic film.

An electronic control unit detects a manner of fluctuation of a fuel pressure with injection of fuel by a fuel injection valve with the use of a fuel pressure sensor, and calculates a tendency of deviation of an actual fuel injection characteristic of the fuel injection valve with respect to a basic fuel injection characteristic on the basis of a result of comparison between a detected temporal waveform and a basic temporal waveform. The tendency of deviation is reflected at a predetermined reflection rate (R) at the time of updating a learned value (Gij) for compensating for an individual difference of the fuel injection valve. The predetermined reflection rate (R) is increased when an accumulated value (D) of a vehicle travel distance is shorter than a predetermined value (Dth) as compared with when the accumulated value (D) is longer than or equal to the predetermined value (Dth).

A light-emitting apparatus has a light-emitting device and a supporting board. The light-emitting device has a pair of n-electrodes with a p-electrode therebetween, on the same plane. The supporting board includes an insulating substrate on which positive and negative electrodes are formed, opposing to the p- and n-electrodes of the light-emitting device, respectively. Bonding members bond the p- and n-electrodes with the positive and negative electrodes, respectively. The positive electrode on the supporting board is formed within the width region of the p-electrode and narrower in width than the width of the p-electrode, in a cross-section along a line extending through the pair of n-electrodes. The negative electrodes oppose to the n-electrodes, respectively, with the same widths, or with that side face of each of the negative electrodes which faces the positive electrode being retracted outwardly from that side face of each of the n-electrodes which faces the p-electrode.

An embodiment of a nuclear power plant has: a reactor vessel containing a core; a reactor containment vessel containing the reactor vessel; and a radiation heat reflecting member disposed at a portion below the reactor vessel inside the reactor containment vessel. The radiation heat reflecting member may block radiation heat, which is emitted toward a side wall surface of the reactor containment vessel from the core that has been put in a molten state by an accident and flowed downward from the reactor vessel to be accumulated at a lower portion of the reactor containment vessel. The radiation heat reflecting member may block radiation heat, which is emitted toward a supporting structure supporting devices disposed inside the reactor containment vessel.

A method of estimating an air-intake amount of an internal combustion engine is provided. The method may comprise detecting a fluid energy amount in an interior of an air-intake passage at first and second points in time while an intake valve is closed from a compression stroke to an exhaust stroke, and calculating a predicted air-intake amount using the values of the fluid energy amounts at the first and second points with reference to an air-intake amount calculation map showing a correlation between the values of the fluid energy amounts at the first and second points and the predicted air-intake amount in the intake stroke, the air-intake amount calculation map being pre-created by finding the values of the fluid energy amounts in the air-intake passage at the first and second points and the air-intake amount, for plural running states of the internal combustion engine.
