  • Patent number: 10247163
    Abstract: An ignition device for an internal combustion engine is provided which improves ignition while reducing electric power consumption. An ignition device for an internal combustion engine includes an ignition plug that is placed with a tip exposed on an end in an axial direction of a combustion chamber formed in a cylinder and that includes a central electrode and a grounding electrode provided opposing each other at the tip, and a magnetic field former that forms a magnetic field in a direction in which a magnetic field vector substantially vertically passes through an approximate two-dimensional plane including a spark discharge path formed, by a gas flow ejected to the end in the axial direction of the combustion chamber, between the central electrode and the grounding electrode, and extending in an approximate U shape in a direction orthogonal to the opposing direction of the electrodes.

  • Patent number: 9843675
    Abstract: A receiving unit receives positional information of a terminal device. A storage unit stores a list in which a plurality of correspondence relationships between an area and an identifier are included. An adjusting unit adjusts the correspondence relationship included in the list. A first selection unit selects, from the adjusted list, an identifier corresponding to the received positional information. A first transmission unit transmits the selected identifier to the terminal device. An input unit inputs information on an area to be called. A second selection unit selects, from the adjusted list, an identifier corresponding to the input information. A second transmission unit transmits a call signal including the selected identifier.

  • Patent number: 9683480
    Abstract: In a spark ignition engine, a thermal insulation thin layer is formed over a wall surface, facing an inside of a combustion chamber, of a base material forming the combustion chamber, and for a thermal conductivity ? [W/(m·K)], a thermal diffusivity ? [mm2/s], and a thickness L [?m] of the thermal insulation thin layer, L?16.7×? and L?207.4×(?)0.5 are satisfied. With such a configuration, a heat loss Q_total escaping from gas in a cylinder to the wall of the combustion chamber over all strokes can be reduced, and the thermal efficiency can be improved without inducing degradation of knocking due to an increase in an amount of heating Q_intake of the gas in the cylinder during an intake stroke.

  • Publication number: 20160160754
    Abstract: A controller for a free piston generator that is capable of more accurately controlling the behavior of a piston than conventional controllers is provided. During power generation of a free piston generator 10, a controller 18 controls the amount of power generation to cause the velocity of a piston 14 to reach a first velocity command value (for an expansion stroke) and a second velocity command value (for a compression stroke) by electric braking. During motoring, the controller 18 controls the amount of power supply to cause the velocity of the piston 14 to reach the first and second velocity command values. The controller 18 sets the first and second velocity command values by setting first and second velocity command values for a certain round-trip period based on a top dead center position and a bottom dead center position of the piston 14 for the previous round-trip period.

  • Patent number: 9295173
    Abstract: A casing for electrical equipment has a drip-proof structure and includes a first plate and a second plate. The first plate has a plurality of first openings and a plurality of tongue-shaped louvers disposed in the respective first openings. Each louver has a lower end continuous to the first plate. The upper end side of each louver is folded to a back side of the first plate, The second plate is disposed on a front of the first plate. The second plate has a plurality of second openings each having a smaller area than each first opening. The first and second plates are overlapped with each other so that the first and second openings communicate with each other, forming a louver structure. The first and second plates are coated in the overlapped state with a result that a gap between them is filled with a paint.
