Abstract: A vehicle cruise control apparatus is provided for controlling a vehicle to run at a set speed desired by a driver. The apparatus stores a state in which the driver inputs a set speed (for example, the number of times the driver inputs the set speeds and a period at which the driver inputs the set speeds), and calculates a target acceleration/deceleration from the input state and a vehicle speed deviation (calculated by subtracting the actual vehicle speed from the set speed).

Abstract: A center core 1, a secondary coil 3 wound at a secondary bobbin 2 and a primary coil 5 wound at a primary bobbin 4 are placed concentrically inside a coil case 6 in sequence from the inside of the coil case. One end of the secondary coil 3 is connected to the primary coil side and becomes a low-voltage side, and the other side becomes a high-voltage side due to an induced voltage and used with connection to the individual ignition plugs of the internal combustion engine. The radial thickness of the bobbin at the low-voltage side 3a and the high-voltage side 3c of the secondary coil, each located at the both ends of the secondary coil, is made larger than the radial thickness of the bobbin at the center part 3b of the secondary coil. The radial thickness of an insulating layer 8 between the secondary coil 3 and the primary coil 5 at the low-voltage side 3a of the secondary coil is smaller and the radial thickness of the insulating layer at the high-voltage side 3b of the secondary coil is larger.

Abstract: An ignition apparatus is received in a plug hole which is formed by a cylinder head and a cylinder head cover of an internal combustion engine. A side core has a slit between two horizontally extending side wall ends. The side core is selected from a laminated sheet structure comprised of two grain oriented silicon steel sheets, each having a slit between two horizontally extending side wall ends, and the plural slits align at substantially the same position. The slit prevents a one-turn short of a magnetic flux of the side core. Thereby a predetermined secondary voltage more than an engine requirement secondary voltage is obtained. An ignitor reception portion has an independent and individual ignitor reception portion and an independent and individual coil reception portion, with the ignitor reception portion and the coil reception portion being combined.
