摘要： According to the invention, a primary winding of an ignition coil is coupled with an insulated-gate bipolar transistor (IGBT). The IGBT is controlled by a current restriction circuit, which includes a control transistor for performing the on-off operation of the IGBT such that the IGBT is made conductive upon occurrence of an ignition control signal, and nonconductive, when a primary current of the ignition coil reaches a certain value depending on a reference voltage determined by a bias circuit. The bias circuit has a condenser, which is charged by a base current of the control transistor to change the base potential of the transistor slowly, when the transistor is made nonconductive.

摘要： A main IGBT conducts or blocks a primary current flowing through the ignition coil in response to an input ignition control signal to generate a high voltage on the secondary side of the ignition coil. The main IGBT and a current limiter circuit are integrated in a monolithic silicon substrate of an insulating gate bipolar power transistor. The main IGBT has a collector and agate connected through a depletion IGBT forming part of a constant current circuit, and a resistor. When a voltage generated across the resistor becomes equal to or higher than a zener voltage, a zener diode leads this current to an emitter of the main IGBT.

摘要： A current on the primary side of an ignition coil is subjected to repeated conduction/cutoff control in accordance with an ignition control signal of an ECU to thereby generate a high voltage for ignition twice or more in one combustion stroke. In such a multiple ignition system for an internal combustion engine, the primary current of the ignition coil is detected by a resistor to thereby make the ECU recognize the fact that the primary current has reached a value not smaller than a set value through a signal line when the primary current becomes not smaller than the set value. The ECU determines cutoff timing in the second-time et seq. in the repeated conduction/cutoff control on the basis of the recognition.

摘要： A conductive film includes a layer 1 formed by a conductive material 1 that includes a polymer material 1 containing any of (1) an amine and an epoxy resin (where the epoxy resin and the amine are mixed in a ratio of 1.0 or more in terms of the ratio of the number of active hydrogen atoms in the amine with respect to the number of functional groups in the epoxy resin), (2) a phenoxy resin and an epoxy resin, (3) a saturated hydrocarbon polymer having a hydroxyl group, and (4) a curable resin and an elastomer and conductive particles 1. The conductive film has excellent stability in an equilibrium potential environment in a negative electrode and low electric resistance per unit area in the thickness direction. A multilayer conductive film including the conductive film achieves excellent interlayer adhesion, and using them as a current collector enables the production of a battery satisfying both weight reduction and durability.

摘要： A bearing assembly includes an IC tag with information to be reliably exchanged between the IC tag and an external reader/writer, and a rolling bearing including outer and inner races and rolling elements disposed between the outer and inner races. The IC tag communicates with the external reader/writer device without contacting the reader/writer device, is attached to a metal member of the rolling bearing, includes a tag antenna, and is configured so information can be exchanged between the tag antenna and a reader/writer antenna of the reader/writer device by forming a closed magnetic circuit between the tag antenna and the reader/writer antenna. The IC tag is received in a hole in a metal member surface. The tag antenna includes at least two protrusions facing the opening of the hole and arranged so magnetic fluxes leaving/entering the protrusions pass inside the edge defining the hole opening and extend outside the hole.
