摘要： A multi-gap spark ignition device to be installed in a spark ignition engine, is disclosed. The device comprises a metallic base member provided with a hole which forms one portion of the combustion chamber of the engine. Within the wall defining the hole, a high voltage electrode, a plurality of intermediate electrodes and an earth electrode are embedded at regular intervals so that each end of the electrodes project into the hole to form a plurality of spark gaps between the adjacent ends of the electrodes. Each of the intermediate electrodes is composed of an electrode member and an insulating member for covering one end of the electrode member, and is closely inserted into a groove formed in one end surface of the base member along the hole thereof at regular intervals. By making the stray electrostatic capacity between the base member and the opposed electrode member of each intermediate electrode larger than the electrostatic capacity between the adjacent electrode members, the required voltage can be maintained small irrespective of the number of the intermediate electrodes.

摘要： An ignition system for internal combustion engines of the type in which after the energizing current flow to the primary winding of an ignition coil has been interrupted and an ignition spark generating high voltage has been produced in the secondary winding, the primary winding is energized again to interrupt the ignition spark. The ignition spark is interrupted at around the TDC only when the engine is at high speed operating conditions and the deenergizing current in the primary winding is not interrupted in a moment but decreased gradually. Also, the ignition spark is interrupted only when the ignition spark is to continue beyond the top dead center.

摘要： An ignition system for the internal combustion engine comprising a high voltage circuit for generating a spark, having the primary and secondary windings. In response to a first signal, the current in the primary winding is cut off thereby to generate a high voltage at the secondary winding. In response to a subsequent second signal, the primary winding is shorted thereby to cut off the high voltage thus far generated in the secondary winding, thus properly regulating the duration of the spark generated.

摘要： The temperature of a glow plug mounted on an epitorocoidal engine housing on a leading side of the torocoid minor axis of a rotary piston engine in the direction of the rotor rotation is sensed. When the sensed temperature exceeds a predetermined temperature within a temperature range which allows the ignition of air-fuel mixture, power to the glow plug is stopped whereby the life of the glow plug is extended and the power consumption is saved.

摘要： A logarithmic function generating system which generates an output signal bearing a logarithmic functional relation to the input signal. The time constant RC of a resistance-capacitance circuit is increased for every unit time elapsed in proportion to the unit time to produce a broken line approximating the logarithmic function. With its simple circuit construction employing no elements whose characteristics vary with ambient temperature changes or which tend to involve variations in characteristics among the elements of the same type, the system is capable of generating the desired logarithmic function output with a high degree of accuracy.
