摘要： In the case of a spark plug for an internal combustion engine, having a centre electrode and an earth electrode, which are arranged opposite one another in order to form a discharge path, at least the centre electrode of the two electrodes is provided with a platelet which is attached to the tip of the electrode. The platelet is produced from a metal from the group of noble metals and alloys of the noble metals. The tip of the centre electrode, to which the platelet is attached, may have a smaller diameter than the main section of the centre electrode. The use of a platelet consisting of noble metal extends the life of the electrode, so that a good ignition capability is ensured over a long operating period.

摘要： PURPOSE:To stably turn and run a vehicle regardless of friction coefficient of a road surface, etc., by furnishing a reduction means to reduce driving force of the vehicle at the time when it is judged by a stability judging means that the vehicle is unstable. CONSTITUTION:Stability of a vehicle at the time of turning and running is judged by a stability judging means by detecting a steering angle of a steering wheel by a steering angle detection means and comparing the turning condition caused by this detected steering angle and an actual turning condition detected by a turning condition detection means with each other. When it is judged that the vehicle is unstable, driving force of the vehicle is reduced. Consequently, it is possible to carry out stable control of the vehicle at the time of turning and running by way of taking in the condition of a road surface.

摘要： PURPOSE:To form fingerprint data having sufficiently high contrast necessary for fingerprint collation by adjusting a binarizing threshold for binarizing a difference image so as to increase/decrease it and determining a lower limit value to the binarizing threshold. CONSTITUTION:A difference between fingerprint data and background image data respectively obtained by a fingerprint data sampling means 3 and a background image data sampling means 2 is found out and binarized based upon a threshold through a difference image binarizing means 4 and outputted as a binary gradation data. A dark/light ratio calculating means 5 calculates the dark/light ratio of the binary data obtained by the means 4 and a threshold changing means 6 increases/decreases the threshold of the means 4 so that the dark/light ratio calculated by the means 5 is included within a prescribed range. When the changed threshold is more than the previously determined lower limit and the dark/light ratio is included within the prescribed range, a collating means 7 collates the binary data with previously registered fingerprint data.

摘要： PURPOSE:To maintain and improve the stability of a vehicle by installing a vehicle running state detecting means, a stability judging means and an adjusting means all. CONSTITUTION:A stability judging means M3 first operates an angle of side slip or an angle made by a longitudinal central axis of a vehicle M1 and a forward direction of the vehicle on the basis of running state data detected by a vehicle running state detecting means M2. In addition, this stability judging means M3 judges stability in the vehicle from the size on the basis of the side slip angle operated and estimated. Receiving this judgement, an adjusting means M5 adjusts driving force and/or braking force to a wheel M4. With this adjustment, control conformed to a stable state of the vehicle M1 is made possible, while the stability of the vehicle M1 can be maintained and improved.

摘要： PURPOSE:To enable a high-speed data transmission and a low-speed data transmission without providing any unnecessary transmission circuit by providing a first transmission means that directly transmits stored data and a second transmission means that transmits the data to one of the plural control systems via the other. CONSTITUTION:When output stored data from an external storage device 3 is high-speed transmission data, the data is directly transmitted to a first control system 1 by the first transmission means 4. When the data from the storage device 3 is low-speed transmission data, the data is transmitted to a second control system 2 by the second transmission means 5 via the other second control system 2. As a result, respective stored data can be exactly transmitted at good timings from the external storage device 3 to the respective ones of the first and second control systems 1, 2 at the respective transmission rates respectively necessary for said control systems 1, 2 without providing any unnecessary complicated transmission circuit.

摘要： PURPOSE:To maintain good steering characteristics precisely corresponding to a running condition by providing a means for making judgement as to whether the condition is outside a predetermined range, and changing a driving force distribution ratio of front wheel to rear wheel when the condition is outside said range. CONSTITUTION:An indication means M3 outputs a driving force distribution ratio of front wheel to rear wheel to a driving force distribution means M2, corresponding to steering characteristics set by a setting means M1. On the other hand, an operation means M5 calculates a range of running conditions on the basis of detection by a steering characteristics and steering condition detecting means M4, and a judgement means M7 makes judgement as to whether a running condition detected by a detecting means M6 is within a predetermined range. An instruction for maintaining said distribution ratio when the running condition is within the range, and an instruction for increasing or decreasing the ratio when the condition is outside the range, are respectively outputted to a driving force distribution means M2. According to the aforesaid constitution, the driving force distribution can be controlled to maintain the steering characteristics, even when the running condition has given a change.

摘要： PURPOSE:To obtain the stable brake feeling by individually controlling the variation of the brake power for the front and rear wheels when a vehicle is brake-applied and suppressing the speed variation of the rear wheels. CONSTITUTION:An electronic control unit 12 performs a variety of calculations by receiving each signal of the hydraulic sensors 7, 7a and 7c and wheel sensors 8 and 8a which correspond to each wheel through signal lines 9 and 10, and a control signal is supplied to an actuator 3 from a signal line 11 so that the wheel lock is prevented. Each of the right and left front wheel actuators 3a and 3b and a rear wheel actuator 3c has a solenoid valve 31 for switching the hydraulic pressure to the pressure increasing, maintaining, and reducing mode, and a reservoir and pump part 32 which temporarily stores brake liquid when the brake hydraulic pressure is reduced and which returns the brake liquid to a master cylinder side, and the hydraulic pressure outputted from the actuators 3a-3c is transmitted to the wheel cylinder of each wheel brake 5, and each wheel is brake-applied.
