摘要： PROBLEM TO BE SOLVED: To equip motorcycle with possibility of kick starting in the case where it is furnished with an anti-theft circuit based on transmission and reception of the ID code. SOLUTION: The supply voltage from a generator 1 capable of rotating even at the time of kick strutting is connected with the primary winding 5a of a transformer 5, and circuit voltage is supplied to an ignition control circuit 7 and stabilizing power supply circuit 8 through two secondary windings 5b and 5c, and the boosted voltage is passed through the circuit 8 and made a constant circuit voltage and is supplied to an anti-theft circuit 9. Thereby it is possible to boost the circuit voltage of the anti-theft circuit to a level which enables the operation, even when the generated voltage by the generator at the time of kick starting is low, and therefore, the kick starting in case the normal key is used can be executed without any problem.

摘要： PROBLEM TO BE SOLVED: To prevent that the CPU comes to permit the engine ignition control by malfunction of the CPU, by a noise in order to start the engine fraudulently. SOLUTION: After the resetting of a CPU at its operation starting time (ST1), the rotational condition of an engine is detected (ST2), and when the rotation of the engine is not more than a specific threshold value, the recognition finish condition of a regular code signal is cancelled (ST3), and it is made in the receiving waiting condition of the above code signal, and the code signal is discriminated, and when the regular code signal is received, the process of the code signal recognition finish is carried out newly, so as to carry out the ignition control (ST6). When an abnormal condition of the CPU is detected, the CPU is reset (ST1), to return to the rotational condition detecting step of the engine, so as to carry out the above control flow again. When the CPU is malfunctioned by going to start the engine irregularly, the code recognition finish condition is released and no ignition control is carried out, because the engine is not in the rotation, even though the processing of the code recognition finish is carried out.

摘要： PROBLEM TO BE SOLVED: To early and securely confirm a key and improve the starting property by detecting the header part from a receive signal by a receiver side controller and transferring so as to synchronize therewith and collating the ID code part. SOLUTION: This structure is provided with a controller connected to the ON-position of a key cylinder side to trim the signals from a transmitter and receive only the whole length predetermined and store in a memory and further, confirm whether the signals can synchronize with transmitting signals and these are Manchester-coded. When the signals are not synchronized like a pattern (b) although the header is almost in the foremost position, one bit of the foremost or tail part is transferred to the foremost or tail part to synchronize with the signals like a pattern (a) and collate the ID code part after retrieval of the header part. When the signals are received from the middle of the ID code part like a pattern (c), after the header part is retrieved at first, the front and tail end parts are transferred to synchronize therewith, the ID code part is collated. Since the signal is processed in an extremely high speed, a key can be rapidly and securely confirmed.

摘要： PROBLEM TO BE SOLVED: To enhance power saving, and also prevent AM noise, in an electrical actuator driver. SOLUTION: A large-capacity capacitor 6 is connected to a power line 2a connected from a power unit 2 to a control unit 1, and a motor 6 is driven by controlling a drive element FET 1b by mean of a CPU 1a, according to the operation signal from a switch box 5 at hand. Accordingly, the power unit can be made into low capacity, by using a capacitor as a power source, thus the downsizing of the device can be enhanced, and additionally not only can AM noise be reduced, but also the reduction in power and the adoption of a countermeasure to higher harmonic currents become easy, because there is no need for letting a current flow more than it, when the charge is completed at waiting, and also the safety rises by power output being limited automatically.

摘要： PROBLEM TO BE SOLVED: To prevent the stop of an engine ignition control due to the instant turning off of CPU resulted from a noise or the like by carrying out the ignition control during the rotation of an engine, and the receiving of a cord signal and the distinguishment of whether it is right or wrong during no rotation of the engine. SOLUTION: Whether an engine is rotating or not is distinguished, and in the case where the engine stops at the time of starting, whether a received cord signal coincides with a normal cord signal stored in an ID memory section 13 or not is distinguished, and in the case of their coincidence, a CPU 12 permits an ignition control to a CDI basic circuit section 14. On the other hand, in the case where the CPU 12 is brocken clown on account of the abnormality of a watch dog signal from the CPU 12 or the breaking down of a power source, the CPU 12 is reset and the engine being in rotation is confirmed. When the engine being in rotation is distinguished, second cord recognition process is unnecessary. Thus in the case of the instant turning off of the CPU during the rotation of the engine, which can return to the ignition control without carrying out the second cord recognition process for preventing the stop of engine ignition control.
