摘要： PROBLEM TO BE SOLVED: To provide an engine starting device 1 which can relax the shocks accompanying torque transmission on starting the engine and in the middle of cranking.
SOLUTION: When an engine starting signal is inputted, an ECU 3 gradually increases field magnetic flux by gradually increasing a field current energized to a shunt-wound coil 4c of a DC motor 4. After that, a battery current is energized to a series-wound coil 4b and an armature 4a by turning ON an electromagnetic switch 5 (the energization to an exciting coil 5c). By this, the output torque of a starter is not drastically risen. The output torque is gradually increased together with the increase of the field magnetic flux. Accordingly, the generation of shocking torque can be suppressed during the energization to the DC motor 4. Large shocks are not applied to a torque transmission mechanism. As a result, the reliability of the starter can be secured.

摘要翻译：要解决的问题：提供一种发动机启动装置1，其可以在起动发动机和起动中途时放松伴随转矩传递的冲击。解决方案：当发动机启动信号被输入时，ECU3通过逐渐增加通向直流电动机4的并联线圈4c的励磁电流来逐渐增大励磁电流。此后，电池电流被激励绕组线圈4b和电枢4a通过接通电磁开关5（激励到励磁线圈5c）。由此，起动器的输出转矩没有急剧上升。随着场磁通量的增加，输出转矩逐渐增大。因此，在对直流电动机4的通电期间可以抑制冲击转矩的产生。对转矩传递机构不施加大的冲击。结果，能够确保起动器的可靠性。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To highly accurately detect a rotation state of a DC motor regardless of the rotation speed while preventing torque fluctuation without providing a sensor such as an encoder. SOLUTION: A soft magnetic protrusion 13 is provided on the inner peripheral face of a housing 10 of a motor 2. An air gap between a rotor core 20 and the housing 10 (including the protrusion 13) is changed by the protrusion 13 along with the rotation of the rotor core 20. Therefore, the magnetic resistance of the motor 2 is also changed, thereby changing an inductance between brushes 18, 19 of the motor 2 along with the rotation. On the other hand, a driving DC voltage is applied to the motor 2 from a DC power supply 6, however, an AC voltage from an AC component generating part 7 is superposed on the DC voltage. Consequently, the amplitude of an AC component included in a current flowing in the motor 2 is changed along with the rotation of the motor 2. A rotation-signal detecting part 4 generates a rotation pulse on the basis of amplitude changes of the AC component included in a conduction current. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a processing device capable of storing data for engine control every constant period of time in a data collection term in a memory without failure. SOLUTION: A microcomputer has parallely operable chA0 and chA1 as a DMA channel for sequentially DMA-transferring data every constant period after signals from a cylinder inner pressure sensor are A/D converted every constant period of time and processed with a digital filter, and an upper limit (in this example, 255) of a number of data capable of being continuously transferred after starting is defined to each of DMA channels. In this microcomputer, in a data collection term, operation terms of chA0 and chA1 are overlapped with each other and chA0 and chA1 are sequentially started, so as to store the data every constant period in a memory. Then, after the data collection term is completed, one of same data simultaneously transferred by two DMA channels is found from the data stored in the memory, and deleted.

摘要： PROBLEM TO BE SOLVED: To provide an engine starter capable of enhancing the starting performance of an engine.
SOLUTION: A motor circuit 6 is connected with a circuit 10 for bypassing a series coil 2b and provided with an element 11 for controlling a bypass current. A line 7 being connected from a start switch 9 to a shunt coil 2c is provided with an element 12 for controlling the current quantity of the shunt coil 2c. The control element 11 is controlled to increase the conduction quantity as the r.p.m. increases from 100% off state and 100% on state is brought about upon elapsing a specified period t2. On the other hand, the control element 12 is held constantly in 100% on state. Since the series coil 2b is short-circuited upon elapsing the specified period t2 and wiring resistance of the series coil 2b is nullified, armature voltage can be maximized and motor capacity can be exhibited to the maximum during high speed rotation.
