20130010451 | LASER DIODE MODULE - A laser diode module includes a laser diode, a Faraday rotator, and a polarizer. The laser diode outputs an output laser beam which is linearly polarized light and is placed in TE mode. The Faraday rotator is disposed on the optical axis of the output laser beam and rotates the polarization direction of incident light by 45°. The polarizer is disposed on the side adjacent to an optical fiber, of the Faraday rotator, and the direction of the transmission axis thereof agrees with the polarization direction of the output laser beam having passed through the Faraday rotator. No selection element configured to selectively transmit only a laser beam traveling in a particular polarization direction is disposed on the side adjacent to the laser diode, of the Faraday rotator. | 01-10-2013 |

20110172900 | Controller for Idle Stop System - When a request for re-start of an engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, an operation of starting by re-start of fuel injection and an operation of driving the starter overlap, and a problem is likely to occur in wear resistance and durability of a ring gear and a pinion gear. Further, since collision torque becomes large, a collision sound of the ring gear and the pinion gear and a mesh sound which occurs at the instant of connection are likely to occur. The present invention changes a method of starter drive based on a behavior of engine revolution after a request for re-start of the engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, and combustion recovery is implemented by an engine combustion recovery function, or an engine state or the like at the time of occurrence of change of mind, in a controller of a vehicle having an idle stop function. | 07-14-2011 |

20140196681 | ENGINE CONTROL APPARATUS - Upon gear disengagement, a pinion gear drive means actuates a pinion gear to disengage from a ring gear while the starter motor of a starting device is rotated or while injectors of an engine are caused to inject fuel into cylinders of the engine to ignite an air-fuel mixture therein, thereby releasing the gear disengagement. Applied to an idling stop-capable vehicle that engages the starter pinion gear with the engine ring gear beforehand to shorten the time to restart, the inventive control apparatus with the above feature releases unfailingly the engagement against metal-to-metal frictional force that causes the gears to be stuck with each other upon engine stop. | 07-17-2014 |
20140350827 | RESTARTING DEVICE OF INTERNAL COMBUSTION ENGINE - An automobile control device includes a function that can control drive torque of a starting device to an arbitrary value, and a positive rotation detecting unit having at least one of a function to detect whether an engine rotates positively and a function to detect whether the engine does not rotate reversely. The control device also has an idle stop function to increase the drive torque of the starting device when the positive rotation detecting unit detects that the engine rotates positively or does not rotate reversely. Accordingly, problems of malfunctions such as a reduction in a system voltage, abnormal wear of a brush in a starter motor, and breakage of a semiconductor switch are solved that are found in a conventional automobile control device having the idle stop function and that are caused by flowing of overcurrent when a starter is driven during swing-over that occurs immediately before engine stop. | 11-27-2014 |
20150144109 | Control Device for Internal Combustion Engine - A control device for an internal combustion engine is provided which can stabilize behavior when a fuel injection valve is opened, and reduce a variation in the amount of fuel injection of the fuel injection valve. A control device ( | 05-28-2015 |

20160047330 | Device for Controlling Fuel Injection Valve - An object of the invention is to reduce an injection quantity of minimum by reducing difference in machines of fuel injection valves and difference in injection quantities of fuel injection valves caused by difference in characteristics. A fuel injection valve drive unit includes a unit that individually sets drive current waveform profiles according to cylinders, and includes a unit that individually sets drive current waveform profiles of the fuel injection valves on the basis of identification information based on injection quantity characteristics of the fuel injection valves. | 02-18-2016 |
20160076498 | Electromagnetic Valve Control Unit and Internal Combustion Engine Control Device Using Same - Provided are an electromagnetic valve control unit and a fuel injection control device using the same that can precisely detect a change of an operating state of an electromagnetic valve, that is, a valve opening time or a valve closing time of the electromagnetic valve, precisely correct a drive voltage or a drive current applied to the electromagnetic valve, and appropriately control opening/closing of the electromagnetic valve, with a simple configuration. In an electromagnetic valve control unit for controlling opening/closing of an electromagnetic valve by a drive voltage and a drive current to be applied, the drive voltage and the drive current applied to the electromagnetic valve are corrected on the basis of a detection time of an inflection point from time series data of the drive voltage and the drive current when the electromagnetic valve is opened/closed. | 03-17-2016 |
