| 20100288221 | INTAKE DEVICE FOR MULTI-CYLINDER INTERNAL COMBUSTION ENGINE - An intake passage in an internal combustion engine includes an independent passage disposed in each of cylinders, and a common passage connected to the independent passage, to be commonly used by the different cylinders. A cross-sectional area of the independent passage disposed in the cylinder having the long passage length from an intake valve to a surge tank is made greater than that of the independent passage disposed in the cylinder having the short passage length. | 11-18-2010 |

| 20090194044 | ELECTRIC SUPERCHARGER - An lubricating oil from an oil pump that is driven by rotation of an engine is supplied as a refrigerant to a rotor of an assist motor via a pressure valve. The pressure valve is configured to be closed when the pressure of the lubricating oil is less than a predetermined value, and to open when the pressure of the lubricating oil is greater than or equal to the predetermined value. As a result, when the rotor is in low need for cooling down because the temperature rise of the rotor is small although the rotation speed of the rotor rises, that is, when the engine is operating at a low rotation speed with a high load, the supply of lubricating oil to the rotor is reduced or stopped. | 08-06-2009 |
| 20100235069 | APPARATUS FOR CONTROLLING A VEHICLE - It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine includes an impulse valve common to all the cylinders arranged in the engine. The impulse valve is arranged in a communicating tube provided at the downstream side of a serge tank. An ECU executes impulse valve drive control. In the control, the ECU judges whether a rotation angle sensor which detects the open degree of the impulse valve has failed. If it is judged that the rotation angle sensor has failed, the ECU controls a drive motor and a drive circuit for driving a valve body so that a valve body of the impulse valve rotates inside the communicating tube. Here, the rotor of the drive motor which defines the rotation speed of the valve body has an rpm which is set in accordance with the mechanical rpm NE of the engine. | 09-16-2010 |

| 20080218930 | Control Apparatus and Control Method of Electromagnetic Drive Valve Operating Mechanism - When a target valve timing determined in accordance with the state of operation of an internal combustion engine is acquired, a feed forward control of setting a command timing of a valve body on the basis of the target valve timing and a predicted delay time is performed, and a feedback control of setting the actual delay time in the previous cycle as a predicted delay time for the next cycle is performed. The valve timings (opening, closure) are specified at a timing at which the valve body reached a position that is apart from a pre-determined position on a basis of a buffer height of a buffer mechanism. This makes it to possible to accurately detect the actual delay time in the feedback control, and allows the command timing to be properly set in the feed forward control. | 09-11-2008 |
| 20090114863 | Electromagnetically driven valve - An electromagnetically driven valve includes a drive valve with a stem; a lower disk and an upper disk, each of which can oscillate by using a predetermined point in a disk base as a supporting point, each of which is movably connected to the stem at a first end and is movably supported by the disk base at a second end, and which are provided at a predetermined distance from each other; an electromagnet includes an open/close coil provided between the lower and upper disks; and a detector coil which detects a position of at least one of the drive valve, the lower disk, and the upper disk. The electromagnetic force is applied to the lower and upper disks when an electric current passes through the open/close coil. An amount of electric current that passes through the open/close coil is determined based on the position of the drive valve. | 05-07-2009 |
| 20090266318 | SLIDING MODE CONTROL APPARATUS AND ADJUSTING METHOD - A sliding mode control apparatus. When displacing a controlled object to which an urging force is applied by an elastic member from one displacement end to the other displacement end, the control apparatus sets a switching hyperplane and controls the controlled object by using a sliding mode control in such a manner that a state quantity of the controlled object is converged on the switching hyperplane. In the sliding mode control, the control apparatus switches an operation mode for controlling the controlled object when the controlled object passes an operation switching point. The control apparatus detects disturbance in the sliding mode control and a change with time of the elastic member, and changes the operation switching point in accordance with both of the detected disturbance and the detected change with time. | 10-29-2009 |

| 20110113898 | PIEZOELECTRIC VIBRATION TYPE FORCE SENSOR - In a piezoelectric vibration type force sensor according to the present invention, vibration is restricted by a friction force between a piezoelectric body and a restricting member, and hence a range of sensing forces can be expanded compared with a case in which the vibration is restricted directly from a direction that is the same as an vibration direction. A conventional structure, in which a lead wire is soldered directly for electrically connecting the piezoelectric body to an external control circuit, causes a restriction of the vibration due to a solder attached to the piezoelectric body, resulting in narrowing the sensing range. Using the piezoelectric vibration type force sensor, the range of sensing forces can be expanded by making a state in which conducting portions of the piezoelectric body and the restricting member are not fixed but contact with each other for keeping electric conductivity. | 05-19-2011 |

| 20110264358 | ENGINE SYSTEM - An engine system includes: a mixture portion capable of mixing a first liquid as a main fuel with a second liquid at a predetermined mixture ratio; an engine to which a mixed fuel produced by mixing the first liquid with the second liquid is fed from the mixture portion; and a control portion controlling the mixture ratio of the mixed fuel to be a target mixture ratio based on a driving state of the engine. The control portion controls the target mixture ratio based on a feeding period from the time when the mixed fuel is fed from the mixture portion to the time when the mixed fuel arrives at the engine. | 10-27-2011 |
