20090026646 | INJECTION MOLDING MACHINE, AND METHOD FOR ADJUSTING A REVERSE ROTATION AMOUNT OF A REVERSE ROTATION PROCESS IN AN INJECTION MOLDING MACHINE - When a resin passage of a check ring is opened, resin backflow occurs during time when an injection screw is moved forward, and a reverse rotational force is applied to the screw by resin backflow. On the other hand, when the resin passage is closed, there is no resin backflow and the reverse rotational force applied to the screw is greatly reduced. Consequently, after completion of metering process and before injection process, the screw is moved forward after the screw has been rotated in reverse a predetermined amount to prevent resin backflow. At this time, a maximum value of the reverse rotational force applied to the screw is detected. Until the detected maximum reverse rotational force reaches a reference value or less, the reverse rotation amount is increased sequentially and respective molding cycles are carried out. When the detected maximum reverse rotational force reaches the reference value or less (passage closure), the reverse rotation amount at this time is set as the reverse rotation amount for the reverse rotation process. By means of this operation, an optimal reverse rotation amount can be adjusted automatically. | 01-29-2009 |

20080199551 | INJECTION MOLDING MACHINE - An injection molding machine capable of accurately detecting a rotational force exerted on a screw by resin backflow to easily evaluate states of resin backflow and closure of a check valve. In a state where the screw is stopped axially and rotationally after metering is finished, a load exerted on the screw in the rotational direction is detected. This load is a rotational force exerted on the screw from resin remaining between flights of the screw (resistance torque component). During injection, a load T exerted on the screw in the direction of rotation is detected, and the resistance torque component is subtracted from the detected load T to obtain a backflow torque component generated by resin flowing back through the check valve. By simultaneously displaying waveforms of backflow torque components in a plurality of molding cycles to be overlapped, stability of closure of the check valve is readily evaluated. | 08-21-2008 |

20090045560 | Engine natural vibration frequency detection method, active vibration isolation support device control method, engine natural vibration frequency detection apparatus, active vibration isolation support device control apparatus, active vibration isolation support device, and vibration frequency detection apparatus for vibrating body - The natural vibration frequency of a roll resonance which does not occur since the engine rotation number is high in a normal operation range of an engine is detected at the time of engine start or stop when the engine rotation number is lower than the normal operation range, and thus the natural vibration frequency of the roil resonance can be detected with a good accuracy. A current is generated by an electromotive force of an actuator of the active vibration isolation support device excited by the engine immediately before stopping its rotation, and the frequency of the current is used to detect the natural vibration frequency of the engine, and the roll resonance of the engine is suppressed by controlling the operation of the active vibration isolation support device at the time of engine start based on the natural vibration frequency, thereby not only eliminating the need of a specific frequency detection sensor, but also effectively reducing the vibration at the time of engine start when the roll resonance becomes strong. | 02-19-2009 |

An engine-mounted controller of a vehicle determines whether or not an engine is in a completely stopped state when an idle-stop operation is canceled. If the controller determines that the engine is in a completely stopped state, a first control operation for suppressing the transmission of engine vibrations associated with engine idling is executed on the assumption that the engine is in a completely stopped state, and if the controller determines that the engine is not in a completely stopped state, the first control operation is prohibited when the engine restarts. | 06-04-2015 |
