20140052349 | SHOVEL, MONITORING DEVICE OF THE SAME AND OUTPUT DEVICE OF SHOVEL - A temporary storage device temporarily stores image data acquired by an imaging device. Each of a plurality of sensors detects a plurality of physical quantities relating to an operation state of a shovel. A control device performs an operation abnormality determination based on detection values detected by the sensors. When an operation is determined to be abnormal, the control device transmits the image data, which corresponds to a period from a first time prior to a time at which the operation is determined to be abnormal to at least the time at which the operation is determined to be abnormal, from the temporary storage device to the abnormality information storage device. Therefore, it is easy to specify a cause of abnormality of the operation state of the shovel. | 02-20-2014 |

20140338316 | REGENERATION CIRCUIT FOR HYDRAULIC MOTOR, CONSTRUCTION MACHINE INCLUDING REGENERATION CIRCUIT, AND METHOD OF CONTROLLING REGENERATION CIRCUIT - A regeneration circuit includes an oil collection passage that collects return oil from a hydraulic motor to which pressure oil discharged from a hydraulic pump is supplied, a regeneration system that recovers energy from the collected return oil, and an oil resupply passage that resupplies pressure oil from the regeneration system to the hydraulic motor. The regeneration system includes a pressure oil inflow part that converts pressure energy of the collected return oil into mechanical energy, a pressure oil outflow part that outputs low pressure oil with a pressure lower than a pressure of the collected return oil to the oil resupply passage when the pressure energy of the collected return oil is converted into the mechanical energy, and a regeneration part that accumulates the mechanical energy. | 11-20-2014 |
20140366717 | FLUID PRESSURE INCREASING/DECREASING MACHINE AND WORKING MACHINE - A fluid pressure increasing/decreasing machine can continuously supply an output pressure to a destination of supply by converting an input pressure from a source of supply. A control device selects at least one input pressure chamber and at least one output pressure chamber from among at least three pressure chambers in a fluid pressure cylinder or a plurality of fluid pressure cylinders operating inter-connectedly, the input pressure chamber being supplied with the input pressure, the output pressure chamber creating the output pressure including a pressure higher than the input pressure and a pressure lower than the input pressure. A flow control valve causes the selected input pressure chamber to communicate with the source of supply, and the selected output pressure chamber to communicate with the destination of supply. At least one of the pressure chambers is capable of being either of the input pressure chamber and the output pressure chamber. | 12-18-2014 |

20150109569 | LIQUID CRYSTAL DISPLAY DEVICE - An object of the present invention is to realize a liquid crystal display device having a photo-aligned alignment film in which the alignment film is overlapped with a seal material to downsize a frame area, and the reliability of a seal portion can be secured. A first alignment film and a second alignment film are overlapped with a seal material, the first alignment film and the second alignment film are made of material containing 0.5 wt % or larger and 2 wt % or smaller of an amine-system silane coupling agent, and the shrinkage ratio and the storage elastic modulus of the seal material evaluated using the modulus of volume change by a specific gravity cup method are 5.1% or smaller and 9.2 Pa or smaller, respectively. Accordingly, a frame area can be downsized, and the reliability of a seal portion can be maintained. | 04-23-2015 |
