  • Publication number: 20240100862
    Abstract: Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.

  • Patent number: 11545165
    Abstract: This encoding device is able to encode an S signal efficiently in MS prediction encoding. An M signal encoding unit generates first encoding information by encoding a sum signal indicating a sum of a left channel signal and a right channel signal that constitute a stereo signal. An energy difference calculation unit calculates a prediction parameter for predicting a difference signal indicating a difference between the left channel signal and the right channel signal by using a parameter regarding an energy difference between the left channel signal and the right channel signal. An entropy encoding unit generates second encoding information by encoding the prediction parameter.

  • Patent number: 10085187
    Abstract: Provided is a base station that enables data communications in a small cell to continue even if a handover between macro cells occurs. In the base station (100), a handover determination unit (105) determines whether the handover of a control plane from the base station (100) to another macro cell is necessary for a terminal. If it is determined that the handover is necessary, a radio resource control unit (109) and a slave radio resource control unit (110) continue the control of a user plane communication process when the terminal is located inside a small cell, and the radio resource control unit (109) and slave radio resource control unit (110) stop the control of the user plane communication process and perform a process of handover to the other macro cell when the terminal is located outside the small cell.

  • Patent number: 10080247
    Abstract: Even when a terminal goes out of a macro cell, data communication in the small cell can be caused to continue while the mobile management in a macro cell is continued. When a first determination unit (205) determines that a terminal exists outside the cell of a base station (200), an existence recognition packet transmission/reception unit (207) transmits a recognition packet, which is used for recognition, to the terminal via a small cell, and thereafter receives a response to the recognition packet from the terminal via the small cell. When a second determination unit (206) determines, because of the reception of the response, that the terminal exits inside the cell of the base station (200), a radio resource control unit (204) causes the connection of the control plane between the terminal and the base station (200) to continue.

  • Patent number: 8352219
    Abstract: The object is to enable the calculation of load transfer paths in case of distributed load applied to the structure with the numerical structure-analysis calculation system. The value of the parameter U** at each point is calculated according to the ratio of the complementary strain energy U at the application of load without fixing the point in the structure and the complementary strain energy U? at the application of load with fixing one point in the structure. In the actual calculation, according to the complementary strain energy U, and the flexibility matrix CAC with respect to the loading point A and one point C in the structure, and the inverse matrix CCC?1 of the flexibility matrix with respect to point C, and the load pA at the loading point A, the value of the parameter U** (CACCCC?1CCApA·pA/(2U)) at point C is calculated.

  • Patent number: 7695353
    Abstract: In a grinding wheel in which abrasive tips for rough grinding and abrasive tips for finish grinding are alternately bonded to a periphery of a disk type base rotating about a rotation axis, each abrasive tip includes the abrasive layer formed by bonding abrasive grains and a lower layer overlaid and integrally for led with the abrasive layer. The abrasive tip is attached to the periphery of the base at the lower layer. A Young's modulus of the lower layer of the abrasive tip for finish grinding relative to a load acting on the grinding surface of the abrasive tip in an inward direction of the grinding wheel is less than that of the abrasive tip for rough grinding. Thereby, the surface of a workpiece can be both rough-ground and finish-ground with superhigh-precision surface roughness with using one grinding wheel.

  • Patent number: 6540286
    Abstract: According to a body structure of the present invention, a floor panel member is reinforced by a pair of first members, and the second member comprised of plural pipes is disposed along the width of a vehicle so as to integrate the first members. An end of the second member is extended along the longitudinal side of the vehicle and is fixed by welding in the state of penetrating into a side sill. There is no necessity of providing any reinforcement material because the second member has a high strength continuously along the width of the vehicle. Moreover, there is no necessity of increasing a board thickness for the purpose of securing the rigidity because the second member penetrates into the side sill. On the other hand, the second member can be manufactured by cutting an existing steel pipe to a predetermined side. It is therefore possible to cope with the change in the width of the vehicle only by changing a cutting size.
