  • Patent number: 9481235
    Abstract: A control device performs a control process such that when there is a request in a series/parallel mode to switch the current mode to a parallel mode, and the current speed ratio also has a value faster than a Lo rotation synchronization speed ratio, the control device performs the step of switching the running mode to the parallel mode via a series mode with asynchronous switching, whereas when the current speed ratio has a value slower than the Lo rotation synchronization speed ratio, the control device performs the step of switching the running mode to the parallel mode via the series mode with synchronous switching.

  • Publication number: 20140174706
    Abstract: A thermal conductive stress relaxation structure is interposed between a high-temperature substance and a low-temperature substance to conduct heat in a heat-transfer direction from the high-temperature substance to the low-temperature substance. The structure includes an assembly configured such that a thermal conductive material gathers in a non-bonded state having stress relaxation effect. Such an assembly is a rolled-up body configured such that a carbon-based sheet material and a metal-based sheet material are alternately rolled up, for example. This structure has one or more interfaces at which adjacent parts can slide, thereby dividing a deformable region to relax the thermal stress. It has a low rigidity and can thus deform to release the thermal stress. The structure can suppress the thermal stresses and the shape changes that would be generated in the high-temperature substance and the low-temperature substance, and each physical body located there between.

  • Publication number: 20100235063
    Abstract: A hybrid vehicle (1) includes a rotation speed sensor (7) for detecting speed of rotation (Nm) of a motor generator (MG2). Fluctuation of the rotation speed (Nm) of the motor generator (MG2) reflects fluctuation of a first torque generated in a power transmitting member including a drive shaft (8). Hybrid vehicle (1) further includes a controller (30) for controlling a second torque transmitted from motor generator (MG2) through a rotation shaft of motor generator (MG2) to the power transmitting member, based on the speed of rotation (Nm) detected by rotation speed sensor (7). If the first torque is a vibration torque that fluctuates to cause the rotation shaft of motor generator (MG2) to rotate in positive and negative directions, controller (30) controls the second torque such that difference between absolute values of maximum value and minimum value of the vibration torque becomes smaller.

  • Patent number: 7753821
    Abstract: A composite gear member of the power transmission device is divided into an annular first member and a second member. The annular first member is formed with an output gear. The second member is formed with internal teeth and spline-coupled to an inner portion of the first member. Therefore, the influence of the engagement reaction force generated from the output gear of the first member is decreased by the spline-coupling, and the vibration is reduced.

  • Publication number: 20060015015
    Abstract: A medical data warning notifying system and method for notifying a hospital only when there is abnormal data in medical data entered by a patient on peritoneal dialysis at home. In the medical data warning notifying system, a patient terminal used by a patient, a server for controlling data exchanged between the patient and a hospital, and a hospital terminal used by a doctor are interconnected over a network. The server receives medical data entered through the patient terminal, stores the received medical data, and judges from the received medical data whether or not there is any abnormal data. If it is judged that abnormal data is included, a warning signal is sent to the hospital terminal. A message created on the hospital terminal is relayed and sent to the patient terminal.
