20090152050 | Lubrication monitoring device and method, and rolling bearing assembly - A lubrication monitoring device monitors a lubricating condition of a lubricator feeding an oil droplet at a predetermined time interval by means of a discharge nozzle having a nozzle orifice. The lubrication monitoring device comprises: a pair of electrodes disposed in the proximity of the nozzle orifice; a capacitance detecting portion for detecting the variation of capacitance between the pair of electrodes, the capacitance varying in conjunction with the varying amount of oil fed from the nozzle orifice to space between the pair of electrodes; and a determination portion for determining whether the oil droplet is fed at the predetermined time interval or not, the determination made based on the detection result supplied from the capacitance detecting portion. | 06-18-2009 |
20110098888 | MOTOR CONTROL DEVICE AND VEHICLE-STEERING DEVICE COMPRISING SAME - A motor controller controls a motor including a rotor and a stator opposed to the rotor. The motor controller includes an electric current driving unit which drives the motor with an axis electric current value defined in a rotating coordinate system defined with respect to a control angle that is a rotation angle for control, a control angle computing unit which computes a current value of the control angle by adding an addition angle to a previous value of the control angle in each predetermined computing cycle, and an addition angle computing unit which computes the addition angle according to a torque to be generated by the motor or a response of the motor to the axis electric current value. | 04-28-2011 |

20100227721 | ENDLESS METAL BELT - An endless metal belt including a ring formed by laminating endless metal plates; and multiple elements continuously attached to the ring. Each of the elements has a body, a head connected to the body by a pillar, and slots formed between the body and the head on left and right sides of the pillar, respectively, for receiving the ring. The elements satisfy the equations (h/t)<1 and (S/h)>40, where h is a width of the slots, t is a plate thickness of the elements, and S is an area of the head. | 09-09-2010 |
20130089453 | VEHICULAR INTERNAL GEAR TYPE OIL PUMP - An oil pump includes a first spill passage formed on a side surface ( | 04-11-2013 |
20130170953 | VEHICULAR POWER TRANSMITTING SYSTEM - A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced. | 07-04-2013 |
