Abstract: An object of the present invention is to avoid unnecessary accumulation of a correction value during feedback control, even when a secondary pressure control valve enters a state of failure. A continuously variable transmission comprises a primary pulley supplied with a primary pressure that has been adjusted via a primary pressure control valve, a secondary pulley supplied with a secondary pressure that has been adjusted via the secondary pressure control valve, and a drive belt wound around the two pulleys. When a failure such as a disconnection occurs in the secondary pressure control valve, a lower limit value Imin of a target gear ratio is raised to a low side by a CVT control unit, and a setting region of the target gear ratio is set in a low region in which control is possible even during a failure. In so doing, divergence between the target gear ratio and an actual gear ratio can be avoided, and therefore unnecessary accumulation of the correction value during feedback control can be avoided.

Abstract: The instant invention describes a zipper lubricating applicator device for dispensing a lubricant to one or more components of a zipper. The applicator device is designed to fit various lubricant reservoirs and is capable of dispensing lubricant in the form of liquids, gels, or aerosols. The zipper lubricating applicator device contains a lubricant receiving cavity constructed and arranged to receive a lubricant reservoir. A lubricant dispensed from the lubricant reservoir is received by the lubricant receiving cavity and is directed to at least one inner lumen. The inner lumen provides a pathway for dispersal of a lubricant from the lubricant reservoir receiving cavity to a zipper receiving channel. The lubricant is dispersed at a controlled rate and to a desired portion of a zipper through the zipper receiving channel. The zipper receiving channel is constructed and arranged to provide dispensing of the lubricant to a portion of the zipper as the applicator device slidably moves upon the zipper track.

Abstract: When performing kick down, during re-acceleration after decelerating, the engine sometimes races unnecessarily, and a smooth acceleration feeling is not obtained. During control by a kick down mode, when accelerating after a throttle has been fully closed, a control target value is set so as not to pass to a Low side of a limit value of the control target value used during re-acceleration. As a result, racing of the engine is inhibited.

Abstract: An oil scavenge system of a gas turbine engine in accordance with one embodiment of the present invention, comprises a housing defined about an axis of rotation, the housing confining an air/oil mixture in motion within the housing and defining an oil scavenge area below the axis of rotation.

Abstract: A transmission has a rotating shaft, a coupling sleeve fixedly coupled to the rotating shaft to rotate with the rotating shaft and a variable speed gear mounted on the rotating shaft. The variable speed gear is configured to rotate on the rotating shaft when a clutch gear that is embedded in a side surface of the variable speed gear is disengaged from the coupling sleeve and to be fixed to the rotating shaft when the clutch gear is engaged from the coupling sleeve. The coupling sleeve is moved in the axial direction between the engaged and disengaged states by a shifting fork F3. A lubricant supplying structure directs lubricant to the clutch gear by diverting the lubricant against a side surface of the shifting fork that faces the clutch gear and a side surface of the coupling sleeve that faces the clutch gear.
