Abstract: Many vehicles designed for running on rough terrain include an automatic transmission for performing speed change by connecting or disconnecting an oil hydraulic clutch provided alongside each speed change gear. However, depending on the posture of the driver, it may be impossible to step on the brake. As a result, it may be impossible to achieve creep prevention with a creep preventive mechanism dependent on a brake signal. Therefore, a creep preventive mechanism which operates independently from a brake signal is required. The present invention provides an oil pressure control system operating independently from a brake signal. The system includes an oil pressure supply source with a linear solenoid valve for supplying working oil or interrupting the supply of the working oil to the oil hydraulic clutches. The supply of the working oil to the clutches is interrupted when the vehicle is stopped under an idling condition of an engine.

Abstract: An oil passage extending from an oil pump to a discharge port in an internal combustion engine is, at its halfway point, branched into at least two oil passages, for example, a first oil passage and a second oil passage. One of the at least two branched oil passages, for example, the second oil passage is provided with a restricting portion configured as a first orifice for restricting a flow amount of oil by reducing a diameter of the first orifice. A bypass valve is provided which acts, when a hydraulic pressure in the second oil passage exceeds a specific value, to bypass the first orifice so as to increase the flow rate of oil. It is possible to increase the hydraulic pressure at the time of low speed rotation up to a necessary pressure only by providing the restricting portion, without enhancing the performance of the oil pump.

Abstract: A method of preventing a nozzle or nozzles from dropping in a component mounting apparatus include gripping the nozzle structures with pivotal levers that are biased to a closed position. The pivotal levers are released after activation of the nozzles to permit appropriate movement for picking up, inspecting, orientating and locating electronic components on a substrate with the nozzles. During the operation of the mounting head, the levers are maintained in a release position against a biasing force and at the end of the operation, the biasing force can then cause the levers to close and support the nozzles in a gripping manner.

The continuously variable hydrostatic transmission shifts gears by changing the inclination angle of a movable swashplate provided for the variable displacement the hydraulic motor. The continuously variable hydrostatic transmission may perform a correction control, where the movable swashplate is moved to the TOP side, and the maximum value of the shift amount is obtained.
