摘要： In a hydrostatic continuously variable transmission in which a clutch valve capable of operating between a clutch-on position for setting a hydraulic closed circuit between a hydraulic pump and a hydraulic motor to a hydraulic transmitting state and a clutch-off position for setting the hydraulic closed circuit to a hydraulic transmission cutting-off state is connected to the hydraulic closed circuit, a pressure bearing chamber for urging the clutch valve to the clutch-off position, and a pressure regulating spring for urging the valve to the clutch-on position are provided in the clutch valve, and a clutch controller for regulating the set load of the pressure regulating spring is connected to the pressure regulating spring. Thus, the degree of the hydraulic transmission between the pump and the motor can be controlled as desired without influence of the viscous change of a working oil. The clutch valve is disposed at one axial end of a transmission shaft.

摘要： In a motorcycle with a pair of left and right steps mounted in a projecting manner on a lower portion of a vehicle body, a pair of left and right brake pedals capable of independently operating the rear wheel brake are pivoted on the vehicle body in close vicinity to the left and right steps, respectively. When a driver turns the motorcycle in either left or right direction with his one foot being placed on the ground, the driver can operate the rear wheel brake using the opposite foot.

摘要： A swashplate type variable displacement hydraulic device is so constructed that a plurality of plungers are slidably received in a plurality of cylinder bores arranged annularly around an axis of rotation, a back surface of a swashplate of which a fore surface is engaged by outer ends of the plungers is supported by a swashplate holder via bearing means, and a stationary swashplate anchor supports the swashplate holder to turn about a trunnion axis which intersects the axis of rotation at right angles. Opposing surfaces of the swashplate holder and swashplate anchor are formed as spherical surfaces of which a center is located at a position where the axis of rotation intersects the trunnion axis, the swashplate holder has a pair of trunnion shafts projected from opposite ends of the swashplate holder while extending along the trunnion axis, and the trunnion anchor is formed at opposite ends thereof with recesses with which the trunnion shafts are rotatably engaged.

摘要： In a swash plate type hydraulic system such as a hydraulic pump, a hydraulic motor of the like, a group of cylinder bores in which plungers engaging a swash plate are slidably received are annularly arranged in a cylinder block, and higher and lower pressure oil passages are concentrically provided in the cylinder block. Further, a group of distributor valves are provided in the cylinder block in a radially arranged configuration for controlling the connection and disconnection between the higher and lower pressure oil passages and the group of cylinder bores by radial reciprocating motion of the valves, and an eccentric wheel is provided eccentrically with respect to the center of rotation of the cylinder block to abut against the outer ends of the distributor valves so as to impart a reciprocating motion to each of the distributor valves. A shifting device is provided for changing the eccentric relationship between the eccentric wheel and the cylinder block.

摘要： A method of preparing and executing a sequence program for effecting the sequence control of a sequence controller for a machine tool by executing a subroutine program. A sequence diagram is prepared, which diagram expresses a function command for a subroutine as data divided into control conditions and parameters. From the sequence diagram a sequence program is prepared, which program includes a command for reading data indicative of a control condition, and parameter data of which a subroutine is informed. The sequence program so prepared is then executed.

摘要： A numerically controlled machine tool is equipped with a programmable sequence controller having a first storage area capable of storing operation commands, and a second storage area capable of storing a duplicate of the data planted in the first storage area without erasing the planted data. An operation command, when sent from a numerical control device to the machine tool, is stored in the first storage area and then, when the machine tool has completed the instructed operation, is read out from the first storage area and stored in the second storage area, this operation being repeated as each new command is issued. When electric power is connected to the machine tool, the data stored in the first and second storage areas is compared, an alarm being generated when the two sets of data do not agree.
