摘要： A transmission has a movable transmission part movably connected to a fixed transmission part via a shaft to undergo pivotal movement relative to the fixed transmission part about an axis of the shaft. Each of the transmission parts has a hollow cylindrical connecting portion through which the shaft extends. One of the connecting portion of the movable transmission part and the connecting portion of the fixed transmission part is received in the other of the connecting portions with a single seal member disposed therebetween so that an internal space of the fixed transmission part and an internal space of the movable transmission part communicate with each other to thereby form a single hermetically-sealed space for holding therein a lubricating oil.

摘要： Image information apparatuses, methods, and programs acquire image information of a plurality of frames of images sensed at predetermined regular time intervals. The apparatuses, methods, and programs detect a leading and trailing end of a lane mark included in a detection area defined in each frame of the image information. The apparatuses, methods, and programs detect a detected distance from one of the leading and trailing end of the lane mark to the other one as a detected distance based on the speed of the vehicle and the number of frames between a frame in which one of the leading end and the trailing end of the lane mark is detected and a frame in which the other one of the leading end and the trailing end of the lane mark is detected and determine a lane mark type of the lane mark on the basis of the detected distance.

摘要： A walk-behind working machine has a drive source, wheels rotationally driven by the drive source, and a traveling clutch for transmitting driving power from the drive source to the wheels. A driving member is disposed in the case and has a first friction surface. A driven member is mounted in the case for undergoing rotation relative to the driving member and has a second friction surface positioned to be brought into surface contact with the first friction surface at a preselected surface pressure. A characteristic curve of the traveling clutch plotted in a coordinate system including a vertical axis representing a coefficient of friction between the first and second friction surfaces and a horizontal axis representing a parameter obtained by dividing by the preselected surface pressure a product of a viscosity of the lubricating oil and a number of times the driven member rotates relative to the driving member per second has a first straight line and a second straight line connected to the first straight line via a bent point. The preselected surface pressure is determined so that the bent point corresponds to a switch point when the working machine is switched from a first state in which the walk-behind working machine operates at a high load to a second state in which the walk-behind working machine operates at a low load.

摘要： A ball and piston valve for controlling the flow of hydraulic fluid to a motive means have the ball and piston spring biased in opposing directions and with both initially subject to a first hydraulic fluid pressure that allows the springs to cause the ball to be unseated from its seat whereby fluid is directed to a fluid tank and wherein the ball is of sufficiently larger diameter than the piston that upon an increase in fluid pressure the ball is seated and remains seated when the pressure drops to the first hydraulic fluid pressure whereby the motive means to which the fluid is directed when the ball is seated does not have a sudden lurch upon a subsequent increase in pressure.

摘要： A hydrostatic continuously variable transmission includes a closed hydraulic circuit comprising a hydraulic pump, a hydraulic motor, and an oil supply passage connected between the hydraulic pump and the hydraulic motor. The hydraulic pump selectively generates a first oil pressure lower than a first predetermined pressure level, a second slowly-changing oil pressure higher than the first predetermined pressure level when the transmission is in normal operation, and a third rapidly-changing oil pressure higher than a second predetermined pressure level higher than the first predetermined pressure level when the transmission starts to operate. The transmission also includes a first pressure-responsive valve for connecting the oil supply passage to the oil tank in response to the first oil pressure applied through the oil supply passage, and disconnecting the oil supply passage from the oil tank in response to the second oil pressure applied through the oil supply passage, and a second pressure-responsive valve for connecting the oil supply passage to the oil tank in response to the third oil pressure applied through the oil supply passage, and disconnecting the oil supply passage from the oil tank in response to the second oil pressure applied through the oil supply passage.
