Abstract: A ram driving method including the steps of fixing one end of a large-diameter piston rod integral with a large-diameter piston reciprocably included in a large-diameter cylinder attached integrally to a ram to a fixing unit, connecting one end of a small-diameter piston rod integral with a small-diameter piston reciprocably included in a small-diameter cylinder integral with the large-diameter cylinder to a moving member moved by a motor driving, integrally moving the small-diameter cylinder and the small-diameter piston and communicating a first compartment and a second compartment of the large-diameter cylinder divided by the large-diameter piston with each other, moving the ram integrally with the small-diameter piston rod moved by the moving member, and communicating the small-diameter cylinder with the large-diameter cylinder, thereby moving the large-diameter cylinder with a strong force by a working fluid supplied from the small-diameter cylinder.

Abstract: A navigation system comprises an image display unit at which various images including a map are displayed, a touch panel operation detection unit that detects a touch panel operation performed by a user based upon a contact position at which the user has touched the image display unit, a specified road detection unit that detects a road segment specified by the user by tracing a corresponding road portion present in the map, based upon a locus of the contact position resulting from the touch panel operation detected by the touch panel operation detection unit, and a route setting unit that extends the detected road segment along a direction in which the road portion has been traced by the user and sets the extended road segment as a route to follow.

Abstract: A ram driving method including the steps of fixing one end of a large-diameter piston rod (5R) integral with a large-diameter piston (5P) reciprocably included in a large-diameter cylinder (5) attached integrally to a ram (3) to a fixing unit (9), connecting one end of a small-diameter piston rod (7R) integral with a small-diameter piston (7P) reciprocably included in a small-diameter cylinder (7) integral with the large-diameter cylinder to a moving member (17) moved by a motor driving, integrally moving the small-diameter cylinder and the small-diameter piston and communicating a first compartment (5A) and a second compartment (5B) of the large-diameter cylinder divided by the large-diameter piston with each other, moving the ram integrally with the small-diameter piston rod moved by the moving member, and communicating the small-diameter cylinder with the large-diameter cylinder, thereby moving the large-diameter cylinder with a strong force by a working fluid supplied from the small-diameter cylinder.
