摘要： A spool valve has a valve housing with a valve bore formed therein, a spool having a land portion slidably accommodated in the valve bore, a control port formed within the valve housing, able to communicate with the valve bore, and opened and closed by the land portion, and an annular groove open at an inner peripheral surface of the valve bore and communicating with the control port. Part of the control port is open over the inner and outer parts, as taken in the widthwise direction, of the annular groove. The degree of opening of the port is variably controlled by the displacement of the land portion.

摘要： An electromagnetic actuator includes a housing and a pair of stators cooperating with the housing to form a magnetic circuit for a solenoid. Each of the pair of stators has a tubular portion, and the tubular portions of the pair of stators have their one ends disposed in the opposed spaced relation to each other. The solenoid is mounted around the tubular portions of the pair of stators, and an armature is received in the tubular portions of the pair of stators so as to be movable along the axis of the tubular portions. The armature is supplied with a force when an electric current is applied to the solenoid. In order to keep the magnetic resistance of the magnetic circuit to a low level, one of the pair of stators is formed integrally with one end of a tubular body of the housing so that the housing and the one stator constitute a unitary member.

摘要： A winding roll lifting device is provided in which the base end side of a supporting arm (5), having a tip side installed rotatably on a hook part (34) of the lifting device (1), is installed on the upper side of a main body (2), and a base end (8b) of a chuck part (8a) to be inserted into a winding roll (30) is installed rotatably on the lower side of the main body (2). The supporting arm (5) is rotated about the upper side of the main body (2) in the direction approaching the chuck part (8a) in synchronization with the rotation of the chuck part (8a) about the lower side of the main body (2) by a drive mechanism of the main body (2) from vertical to horizontal state so as to raise the winding roll (30) from the vertical to horizontal state.

摘要： A shaft construction for use in winding or rewinding a web such as a strip of paper, a band of woven cloth, a sheet of metal, and the like around its paper-made core comprises a center hollow shaft having a longitudinal air passage through it, and a plurality of individual hollow expandable annular members mounted around the center hollow shaft and arranged adjacent to each other along the effective length of the center hollow shaft. The annular members are separated by an intervening spacer ring from the adjacent annular members, and each is internally communicative with the center hollow shaft for accepting a compressed air from the center hollow shaft. Each of the annular members engages and press against the paper-made core with a suitable pressure force for maintaining the coaxial relationships between each annular member and the paper-made core.
