Abstract: A method for managerial clerk inspection in an on-line system comprising a plurality of regular clerk terminal units operated for transactions by regular clerks, a terminal unit dedicated to a managerial clerk and operated by the managerial clerk for acknowledgement of transactions, a central unit and a terminal control unit interposed between the central unit and the regular clerk terminal units as well as the managerial clerk terminal unit. When the regular clerk operates the regular clerk terminal unit, a transaction message is transmitted from the regular clerk terminal unit to the central unit, and the central unit decides whether the transaction requires acknowledgement by the managerial clerk.

Abstract: An improved rotary pump designed to ensure a high pumping efficiency and delivery pressure without any unfavorable pulsation thereof. The pump includes a pump shaft drivably coupled to a prime mover and provided with a groove having a bottom surface extending in parallel with the axis of said shaft, and an eccentric rotor received in a cylindrical chamber for pumping of fluid and arranged to surround through a bearing said pump shaft for eccentric movement relative to said pump shaft while keeping a sealing contact with the wall of said cylindrical chamber. One or more wedge roller is disposed between said groove bottom surface and said bearing for effective power transmission from said pump shaft to said eccentric rotor. Between the cylindrical chamber wall and said eccentric rotor, there is formed a pump chamber which is sealingly divided by a partition member into a suction chamber and a delivery chamber.
