A multi-refill writing instrument includes a barrel, writing bodies accommodated in the barrel so as to be movable back and forth, elastic bodies urging the writing bodes backward, operating bodies connected to rear ends of the corresponding writing bodies and window holes formed in a side wall of the barrel so as to extend in the axial direction. The operating bodies protrude from the barrel to an outside through the window holes in the radial direction, one of the operating bodies slides forward along the window hole so that a nib of the writing body connected to the one operating body protrudes from the barrel through a front hole, and a nib of another writing body in a protruding state is retracted into the barrel, and the writing bodies and the operating bodes are pulled out from the barrel and inserted into the barrel.

There is disclosed a roller burnishing apparatus including a first member moved relative to an object to be burnished, a second member movable relative to the first member in a relative movement direction, a burnishing roller held by the second member such that the burnishing roller is rotatable, a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction, and a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device.

A multifunctional apparatus control system includes a multifunctional apparatus an authentication information input device, an I / F converter, and a control server. The control server includes: a UI control section which transmits, to the multifunctional apparatus over a network, data of authentication screen which prompts the user to make preparations for causing the authentication information input device to acquire authentication information; an authentication information input device driver which controls the operation of the authentication information input device over the network and receives, over the network, the authentication information that the authentication information input device has acquired; an authenticating section which performs authentication based on the authentication information that the authentication information input device driver has received; and a device control section which permits the multifunctional apparatus to execute the job, in accordance with the authentication result of the authenticating section. This arrangement makes it possible to construct a flexible authentication system.

A pallet arrangement for a people mover includes a plurality of pallets arranged one after the other to form a track. Each pallet comprises a pallet body, at least one surfacing element attached to the pallet body and a fastening mechanism to attach the at least one surfacing element to the pallet body. The fastening mechanism comprises at least one coupling element included in each surfacing element of the pallet, a form-locking groove included in the pallet body of the pallet and a locking element performing a locking operation with a locking movement and a releasing operation with a releasing movement. The locking element acts on all the coupling elements in the form-locking groove of the pallet body substantially simultaneously during the locking movement and the releasing movement.

In a brushless wiper motor, a rotor (33) is rotatably provided inside a stator (32) provided with a coil (32b), one end side of a rotation shaft (34) in the axial direction is fixed to the axial center of the rotor (33), a worm (35) is provided on the other end side of the rotation shaft (34) in the axial direction, the first and second bearings (36, 37) are respectively provided on one end side of the rotation shaft (34) in the axial direction and the other end side of the rotation shaft (34) in the axial direction than the worm (35) of the rotation shaft (34), the rotation shaft (34) is rotatably supported by only the first and second bearings (36, 37), and with the position of the first bearing (36) being defined as a reference position, a length thereof in the axial direction to the second bearing (37) is longer than a length thereof in the axial direction to the rotor (33). Since a commutator and other parts are not provided on a free end side of the rotation shaft (34), it is possible to provide a brushless wiper motor reduced in length of the rotation shaft (34), and reduced in inertial mass of the free end side of the rotation shaft (34).

A center pipe is used in a plasma torch for plasma cutting including a base portion and an electrode. The center pipe is inserted into the electrode and supplies cooling water into the electrode. The center pipe includes a pipe body and a contact piece. The pipe body is electrically connected to an electrical power source outside of the plasma torch via the base portion. The pipe body includes a cooling water channel therein. The pipe body is formed with an electrically conductive body. The contact piece is provided on the external circumferential surface of the pipe body and energizes the electrode through contact with the internal circumferential surface of the electrode. The contact piece has elasticity to produce a counterforce when pressed in the radial direction of the pipe body. The contact piece is formed with an electrically conductive body.

The invention relates to a valve for controlling fluids, having a piezoelectric unit (4) for actuating a valve member (3), with which a valve closing member (12) is associated that divides a low-pressure region (16) at system pressure from a high-pressure region (17). The valve member (3) has at least one first piston (9) and one second piston (11), between which a hydraulic chamber (13) is embodied. To compensate for leakage losses, a filling device (23) is used, which can communicate with the high-pressure region (17) and which has at least one channel-like hollow chamber (24), in which a solid body (25) is disposed, with a gap surrounding it, in such a way that on one end (25A) of the solid body (25), a line (26) branching off from the high-pressure region (17), and on its opposite end (25B) a leakage line (27) discharges into the hollow chamber (24), and that a line (29) leading to the hydraulic chamber (13) branches off along the length of the solid body (25), and the system pressure (p_sys) in the hydraulic chamber (13) is adjustable by geometric definition of the branching point (28) (FIG. 1).
