There are provided a vibrator and an electronic device including the same, the vibrator including a housing having an internal space; a shaft included in the internal space; a vibrating part suspended in the internal space by elastic members at both ends thereof, including a magnetic field part, and having a bearing member slidably and movably installed on the shaft; and a coil generating vibrations of the vibrating part through electromagnetic interaction with the magnetic field part and provided on an outer peripheral surface of the shaft while facing the magnetic field part.

A low cost gas turbine combustor has main nozzles having a cylindrical central tube using an interior as an oil fuel path, a cylindrical outer tube disposed on an outermost periphery of the main nozzle, and a support tube disposed between the central tube and the outer tube, the central tube, the outer tube and the support tube each being formed independently. The support tube has such an internal diameter as to form a clearance becoming an insulating air layer between the support tube and an outer periphery of the central tube, and includes supporting portions formed on an axially upstream side and radially contacting an inner periphery of the outer tube groove portions formed along an axial direction between the supporting portions, and a cylindrical portion formed on an axially downstream side and having an external diameter equal to or smaller than an external diameter of the groove portions.

A solenoid valve ( 30 ) is proposed here, the armature ( 28 , 27 ) of which is constructed in multiple parts, with an armature plate ( 28 ), an armature screw ( 27 ), which is guided in a slide ( 34 ). In order to avoid excessive vibrations of the armature plate (28) after the solenoid valve (30) is closed, a vibration damper (50) is arranged on the magnet armature (25). With this device, the instantaneous switching time required by the solenoid valve can be precisely maintained. This solenoid valve (30) is intended for fuel injection equipment with Common Rail.

A structure for the front portion of a vehicle is provided with a bumper face which is provided at the front end of the vehicle and a lower grille which is disposed at a bumper opening in the bumper face. The bumper face is provided with: a hook cover (20) which is formed integrally within the bumper opening with the bumper face and then separated from the bumper face; and a hook cover holding mechanism (26) which is formed integrally within the bumper opening with the bumper face and which supports and affixes in a removable manner the hook cover (20). The hook cover (20) has: a cover body (40) which closes a hook cover mounting section provided to the bumper face; and a cover engagement claw (32) which is engaged with a bumper engagement section provided to the hook cover mounting section. The hook cover holding mechanism (26) has a holding engagement claw (34) with which the cover engagement claw (32) is engaged in a supported manner when the hook cover (20) is elastically deformed.

A ventilation valve for a vehicle for letting air out of a vehicle interior includes a valve frame with at least one through opening, and at least one valve flap which is mounted on the valve frame and is adjustable between a closed position and an open position. The at least one valve flap closes the at least one through opening in the closed position and opens up the at least one through openingin the open position. Air escaping through the at least one through opening flows from an air inlet side to an air outlet side along a main flow direction. A wall bounding the at least one through opening is inclined into the air flow in such a manner that the through opening tapers in the main flow direction.

Feeder channel (1) for diluting fluid, such as for diluting water, which feeder channel is in connection with the headbox (10) of a paper machine and comprises one or more reservoir-type spaces (7), such as a chamber, for receiving diluting fluid, which space comprises one or more walls (4), and that an aperture (13) is formed in the reservoir-type space (7), via which aperture the diluting fluid can be conducted into the stock flow space (9) of the headbox, and that one or more shut-off / adjustment means (5), with which the flow of diluting fluid via the aforementioned aperture (13) can be adjusted, is fitted into the feeder channel (1), and that the shutoff / adjustment means (5) is a shut-off / adjustment means that can be moved in the longitudinal direction of an aperture that is in connection with the aperture (13) formed in the wall (4) of the reservoir-type space, and that in the shutoff / adjustment means (5) that is partly or wholly inside the aperture there are one or more cavities and / or recesses (6, 14), via which the flow of diluting fluid from the reservoir-type space (7) either directly or via an intermediate piece (11) into the stock flow space (9) can be adjusted by moving the shut-off / adjustment means (5) in the aperture (13), and that the shut-off / adjustment means (5) comprises a support surface or support surfaces (6''), which can rest on the inside surface (13') of the aperture (13) for preventing vibration of the adjustment means (5) caused by the flow of the diluting fluid at least during operation of the shut-off / adjustment means.

A hollow cylinder of a drum is equipped with a lug fixing structure for detachably attaching a lug thereto by using a lug fixing member, which projects externally from the hollow cylinder and engages with an engagement hole of the lug. Herein, the lug fixing member has a spacer by which the lug is spaced apart from the exterior circumferential surface of the hollow cylinder and would not come in direct contact with the hollow cylinder. Thus, it is possible not to prevent the hollow cylinder from vibrating during playing of a drum. In addition, the lug is turned over after released from the lug fixing member, which is thus prevented from being engaged with the engagement hole of the lug again. This guarantees rapid replacement of a drumhead because a human operator can easily release engagement between the lug and lug fixing member without performing troublesome operation.
