摘要:
Elongated hollow members or tubes frictionally engage the interior wall of a hollow corrugating roll or a hollow pressure roll of a single facer so as to minimize the elastic vibration thereof and thereby to minimize the noise developed and transmitted during the operation of the single facer. A plurality of such tubes of a given diameter are arranged circumferentially about the interior wall of the shell of a roll of a single facer in such manner that each of the tubes frictionally engages the interior wall and so that each of the tubes also engages the adjacent tubes on either side thereof, thereby providing an assembled structure in which the plurality of tubes resist the elastic deformation of the roll and the resultant elastic vibratiion and thereby reduce the noise level. In a modified form of the invention, a second plurality of tubes of smaller diameter are arranged in similar fashion along a concentric circle radially inward of the first plurality of tubes, each of the second group of tubes being positioned in contact with two adjacent ones of the first group of tubes. A single centrally disposed tube may be positioned for further assisting in holding the assembled tubes in position. In other modified forms of the invention tubes of different diameters and wall thicknesses may be randomly arranged within the roll rather than being positioned in concentric circles of tubes of progressively decreasing diameter from the interior wall to the radially inmost position. In a further modification, annular members fixed to the interior wall of the roll may be provided at the ends of the tubes for further assisting in holding the tubes in position. Sound-deadening materials in solid or liquid form may be provided in some or all of the tubes or in the spaces between adjacent tubes.

The interior wall of a hollow corrugating roll or a hollow pressure roll of a single facer is frictionally engaged by a resilient member so as to minimize the elastic vibration thereof and thereby to minimize the noise developed and transmitted during operation of the single facer. The resilient member is positioned within the hollow interior of the roll and is arranged to press against the interior wall as a result of its resilience and thereby to reduce the elastic vibration of the roll and the noise transmitted. The resilient member may take various forms, such as a coiled helical spring, a coiled leaf spring, a plurality of tapered nested annular members engaging the interior wall of the roll, et cetera.
摘要:
Under a specified condition where a torque converter is kept in a lockup state to prolong the fuel-cutoff time, because of vehicle coasting with an accelerator opening APO=0, a downshift command is generated and then an automatic transmission causes a reengagement downshift by a drop in a release-side clutch hydraulic pressure Poff and a rise in an engagement-side clutch hydraulic pressure Pon. During the reengagement downshift, the engagement-side clutch hydraulic pressure Pon is reduced from a high lockup-ON hydraulic pressure to a low lockup-OFF hydraulic pressure after the time when the lockup is predicted to be released, thus preventing a torque drawing-in tendency of transmission output torque, which may occur at the time of the beginning of the inertia phase, from increasing, and also reducing in the width of a subsequent change in vehicle deceleration G, and consequently enhancing the shift quality.

A lock-up control system including a lock-up differential pressure generator and a controller that is programmed to: when increasing a lock-up differential pressure command value with time to establish the lock-up state of the torque converter, switch a gradient of the lock-up differential pressure command value from a first gradient to a predetermined gradient larger than the first gradient when an actual slip rotation speed is decreased to a predetermined slip rotation speed value or less; and switch the gradient of the lock-up differential pressure command value from the predetermined gradient to a second gradient smaller than the predetermined gradient when the actual slip rotation speed exceeds the predetermined slip rotation speed value again after being decreased to the predetermined slip rotation speed value or less.

A shift shock reducing apparatus for a power train having an engine and an automatic transmission having a frictional element that is to be engaged at upshift, comprising a control section that executes, during upshift, a torque down of the engine that starts before the start of an inertia phase in which a gear ratio of the transmission is changing from a before-shift gear ratio to an after-shift gear ratio, and a control section that makes larger a rising gradient of working oil pressure that is supplied to the frictional element to be engaged at upshift when the torque down that starts before the start of the inertia phase is executed than that when the torque down is not executed.

A self-traveling cleaning robot includes: a stepped portion detecting unit for detecting a stepped portion of a floor arranged on the center front part of the bottom of the robot main body; an angle detecting unit for detecting the rotation angle of the main body in horizontal direction of the main body; and a travel control unit for controlling a travel based on the detection output of the stepped portion detecting unit and the angle detecting unit, wherein the travel control unit stops when a stepped portion is detected by the stepped portion detecting unit, and rotates to the left and to the right in that state thus detecting the rotation angle up to the boundary of the stepped portion in each direction by way of the angle detecting unit, thereby correcting the posture of the robot main body based on the detected angle.
摘要:
When detecting suction of a lighted object such as a cigarette or a match, a self-propelling cleaner 1 sends it to a dust room 12a by controlling a valve 8a. The self-propelling cleaner 1 collects ordinary dust such as dust and wastepaper into a dust room 12b by controlling the valve 8a. Since a lighted object such as a cigarette and ordinary dust are thus sent to two different dust rooms in a discriminated manner, even if a lighted object such as a cigarette is sucked other dust in the dust room can be prevented from catching fire from it, whereby the self-propelling cleaner is made safer from suction of a lighted object.
