A stationary core includes a holding hole that receives and holds a portion of the magnetic spring, which is located on a valve opening side. A solenoid device includes a magnetic yoke that extends in an axial direction and has an axial extent, which overlaps with an entire axial extent of the holding hole.
Pneumatic tire for motorcycle
A pneumatic tire for a motorcycle that secures durability while improving grip performance in turning. A pneumatic tire for a motorcycle including a belt containing a belt layer formed by coating a plurality of cords with rubber in a tire tread, wherein the tread is provided with cushion rubbers separated from each other in the tire widthwise direction in both sides of the tire equatorial plane by a separated region and located outward in the tire radial direction from the belt, and a base rubber having a modulus higher than those of the cushion rubbers located in the separated region or outward in the tire radial direction therefrom, and wn, a length of the separated region, and wb, a length of the base rubber in the cross section in the tire widthwise direction, satisfy the relation: wn≦wb..
Linepipe with cermet internal liner
A linepipe with cermet internal liner includes: a base pipe; a cermet layer comprising corundum and titanium; and an alloy layer comprising chromium, nickel and iron; wherein the cermet layer and the alloy layer are respectively provided on an internal wall of the base pipe from inside out along a radial direction thereof. From inside out, the cermet layer includes: anα-al2o3 ceramic layer, a transition layer combined by two phases ofα-al2o3 and metallic titanium, and a metallic titanium layer, wherein thicknesses of the three layers respectively account for ¼, ½ and ¼ thereof the cermet layer.
Ignition system
An ignition system for an internal combustion engine includes a discharge portion of the center electrode in which a part thereof is surrounded by a bottom portion and a tubular tip portion of the center dielectric, the part of the discharge portion and the tubular tip portion are projected into a combustion chamber of the internal combustion engine from a substantially annular tip portion of the ground electrode that opens to the combustion chamber at a distal end of the ground electrode, a diameter-changing portion formed by reducing a diameter of a part of the tubular tip portion in a radial direction gradually as approaching toward a tip thereof, and a thin-walled portion formed by reducing a thickness of the tip of the tubular tip portion.. .
Grinding type vertical grain polishing machine
A bran removing wire-mesh tube includes: bran removing wire-mesh tube parts 28 divided in more than one in a circumferential direction in planar view; and a plurality of support pillars 33 erected at intervals in the circumferential direction to respectively fix both side edges of the divided bran removing wire-mesh tube parts 28. Each of the support pillars 33 is provided with an elongated resistor 34 that suppresses grains from moving in the circumferential direction along with rotation of grinding type grain cleaning rolls 26.
Torque detector and steering system including the torque detector
A torque detector includes: a magnetic flux collecting unit including a magnetic flux collecting holder formed in an annular shape by resin molding and a magnetic shield formed by bending a metal plate and attached to an outer peripheral face of the magnetic flux collecting holder; and a sensor housing formed integrally with the magnetic flux collecting unit. The magnetic shield has a shield body, a shield end portion, and a bent portion.
Enhanced device for determining the location of induced stress in stuck borehole tubulars
A method for identifying the location of a binding zone between a stuck tubular and a borehole includes the steps of passing a demagnetizing stress sensor through the tubular on a baseline magnetization pass to magnetize the tubular. Next, the demagnetizing stress sensor measures a baseline magnetization of the tubular.
