A rotor that includes a rotor core assembly secured to a shaft. The rotor core assembly includes a magnet and an end cap secured to an end of the magnet. Each of the magnet and the end cap has a bore into which the shaft extends. The end cap forms an interference fit with the shaft. The magnet forms a clearance fit with the shaft and an adhesive is located in the clearance between the magnet and the shaft. Additionally, a method of manufacturing the rotor. The method includes inserting the shaft into the bore of the end cap. An adhesive is then introduced into the bore of the magnet and the shaft is inserted into the bore of the magnet so as to cause adhesive to be drawn into the clearance defined between the magnet and the shaft.

A method and apparatus which quickly clamps onto the copper strand bundle in the slot of a dynamoelectric machine and rips out the coil from the slot one axial position at a time. As the copper bundle is ripped from the slot the tooling moves along the slot from one end to the other.

A pruning hook includes an extension shank, a blade unit including a fixed blade mounted on the extension shank and a movable blade pivotally connected with the fixed blade, a driving cord to drive the movable blade, a slide movably mounted in the extension shank to drive the driving cord, a pull cord mounted in the extension shank to drive the slide, and a pulling member movable relative to the extension shank to drive the pull cord. Thus, the pulling member is pulled by a user's arm to drive the blade unit so that the blade unit is driven by a greater force applied by the user's arm and has a larger shearing force to perform a cutting action in an easier manner so as to cut a larger object easily and conveniently.

Provided is a tire in which a first land portion partitions a first main groove from a second main groove. A first lug groove and a first sipe are provided in the first land portion. One end of the first lug groove communicates with the first main groove. The first sipe includes one end communicating with the second main groove and another end communicating with another end of the first lug groove. The first sipe includes a steeply inclined portion extending from the another end of the first lug groove and having an angle with respect to a tire circumferential direction smaller than that of the first lug groove, and a gently inclined portion extending from the steeply inclined portion to the second main groove and having an angle with respect to the tire circumferential direction larger than that of the steeply inclined portion.

The invention is directed at a print head for printing a suspension fluid. The print head comprises a nozzle having one or more nozzle outlets for allowing the suspension fluid to be ejected from the nozzle, a flow path including a supply channel for supplying the suspension fluid to the one or more nozzle outlets, and a supply pump for establishing a flow within the flow path. The nozzle further comprises an actuator for imparting pressure fluctuations on the suspension fluid at the one or more nozzle outlets for generating a stream of droplets therefrom. The flow path further comprises a shear section for locally increasing the shear rate at least at a location in the flow path upstream of the one or more nozzle outlets. The flow path further includes a return channel for allowing excess fluid not ejected from the nozzle to flow away from the one or more nozzle outlets. The shear section is configured to locally increase the shear rate to be larger than a shear rate obtained near at least one of the one or more nozzle outlets. The invention is further directed at a printing apparatus, a method of printing, and a method of manufacturing a print head.

In a screw for extruder, a bearing segment having a function of supporting a screw main body at an intermediate part when kneading is performed is provided at a position corresponding to a kneading portion or on the downstream side of the kneading portion. The bearing segment is provided with at least two flights having a sectional shape of a complete meshing type with one streak in the axial direction, the flights are arranged in the rotational direction with uniformly displacing a phase thereof respectively, and length of the flights in the axial direction is set to 0.2D (D: rotational outer diameter of the bearing segment) or more. According to the above configuration, bending of the screw main body is prevented and abrasion of the flights and a barrel is suppressed.
