It has been confirmed that even though there is a difference in the dimension of a perpendicular reference surface of a permanent magnet, there is almost no change in surface magnetic flux density, and variations in the dimension of the perpendicular reference surface do not much affect the surface magnetic flux density. Therefore, even though variations occur in the dimension of the perpendicular reference surface, variations in the characteristics of an IPM motor are prevented.

It can be considered that a cross-sectional shape of a permanent magnet having a parallel reference surface is obtained by removing a portion from a cross-sectional shape of a permanent magnet which does not have the parallel reference. A cross-sectional area of the permanent magnet is further reduced than that of the permanent magnet which does not have the parallel reference surface. In addition, also a magnet volume of the permanent magnet is further reduced than that of the permanent magnet that does not have the parallel reference surface. The inventors have confirmed that a decrease in magnet volume induced by the parallel reference surface does not affect the characteristics of an IPM motor.

An R-T-B based sintered magnet includes RTB crystal grains. A grain boundary formed by the two or more adjacent RTB crystal grains includes an R&#x2014;N&#x2014;O&#x2014;C concentrated part having higher concentrations of 'R', N, O, and C than those in the RTB crystal grains. 'R' of the R&#x2014;N&#x2014;O&#x2014;C concentrated part includes Y. A ratio of Y atom to 'R' atom in the R&#x2014;N&#x2014;O&#x2014;C concentrated part is 0.65 or more and 1.00 or less. A ratio of O atom to &#x201c;R&#x201d; atom in the R&#x2014;N&#x2014;O&#x2014;C concentrated part is more than 0 and 0.20 or less. A ratio of N atom to &#x201c;R&#x201d; atom in the R&#x2014;N&#x2014;O&#x2014;C concentrated part is 0.03 or more and 0.15 or less.

R-T-B based sintered magnet

An R-T-B based sintered magnet including a main phase composed of an RTB (wherein, R is at least one selected from the group consisting of Y, Ce, La, Pr, Nd, Sm, Eu and Gd; and T is one or more transition metal elements with Fe as necessity) structure, wherein the R-T-B based sintered magnet has a grain boundary phase containing Ce, Fe and Co, and the cross-section area ratio of the grain boundary phase containing Ce, Fe and Co in a unit cross-section area is 1.0% or more and 5.0% or less.

A bayonet connection structure between a container mouth portion and a cap is disclosed. The cap includes multiple slip prevention claws spaced apart from each other. One of the slip prevention claws is elastically displaceable in a radial direction. A rotation prevention projection is provided between the elastically-displaceable slip prevention claw and the other slip prevention claws. The mouth portion has a hollow cylindrical portion with an outer circumferential surface provided with multiple slip prevention claw (SPC) engagement portions for the slip prevention claws. The SPC engagement portions are as many as the slip prevention claws. Each of the SPC engagement portions has an end in a clockwise direction provided with a rotation prevention stopper. The mouth portion includes a rotation prevention rib to be got over by the rotation prevention projection of the cap when the cap is rotated.

A cover is laterally mounted on an inner assembly which is a unit including all structural elements except for the cover. The cover is fixed to the inner assembly at three portions. A fitting projection provided on the upper surface of a nozzle base is received in a fitting hole formed in the upper surface of the ceiling of the cover. A pair of opposed engaging pieces are formed on the lower surface of a cylinder and the upper surface of a valve assembly, respectively. An engaging piece engaging with a space between the opposed engaging pieces is formed on the lower end of the cover. A horizontal engaging groove is formed in the upper surface of the nozzle base behind the fitting projection on the nozzle base and a projection engageable with the engaging groove is formed on the inner surface of the ceiling of the cover.

Pump dispenser and a method of assembling the pump dispenser

A dispenser body comprises an upper portion and a lower portion vertically extending from the upper portion. A piston is substantially L-shaped, comprising a horizontal nozzle fixed to the upper body portion and a piston body located at the lower body portion. A cylinder is coupled with a swingable trigger and located at the lower body portion; it can reciprocate when the trigger is squeezed and released. An inlet conduit is formed within the cylinder, whereas an outlet conduit is provided within the piston. A slit is cut in the front section of the lower body portion. Thanks to this slit, the lower body portion is resiliently fitted in a bottle cap and, thus, connected thereto. The rear end of the trigger and the nozzle can pass through this slit. The piston is engaged with the cylinder, and supports the cylinder in its lower position, i.e., the non-operation position of the cylinder.

A check valve comprises a valve body and a plurality of blades--all made of plastics and integral with one another. The blades extend straight in the axial direction of the valve body. The blades undergo elastic deformation when pushed onto a tapered inner surface of a stopper at their free ends, thereby biasing the valve body onto a valve seat.

A dispenser body molded of plastic material includes an upper body portion on which a trigger is swingably pivoted and a vertically extending lower tubular portion. A piston has an L shape and includes an upper folded horizontal portion carried by spaced vertical wall portions of the upper body portion. The piston is vertically disposed in the upper body portion. A nozzle member is mounted on the terminal end of the upper folded horizontal portion. An outlet conduit, communicating with an orifice formed in the nozzle member, is formed in the piston. A cylinder coupled to the trigger is disposed to slide vertically along the piston within the lower tubular portion. The cylinder defines a pump chamber communicating with the outlet conduit. An inlet conduit communicating with the pump chamber is formed in the cylinder. A compression spring, seated in the cylinder at the lower end thereof and abutting on the lower end of the piston at upper end thereof, biases the cylinder to its lower non-operation position.
