A sealing structure for a battery includes a plate shaped member having a through hole, a polymer molding, and an electrode. The polymer molding has a tube portion provided along an entire edge of the through hole and a base portion provided on the tube portion. The electrode has a column portion disposed on an inner periphery of the tube portion and a plate portion provided on the column portion. A back surface of the plate shaped member contacts a front surface of the base portion. A front surface of the plate portion contacts a back surface of the base portion. The back surface of the plate shaped member has an annular first projection provided around the through hole and projecting toward the base portion. The front surface of the plate portion has an annular second projection provided around the through hole and projecting toward the base portion.

The invention provides novel pellets having high fluidity in a hopper of an extruder and capable of forming a coating layer having good wire diameter stability and capacitance stability even when used for rapid molding of electric wire coating. The pellets contain a fluororesin. Each of the pellets, placed on a horizontal surface, has a substantially circular outline or a substantially elliptic outline and has a major axis Dof 3.1 mm or shorter and a minor axis Dof 3.1 mm or shorter when observed in the direction normal to the horizontal surface. Each pellet satisfies the following formula (1): (D+D)/2L=1.8 to 2.6, wherein Drepresents the major axis, Drepresents the minor axis, and L represents the height from the horizontal surface to the highest point of the pellet.

A thermoplastic resin pellet is columnar. A cross-sectional shape taken along a plane orthogonal to a height direction of the thermoplastic resin pellet has a longer diameter represented by 'a' and a shorter diameter represented by 'b'. A ratio a/b is greater than or equal to 1.0, and the ratio a/b is less than or equal to 2.6. A ratio &#x3b1; of a unit height volume of a cylindrical portion of a hopper of a molding machine, into which the thermoplastic resin pellet is loaded, to a volume of the thermoplastic resin pellet is greater than 16. A method for manufacturing an electric cable includes supplying the thermoplastic resin pellet to the hopper, melting the thermoplastic resin pellet in the cylinder to supply molten resin to the die, and extruding the molten resin from the die to form a sheath on a core wire.

A joint is connected to a tube and includes a joint body, nut, and ring. The joint body has a tube coupling part and a main body thread part. The nut has a nut thread part and a constricted diameter part. The ring is arranged in a space radially inward of the nut thread part. The ring abuts an abutted part of the nut. The ring has a Young's modulus greater than the tube. The ring has a curved surface part at least at a radially inward portion of the ring axially on the joint body side, the curved surface part bulging radially inward of the ring and axially toward the joint body side. A maximum thickness of the ring in a radial direction is defined as 2r, an axial length of the curved surface part of the ring is defined as h, and &#x3b1;=h/r being 0.5 to 1.2.

Joint and joint assembly

In an air conditioner for installation at a high location, a plurality of parallel reinforcement ribsare formed on a top platethat forms a top surface of a body casing and supports and holds a fan and a fan motor. When the top platehas the same plate thickness as a top plate of the prior art including radial reinforcement ribs, the top platehas a smaller maximum deflection and a higher resonance rotation speed than the prior art top plate.
