摘要： 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 α 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.

摘要： 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 D1 of 3.1 mm or shorter and a minor axis D2 of 3.1 mm or shorter when observed in the direction normal to the horizontal surface. Each pellet satisfies the following formula (1): (D1+D2)/2L=1.8 to 2.6, wherein D1 represents the major axis, D2 represents the minor axis, and L represents the height from the horizontal surface to the highest point of the pellet.

摘要： A sealing member is one used for a cylindrical lithium-ion battery. The sealing member is interposed between a bottom-closed cylindrical case and a cap, is made of perfluoropolymer, and has dimensions that meet the following relational expressions: when an axial distance from a cap upper surface to a leading end portion in a case is defined as HC, an axial distance from the cap upper surface to a leading end portion in the sealing member is defined as HG, a thickness of the sealing member is defined as TG, a value of TG divided by HG is defined as X (=TG/HG), and a value of HG divided by HC is defined as Y (=HG/HC),
X>0.800TG−0.324 (1)
Y 0.594X2−1.176X+0.913 (3).-

摘要： 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.

摘要： 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 α=h/r being 0.5 to 1.2.
