Abstract: A continuously variable transmission includes: a first pulley and a second pulley each including a fixed pulley and a movable pulley; and an endless member wound around the first pulley and the second pulley, wherein the continuously variable transmission continuously changes a speed ratio by controlling a thrust of the movable pulley with a hydraulic pressure, the thrust of the movable pulley is made smaller as a rotation speed of the first pulley decreases, and when the rotation speed of the first pulley is lower than a predetermined rotation speed, the thrust of the movable pulley in a case where the speed ratio is on a Low side of the predetermined speed ratio is not made smaller than the thrust of the movable pulley in a case where the speed ratio is on a High side of the predetermined speed ratio.

Abstract: A positive electrode active material with high charge and discharge capacity is provided. A novel positive electrode active material is provided. The positive electrode active material is manufactured in such a manner that after a cobalt compound (also referred to as a precursor) containing nickel, cobalt, and manganese is obtained by a coprecipitation method, a mixture obtained by mixing a lithium compound and the cobalt compound is heated at a first temperature; after the mixture is ground or crushed, heating at a second temperature that is a temperature higher than the first temperature is further performed; and after an additive is mixed, third heat treatment is performed. The first temperature is higher than or equal to 400° C. and lower than or equal to 700° C. The second temperature is higher than 700° C. and lower than or equal to 1050° C.

Abstract: A method for manufacturing a cylindrical honeycomb fired body including: preparing a cylindrical honeycomb formed body; obtaining a cylindrical honeycomb dried body by drying the cylindrical honeycomb formed body; calculating predetermined parameters (EAVE1, EAVE2, EAVE3 and EAVE4) from average values of distance between a center of gravity position O and an outer peripheral contour in a plurality of predetermined angle ranges; specifying a minimum value of the predetermined parameters; obtaining a cylindrical honeycomb fired body by placing the cylindrical honeycomb dried body on a shelf plate and firing it while passing it through a continuous firing furnace, such that the direction in which the cells of the cylindrical honeycomb dried body extend vertically, and a particular location on the outer peripheral side surface determined according to the minimum value is positioned at the front.

Abstract: A bearer for bearing a honeycomb green body includes a solid main body provided with a groove in which a concave arc surface extends along one direction; and a single-layer or multi-layer sponge layer attached to the arc surface of the groove. The sponge layer is curved along the arc surface of the groove and has a bearing surface curved along the arc surface.

Abstract: A method for manufacturing a pillar-shaped honeycomb fired body including: measuring a firing shrinkage at an end surface of a first pillar-shaped honeycomb firing body at every predetermined angle for one round based on a portion that has been located at the center of a die when a green body passes through the die, obtaining a second pillar-shaped honeycomb formed body having a corrected end surface contour by modifying an annular mask used for extrusion molding based on a result of the measuring, and then obtaining a second pillar-shaped honeycomb fired body by performing drying and firing.
