    摘要： A method of producing a magnetic recording medium comprises the steps of kneading and dispersing ferromagnetic powder, binder and non-ferromagnetic powder to obtain magnetic coating solutions, and applying a plurality of the magnetic coating solutions on a non-ferromagnetic substrate to form a plurality of magnetic layers on the substrate. In the kneading and dispersing step, a magnetic coating composition containing a ferromagnetic powder and a solvent of 15 to 30 wt % of the ferromagnetic powder is kneaded by a two-shaft continuous kneading and mixing machine and then dispersed by a pin type sand grinder to obtain a first magnetic solution. Another magnetic coating composition containing a ferromagnetic powder and a solvent of 30 to 50 wt % of the ferromagnetic powder is kneaded by a double-arm open kneader and then dispersed by a pin type sand grinder, and finally dispersed by a disk type sand grinder to obtain a second magnetic coating solution. In the magnetic solution applying step, the first magnetic coating solution is at first applied on said substrate and then the second magnetic coating solution is applied thereon.

    摘要： The invention provides a method for evaluating the safety of a battery under an internal short-circuit condition. The battery includes: an electrode group including a positive electrode, a negative electrode, and an insulating layer for electrically insulating the electrodes, which are wound or laminated; an electrolyte; a housing for housing the electrode group and the electrolyte; and a current-collecting terminal for electrically connecting the electrode group and the housing. The method of the invention includes: placing a foreign object at a location inside the electrode group of the battery where the positive electrode and the negative electrode face each other; and pressing the location by the pressure applied by a pressing tool to locally crush the insulating layer between the positive and negative electrodes, thereby causing an internal short-circuit. The contact area of the electrode group and the pressing tool during the pressing is larger than the area of a rectangle circumscribed about the foreign object. A short-circuit test is conducted at a given location inside the battery to comprehensively evaluate the safety of the battery under an internal short-circuit condition.
