Abstract: A press-forming apparatus includes a punch, a die having an inclined surface, and a die holding plate. A blank holder has a holding surface, and a die load sensor detects a load in a pressing direction, a load in a first direction perpendicular to the pressing direction, and a load in a second direction perpendicular to the first direction. A controller calculates a normal force of the die based on the loads in the pressing direction, in the first direction, and in the second direction. The loads are detected by the die load sensor, and the controller calculates the amount of correction of clearance between the die and the blank holder based on the normal force of the die. The first driver moves the die in the pressing direction based on the amount of correction of clearance, and a second driver drives the punch in the pressing direction.

Abstract: A motor includes a rotor and a stator. The stator is formed by laminating a plurality of magnetic thin strips each having a plurality of teeth parts. The magnetic thin strip includes an elliptical-shaped inner diameter part formed along tip end portions of the plural teeth parts. At least one magnetic thin strip in the laminated magnetic thin strips is shifted by a given angle with respect to other magnetic thin strips in a horizontal direction, and positions of all teeth parts of the laminated magnetic thin strips correspond to one another to reduce cogging torque.

Abstract: The purpose of the present invention is to provide a battery block that serves as a member that contains a plurality of battery cells, wherein if abnormal heat generation occurs, the resulting heat is evenly, rapidly, and efficiently distributed throughout the entire block, and the portions in which the battery cells are accommodated have high dimensional precision. The present invention provides a battery block that contains the following: a metal case that contains a plurality of pipe-shaped members; and battery cells accommodated, respectively, in said plurality of pipe-shaped members. The pipe-shaped members are joined to each other, forming a single unit, and join parts that join adjacent pipe-shaped members to each other are at least 70% as long as the pipe-shaped members themselves.
