Abstract: A method of manufacturing a rectangular battery includes: ironing the blank thereby forming an interim cup including an interim bottom whose area is larger than a bottom plate of the rectangular battery can, an inclined wall tilting upwardly formed continuously from each longitudinal end of the interim bottom, a short side wall formed continuously from the inclined wall, and a long side wall formed continuously from a curved corner formed on each lateral end of the interim bottom; deforming the interim cup such that each boundary between the interim bottom and the inclined wall is displaced toward a longitudinal end of the bottom plate of the rectangular battery can, and a width of the interim bottom is adjusted to a width of the bottom plate of the rectangular battery can; and ironing the short side and long side walls to reduce thicknesses of the short side and long side walls.

Abstract: A manufacturing method of a battery case having a rectangular transverse cross-section in which an intermediate product having an elliptical transverse cross-section is shaped into a final product having a rectangular transverse cross-section by drawing and ironing the intermediate product multiple times to reduce a curvature radius of each corner and thicknesses of side walls formed on both sides of the corner. A difference between an ironing rate of the side wall formed on one side of the corner and an ironing rate of the side wall formed on the other side of the corner is reduced less than a predetermined difference, after the curvature radius of the corner between the side walls has been reduced shorter than a predetermined radius during the process of shaping the intermediate product into the final product.

Abstract: A vehicle is equipped with a slide door, a seat provided near an ingress-egress opening, and an ingress-action detector to detect a passenger's ingress action through the ingress-egress opening. The vehicle is further equipped with an illumination device which comprises lower illuminators which are configured to illuminate lower areas which are located below a beltline of the vehicle such that a passenger's upper body is not illuminated, vehicle-inside upper illuminators which are configured to illuminate an upper-specified area in the vehicle compartment which is located above the beltline, and an illumination controller to control the illuminators. When the ingress action is detected by the ingress-action detector, the illumination controller prohibits the illuminations of the illuminators and starts the illuminations of the illuminators.

Abstract: It is intended to provide a method for improving a development rate in a somatic nuclear transplantation technique or an artificial insemination technique using a spermatid. The method is a method for producing a nuclear-transplanted egg comprising the steps of transplanting a nucleus of a donor cell into an egg, and treating the nuclear-transplanted egg with an anti-methylating agent.

Abstract: To provide meat that is beneficial to human health, for the purpose to produce transgenic animals in which the content of unsaturated fatty acids increase is increased, transgenic animals characterized by increased content of unsaturated fatty acids that are beneficial to human health is provided by the present invention. Furthermore, the present invention also provides a method to enhance levels of unsaturated fatty acid in animals.
