Abstract: A learning device 1X mainly includes a first acquisition means 31X, a second acquisition means 32X, and a learning means 34X. The first acquisition means 31X acquires a partial waveform of electrocardiogram data regarding an electrocardiogram of a subject. The second acquisition means 32X acquires an attention interval, which is used as a basis for a diagnosis of a target disease, in a sequential waveform of the electrocardiogram data. The learning means 34X trains a model configured to diagnose the target disease, based on the partial waveform and the attention interval.

Abstract: A press forming method for producing a saddle type final product comprises a first process of producing an intermediate product having a processing adjustment section, by cold press working against an ultrahigh tensile strength steel plate, to deform the side wall portions and flange portions at both sides in the predetermined area, with the cross section of the top plate portion being maintained in a predetermined shape, and a second process of pressing at least the processing adjustment section, by cold press working against the intermediate product, with the cross section of the top plate portion being maintained in the predetermined shape. In at least one of the first process and second process, a processing target of the at least one process is bent in the direction opposite to the opening of the hat-shaped cross section, to produce the saddle type final product.

Abstract: An omnidirectional camera device is able to restrict a range in which images of objects are picked up. This omnidirectional camera device comprises a rotationally-symmetric convex mirror (24) fixedly attached to one end of a transparent tube assembly (20), an image pickup means (32) disposed on the other end of the tube assembly in an opposing relation to this convex mirror and a cover assembly (60) disposed on the tube assembly for restricting the range in which light becomes incident on the convex mirror. The cover assembly is mounted on one end side of the tube assembly. The cover assembly is a shielding cover assembly and includes a cover member (60B). The cover assembly is attached to the tube assembly so as to become freely rotatable. The direction and the range in which images of objects should be picked up may be adjusted by the attachment position of the cover assembly and a shielding angle &agr; of the cover assembly.

Abstract: An omnidirectional vision sensor, which consists of a rotationally symmetrical convex mirror and a camera arranged opposite to the mirror, with clear and high quality image without having any disturbance due to the internal reflection of the light raised on the inner surface of the cylinder. The rays of light which internally reflect inside the cylinder pass through the production line of the rotational axis of the convex mirror, and thus these rays are eliminated before they reach the inner surface of the transparent cylinder. A tapered object on the vertex of the convex mirror is used to completely eliminate inner reflected rays of light.
