Abstract: A virtual image display device includes: a switching mechanism for switching a position of a view angle including a first position and a second position; and a display control unit for displaying the virtual image in response to a switching of the position of the view angle by the switching mechanism. When the display control unit displays a specific content within the view angle at the second position after the switching mechanism switches the view angle from the first position to the second position, the display control unit starts displaying a related content preliminarily associated with the specific content before the switching of the view angle to the second position is completed.

Abstract: A welding step involves solid-state welding together an external terminal and a seat portion of an internal terminal by causing the external terminal or the internal terminal to vibrate while detaching an insulator from the external terminal in at least a region surrounding the seat portion and pressing the external terminal against the seat portion.

Abstract: A battery manufacturing method includes assembling an internal terminal, a gasket, a battery case component, an insulator, and an external terminal into a state where a cylindrical part of the gasket is fitted in a mounting hole of the battery case component, a projecting part of the internal terminal is fitted in the cylindrical part of the gasket, the insulator is disposed on an outer surface of the battery case component with the projecting part fitted in a through-hole, and the external terminal is disposed on top of the insulator so as to lie on the projecting part. The external terminal is pressed against the projecting part of the internal terminal, and the external terminal or the internal terminal is vibrated to thereby weld together the projecting part and the external terminal in a solid state.

Abstract: A calibration area has a rectangular area and a peripheral area. The rectangular area includes a center area provided in the center portion and a first corner area, a second corner area, a third corner area, and a fourth corner area that are set at four corners sequentially in the circumferential direction. The center area has a line symmetry with respect to each of the two orthogonal axes passing through the center of the rectangular area. The heights of the areas are different.

Abstract: A sealed-type battery includes an exterior body, a collector terminal, a hollow rivet defining a hollow section, and a reverse plate arranged between the collector terminal and the hollow rivet. The collector terminal includes: a projected section projected; a peripheral edge section provided; and a notch section provided in the peripheral edge section in a manner to surround the projected section and formed in a manner to reduce thickness of the collector terminal. In a projected direction of the projected section, the projected section is thicker than the peripheral edge section. A fitting section, to which the projected section is fitted, is provided in the reverse plate. The sealed-type battery includes a welded section that has a top surface opposing the hollow rivet and that joins the collector terminal and the reverse plate at a position between the projected section and the fitting section.

Abstract: A battery houses an electrode body inside a battery case including a bottomed cylindrical case body having an opening part, and a plate-like lid member inserted in the opening part so as to seal the opening. The opening part and a lid peripheral edge part are welded hermetically by an energy beam irradiated from outside in the thickness direction of the lid member. In a specific section, the inner peripheral surface of the opening part and the peripheral edge surface of the lid peripheral edge part are welded in close contact with each other. A bead at the specific section takes a fan shape having a central angle of 160 to 200 degrees in a cross section, and the center of the fan shape is positioned on the inner peripheral surface and the peripheral edge surface.
