Abstract: A formed material 1 having a cylindrical trunk portion 10 and a flange portion 11 formed at an end section of the trunk portion is manufactured by performing multi-stage drawing of a material metal sheet. Multi-stage drawing includes: preliminary drawing that forms, from a material metal sheet 2, a preform 20 having a trunk element 20a; compression drawing that is performed at least once after the preliminary drawing and that forms the trunk portion 10 by drawing the trunk element 20a while applying a pressure-adjustable compressive force to the trunk element 20a; and finish-ironing that is performed for securing dimensional precision at least once following the compression drawing.

Abstract: A formed material having a tubular body and a flange formed at an end of the body is manufactured by multistage drawing of a blank metal sheet. The multistage drawing includes preliminary drawing in which a preliminary body having a body preform is formed from the blank metal sheet, and at least one compression drawing which is performed after the preliminary drawing and in which the body is formed by drawing the body preform while applying a compressive force to the body preform. The at least one compression drawing is performed so as to be completed before the pad portion of pressurization means reaches bottom dead center, and a support force supporting the pad portion acts as the compressive force upon the body preform when the body preform is drawn.

Abstract: An ironing mold according to the present invention is provided with a punch, and a die which forms a pushing hole with respect to the punch. When the skewness Rsk of a surface treated metal plate is less than ?0.6 and no less than ?1.3, then the curvature radius of a shoulder portion of the die and a clearance between a radius end and the punch are determined such that Y, which is expressed by {(tre?cre)/tre}×100, and X, which is expressed by r/tre, satisfy 0<Y?18.7X?6.1, X satisfies X?0.6 and r satisfies r?0.5 h.

Abstract: A formed material is manufactured by performing forming including at least one drawing-out process and at least one drawing process performed after the drawing-out process. A punch 31 used in the drawing-out process is formed to be wider on a rear end side than on a tip end side. By pushing a raw material metal plate into a pushing hole 30a together with the punch 31, ironing is performed on a region of the raw material metal plate corresponding to a flange portion.

Abstract: The invention provides a formed material manufacturing method by which unnecessary thickening of a flange can be avoided. The formed material manufacturing method allows a formed material to be manufactured by forming processes that include at least one drawing-out process, at least one drawing process performed after the drawing-out process, and at least one coining process performed after the drawing process. The width of the rear end side of a punch used in the drawing-out process is set to be wider than the width of the tip end side thereof. An ironing process is performed on a region corresponding to the flange of the base metal sheet by pushing the base metal sheet together with the punch into a pushing hole.

Abstract: There is provided a portable terminal including a display panel having a display surface with a touch pad, an area management unit which defines a plurality of display areas formed by dividing the display surface, and a display control unit which performs control on an image display in each display area. In a state where two display areas are defined with a first boundary line, in response to a touch operation on the touch pad, the area management unit determines, based on a touch position of the touch operation, a second boundary line passing one point on the first boundary line and one point within a predetermined range from the touch position and defines two areas which are formed by dividing an object area of the two display areas with the second boundary line, as first and second display areas in place of the object area.

Abstract: An ironing mold according to the present invention includes a punch that is inserted into a formed portion, and a die having a pushing hole into which the formed portion is pushed together with the punch. An inner peripheral surface extends non-parallel to an outer peripheral surface of the punch, and the inner peripheral surface is provided with a clearance that corresponds to an uneven plate thickness distribution, in the pushing direction, of the formed portion prior to the ironing relative to the outer peripheral surface to ensure that an amount of ironing applied to the formed portion remains constant in the pushing direction.

Abstract: An open magnetic circuit coil (6) is arranged on a line connecting a battery (1) to a charger (CH1). Furthermore, a resistor (2) is connected in series with a large-capacitance electrolytic capacitor (7) for smoothing a charger output which is connected to the output of the charger (CH1). This can suppress an abrupt change in current flowing in the connection line between the battery (1) and the charger (CH1) in connection between plugs (3a, 3b).
