A low rigidity region being more stretchable and bendable than a high rigidity region, includes a main portion, and a medial first flexible portion and a lateral first flexible portion extending from the main portion in the medial and lateral directions. The main portion covers a portion of the area from the shaft of the first proximal phalanx to the shaft of the second proximal phalanx, the medial first flexible portion covers a portion of the area from the shaft of the first proximal phalanx to the head of the first metatarsal bone, and the lateral first flexible portion extends to the lateral side of the foot from the main portion. When pushing off the foot onto the medial/lateral side in a diagonally forward direction, the upper bends along the diagonal bend lines. Therefore, the diagonal portions and the main portion serve as the bend lines.

A shoe having a sole, an upper including a first opening and a second opening, and shoelace means, the upper including: a first side edge portion having a plurality of first eyelets; a second side edge portion arranged between the plurality of first eyelets and having one or more second eyelets which the shoelace means engages with; a movable portion for allowing the second eyelet to move with respect to the first eyelets both in a transverse direction across the second opening and a diagonal front-back direction that is perpendicular to the transverse direction and is extending along the instep; and a main portion covering a medial side surface, a lateral side surface, a toe, the instep and a back surface of a foot, the main portion including the first side edge portion and excluding the second side edge portion and the movable portion; the second eyelet is relatively displaced via the movable portion with respect to the main portion both in the transverse direction and the diagonal front-back direction in response to a change in a direction of a resultant force between a first tensile force and a second tensile force acting upon the second side edge portion from a V-shaped portion of the shoelace means engaging with the second eyelet while transitioning from a flat-footed position to a heel-raised position.

An athletic shoe suitable for efficient running. A depression is formed in the rear foot portion which extends forward from the calcaneal bone and which does not contact the ground. A band-like area is provided in the middle foot portion extending in the front-rear direction in the central portion between the medial side and the lateral side of the shoe sole so as to be continuous with the depression. The reinforcement member and the midsole are provided in the middle foot portion so that the upper surface of the midsole less easily sinks downward due to a load from above on the medial side than in the band-like area and on the lateral side. In the front foot portion, a longitudinal groove is formed which extends in the front-rear direction in the central portion of the midsole body so as to be continuous with the band-like area. The longitudinal groove is curved so as to be generally parallel to the lateral edge of the front foot portion of sole.

Three or more holes are formed in a lower portion of a first area D1 in a midsole body 29 separated from one another in a front-rear direction Y, each hole opened in a downward direction and having an inner peripheral surface about an axial line extending in an up-down direction; embedded portions each have an outer peripheral surface about the axial line, and are embedded in the midsole body 29 while being fitted into the holes; the embedded portions are formed by a hard member 4 made of a resin harder than midsole bodies 20 and 29 and outsoles 5 and 5A; and the hard member 4 includes a connecting portion for connecting together the embedded portions in the front-rear direction Y on the lower surface of the midsole body 29.

IGBT 10 comprises an n+-type emitter region, an n−-type drift region, a p-type body region disposed between the emitter region and the drift region, a trench gate extending in the body region from the emitter region toward the drift region, and a projecting portion of an insulating material being in contact with a surface of the trench gate. At least a part of the projecting portion projects within the drift region.

The present invention relates to the upper U of an athletic shoe comprising a first opening 1 out of which the foot sticks upwards during wearing and a second opening 2 which is closed with a tongue. The two openings 1, 2 are continuous with each other, and the upper U comprises a medial side stretchable part 51 which covers a part of a medial side face of an arch of the foot, a lateral side stretchable part 50 which covers a part of a lateral side face of a ball of a little toe (a fifth toe), a front part 3 located forward of the two stretchable parts 50, 51 and a rear part 4 located backward of the two stretchable parts. Each of the stretchable parts 50, 51 is provided so as to essentially cross one of side faces of the upper U from a top surface of a sole S to the second opening 2. Young's modulus along the lengthwise direction L of the foot of each of the stretchable parts 50, 51 is set smaller than that of the front part 3 and the rear part 4.

There is provided a structure of a sole which may suppress excessive bending, thereby improving the running efficiency, by reinforcing the front foot portion of a sole having a reduced weight. The disclosure is directed to a shoe sole, including a mid sole 2 for absorbing an impact of landing, an outer sole 1 placed under the mid sole 2 so as to be in contact with ground, and a reinforcement element 3 for suppressing bending of a front foot portion Ff during push-off. The reinforcement element 3 is an integral resin part formed in a loop shape, the reinforcement element 3 including a medial reinforcement portion 34 extending in a front-rear direction L along a medial side IN of the front foot portion Ff; a lateral reinforcement portion 35 extending in the front-rear direction along a lateral side of the front foot portion; a connection and reinforcement portion 37 for connecting together the medial and lateral reinforcement portions 34 and 35 and also for providing reinforcement; and a connection portion 38 for connecting together the medial reinforcement portion 34 and the lateral reinforcement portion 35 in an area posterior to the connection and reinforcement portion 37.

The present invention presents a stencil mask in which various surface patterns can be formed, and in which deformation is suppressed when charged particles are introduced. A stencil mask of the present invention is provided with a semiconductor stack. A first penetrating hole corresponding to an ion introducing area is formed in a first semiconductor layer of the semiconductor stack, and second penetrating holes are formed in a second semiconductor layer, these second penetrating holes having a width greater than the width of the first penetrating hole. The first penetrating hole and the second penetrating holes communicate and pass through the semiconductor stack. Beam members extending between adjacent second penetrating holes connect portions of the first semiconductor layer separated by the first penetrating hole.
