摘要： PROBLEM TO BE SOLVED: To provide a rotor laminated core of a rotary electric machine with sufficient profile precision and its manufacturing method for realizing superior productivity in bricklaying lamination in which a separation end face of a separation rotor core strip is dislocated in the lamination direction. SOLUTION: Separation rotor core strips 21, 22, in which each annular rotor core strip is divided into a fan shape at desired angle, are laminated to form a separation rotor lamination core 13, and two or more separation rotor lamination cores 13 are joined in an annular way in the rotor laminated core 10 of the rotary electric machine. The separation rotor core strips 21, 22 are laminated by clamping by turn or turn-back at a predetermined angle for every one piece or two or more pieces in a hoop direction. The concave-convex parts 11, 12 formed in a hoop direction at an edge of the separation rotator lamination core 13 subjected to clamping lamination, are engaged with each other so that two or more separation rotor lamination cores 13 are jointed in an annular way.

摘要： PROBLEM TO BE SOLVED: To provide a small-size and thin-type resin-sealed semiconductor device which has no failure such as a resin peel off, lead drop-out, or the like, and which is superior in reliability. SOLUTION: A resin-sealed semiconductor device 10 has an element-mounting part 11 for mounting a semiconductor chip 22; a plurality of leads 12 provided in a periphery of the element mounting part 11, and a bonding wire 24 for electrically connecting an electrode pad 23 of the semiconductor chip 22 with a wire bonding part 19 formed at a top end part of the lead 12, and these are sealed with a resin so as to expose at least a bottom face of the lead 12. In this device 10, bent projection members 20, 21, which are cut into a sealing resin for putting-in, are provided at a position rearward of the wire bonding part 19 in the lead 12.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing divided core pieces by which method the volume of scraps is reduced and divided core pieces adjacent to each other are arranged in alternately shifted positions in the direction of feeding to allow efficient production, and to provide a stator core using the divided core pieces manufactured by the method. SOLUTION: The method for manufacturing the plurality of the divided core pieces 12 is used to be laminated on divided laminated cores 11 dividing a ring-like laminated core 10 into a plurality of those circumferentially, and forms a wider portion 13 set radially outside and a narrower portion 14 set radially inside respectively. The method includes a blanking process for blanking core piece groups 24 alternately arranging the divided core pieces 12 on a strip member 16 made of a magnetic material so that radial center lines m of each divided core piece 12 are parallel and a side end 22a of the narrower portion 14 of the divided core piece 12 adjacent to a side end 22 of the wider portion 13 is contacted, and a press working process for punching each divided core piece 12 by press working along blanking.
