摘要： PURPOSE:To improve accuracy of pellet mount by improving adhesive strength of the pellet and a base material without generating cracks or cutouts by providing the loading mechanism which minimize the load applied to the pellet when the pellet makes contact with the base material and applys a desired load to the pellet when scrubbing. CONSTITUTION:When a contact roller 18 is touched to a nail-shaped projection 16a of a cam 16 for increasing the load gradually, a T-shaped lever 17 and a crank arm 19 are located in parallel to a supporting bar 1 and a swing arm 2 is also parallel to them at this time. When a collet 3 completely lowers, the load is 10-40g, for example. When the contact roller 18 is detached from the projection 16a of the cam 16, the T-shaped lever 17 falls down and a front end of the crank arm 16 turns upward to pull up a tension spring 22 thereby raising a rear end 2b of the swing arm 2 thereby lowering the collet 3. The collet 3 is applied with the load, for example, becoming 40-200g.

CONSTITUTION:Over a sharp edge 21 of iron-core yoke facing a high voltage winding end 51a and a low voltage winding end 52a, U-shaped supporting plates 41 and 42 for winding 51 and 52 are provided, and plates 45 and 46 are provided by extending the supporting plates 43 and 44. The plate 45 and 46 are faced to each other at the center of the top surface of the yoke. Plates 45a and 46a are extended outward on the core legs. The electlic field at the ends of the tightening metals are alleviated, and the coil is effectively supported. Sharp edges are not provided at the portions where the spaces between the plates 45 and 46 and 45a and 46a face the windings. In this cinstitution, grounding electrodes electrically opposing the winding ends 51a and 52a constitute the flat-plate parts of the coretightening metal, and do not face the sharp edge 21 of the iron core yoke. Thus the uneven part of the electric field is removed.

摘要： PURPOSE:To contrive the continuation of works, to improve the yield of manufacturing a semiconductor device and contrive the reduction of the number of working personnel concerned by coupling charging, transferring, marking, lead cutting and forming, and characteristic selecting units. CONSTITUTION:A magazine 24 filled with works coupled by a lead frame is mounted on a bench 22, and an operation is started. A weight 31 presses the works 32 to operate a supporting rod 29 and a pushing plate 34 so as to feed the works one by one, and to intermittently transfer and feed the works between the respective units by the actions of pawls 43 and the members 41 by a feeding machanism 20. A cleaning unit first cleans the printed surfaces of the works via rotating belt immersed with organic solvent, a making unit roll prints ultravoilet ray curable ink on the works, and ultraviolet ray lamps dry them. Subsequently, the works reach a cutting and forming unit 16, which cuts the burrs of the works, and dies 77, 79 cut the frame of the works, and forming unit 87 forms lead wires 6 at the works. Then, the works are pneumatically conveyed, are partly stored temporarily, and are fed to a sorter 18. The sorter 18 elevationally moves its body 100 up and down to insert the works into sockets 107 to measure and sort the works. The works are then sequentially fed through a passage 101. This configuration can efficiently and automatically process the works thoroughly and consistently.

摘要： PURPOSE:To facilitate work with simple structure by fixing a bind to one side of an L-shaped bind end metal fitment and turning the other side taking its corner section as a fulcrum. CONSTITUTION:A bind end metal fitment 8 is formed in L shape and a notch 15 is set up on its one side, then a bind hook piece 11 is welded to it like a bridge. A bolt hole 16 to be screwed in a flat plate shaped core clamping metal fitment 9 is set up on the other side. The bind end metal fitment 8 whose bind 5 is fixed to the hook piece 11 hooks in the stopper 17 of the core clamping metal fitment 9. This metal fitment 9 is mounted to a core bench 7 through a press metal fitment 8. A core 6 is clamped by appropriate clamping pressure by turning the bind end metal fitment 8 by alpha degrees taking the L-shaped corner section as the center of rotation like an arrow and fixing it by an end metal fitment fixed bolt 10. As a result, an easy to handle core clamping device with simple structure can be obtained.

摘要： PURPOSE:To hold stem positively and perform automatic pellet mounting smoothly by providing a magnetizing means to part of a guide plate for moving heat block and stem. CONSTITUTION:A heat block 1 is lowered and a stem 10 is supported by a guide plate 2 and is fed to the right or left. At this time, the guide plate 2 is magnetized with an electromagent 17 to positively hold the stem to the guide plate during moving. Next, the heat block ascends to float the stem from the guide plate, and the stem is supported and heated with the heat block. At this time, too, the heat block is magnetized by an electromagnet 16 to positively hold the stem to the block. In this state, a pellet 19 is mounted onto the stem. This constitution enables the stem 10 of iron, Ni, Co or their alloy to be accurately and rapidly fed and heated, thus automatic pellet mounting is smoothly accomplished.
