    摘要： An electronic part, particularly a microstructure contact having an overall length of the order of 5 mm for an electrical connector or the like is provided with a nickel oxide layer portion having a nickel oxide layer of the order of 50 to 5000 .ANG. in thickness formed by anode oxidizing process using a solution mainly consisting of an alkaline solution. The nickel oxide layer portion is located between a terminal portion of the electronic part to be soldered as in a surface mounting process and a contact portion continuous to and extending from the terminal portion. The nickel oxide layer has a width of the order of 0.2 to 1 mm in the longitudinal direction of the contact and has a performance preventing the flowing of molten solder, thereby effectively preventing the flowing and wicking due to wetting of solder of the solder-plated portion toward the other portions as in the surface mounting process.

    摘要： A pin contact of a connector includes a parallel portion which touches a contact portion of a contact spring portion of a socket contact when the pin contact is fitted into the socket contact, and an inclined portion to be inserted into the contact spring portion while forcibly opening the contact spring portion at the time of insertion. The inclined portion has a shape which is a combination of a curve portion and a linear portion, the curve portion being moderate in inclination in the area of a boundary point between the curve portion and the parallel portion while sharp in inclination in the area of a contact start point at a pointed end of the contact pin contact. The linear portion has a constant inclination angle. The insertion force of the pin contact increases linearly proportionally to the fitting depth of the pin contact into the socket contact while the linear portion is touching the contact spring portion, whereas the insertion force of the pin contact is kept constant regardless of the fitting depth while the curve portion is touching the contact spring portion of the socket contact at a point over the boundary point between the linear portion and the curve portion.

    摘要： The invention provides a simple method for forming a gap for an erasure head to improve the quality of this erasure head. A front core 3 constituting an erasure head H includes in configuration two magnetic substances 5 and a magnetic gap 6 made of a non-magnetic substance arranged between these two magnetic substances 5, in which the gap 6 made of the non-magnetic substance is bonded by adhesion or welding between those two magnetic substances 5. By this method, the gap can be formed free of an air bubble, with good mass-productivity, and inexpensively as compared to a prior art method of forming a gap by glass bonding.

    摘要： In a transformer including a low-voltage input coil, a high-voltage output coil disposed coaxially of the low-voltage input coil, and a core for magnetically connecting both of the coils together; the improvement comprising a first bobbin around which the low-voltage input coil is wound which first bobbin has an inner-diameter hole, wherein the core comprises a rod portion to be inserted into the inner-diameter hole of the first bobbin and a flange portion provided at one axial end of the rod portion. In another aspect of the invention, the transformer further comprises a second bobbin around which the high-voltage output coil is wound, and a connector adapted to be connected to an ignition plug which connector is mounted on an end surface of the second bobbin on the opposite side of the flange portion of the core in such a manner that a mounting direction of the connector substantially coincides with an axial direction of the second bobbin. In a further aspect of the invention, the transformer further comprises a shield case formed of a magnetic conductive material surrounding an outer periphery of the connector or entirely surrounding the transformer. The rod portion of the core may have a tapering cross section such that it is gradually tapered from a low voltage side of the high-voltage output coil to a high voltage side thereof. With this arrangement, the transformer may be easily assembled and made compact. Further, a magnetic efficiency may be improved, and an insulating distance between the low-voltage input coil and the high-voltage output coil may be ensured.
