Abstract: The present invention relates to a magnet wire bonding method and a bonding structure, and more particularly to a new improvement for ultrasonically bonding a longitudinal outer peripheral surface of a magnet wire having no entangling part to a flat surface of a flat part of a terminal pin. A magnet wire bonding method and structure, comprising: using a terminal pin (11) having a flat plate part (40) provided in a pin part (11a) as a terminal pin holding part (3); placing a magnet wire (13) in a longitudinally spread state on a flat surface (40a) of the flat plate part (40) without being entangled; and ultrasonically bonding an outer peripheral surface (13E) of the magnet wire (13) onto the flat surface (40a) with an ultrasonic horn (50).

Abstract: The present invention relates to a phase modulation-type redundant two-phase-output resolver, an excitation signal (100) is applied to an excitation winding (50) of an annular stator (21) having a VR-type rotor (20) disposed therein, and a two-phase output signal (101) is outputted from first and second output windings (43, 44) that are provided in the annular stator (21), the excitation winding (50) is made up of first and second excitation windings (40, 41) of mutually different phases, and the excitation signal (100) has two phases, and even in a case where a break occurs in only any one winding from among the first and second excitation windings (40, 41) and the first and second output windings (43, 44), at least a one-phase output signal can be obtained.

Abstract: A connector includes a plurality of terminals, a housing, and a retainer. The housing includes terminal housing chambers and partition portions. Each of the terminal housing chambers accommodates therein each of the plurality of terminals. Each of the partition portions is provided between adjacent terminal housing chambers and partition the adjacent terminal housing chambers from each other. The retainer is attached to the housing. The retainer is configured to prevent each of the terminals from falling out and to move between a temporary locking position and a proper locking position. The retainer includes communication cut portions. While the retainer is moving between the proper locking position and the temporary locking position, each of the communication cut portions is kept in contact with its corresponding partition portion and cut off communication between the adjacent terminal housing chambers.

Abstract: An infrared radiation element and a process for producing the same. An aluminum alloy material consists essentially of 0.3 to 4.3 weight % of Mn, balance Al, and impurities. The alluminum alloy material is heated for dispersing a precipitate of an Al--Mn intermetallic compound at a density of at a minimum 1.times.10.sup.5 /mm.sup.3 for a size of 0.1 .mu.m to 3 .mu.m. The heated aluminum alloy material is anodized to form an anodic oxide layer thereon.

Abstract: Herein disclosed is a material for making conductive parts such as lead frames or connectors of semiconductor elements or integrated circuits (i.e., ICs). The material is an aluminum-based alloy containing 0.3 to 4.0 wt. % of manganese and 0.10 to 5.0 wt. % of magnesium, the remainder being aluminum and unavoidable impurities. The material may additionally contain: at least one of copper and zinc; and/or at least one of chromium, zirconium, vanadium and nickel, if necessary. The material having the composition specified above can be made at a reasonable cost with excellent softening resistance, electric and thermal conductivities, solderability and platability, a high mechanical strength, and an excellent bending repeatability.

Abstract: A T4 tempered and straightened rolled sheet of the Al--Mg--Cu series aluminum-alloy which contains from 1.5 to 5.5% of Mg and from 0.18 to 1.5% of Cu as the essential alloying element, has excellent mechanical properties, an improved formability, of a non-generation of Luder's marks. After the T4 treatment and subsequent straightening, the sheet is subjected to heating to a temperature in the range of from 60.degree. to 360.degree. C., at a heating rate falling within the hatched region of FIG. 1 attached herewith, then holding within the hatched region of FIG. 2 attached herewith, and subsequently, cooling at a cooling rate falling within the hatched region of FIG. 1.

Abstract: Rolled aluminum alloy sheets having improved strength and formability are provided which are to be formed into parts for use in an application where a high strength is required after paint baking, for example, as automobile body sheets. The aluminum alloy has a composition consisting essentially of Si 1.2-2.5%, Mg 0.25-0.85%, Fe 0.05-0.4%, Cu 0.1-1.5%, and at least one of Mn 0.05-0.6%, Cr 0.05-0.3%, and Zr 0.05-0.15%, balance essentially aluminum.
