Abstract: An LED package includes: a molded interconnect device that has an LED chip mounted thereon, and is mounted on a mounting board electrically connected to the LED chip; and a plurality of elastic bodies mounted on the mounting board while interposing solder therebetween. The plurality of elastic bodies hold a position of the molded interconnect device with respect to the mounting board by elastic forces given to an inner surface side of the molded interconnect device from a plurality of outer side surfaces thereof opposite to each other.

Abstract: Provided is a pressure coupling connector which can decrease the number of components for coping with various electric wire diameters, prevent problems due to difference in product kind, and reduce the stock. The pressure coupling connector includes a wire holding block for holding electric wires and a contact block for holding a connection terminal to which the electric wire is coupled with pressure by inserting the wire holding block into the contact block. The connection terminal of the contact block includes a U-shaped blade rising toward an opening surface into which the wire holding block is inserted. The wire holding block includes a wire holding portion in which a holding hole for transmitting the electric wire from the rear side thereof and holding the electric wire is formed and a reception groove for receiving the U-shaped blade of the connection terminal.

Abstract: A memory card socket structure includes a case having a card accommodating portion for receiving a thin plate-shaped memory card, and a contact block having contact terminals to be brought into contact with terminals of the memory card. The case has a cover shell and a base shell both formed of metal plates, and the cover shell and the base shell are welded to each other by a laser welding.

Abstract: In order to obtain a 3D circuit board manufacturing method capable of improving productivity and accuracy of circuit formation, the metal hoop material 1 provided with the positioning pilot holes 2 is employed. Since the 3D structures 3 are formed on the hoop material 1 with a preset interval maintained therebetween in a lengthwise direction of the hoop material 1, the series of processes can be conducted on a roll 1A (winding of the hoop material 1) basis, which results that handling between the individual processes can be done more easily while increase of troubles and manufacturing costs can be prevented. Further, since the positioning pilot holes 2 serve to facilitate accurate positioning, plating and/or laser processing can be conducted continuously with high precision while a tact time for the positioning work can be reduced.

Abstract: An electromagnetic relay has a base provided with an insulation enclosure and with a contact block outwardly of the enclosure. An electromagnet block is received within the enclosure and includes a coil, yokes, and an armature extending through the coil along the length of the enclosure. The armature is magnetically coupled to the coil and is movable relative to the yokes upon energization of the coil. A card is provided to connect the armature and a movable contact of the contact block for closing and opening the contact. A cover fitted on the base includes an insulation partition which extends between the enclosure and the contact block to accomplish a double-wall insulation between the electromagnet and the contact block. The card has a trunk for connection with the armature and a crosspiece for connection with the movable contact.

Abstract: The acceleration applied to a selected device such as a magnetic disc drive system can be detected by the use of an acceleration detector having at least one piezoelectric acceleration sensor unit. The sensor unit includes a piezoelectric element, a supporting member for the piezoelectric element and two electrical leads. The piezoelectric element is formed with a pair of elongate sheets made of a piezoelectric ceramic and an intermediate insulation layer interposed between the elongate sheets to generate a voltage difference instantaneously therebetween in response to the acceleration of the acceleration detector. The support member is made of an electrically insulating resin, and has a concave which is formed with side and bottom walls and a top opening. The side wall is provided with a slit in which the piezoelectric element is tightly caught in such a manner as to divide the concave into two open-chambers and be supported by the support member in a cantilever fashion.

Abstract: A miniaturized electromagnet has an enhanced armature attraction force and reliable armature movement. The electromagnet comprises an L-shaped flat magnetic plate of magnetic material with a horizontally extending core and a first yoke leg depending from one end of the core. An excitation coil is wound around the core. A second yoke member is formed separately from the magnetic plate into a plate configuration and is coupled secured at its upper end to the other end of the core so as to depend therefrom in an opposed relation to the first yoke leg. The lower end portion of the second yoke leg is bent toward the first yoke leg to define thereat a pole plate extending parallel with the core.

Abstract: A polarized electromagnetic relay having a pair of first and second pole members which are magnetized to opposite polarity by a permanent magnet coupled thereto and which define therebetween a magnetic gap into which the other end of the armature extends. The first pole member and the armature are magnetically coupled to the base so as to cause a magnet flux of the permanent magnet to circulate through the second pole member, the armature, the base, and the first pole member for attracting the armature to the second pole member. Upon energization of the coil, a resulting coil flux circulates through the armature, the base, and the first pole member in opposing direction to the magnet flux for attracting the armature to the first pole member. A cover and base of magnetic material is included to fit over the base and be magnetically coupled thereto.
