摘要:
Leakage fluxes from windings and leads of a stationary induction apparatus are confined within a tank. The stationary induction apparatus includes an electric functional units each including a winding and a core, a tank containing the electric functional units, high-voltage leads leading out from the windings, and low-voltage leads leading out from the windings. Magnetic shields are placed on the inner surface of a wall of the tank through which the high-voltage leads are drawn out of the tank, and a composite shield formed by combining nonmagnetic shields and magnetic shields is placed on the inner surface of a wall of the tank facing the low-voltage leads and is electrically short-circuited.

摘要:
On a through-electrode (7) formed by filling a conductive material into a though hole of a substrate, nano-metal particles are adhered to form a connection electrode (9). An LED element (3) is electrically connected to the through-electrode (7) via the connection electrode (9). The nano-metal particles can be applied into a desired shape by an inkjet method or a dispenser method, and hence a light emitting device (1) having high electrical connection reliability is realized at low cost.

A urethane (meth)acrylate composition includes a product of a reaction of a polyester polyol made from a polycarboxylic acid and a polyhydric alcohol, a polyisocyanate, and an active hydrogen-containing (meth)acrylate. Part of the polyhydric alcohol is a diol having a straight chain of 3 to 7 carbon atoms and a side chain on the straight chain. The polyisocyanate includes at least one of hexamethylene diisocyanate, diphenylmethane diisocyanate, hydrogenated diphenylmethane diisocyanate, and tetramethylene diisocyanate.
摘要:
An electromagnetic relay has a solenoid formed from a wound coil, a movable iron core that is reciprocated upwardly and downwardly in an axial hole of the solenoid, and a movable contact point that reciprocates together with the movable iron core. The movable contact point is contacted and separated with and from a fixed contact point for opening and closing a contact point. An arc generated at a time of opening and closing of the contact point is flowed, in a predetermined direction, by the magnetic field of at least a single permanent magnet placed at a side of the fixed contact point and the movable contact point that are contacted and separated with and from each other. Coil terminals are connected to leader lines of the coil, at least at a single side of the flow of the arc.
