The method includes positioning an electronic component using main marks formed on a metal layer and mounting the electronic component on a second surface of the metal layer with an adhesive layer interposed between the metal layer and both of the electronic component and terminals; then burying the electronic component and the main marks in an insulating substrate; then removing part of the metal layer and forming a first window for exposing the main marks therefrom and a second window for exposing the adhesive layer including a position corresponding to the terminal therefrom; then using the exposed main marks as references and forming a laser via hole LVH reaching the terminal in the adhesive layer exposed from the second window; and thereby forming a wiring pattern from the metal layer electrically connected to the terminal through a first conductive via formed by plating the LVH with copper.

Disclosed is an edgewise wound coil manufacturing device for manufacturing an edgewise wound coil. The edgewise wound coil manufacturing device is provided with: a plurality of corners; a core having a recess formed between each pair of adjacent corners, and around which a flat wire is wrapped; a rotating part that forces the core to rotate around the central axis of the core; guide parts that hold the flat wire therebetween in the thickness direction, while guiding the flat wire in such a manner that the flat wire wraps around the core; a first moving part that forces at least one of the guide parts and the core to move in the approaching/receding direction of the other; and a controller that adjusts the amount that the first moving part moves such that the edgewise wound coil achieves the desired shape.

Disclosed is a method for producing a stator for a rotary electric machine, which involves preparing a stator core having a plurality of slots. Each of a plurality of coils is provided with a pair of coil ends, a first side, and a second side. The first side and/or the second side is inserted into the retaining groove of a jig, and each coil is set on the jig in a manner such that both coil ends extend further to the outside than the end surfaces of the jig in the axial direction thereof. The jig is disposed inside the stator core in the diameter direction. The space between the first side and the second side of the coil is expanded by applying pressing force to both coil ends from the axial direction of the stator core by means of a pressing member.

To provide a non-aqueous electrolyte secondary battery less subject to impact by vibration, impact, etc., and has stable characteristics. The non-aqueous electrolyte secondary battery includes: a positive electrode part in which a positive electrode active material layer is formed on a positive collector; a positive electrode which is provided with a positive electrode lead tab and which is integrally formed with the positive collector so as to be connected to a periphery of the positive electrode part through a curved portion continuing therefrom; a negative electrode part in which a negative electrode active material layer is formed on a negative collector; a negative electrode which is provided with a negative electrode lead tab and which is integrally formed with the negative collector so as to be connected to a periphery of the negative electrode part through a curved portion continuing therefrom; and a separator which is interposed between the positive and negative electrodes. A positive electrode active material layer is formed at least on both sides of the positive electrode lead tab, and a projection portion obtained by vertically projecting the positive electrode part on the negative electrode part exists inward an outline of the negative electrode active material layer.

[PROBLEMS] To provide a humidifier having excellent humidifying performance, pressure loss, volume efficiency, and durability and particularly suitably used for humidifying gases used in an on-vehicle fuel cell and an operating method for the humidifier. [MEANS FOR SOLVING PROBLEMS] This gas separator is characterized in that the upper and lower surfaces of the pleat elements of a pleat molding are covered by a plate having at least a set of intake and exhaust ports. The pleat molding is formed by pleating a compound membrane formed of a gas separating membrane and at least one layer of permeable reinforcement material. The pleat element is formed by disposing a reinforcement frame at the outer side part of the molding. The ratio (R=L/H) of a shortest distance (L) between the intake and exhaust ports to the height (H) of the pleat molding is 0.1 to 7.0, and the ratio (W/Le) of the width (W) to the length (Le) of the pleat molding is 0.3 to 10.0. The operating method for the humidifier is performed at the volume flow ratio of 200 or higher.

A worm gear is provided on a rotating shaft of an AF motor. A first supporting cylinder includes a gear portion and a receiving portion. A wheel gear, which is in engagement with the worm gear, is formed on an outer surface of the gear portion. A slit is formed at the receiving portion. A second supporting cylinder includes a supported portion which is placed in the receiving portion of the first supporting cylinder, and a receiving portion which supports an AF coupler. A gear is in engagement with a portion which connects the supported portion and the receiving portion of the 2nd supporting cylinder. A clutch spring is wound around the supported portion, being in contact with the outer surface of the supported portion. Both ends of the clutch spring cross each other and are in engagement with a pair of walls, of the slit, which are parallel to an axis of the receiving portion.

A connection terminal comprises a terminal connection unit and a blade spring. A male terminal is inserted in the terminal connection unit. The blade spring is disposed in the terminal connection unit and press-contacts with the male terminal by means of reacting force generated by flexure deformation thereof. Spring strength of a front area of the blade spring is weaker than that of a rear area of the blade spring, wherein the front area is located at one side of the blade spring from which the male terminal is inserted in the terminal connection unit.
