The purpose of the present invention is to obtain a resin that is adjusted in advance, so that, in a configuration in which the resin is filled into gaps between wiring patterns, the influence of stress that occurs in the filled resin is reduced. An embedding resin according to the present invention is filled into gaps between wiring patterns of a circuit board. In a stack in which a base substrate, an insulating layer, and a resin portion that comprises the embedding resin are stacked in this order, the embedding resin has a coefficient of linear expansion and a Young's modulus that are configured so that the stress in the interface of the insulating layer that is in contact with the resin portion becomes 13.0 MPa or less when calculated by the formula σ = (P/bh) + (Ey/R) based on a 4-layer model using the temperature difference from room temperature to the glass transition temperature of the insulating layer. [Here, σ is the stress (MPa), P is the axial force (N), b is the depth measurement of the insulating layer (mm), h is the thickness of the insulating layer (mm), E is the Young's modulus (MPa), y is the distance from the neutral plane, and R is the radius of curvature (mm).]

When the operation lever (21) is moved after the lock release switch (40) is operated, a shift mechanism (15) switches to forward-side shift or backward-side shift in accordance with the output of a detector (26). If the lock release switch (40) is not operated, the operation lever (21) moves but the shift mechanism (15) is not actuated because no signal permitting a shift is output.

During the ship fixed point holding mode, the ship control device actuates the actuator on the basis of deviation between a target ship position and an actual ship position, and the time measurement unit starts measuring time at the moment when the actual ship position deviates from a time measurement start determination area including the target ship position. When the actual ship position does not return to a ship fixed point holding mode stop determination area including the target ship position from the start of time measurement until a specified time elapses, the ship control device ceases the ship fixed point holding mode.

Abstract

The present invention effectively suppresses displacement of segment coils in the axial direction of a core when the ends of segment coil leg parts are bent. This production method produces a stator (10) that comprises a plurality of segment coils (40) that are annularly arranged in a plurality of layers (46A, 46B, 46C) that overlap in the radial direction of a stator core (14). The production method involves a tool (74) that has teeth (76A, 76B, 76C) being moved by a robot manipulator (72) and the teeth (76A, 76B, 76C) being inserted between the ends of leg parts (42) of the layers (46A, 46B, 46C). The ends that engage the teeth (76A, 76B, 76C) are thereby bent so as to be substantially crank-shaped. Before the teeth (76A, 76B, 76C) are inserted between the ends, a restraining jig (86) is inserted between bend parts (44) of the segment coils (40) of the layers (46A, 46B, 46C) and an end surface (14A) of the stator core (14) that is on one side in the axial direction.

The problem addressed by the present invention is to provide a compression coil spring the fatigue resistance of which is improved by decreasing the quantity of coarsened pro-eutectoid ferrite grains that can become fracture origins. The present invention is a compression coil spring for which a steel rod with an equivalent circle diameter of 1.5–10.0 mm is used, wherein: a depth from the surface at which the value of the unloaded compressive residual stress is zero in roughly the direction of maximum principal stress when a compressive load is applied to the spring on the inner-diameter side of an arbitrary horizontal cross-section of an effective section is deemed a crossing point; and the compression coil spring has the following physical characteristics at the depth of the crossing point. (1) In a metallurgical microscope image captured at a magnification of 1000 after the metallic structure has been made to appear using an etching fluid, standardization of brightness values of an obtained observation gray-scale image is performed; and thereafter, if the mean brightness value is μ and the standard deviation for brightness values is σ, the equivalent circle diameter of the largest white structure after binarization processing has been performed with μ + 2σ as a threshold value for binarization is 10 μm or less. (2) The hardness is 500–700 HV.
