The objective is to provide a terminal that can be used in waterproof electric connectors without damaging the sealing member thereof and can reliably prevent the body and the spring from being deformed through reducing the load on the body and enhancing the strength of the body. The terminal according to the present invention comprises a rectangular-tube-shaped body being formed of a cross plate, a first vertical plate and a second vertical plate bending from both ends in the width direction of the cross plate and rising to one side in the thickness direction, an inner plate bending from the first vertical plate and extending in the width direction close to the second vertical plate, and an outer plate bending from the second vertical plate and extending in the width direction close to the first vertical plate to overlap with the inner plate, a connecting part extending from the body, and a laid-down protruding piece bending from the end in the width direction of the outer plate of the body to reverse in the width direction, extending in the width direction and having a width equal to or narrower than the width of the outer plate.

The orthodontic bracket according to the present invention is provided with ligating means having a simple configuration, has additional functions for improving therapeutic effect and improving aesthetic appearance and enables maintenance to be carried out easily. A movable slider portion 2 for pinching an upper portion and a lower portion of an archwire to hold the archwire is provided in order to hold the archwire with respect to a bracket body 1 that has a slot 5 for holding the archwire. This slider portion 2 is inserted into the bracket body 1 to thereby hold the archwire 6. An orthodontic bracket composed of the bracket body 1 and the slider portion 2 has aesthetic properties by having a rounded shape with few surface irregularities. The slider portion 2 can be readily moved with an operating tool 14 and can be easily attached and detached.

A pair of diagonal members are arranged to extend from a substantially central position of a rear end panel extending in a widthwise direction of a vehicle body toward respective junctions of rear frames and a cross member. An end of each of the diagonal members is jointed to the rear end panel, and the other end thereof is jointed to the rear frame together with an end of the cross member. In addition, a guard block protruding toward a bumper beam is detachably fixed to the substantially central position of the rear end panel. Thus, such a frame structure for a vehicle can disperse and absorb an impact load in a low-speed crash or an offset crash.

A seat has a configuration in which, in each side frame of a cushion frame, an inner frame and an outer frame which have flanges extending along peripheral edges thereof are faced to each other with a space therebetween at least partially, and the flanges are fixed by hemming process along the entire peripheral edges thereof. Since the entire peripheral edges are hemmed, the inner frame and the outer frame are securely fixed. Additionally, since the inner frame and the outer frame which are thin-plate-shaped are used, reduction in weight of each side frame can be achieved. Further, since the inner frame and the outer frame are faced to each other with a space therebetween at least partially, a compressive / tensile strength required as a side frame can be secured by inserting an expanded bead body into the space.

A small end member constituting a small end, a column member constituting a column portion, and a big end member constituting a big end of a connecting rod are formed as separate members. In addition, the small end member and the big end member are each made of a high-rigidity material, and the column member is made of a high-strength material. These members are integrally bonded by liquid phase diffusion bonding, thus providing a connecting rod that can achieve suppression of stress concentration.

A female crimp terminal includes a tubular body, a leaf spring contact inside the body and integrally extending from the front part of the body, a neck having a U shape when seen in the longitudinal direction and integrally extending from the lower parts of both side walls and the bottom wall at the rear end of the body, and a barrel having a U shape when seen in the longitudinal direction, integrally extending from the neck and having retainers extending upward high above the neck. A notch is made in a rear edge of each side wall from the rear end of the body so as to divide the side wall into an upper part and a lower part. This isolates crimping forces of the barrel from the tubular body which houses the leaf spring contact.

Each of contact terminals, provided on a substrate of an IC module so as to be positioned on a back surface of a surface having an IC chip, which are terminals other than a GND terminal, has a curved convex face, and the GND terminal has a curved concave face as a counter face opposite to the curved convex face of the contact terminal so that there is a constant gap between the curved convex face and the curved concave face, and a gap between the GND and each of the contact terminals other than the GND terminal is narrower than a gap between all the contact terminals other than the GND terminal provided on the substrate so as to be positioned on the back surface of the surface having the IC chip. Thus, it is possible to provide an IC module and an IC card each of which enables the IC card's strength with respect to bending to be secured, and facilitates process thereof, and enables the IC chip to be protected from static electricity.

A semiconductor device includes: a first substrate made of semiconductor and having first regions, which are insulated from each other and disposed in the first substrate; and a second substrate having electric conductivity and having second regions and insulation trenches. Each insulation trench penetrates the second substrate so that the second regions are insulated from each other. The first substrate provides a base substrate, and the second substrate provides a cap substrate. The second substrate is bonded to the first substrate so that a sealed space is provided between a predetermined surface region of the first substrate and the second substrate. The second regions include an extraction conductive region, which is coupled with a corresponding first region.

There are provided an aluminum-alloy clad sheet and a clad sheet subjected to heating equivalent to brazing, which each have a high strength and an excellent erosion resistance and thus allow a reduction in thickness of a clad sheet subjected to heating equivalent to brazing such as an aluminum alloy radiator tube, and / or of a clad sheet such as an aluminum-alloy brazing sheet. An aluminum-alloy clad sheet or a clad sheet subjected to heating equivalent to brazing includes at least a core aluminum alloy sheet and an aluminum-alloy sacrificial anti-corrosive material cladded with each other, and is to be formed into a heat exchanger by brazing. The core aluminum alloy sheet includes a specified 3000 series composition.
