Abstract:
A pressure structure which is arranged between a first pressed body and a second pressed body facing the first pressed body and applies a pressure to the first pressed body and the second pressed body includes: a first spring member including a center portion which is in contact with the first pressed body, two end portions, each of which is in contact with the second pressed body, and two arm portions which extend from the center portion toward the different end portions; and a second spring member including a center portion which is in contact with the second pressed body, two end portions, each of which is in contact with the first pressed body, and two arm portions which extend from the center portion toward the different end portions.
Abstract:
A spring forming device in which the steel wire can be continuously cut off without stopping the feeding of the steel wire in cutting, and in which the steel wire can be uniformly heated, is provided. The spring forming device has a wire supplying mechanism for supplying a steel wire using a plurality of feeding rollers, a heating mechanism for heating the steel wire, a coiling mechanism for forming in a coil state the heated steel wire, and a cutting mechanism for cutting the steel wire coiled at a given number of turns off the steel wire remained backward. A cutting blade of the cutting mechanism follows tracks having a speed Va that moves to the receiving blade and a speed Vc that moves in an axial direction of the coiled steel wire, in cutting of the steel wire.
Abstract:
In the bonding of the bush to the bar of the stabilizer, by surface pressure in the bonding surface (inner circumferential surface) of the hole part of the bush being made uniform, a necessary bonding strength can be obtained. The first arc part 101 is formed at the opposite side of the opening part of the U-shaped part 41 of the bracket 40 used in the bonding ( Fig. 3B ) and the second arc part 102 is formed in the opening part side, in the hole part 100A of the bush 100. The first arc part 101 and the second arc part 102 are the circular arc part being formed in the circular arc shape or approximately circular arc shape, for example, or are the ellipse arc part being formed in the ellipse arc shape or approximately ellipse arc shape, for example. In the hole part 100A, the center O1 of the first arc part 101 and the center 02 of the second arc part 102 are separated. The curvature radius r2 of the second arc part 102 is formed smaller than the curvature radius r1 of the first arc part 101. The hole part 100A is desirably formed in an oval shape as shown in Fig. 6 , for example.
Abstract:
Provided is a boot band 31 that is capable of preventing the occurrence of buckling in the inner-layer portion of a band body 33. In the boot band 31, by applying a diameter-reducing tightening force on the band body 33 when an engagement pawl 41 of the inner-layer portion 35 of the band body 33 has entered a top-end engagement hole 42 of the outer-layer portion 34 of the band body 33, the top-end engagement hole 42 rides over the engagement pawl 41. Buckling is prevented by providing, at the area of the top-end engagement hole 42 opposite where the engagement pawl 41 enters therein, a guide means 51 that faces the engagement pawl 41.
Abstract:
A knee-action-type suspension (11) is provided with an arm member (20), a compression coil spring (21), and a shock absorber (24). The arm member (20) is supported in such a way that it is pivotable in the upward and downward directions by a pivot (31) provided on an arm mounting portion (30). The coil spring (21) is arranged between spring seats (22, 23). The coil spring (21) is extended and retracted between a full-rebound state and a full-bump state in accordance with the magnitude of a load applied to a vehicle body. A wire (40) of the coil spring (21) includes a large-diameter wire portion (40a), a small-diameter wire portion (40b), and a wire diameter varying portion (40c). The large-diameter wire portion (40a) is provided in a first portion (21a) of the coil spring (21), which is on the side near to the pivot (31). The small-diameter wire portion (40b) is provided in a second portion (21b) of the coil spring (21), which is on the side far from the pivot (31). A wire diameter (d1) of the large-diameter wire portion (40a) is greater than a wire diameter (d2) of the small-diameter wire portion (40b).
Abstract:
A film forming method and a film forming apparatus are provided, which achieve: suppression of oxidation of a film being formed; a simple and inexpensive configuration of the apparatus; and replacement of a base member to be subjected to film formation without time and effort. A film forming apparatus 100 is a film forming apparatus that forms a film by accelerating powder 2 of a material with gas and spraying and depositing the powder 2 onto a surface of a substrate 1 with the powder 2 being kept in a solid state; the film forming apparatus 100 includes a chamber 10, a holding unit 11 that is provided in the chamber 10 and holds the base member 1, a spray nozzle 12 that jets out the powder with inert gas, and a drive unit 15 that moves any one of the spray nozzle 12 and holding unit 11 with respect to the other; and inside of the chamber 10 is caused to be under positive pressure by the inert gas jetted out from the spray nozzle 12.
